Laura Cardador, Auteur ; José A. Díaz-Luque, Auteur ; Fernando Hiraldo, Auteur ; James D. Gilardi, Auteur ; José L. Tella, AuteurKnowledge of a species’ potential distribution and the suitability of available habitat are fundamental for effective conservation planning and management. However, the quality of information on the distribution of species and their required hab[...]
Article
Guillermo Blanco, Auteur ; Fernando Hiraldo, Auteur ; José L. Tella, AuteurParrots (Psittaciformes) have been viewed as efficient consumers of the reproductive structures of plants. Consequently, parrots have been excluded from studies focusing on plant–animal mutualistic relationships as they have been considered only[...]
Article
Francisco V. Dénes, Auteur ; José L. Tella, Auteur ; Steven R. Beissinger, AuteurEstimating abundance and population size is essential for many ecological and conservation studies of parrots. Achieving these goals requires methods that yield reliable estimates, but parrot traits can make them difficult to detect, count, and [...]
Article
Matthias Vögeli, Auteur ; David Serrano, Auteur ; María Méndez, Auteur ; José L. Tella, AuteurIntraspecific geographic variation in morphology is common in animals along geographic or climatic clines. Local ecological factors are likely to act simultaneously at smaller spatial scales, but have hardly been contrasted with wide-ranging pre[...]
Article
Luiza Figueira, Auteur ; José L. Tella, Auteur ; Ulisses M. Camargo, Auteur ; Goncalo Ferraz, AuteurForest regeneration may reduce the current loss of species due to tropical deforestation, but little is known about the extent and inter-specific variability of this effect. We compared the probability with which nine parrot species use old-grow[...]
Article
Erica C. Pacifico, Auteur ; Eduardo A. Barbosa, Auteur ; Thiago Filadelfo, Auteur ; Kleber G. Oliveira, Auteur ; Luís F. Silveira, Auteur ; José L. Tella, AuteurLear's Macaw Anodorhynchus leari is currently listed as Endangered by IUCN. Although it only breeds on cliffs at two protected sites in Bahia State, Brazil, there is no accurate information on population parameters such as the number of breeding[...]
Article
Martina Carrete, Auteur ; José L. Tella, Auteur ; Guillermo Blanco, Auteur ; Marcelo Bertellotti, AuteurPopulation growth and human development result in biodiversity loss and biological homogenization not only in developed countries, but increasingly in the less developed countries as well. In those countries, where urbanization and agricultural [...]

Vágási, Auteur ; Matthias Voegeli, Auteur ; Roger Jovani, AuteurFeather mites are arthropods that live on or in the feathers of birds, and are among the commonest avian ectosymbionts. However, the nature of the ecological interaction between feather mites and birds remains unclear, some studies reporting neg[...]

Martina Carrete, Auteur ; Juan M. Grande, Auteur ; José L. Tella, Auteur ; Jose A. Sanchez-Zapata, Auteur ; Jose A. Donazar, Auteur ; Ricardo Diaz-Delgadoa, Auteur ; Alfredo Romo, AuteurExtinctions are often the result of multiple factors that are difficult to disentangle and so methods for identifying simple and combined types of extinctions are valuable for both basic and applied ecology. We applied a modification of variance[...]

Abraham Rojas, Auteur ; Eleuterio Yucra, Auteur ; Ivan Vera, Auteur ; Andres Requejo, Auteur ; José L. Tella, AuteurThe Red-fronted Macaw Ara rubrogenys is endemic to Bolivia, where it is listed as "Critically Endangered" due to its reduced population size and persisting threats. This species is known to breed exclusively on steep cliffs in arid inter-Andean [...]
Article
Matthias Voegeli, Auteur ; David Serrano, Auteur ; Fernando Pacios, Auteur ; José L. Tella, AuteurMetapopulation theory is one of the most popular approaches to identify the factors affecting the spatial and temporal dynamics of populations in fragmented habitat networks. Habitat quality, patch area and isolation are mainly focused on when a[...]
Article
María Méndez, Auteur ; José L. Tella, Auteur ; Jose A. Godoy, AuteurIdentifying the genetic processes derived from habitat fragmentation is critical for the conservation of endangered species. We conducted an integrated analysis of genetic patterns in the endangered Dupont's lark (Chersophilus duponti), a circum[...]
Article
Miguel Alcaide, Auteur ; David Serrano, Auteur ; José L. Tella, Auteur ; Juan J. Negro, AuteurThe integration of capture-recapture and molecular approaches can improve our understanding of the consequences of habitat fragmentation on population connectivity. Here we employed microsatellites to test dispersal hypotheses derived from inten[...]
Article
Paola Laiolo, Auteur ; Matthias Voegeli, Auteur ; David Serrano, Auteur ; José L. Tella, AuteurIndividuals of some species differentiate each other on the basis of the acoustic features of their vocalizations, and this can be used in individual-based population monitoring studies. No research has tested for the effectiveness of individual[...]
