Two sibling bare-backed bat species (Pteronotus fulvus and P. gymnonotus) have been traditionally differentiated by their size. However, intermediate specimens between the two species have been found in sympatric populations along southern Mexico and it has been suggested that they may be the outcome of a hybridization process between the two speci...
Mating systems are studied due to their interest in ecology and evolution. In rodents, mating strategies have been inferred from the spatio-temporal arrangement of males and females, and breeding success has usually been estimated through the number of embryos counted by palpation of pregnant females. However, these might not be trustable proxies t...
Reliable estimates of nest‐switching are required to study avian mating systems and manage wild populations, yet different estimation methods have rarely been integrated or assessed. Through a literature review and case study, we reveal that three common methods for assessing nest‐switching blend different components, producing a wide range of esti...
El ADN ambiental (environmental DNA, eDNA) es una metodología para analizar el material genético liberado por individuos que han transitado o habitan en el medio muestreado con el objetivo de identificar las especies a las que pertenece dicho material. El tipo de muestreo es no invasivo y permite analizar varios taxones simultáneamente partiendo de...
Cryptic speciation and hybridization are two key processes that affect the origin and maintenance of biodiversity and our ability to understand and estimate it. To determine how these two processes interact, we studied allopatric and sympatric colonies of two cryptic bat species (Eptesicus serotinus and E. isabellinus) with parapatric distribution...
Paleontological, archaeological, and biogeographical evidences strongly suggest the common genet (Genetta genetta; Mammalia, Carnivora) was translocated by humans into Europe. A widespread hypothesis considers the Muslims, which conquered Iberia at the eighth century AD, as the putative agents of translocation. This hypothesis was reinforced becaus...
PCR is a universal tool for the multiplication of specific DNA sequences. For example, PCR-based sex determination is widely used, and a diversity of primer sets is available. However, this protocol requires thermal cycling and electrophoresis so results are typically obtained in laboratories and several days after sampling. Loop-mediated isotherma...
Understanding the ecological, behavioral and evolutionary response of organisms to changing environments is of primary importance in a human-altered world. It is crucial to elucidate how human activities alter gene flow and what are the consequences for the genetic structure of a species. We studied two lineages of the Egyptian fruit bat (Rousettus...
Tool use is widespread among animals and has been under intense study due to its prominence in human society and evolution. A lack of detailed genetic information for wild populations has perpetuated assumptions regarding associations between individual differences in tool use and cognition and learning processes. However, captive birds and mammals...
Roads are widely recognized to represent a barrier to individual movements and, conversely, verges can act as potential corridors for the dispersal of many small mammals. Both barrier and corridor effects should generate a clear spatial pattern in genetic structure. Nevertheless, the effect of roads on the genetic structure of small mammal populati...
Although many birds are socially monogamous, most (>75%) studied species are not strictly genetically monogamous, especially under high breeding density. We used molecular tools to reevaluate the reproductive strategy of the socially monogamous white stork (Ciconia ciconia) and examined local density effects. DNA samples of nestlings (Germany, Spai...
PCR-based methods are the most common technique for sex determination of birds. Although these methods are fast, easy and accurate, they still require special facilities that preclude their application outdoors. Consequently, there is a time lag between sampling and obtaining results that impedes researchers to take decisions in situ and in real ti...
The white stork, Ciconia ciconia, is a model species for studies of bird migration and behavior, but previously published genetic markers are not informative enough to perform individual-based genetic studies. Following discovery using next generation sequencing, 11 polymorphic markers were selected and tested in samples from two study sites. The n...
Anciently introduced species can be confounded with native species because introduction pre-dates the first species inventories or because of the loss of the collective memory of the introductions. The term 'cryptogenic species' denotes species of unknown or unclear status (native versus non-native) in a given territory, and disciplinary approaches...
The successful introduction of the common genet (Genetta genetta) into Europe has been traditionally associated to the Muslim invasion of Iberia, although diverse evidence suggested an earlier arrival. In this study, we assessed genetic variation at 11 microsatellite loci in 199 individuals from the Mediterranean Basin and used approximate Bayesian...
Animal movements exhibit an almost universal pattern of fat-tailed step-size distributions, mixing short and very long steps. The Lévy flight foraging hypothesis (LFFH) suggests a single optimal food search strategy to explain this pattern, yet mixed movement distributions are biologically more plausible and often convincingly fit movement data. To...
Habitat specialists inhabiting scarce and scattered habitat patches pose interesting questions related to dispersal such as how specialized terrestrial mammals do to colonize distant patches crossing hostile matrices. We assess dispersal patterns of the southern water vole (Arvicola sapidus), a habitat specialist whose habitat patches are distribut...
The southern water vole (Arvicola sapidus Miller, 1908) is an endangered rodent whose conservation guidelines should preserve the current genetic variability. We analyze the structure and organization of the mitochondrial control region (CR) in A. sapidus. The CR of this species is characterized by a low guanine-cytosine content, the absence of any...
Investigating the evolutionary history of the species is critical for understanding the evolution of biodiversity and for its conservation. Towards this goal, molecular approaches are becoming increasingly powerful with the incorporation of recent theoretical and analytical advances. Here, we apply an isolation-with-migration coalescent-based model...
The role of Southern European peninsulas as glacial refugia for temperate species has been widely established, but phylogeographic patterns within refugia are being only recently addressed. Here we describe the phylogeographic patterns for Southern water vole (Arvicola sapidus) in its whole distribution across Iberia and France. Control region and...
