Abstract Cemeteries are key urban green spaces with multifaceted societal and ecological importance. Their biodiversity is shaped by unique environmental cultural factors. They can potentially protect rare endangered species, yet their conservation value compared other remains largely unexplored. We sought to fill this gap systematically reviewing literature investigate the of cemeteries relative (botanical gardens, institutional premises, natural remnants, parks) comparing species richness proportions native species. analyzed data from 70 papers covering 50 cities in 27 countries linear binomial mixed‐effects models at both site city level. Cemetery was similar parks, except for proportion which parks had significantly higher (21.9% vs. 14.2%, p < 0.001). hosted slightly level than botanical gardens (99.7% 99.6%, 0.001) (96.3% 94.1%, = 0.034) comparable remnants ( > 0.05). also or values premises 0.05) a site‐level In contrast, (slopes −0.11 −0.25, respectively) (4.4% 6.9%, respectively, 0.001 both) were lower areas gardens.

Abstract Nest structure plays a critical role in the reproductive success of birds, varying widely across species and environments. However, evolutionary drivers behind enclosed nests remain unclear, with previous studies yielding inconsistent results. Using global dataset including over 7,400 bird species, this study tests two key hypotheses—protection from predation microclimate regulation—as for evolution nests. Our results show stronger overall support hypothesis, but nest functions can vary by type. Dome are primarily used passerines, especially ground-nesters, to mitigate risks, whereas cavity offer better regulation arid or cold environments both passerine non-passerine species. These findings resolve long-standing debates on nests, reveal potential mechanisms adaptations, valuable insights into how may respond future environmental challenges.

Habitat loss, pollution, and climate change have a global impact on bird diversity, particularly in central Mexico, where human disturbances unplanned urbanization can lead to the decline of this faunal group. In study, effects season (rainy, warm–dry, or cool–dry) environmental variables (size, perimeter, vegetation cover, built distance nearby greenspaces closet natural patch) avian diversity at different sites located peri-urban landscape Metropolitan Area Mexico City were determined. The study was conducted using linear transect method assess composition communities from November 2019 March 2022, recording 290 total species.

Urbanization negatively affects biodiversity worldwide. Consequently, alternative urban development styles are required for an eco-friendlier urbanization process. Thus, two have been suggested: land-sharing (buildings mixed with dispersed green space) and land-sparing interspersed large patches). We assessed differences in species diversity composition of bird assemblages between both Argentinian cities: Santa Fe Buenos Aires. surveyed birds areas during the breeding non-breeding seasons. As a control, we also dominated by impervious surfaces. At local scale, measured environmental noise pedestrian traffic. landscape percent vegetation cover surrounding their distance to main river. In Aires, richness was higher than land-sharing. However, Shannon Simpson were Fe, supported similar diversity. Species varied cities season.
