The Datong and Xiaotong rivers are karst tributaries in the upper Yangtze River drainage represent considerable habitat diversity that contributes to high fish rich fishery resources two rivers. During few decades, have abruptly declined due overfishing, water pollution degradation. In order further strengthen conservation restoration of provide scientific support for management these rivers, t...

The evolution of alarm signals has puzzled evolutionary ecologists for decades. This is particularly true for alarm cues (‘Schreckstoff’) which are present in many fishes. They are passively released through injuries and signal the presence of a predator. Although the benefits for conspecific receivers are obvious (they can adjust their behavior to avoid predation), those for the senders are no...

Scolytinae, a large group of Coleoptera, are vital community that causes forest damage. Species such as Pityokteines curvidens (Germar), Orthotomicus erosus (Wollaston), Tomicus destruens minor (Hartig) and Ips sexdentatus (Boerner) particularly prevalent in the region. In recent years, prevalence bark beetle species causing tree damage Bursa province has increased. The purpose this study was t...

We investigated the taxonomic status of recently described kukri snake Oligodon arenarius Vassilieva, 2015 and morphologically similar macrurus (Angel, 1927), two species endemic to southern coast Vietnam. Based on phylogenetic analyses using three mitochondrial genes (12S–16S rRNA, cytochrome b ), we recovered O. in a clade within cyclurus-taeniatus group, agreeing with previous intrageneric c...

OBJECTIVE To compare the efficacy and safety of three polyspecific antivenoms for bites by pit vipers. DESIGN Randomised double blind comparative trial of three antivenoms. SETTING Shell, Pastaza, southeastern Ecuador. PARTICIPANTS 210 patients with incoagulable blood were recruited from 221 consecutive patients admitted with snake bite between January 1997 and December 2001. INTERVENTI...

The megadiversity of the neotropical ichthyofauna has been associated to recent diversification processes, reflecting in subtle or lacking morphological differentiation between species, challenging the classical taxonomic identification. Leporinus friderici occurs in several river basins of South America, and its nominal taxonomic validity has been questioned. Its wide distribution within the B...

A longitudinal study design was employed to collect Stomoxys flies between January, 2010 and December, 2011 from three different agro ecological settings, Sebeta, Debre Zeit and Fentale Districts, Ethiopia using vavoua traps. The study on the trapped Stomoxys flies was carried out with the aims of identification of Stomoxys species and comparison of the distribution, seasonality and relative ab...

The study of ichthyoplankton composition, abundance and distribution is paramount to understand the reproductive dynamics local fish assemblages. analysis these parameters allows identification spawning sites, nursery areas migration routes. However, due lack characters in early life stages, morphological often impractical many studies identify only larvae. Additionally, its accuracy shows grea...

Ofall amphibians living in arid habitats, reed frogs (belonging to the super species Hyperolius viridiflavus) are the most peculiar. Froglets are able to tolerate dry periods of up to 35 days or longer immediately after metamorphosis, in climatically exposed positions. They face similar problems to estivating juveniles, i.e. enduranee of long periods of high temperature and low RH with rather l...
