Extract from Gryllus bimaculatus crickets inhibits oxidation at the DNA level, with reduced production of 8-hydroxy-2'-deoxyguanosine (8-OHdG). Microarray analyses were performed with a rat 28K cDNA clone set array to identify the gene expression profiles of aged (10 months old) Wistar Kyoto rats treated for one month with 100 mg/kg G. bimaculatus ethanol extract to assess the effects. The extr...

Investigation on the hydrography and fish fauna were undertaken from a period of February to September, 2012 at selective locations in river Baitarini, Jajpur. Twenty eight species of fish belonging to six orders, eleven families and nineteen genera were collected. Order Cypriniformes was most dominant constituting 33.33% followed by Siluriformes (30.3%), Perciformes (12.12%) and others like Mu...

The objective of the present study was to evaluate the parasite fauna of four species of ornamental fish collected in the Chumucuí River, municipality of Bragança, Pará, Brazil. From June 2006 to December 2007. Fishes (n=307) belonging to four species were collected, including 23 specimens of Moenkhausia sanctaefilomenae (redeye tetra), 37 Carnegiella strigata (marbled hatchetfish), 7 Chilodus ...

Asprothrips bimaculatus sp. n. is described from Martinique. It is unique among the five species now recognised in this genus in having the body sharply bicoloured, with the head and thorax dark but the abdomen white.

The high mortalities registered in the larval stage during octopus culturing are mainly due to nutritional deficiencies of the food provided. To understand the cause of this problem, we studied the ontogenetic development of the digestive system of Octopus bimaculatus paralarvae. An egg batch was obtained from a gravid female collected in the Bay of Los Angeles, Baja California, Mexico, and it ...

Recently, fluctuating asymmetry (FA) of morphological traits has attracted great attention as a short-cut measure of individual quality. Whereas there is some evidence that FA of sexual ornaments is negatively associated with immune function, studies concerning FA and immune function in non-ornamental traits are absent. Here, we tested whether FA of three non-ornamental traits in hind limbs is ...

Length-weight relationship (LWR), condition factor (K) and stomach content of three cichlid fishes (Hemichromis bimaculatus, Sarotherodon melanotheron, and Chromidotilapia guentheri) were calculated at Eleiyele reservoir, Nigeria, Africa. The fish were collected monthly from fishermen during the dry season (January-March 2001) and the rainy season (April, May, June 2001). Gill nets of mesh size...

Five new species, Hylaeus (Hylaeus) wuae sp. nov., H. (Hylaeus) napacus sp. nov., H. (Hylaeus) neatifrons sp. nov., H. (Hylaeus) bimaculatus sp. nov. and Hylaeus (Prosopis) ikudomei sp. nov. are described and illustrated from Yunnan, China. The diagnosis of each species is provided. In addition, Hylaeus cardioscapus Cockerell, 1924 is recorded from China for the first time.

In Astyanax (Poecilurichthys), we recognize six species-groups defined by the distribution of melanophores on body: 1. bimaculatus; 2. rupununi; 3. abramis: 4. orthodus; 5. asuncionensis; and 6. anterior, which are named for a representative species. brevoortii1 is redescribed using specimens from Trinidad (including types). This species, as member bimaculatus species-group, distinguished lacki...

We observed expression patterns of hedgehog (hh), wingless (wg), and decapentaplegic (dpp) during gut development of Gryllus bimaculatus (the cricket), a typical hemimetabolous insect, and compared with those observed in Drosophila, a typical holometabolous insect. Gryllus hh(Gbhh) and Gbwg are expressed in both foregut and hindgut, while Gbdpp is expressed only in the hindgut: at the boundarie...
