Dr. Ahmed El-Gabbas

I am conservation & quantitative ecologist interested in modelling the spatio-temporal distribution of species. My research is mainly focused on studying the spatial distribution of biodiversity and the prioritization of conservation efforts. I am interested in understanding factors determining species distributions in time and space, mainly using the overarching methods of species distribution modelling. Currently, I am modelling the spatio-temporal distribution of baleen whales in the Southern Ocean using visual observations and passive acoustic data.

I am a biologist and ecologist with a doctorate in environmental sciences specialized in ecoacoustics and bioacoustics. I have expertise in passive acoustic monitoring in terrestrial and aquatic ecosystems, acoustic signal processing and statistical analysis including generalized linear mixed models, structural equation models, machine learning methods and data mining.

I am mainly interested in understanding how the environment modulates sonic animal communities’ structure and dynamics to eventually help preserve the ecosystem integrity. Currently I’m working on a combination of simulation models and field-based surveys to assess variations in acoustic assemblages’ composition of marine mammals from the Southern Ocean. Together, with developing utilities to extract information from the acoustic environments including, sonic species identification, community indicators and habitat quality descriptors.
