Osmoregulatory findings on crabs from high Neotropical latitudes are entirely lacking. Seeking to identify consequences of evolution at low temperature, we examine hyper/hypo-osmotic and ionic regulation and gill ion transporter gene expression in two sub-Antarctic Eubrachyura from the Beagle Channel, Tierra del Fuego. Despite sharing the same osmo...

The trade of live crustacean species is a unique practice that attracts costumers by ensuring crab freshness. This seafood is consumed worldwide because of its nutritional value and positive impact on human health. However, few studies address the impact of the complex live-trade chain on the animal and meat quality parameters. We aimed to study th...

Temperature is an important abiotic factor that drives the evolution of ectotherms owing to its pervasive effects at all levels of organization. Although a species’ thermal tolerance is environmentally driven within a spatial cline, it may be constrained over time due to differential phylogenetic inheritance. At the limits of thermal tolerance, hem...
Article
Live transport of crustacean species is a relatively recent practice that increases the fisheries trade's chain of profits, without increasing the fishing effort. However, there are few biological and technological studies on developments to enhance animal welfare, reduce mortality rates and consequently avoid economic losses. We aimed to study dif...

Live transport to markets requires a baseline on the effects of temperature during air-exposure and the subsequent recovery in water. Our aim was to analyze the physiological effect of 24 h of air exposure in commercial male Lithodes santolla at different temperatures and subsequent re-immersion. Three groups of animals were air-exposed at three te...
Working Paper
Thermal tolerance underpins most biogeographical patterns in ectothermic animals. Macroevolutionary patterns of thermal limits have been historically evaluated, but a role for the phylogenetic component in physiological variation has been neglected. Three marine zoogeographical provinces are recognized throughout the Neotropical region based on mea...

Munida gregaria and M. subrugosa were originally described as two different species on the basis of several morphological characters, but recent studies evidenced that both former species constitute the same biological species, so hereafter they are referred to as two morphs of M. gregaria: 'gregaria' and 'subrugosa'. Notwithstanding their synonimi...
