Research topics

Large-scale Conservation

The exploration and analysis of animal and plant traits, distributions and needs across the globe with their particular threats, conservation needs, and applied conservation interventions. We use advanced modelling techniques to elucidate different patterns and set conservation targets for example in modelling conservation status and threat per species. We also explore the spatial effects of altered/protected landscapes, their utility and the formal algorithmic prioritization of conservation effort and designation of regions for conservation.

Conservation Culturomics and iEcology

Culturomics is a form of computational lexicology that studies human behavior and cultural trends through the quantitative analysis of digitized texts. Conservation culturomics is a new field that aims to look at human-nature interactions as these are manifested in the, ever expanding, digital realm. These interactions can prove extremely insightful in both understanding the patterns behind human interest, value, and knowledge towards nature and conservation. Such insights could prove to be key in both allocating funds for conservation projects, increasing their visibility and success, and ultimately incorporating social aspects of conservation on a broad scale in a quantitative fashion. iEcology is a linked field which is defined as the study of ecological patterns and processes using data generated for other purposes and stored digitally. While using similar sources as conservation culturomics, iEcology focuses on basic ecological and evolutionary patterns that can be arise from them.

Spatial Ecology and Conservation

We are also very interested in various patterns of interactions between organisms and their environment at local to landscape scales. Humans are constantly converting more natural habitats to human-dominated ones. This has great ramifications on most organisms. The application of both remotely sensed data, available spatial datasets and new data acquired through observation and tracking of wild animals and plants in the field is invaluable for our ability to understand spatial dynamics of organisms and our capacity to identify species-specific conservation needs and interventions.

The National Conservation Index

In the era of the Sixth Mass Extinction, habitat loss, pollution, invasive species, and hunting are all contributing to biodiversity loss – wildlife and plant populations are diminishing at an unprecedented pace.
We have been part of the team that has been developing the Nature Conservation Index (NCI) as a valuable tool to assess the effectiveness of countries’ conservation efforts.
The NCI uses 25 key indicators to provide an unadjusted, straightforward look at biodiversity and conservation across 180 countries. It examines various factors like protected area coverage, species at risk, conservation laws, and future trends. This detailed view helps us spot problems, track progress, and make better decisions about protecting our planet and promoting sustainable development, to ultimately support a more effective global approach to biodiversity protection and sustainable development.
