Bigaan river is around 19 kilometers (km) from Gango, Libona, Bukidnon down to Cagayan de Oro City (Philippines) and ends up in the Macajalar Bay. This study investigated species composition and abundance of gastropods along the river’s stretch during wet and dry seasons. Sampling areas differ in elevation. Three species were found to be relatively […]

Lichens biodiversity in Uttarakhand and significance of precise species identification for promoting lichen conservation and trade

Uttarakhand is considered a reservoir of lichen-diversity. Besides their economic importance, lichens are valuable biomonitors of air pollution. At present, approximately 747 species of lichens are reported from the state of Uttarakhand. This study aims at studying the lichen biodiversity of the Kumaun and Garhwal region of Uttarakhand using secondary data, from published literature. In […]

Phenotypic identification of Candida species from various clinical samples in a resource limited setting

Candidiasis is worldwide in distribution, and is one of the common fungal diseases isolated in man, which affects the skin, mucosa and various internal organs. It is caused by various species of Candida, which is a yeast-like fungi that produce pseudohyphae. Speciation helps to understand the epidemiology of Candida species particularly, the source and mode […]

Ecological impacts of fragmentation on the diversity and distributions of indigenous tree species in tropical rainforest of Nigeria

This study investigated the ecological impacts of fragmentation on diversity and distributions of indigenous tree species in Nigerian rainforest, with the aim to ascertain how fragmentation impacted on the species of Ceiba pentandra, Irvingia gaboneensis, Piptadeniastrum africanum, Milicia excelsa, Musanga cecropioides, and Pentaklepta macrophylla. The study was carried out in 42 randomly selected matured rainforest […]

Fitness of Plankton Species on the Physico-Chemical Conditions of Umalag River, Tablon, Cagayan de Oro City, Philippines: A Species Distribution Modeling Approach

Plankton species are found in different environmental conditions due to various requirements for their survival and reproduction.  These species have adapted to the rapid changes in their environment that resulted from natural selection.  Anthropogenic activities have driven and defined the distribution of species and their interaction with the environment. To understand the species diversity and […]

Effects of siltation on water quality, community structure and diversity of mangrove species of a mining operation in Hinatuan Island, Taganaan, Surigao del Norte, Philippines

Mangroves are important ecosystems that provide protection of the coastal areas by trapping sediments from inland activities, particularly mining. However, they are facing various challenges from anthropogenic activities resulting in sedimentation and siltation. This study aimed to demonstrate the extent of siltation through visual satellite imageries, compare the water physico-chemical characteristics, and diversity of two […]

Speciation of heavy metals in fish species in the wetlands of oil-bearing communities of the Niger Delta

This study investigated the heavy metals concentration in 3 fish species: Tilapia zilli, Clarias spp, and Chana obscura in the wetlands of oil-producing states of the Niger Delta. In carrying out this study, 5 oil-bearing communities were randomly selected from 5 randomly selected Niger Delta states and fish samples were randomly collected from the wetlands […]

Woody Species Diversity and Traditional Management Practices in Parkland Agroforestry in Gombora District, Hadiya Zone, Southern Ethiopia

This study was carried out in the southern Ethiopia to identify traditional management practices and woody species diversity in parkland Agroforestry. Reconnaissance and diagnostic surveys were conducted in the two agro-ecological zones. Then, 85 sample households were randomly selected from each wealth category based on the proportions. Systematic sampling method was used to collect woody […]

Seaweeds species in Tres Marias, Palompon, Leyte, Philippines

Seaweeds are important marine life. It has several uses people can avail of. The taxonomy of seaweeds plays an important component in the successful bid for its proper management, conservation, and preservation. The study was on seaweeds species found in the three islets of Palompon, Leyte. The investigation was on chlorophytes (green seaweeds), phaeophytes (brown […]

Bioaccumulation of heavy metals in some pelagic and benthic fish species in selected wetlands in oil-bearing communities of the Niger Delta

This study focused on the determination of heavy metals content of three fish species: Clarias spp, Chana obscura and Tilapia zilli, in the wetlands of 5 Niger Delta oil-producing communities. The samplings which were carried out with the assistance of artisanal fishermen lasted for 6 months from March to September 2021. The samples collected were […]
