Ecological applications : a publication of the…
2006

The main objective of many conservation programs is to increase population size by improving a species' survival and reproduction. However, density dependence of demographic parameters may confound… (More)

Testing the Goodness of Supplementary Feeding to Enhance Population Viability in an Endangered Vulture

Daniel Oro, Antoni Margalida, Martina Carrete, Rafael Melgarejo Heredia, José Antonio Donázar
PloS one
2008

BACKGROUND Human-predator conflicts are directly or indirectly threatening many species with extinction. Thus, biologists are urged to find simple solutions to complex situations while avoiding… (More)

Diet and food preferences of the endangered Bearded Vulture Gypaetus barbatus : a basis for their conservation

The Bearded Vulture Gypaetus barbatus population in the Pyrenees is managed using feeding stations to increase breeding success and reduce mortality in the pre-adult population. Nevertheless, very… (More)

Sanitary versus environmental policies : fitting together two pieces of the puzzle of European vulture conservation

Antoni Margalida*, José A. Donázar, Martina Carrete and José A. Sánchez-Zapata Bearded Vulture Study and Protection Group, Apdo. 43, El Pont de Suert, E25520 Lleida, Spain; Department of Conservation… (More)

Sources of variation in mortality of the Bearded Vulture Gypaetus barbatus in Europe

We analyse the causes of mortality for the Bearded Vulture in Europe. Shooting (31%), intentional poisoning (26%), collision (18%) and unintentional poisoning (12%) were the most important causes of… (More)

2011

Toxoplasma gondii is a zoonotic intracellular protozoan parasite of worldwide distribution that infects many species of warm-blooded animals, including birds. To date, there is scant information… (More)

A computational modeling for real ecosystems based on P systems

Mónica Cardona, M. Angels Colomer, +4 authors Delfí Sanuy
Natural Computing
2010

In this paper, a P systems based general framework for modeling ecosystems dynamics is presented. Particularly, ecosystems are specified by means of multienvironment P systems composed of a finite… (More)

Modeling Ecosystems Using P Systems: The Bearded Vulture, a Case Study

Mónica Cardona, M. Angels Colomer, Mario J. Pérez-Jiménez, Delfí Sanuy, Antoni Margalida
Workshop on Membrane Computing
2008

The Bearded Vulture (Gypaetus barbatus) is an endangered species in Europe that feeds almost exclusively on bone remains of wild and domestic ungulates. In this paper, we present a model of an… (More)

Assessing the risk of lead exposure for the conservation of the endangered Pyrenean bearded vulture (Gypaetus barbatus) population.

Mauro Hernández, Antoni Margalida
Environmental research
2009

Acute and chronic lead (Pb) poisoning have been recognized as some of the most important causes of mortality for raptors worldwide. We simultaneously examined the recent, medium-term and long-term… (More)

Too sanitary for vultures.

José Antonio Donázar, Antoni Margalida, Martina Carrete, José Antonio Sánchez-Zapata
Science
2009

Mouse embryos survived freezing to -196°C. Survival required slow cooling (0.30 to 2°C per minute) and slow warming (40 to 250C per minute). Depending on the specific rates used, 50 to 70 percent of… (More)
