Gryllus bimaculatus (Gb) was orally administered at doses of 0, 0.04, 0.2, 1 and 5 g/kg bw/day for 13 consecutive weeks. There were no observed clinical signs or deaths related to treatment in all the groups tested. Therefore, the approximate lethal oral dose of G. bimaculatus was considered to be higher than 5 g/kg in rats. Throughout the administration period, no significant changes in diet c...

In protein-coding genes, synonymous codon usage and amino acid composition correlate to expression in some eukaryotes, and may result from translational selection. Here, we studied large-scale RNA-seq data from three divergent arthropod models, including cricket (Gryllus bimaculatus), milkweed bug (Oncopeltus fasciatus), and the amphipod crustacean Parhyale hawaiensis, and tested for optimizati...

Three species of Synaphris occurring in the East Mediterranean - Synaphris orientalis Marusik & Lehtinen, 2003, Synaphris lehtineni Marusik, Gnelitsa & Kovblyuk, 2005 and Synaphris letourneuxi (Simon, 1884) - are surveyed; and a new species - Synaphris wunderlichisp. n. - is described from southern Israel on the basis of males. The new species differs from other East- Mediterranean congeners by...

•Lizards in Ihe Anolis bimaculatus group from the northern Lesser Antilles have played an important role in theoretical and empirical developments in ecology, behavior, and evolution over the last four decades. Despite intense interest, the lack of a formal phylogenetic analysis for the bimaculatus group has limited comparative and historical evolutionary analyses. Here we present a phylogeneti...

The Stenus flammeus group is proposed and twelve new species of the group are described: Stenus corniculus sp. n., Stenus daicongchaoi sp. n., Stenus jiajinshanus sp. n., Stenus jindingianus sp. n., Stenus paraflammeus sp. n., Stenus pengzhongi sp. n., Stenus pseudoflammeus sp. n., Stenus punctidorsus sp. n., Stenus tuyueyei sp. n., Stenus xilingmontis sp. n., and Stenus zhoudeyaoi sp. n. from ...

A variety of fishes consumed regularly are prone to pathogenic spoilage especially by different microbes. It is important find out microbiological quality fish that we consume protect the public health. Current research was conducted assess incidence Salmonella and Escherichia coli (E. coli) contamination in three selected catfish species namely, Ayer (Sperata seenghala), Pabda (Ompok pabda) Ma...

Spiders have become an important model to study the evolution of sociality, but a lack of their detailed natural history and taxonomy hinders broader comparative studies. Group-living crab spiders (Thomisidae) provide an excellent contrast to other social spiders since they lack a communal capture web, which was thought to be a critical factor in the evolution of sociality. Only three non-webbu...

O lambari, Astyanax bimaculatus, é uma das espécies nativas com potencial zootécnico para a aquicultura, e se destaca características desejáveis o cultivo, logo, estudos referentes à quantidade ideal de alimento são necessários melhorar desempenho da espécie. Sendo assim, objetivou-se avaliar descrever influência frequência alimentar sobre crescimento do A. bimaculatus. Matrizes A.bimaculatus f...
