Ecological invasions, where non-native species spread to new areas, grow to high densities and have large, negative impacts on ecological communities, are a major worldwide problem. Recent studies suggest that one of the key mechanisms influencing invasion dynamics is personality-dependent dispersal: the tendency for dispersers to have a different personality type than the average from a source...

Technological and analytical advances to study evolutionary biology, ecology, conservation of the Southern River Terrapin (Batagur affinis ssp.) are realised through molecular approaches, including DNA barcoding. We evaluated use COI barcodes in Malaysia’s population better understand species’ genetic divergence other characteristics. 26 sequences, four from field specimens Terrapins obtained B...

A critical review of the family Veliidae (Hemiptera: Heteroptera: Gerromorpha) in Romania is provided. In total, two genera and eight species (Microvelia Westwood, 1834-3 species, Velia Latreille, 1804-5 species) are known from the country. Microvelia buenoi Drake, 1920 and Velia serbica Tamanini, 1951 are recorded for the first time from Romania. The occurrence of V. affinis filippii Tamanini,...

The genus Cystacanthus was established by Anderson (1867: 457) and placed in tribe Ruellieae Dumortier (1829: 23) when published. In fact, it is closely related to Phlogacanthus Nees von Esenbeck (1832: 76, 99) and differs only in the corolla shape and indumentum. Thus, many authors merged Cystacanthus with Phlogacanthus (Benoist 1935, Imlay 1939, Brummit 1992, Mabberley 2008). But it was still...

Increasing bacterial resistance to commercial antibiotics has led to considering medicinal herb applications. This study aimed to identify chemical composition of essential oil of some native medical herbs and their antibacterial activity against Yersinia ruckeri compared with Enrofloxacin in in vitro experiments. The antibacterial activities of ethanolic extracts and essential oils of Eryngium...

Synopsis Here we review the literature of a male poecillid’s sexually dimorphic body plan, behavior, and nervous system, including work dating from the mid 1800s to the mid 1990s as well as work in press or in preparation for publication. Rosa-Molinar described the remodeling of the sexually dimorphic anal fin appendicular support, confirmed earlier claims about the development of the male and ...

The copepod Eurytemora affinis has an unusually broad salinity range, as some populations have recently invaded freshwater habitats independently from their ancestral saline habitats. Prior studies have shown evolutionary shifts in ion transporter activity during freshwater invasions and localization of ion transporters in newly discovered "Crusalis organs" in the swimming legs. The goals of th...

Objetctive: This experimental study aimed to assess the preference of Gambusia affinis mosquito larvae An.gambiae s.s., Cx. quinquefasciatus and Aedes aegypti. Method: Three were introduced in a glass container with dimension 45cm x 25cmx 25cm. densities used, 90 (30 per species), 120 (40 180 (60 species). Each density experiment was set triplicate monitored after 1, 2, 3, 24 hours. No fish foo...
