Research line: Ecology of populations and conservation of endangered Species
The “Ecology of Populations and Conservation of Endangered Species” research line at the Doñana Biological Station (EBD-CSIC) seeks to advance the mechanistic understanding of population dynamics while providing the scientific basis for the conservation and management of threatened species. Combining long-term ecological studies with approaches from movement ecology, functional ecology, ecophysiology, and conservation genomics, this research line has generated knowledge that supports evidence-based conservation and policy decisions. A strong commitment to applied research and knowledge transfer underpins all activities within this line.
Long-term studies at EBD-CSIC have been central to understanding how individual behaviour, environmental conditions, and demographic processes shape population dynamics. Studies of migratory birds have provided unique insights into the ecological and evolutionary mechanisms underlying migration, survival, and population persistence. An important component of this research has focused on insular and highly unpredictable systems.
This research line has also played a fundamental role in providing science-based support to regional, national, and international institutions in the management of endangered species such as the Iberian lynx, the Spanish imperial eagle, and the marbled teal. Research in conservation genomics has improved understanding of genetic erosion, inbreeding, demographic history, and adaptive potential in threatened populations, providing critical guidance for population management.
This research line has also addressed the conservation of species that perform key ecological functions. Long-standing work on scavenger ecology has advanced understanding of the role of vultures and facultative scavengers in ecosystem functioning while informing policy on issues such as carcass management, poisoning, veterinary pharmaceuticals, and human–wildlife interactions. Studies of large carnivore populations have made major contributions to understanding the covariates of human-wildlife conflicts and developing strategies to minimize them.
The conservation of aquatic species represents another major area of activity. Long-term studies on sea turtles combine research, monitoring, and citizen science to improve understanding of population connectivity, reproductive ecology, and emerging conservation challenges associated with changing environmental conditions. Additional research investigates the ecology of marine predators and the effects of fisheries on polar ecosystems. Historical ecology has also contributed to identifying factors associated with the decline of populations of critically endangered fish species.
By linking fundamental ecological processes with practical conservation solutions, this research line contributes to the recovery of endangered species, the maintenance of ecosystem functions, and the development of effective biodiversity conservation strategies in the face of global change.
