Urbanisation is a major anthropogenic perturbation presenting novel ecological and evolutionary challenges to wild populations. Symbiotic microorganisms residing in the gastrointestinal tracts (gut) of vertebrates have mutual connections with host physiology respond quickly environmental alterations. However, impact changes urbanisation on gut microbiota remains poorly understood, especially early development. To address this knowledge gap, we characterised juvenile great tits (Parus major) reared artificial nestboxes natural cavities an urban mosaic, employing two distinct frameworks characterising space. Microbial diversity was influenced by cavity type. Alpha affected amount impervious surface surrounding breeding location, positively correlated tree cover density.

Cities pose a major ecological challenge for wildlife worldwide. Phenotypic variation, which can result from underlying genetic variation or plasticity, is an important metric to understand eco-evolutionary responses environmental change. Recent work suggests that urban populations might have higher levels of phenotypic than non-urban counterparts. This prediction, however, has never been tested across species nor over broad geographical range. Here, we conducted meta-analysis the avian literature compare versus means and in phenology (i.e. lay date) reproductive effort clutch size, number fledglings). First, show reproduce earlier smaller broods conspecifics. Second, laying date populations. arises differences between within breeding seasons, conceivably due landscape heterogeneity habitats. These findings reveal novel effect urbanisation on animal life histories with potential implications adaptation environments (which will require further investigation). The birds subjected disturbance could plastic heterogeneous environment, phenology, possibly linked evolutionary potential.

Abstract In the past decade, studies have demonstrated that urban and nonurban wildlife populations exhibit differences in foraging behavior diet.

ABSTRACT The conversion of natural habitats to impervious surfaces in cities affects biotic and abiotic attributes urban ecosystems.

Many studies have documented the average body size of animals declining over time. Compared to mean size, less is known about long-term changes in intraspecific trait variation (ITV), which also important understanding species' ability cope with environmental challenges. On basis 393,499 specimen records from 380 species collected North America between 1880 and 2020, we found that ITV increased by 9.59% for mammals (n = 302) 30.67% birds 78); human-harvested had higher probability increase.
