Effect of exogenous foods used in Oreochromisniloticus (Linné, 1758) feed on the diversity and structure of phytoplankton in Blondey fishponds (Ivory Coast; West Africa)

Fish farmers generally use exogenous foods to increase fish production. However, these external inputs of food are most often at the base of the increased fertilization of the fishponds. This could unbalance the native flora and fauna in these artificial hydro systems. The aim of this study is to evaluate the effect of three exogenous […]

Diversity and structure of ant communities associated with Toxoptera aurantii (Boyer, 1941) (Hemiptera, Aphididae) in cocoa farms in the Centre Region of Cameroon: Role of anthropogenic activities

Ant species encountered with hemipterans are or not associated with them. In such associations, ants disseminate hemipterans on the host plants, protect them from their enemies or from climate constraints. The study of diversity and variation of ant species compositions associated with Toxoptera auranntii was conducted from March 2020 to February 2021 on cocoa trees […]

Family diversity of benthic macroinvertebrates and water quality of the Tendo lagoon (Southeast Côte d’Ivoire)

This study was conducted to assess the biological health of Tendo lagoon, which is the natural receptor of coastal streams and the Tanoe River by determining the Hilsenhof index. Macroinvertebrates samples were collected each month from February 2017 to March 2018 at 4 stations using a Van Veen grab. Abiotic variables (transparency, temperature, pH, dissolved […]

The influence of Formica exsecta ants on the abundance and diversity of other invertebrates in a private fragment of Tanzanias coastal forests

This study was conducted in the fragment of Tanzania’s Coastal Forests (TCFs), which is one of the world’s ecoregions with varied endemic flora and fauna located on the coast of Indian Ocean. Its focus was on privately-owned TCFs, specifically a research and conservation centre of the late Prof. R.B.M Senzota since 1988. This fragment faces […]

Study on Fish biodiversity of some landing sites and markets of Barpeta District, Assam, India

In a study conducted in the Barpeta district of Assam, India, 60 species of fishes belonging to 9 orders and 23 families were identified. Data collection was done by survey of landing sites and markets and information collected from fishermen. Order wise abundance of fish species are Osteoglossiformes 02; Clupeiformes 01; Cypriniformes 22; Characiformes 01; […]

Fish Biodiversity of Kapotakshma River Upstream, Jashore, Bangladesh

Analyzing fisheries resources and fish biodiversity in rivers is essential, and riverine fisheries play a crucial role in Bangladesh. The Kapotakshma River system is one of the significant river systems in the southwestern region of Bangladesh. This investigation was conducted to evaluate the fish diversity, seasonal distribution, and abundance of this river’s headwaters. The sampling […]

Diversity index of species in sandbar present in estuarine ecosystem of Agusan River, Philippines: Its threat, management and conservation

Estuary is a unique ecosystem due to the gradients of ecological conditions from riverine to marine. In some cases, there is sandbar in an estuary which rarely gets attention in scientific activities and conservation management. At the mouth of the Agusan River, the Philippines, where freshwater from the Agusan River and saltwater from Butuan Bay […]

Ethnobotanical exploration and biodiversity conservation of Mt. Nacolod, Southern Leyte, Philippines

This study was conducted in Mt. Nacolod, Southern Leyte, Philippines, to document traditional healing potential and practices of medicinal plants. The knowledge of traditional healing practices in Southern Leyte is at risk of being lost due to lack of knowledge transfer and an aging population of traditional healers. Focus group discussions were used to document […]

The diversity of aquatic insects in Assam, North-East India: A Review

India is one of the world’s mega-biodiversity hotspot nations. A class of arthropods known as aquatic insects can be found on or on the surface of lacustrine or riverine ecosystems where they complete their life cycle in water bodies. Eight main insect orders live their whole lives in the freshwater habitat. The functioning of aquatic […]

Bioclimatic and habitat variability shape the diversity and distribution of aquatic and invasive macrophytes in the floodplains of Indo-Burma biodiversity hotspot

Climate plays a major role in determining plant species richness and distribution patterns at a continental scale. However, a detailed investigation is necessary to understand the effect of climatic variations on species richness and distribution patterns at a regional scale, as other factors such as habitat types and associated environmental conditions exert significant influence at […]
