Abstract With novel human–wildlife interaction, predation regimes, and environmental conditions, in addition to often fragmented smaller populations, urban areas present wildlife with altered natural selection parameters genetic drift potential compared nonurban regions. Plumage pelage coloration birds mammals has evolved as a balance between avoiding detection by predator or prey, sexual selection, thermoregulation. However, mutation rates, reduced risk, increased temperatures, strong drift, interaction people, the evolutionary contexts which these colorations arose are radically different from what is areas. Regionally alternative color morphs leucistic melanistic individuals that aren't typical of most avian mammalian populations may become more frequent result adaptive neutral evolution. Therefore, I conceptualize that, areas, conspicuous morphologies persist, leading an increase frequency regionally atypical coloration.

ABSTRACT Brilliant, diverse colour ornaments of birds were one the crucial cues that led Darwin to idea sexual selection. Although avian colouration plays many functions, including concealment, thermoregulation, or advertisement as a distasteful prey, quality‐signalling role in selection has attracted most research attention. Sexually selected are thought be more susceptible external stressors than naturally traits, and such, they might used test for environmental quality. For this reason, last two decades have seen numerous studies on impact anthropogenic pollution expression various traits. Herein, we provide first meta‐analytical summary these results examine whether there is an interaction between mechanism production (carotenoid‐based, melanin‐based structural) type factor (categorised heavy metals, persistent organic pollutants, urbanisation, other). Following assumption heightened condition dependence under selection, also expected magnitude effect sizes higher males. The overall size was close significance negative, supporting general detrimental pollutants colouration. In contrast expectations, no types colour‐producing mechanisms. Yet significant differences sensitivity mechanisms, with carotenoid‐based being affected by disturbances. Moreover, observed tendency towards We identified publication gap structural colouration, which, compared pigment‐based remains markedly understudied should thus prioritised future research. Finally, call unification methods quantification ecological ensure comparability among studies.

Effects of Urbanization on Ventral Patch Size and Phenotypic Correlates of Patch Expression in Male Western Fence Lizards (Sceloporus occidentalis)

Ecology and Evolution, Год журнала: 2025, Номер 15(2)

Опубликована: Янв. 28, 2025

ABSTRACT In some animals, males use colorful ornaments or badges to visually communicate with conspecifics. These traits can be condition‐dependent, suggesting that environmental changes could impact the intensity of male sexual signals. Drastic habitat caused by urbanization act as physiological stressors, potentially affecting signaling through condition immune function. Here, we quantified effects on ventral patch size and correlates expression, namely body size, condition, corticosterone concentrations, ectoparasites in Western Fence Lizards ( Sceloporus occidentalis ). We compared three aspects color patches between urban natural populations: area throat patch, total paired belly patches, black borders patches. All measurements across both types were positively related was indicating these may signal competitive ability and/or quality. Males from populations had larger than those after controlling for size. This difference associated a probability ectoparasite infection, but not differences concentrations populations. Our results indicate an effect function although this idea remains untested. Overall, show traits, which have repercussions visual communication environments.

Colourful Urban Birds: Bird Species Successful in Urban Environments Have More Elaborate Colours and Less Brown

Ecology Letters, Год журнала: 2025, Номер 28(4)

Опубликована: Апрель 1, 2025

Rapidly expanding urbanisation presents significant challenges to wildlife. Consequently, many studies have investigated the impact of on diverse organisms. However, despite ecological relevance animal colouration, its association with remains poorly understood. Using a global database, we computed an index urban success for 1287 bird species and quantified estimates plumage colour. Our analyses showed that birds do well in environments are more likely be blue, dark grey black, less brown or yellow. After considering phylogenetic relatedness, only effects yellow remained significant. Species high also exhibit elaborate colours, but not higher sexual dichromatism. We provide eco-evolutionary explanations these results. Assemblage-level did support colour homogenisation hypothesis: Urban communities were colour-diverse after accounting richness. findings suggest colours part urban-associated syndrome.

Abstract Traffic noise is one of the selection pressures urban habitats. Because interferes with acoustic communication, many studies have shown that temporal structures signals change depending on noise. However, it often unknown whether changes are adaptive, such as being more easily located by females under noisy conditions. To investigate phenomena, bend-legged ground crickets (Dianemobius nigrofasciatus) were collected from three and rural habitats reared in a common garden Male calling songs female mate location behaviour progeny measured. Urban males emitted song higher dominant frequency shorter chirp than did males. The playback experiment response localization to males, controlling for noise, showed there no significant effects between Although elicited faster females, effect was limited. These results indicate not adaptive terms choice. quickly suggest mating occur

Abstract Research on urban noises affecting acoustic communication of animals is a growing area study and conservation concern. However, the consequences aircraft noise anuran have been explored restricted basis to date. In this study, we investigated impact overflights individual chorus performance signalling in Pedregal frog ( Eleutherodactylus grandis ), microendemic threatened species from Mexico City. During summer 2021, recorded signals male individuals conducted monitoring analyse how social interactions change due overflights. For purpose, evaluated properties call, including call duration, dominant frequency, amplitude, repetition rate. Additionally, measured amplitude environmental by means two types complementary methodological approaches. Our results show changes with longer lower higher overflights, while rate did not vary. Furthermore, decrease number calls within was observed during overflight. Overall, these that causes plastic between conspecifics decrease, thus adding new disturbance already suffers other anthropogenic noises, habitat fragmentation.

Urban sensory conditions alter rival interactions and mate choice in urban and forest túngara frogs

bioRxiv (Cold Spring Harbor Laboratory), Год журнала: 2024, Номер unknown

Опубликована: Янв. 15, 2024

Abstract Sexual communication often takes place in networks with multiple competing signalers being simultaneously assessed by mate choosers. Altered sensory conditions, such as noise and light pollution, can affect altering signal production perception. While evidence of pollution affecting sexual signaling is widespread, few studies assess impacts on during rival interactions well choice, let alone whether urban forest populations have diverged their response. Here, we investigate the effects conditions túngara frogs ( Engystomops pustulosus ). We recorded dyadic vocal choice without lab. show that directly impact intensity interactions, differences between rivals though changes were opposite directions for origins. Moreover, demonstrate response to also indirectly how females choose potential mates. Our study reveals origin-dependent direct indirect which ultimately translate into fitness consequences populations.
