“…October to February, high season), whereas for the rest of the year, its abundance remains lower (i.e. March to September, low season) [ 40 , 55 ]. To corroborate this, we calculated the monthly distribution of the average proportion of tagged sharks present per day and receiver.…”

Essential habitats support specific functions for species, such as reproduction, feeding or refuge. For highly mobile aquatic species, identifying essential habitats within the wider distribution range is central to understanding species ecology, and underpinning effective management plans. This study examined the movement and space use patterns of sevengill sharks ( Notorynchus cepedianus ) in Caleta Valdés (CV), a unique coastal habitat in northern Patagonia, Argentina. Seasonal residency patterns of sharks were evident, with higher detectability in late spring and early summer and lower during autumn and winter. The overlap between the residency patterns of sharks and their prey, elephant seals, suggests that CV functions as a seasonal feeding aggregation site for N. cepedianus . The study also found sexual differences in movement behaviour, with males performing abrupt departures from CV and showing increased roaming with the presence of more sharks, and maximum detection probability at high tide. These movements could be related to different feeding strategies between sexes or mate-searching behaviour, suggesting that CV may also be essential for reproduction. Overall, this study highlights the importance of coastal sites as essential habitats for N. cepedianus and deepens our understanding of the ecological role of this apex predator in marine ecosystems.

“…Durante octubre de 2019 se realizó un muestreo piloto a fin de evaluar técnicas no destructivas para estimar la abundancia relativa de peces medianos y grandes. Se realizaron muestreos con estaciones de video fijas con cebo (BRUVS, por sus siglas en inglés Baited Remote Underwater Video Stations) (Trobbiani et al 2021), sesiones de pesca con mosca y censos visuales de peces mediante buceo libre (Irigoyen et al 2013). En una primera etapa, se definieron a los pozones del río como unidades de muestreo.…”

Ante la crisis global de pérdida de biodiversidad y deterioro de los ecosistemas, las áreas naturales protegidas tienen un rol preponderante como herramienta de manejo. Sin embargo, la mayoría se basa sobre criterios terrestres, mientras que los organismos de agua dulce son los más amenazados en cuanto a su conservación. En este trabajo se analiza el efecto de protección del Parque Nacional El Rey y de una crecida estival del río Popayán, de la cuenca del río Bermejito, sobre las poblaciones de peces de interés pesquero (el dorado [Salminus brasiliensis], el sábalo [Prochilodus lineatus] y la boga [Megaleporinus spp.]). Se realizaron estimaciones de abundancia y de talla mediante censos visuales antes y después al evento de crecida, y también dentro y en los límites del área protegida, en un contexto de presión de pesca por parte de pescadores furtivos. No se registró un efecto significativo de la crecida sobre las especies en estudio, pero sí del efecto del área protegida: en su interior se registró que las tres especies eran muy abundantes y que el dorado poseía tallas mucho mayores. Los resultados muestran que el área protegida cumple un rol esencial como sostén de las especies en estudio, sobre todo en el caso del dorado.

“…Arthropods constitute an important component of animal biodiversity on Earth and form part of many trophic levels, which makes them highly relevant for ecological studies (Minelli et al, 2013). The Trichoptera have been studied worldwide and until now the main method used was extractive; however, for the purposes of ecological management, conservation, and research, extractive sampling techniques are unethical or counterproductive (Trobbiani et al, 2021). For this reason, this work aims to provide an effective tool, once individuals have been identified, for monitoring populations of this order without requiring the extraction of individuals even during rainy days.…”

The aim of this study was to evaluate the performance of Underwater Video Stations (UVS) to detect caddisfly larvae (Trichoptera), estimate density in a lake, as well as to evaluate its effectiveness in tracking larvae. For this, were deployed UVS. Recording a total of 3120 minutes of video were analysed, of which 968 min were used for abundance analysis. Finally, caddisfly larvae were tracked using the Tracker software, which recorded the velocity of everyone in mm/s. This work successfully put into practice a novel sampling methodology for this insect group. The technique was implemented quickly, easily, and inexpensively and is highly scalable for the monitoring of aquatic invertebrates. Remote video stations are a potential tool for use in the field of population monitoring and studies of personality and behaviour in the natural habitat.
