  • A hierarchical multi-scale analysis of the spatial relationship between
           parasitism and host density in urban habitats
    • Authors: María Silvina Fenoglio; Victoria Werenkraut, Juan Manuel Morales, Adriana Salvo
      Abstract: Studies on spatial density dependence in parasitism have paid scarce attention to how changes in host density at different hierarchical scales could influence parasitism in an herbivore at a particular scale. Here, we evaluated if rates of parasitism per leaf (by the whole parasitic complex and by dominant species) of the specialist leaf miner Liriomyza commelinae (Diptera: Agromyzidae) respond to variations in host density at the leaf, plant patch and site levels in an urban setting. We used multi-level Bayesian models that incorporate the spatial hierarchy occurring in this system, as well as habitat factors previously found to have an effect on the L. commelinae parasitoid community in an urban context (patch size, patch isolation and urbanization level). According to the fitted model, overall parasitism rates decreased with increasing number of mines per leaf, being independent of host-density variations at patch and site level. Patch structure was found to have a strong effect on parasitism rates per leaf. The analysis of parasitism by parasitoid species separately showed consistent results with the response at community level. These results suggest that parasitism of the parasitoid community here studied would be sensitive to hierarchical cues related to the host at the leaf level and to the host habitat at the patch level.

  • Variable rainfall has a greater effect than fire on the demography of the
           dominant tree in a semi-arid Eucalyptus savanna
    • Authors: Roderick J. Fensham; Michelle E. Freeman, Boris Laffineur, Harry Macdermott, Lynda D. Prior, Patricia A. Werner
      Abstract: Rainfall, fire and competition are emphasized as determinants of the density and basal area of woody vegetation in savanna. The semi-arid savannas of Australia have substantial multi-year rainfall deficits and insufficient grass fuel to carry annual fire in contrast to the mesic savannas in more northern regions. This study investigates the influence of rainfall deficit and excess, fire and woody competition on the population dynamics of a dominant tree in a semi-arid savanna. All individuals of Eucalyptus melanophloia were mapped and monitored in three, 1-ha plots over an 8.5 year period encompassing wet and dry periods. The plots were unburnt, burnt once and burnt twice. A competition index incorporating the size and distance of neighbours to target individuals was determined. Supplementary studies examined seedling recruitment and the transition of juvenile trees into the sapling layer. Mortality of burnt seedlings was related to lignotuber area but the majority of seedlings are fire resistant within 12 months of germination. Most of the juveniles (≤1 cm dbh) of E. melanophloia either died in the dry period or persisted as juveniles throughout 8.5 years of monitoring. Mortality of juveniles was positively related to woody competition and was higher in the dry period than the wet period. The transition of juveniles to a larger size class occurred at extremely low rates, and a subsidiary study along a clearing boundary suggests release from woody competition allows transition into the sapling layer. From three fires the highest proportion of saplings (1–10 cm dbh) reduced to juveniles was only 5.6% suggesting rates of ‘top-kill’ of E. melanophloia as a result of fire are relatively low. Girth growth was enhanced in wet years, particularly for larger trees (>10 cm dbh), but all trees regardless of size or woody competition levels are vulnerable to drought-induced mortality. Overall the results suggest that variations in rainfall, especially drought-induced mortality, have a much stronger influence on the tree demographics of E. melanophloia in a semi-arid savanna of north-eastern Australia than fire.

  • Effect of species-counting protocols and the spatial distribution of
           effort on rarefaction curves in relation to decision making in
           environmental-impact assessments
    • Authors: Rodrigo Vasconcelos Koblitz; Albertina Pimentel Lima, Marcelo Menin, Diana Pimentel Rojas, Luiz Henrique Condrati, William Ernest Magnusson
      Abstract: Rarefaction Curves are frequently used in Environmental Impact Assessments to evaluate sampling sufficiency, but without clear guidelines of how to ensure that the assumptions of the methods are met. Infrastructure projects in the Brazilian Amazon and elsewhere often occupy extensive areas in remote locations with difficult access, and random sampling under such conditions is impractical. We tested the influence of sampling unit (sample or individual), and geographic distance between samples on rarefaction curve s, and evaluated the magnitude of errors resulting from the misuse of rarefaction curve in decision making, using frogs from four Amazonian sampling sites. Individual-based rarefaction curve were steeper than those generated by sample-based rarefaction curve. Geographic distance influenced the number of exclusive species in a predictable fashion only in one area, and not in the Environmental Impact Assessment site. Misuse of rarefaction curve generated large errors in the identification of vulnerable taxa. Because the rarefaction curve model is sensitive to the assumption of randomness and geographic distance can influence it unpredictably, we suggest that rarefaction curve should generally not be used to estimate sample completeness when making management decisions for environmental licensing purposes.

  • Veligers of the invasive bivalve Limnoperna fortunei in the diet of
           indigenous fish larvae in a eutrophic subtropical reservoir
    • Authors: Esteban M. Paolucci; Valentín Leites, Daniel H. Cataldo, Demetrio Boltovskoy
      Abstract: Larval fish development depends largely on their ability to capture and ingest food items, and on food availability. In this context, invasive species, eutrophication and river impoundments have complex impacts on fish larvae. Using samples collected in 2005–2009 in the Salto Grande reservoir (Argentina–Uruguay), periodically affected by cyanobacterial blooms, we studied the impact of the larvae of the exotic bivalve Limnoperna fortunei (Dunker, 1857) (Bivalvia) on larval fish diets. Compared with other nearby waterbodies, the abundance of fish larvae was scarcer in the reservoir, especially during algal bloom periods. Only 20% of the larval fish with gut contents fed on L. fortunei veligers. Seven fish taxa (of a total of 12) consumed veligers of L. fortunei, but only two showed a preference for this prey. Taxonomic changes in the larval fish assemblages due to the river's impoundment, and temporal uncoupling between veliger densities (affected by the toxigenic effects of Microcystis spp.) and ichthyoplankton could account for the comparatively low trophic importance of the invasive bivalve's veligers. These results reflect the complexity of interactions brought about when the same invasive species invades different environments, underscoring that the impacts involved depend as much on the invader, as on the regional and ecological settings of the area invaded.

  • Ecological consequences of an unusual simultaneous masting of Araucaria
           araucana and Chusquea culeou in North-West Patagonia, Argentina
    • Authors: Fernando A. Milesi; María Laura Guichón, Martín J. Monteverde, Luciana Piudo, Javier Sanguinetti
      Abstract: A simultaneous masting of two abundant species in the temperate forests of North-West Argentinean Patagonia occurred in 2013 for the first time ever recorded: the semelparous bamboo grass Chusquea culeou (colihue), dominating the understory, flowered and set seed across 1100 km2 while pehuén (Araucaria araucana), an endemic conifer co-dominating the tree layer had the highest regionally synchronized mast event in the last 30 years. Strong trophic effects were expected as a consequence of this extraordinary amount of seed, such as rodent outbreaks (ratadas) that followed previous Chusquea spp. mast events and included Oligoryzomys longicaudatus, the main reservoir of the Andes virus causing the Hantavirus Pulmonar Syndrome. From March 2013 to May 2014, we sampled relative abundance and activity of seed-eaters and carnivores at four study sites with different proportions of both masting species. Surprisingly, total rodent capture rates never exceeded 14% in wild habitats and 8% in peridomestic areas showing low overall density in spite of some heavy O. longicaudatus males extending their reproductive activity into winter. Total abundance and relative proportion of granivorous birds peaked at the four sites in winter or spring, when they are usually scarce. Other surveyed organisms (native and exotic seed-eaters, ungulates and carnivores) showed moderate responses at most, probably through aggregation from surrounding areas rather than reproduction. Seed removal from experimental seed stations varied in time and space though never peaked. The clearest pattern of community responses, though much subtler than expected, occurred at the site where colihue was abundant and pehuén scarce. This is the first systematic study that reports such a simultaneous double masting and our surveys revealed no widespread community consequences. We propose that either contingent events, such as an unprecedented drought, or permanent environmental features or contextual characteristics may explain the lack of a rodent outbreak in this area.

  • How do predators and scavengers locate resource hotspots within a tropical
           forest?
    • Authors: Daniel J. D. Natusch; Jessica A. Lyons, Richard Shine
      Abstract: In many parts of the world, wildlife species congregate at ‘hotspot’ locations that offer feeding opportunities unmatched in the wider landscape. But to exploit those resource-rich sites, animals must first locate them. In tropical Australia, predators and scavengers (especially dingos, scrub turkeys, snakes, and invasive toads) gather beneath large canopy-emergent trees that house breeding colonies of metallic starlings (Aplonis metallica). Some wildlife species feed on fallen nestlings whereas others consume the rich insect fauna supported by bird detritus, or the other species attracted to those resources. Those congregations largely cease as soon as colony trees fall, suggesting that wildlife aggregations are responses to bird-associated cues rather than to specific locations. To identify the proximate cues that elicit congregation of wildlife under such trees, we deployed sound cues (starling-chatter) and two types of scent cues (soil from beneath a starling tree, and complete nests on broken branches). We recorded visitations by animals with camera-traps. Starling-chatter did not attract significant numbers of animals, but soil from beneath colony trees attracted many animals (mostly scrub turkeys). Complete nests attracted nest-predators (dingos, snakes). Our experiments suggest that faunal aggregations beneath colony trees are driven by proximate responses to distinctive scent cues in the soil, especially for species that obtain their food from that bird-fertilized substrate; but predators that feed directly on fallen nestlings key in specifically on that resource.

  • Recent invasion of European red foxes (Vulpes vulpes) on to Fraser Island
           (K'gari) and South Stradbroke Island
    • Authors: Benjamin L. Allen; Linda Behrendorff, Lyn Willsher, Janina Kaluza, Jane Oakey
      Abstract: Invasive predators are globally significant drivers of threatened fauna population decline and extinction, and the early detection of new incursions is critical to the chances of successful predator eradication and fauna conservation. Here, we provide evidence of the recent invasion of European red foxes (Vulpes vulpes) on to two large and internationally significant islands off the southeast coast of Queensland, Australia – Fraser Island (K'gari) and South Stradbroke Island. From camera trap footage collected on Fraser Island since 2009, foxes have now been observed on seven different occasions between 2012 and 2016. Two scats collected on South Stradbroke Island in 2013 and 2014 tested positive for fox DNA (and negative for Canis spp. DNA), with fox presence confirmed by subsequent camera trap footage in 2016. These data confirm the recent incursion of foxes on to these islands and suggest that small populations now exist there. Fraser Island and South Stradbroke Island represent key RAMSAR wetland areas of refuge for populations of multiple threatened fauna that have never been previously been exposed to foxes. Fox impacts on these fauna can only be expected to increase without management intervention to eradicate them before they become widespread.

  • How well documented is Australia's flora? Understanding spatial bias in
           vouchered plant specimens
    • Authors: Md. Mohasinul Haque; David A. Nipperess, Rachael V. Gallagher, Linda J. Beaumont
      Abstract: Massive digitization of natural history collections (NHC) has opened the door for researchers to conduct inferential studies on the collection of biological diversity across space and time. The widespread use of NHCs in scientific research makes it essential to characterize potential sources of spatial bias. In this study, we assessed spatial patterns in records from the Australian Virtual Herbarium (AVH), based on >3 000 000 vouchered specimens of around 21 000 native plant species. The AVH is the main database for describing Australia's flora, and identifying its limitations is of paramount interest for the validity of conservation and environmental studies. We characterized how sampling effort is distributed across each Interim Bioregion of Australia (IBRA), then asked: (i) How complete are species inventories for each bioregion? We define completeness (C) as the ratio of observed to estimated species richness, using the Chao 1 estimator, (ii) How is sampling effort related to a commonly used Human Influence Index (HII)? and (iii) What is the probability that additional collections would result in the identification of previously unrecorded species in each bioregion? Sampling effort across bioregions is unequal, which partially reflects the collecting behaviour of naturalists in relation to species richness patterns. The density of records in bioregions ranges from 0.02–8.37 km−2. At the bioregional scale, completeness is generally high with 79% of bioregions estimated to have records for at least 80% of their species. Completeness is partly explained by sampling effort (r = 0.43, p = 0.01), although some bioregions (e.g. Northern Kimberley and Burt Plain) have high completeness yet relatively low sampling effort. The inventory of Hampton, however, is substantially less complete than other bioregions (C = 0.66). Bioregions with high HII consistently have high completeness, while regions with low HII span the full range of completeness values. We calculated that an additional specimen collected from a bioregion has a 0.33% (Wet Tropics) to 11.7% (Arnhem Coast) probability of representing a new species for that region. Our assessment can assist with directing future systematic survey efforts by identifying bioregions where additional surveying may result in the greatest return, in terms of increasing knowledge of species richness and diversity.

  • Population size structure of trees in a semi-arid African savanna: Species
           differ in vulnerability to a changing environment and reintroduction of
           elephants
    • Authors: Timothy Gordon O'Connor; Victoria Lucy Goodall
      Abstract: The size structure of a plant population provides a snapshot of potential population trend and weak inference on past history. Size structure of 24 tree species was sampled in a savanna reserve in order to assess their potential vulnerability to local extirpation following the reintroduction of elephants. Regression of number per size class based on an expected reverse-J structure for a healthy population was undertaken in order to classify trend of each species. On account of the weak realism of this expected structure in semi-arid environments, log-normal mixture models were also fitted to individual observations in order to identify states, whose distribution, size and shape can indicate potential population persistence. Population structure of 12 species approximated a reverse-J, indicating potential future growth. Although regressions of seven species were not significant, suggesting vulnerable populations, mixture models of all except one showed multiple states, indicating variable regeneration and recruitment over time. A single state of adult plants indicates that Sclerocarya birrea was vulnerable to local extirpation if adult mortality escalates. Some apparently declining populations displayed multiple states of established individuals suggesting temporally varying regeneration and recruitment, attributed mainly to rainfall variation, but which were judged as likely to persist. Poor recent regeneration of most species was attributed to well below-average rainfall for the preceding decade. Different savanna tree species apparently ensure persistence based on individualistic responses to population perturbations, but persistence of some following the reintroduction of elephants may be threatened if certain size classes experience escalated mortality. Subsequent monitoring has supported this concern.

  • Environmental and spatial drivers of spider diversity at contrasting
           microhabitats
    • Authors: Philip S. Barton; Maldwyn J. Evans, Claire N. Foster, Saul A. Cunningham, Adrian D. Manning
      Abstract: The relative importance of environmental and spatial drivers of animal diversity varies across scales, but identifying these scales can be difficult if a sampling design does not match the scale of the target organisms' interaction with their habitat. In this study, we quantify and compare the effects of environmental variation and spatial proximity on ground-dwelling spider assemblages sampled from three distinct microhabitat types (open grassland, logs, trees) that recur across structurally heterogeneous grassy woodlands. We used model selection and multivariate procedures to compare the effects of different environmental attributes and spatial proximity on spider assemblages at each microhabitat type. We found that species richness and assemblage composition differed among microhabitat types. Bare ground cover had a negative effect on spider richness under trees, but a positive effect on spider richness in open grassland. Turnover in spider assemblages from open grassland was correlated with environmental distance, but not geographic distance. By contrast, turnover in spiders at logs and trees was correlated with geographic distance, but not environmental distance. Our study suggests that spider assemblages from widespread and connected open grassland habitat were more affected by environmental than spatial gradients, whereas spiders at log and tree habitats were more affected by spatial distance among these discrete but recurring microhabitats. Deliberate selection and sampling of small-scale habitat features can provide robust information about the drivers of arthropod diversity and turnover in landscapes.

  • Extreme specialization to rocky habitats in Tropidurus lizards from
           Brazil: Trade-offs between a fitted ecomorph and autoecology in a harsh
           environment

      Abstract: Ecomorphological theory indicates that different ecological requirements lead to different organismal designs. Given that species with equal requirements could not coexist, traits leading to more efficient use of resources may be selected to avoid competition among closely related syntopic species, generating specialized ecomorphs. We compared habitat use, diet, thermal biology and morphology among the syntopic Tropidurus semitaeniatus, T. helenae and T. hispidus in the Caatinga of Northeastern Brazil. Tropidurus semitaeniatus and T. helenae are flattened lizards specialized to rocks and rock crevices, whereas T. hispidus has a robust body and generalist habits. We aimed to test the hypothesis that morphological modifications observed in the flattened ecomorphs are related to modifications in diet and habitat use. Also, we hypothesized that specialization to habitat induces morphological modifications, which in turn may constrain lizard performance. Flattened species differed in habitat use, morphology and prey size when compared with the generalist ecomorph. Morphological modifications were related to specializations to rocky habitats and constrained the variety of prey items consumed. This phenotype also reduced their reproductive output when compared with a robust, generalist ecomorph.

  • Establishment of native grasses and their impact on exotic annuals in
           degraded box gum woodlands
    • Authors: Ian Cole; Suzanne Prober, Ian Lunt, Terry Koen
      Abstract: Restoration goals often involve the addition of new species to resident, degraded communities but in box gum woodlands such restoration is often constrained by competition from persistent exotic annuals that control critical ecological processes. Nutrient reduction (via carbon addition) and seed bank depletion are two approaches to reduce competition from exotic annuals but to be effective these treatments must allow establishment of species such as native grasses. This experiment was conducted in two degraded Austrostipa understoreys in the box gum woodlands of south-east Australia. It compares the effects of carbon addition (sugar), seed depletion (spring burning or spring grazing) and combinations of carbon addition and seed depletion treatments on the establishment of C3 and C4 native grasses, and measured the effects of their establishment on soil nitrate concentration and exotic annuals. Treatments that reduced exotic annual abundance did not increase initial germination of the C4 native grasses, Bothriochloa or Themeda. However, sugar increased seedling survival of Themeda and Bothriochloa and grazing increased seedling survival of Bothriochloa, presumably by reducing effects of exotic annuals. Poa and Rytidosperma (C3 native grasses) failed to establish. Although we were unable to detect any reduction in soil nitrate concentration, swards with successful recruitment of C4 grasses suppressed exotic annuals more than the Austrostipa-only swards at one site (the other was affected by wildfire). Further, Austrostipa-Themeda swards were more effective than Austrostipa-Bothriochloa for suppressing exotics, pointing to a role for both functional and species identity in the degree of resistance conferred.

  • Changes in the realized niche of the invasive succulent CAM plant Furcraea
           foetida
    • Authors: Cristiana Barbosa; Juan Manuel Otalora, Eduardo L. H. Giehl, Fabricio Villalobos, Rafael Loyola, Geiziane Tessarolo, Nathália Machado, Tânia Tarabini Castellani
      Abstract: Furcraea foetida (Asparagaceae) is a native plant of Central America and northern South America but there is no information about its country of origin. The species was introduced into Brazil and is now considered invasive, particularly in coastal ecosystems. To date, nothing is known about the environmental factors that constrain its distribution and there is only inconclusive information about its location of origin. We used reciprocal distribution models (RDM) to assess invasion risk of F. foetida across Brazil and to identify source regions in its native range. We also tested the niche conservatism hypothesis using Principal Components Analyses and statistical tests of niche equivalency and similarity between its native and invaded ranges. For RDM analysis, we built two models using maximum entropy, one using records in the native range to predict the invaded distribution (forward-Ecological Niche Model or forward-ENM) and one using records in the invaded range to predict the native distribution (reverse-ENM). Forward-ENM indicated invasion risk in the Cerrado region and the innermost region of the Atlantic Forest, however, failed to predict the current occurrence in southern Brazil. Reverse-ENM supported an existing hypothesis that F. foetida originated in the Orinoco river basin, Amazon basin and Caribbean islands. Prediction errors in the RDM and multivariate analysis indicated that the species expanded its realized niche in Brazil. The niche similarity test further suggested that the niche differences are because of differences in habitat availability between the two ranges, not because of evolutionary changes. We hypothesize that physiological pre-adaptation (especially, the crassulacean acid metabolism), human-driven propagule pressure and high competitive ability are the main factors determining the current spatial distribution of the species in Brazil. Our study highlights the need to include F. foetida in plant invasion monitoring programs, especially in priority conservation areas where the species has still not been introduced.

  • Patterns of storage tissue and starch distribution in the young taproot of
           obligate seeders and resprouters of Australian Proteaceae (Juss.):
           Possible evidence of homoplastic evolution
    • Authors: Barbara J. Bowen; John S. Pate
      Abstract: The ancient Gondwanan family Proteaceae has its greatest speciation in fire-prone environments of Australia. Fire response is either by seedling recruitment from parent plants that succumb to fire (obligate seeders), or survival and resprouting from protected buds (resprouters). Starch is the main source of energy for resprouting and in roots is restricted to parenchyma tissue. This study compared the size and distribution of storage parenchyma and the magnitude of starch reserves in roots of several proteaceous species from different genera in relation to their fire response and taxonomy. Cross-sections (2 μm) of roots of 51 resprouter and 42 seeder species from 12 genera were stained for starch. Areas of cortex and ray parenchyma along with starch grain density were measured using image analysis software (Assess 2.0) and comparable samples of root tissue were assayed chemically for starch. Starch, where present, predominated in ray and cortex tissue with a greater percentage in resprouters (13.4 ± 1.03) than seeders (1.8 ± 0.26); these results correlated significantly with the chemical assay for starch (r = 0.93, P

  • Sampling grain influences trends in vegetation composition and diversity
           with time since fire in Australian heathland
    • Authors: Timothy J. Wills; Jennifer Read
      Abstract: Scale-dependency of pattern and process is well-understood for many ecological communities; however, the influence of spatial scale (sampling grain) in detecting temporal change in communities is less well-understood. The temperate lowland heathlands of south-east Australia are one of the most fire-prone ecosystems on earth. Despite the extensive literature documenting the effect of time since fire on heathlands, we know little about how sampling grain influences trends in vegetation variables over time, and whether these trends are scale-dependent. Using 3500 ha of heathland in the Gippsland Lakes Coastal Park, south-east Australia, we investigated how above-ground species composition and diversity, and trends in these variables with increasing time since fire, were influenced by sampling grain (1 m2, 10 m2, 100 m2, 900 m2, 1 ha, 4 ha). Sampling grain influenced patterns detected in vegetation variables and in some instances, significantly affected their relationship with time since fire. Richness decreased with time since fire, with mean richness decreasing at three of the four grains, while total richness decreased at half of the sampled grains. Evenness (J) decreased with increasing time since fire for all grains except 1 m2. The decline in diversity (H) with time since fire appeared to be independent of scale, as all grains decreased significantly with increasing time since fire. Community heterogeneity demonstrated a weak response to time since fire across most grains. Changes in composition among young (0–6 years since fire), intermediate (9–19 years) and old (23–27 years) sites were dependent on sampling grain, with all grains exhibiting significant differences in composition, apart from the 1 m2 grain and the 100 m2 grain (presence/absence data). Overall, species composition, richness, evenness, diversity and community heterogeneity were dependent on the scale at which the vegetation was sampled. In addition, trends in many of these vegetation variables with increasing time since fire were scale-dependent. This work provides strong evidence that sampling at multiple grains contributes substantially to understanding pattern and process in heathlands.

  • Growing faster and colonizing first: Evolutionary and ecological
           advantages of the tallest individuals within a cohort
    • Authors: Natashi A. L. Pilon; Giselda Durigan
      Abstract: The transition between ontogenetic stages, from juvenile to reproductive adult, is an important moment in the life history of individuals in a plant population, since the persistence of their genes depends on it. The size of an individual is recognized as a predictor for this transition, but little is known about what determines the minimum size to become a reproductive adult, or if a higher growth rate can anticipate or not that transition. In addition, the relationship between size and ontogeny have not yet been studied for woody species. To verify whether the change in ontogenetic stage in woody plants is dependent on plant size, we followed the development of even-aged cultivated seedlings of 53 native species of the Brazilian savanna, Assis State Forest, State of São Paulo, up to their first reproductive event. In 83% of the species the tallest individual – the fastest growing in height – was the first to bloom. Our results support previous studies that consider plant size as one of the most important factors driving certain demographic processes, and allow inferences about the importance of size and growth rate on plant fitness and community assembly. Individuals with higher growth rates during the juvenile stage are the first to reach maturity. Consequently, among individuals of the same cohort, those growing faster will take ecological and evolutionary advantage since they can reproduce precociously and leave descendants prior to their smaller conspecifics, increasing the expression of their genes in the community. It is therefore expected that, along the evolutionary scale, growth rate of Brazilian savanna woody species should continuously increase.

  • Local habitat complexity correlates with song complexity in a vocally
           elaborate honeyeater
    • Authors: Samuel D. Hill; Matthew D. M. Pawley, Weihong Ji
      Abstract: Song complexity is an important behavioural trait in songbirds, subject to sexual selection. Elucidation of intraspecific variation in song complexity can provide insights into its evolution. In this study, we investigated song complexity variation in tūī (Prosthemadera novaeseelandiae), a vocally complex songbird endemic to New Zealand. At two separate nature reserves, we recorded male songs in two habitat types: forest remnants with high habitat complexity, and open habitats with lower habitat complexity. Analyses indicated strong evidence that song complexity was higher in forest habitats. Possible explanations for this divergence include: (i) competition between individuals results in higher quality, dominant males with more complex songs occupying forest habitats, and less competitive males occupying open habitat zones; (ii) forest habitats provide more abundant resources therefore higher tūī density, resulting in more complex songs; and (iii) a higher abundance of food in dense forest habitats may reduce nutritional stress during development resulting in full development of song nuclei. However, these hypotheses on the drivers of habitat effects on tūī song complexity remain to be tested.
