Antarctic krill ( Euphausia superba ) is a key species of the Southern Ocean, impacted by climate change and human exploitation. Understanding how these changes affect distribution abundance crucial for generating projections Ocean ecosystems. Krill growth an important indicator habitat suitability series models have been developed used to examine potential at different spatial temporal scales. The available using range empirical mechanistic approaches, providing alternative perspectives...
Understanding the vertical migration behaviour of Antarctic krill is important for understanding spatial distribution, ecophysiology, trophic interactions and carbon fluxes this Southern Ocean key species. In study, we analysed an eight-month continuous dataset recorded with ES80 echosounder on board a commercial fishing vessel in southwest Atlantic sector Ocean. Our analysis supports existing hypothesis that swarms migrate into deeper waters during winter but also reveals high degree...
Antarctic krill is a species with fundamental importance for the Southern Ocean ecosystem. Their large biomass and synchronized movements, like diel vertical migration (DVM), significantly impact ecosystem structure biological carbon pump. Despite decades of research, mechanistic basis DVM remains unclear. Circadian clocks help organisms anticipate daily environmental changes, optimizing adaptation. In this study, we used recently developed activity monitor to record swimming individual,...

Abstract Antarctic krill (Euphausia superba) are integral to Southern Ocean pelagic ecosystems. Winters with extensive sea ice have been linked high post-larval recruitment the following spring, suggesting that plays a critical role in larval overwinter survival. As ocean warms and declines under climate change, understanding mechanisms linking is increasingly urgent. To address this, we developed qualitative network model (QNM) integrates evidence-based hypothesized interactions explore...
Understanding the relationship between biodiversity and both functioning stability of ecosystems has been a central focus ecologists for decades. A step-change in our understanding biodiversity-ecosystem was enabled by explicit measurement additional provided through comparing expected observed yields multi-species communities. However, we lack an equivalent measure stability. Here, quantify net effect on using model simulations microcosm experiment that exposed different phytoplankton...

Abstract Antarctic krill ( Euphausia superba , hereafter krill) is a pelagic living crustacean and key species in the Southern Ocean ecosystem. Krill builds up huge biomass its synchronized behavioral patterns, such as diel vertical migration (DVM), substantially impact ecosystem structure carbon sequestration. However, mechanistic basis of DVM unknown previous studies behavior laboratory were challenged by complex large variability. Using new experimental set-up, we recorded swimming...
Abstract Ecosystems worldwide are experiencing a range of natural and anthropogenic disturbances, many which intensifying as global change accelerates. Ecological responses to those disturbances determined by both the vulnerabilities species their interspecific interactions. Understanding how individual contribute (in‐)stability an aggregated community property, or function, is fundamental ecological management conservation. Here, we present framework identify contributions stability based...
Abstract Background Krill ( Euphausia superba ) and salps Salpa thompsoni are key macrozooplankton grazers in the Southern Ocean ecosystem. However, due to differing habitat requirements, both species previously exhibited little spatial overlap. With ongoing climate change-induced seawater temperature increase regional sea ice loss, can now extend their distribution into historically krill-dominated areas rapidly asexual reproduction when environmental conditions favorable. Understanding...

Multifrequency echosounders are versatile devices commonly used in commercial fisheries, fisheries science and biological oceanography for the detection, quantification even identification of organisms suspended underlying water column. They produce data that is rich information, but can be tedious to process, often relying on expensive software. The aim our overarching research project was analyze vertical distribution Antarctic krill swarms ( Euphausia superba ) different seasons regions...
