In this work we studied the acoustic variability in the induced release call on wild populations of the European common frog Rana temporaria. We used a computational model to analyze the induced release calls in both sexes. Our analysis detected three different acoustic phenotypes: (a) Non-canonical males comprised a large part of the population an...

The aim of this study was to develop a computational model to perform a bioacoustic characterization of the release call of a high-mountain population of Rana temporaria. We also wanted to determine the way in which variation in specific anatomical structures, such as the nostrils and mouth cavities, affected call structure. For this purpose, we re...

The introduction of non-native species is one of the factors driving the global decline of amphibians. We examined the effect of fish stocking in naturally fishless mountain lakes and ponds on the local populations of the European common frog (Rana temporaria). We surveyed 215 mountain lakes and ponds and noted the presence or absence of frogs and...

Anatomic indexes have proven to be an essential tool in the study of anatomicdifferences between and within species (Simoenset al.1994a, Gapert and Last 2004,Muthukumaret al.2005, Chr ́oszczet al.2006). They are often used in descriptivestudies; however, these indexes are only accurate within very narrow parameters, andthus are only useful for very...

An ecosystem is generally sustained by a set of integrated physical elements forming a functional landscape unit—ecotope, which supplies nutrients, microclimate, and exchanges matter and energy with the wider environment. To better predict environmental change effects on ecosystems, particularly in critically sensitive regions such as high altitude...

In low nutrient alpine lakes, the littoral zone is the most productive part of the ecosystem, and it is a biodiversity hotspot. It is not entirely clear how the scale and physical heterogeneity of surrounding catchment, its ecological composition, and larger landscape gradients work together to sustain littoral communities. A total of 114 alpine la...

A lo largo de la historia se ha debatido sobre la importancia de los factores internos de los organismos y externos a ellos como claves de la evolución (Gould, 2002). En los últimos años este debate se ha centrado en si la selección natural es la que dirige la evolución operando a través de la optimización adaptativa de los caracteres, o si, por el...

The occipital bone is an area of great adaptive value for Cetaceans in general and Odontoceti specifically due to it containing critical systems for the animal, such as the blood supply system for the brain and the hindbrain, a neural system that in Odontoceti it is thought to play an important role in echolocation and navigation. The aim of this s...

The great sensitivity of amphibians to land disturbance is one of the main causes that contributed to their worldwide decline. One fundamental approach in assessing amphibian ability to reflect habitat degradation is to measure their phenotypic changes in contrasting environments. We examined the extent to which several morphological traits of the...

Consumption of raw fish or improperly cooked fish can cause large and serious diseases in humans as an intermediate accidental host. Since 1960 when was described Anisakiasis in humans, the number of Anisakiasis cases has been increased worldwide reaching over 34,000, almost half of them recorded in Japan. Anisakis spp. is a very common parasite am...

Predatory aquatic beetles are common colonizers of natural and managed aquatic environments. While as important components of the aquatic food webs they are prone to accumulate trace elements, they have been largely neglected from metal uptake studies. We aim to test the suitability of three dytiscid species, i.e.Hydroglyphus pusillus, Laccophilus...
