  • Ediacaran Extinction and Cambrian Explosion
    • Abstract: Publication date: Available online 12 July 2018Source: Trends in Ecology & EvolutionAuthor(s): Simon A.F. Darroch, Emily F. Smith, Marc Laflamme, Douglas H. ErwinThe Ediacaran–Cambrian (E–C) transition marks the most important geobiological revolution of the past billion years, including the Earth’s first crisis of macroscopic eukaryotic life, and its most spectacular evolutionary diversification. Here, we describe competing models for late Ediacaran extinction, summarize evidence for these models, and outline key questions which will drive research on this interval. We argue that the paleontological data suggest two pulses of extinction – one at the White Sea–Nama transition, which ushers in a recognizably metazoan fauna (the ‘Wormworld’), and a second pulse at the E–C boundary itself. We argue that this latest Ediacaran fauna has more in common with the Cambrian than the earlier Ediacaran, and thus may represent the earliest phase of the Cambrian Explosion.
       
  • Adaptive Networks for Restoration Ecology
    • Abstract: Publication date: Available online 11 July 2018Source: Trends in Ecology & EvolutionAuthor(s): Rafael L.G. Raimundo, Paulo R. Guimarães, Darren M. EvansThe urgent need to restore biodiversity and ecosystem functioning challenges ecology as a predictive science. Restoration ecology would benefit from evolutionary principles embedded within a framework that combines adaptive network models and the phylogenetic structure of ecological interactions. Adaptive network models capture feedbacks between trait evolution, species abundances, and interactions to explain resilience and functional diversity within communities. Phylogenetically-structured network data, increasingly available via next-generation sequencing, inform constraints affecting interaction rewiring. Combined, these approaches can predict eco-evolutionary changes triggered by community manipulation practices, such as translocations and eradications of invasive species. We discuss theoretical and methodological opportunities to bridge network models and data from restoration projects and propose how this can be applied to the functional restoration of ecological interactions.
       
  • Did Our Species Evolve in Subdivided Populations across Africa, and Why
           Does It Matter'
    • Abstract: Publication date: Available online 11 July 2018Source: Trends in Ecology & EvolutionAuthor(s): Eleanor M.L. Scerri, Mark G. Thomas, Andrea Manica, Philipp Gunz, Jay T. Stock, Chris Stringer, Matt Grove, Huw S. Groucutt, Axel Timmermann, G. Philip Rightmire, Francesco d’Errico, Christian A. Tryon, Nick A. Drake, Alison S. Brooks, Robin W. Dennell, Richard Durbin, Brenna M. Henn, Julia Lee-Thorp, Peter deMenocal, Michael D. PetragliaWe challenge the view that our species, Homo sapiens, evolved within a single population and/or region of Africa. The chronology and physical diversity of Pleistocene human fossils suggest that morphologically varied populations pertaining to the H. sapiens clade lived throughout Africa. Similarly, the African archaeological record demonstrates the polycentric origin and persistence of regionally distinct Pleistocene material culture in a variety of paleoecological settings. Genetic studies also indicate that present-day population structure within Africa extends to deep times, paralleling a paleoenvironmental record of shifting and fractured habitable zones. We argue that these fields support an emerging view of a highly structured African prehistory that should be considered in human evolutionary inferences, prompting new interpretations, questions, and interdisciplinary research directions.
       
  • Funder Restrictions on Application Numbers Lead to Chaos
    • Abstract: Publication date: Available online 11 July 2018Source: Trends in Ecology & EvolutionAuthor(s): Daniel J. Bearup, Dylan Z. Childs, Robert P. FreckletonRestricting application rates is an attractive way for funders to reduce time and money wasted evaluating uncompetitive applications. However, mathematical models show that this could induce chaotic cycles in total application numbers, increasing uncertainty in the funding process. One emergent property is that smaller institutions spend disproportionally more time unfunded.
       
  • Overcoming the Data Crisis in Biodiversity Conservation
    • Abstract: Publication date: Available online 7 July 2018Source: Trends in Ecology & EvolutionAuthor(s): Holly K. Kindsvater, Nicholas K. Dulvy, Cat Horswill, Maria-José Juan-Jordá, Marc Mangel, Jason MatthiopoulosHow can we track population trends when monitoring data are sparse' Population declines can go undetected, despite ongoing threats. For example, only one of every 200 harvested species are monitored. This gap leads to uncertainty about the seriousness of declines and hampers effective conservation. Collecting more data is important, but we can also make better use of existing information. Prior knowledge of physiology, life history, and community ecology can be used to inform population models. Additionally, in multispecies models, information can be shared among taxa based on phylogenetic, spatial, or temporal proximity. By exploiting generalities across species that share evolutionary or ecological characteristics within Bayesian hierarchical models, we can fill crucial gaps in the assessment of species’ status with unparalleled quantitative rigor.
       
  • Selection for Gaia across Multiple Scales
    • Abstract: Publication date: Available online 2 July 2018Source: Trends in Ecology & EvolutionAuthor(s): Timothy M. Lenton, Stuart J. Daines, James G. Dyke, Arwen E. Nicholson, David M. Wilkinson, Hywel T.P. WilliamsRecently postulated mechanisms and models can help explain the enduring ‘Gaia’ puzzle of environmental regulation mediated by life. Natural selection can produce nutrient recycling at local scales and regulation of heterogeneous environmental variables at ecosystem scales. However, global-scale environmental regulation involves a temporal and spatial decoupling of effects from actors that makes conventional evolutionary explanations problematic. Instead, global regulation can emerge by a process of ‘sequential selection’ in which systems that destabilize their environment are short-lived and result in extinctions and reorganizations until a stable attractor is found. Such persistence-enhancing properties can in turn increase the likelihood of acquiring further persistence-enhancing properties through ‘selection by survival alone’. Thus, Earth system feedbacks provide a filter for persistent combinations of macroevolutionary innovations.

  • Bridgehead Effects and Role of Adaptive Evolution in Invasive Populations
    • Abstract: Publication date: July 2018Source: Trends in Ecology & Evolution, Volume 33, Issue 7Author(s): Cleo Bertelsmeier, Laurent KellerBiological invasions are a major threat to biodiversity, agriculture, and human health. Invasive populations can be the source of additional new introductions, leading to a self-accelerating process whereby invasion begets invasion. This phenomenon, coined bridgehead effect, has been proposed to stem from the evolution of higher invasiveness in a primary introduced population. There is, however, no conclusive evidence that the success of bridgehead populations stems from the evolution of increased invasiveness. Instead, we argue that a high frequency of secondary introductions can be explained by increased abundance in the bridgehead region or the topology of human transport networks. We outline the type of evidence and experiments that are needed to demonstrate adaptive evolution and higher invasion success of introduced populations.

  • Social Information Links Individual Behavior to Population and Community
           Dynamics
    • Abstract: Publication date: July 2018Source: Trends in Ecology & Evolution, Volume 33, Issue 7Author(s): Michael A. Gil, Andrew M. Hein, Orr Spiegel, Marissa L. Baskett, Andrew SihWhen individual animals make decisions, they routinely use information produced intentionally or unintentionally by other individuals. Despite its prevalence and established fitness consequences, the effects of such social information on ecological dynamics remain poorly understood. Here, we synthesize results from ecology, evolutionary biology, and animal behavior to show how the use of social information can profoundly influence the dynamics of populations and communities. We combine recent theoretical and empirical results and introduce simple population models to illustrate how social information use can drive positive density-dependent growth of populations and communities (Allee effects). Furthermore, social information can shift the nature and strength of species interactions, change the outcome of competition, and potentially increase extinction risk in harvested populations and communities.
       
  • β-Diversity, Community Assembly, and Ecosystem Functioning
    • Abstract: Publication date: July 2018Source: Trends in Ecology & Evolution, Volume 33, Issue 7Author(s): Akira S. Mori, Forest Isbell, Rupert SeidlEvidence is increasing for positive effects of α-diversity on ecosystem functioning. We highlight here the crucial role of β-diversity – a hitherto underexplored facet of biodiversity – for a better process-level understanding of biodiversity change and its consequences for ecosystems. A focus on β-diversity has the potential to improve predictions of natural and anthropogenic influences on diversity and ecosystem functioning. However, linking the causes and consequences of biodiversity change is complex because species assemblages in nature are shaped by many factors simultaneously, including disturbance, environmental heterogeneity, deterministic niche factors, and stochasticity. Because variability and change are ubiquitous in ecosystems, acknowledging these inherent properties of nature is an essential step for further advancing scientific knowledge of biodiversity–ecosystem functioning in theory and practice.
       
  • Abrupt Change in Ecological Systems: Inference and Diagnosis
    • Abstract: Publication date: July 2018Source: Trends in Ecology & Evolution, Volume 33, Issue 7Author(s): Zak Ratajczak, Stephen R. Carpenter, Anthony R. Ives, Christopher J. Kucharik, Tanjona Ramiadantsoa, M. Allison Stegner, John W. Williams, Jien Zhang, Monica G. TurnerAbrupt ecological changes are, by definition, those that occur over short periods of time relative to typical rates of change for a given ecosystem. The potential for such changes is growing due to anthropogenic pressures, which challenges the resilience of societies and ecosystems. Abrupt ecological changes are difficult to diagnose because they can arise from a variety of circumstances, including rapid changes in external drivers (e.g., climate, or resource extraction), nonlinear responses to gradual changes in drivers, and interactions among multiple drivers and disturbances. We synthesize strategies for identifying causes of abrupt ecological change and highlight instances where abrupt changes are likely. Diagnosing abrupt changes and inferring causation are increasingly important as society seek to adapt to rapid, multifaceted environmental changes.
       
  • Deciphering the Interdependence between Ecological and Evolutionary
           Networks
    • Abstract: Publication date: July 2018Source: Trends in Ecology & Evolution, Volume 33, Issue 7Author(s): Carlos J. Melián, Blake Matthews, Cecilia S. de Andreazzi, Jorge P. Rodríguez, Luke J. Harmon, Miguel A. FortunaBiological systems consist of elements that interact within and across hierarchical levels. For example, interactions among genes determine traits of individuals, competitive and cooperative interactions among individuals influence population dynamics, and interactions among species affect the dynamics of communities and ecosystem processes. Such systems can be represented as hierarchical networks, but can have complex dynamics when interdependencies among levels of the hierarchy occur. We propose integrating ecological and evolutionary processes in hierarchical networks to explore interdependencies in biological systems. We connect gene networks underlying predator–prey trait distributions to food webs. Our approach addresses longstanding questions about how complex traits and intraspecific trait variation affect the interdependencies among biological levels and the stability of meta-ecosystems.
       
  • Physical Stress, Consumer Control, and New Theory in Ecology
    • Abstract: Publication date: July 2018Source: Trends in Ecology & Evolution, Volume 33, Issue 7Author(s): Brian R. Silliman, Qiang HeConsumer–prey interactions form the foundation of food webs and are affected by the physical environment. Multiple foundational theories in ecology [e.g., the environmental stress model (ESM), the stress–gradient hypothesis (SGH), and ecosystem resilience theory] assume increased physical stress dampens top-down control of prey. In the large majority of empirical studies, however, physical stress either does not affect or amplifies consumer control. Additive and synergistic impacts of physical stress on consumer control appear more common, for example, for herbivory versus predation, and for warm- versus cold-blooded consumers. Predictability in how physical stress affects consumer control, however, remains largely unknown. We expand classical theories in ecology so that their assumption about physical stress–consumer control relationships can be inclusive of what primarily occurs in nature.
       
  • Anagenesis, Cladogenesis, and Speciation on Islands
    • Abstract: Publication date: July 2018Source: Trends in Ecology & Evolution, Volume 33, Issue 7Author(s): Brent C. Emerson, Jairo PatiñoAnagenesis and cladogenesis are fundamental evolutionary concepts, but are increasingly being adopted as speciation models in the field of island biogeography. Here, we review the origin of the terms ‘anagenetic’ and ‘cladogenetic’ speciation, critique their utility, and finally suggest alternative terminology that better describes the geographical relationships of insular sister species.
       
  • Lessons in Lateralisation from the Insects
    • Abstract: Publication date: July 2018Source: Trends in Ecology & Evolution, Volume 33, Issue 7Author(s): Jeremy E. Niven, Adrian T.A. BellThe behavioural lateralisation of a species is thought to be influenced by social organisation. However, recent studies of insect species with different social structures suggest that traits showing both population-level and individual-level lateralisation can be found in single species. This has broad implications for our understanding of how lateralisation and handedness evolves.
       
  • Plant Camouflage: Ecology, Evolution, and Implications
    • Abstract: Publication date: Available online 20 June 2018Source: Trends in Ecology & EvolutionAuthor(s): Yang Niu, Hang Sun, Martin StevensCamouflage is a key defensive strategy in animals, and it has been used to illustrate and study evolution for 150 years. It is now evident that many camouflage concepts likely also apply to plants, attracting greatly increased attention. Here, we review the hypotheses and evidence for different camouflage strategies used by plants and conceptualise the state of play in plant concealment under a general framework of camouflage theory. In addition, we compare the camouflage strategies used by plants and animals, outline key factors promoting and constraining the evolution of concealment, and highlight the evolutionary and ecological implications of plant camouflage. Ultimately, we show how plant camouflage exhibits many commonalities with animals and how this understudied parallel phenomenon can inform key questions in ecology and evolution.
       
  • Conservation and the Global Infrastructure Tsunami: Disclose, Debate,
           Delay!
    • Abstract: Publication date: Available online 14 June 2018Source: Trends in Ecology & EvolutionAuthor(s): William F. LauranceEfforts to protect nature are facing a growing crisis, one that often revolves around the burgeoning impacts of roads and other infrastructure on biodiversity and ecosystems. Potential solutions are possible but they will involve serious trade-offs and the confrontation of deep misconceptions. Here, I identify some time-critical tactics to aid scientists in informing and influencing the global infrastructure debate.
       
  • An Alternative to Adaptation by Sexual Selection: Habitat Choice
    • Abstract: Publication date: Available online 9 June 2018Source: Trends in Ecology & EvolutionAuthor(s): Cody K. Porter, Christopher K. AkcaliAdaptation in mating signals and preferences has generally been explained by sexual selection. We propose that adaptation in such mating traits might also arise via a non-mutually exclusive process wherein individuals preferentially disperse to habitats where they experience high mating performance. Here we explore the evolutionary implications of this process.

  • Beyond R 0 Maximisation: On Pathogen Evolution and
           Environmental Dimensions
    • Abstract: Publication date: June 2018Source: Trends in Ecology & Evolution, Volume 33, Issue 6Author(s): Sébastien Lion, Johan A.J. MetzA widespread tenet is that evolution of pathogens maximises their basic reproduction ratio, R0. The breakdown of this principle is typically discussed as exception. Here, we argue that a radically different stance is needed, based on evolutionarily stable strategy (ESS) arguments that take account of the ‘dimension of the environmental feedback loop’. The R0 maximisation paradigm requires this feedback loop to be one-dimensional, which notably excludes pathogen diversification. By contrast, almost all realistic ecological ingredients of host–pathogen interactions (density-dependent mortality, multiple infections, limited cross-immunity, multiple transmission routes, host heterogeneity, and spatial structure) will lead to multidimensional feedbacks.
       
  • Climate Velocity Can Inform Conservation in a Warming World
    • Abstract: Publication date: June 2018Source: Trends in Ecology & Evolution, Volume 33, Issue 6Author(s): Isaac Brito-Morales, Jorge García Molinos, David S. Schoeman, Michael T. Burrows, Elvira S. Poloczanska, Christopher J. Brown, Simon Ferrier, Tom D. Harwood, Carissa J. Klein, Eve McDonald-Madden, Pippa J. Moore, John M. Pandolfi, James E.M. Watson, Amelia S. Wenger, Anthony J. RichardsonClimate change is shifting the ranges of species. Simple predictive metrics of range shifts such as climate velocity, that do not require extensive knowledge or data on individual species, could help to guide conservation. We review research on climate velocity, describing the theory underpinning the concept and its assumptions. We highlight how climate velocity has already been applied in conservation-related research, including climate residence time, climate refugia, endemism, historic and projected range shifts, exposure to climate change, and climate connectivity. Finally, we discuss ways to enhance the use of climate velocity in conservation through tailoring it to be more biologically meaningful, informing design of protected areas, conserving ocean biodiversity in 3D, and informing conservation actions.
       
  • Eco-Evolutionary Genomics of Chromosomal Inversions
    • Abstract: Publication date: June 2018Source: Trends in Ecology & Evolution, Volume 33, Issue 6Author(s): Maren Wellenreuther, Louis BernatchezChromosomal inversions have long fascinated evolutionary biologists due to their suppression of recombination, which can protect co-adapted alleles. Emerging research documents that inversions are commonly linked to spectacular phenotypes and have a pervasive role in eco-evolutionary processes, from mating systems, social organisation, environmental adaptation, and reproductive isolation to speciation. Studies also reveal that inversions are taxonomically widespread, with many being old and large, and that balancing selection is commonly facilitating their maintenance. This challenges the traditional view that the role of balancing selection in maintaining variation is relatively minor. The ubiquitous importance of inversions in ecological and evolutionary processes suggests that structural variation should be better acknowledged and integrated in studies pertaining to the molecular basis of adaptation and speciation.
       
  • Games as Tools to Address Conservation Conflicts
    • Abstract: Publication date: June 2018Source: Trends in Ecology & Evolution, Volume 33, Issue 6Author(s): Steve M. Redpath, Aidan Keane, Henrik Andrén, Zachary Baynham-Herd, Nils Bunnefeld, A. Bradley Duthie, Jens Frank, Claude A. Garcia, Johan Månsson, Lovisa Nilsson, Chris R.J. Pollard, O. Sarobidy Rakotonarivo, Carl F. Salk, Henry TraversConservation conflicts represent complex multilayered problems that are challenging to study. We explore the utility of theoretical, experimental, and constructivist approaches to games to help to understand and manage these challenges. We show how these approaches can help to develop theory, understand patterns in conflict, and highlight potentially effective management solutions. The choice of approach should be guided by the research question and by whether the focus is on testing hypotheses, predicting behaviour, or engaging stakeholders. Games provide an exciting opportunity to help to unravel the complexity in conflicts, while researchers need an awareness of the limitations and ethical constraints involved. Given the opportunities, this field will benefit from greater investment and development.
       
  • Is Female Health Cyclical' Evolutionary Perspectives on Menstruation
    • Abstract: Publication date: June 2018Source: Trends in Ecology & Evolution, Volume 33, Issue 6Author(s): Alexandra Alvergne, Vedrana Högqvist TaborWhy do some females menstruate at all' Answering this question has implications for understanding the tight links between reproductive function and organismal immunity. Here we build on the growing evidence that menstruation is the byproduct of a ‘choosy uterus’ to: (i) make the theoretical case for the idea that female immunity is cyclical in menstruating species, (ii) evaluate the evidence for the menstrual modulation of immunity and health in humans, and (iii) speculate on the implications of cyclical female health for female behaviour, male immunity, and host–pathogen interactions. We argue that an understanding of females’ evolved reproductive system is foundational for both tackling the future challenges of the global women’s health agenda and predicting eco-evolutionary dynamics in cyclically reproducing species.
       
  • Trait-Dependent Biogeography: (Re)Integrating Biology into Probabilistic
           Historical Biogeographical Models
    • Abstract: Publication date: June 2018Source: Trends in Ecology & Evolution, Volume 33, Issue 6Author(s): Jeet Sukumaran, L. Lacey KnowlesThe development of process-based probabilistic models for historical biogeography has transformed the field by grounding it in modern statistical hypothesis testing. However, most of these models abstract away biological differences, reducing species to interchangeable lineages. We present here the case for reintegration of biology into probabilistic historical biogeographical models, allowing a broader range of questions about biogeographical processes beyond ancestral range estimation or simple correlation between a trait and a distribution pattern, as well as allowing us to assess how inferences about ancestral ranges themselves might be impacted by differential biological traits. We show how new approaches to inference might cope with the computational challenges resulting from the increased complexity of these trait-based historical biogeographical models.
       
  • Evolutionary Rates Standardized for Evolutionary Space: Perspectives on
           Trait Evolution
    • Abstract: Publication date: June 2018Source: Trends in Ecology & Evolution, Volume 33, Issue 6Author(s): Gregor Rolshausen, T. Jonathan Davies, Andrew P. HendryCharacterization of evolutionary radiations benefits from describing the temporal patterns of trait disparification. Comparative methods attempt this by evaluating the statistical fit of trait distributions to a phylogenetic hypothesis under assumed evolutionary models. However, it can be challenging to differentiate between models, with discriminatory power depending on the modes of evolution underlying trait distributions. We suggest rates of ‘trait space saturation’, standardized for limits to evolutionary change, as an additional tool to distinguish between modes of trait evolution. We evaluate this approach using simulations and show that trait space saturation can identify the true model of trait evolution in cases where traditional comparative methods can fail. We illustrate our approach using diverse empirical studies that represent contrasting scenarios of evolutionary radiation.
       
  • Can Multilayer Networks Advance Animal Behavior Research'
    • Abstract: Publication date: June 2018Source: Trends in Ecology & Evolution, Volume 33, Issue 6Author(s): Matthew J. Silk, Kelly R. Finn, Mason A. Porter, Noa Pinter-WollmanInteractions among individual animals – and between these individuals and their environment – yield complex, multifaceted systems. The development of multilayer network analysis offers a promising new approach for studying animal social behavior and its relation to eco-evolutionary dynamics.
       
  • Illuminating the Evolution of Iridescence
    • Abstract: Publication date: June 2018Source: Trends in Ecology & Evolution, Volume 33, Issue 6Author(s): Thomas E. WhiteIridescence, a change in hue with viewing or illumination geometry, is a common feature of colour patterns in nature, though its significance remains elusive. Recent studies of floral iridescence reveal its functional versatility in enhancing the detection and discrimination of resources by insect viewers, as well as augmenting higher-level processes of memory and perception. Coupled with a known evolutionary lability, these results suggest intriguing possibilities for how this optical curiosity may act as a key to diversification.

    • Abstract: Publication date: Available online 26 May 2018Source: Trends in Ecology & EvolutionAuthor(s): Klara K. Nordén, Trevor D.

Recent studies on birds show how historical reconstructions, the identification of genes affecting color differences, and an increased understanding of the underlying developmental mechanisms are helping to explain why species are the color they are.
       
  • Ecological and Evolutionary Consequences of Parasite Avoidance
    • Abstract: Publication date: Available online 26 May 2018Source: Trends in Ecology & EvolutionAuthor(s): J.C. Buck, S.B. Weinstein, H.S. YoungPredators often cause prey to adopt defensive strategies that reduce predation risk. The ‘ecology of fear’ examines these trait changes and their consequences. Similarly, parasites can cause hosts to adopt defensive strategies that reduce infection risk. However the ecological and evolutionary consequences of these behaviors (the ‘ecology of disgust’) are seldom considered. Here we identify direct and indirect effects of parasite avoidance on hosts and parasites, and examine differences between predators and parasites in terms of cost, detectability, and aggregation. We suggest that the nonconsumptive effects of parasites might overshadow their consumptive effects, as has been shown for predators. We emphasize the value of uniting predator–prey and parasite–host theory under a general consumer–resource framework.
