The impact of invasive alien species on native communities can act at different levels both by affecting the ecosystem’s structure (i.e., mainly in case vegetation) and through direct interactions competition for food or space). Behavioral studies under controlled conditions provide relevant information potential invaders local species. In laboratory, resources between oriental shrimp Palaemon ...

HIGHLIGHTS Fluoxetine increases the metabolic rate and excretion of ammonia in both species. O:N ratio fish showed higher values highest concentrations fluoxetine. The LC50 - 96 hour Palaemon pandaliformis represented greater toxicity. Both species are a good biological model for fluoxetine exposure studies.

The development of type II clustered regularly interspaced short palindromic repeats (CRISPR) system has resulted in the revolution of genetic engineering and this technology has been applied in genome editing of various species. However, there is no report about the target-specific genome editing in shrimp. In this research, we developed the microinjection method for the ridgetail white prawn ...

The osmoregulatory ability and salinity tolerance of four species of decapod crustaceans (Decapoda: Natantia) were evaluated to test the degree of physiological adaptation to variations in salinity (2 d exposure to 10, 20, 25 and 32. The ecophysiological salinity tolerance of two penaeids (Metapenaeus joyneri and Penaeus semisulcatus) and two palaemonid species (Palaemon pacificus and Exopalaem...

We compare the genetic structuring and demographic history of two sympatric caridean shrimp species with distinct life history traits, one amphidromous species Palaemon capensis and one marine/estuarine species Palaemon peringueyi, in the historical biogeographical context of South Africa. A total of 103 specimens of P. capensis collected from 12 localities and 217 specimens of P. peringueyi co...

Mitochondria from the embryos of brine shrimp (Artemia franciscana) do not undergo Ca(2+)-induced permeability transition in the presence of a profound Ca(2+) uptake capacity. Furthermore, this crustacean is the only organism known to exhibit bongkrekate-insensitive mitochondrial adenine nucleotide exchange, prompting the conjecture that refractoriness to bongkrekate and absence of Ca(2+)-induc...
