River networks are among Earth’s most threatened hot-spots of biodiversity and provide key ecosystem services (e.g., supply drinking water and food, climate regulation) essential to sustaining human well-being. Climate change and increased human water use are causing more rivers and streams to dry, with devastating impacts on biodiversity and ecosy...

Ammonia is a pollutant frequently found in aquatic ecosystems. In fish, ammonia can cause physical damage, alter its behaviour, and even cause death. Exposure to ammonia also increases fish physiological stress, which can be measured through biomarkers. In this study, we analysed the effect of sublethal ammonia concentrations on the behaviour and t...
Article
The European Water Framework Directive (WFD) mandates to incorporate the participation of stakeholders and the general public in the development and updating of the river basin management plans. So far, the WFD implementation has been mainly focused on perennial rivers without considering temporary rivers properly, neither in biomonitoring programs...
Article
Wetlands such as rice paddies are important ecosystems that provide habitat for a numerous range of species but are considered as a major source of mercury in the most toxic form of methylmercury. An in situ mesocosm experiment was conducted during the rice cultivation season of 2018 in rice paddies from the Ebro Delta (NE, Spain) to investigate th...

Temporary rivers are characterized by shifting habitats between flowing, isolated pools, and dry phases. Despite the fact that temporary rivers are currently receiving increasing attention by researchers and managers, the isolated pools phase has been largely disregarded. However, isolated pools in temporary rivers are transitional habitats of majo...
Article
There is a tendency for the wolves of a pack to stay together assuming that there is a social bond between the pack members. A rough estimate of the strength of this bond can be obtained by measuring the distances between pack members. The aim of this study was to determine the inter-individual distance by calculating the Euclidian distance to dete...
Article
How the morphology of captive-reared fish is affected by structural enrichment in their rearing tanks is not well understood. Some studies have suggested that deficiencies in rearing environments could produce inappropriate body shape in salmonids (Vehanen and Huusko 2011). Garduño-Paz et al. (2010) have found significant differences in body and he...

Mediterranean rivers are severely affected by pollutants from industry, agriculture and urban activities. In this study, we examined how industrial pollutants, many of them known to act as endocrine disruptors (EDCs), could disturb the reproduction of the Catalan chub (Squalius laietanus). The survey was conducted throughout the reproductive period...

We studied the behavioral responses of three brown bears (Ursus arctos) to different types of enrichment devices to assess the predominant pattern of animal–enrichment interaction (PAI) to each type of enrichment. We assessed the bears' responses to feeding, sensory, and occupational enrichments over nine sessions. Using Pearson's correlation (r) a...
Article
A significant body of literature suggests that aquatic pollutants can interfere with the physiological function of the fish hypothalamic-pituitary-interrenal (HPI) axis, and eventually impair the ability to cope with subsequent stressors. For this reason, development of accurate techniques to assess fish stress responses have become of growing inte...

Sexual selection is considered the major cause of sexual dimorphism, but recent observations suggest that natural selection may play a more important role in the evolution of sex differentiation than previously recognized. Therefore, studying the trade-offs between natural selection and sexual selection is crucial to a better understanding of the e...
Article
In fish the response to stress is usually assessed by quantification of short-term changes in blood cortisol levels (Baker, Gobush, & Vyne, 2013), the main glucocorticoid (GC) in most teleosts (Mommsen, Vijayan, & Moon, 1999). Blood provides only a snapshot of the hormonal profile at one point in time. An alternative source for cortisol measurement...
Poster
In Europe, the implementation of the Water Framework Directive has been unable to provide a solution to determine the ecological status of Intermittent Rivers and Ephemeral Streams (IRES). A lack of adequate methods (developed exclusively for perennial streams), hydrological data, and limited recognition in environmental policies have posed a major...

The density of brown trout (Salmo trutta) in some mesohabitat and sites of Flamisell river (Catalan Pyrenees) was studied through electrofishing. The trout population of this river is predominantly composed by fry and juvenile fishes, while the adult population is relatively lower. This lower density indicates that adult trout prefer pools, while n...

One of the unresolved problems of male sexual aggregations is that a small number of males monopolize most matings. The Common Quail (Coturnix coturnix (L., 1758)), is a bird species that has a short life span and a reproductive strategy that involves male aggregations, which females visit for the purpose of mating. Once a mate has been chosen, bir...
