Cross-scale biodiversity patterns and their drivers

We are interested in understanding how and why biodiversity is distributed as it is and how the relative importance of potential drivers (climatic, anthropogenic, etc.) changes across scales in various taxa. Specifically, our research focuses on understanding the processes shaping global, regional and local patterns of taxonomic, functional and phylogenetic diversity. Our ongoing macroecological research is investigating if incorporating metrics of rarity and uniqueness might aid in conservation prioritization. At a regional scale, we are investigating the potential role of climate and habitat structure on biodiversity, using non-invasive monitoring methods such as camera traps and acoustic recorders. We have just launched our Bolivian Sounds project!

At a local scale, we are currently working on two Neotropical urban gradients to test how landscape configuration and urbanization shape bird communities (in Arequipa, Peru) and plant-pollinator interactions (in La Paz).

Community assembly along elevational gradients

Inspired by classic ecological hypotheses, our past and current research aims to test for the relative importance of historical and deterministic contemporary factors shaping montane communities. Using empirical data of birds and trees we collected along elevational gradients and a combination of community ecology, trait-based and phylogenetic approaches with modeling techniques, we examined how species, species traits and communities change across elevations at different scales. Our results provide insights into the factors allowing and maintaining high diversities in mountain systems, informing the conservation of montane biotas. Moving forward, our lab will continue tackling the causes of community and species-level adaptive responses to environmental change across elevations.

Mixed-species flocks of birds

Mixed-species flocks (MSF) are a main social system and a key component of bird diversity across the globe. Surprisingly, they are poorly studied in montane ecosystems. By combining a vast amount of field work with pair-wise and network analyses, our lab investigates (1) the role of facilitation in the composition and structure of MSF and (2) the assembly -and disassembly- of MSF across environmental gradients. A main product of this component was an extensive dataset of mixed-species flocks across the Andes, a dataset with great potential to help future studies. Moving forward, our lab will research if the amount of functional similarities (or differences) among flock mates might affect the potential stability of flocks across space and time.

Natural history of tropical biota

As a lab, we believe in the fundamental role of documenting natural history: the description of patterns through direct observation of the natural world. We resist the current trend to de-emphasize the importance of observation and natural history education in favor of theoretical, or simulation-only research. We make room for both theoretical and computational analyses and the direct description of natural history of our study species and systems.

Collaborations

As a team, we do not work in isolation. We collaborate with and learn from many researchers from across the world, and participate of large collaborative working groups. If you are interested in collaborating, please send me an email at fmontano@lsu.edu
