The effects of land use and land cover change on freshwater snail distribution in Katana region, Democratic Republic of Congo
Land use and land cover change is a factor that significantly affects the loss of biodiversity and distribution of species. Remote sensing through satellite imagery and land use and land cover classifications systems can identify certain locations where freshwater snails have colonized in ecosystems that have changed over time. The objective of this study is […]
Microbial examination of drinking water supply systems of Elobeid city, Sudan
The present investigation was carried out to evaluate the microbial parameters of Elobeid drinking water supply systems, which comprise of Bara underground water system and the surface rainwater harvesting (RWH) system, during the period from July 2010–June 2011. Four samples from Bara and nine from RWH were collected. The microbial parameters were determined using different […]

Diversity of hairy ark cocklealong northern coast of Java, Indonesia and their variation in phenotypical traits
Hairy ark cockleis one of the bivalves of family Arcidae. High similarity on morphology among species of hairy ark cockles leads to difficulty in identification. Hence they are categorized as cryptic species. Due to variability of habitat, hairy ark cockles may develop variation in morphology as a result of adaptation. This study was aimed at […]
