The Iberian lynx (Lynx pardinus) has a highly restricted geographic distribution, limited even within the Iberian Peninsula. The last national survey reported less than 200 remaining individuals, distributed in two isolated areasAndújar-Cardeña and Doñana-and in consequence, the Iberian lynx was listed by the International Union for Conservation of Nature as "Critically Endangered". In this study, we estimate the Iberian lynx population size in the Doñana area using capture-recapture analysis of cameratrapping data. A model with different capture probability for each individual (M h ) yielded an estimate of 26 Iberian lynxes (SE=5.26) more than 1 year old. It is considered that a small slant in the estimation of the number of individuals could exist due to the presence of dispersers inside the study area that were not detected. Our study shows: (1) a reduction in number since the 1980s (45 individuals), and falling below the theoretical threshold of genetic viability, (2) changes in the species' spatial distribution in this area, and (3) as for other carnivore species, photographic capture-recapture methods are applicable for estimating the size of Iberian lynx populations
The Rüppell's Vulture (Gyps rueppelli) is listed as ‘Critically Endangered’ at the global and regional levels in the IUCN Red List of Threatened Species. A multi-institutional collaboration to fit 13 vultures with GPS transmitters in northern Morocco was launched to get information on their movements and threats along the flyway, both to the north and the south of the Sahara. Preliminary results from individuals released in November 2021 indicate a low survival rate during the wintering period in Morocco and on the return journey to the Sahel, which is usually attempted by Rüppell's Vultures with large groups of migratory birds, especially Griffon Vultures (Gyps fulvus). Of the group of tagged individuals, only four birds travelled definitely in a southwards direction, apparently migrating. Two of those have died, with one presumed to have starved in the Algerian desert, and another one presumed to have been killed by human persecution in The Gambia. A third individual was captured by local people in Mauritania and it is unknown what happened thereafter. One bird remains alive in Senegal at the time of writing. For the birds that did not disperse far after being fitted with transmitters, a relatively high number of fatalities seems to confirm that threats to the species are prevalent in Morocco: one bird died after being struck by a wind turbine; one was electrocuted by a power line; and two suffered from starvation and weakness. Birds remaining close to the release area fed mainly at a vulture feeding station or at rubbish dumps, which may indicate that there is a lack of food available in the wider surroundings. Five vultures originally fitted with transmitters are still alive in North Africa at the time of writing.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
