Population‐specific bycatch risks in two vulnerable anadromous clupeids: Insights from otolith microchemistryNARA Subscribed
Otolith microchemistry analysis revealed that bycatch of European shads, allis shad Alosa alosa and twaite shad Alosa fallax , in western Iberian commercial fisheries removes individuals from a wide array of natal origins, with the most abundant source rivers suffering the heaviest losses. Spatial variation in bycatch risk was evident: Specific marine areas exhibited high natal origin diversity, reflecting complex dispersal. A...
Actinobacillus seminis DnaK interacts with bovine transferrin, lactoferrin, and hemoglobin as a putative iron acquisition mechanismNARA Subscribed
Ovine epididymitis, caused by Actinobacilus seminis , is an infectious disease that produces atrophy of the testis, low fertility, and sterility in infected animals. Iron is a microelement necessary for different vital functions in all organisms and most microorganisms. A. seminis iron acquisition mechanisms are undiscovered. For this reason, this work aimed to know the mechanisms this bacterium possesses to respond when grown...
Molecular survey of herpesviruses in bats from Chile and Spain reveals potentially novel speciesNARA Subscribed
Bats (order Chiroptera) are known as important hosts and reservoirs for several zoonotic viruses. To this date, most virology studies in bats have focused on RNA viruses; consequently, information about DNA viruses is more limited. Herein we surveyed the presence of herpesviruses in blood or spleen samples of three bat species of Spain (n = 31) and five bat species of Chile (n = 50) by using a broad-spectrum nested PCR. Overal...
The influence of habitat heterogeneity on Nematoda communities in Posidonia oceanica meadowsNARA Subscribed
Nematodes typically comprise the most abundant phylum in meiofaunal communities. We aim to characterize the specific ecological conditions that influence Nematoda communities in Posidonia oceanica grasslands focusing on three habitats: leaves, matte, and unvegetated adjacent sediment. We hypothesized that the constant flux of nutrients under the canopy would result in a higher concentration of metazoans compared to the unveget...
Suboptimal growth among individuals of brown trout ( Salmo trutta ) in a temperate riverNARA Subscribed
This study assessed growth of individually tagged brown trout Salmo trutta in a temperate system of north‐west Spain (2010–2012). This study identified notable individual variation in fish growth with individuals growing sub‐optimally compared with laboratory‐based growth‐model predictions in most cases (85.5% of individuals). The present observations of suboptimal growth need to be considered in view of intraspecific competit...
Examining the link between dietary specialization and foraging modes of stream‐dwelling brown trout Salmo truttaNARA Subscribed
The aim of this study was to explore differences in dietary specialization across two foraging modes (benthic v . surface‐drift foraging) of stream‐dwelling brown trout Salmo trutta . The degree of inter‐individual niche variation within each foraging mode was high, but the dietary specialization was maintained between foraging modes. This study supports the view that if aquatic invertebrates are more abundant and accessible t...
