Toxicity bioassay and sub-lethal effects of diazinon on blood profile and histology of liver, gills and kidney of catfish, Clarias gariepinus

Abstract The catfish, Clarias gariepinus, was exposed to different acute concentrations (5-10 mg/l) of diazinon and the Lc50 value was Youth recorded as high as 7.3 mg/l for 96 hours.The fishes exposed to three sub-lethal levels of diazinon (0.73, 1.095 and 1.46 mg/l) for 30 days showed that the pesticide induces changes in different blood paramete

Identification of phlebotomine sand flies (Diptera: Psychodidae) by matrix-assisted laser desorption/ionization time of flight mass spectrometry

Abstract Background Phlebotomine sand flies are incriminated in the transmission of several human and veterinary pathogens.To elucidate their role as vectors, proper species identification is crucial.Since traditional morphological determination is based on minute and often dubious characteristics on their head and genitalia, which require certain

The marine leech Stibarobdella loricata (Harding, 1924) (Hirudinea, Piscicolidae), parasitic on the angel shark Squatina spp. and sandtiger shark Carcharias taurus Rafinesque, 1810 (Chondrichthyes: Squatinidae, Carchariidae) in Southern Brazilian waters

The presence of the marine leech, Stibarobdella Beach Texture Spray loricata (Harding, 1924) (Hirudinea, Piscicolidae), is reported on the southern coast of Brazil, based on seven lots with 47 specimens, between 71 and 182 mm in total length, collected on the dorsal region of angel sharks, Squatina argentina (Marini, 1930); S.guggenheim Marini, 193

Succession of ephemeral secondary forests and their limited role for the conservation of floristic diversity in a human-modified tropical landscape.

Both local- and landscape-scale processes ORG APPLE CIDER VINEGAR drive succession of secondary forests in human-modified tropical landscapes.Nonetheless, until recently successional changes in composition and diversity have been predominantly studied at the patch level.Here, we used a unique dataset with 45 randomly selected sites across a mixed-u
