Environmental heterogeneity is considered as one of the main drivers of habitat specialization and niche evolution among tropical plant lineages, and local scale habitat specialization promotes niche differentiation among sister taxa. In this study, we examined the degree to which habitat specialization lead to niche differentiation across the distribution range of a given species using five species of the family Myristicaceae native to Western Ghats, India as an example. In the Western Ghats, Myristicaceae species...

Functional diversity of farmland bees across rural-urban landscapes in a tropical megacity

Urbanization is a major threat to biodiversity and food security, as expanding cities, especially in the Global South, increasingly compete with natural and agricultural lands. However, the impact of urban expansion on agricultural biodiversity in tropical regions is overlooked. Here we assessed how urbanization affects the functional response of farmland bees, the most important pollinators for crop production. We sampled bees across three seasons in 36 conventional vegetable-producing farms spread along an urbanization gradient in...

Taxonomic and functional homogenization of farmland birds along an urbanization gradient in a tropical megacity

Gabriel Marcacci, Catrin Westphal, Arne Wenzel, Varsha Raj, Nils Nölke, Teja Tscharntke & Ingo Graß
Urbanization is a major driver of land use change and biodiversity decline. While most of the ongoing and future urbanization hot spots are located in the Global South, the impact of urban expansion on agricultural biodiversity and associated functions and services in these regions has widely been neglected. Additionally, most studies assess biodiversity responses at local scale (α-diversity), however, ecosystem functioning is strongly determined by compositional and functional turnover of communities (β-diversity) at regional scales....
