Carbon sequestration potential of selected tree species in Bolila Malita, Davao Occidental Philippines

This study determined the carbon sequestration potential of selected tree species in Bolila, Malita Davao Occidenta, Philippinesl. Twenty-seven (27) individuals trees were selected, measured, and calculated namely, Gmelina (Gmelina arborea), Mahogany (Swietenia mahagoni), Ipil-Ipil (Leucaena leucocephala), and Molave (Vitex parviflora) using line transect and non-destructive methods. Based on this results, Gmelina (G. arborea) has the […]

Species diversity, forest structure and composition of the Mangrove forest in the Sangalang locality, Biliran Island, Philippines

Mangrove forests contribute to the diversity, richness and productivity of coastal ecosystems. Unfortunately, these forest types are vulnerable to both human-caused and natural disturbances. In order to learn more about their diversity, structure and composition, and disturbance impact, nine permanent plots were established across three transect lines in Sangalang mangrove forest. The results showed a […]

Avian species in selected mangrove areas in Siocon, Zamboanga del Norte, Mindanao, Philippines

With the rampant habitat destruction of wildlife in the Philippines, the avifauna is the most affected as endemism in the archipelago is so high. Siocon, Zamboanga del Norte potentially harbors several Mindanao threatened endemic species in its Siocon Resource Reserve, a patch of secondary mature lowland forest as well as in mangrove areas. Opportunistic sampling […]

Feeding preference of drywood termite Cryptotermes cynocephalus Light (Kalotermitidae) against common furniture wood species in the Philippines

Drywood termites are known as household pests attacking furniture and other wood products. A free-choice and no-choice feeding test were conducted to determine the feeding preference of Cryptotermes cynocephalus Light to common furniture wood species in the Philippines, viz., Gmelina arborea Roxb, Swietenia macrophylla King and Acacia mangium Willd. The analysis of mass loss, wood […]

Diversity, distribution and conservation status of mangrove species in the Municipality of Biliran, Biliran Island, Philippines

We determined the diversity of mangrove species and their conservation status in the municipality of Biliran to serve as baseline for conservation and protection of mangal ecosystems in the island. Thirty-two quadrats with a size of 10×10 m were established and each mangrove tree inside the plots was identified. The numbers of individuals per species […]

A critical study on wild species of Solanum distributed in Dibrugarh District of Assam

The genus Solanum L. is the largest genus in Solanaceae family, with around 1250 species worldwide. The present study aims to characterize the morphological and anatomical account of six wild species of Solanum namely, S. nigrum L., S. americanum Mill., S. viarum Dunal, S. torvum Sw., S. indicum L., and S. aethiopicum L. collected from […]

Species composition, diversity and community structure of mangroves in Barangay Fabio, Tagana-an, Surigao Del Norte, Philippines

Mangrove ecosystems serve a crucial environmental role in protecting coastlines from storms, floods, and erosion, and they aid as a breeding ground for many marine life. Mangrove forests are declining due to relentless anthropogenic activities. Thus, the assessment of mangrove species plays a crucial part in the upkeep and protection of the forest. This study […]

Bioaccumulation of Lead (Pb) content in three species bivalves in Jakarta Bay, Indonesia

Environmental pollution by heavy metals has become a serious problem in Jakarta Bay. Mobilization of heavy metals as a result of anthropogenic activities has caused the release of heavy metals into the environment, one of which is Pb. Several methods already used to clean up the environment from these kinds of contaminants, but most of […]
