Interactive and independent effects of light and noise pollution on sexual signaling in frogs

Frontiers in Ecology and Evolution, Journal Year: 2022, Volume and Issue: 10

Published: Aug. 15, 2022

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.

Anthropogenic noise and light alter temporal but not spatial breeding behavior in a wild frog

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.

A multidimensional framework to quantify the effects of urbanization on avian breeding fitness

Ecology and Evolution, Journal Year: 2023, Volume and Issue: 13(7)

Published: July 1, 2023

Abstract Urbanization has dramatically altered Earth's landscapes and changed a multitude of environmental factors. This resulted in intense land‐use change, adverse consequences such as the urban heat island effect (UHI), noise pollution, artificial light at night (ALAN). However, there is lack research on combined effects these factors life‐history traits fitness, how interactions shape food resources drive patterns species persistence. Here, we systematically reviewed literature created comprehensive framework mechanistic pathways by which urbanization affects fitness thus favors certain species. We found that urbanization‐induced changes vegetation, habitat quality, spring temperature, resource availability, acoustic environment, nighttime light, behaviors (e.g., laying, foraging, communicating) influence breeding choices, optimal time windows reduce phenological mismatch, success. Insectivorous omnivorous are especially sensitive to temperature often experience advanced laying smaller clutch sizes areas. By contrast, some granivorous little difference size number fledglings because areas make it easier access anthropogenic avoid predation. Furthermore, interactive change UHI could be synergistic locations where loss fragmentation greatest when extreme‐hot weather events take place instances, may mitigate impact local scales provide suitable conditions shifting environment more favorable for species' thermal limits extending window available As result, determined five broad directions further highlight provides great opportunity study filtering processes population dynamics.

Do seabirds dream of artificial lights? Understanding light preferences of Procellariiformes

ABSTRACT Seabirds, and particularly fledglings of burrow-nesting species, are greatly impacted by light pollution. During their inaugural flights from colony to sea, become grounded after encountering artificial light. Such groundings, or fallout events, affect many each year. To mitigate this induced mortality, rescue programs have been implemented for decades in locations worldwide. Despite the notoriety fallouts, contributing behavioural biological factors remain mostly unknown. How do mechanisms attraction avoidance interact how they manifest different groups (e.g., age, personality, populations), pollution levels, open questions. We tested preferences Cory’s shearwater Calonectris borealis fledglings, rescued being urban areas, breeding adults, contrasting sources.

Noise pollution can degrade the behavioral, physiological, and psychological health of humans other creatures. We used breeding pairs Eastern Bluebirds (Sialia sialis) to assess behavioral reproductive responses both chronic roadway noise experimental intermittent playbacks construction noise. Active nests in boxes placed near far from large roads were randomly assigned as treatments or controls for during incubation. Using temperature signatures iButtons within nest cups we quantified certain female incubation behaviors (# length bouts, # small fluctuations, total warming minutes per day) hatching success was recorded 40 spring 2019. Nests quiet areas that received no additional playback had markedly higher than any exposed traffic only, 3–4 days lowest success. Females traffic-quiet increased restlessness (small fluctuations) experienced decreasing number increased. Thus, birds choosing either noisy contrasting bouts Other could detect unaffected by but changed expected ways with seasonal progression. In sum, types decrease hatch rate, this is likely due restlessness, too many drops maintain optimal embryo development.

ABSTRACT Chronic traffic noise is increasingly recognised as a potential hazard to wildlife. Several songbird species have been shown breed poorly in exposed habitats. However, identifying whether causal this requires experimental approaches. We tested exposure chronic affected parental behaviour and reproductive success zebra finches (Taeniopygia guttata).
