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...

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...

During routine inspection of a colony of albino western mosquitofish Gambusia affinis, approximately 10 females were discovered to have distended abdominal cavities. Cause for the distention was investigated by examination of tissue sections from four sacrificed individuals, all of which suffered severe ascites. Hermaphroditic gonads were seen in two of the fish.

Ceylon Medical Journal The wasp (Vespa affinis) is common and widely distributed in Sri Lanka. Wasp venom is known to contain factors that release histamine, enzymes, haemolysins, neurotoxins and vasodilators [1]. Case reports with severe multi-organ dysfunction after wasp stings are few in literature. We report two patients who developed severe multi-organ dysfunction following multiple wasp b...

We isolated nine microsatellite loci from the Neotropical understorey tree Miconia affinis (Melastomataceae) and optimized them for research on gene flow and genetic structure. Loci screened in 43 individuals from a 2.26-km(2) region were shown to be unlinked and polymorphic, with 5 to 14 alleles per locus and observed heterozygosity ranging from 0.394 to 0.810.

The main focus of this research is to ascertain the X-ray diffraction (XRD) pattern, Fourier transform infrared (FTIR) spectroscopic and surface morphology a hornet (Vespa affinis) nest. optical microscopic (OM) analysis demonstrated that nest presented an irregular formation partition materials. This was confirmed via scanning electron microscopy (SEM), which revealed presence unique form with...
