Understanding the decline of the Cantabrian Capercaille (Tetrao urogallus cantabricus)
Adan is PhD Student of Moncho Obeso at the Ecology Unit at the University of Oviedo, Spain. He stayed several times in Leipzig to develop a spatially-explicit and individual-based population model for the Cantabrian Capercaille.
Adáns project includes models for habitat selection, based on data from periodic fieldwork, as well as predictive statistical models for construction of maps of habitat quality maps for the entire metapopulation. Finally, the habitat maps will be the input for a spatially-explicit and individual-based dispersal model and a population model. The results of Adáns project will improve the understanding of the capercaillie population responses to changes in landscape structure and other aspects of their conservation biology. Further, the project will also enable us to develop objective methods for choosing between management options for capercaillie conservation.
Project in Leipzig
The objective in Leipzig is the development of a spatially explicit and
individual-based simulation model for capercaillie. The model is arranged around
the vital cycle processes from an individual perspective. The model takes into
account both environmental and demographic stochasticity, as they usually play a
main role in the decline and extinction of small and isolated populations. To
determine factors and processes in which management actions must focus, Adán
investigates the influence of the different demographic parameters on the
extinction probability. In addition, he will analyze the viability under
different scenarios of management derived from plausible improvements in habitat
quality and in the demographic parameters.
