Melatonin has been identified in a variety of crustacean species, but its function is not as well understood as in vertebrates. The present study investigates whether melatonin has an effect on crustacean hyperglycemic hormone (CHH) gene expression, oxygen consumption (VO2) and circulating glucose and lactate levels, in response to different dissolved-oxygen concentrations, in the crab Neohelic...

White spot syndrome virus (WSSV) continues to be the most severe viral pathogen shrimp industry worldwide. Pacific white Litopenaeus vannamei is particularly affected by WSSV, and this has been detected in a wide range of wild crustaceans, including penaeid non-penaeid crayfish, as well crabs. Crabs have considered dangerous threat farms because they are generally believed highly tolerant WSSV ...

We report a rich faunal assemblage from the Tyrrhenian (Late Pleistocene) of Trumbacà, located in the southern area of Reggio Calabria (Calabria, southern Italy). The only brachyuran reported to date from this locality is Ranilia constricta (A. Milne Edwards, 1880) by Vazzana (2008). The studied specimens have been assigned, as follows: ?Corallianassa sp., Dardanus arrosor (Herbst, 1796), Darda...

Abstract With its large size and range of habitats, Texas has one the most diverse insect faunas United States with many endemic species. Despite more than a century active study, knowledge diversity in remains incomplete. Here, we report 19 species subspecies records Mantodea, Orthoptera, Phasmatodea for first time (USA) based on museum specimens. These include several significant geographic e...

1. According to meta-population models, a superior competitor and a superior disperser can coexist in a patchy environment. The two anemonefishes, a large aggressive Amphiprion clarkii Bennett and a small less-aggressive A. perideraion Bleeker, use the same host anemone Heteractis crispa Ehrenberg on a coral reef, Okinawa, Japan, where most of the hosts disappeared after the coral bleaching in ...
