Gymnophthalmids are a highly diverse group of Neotropical lizards and its species richness is still in process discovery. The incorporation molecular evidence noticeable increase taxon geographic sampling systematic studies has led to the description numerous new genera gymnophthalmids (particularly Cercosaurinae) recent years. Herein we describe genus cercosaurine lizard with crocodile-like mo...

Genetic diversity as an important marker of the ecological status of aquatic ecosystems is considered a unique and powerful tool to evaluate biological communities. In order to evaluate the genetic diversity among golden mullet species (Liza aurata) in the southeast and southwest coasts of the Caspian Sea by D-Loop gene sequencing, a total of 23 fin specimens of golden mullet were collected fro...

The grey mullet fingerling were imported to Iran in 1997 from Hong Kong and in coastal fish pond of north part of Iran were successfully cultured in order to obtain broodstocks and induce artificial reproduction. Seasonal changes in serum concentrations of Testosterone, 17-β Estradiole (E2), 17-α Hydroxy Progesterone and also the level of calcium, Triglyceride and cholesterol in femal...

We revise the species of anoles occurring along the Pacific versant of Mexico west of the Isthmus de Tehuantepec in the states of Oaxaca, Guerrero, and Puebla. Based on our analyses of morphological and molecular genetic data, we recognize 21 species, six of which we describe as new (i.e., Anolis carlliebi sp. nov., A. immaculogularis sp. nov., A. nietoi sp. nov., A. sacamecatensis sp. nov., A....

In this study, the level of polycyclic aromatic hydrocarbons and heavy metals (Pb, Cr, Zn, Cd, Cu, Fe Mn) contamination were determined in Nile tilapia, Mullet fish Crab collected from crude oil polluted rivers (Abuloma Woji Jetty). Average individual PAHs concentration ranged 0.0001mgkg-1 to 11.22±0.02mgkg-1 13.43±0.17mgkg-1 mullet 12.23±0.06mgkg-1 crab. Benzo[a]pyrene (a carcinogenic PAH) con...
