  • The Self-organization of Social Complexity in Group-Living Animals:
           Lessons From the DomWorld Model

      This review demonstrates that many patterns of complex social behavior in group-living animals, in particular primates, may emerge by self-organization from cognitively “simple” competitive and affiliative interactions among group members. We focus on the lessons learnt from the different versions of model DomWorld. In these computational models, virtual individuals are group-living, initiate aggression in a risk-sensitive way, and groom others if they think they will be defeated. We show that, unexpectedly, in these models almost all social patterns emerge automatically that have been assumed to be displayed for cognitively more sophisticated reasons. For example, the emerging triadic agonistic patterns comprise all types of coalitionary support (conservative, bridging, and revolutionary), its reciprocation, and reciprocation of contra-support or opposition. Further, grooming is reciprocated, exchanged for support, and shown in patterns of post-conflict affiliation, including those of “reconciliation” and “consolation,” with similar differences between a tolerant and intolerant dominance style as in empirical data. These patterns emerge mainly because agonistic interactions create a spatio-social structure within groups that influences the occurrence of other social interactions in unexpected ways. When these dominance interactions in the computer model are based on the winner-loser effect, inter-sexual dominance relations appear to depend on sex ratio and intensity of aggression. Females become more similar in rank to males the fiercer the aggression among group members is and, in groups with intense aggression, the more male-biased the Adult Sex Ratio is. Similar empirical patterns have been reported for fish, primates, and humans. In conclusion, the DomWorld models illustrate how individual-based models provide an excellent tool for finding cognitively simple explanations for complex patterns of social behavior. These models generate nonintuitive results by integrating social interactions and their consequences across different levels, i.e., those of the individual, relationships, and group.

  • Behavioral Evidence of Felt Emotions: Approaches, Inferences, and
           Refinements
    • Authors: Daniel M. Weary; Paula Droege; Victoria A. Braithwaite

      Felt emotional states are at the very heart of many concerns about animal welfare. However, some scholars express doubt that animals are able to have such experiences, and there is much debate about what types of evidence can be used to draw inferences regarding such feelings in animals. The objective of this review is to critically examine inferences regarding felt negative emotions in animals based on various types of experimental and observational evidence resulting from behavioral studies. This review takes three types of approach: the assessment of spontaneous responses to a noxious stimulus, changes in these responses following a drug treatment, and assessments of the animal's motivation to avoid the stimulus. In each case we provide examples from previous experiments and suggest refinements that overcome certain limitations to each approach. We suggest that studies using learned, flexible, context-dependent responses, and tasks involving discrimination and generalization of affective states induced by drugs may be especially useful. Although the various types of evidence can be used in combination to draw tentative inferences, conclusions regarding felt emotions still fall short of definitive. As an approach forward, we propose adopting an Affective Stance that posits specific felt emotions and tests the predictions that arise from this posit that are not predicted by other approaches to this issue.

  • Communication in Animal Social Networks: A Missing Link?
    • Authors: Lysanne Snijders; Marc Naguib
      Abstract: Publication date: Available online 9 March 2017

      Animal social networks and animal communication networks are key disciplines for understanding animal social behavior, yet these disciplines remain poorly integrated. In this review, we show how communication and social networks are inherently linked, with social signals reflecting and affecting social networks. Signals carry key information on the quality and direction of social connections and reveal social connections over long distances. Moreover, social signals can directly affect proximity among conspecifics, by facilitating social attraction and repulsion. Social signals thus mediate many of the social networks we observe. Throughout, we discuss a broad range of signal types and interactions, yet with a focus on acoustic signals and show how they reflect and affect social relationships. With this review we aim to inspire further integration of the social network and communication network disciplines, expecting that it will lead to new insights into the dynamics and evolution of animal social behavior.

      We report on 35years of research into behavior and ecology of the Australian sleepy lizard, Tiliqua rugosa. We describe the unusually long monogamous pairing period in this lizard before mating takes place each spring, and the long-term persistence of mating pairs, reforming each spring for up to 27years. We review hypotheses, observations, and experiments and conclude that females drive the pairing, becoming more receptive to males that have provided prolonged attention, because of the advantages they gain through greater awareness of approaching danger. We suggest that long-term pair fidelity has resulted from a higher reproductive efficiency between familiar partners. We then consider the broader social network structure in the sleepy lizard population, suggesting from our analyses that lizards make more contacts with their neighbors, sometimes agonistically, than if they were moving at random. There are few kin-based associations in the networks, but lizards with different personality types have different network positions. The broad social structure of the population is robust to ecological and environmental changes, although various network parameters are adjusted with different climate or habitat conditions. The overall social structure of the sleepy lizard population has an important role in transmission of parasites and pathogens. Finally we consider why this species is one of the very few reptiles for which stable social living has been reported. This may be because reptile social living is relatively under studied. Alternatively, we suggest, many reptile species may be constrained from evolving social structures, because they lack either the necessary cognitive ability or a strong defense against the high risk of pathogen transmission that comes from social living.

      In this review, we summarize studies using approaches from the fields of comparative cognition and behavioral ecology to further our understanding of communication and behavior, as well as cognition and perception. We focus on studies examining one species of songbird, black-capped chickadees (Poecile atricapillus). Black-capped chickadees have an extensive repertoire including tseet calls, gargle calls, chick-a-dee calls, and fee-bee songs that birds produce in numerous contexts. Both songs and calls are learned in this species and other chickadee species produce similar, but acoustically distinct vocalizations, allowing researchers to compare the vocal production and perception of phylogenetically close chickadee species. We discuss studies spanning both laboratory and field research utilizing techniques such as operant conditioning, developmental biology, behavioral neuroscience, and bioacoustics. Taken together, the results of these studies provide a deeper understanding into songbirds in general, and chickadees in particular, and the synthesis of work using approaches from the fields of comparative cognition and behavioral ecology will inform and inspire future integrative research in communication and cognition.

      Invasive species are a major conservation concern but provide an opportunity to examine the mechanisms and consequences of behavioral adaptation. Invasive species can act as novel predators, prey, and competitors; impose stress on species they encounter; and alter habitats. Behavior is often plastic and therefore is one of the first traits to respond to environmental perturbations. Here we illustrate behavioral adaptations to invasive species, primarily using a system of invasive fire ants that act as a novel predator on and prey for a native lizard and placing this in the context of other research. We show that behavioral adaptations to invasive species can increase fitness in the face of associated challenges and opportunities, but can expose adapted individuals to new pressures or maladapt them to previously existing selective pressures. As a result, behavioral adaptations to invasive species can be associated with changes in other traits, such as morphology or physiology, that either enhance the effectiveness of the behavior itself or increase fitness in the face of new pressures caused by the altered behavior.

      The environment experienced early in life can shape phenotypes lifelong, sometimes inducing major phenotypic change of key life history traits or behavioral strategies. Such lasting effects of developmental plasticity impact Darwinian fitness and should be subject to selection. Nevertheless, the adaptive value of developmental plasticity is still subject to ongoing debate. One key problem hampering the understanding of developmental plasticity is that its mechanisms and function are mostly studied in simple laboratory environments testing for the effects of only a single environmental factor during a single ontogenetic period. However, most natural environments are multidimensional and complex and environmental influences affect development at multiple ontogenetic stages. In the past years, a number of theoretical and experimental studies emerged, which address effects of more natural levels of environmental complexity. After a general introduction into theoretical and experimental approaches to the study of developmental plasticity, I review the main theoretical insights from these models and contrast them with experimental results obtained from long-lived vertebrates, to illustrate how incorporating natural levels of complexity can improve our understanding of phenotypic development. The review centers around two main questions: (1) When should environmental information influencing development be obtained and when is this information beneficial? (2) How is information obtained during multiple life stages or from multiple environmental parameters integrated during phenotypic development? Theoretical results about the temporal patterns of the use of environmental information and the integration of cues from different sources emphasize the importance of environmental predictability, reliability, and the value of information. The experimental evidence illustrates the necessity to evaluate fitness across the entire life of long-lived species, if we aim to test predictions from evolutionary models. Moreover, it suggests that we need models incorporating more of the complexities of “real life,” such as interactive effects of environmental components, or a deviation from simplistic assumptions about the temporal pattern of environmental predictability.

      Mating systems describe the usual number of mating partners, patterns of mate location, and patterns of parental care in populations and species. While most types of mating systems can be found in arthropods, scramble competition polygyny is likely to be very common based on the ecology of many insects and spiders. In this review we focus on terrestrial arthropods and assess how common this mating system is and discuss the behaviors and ecologies of populations that are likely to result in scramble competition. A particular interest is those systems where the wrong mate choice can carry significant costs for the male, such as through deception or sexual cannibalism. We conclude our review with future direction for research in scramble competition polygyny.

  • Covetable Corpses and Plastic Beetles—The Socioecological Behavior

      Among-individual variation in behavioral plasticity—the modification of behavior in response to changes in environment experienced by individuals—is increasingly recognized as an important, but relatively poorly understood, feature of organisms that facilitates adaptation to environmental change. It is expected to evolve when there is rapidly fluctuating or directional environmental change during the lifetime of individuals. This is particularly likely to occur in the context of reproductive behaviors, when the outcomes of unpredictable social interactions with other individuals during mating and parental care determine how selection acts on males and females and mating systems evolve. To better understand patterns of mating and parental care and organismal adaptation to environmental change, we need to know why there is so much variation in behavioral plasticity between and within species. Here we address this question using burying beetles as a model. Burying beetles have unusually variable, facultatively expressed, modes of parental care and variation between the sexes and among individuals in the plasticity of reproductive behaviors. We present evidence to show that variation in male plasticity of mating behavior is a key driver of the evolution of patterns of parental care in Nicrophorus vespilloides burying beetles. More generally, we conclude that behavioral plasticity in burying beetles, and likely other taxa, has evolved as a consequence of a resource requirement bottle-neck (niche specialization) in combination with highly unpredictable availability of such suitable resources and the social unpredictability that arises as a result: constraint is the mother of plastic invention.

      The problem of cooperation has long been a central issue in evolutionary biology and psychology, although these disciplines approach the problem from different directions. In little over a decade, there have been great advances in experiments that bridge the psychological and evolutionary domains. By testing nonhuman primates, this work is trying to determine the phylogenetic roots of human sociality and the cognitive structures that scaffold this transition. In trying to understand prosocial behavior which is motivated for the welfare of others, researchers need to be aware of look-alikes. There are numerous examples of behaviors that appear prosocial, but are performed for the actor's benefit with any benefits to others arising as unintended by-products. Observations of natural behavior are suggestive, but experiments are needed to tease apart the alternative explanations. Even with experiments, it is challenging to interpret the findings. In this review, I critically discuss the experimental studies that have been designed to test for prosocial behavior in nonhuman primates. It is too early to conclude from these studies that chimpanzees and other nonhuman primates share with humans the motivation to share and help. Humans may be the only prosocial primate.

  • Variable Signals in a Complex World: Shifting Views of Within-Individual
           Variability in Sexual Display Traits

      Sexually selected display traits—whether they are color patches, songs, dances, or scents—typically vary over time and space, either due to changes in how those traits are perceived or due to changes in the source signal per se. Despite this variability, models of sexual selection typically characterize signalers with a single trait value. Thus, when variation in display traits is detected in empirical studies, it is often viewed as noise with little significance in communication, except in making traits more difficult to assess. This null hypothesis may be valid in some cases; however, studies are increasingly finding that variation in display traits may be the result of adaptive plasticity in display behaviors, and that this plasticity may have important implications for mate choice. Here we present a framework of alternative hypotheses to explain selective factors favoring variability in individual display traits—that variability is an indicator of current condition, a consequence of display refinement, or a reflection of adaptive plasticity in response to the social and environmental context of courtship to reduce their costs and maximize their benefits. We discuss predictions of these hypotheses and how they may be tested. Further, we discuss the implications of within-individual variability on selection for traits and preferences and the importance of considering the temporal scales over which courtship occurs. We conclude by identifying promising areas for theoretical development. By examining the causes and consequences of variation in display traits within individuals, we will gain a greater understanding of the scope of natural and sexual selection in shaping the diversity and complexity of sexual signals and signaling behaviors.

      Behavioral innovations, the invention of new behaviors or the use of preexisting ones in new contexts, are increasingly considered an essential source of behavioral plasticity, yet the mechanisms by which they arise are poorly understood. In recent years, much emphasis has been placed on the role of cognition. Here, we review briefly key findings from large-scale comparative research and, in more detail, those from experimental work on innovation. We draw attention to the high degree of inconsistency among empirical findings relating interindividual variation in innovativeness to interindividual variation in learning performance. We go on to propose a model that reconciles the possible (but perhaps controversial) existence of positive associations between cognition and innovation at the cross-taxon level with inconsistent associations at the within-species level. A key component of the model is the possibility that the association between cognition (ie, brain size) and innovativeness is not causal. Rather, it arises as a consequence of correlated evolution because both cognition and diet generalism evolve in response to environmental variability. Furthermore, motor diversity constitutes a proximate link between diet generalism and innovativeness.

      Hormones are major physiological signals through which individuals flexibly adjust behavioral phenotypes to fluctuations in external and internal conditions. In vertebrates, glucocorticoid (GC) hormones contribute to such phenotypic flexibility, coordinating changes in metabolism, behavior, and the endocrine stress response. While the mechanisms of GC action are increasingly being understood, their phenotypic effects within- and among individuals, and the resulting evolutionary processes have only recently become a focus in behavioral endocrinology. To date, basic questions regarding hormonal phenotypes remain unanswered, including their temporal stability (repeatability), genetic and environmental determinants, heritability in natural populations, and potential for evolutionary changes following environmental shifts. To address these issues, we first review the regulation and actions of GCs, summarize their modulation by external and internal factors, and highlight current concepts explaining GC dynamics. Second, we describe recent work that quantified the repeatability of GC traits, emphasizing the need to parse variation within and among individuals in GCs and in the behavioral traits they mediate. Third, we evaluate our current knowledge concerning the heritability of GC traits and their response to artificial selection, followed by an assessment of the extent to which variation in GC and GC-mediated traits has functional implications. Last, we discuss useful experimental and analytical approaches for characterizing phenotypic flexibility in GCs, outline some of the proximate pathways through which variability within and among individuals can arise and the functional consequences of GC-mediated flexibility. Throughout this review, we suggest promising research avenues to advance our understanding of the evolution of hormonal mediation of behavioral phenotypes.

      Communication is critical for spiders, as they are predatory and potentially cannibalistic and thereby positioned uniquely at the intersection of sexual and natural selection. Perhaps as a consequence, spiders exhibit a great diversity of communication behaviors. Spiders communicate using several sensory modes (vibratory, chemical, and visual) in multiple contexts. The subject of communication in spiders has been of growing interest to animal behaviorists and evolutionary biologists in recent decades, and despite an overall dearth of information, several recent reviews have stimulated new research. In this review, we briefly examine production, reception, and information content of spider signals and the various contexts in which communication occurs. We will then focus on wolf spiders, as they are among the best studied, and highlight some more detailed examples from our own work with video and vibratory playback experiments on Schizocosa ocreata (Hentz) as well as some other well-studied species.

      Empirical studies of contest behavior in anuran amphibians date back to the birth of behavioral ecology. Over the intervening years, considerable evidence has accumulated regarding two specific contest-related behaviors: the assessment and recognition of competitive rivals based on the exchange of vocal signals. In the first part of this chapter, we review studies of anurans that focused on the assessment of a rival's size and resource-holding potential, the honesty of signals used in assessment, graded variation in aggressive vocalizations, and the use of other, nonauditory sensory modalities for assessment. We emphasize problems of interpretation arising from the fact that much of this empirical work predates more recent and sophisticated theoretical treatments of assessment. In the second part of the chapter, we turn to rival assessment in the form of recognition between territorial neighbors (the “dear enemy” effect). After reviewing studies of neighbor recognition, we critically examine studies that have explicitly investigated components of rival recognition systems in anurans. The take-home message of this chapter is that despite significant advances in the study of contest behaviors in anurans, clear explanations for the diversity observed in the assessment and recognition of competitive rivals in this group are still lacking. We conclude by outlining important research directions in which future advances could be made regarding the function, evolution, and mechanisms of rival assessment and recognition.

      Extreme reproductive skew towards particular females is a defining feature of the eusocial Hymenoptera and workers are completely sterile in at least 13 genera. The evolution of worker sterility is problematic because an individual that has decreased fertility has reduced direct fitness. Here we review the major theories that seek to explain the evolution of eusociality and discuss how “genes for altruism,” in terms of reproduction, might be identified. We then review the experimental approaches used to identify the genetic basis of worker sterility, particularly in honey bees. Eight gene signaling pathways are likely to be involved in regulating worker fertility: insulin/insulin-like growth factor 1 signaling (IIS); juvenile hormone; ecdysteroid; mechanistic target of rapamycin (mTOR); dopamine; mitogen-activated protein kinases (MAPK); epidermal growth factor receptor (Egfr), and wingless-related MMTV integration site (Wnt). We focus our discussion of the developmental mechanisms that underlie worker sterility on specific “reproductive control points” that regulate worker fertility both pre- and post-eclosion. We propose that environmental cues (such as queen pheromone) interact with particular signaling pathways to regulate the control points and reduce the reproductive capacity of the worker. We suggest that the mechanism common to all the control points, and therefore underlying worker sterility, is programmed cell death. Our review concludes with a mechanistic scenario for the evolution of worker sterility.

      Rodents have long been recognized as an ideal model group for studying vertebrate sperm competition, since they exhibit very wide diversity in mating systems and are amenable to both experimental and comparative research approaches. From a strong initial focus on copulatory behavior and patterns of paternity, a new generation of studies is now revealing adaptive variation in diverse male reproductive traits, aided by methodological advances that most recently include postgenomic approaches. Here we aim to assess the current state of knowledge about rodent sperm competition and demonstrate how recent progress is building a more integrated view of the evolution of male reproductive phenotypes. Surveying research across six key male reproductive traits—copulatory behavior, sperm production, sperm allocation, sperm quality, seminal fluid, and genitalia—our review reveals a rich catalog of male adaptations to sperm competition in rodents. Recent molecular and genome-based approaches are already transforming our understanding of these traits, closing the gap between genotypic and phenotypic perspectives on their adaptive evolution. Significant future challenges lie in integrating female roles in postcopulatory sexual selection, and in judging the relative importance of the myriad male adaptations to sperm competition, both in relation to one another in determining competitive fertilization ability and compared to other sexually selected traits in explaining differential reproductive success.

  • Animal Welfare and the Paradox of Animal Consciousness

      Animal welfare science has a potentially paradoxical attitude to animal consciousness. On the one hand, the belief that animals are conscious is what draws people to want to study animal welfare, but on the other, consciousness remains ‘the hard problem’ and seems currently to be beyond the usual methods of science. This article asks whether the study of animal welfare that includes ‘feelings’ can be truly scientific by examining changing scientific attitudes to studying consciousness that have taken place over the last 50 years. Human psychologists have a similar problem in studying human consciousness and their findings provide a framework for studying feelings in nonhuman animals. Animal welfare scientists have at least four different ways of dealing with the potential paradox of animal consciousness. These are the following: (1) To argue that there are no problems and so there is no paradox (2) To admit the difficulties of studying consciousness and to settle for the next best thing—the likely (but not certain) behavioral correlates of consciousness (3) To admit the difficulties but then try to find ways of studying consciousness more directly (4) To ignore the problem altogether and concentrate on studying animal welfare in ways that are independent of assumptions about animal consciousness. I conclude that it is possible to have a science of animal welfare that avoids being paradoxical and is able to make a genuine contribution to the greatest remaining mystery in biology—why suffering, pleasure, and pain feel like anything at all.

      In recent years, behavioral ecologists have embraced social network analysis (SNA) in order to explore the structure of animal societies and the functional consequences of that structure. We provide a conceptual introduction to the field that focuses on historical developments, as well as on novel insights generated by recent work. First, we discuss major advances in the analysis of nonhuman societies, culminating in the use of SNA by behavioral ecologists. Next, we discuss how network-based approaches have enhanced our understanding of social structure and behavior over the past decade, focusing on: (1) information transmission, (2) collective behaviors, (3) animal personality, and (4) cooperation. These behaviors and phenomena possess several features—e.g., indirect effects, emergent properties—that network analysis is well equipped to handle. Finally, we highlight recent developments in SNA that are allowing behavioral ecologists to address increasingly sophisticated questions regarding the structure and function of animal sociality.

  • Sentinel Behavior: A Review and Prospectus

      Sentinel behavior can be defined as coordinated vigilance, usually from exposed positions. The literature contains anecdotes of sentinel behavior in many species, yet most of these anecdotes simply label particularly vigilant individuals as sentinels. Coordination has been documented quantitatively for only two species and verbally described for a few other species. Pending quantitative tests, we may regard sentinel behavior as repeatedly hypothesized but rarely documented. To further quantitative tests, a method of comparing the observed gaps without sentinels to those expected by chance is described and illustrated using data available from the literature. Sentinel behavior varies with ecological and social conditions. Natural rates of feeding correlate broadly with rates of sentinel behavior, and experimental food supplements have increased sentinel behavior dramatically. Sentinels generally are far more likely to detect predators and give alarm calls than are foragers. Although all individuals may engage in sentinel behavior, it tends to be more common in adults and males. Individual rates of sentinel behavior sometimes decrease with group size, though this effect seems to vary across species and even seasons. Sentinels often give calls besides alarm calls, yet these do not function simply as termination or continuity signals. Foragers are sometimes closer to cover than sentinels and sometimes farther away. Overall, the evidence is consistent with sentinels being safer than foragers. Evidence now exists that sentinel behavior functions, at least in part, to protect vulnerable juveniles. Therefore sentinels may be safe but should not be described as selfish.

      Economic escape theory refers to the escape decisions prey make based on their assessment of the costs and benefits of fleeing. In 1986, Ydenberg and Dill published a seminal paper in Advances in the Study of Behavior that developed the first cost-benefit models of escape. Here, we focus on flight initiation distance (FID), the predator-prey distance when the prey flees. Major predictions include that FID should increase as predation risk increases, and to decrease as the cost of fleeing (mainly through lost opportunity to forage and to engage in social behavior) increases. These, and other, predictions have been consistently supported by many studies on a variety of taxa. In 2003, Blumstein reported that FID increased as the distance that an experimenter began an experimental approach increased. Initially, this was thought not to be readily interpretable using economic escape theory. However, recent developments have shown how this relationship can be incorporated into economic escape theory and have raised new issues about a mathematical constraint that causes a positive correlation between FID and starting distance (SD), the effect of movements by prey not motivated by an approaching predator, and the use of SD as a proxy for the distance at which a prey begins to actively monitor the predator (alert distance). We discuss findings in regard to these issues and suggest potentially fruitful avenues for further research.

      The degree to which culture and cultural evolution are unique to humans has been a subject of continuous debate in the biological and social sciences. Bird song provides one of the most convincing animal examples, and the study of song learning and cultural transmission in chaffinches (Fringilla coelebs) has been central in this research, but has not been reviewed systematically. Not only can the classic work on song learning in chaffinches by Thorpe and Marler be said to have kick-started the field of vocal learning and traditions in animals, but subsequent work in this species has provided an exceptional depth and breadth of data on geographic variation in song and its cultural evolution. Here we review the work on chaffinch song that has been carried out in the 60 or so years since Thorpe and Marler's pioneering studies. In addition to further work on vocal learning and on dialects, the chaffinch has become a prime subject for studies of cultural evolution, particularly through studies on the Atlantic islands, as well as in Britain, Europe, and New Zealand. As well as describing such studies, we identify further areas likely to be fruitful for research on this species, which remains one of the icons of bird song research.

  • Avian Navigation: A Combination of Innate and Learned Mechanisms

      In the past 50 years, the field of animal navigation has been growing fast. The birds are by far the best studied group, and their orientation mechanisms are better known than that of other vertebrates or invertebrates. In this review, we will summarize our present knowledge on avian navigation, focusing (1) on the avian compass mechanisms and their interrelations and (2) on the mechanisms setting the course, like navigation based on site-specific information, navigation based on information obtained during the outward journey, and in case of juvenile first-time migrants, the innate program leading the young birds to their wintering area. We will also discuss the factors providing navigational information as far as they are known.

  • Chapter One Human Sperm Competition Playing a Defensive Strategy

      Sperm competition is the competition between the sperm of two or more males to fertilize the ova of a single female. Over the past few decades, the extent to which sperm competition has acted as a selective pressure throughout human evolution has been hotly contested. This review aims to assess the current evidence for sperm competition in humans, the limitations of that evidence, and directions for future research. We conclude that humans have primarily evolved defensive adaptations in response to the risk of sperm competition. Thus, men exhibit behaviors that anticipate and address their partner's infidelity, the success of which may have relaxed selection on physiological and morphological adaptations to tackle sperm competition offensively. However, the extent to which humans can perform offensive tactics has been sorely understudied and requires considerable further research before firm conclusions can be drawn.
