--This study examined habituation of the predator inspection behavior in the guppy (Poecilia reticulata) and its relationship with boldness (open field locomotion). Two different strategies were discovered: (1) initial inspection of a predatorlike fish, correlated with boldness; (2) subsequent surveillance, governed by a random underlying process and unrelated with boldness. The surveillance in...

freshwater fish biodiversity is a precious natural asset in terms of economic, cultural and scientific interest. and yet, the inland freshwater ecosystem in malaysia is declining at a far greater rate than terrestrial ecosystems in the tropics. what happened, and what is being done to address the crisis? this paper extracts findings from the latest literature and explores overarching issues per...

Millions of scientific specimens are housed in museum collections, a large part which fluid preserved. The use formaldehyde as fixative and subsequent storage ethanol is especially common ichthyology herpetology. This type preservation damages DNA reduces the chance successful retrieval genetic data. We applied ancient extraction single stranded library construction protocols to variety vertebr...

The SI is composed 22 publications, being two review 20 original articles. A total 107 researchers contributed to these papers, involving 44 institutions based Brazil six...

In order to monitor the developmental features of embryos, larvae, and juveniles of Oryzias latipes (Temminck and Schlegel), Oryzias latipes was caught in river of Shinduck-dong, Yeosu-si, Jeollanam-do, on May 2011, and experiments were carried out in Ichthyology laboratory at Chonnam National University.
