A Costa Rican bacterial spiroplasma biodiversity survey in tabanid flies reveals new serogroups and extends United States ranges
Spiroplasmas are ubiquitous bacteria found in association with a wide range of plants and arthropods, where they can cause economically important diseases. To better understand Spiroplasma biodiversity and biogeography, a single host family (tabanid flies) was examined in detail. The current report describes spiroplasma carriage and biodiversity from tabanid flies captured at three sites in the Costa Rican...

Impact of interspecific competition by compatriot aquatic weeds on water hyacinth Eichhornia crassipes (Martius) Solms growth and development in the Kagera River
The phenotype of a plant is strongly influenced by the presence of neighbouring plants often resulting into change in growth and development. We have demonstrated to our knowledge for the first time, the influence of three aquatic weed species (Commelina sp., Justicia sp. and Vossia cupsidata) on growth and development of water hyacinth (Eichhornia crassipes). We found...

Diversity and distribution of amphibians in the Kakum National Park and its surroundings
This study investigated amphibian distribution and diversity in Kakum National Park and its surrounding communities. Sampling was carried out in lowland swampy areas and upland zones of both locations; thus totalling four main habitat types as areas of survey. A total of 1434 specimens belonging to four Families comprising 12 species of anurans were recorded. The 12 species were irregularly distributed in the four...

Correlation and path coefficient analysis of yield and its component in faba bean (Vicia faba L.) germplasm
Due to the lack of information on genetic diversity in Ethiopian faba bean (Vicia faba L.) germplasm and the need to study association among seed yield and related components, fifteen genotypes were grown at Sinana Agricultural Research Center and on two farmers’ field at Sinja and Adaba, south Eastern Ethiopia in 2007/08 cropping season. At Sinana, number of pods/plants, number of seeds/pod...

Flying with the enemy: An endoparasitic fly larva in Brazilian bumblebees
In the south of Brazil some species of bumblebees are disappearing, such as: Bombus bellicosus in Paraná State. Insecticides and other pesticides and global warming are possible candidates for such phenomena, but none of them has been deeply studied. In forest fragments at southeast of Brazil (Sorocaba City, São Paulo State) tachinid fly larvae were found inside the abdomen of foraging...

Proximate and mineral composition of four edible mushroom species from South India
Results of proximate analysis of four edible species of mushroom collected from different parts of IIT Chennai, Tamil Nadu, India., indicate that Auricularia polytricha was a very good source of crude protein (37%), crude fiber (21.97%), ash (6.87%), calcium (607 mg/g dry weight) and manganese (136 mg/kg dry weight (dw). Macrolepiota rhodocus was the richest in carbohydrate (48%) and magnesium (250...
