Spatial Structuring of Biodiversity

A comprehensive review of diversity congruence in community ecology

An ongoing systematic review on ecological studies that measured more than one component of diversity (taxonomic, phylogenetic, functional). This project is being done in collaboration with Dr. Marten Winter, Esra Elfaki, Matthias Grenié, Alexander Ordynets, Cátia Lúcio Pereira, and Stefan Pinkert. This project was led by myself and Dr. Marten Winter at the iDiv 2016 Summer  School held in June 2016.

Spatial scaling of multi-component nonvolant mammal diversity in Madagascar and Australia.

Community assembly is dependent upon diversity type (taxonomic, functional, or phylogenetic) and spatial scale.

In my PhD I investigated the processes shaping the diversity of primate and nonvolant mammal communities using taxonomic, functional and phylogenetic diversity measures and a spatially explicit modelling approach. I described mammal diversity patterns at ecoregional, regional, and inter-regional scales within and across Madagascar and Australia. Phylogenetic and functional diversity measures were weakly correlated, and phylogenetic diversity provided assembly models with weak explanatory power. Environmental and spatial variables indicating the combined operation of environmental sorting and dispersal limitation variably shaped the taxonomic and functional diversity of mammal communities in Madagascar and Australia. Mammal community diversity was regionally specific, shaped by the unique historical and landscape components of each region, including ecoregional effects and the extinction of sympatric species. Macroscale studies of diversity should carefully investigate the influence of spatial scale and regional factors that can result in varied assembly patterns and unique ecological communities, such as those present for the nonvolant mammals of Madagascar and Australia.
