The RNA sequencing data sets available for different fish species show a potentially high variety of forms enzymes just in teleosts. This is primarily considered an effect the first round whole-genome duplication with mutations duplicated genes (isozymes) and alternative splicing mRNA (isoforms). However, abundance transcript variants not necessarily reflected active proteins. We have investiga...

The Cikaniki resort is one of the most accessible research stations located in Gunung Halimun Salak National Park (GHSNP). It adjacent with Citalahab village. Research Center for Biology, Indonesian Institute Sciences and other institutions have conducted intensive on fauna diversity GHSNP from this station. Here we formulate a checklist surrounding Station Citalahab, GHNSP various sources, i.e...

The order Odonata (Insecta) is composed of aquatic insects popularly known as dragonflies and damselflies. Members this are closely linked to the conservation status their habitats; however, Wallacean shortfall in some regions still remains high. Volta Grande do Xingu region have high endemism groups, such Actinopterygii (fish), which can be applied other groups that not yet fauna at site, Odon...

Resistin (encoded by Retn) was previously identified in rodents as a hormone associated with diabetes; however human resistin is instead linked to inflammation. Resistin is a member of a small gene family that includes the resistin-like peptides (encoded by Retnl genes) in mammals. Genomic searches of available genome sequences of diverse vertebrates and phylogenetic analyses were conducted to ...

Soon after its discovery in 1938, the coelacanth Latimeria was rega...

The white sturgeon, Acipenser transmontanus, is a primitive bony fish that is recognized as an important emerging species for aquaculture. However, many aspects of its stress and reproductive physiology remain unclear. These processes are controlled by various steroid hormones. In order to investigate the regulation of steroidogenesis associated with acute stress in sturgeon, a cDNA-encoding st...

Using comparative phylogenetic analysis, we analyzed the evolution of male alternative reproductive tactics (MARTs) in ray-finned fishes (Actinopterygii). Numerous independent origins for each type of MART (involving sneaker males, female mimics, pirates, and satellite males) indicate that these behaviors have been highly labile across actinopterygiian evolution, consistent with a previous noti...

Six reproductive classes of male Oligosarcus hepsetus (Cuvier, 1829), a medium-sized carnivorous Characiform species, are described based on macroscopic and histological techniques. A total of 175 individuals were caught monthly between April 2001 and June 2002 in the Lajes Reservoir, Brazil, one of the largest impoundment areas in the state of Rio de Janeiro. The reproductive classes were base...
