Alejandro Ordonez Gloria

I am global change ecologist, whose research centers on gaining insights into how past and present global environmental changes shape diversity patterns and ecosystem process, and the implication of these changes for conservation. Currently, I am a postdoctoral researcher at Aarhus University, where I am part of the ERC-project “Macroecological studies of long-term historical constraints on functional diversity and ecosystem functioning across continents - HISTFUNC”.

The aim of my work is answering the question “how to conservation ecology should respond to the challenges imposed by global changes?”. I have approached this question using a broad geographical and temporal perspective centered on extensive comparative studies. For this, I have combined large-scale and deep-time ecological databases, with recent conceptual and methodological advances in biogeography, macroecology, paleoecology, spatial ecology, ecophysiology, community ecology and phylogenetics. My current research focuses on three areas. First, creating metrics to measure the exposure to past and present environmental changes, and assess to what extent these changes would result in novel ecosystems. Second, evaluating to what extent shallow and deep time historical environmental changes define present species and functional diversity, and possibly ecosystem functioning. Third, establish how human activities act as drivers of ecosystem change, and the implication of this for nature management and conservation efforts. Through this research, I hope to understand, predict, and advise on future ecosystem behavior in the face of earth’s changing ecological, biogeochemical, climatic and disturbance gradients.
