The hepatopancreas of the mangrove crab Neosarmatium africanum: a possible key to understanding the effects of wastewater exposure (Mayotte Island, Indian Ocean).
Mangrove crabs are ecosystem engineers through their bioturbation activity. On Mayotte Island, the abundance of Neosarmatium africanum decreased in wastewater-impacted areas. Previous analyses showed that global crab metabolism is impacted by wastewater, with a burst in O2consumption that may be caused by osmo-respiratory trade-offs since gill functioning was impacted.
Is digestive cathepsin D the rule in decapod crustaceans? Comparative Biochemistry and Physiology B-Biochemistry & Molecular Biology.
Cathepsin D is an aspartic endopetidase with typical characteristics of lysosomal enzymes. Cathepsin D activity has been reported in the gastric fluid of clawed lobsters where it acts as an extracellular digestive enzyme. Here we investigate whether cathepsin D is unique in clawed lobsters or, instead, common in decapod crustaceans.
Proteinases during early development of the Pacific Whiteleg Shrimp Penaeus vannamei.
During shrimp larval development, changes occur in molecular components. Enzyme activity and mRNA expression of proteinases were assayed in Penaeus vannamei during larval development, which consists of 5 nauplius stages, 3 protozoeal stages, 3 mysis stages, and 12 postlarval stages. Trypsin activity reached a maximum at the beginning of postlarval stages 1 and 2, and significantly decreased in subsequent postlarval stages.
Molecular aspects of lipid metabolism in the midgut gland of the brown shrimp Crangon crangon
The brown shrimp,Crangon crangon, is well adapted to the variable environmental conditions in the southernNorth Sea. It is very abundant, has high reproduction rates, and holds a key position in coastal ecosystems.
Seasonal lipid dynamics of the shrimps Crangon crangon and Pandalus montagui in the German Bight (North Sea).
Environmental fluctuations can impose energetic constraints on organisms in terms of food shortage or compensation for metabolic stress.
Transcriptome analysis of the midgut gland of the brown shrimp Crangon crangon indicates high polymorphism of digestive enzymes.
Tolerance of organisms towards heterogeneous and variable environments is highly related to physiological flexibility.
Interactive responses to temperature and salinity in larvae of the Asian brush-clawed crab Hemigrapsus takanoi: relevance for range expansion into the Baltic Sea, in the context of climate change
We studied the potential of a recently introduced species, the Asian brush-clawed crab (Hemigrapsus takanoi), to expand its distribution range further into the Baltic Sea. H. takanoi has been documented in the southwestern Baltic Sea since 2014.
Race to the poles: the thermal response of the transcriptome of two range-expanding pelagic amphipod species
Climate change, proceeding at an unprecedented pace, is currently redistributing life on Earth (Pecl et al., 2017). Its impacts are strongest in polar regions and both the Arctic and Southern Oceans are experiencing rapid environmental changes.
