Biodiversity Dynamics of Neotropical Bat Communities

Neotropical bat communities, comprising over 200 species across multiple families, represent one of the most functionally and taxonomically diverse mammalian assemblages on Earth. These bats perform critical ecosystem services—including pollination of nocturnally flowering plants, seed dispersal in regenerating forests and regulation of insect populations—that underpin the resilience and productivity of tropical ecosystems. Biodiversity dynamics in these communities are shaped by a complex interplay of factors acting at local and landscape scales. Habitat heterogeneity, successional stage and resource phenology drive guild‐specific fluctuations in species composition, while landscape configuration and connectivity influence movement, gene flow and demographic stability. Rapid land‐use change, fragmentation and deforestation impose novel selective pressures, altering functional trait distributions and phylogenetic diversity. Climate variability and extreme weather events further modulate temporal patterns of activity and abundance. Contemporary research integrates taxonomic, functional and phylogenetic metrics to reveal not only shifts in species richness but also changes in ecological roles and evolutionary breadth. These insights inform conservation practice by identifying key habitat elements, spatial scales and restoration pathways needed to maintain ecosystem functions and buffer against emerging threats such as zoonotic spillover and biodiversity loss.

Research from Nature Portfolio

Recent studies have demonstrated that the maturation of secondary forest matrices in fragmented tropical landscapes can substantially enhance the persistence of old-growth specialist bat species. Through a whole-ecosystem fragmentation experiment spanning continuous forest, isolated fragments and regrowing secondary habitats over several decades, researchers observed marked increases in specialist occupancy and abundance as secondary growth aged. In contrast, generalist species showed negligible or even negative responses to matrix regeneration. These findings underscore the conservation potential of allowing secondary forests to mature, providing a natural mechanism to mitigate the negative effects of fragmentation and guide restoration efforts aimed at reinstating specialist-dominated assemblages.

The graph below shows the total number of articles in biodiversity dynamics of neotropical bat communities across all publications each year (not limited to Nature Index journals).

Technical terms

Functional diversity: Variability in ecological roles among species in a community, determined by trait differences such as diet, foraging strategy and morphology.

Phylogenetic richness: Measure of the evolutionary breadth of a community, reflecting the sum of branch lengths in a phylogenetic tree that connect all species present.

Species distribution modelling: Computational approach to predict a species’ geographic range based on environmental variables and occurrence records.

Habitat fragmentation: Process by which continuous habitats are broken into smaller, isolated patches, affecting species movement and community structure.

Secondary forest: Vegetation regrowth following disturbance or clearance of primary forest, often differing in structure and species composition.

Guild: Group of species within a community that exploit similar resources or share functional niches.
