Urbanization drastically changes environmental conditions, including the introduction of sensory pollutants, such as artificial light at night (ALAN) and anthropogenic noise. To settle in urban habitats, animals need to cope with this new environment. On a short timescale, might pollutants via behavioral adjustments, sexual signaling, which can have important fitness consequences. While ALAN noise generally co-occur habitats are known be able interact modify responses, few studies addressed their combined impact. Our aim was, therefore, assess effects ALAN, noise, interaction on signaling túngara frogs ( Engystomops pustulosus ). We observed calling behavior forest areas, subsequently recorded these laboratory set-up while independently manipulating levels. Frogs areas called higher call rate complexity, was correlated local conditions. Furthermore, our lab experiment revealed that directly alter well combination Exposure alone increased amplitude, whereas interacted lead complexity amplitude. Overall, response patterns consistently showed exposure led more conspicuous signals than expected based additive single pollutants. results support notion population differences partially explained by demonstrating interactive between pollution, study highlights importance examining multisensory instead when trying understand phenotypic divergence urbanized vs. natural areas.

Increasing urbanization has led to large-scale land-use changes, exposing persistent populations drastically altered environments. Sensory pollutants, including low-frequency anthropogenic noise and artificial light at night (ALAN), are typically associated with urban environments known impact animal in a variety of ways. Both ALAN can alter behavioral physiological processes important for survival reproduction, communication circadian rhythms. Although pollution co-occur urbanized areas, few studies have addressed their combined on species' behavior. Here, we assessed how influence spatial temporal variation breeding activity wild frog population. By sites inside tropical rainforest multiple sensory environments, found that both behavior túngara frogs (

Urban areas are characterised by the presence of sensory pollutants, such as anthropogenic noise and artificial light at night (ALAN). Animals can quickly adapt to novel environmental conditions adjusting their behaviour, which is proximately regulated endocrine systems. While responses pollution have been widely reported, this has not often linked changes in hampering understanding adaptiveness responses. Our aim was, therefore, investigate effects urbanisation, specifically urban pollution, on hormone levels male forest túngara frogs (Engystomops pustulosus), a species with reported population divergence behaviour response urbanisation. We quantified testosterone corticosterone release rates field lab before after exposure and/or light. show that differ phenotypes under well conditions. Moreover, led, respectively, an increase decrease corticosterone, whereas pollutants did elicit any response. results modulate populations differentially.

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

Behavioral Ecology, Год журнала: 2024, Номер 35(6)

Опубликована: Окт. 26, 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 non-urban populations have diverged their response. Here, we investigate the effects conditions forest 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 urban-induced also indirectly how females choose potential mates. Our study reveals origin-dependent direct indirect suggests local adaptation populations.

Urbanization transforms natural ecosystems into novel habitats, which can result in negative consequences for biodiversity. Therefore, it is important to understand the mechanisms of maintenance native species urbanized environments, including behavior—which act as a fast response rapid environmental changes. We compared some behavioral traits between two suburban and forest populations Anolis homolechis. Direct observations 779 individuals revealed that perch height was positively influenced by body size, but not sex. Suburban perched higher than ones, even more so afternoon morning; behavior observed forests populations. These differences might be due change from foraging activities morning vigilance, display, and/or thermoregulation afternoon, promoted habitat conditions (e.g., predator abundance, open structure, urban heat). Video recordings 81 focal showed males were active females (i.e., spending less time stationary having display rate), with no significant effect type. As our results diverge previous studies on invasive anoles, we recommend extending comparative non-urban other Anolis.

Population‐level food availability affects postcopulatory sexual selection dynamics in the guppy

Functional Ecology, Год журнала: 2023, Номер 37(10), С. 2748 - 2759

Опубликована: Авг. 7, 2023

Abstract Postcopulatory sexual selection (PCSS), namely sperm competition and cryptic female choice, is typically investigated in benign environments, with a fixed number of partners, which mate at the same time intervals; all conditions that are rarely met natural populations. Although there increasing evidence environmental fluctuations affect before mating, whether to extent they influence postcopulatory trajectories still little explored. PCSS was replicate populations guppies ( Poecilia reticulata ) males females mated after maintained for 2 weeks on either restricted (RE) or ad libitum (AL) diet paternity offspring produced by multiply assigned using microsatellite markers. Compared AL fish, RE (i) had fewer mating but interval between first last not affected; (ii) broods lower variance male fertilization success (a measure opportunity PCSS); (iii) bias towards (reversing precedence observed populations), associated more higher courtship rate. Our results demonstrate short‐term limitation food availability significantly modifying both pattern. Environmental variation should therefore become part research paradigm improve our understanding evolutionary dynamics. Read free Plain Language Summary this article Journal blog.

Molecular Ecology, Год журнала: 2024, Номер 33(17)

Опубликована: Июль 23, 2024

Urbanisation has been increasing worldwide in recent decades, driving environmental change and exerting novel selective pressures on wildlife. Phenotypic differences between urban rural individuals have widely documented several taxa. However, the extent to which urbanisation impacts mating strategies is less known. Here, we investigated extra-pair paternity variation great tits (Parus major) blue (Cyanistes caeruleus) breeding nestboxes set a gradient of Warsaw, Poland, over three seasons. was quantified as amount light pollution, noise impervious surface area (ISA) tree cover within 100-m radius around each nestbox. We obtained genotypes for 1213 at 7344 SNP markers 1299 9366 with genotyping-by-sequencing method, inferred by computing genomewide relatedness matrix. report higher more urbanised areas, example, pollution ISA, lower cover. no such trend found tits. Late-stage survival individual nestlings both species not associated or proxies, thus were able detect fitness benefits drawbacks being an offspring relation urbanisation. Our results contribute growing body knowledge reporting effects avian ecology behaviour, confirm species-specific population-specific patterns variation.
