Abstract The island syndrome is a widespread biological phenomenon that describes suite of morphological, behavioural, demographic and life‐history changes associated with dwelling. These similar evolutionary responses among disparate groups animals plants represent remarkable case convergent evolution. Among animals, birds are highly suitable group to study the syndrome; they comparatively data‐rich taxon, frequent colonisers, sometimes display extreme adaptations such as loss flight. However, avian literature fragmented, multiple components rarely considered together even though many inextricably linked. We reviewed multi‐species comparative studies, single‐species or population‐level studies anecdotal accounts, summarise assess support for individual birds, identify suites traits should be together. weight evidence patterns in morphology substantial, but more partial various aspects behaviour, life history physiology. Full validation will require less‐studied treated framework, covarying examined an integrated way. An improved description scope pave way understanding its drivers.

Species groups of Western Hemispheric Onthophagus Latreille (Coleoptera: Scarabaeidae: Scarabaeinae: Onthophagini) are suggested using COI barcoding and gene trees supported by congruence with external morphology, behavior, ecology, biogeographic evidence. New species groups, complexes, taxonomic statuses offered, other preexisting proposals confirmed. No gap w as found between the intragroup intergroup genetic distance blocks, but average (8.38%) (13.88%) Kimura-two-parameter distances statistically different. The following seven were mtDNA barcode analysis independent evidence: O. chevrolati, clypeatus, dicranius, gazellinus, hircus, landolti, mexicanus. Eight new suggested: crinitus, curvicornis, eulophus, hecate, hoepfneri, marginatus, nasutus, velutinus. Possible behavioral/ecological adaptations morphological characters also discussed. evolutionary hypotheses advanced. An identification key for is presented.

Island tameness results largely from a lack of natural predators. Because some insular rattlesnake populations functional rattles, presumably the consequence relaxed selection reduced predation, we hypothesized that Santa Catalina Island, California, USA, population southern Pacific (Crotalus helleri, which possesses rattle), would exhibit decrement in defensive behavior relative to their mainland counterparts. Contrary our prediction, rattlesnakes island not only lacked compared snakes, but instead exhibited measurably greater levels defensiveness. snakes attempted bite 4.7 times more frequently as endeavored secure them by hand, and required 2.1-fold time be pinned captured. When induced beaker after being grasped, also delivered quantities venom when controlling for body size. The additional resulted larger pulses ejected fangs. We found no effects duration captivity (2–36 months), suggests an absence long-term habituation antipredator behaviors. Breeding bird surveys Christmas counts indicated densities avian predators on mainland. However, historical estimates confirmed foxes introduced mammalian (cats pigs) antagonists (herbivorous ungulates) substantially exceeded those recent centuries, therefore best explain paradoxically exaggerated behaviors Catalina’s rattlesnakes. These findings augment understanding anthropogenic animals underscore how these can negatively affect human safety.

Anthropogenic activities are causing a steep decline of wildlife populations. Increased inbreeding in shrinking populations can substantially curb individual fitness and population viability. One potentially important but largely ignored component depression may be cognitive decline. Cognition affects an animal's capacity to respond environmental disturbance, which, the face global change, make difference between persistence extinction. While effects on performance have been relatively well documented humans, they remain unexplored natural Here we review current (limited) knowledge whether how impinges animals' abilities. Insights into relationship cognition could prove valuable not only for comprehending development evolution also conservation.

Experimental approaches to measure territory defence can be used interpret the relative magnitude of intraspecific aggression in different ecological contexts. The aim this study is examine response Fijian forest bird species conspecific intruders using playback previously recorded songs along an elevational gradient. We address two questions: Do foraging guilds Fiji's birds show patterns territorial behaviour towards intruders? Secondly, do stronger at higher elevations? explore these questions across (insectivore and omnivore) on Viti Levu Island, Fiji. All four focal had a highest elevation, endemic insectivore strongest response. Perhaps high elevation insects are less abundant hence increased aggressiveness favoured defend territory, and/or perhaps general more aggressive colonise areas, both ideas that require further testing. This provides first insights into conspecifics explored relation avian also context human activity, disturbance threats persistence gradients.

Abstract Studies of the effects insularity on animal signals are scarce, particularly in lizards. Here, we use Lilford’s wall lizard from Dragonera (Podarcis lilfordi gigliolii) to ask how island conditions have affected its repertoire social signals, focusing two visual shared by many Podarcis species: ultraviolet (UV)–blue-reflecting ventrolateral colour patches and displays. We examined whether number or spectral characteristics UV–blue associated with traits related individual quality. also used models assess conspicuousness measure sexual dichromatism. did not observe foot shakes any other displays usually found continental Podarcis. that none patch variables covaried morphometric indicative fighting ability body condition males, suggesting this coloration does signal very little In particular, females seem over-expressed more similar those males than Ancestral state reconstruction reveals lack dimorphism is a derived for P. gigliolii living small islands. Our results thus show pattern reduced signalling relative mainland Podarcis, some being lost under-expressed (visual displays) others losing their function (UV–blue patches). hypothesize these changes attributable high population density gigliolii, which discourages territorial behaviour promotes extreme tolerance, making most unnecessary.
