Aedes ( Ochlerotatus ) lepidus (Cerqueira & Paraense, 1945) is reported from a cave in Templo dos Pilares Municipal Park, Mato Grosso do Sul state, Brazil. A single exploratory collection of culicids was carried out using CDC light traps on 16 November 2015. Four larvae and 11 adults (1♂, 10♀) were collected. The foundin water-filled hole stone. This the first record...

Two species of cerambycid beetles that attack eucalypts, Phoracantha semipunctata (Fabricius) and P. recurva Newman, have been accidentally introduced from Australia into most regions of the world in which their hosts have been planted. The beetles cause extensive mortality in plantations and landscape plantings of the trees. Management programmes have focused on integration of silvicultural pr...

The chub is an opportunistic, rheophilic cyprinid species and popular gamefish distributed throughout almost all of Europe, South Caucasus and part of Anatolia. It is most abundant in small rivers and large streams. The process of anatomical and cytological differentiation was analyzed in chub gonads. Material used in the study was derived from artificial spawning of adult individuals caught in...

The population genetic structure and historical demography of the flathead mullet Mugil cephalus were investigated using the mtDNA control region (CR) sequences (909-1015 bp) of 126 individuals collected from seven locations in the north-west Pacific between 2005 and 2007. Haplotype diversity (h = 0.9333-1.000) and nucleotide diversity (pi = 0.0046-0.1467) varied greatly among the sampling loca...

Total length, body mass and gut content mass of young-of-the-year (YOY) perch Perca fluviatilis, dace Leuciscus leuciscus and bleak Alburnus alburnus were recorded over the summer of 2006 at three littoral sites at Upper Lake Constance. In P. fluviatilis and L. leuciscus, gut content mass correlated positively with wave-induced energy flux (E(F)) of the respective site and sampling day, while n...

the aim of this study was to determine and compare the concentration of copper (cu) in liver and muscle of two fish species squalius cephalus and capoeta capoeta gracilis. the fish were caught in four sampling sites along tajan river, mazandaran province, northern iran. the concentration of cu was determined using flame atomic absorption spectrometry. there were significant differences (p

Some myotoxic or neurotoxic PLA2s (phospholipases A2) from pit viper venoms contain characteristic N6 substitutions. Our survey of the venoms of more than ten pit viper genera revealed that N6-PLA2s exist only in limited Asian pit vipers of two genera, Protobothrops and Gloydius, and exist as either monomers or the basic subunits of heterodimers in some New World pit vipers. For the newly ident...

RÉSUMÉ. Révision phylogénétique du genre Squalius (Actinopterygii, Cyprinidae) en péninsule Ibérique, avec description de deux nouvelles espèces. L’utilisation de caractères morphologiques et moléculaires a permis de réévaluer la diversité réelle du genre S q u a l i u s en péninsule Ibérique. Une analyse phylogénétique fondée sur l’étude de séquences complètes du gène mitochondrial cytochrome ...

Fatty acid composition of fish is one of the key factors for the evaluation of fish nutritional value and it could be different based on fish species, habitat, nutrition and etc. The aim of the present study was to evaluate the fatty acid composition of five commercially important freshwater fish from the fish market. Studied fish were as follows: Barbell, Luciobarbus pectoralis (Heckel, 1843),...
