Bird color and taxonomic diversity are negatively related to human disturbance in urban parks

Web Ecology, Journal Year: 2024, Volume and Issue: 24(1), P. 1 - 10

Published: Feb. 5, 2024

Abstract. Recently, studies have shown that highly urbanized areas are numerically dominated by birds with grey plumage, probably favoring camouflage impervious surfaces. However, patterns of bird color diversity in urban green remain unexplored. In parks, sites surrounded may be species, whereas parks pedestrians feed favor commensal which also plumage. Thus, we explore the relationship between environmental variables and taxonomic parks. Bird surveys were conducted twice fixed points six cities central Argentina. was assessed characterizing plumage coloration different parts body presence sexual dimorphism, polymorphism, iridescence. Then, richness (abundance-based) calculated species mean pairwise distance. Null models used to quantify richness-corrected diversity. increased green-area size, decreased increasing pedestrian traffic.

Therefore, increase mediated increases richness. clustered highest human disturbance, took advantage food discarded humans.

Bird‐mediated ecosystem services and disservices in cities and towns

Frontiers in Ecology and the Environment, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 10, 2025

All cities are home to birds, which, through their activities, can either enhance or detract from human well‐being. To identify such interactions, we synthesize current understanding of bird‐mediated ecosystem services and disservices in cities. We find widespread evidence that birds provide cultural services, but the link between urban bird diversity these benefits is surprisingly tenuous. Birds also have potential regulating services; however, rather than being measured, usually assumed non‐urban research, may be overestimated (eg pollination, seed dispersal) undervalued (decomposition, nutrient cycling). People's perceptions not uniform, always delivered equitably among residents. call for moving beyond using species richness traits as proxies, instead explicitly measuring across heterogeneous landscape. Such information critical designing sustain biodiversity result net positive, equitable, people.

Noise Pollution and Urban Birds Breeding in the Center of the Iberian Peninsula: Effects on Diversity and Abundance

Diversity, Journal Year: 2025, Volume and Issue: 17(5), P. 338 - 338

Published: May 8, 2025

In an increasingly urbanized world, biodiversity, and more specifically, birdlife located in ecosystems, faces several threats. Among these, noise pollution has proven to be one of the most significant, as it affects effectiveness efficiency acoustic communication. We studied relationship between diversity abundance birds breeding urban areas central region Iberian Peninsula (Spain). analyzed how species density varied across three levels (high, medium, low). Species decreased with high compared sites medium low noise. frequent found within each category. identified eight additional noise-tolerant whose had significantly increased environments (e.g., Blackbird, Eurasian Tree Sparrow, Coal Tit). The ten sensitive species, such Common Linnet, House European Greenfinch, densities when level increased. Identifying sensitivity (the effect) bird is vital for effective conservation management measures sustainable planning cities.

Crumb bums? Context dependence in ecosystem services supplied by common urban animals

Abstract Bolstering the supply of animal‐mediated ecosystem services is an emerging priority in human‐altered landscapes. Such are driven not only by environmental factors that shape communities species provide service but also ecological context affects behavior these species. In this study, we used a field experiment to investigate depends on resource use behavior—the removal littered food waste birds and squirrels urban green spaces. We first explore how landscape‐scale urbanization composition litter‐removing community. then examine two facets provisioning—the amount removed speed removal—and they vary across contexts represented space type (picnic areas, parks, forest preserves), bird squirrel abundance, number people, existing litter, weather conditions. found although affected within spaces, provisioning was context‐dependent. Littered were provided at higher rates park picnic sites than preserves abundance eastern gray ( Sciurus carolinensis ) main driver services. Where abundant, more removed, began completed quickly. When accounted for, from areas sites, indicating dependence likely behavioral responses ambient levels habitats. This study highlights role common providing valuable importance its supply. Efforts account for landscapes should address potential be single context‐dependent influence behavior.

Variation in forest patch habitat quality for white‐footed mice driven by invasive plants in an urbanizing landscape

Abstract The habitat quality of urban forest patches is determined by the composition and structure vegetation which in turn affects trophic resources shelter provided for wildlife species. In addition, development landscape surrounding can affect species' movement between patches, further influencing quality. Understanding how species respond to variation among especially important that contribute ecosystem services disservices residents. Here, we assessed white‐footed mice ( Peromyscus leucopus ) because they are one key reservoir Lyme disease influence dilution mammal communities. We examined across a gradient landscape‐scale around Philadelphia, PA, USA. particular, focused on shifts associated with invasive understory shrubs given their prevalence our study system. then quantified numerical (index relative abundance) morphological responses While observed no significant effects environmental variables index mouse abundance were morphology. Most notably, larger at sites more shrub This indicates may be creating higher‐quality mice. Because larger‐bodied likely feed ticks, this result has implications dynamics areas, such as amplified transmission.
