First record of the bushy-tailed opossum, Glironia venusta, Thomas, 1912, (Dide...
Calzada, Javier; Delibes, Miguel; Keller, Claudia; Palomares, Francisco; Magnusson, William ErnestUm indivíduo de Glironia venusta (Didelphimorphia), foi observado na Reserva Florestal Adolpho Ducke, Manaus, Amazonas, Brasil. Existem apenas 17 outros registros publicados desta espécie de marsupial, a maioria da década de 80. No Brasil, G. venusta havia sido registrada em três outras localidades, no Pará, Amazonas e Rondônia. Com este registro em uma das áreas mais intensivamente estudadas na Amazônia, ganha...
Spatiotemporal Dynamics of Genetic Variation in the Iberian Lynx along Its Path...
Casas-Marce, Mireia; Marmesat, Elena; Soriano, Laura; Martínez-Cruz, Begoña; Lucena-Perez, Maria; Nocete, Francisco; Rodríguez-Hidalgo, AntonioThere is the tendency to assume that endangered species have been both genetically and demographically healthier in the past, so that any genetic erosion observed today was caused by their recent decline. The Iberian lynx (Lynx pardinus) suffered a dramatic and continuous decline during the 20th century, and now shows extremely low genome- and species-wide genetic diversity among other signs of genomic erosion....
Fecal nitrogen concentration as a nutritional quality indicator for european ra...
Gil-Jiménez, Esperanza; Villamuelas, Miriam; Serrano, Emmanuel; Delibes, Miguel; Fernández, NéstorMeasuring the quality of the nutritional resources available to wild herbivores is critical to understanding trophic regulation processes. However, the direct assessment of dietary nutritional characteristics is usually difficult, which hampers monitoring nutritional constraints in natural populations. The feeding ecology of ruminant herbivores has been often assessed by analyzing fecal nitrogen (FN) concentrat...
Fish invading deserts: non-native species in arid Moroccan rivers
Clavero, Miguel; Esquivias, Javier; Qninba, Abdeljebbar; Riesco, María; Calzada, Javier; Ribeiro, Filipe; Fernández, Néstor; Delibes, Miguel1. Desert rivers are highly dynamic systems in which dry periods, frequently involving the cessation of superficial flow, alternate with violent flash floods. In spite of their territorial importance and high functional and biological diversity, desert rivers have received little attention in the scientific literature, especially in Northern Africa. 2. This study investigated the distribution of non‐native fish...
Conservation biogeography of ecologically interacting species: the case of the ...
Real, Raimundo; Barbosa, A. Márcia; Rodríguez, Alejandro; García, Francisco J.; Vargas, J. Mario; Palomo, L. Javier; Delibes, MiguelAim: To assess overlooked conservation problems of the Iberian lynx by exploring biogeographic relationships with its staple prey, the European rabbit. Location: The Iberian Peninsula. Methods: We modeled environmental favorability for the lynx based on its distribution before 1989, and for the rabbit using distribution data collected primarily after its population crash of 1989. We used the latter as a current...
