També comptarem amb unes breus intervencions de part de Hilmar Hinz i Julia Máñez Crespo. La idea és fer networking i poder xerrar més de tu a tu.  

Apuntau la data a l’agenda! Esperam que ens hi pogueu acompanyar! 

Salutacions 

Sandra, Raquel, Natalia.

Abstract

Join us for a captivating journey into the depths of oceanography as we share the highlights of an adventurous oceanographic cruise. From meticulous planning to unexpected events during the experiment, we'll unravel the excitement and challenges faced on the high seas. Our spotlight will be on the CALYPSO 2022 cruise, a thrilling exploration of the mesmerizing Balearic Sea.

Dive into the details as we explore the mission's primary goal: uncovering subduction regions that connect the sea surface with the depths below. The synergy of two ships and multiple observing platforms provided a comprehensive dataset on submesoscale motions.

Abstract

Understanding the extent of animal mortality, the where and when mortality occurs, is paramount to implement effective conservation actions and secure the persistence of animal populations. Unfortunately, so far our understanding of animal survival (which is the inverse of mortality) is very limited, even for well-studied species such as vultures. Project SURVIVALIST has the ambitious objective of filling this knowledge gap for three European vultures (Griffon, Cinereous and Bearded vulture). Based on a large collaborative network, SURVIVALIST collated a uniquely large dataset (including >1400 vulture individuals across the three species) of high-resolution vulture tracking data. These data are analysed using novel approaches to quantify survival in time across the species annual cycle (e.g. during the breeding and non-breeding season) and life-stages (juvenile, immature, adults; Objective 1). Survival variation for each species is then mapped across space by integrating survival modeling with space use from the tracking data, to identify hotspots of vulture mortality (Objective 2).

Abstract:

This thesis aims to comprehensively investigate the existence of chronotypes across different fish species and examines how environmental factors modulate them using cutting-edge fish tracking technologies. The thesis first investigates the presence of chronotypes in free-living fish species, clearly identifying these individual temporal patterns in several marine species. Fish behavior is known to be influenced by environmental factors. However, individuals within the same population can exhibit different responses to environmental gradients, referred to as behavioral reaction norms. Subsequently, the thesis describes a large-scale tracking experiment conducted to explore how those environmental gradients affect the expression of chronotypes in the pearly razorfish, Xyrichtys novacula. Behavioral traits typically covary, forming behavioral syndromes, yet few studies have explored chronotype-personality syndromes. This thesis proposes a novel methodological approach that combines laboratory and field experiments to quantitatively assess both classical and circadian-related behavioral traits in the pearly razorfish. Finally, it is well-established today that fishing exerts selective pressures on fish behavior. The final chapter of this thesis proposes a modeling approach to investigate whether exploitation by fishing may lead to directional selection on fish chronotypes. This PhD thesis introduces the field of marine eco-chronobiology, bridging gaps among three traditionally distinct disciplines: marine ecology, fisheries science, and chronobiology.

Abstract

In rainbow trout ( Oncorhynchus mykiss ) aquaculture a significant portion of the fish die (around 10%) or experience growth stunting (GS; around 10%), which represents an important profitability and welfare issue. In the presented study, we aimed at characterising the GS phenotype in seawater-transferred rainbow trout using untargeted and targeted molecular biology methods, discovering the implication of a variety of pathways. During this talk, each method used will be explained in detail, showcasing the capabilities of each one.

Seagrass meadows provide essential ecosystem functions and services. They serve as nursery habitats for fish, and the structural complexity is a key factor influencing this function. Despite their ecological importance, seagrasses are being degraded worldwide at an alarming rate, leading to a significant loss of habitat structure. In response to this trend, restoration projects have been developed in recent years, aiming to recover both habitat structure and associated functions We assessed the recovery of habitat structure and the associated nursery function within a restored Posidonia oceanica meadow. Additionally, we conducted habitat selection experiments with two species, Diplodus annularis and Symphodus tinca, to evaluate if they actively select seagrass habitats based on structural complexity. Our results revealed that, despite the presence of some fish species in the restored area, neither the structural complexity nor the nursery function had fully recovered. In the choice experiments, both species exhibited a clear affinity for seagrass habitats over unvegetated areas, demonstrating their ability to actively selected habitats based on visual cues. However, the response in occupancy patterns to increasing seagrass complexity was species-specific.Understanding how juvenile fish respond to changes in seagrass habitat features is crucial for quantifying the nursery service provision and for identifying effective measures to accelerate the restoration process.
