The present study estimated the human daily and weekly intake of inorganic elements due to consumption of fish in Rio de Janeiro state and the associated potential health risks posed by some toxic elements. All samples analyzed had values of Cd and Pb below the Maximum Tolerable Limits of 3.0 mg kg-1 for Pb and 1.0 mg kg-1 for Cd; only Mugil cephalus, Cynoscion leiarchus and Caranx crysos had A...

Background: Carangids, like any other fish, can become infected with a variety of external and internal parasites. Little information on parasite infestations in these fish species is known. This study aimed to provide light parasites that infect caragnids Saudi Arabia. Methods: A total 20 Carangoides caeruleopinnatus specimens were collected from the Red Sea (Saudi Arabia) then examined for pr...

From July 1979-December 1980, 48 springbok were culled for a parasite survey at Benfontein. Lice were the dominant parasites and reached a peak in September. Damalinia antidorcus, Linognathus antidorcitis, Linognathus armatus and Linognathus euchore were the most prevalent species, nymphs in most cases outnumbering adults. During the winter months, 2nd and 3rd instar Rhinoestrus antidorcitis an...

Species of Hypogastruridae and Onychiuridae described by D. L. Wray were reexamined and redescribed where necessary from type material and other specimens. Mitchellania hermosa is redescribed and transferred to Ceratophysella. Hypogastrura ireneae is redescribed and H. gravesi is validated with additional material. Hypogastrura gami is synonymized with H. humi and H. utahensis is synonymized wi...

Rock fragment fields are important habitat for biodiversity maintenance in coastal regions, particularly when located in protected areas dominated by soft sediments. Researches in this habitat have received surprisingly little attention on the Amazon Coast, despite rock fragments provide refuges, nursery grounds and food sources for a variety of benthic species. The present survey describes the...
