“…Green spaces are a key element for biodiversity conservation in cities since they represent available habitat for a wide range of organisms (Cornelis and Hermy, 2004;MacGregor-Fors et al, 2016) and much of the research on diversity in urban green spaces has focused on birds (Magle et al, 2012;Beninde et al, 2015). Studies have mainly reported reductions in both the number of species and diversity indices together with compositional changes (Carvajal-Castro et al, 2019;Di Pietro et al, 2020 but see Benitez et al, 2021). Although species richness has been a widely-used measure of biodiversity to assess the effect of urbanization on bird communities (Rush et al, 2014;Canedoli et al, 2017;Matthies et al, 2017) the assumption of species being equivalent may not be ecologically precise (Chave, 2004).…”

“…More specifically, we hypothesized that bird assemblages in the most heavily transformed sites would show a clustered phylogenetic and functional pattern considering that some lineages and traits could be favored by urban areas (Sol et al, 2014;Evans et al, 2018). A third hypothesis was that bird diversity, measured in any of its dimensions, would increase as green space area and habitat heterogeneity increased based on existing information (Matthies et al, 2017;Yang et al, 2020;Benitez et al, 2021).…”

Urban expansion is a pervasive driver of biodiversity loss. To understand the effects of urbanization on diversity, we investigated the response of bird taxonomic, phylogenetic, and functional diversity to urban green spaces’ characteristics in thirty-one green spaces of Mexico City. Selected sites encompassed variation of environmental factors along a transformation gradient, from natural protected areas to landscaped parks. Bird observations were conducted during winter (non-breeding season), spring (dry breeding season), and summer (wet breeding season). We used multi-model inference to assess the relationship of green space area, shape, isolation, tree richness, habitat diversity, and vegetation cover with species richness, Faith’s phylogenetic diversity, and functional richness. We calculated standardized effect sizes from null models to assess phylogenetic and functional structure. We registered 91 species belonging to 28 families across all sites and seasons. The number of detected species was largest in winter and decreased toward the dry breeding season, and then toward the wet breeding season. We found a moderate to strong positive relationship of species richness with phylogenetic diversity and functional richness. Overall, phylogenetic and functional structure of bird communities in green spaces was neither clustered nor over-dispersed. However, few cases of functional clustering, phylogenetic clustering, or both were observed, and they corresponded to natural protected areas. Results showed a predominant role of green space area in determining community diversity and phylogenetic structure while it did not influence functional structure. Contrary to our predictions, habitat diversity had a negative effect on species richness and phylogenetic diversity and this effect was detected only during the wet breeding season, whereas isolation showed a positive relationship with phylogenetic and functional structure, during the wet breeding season and winter, respectively. This study emphasizes the use of complementary measures of diversity together with the comparison between observed and expected values to get a better insight into the mechanisms by which green spaces’ characteristics affect bird diversity across the seasons.

“…Though bird inventories are one of the steps in understanding forest biodiversity, little attention has been given to African avifauna, particularly in sub-Saharan African forests. Preceding studies have demonstrated that forests are vital ecosystems for conserving and protecting avifauna [7,8]. They provide various ecosystem services, including habitats and water for birds [3].…”

“…They provide various ecosystem services, including habitats and water for birds [3]. However, rapid global population growth and rapid development pose a threat to the resilience of natural forest ecosystems and bird species [7,9]. Birds are an acknowledged group of animals that are often used as proxies for other elements of biodiversity [10].…”

The Mbeya range forest reserves (MRFRs) of the southern highland of Tanzania are an important hotspot for biodiversity conservation. However, its avian biodiversity has hardly ever been studied. Thus, for the first time, this study presents the inventory of bird species from MRFRs, demonstrating community structure, functional group, and conservation status. The study was carried out in four forest areas (i.e., Idugumbi, Kawetire, Mount Loleza, and Muvwa) within the MRFRs. The bird survey was carried out monthly between March 2018 and June 2018. Standardised line and point counts, as well as mist netting, were used to collect data. A total of 1052 individual birds, representing 41 species and 22 families, were recorded. Relative abundance, Shannon and Simpson species diversity, and species richness were high in Idugumbi forest and lowest in Kawetire forest. Species diversity differed significantly between the four forest areas. Moreover, Idugumbi and Muvwa had relatively low species composition dissimilarity compared to other forest areas. Different bird functional groups, i.e., insectivores, granivores, nectarivores, carnivores, frugivores, or combinations of these, were recorded in MRFRs. The insectivores were twice as abundant as granivores and nectarivores. The multi–layered vegetation structure of native plants in the Idugumbi forest appears to benefit and contribute to bird communities. The study reveals that MRFRs are an important hotspot for bird species that require ecological monitoring and protection. As a result, appropriate land–use practices near MRFRs should be followed to ensure long–term avian conservation.
