The study deals with the phytosociological analysis and regeneration status of tree species in the forests of Barella Range and Sohagpur Range in Madhya Pradesh, India. The tree density varied between 1095/ha to 1050/ha. The value of Shannon-Weaver index (H′) varied between 2.26 and 2.71, which...

Rare tree species make a significant contribution to the species richness in natural tropical forests but often they are endangered. Integrating them into plantation schemes is an important option for biodiversity conservation. In the Visayas, Philippines, we surveyed tree nurseries with a focus on ...

In the present study, acetylcholinesterase (AChE), butyrylcholinesterase (BChE), and tyrosinase inhibitory and antioxidant activities of the fruit and leaf extracts of Melia azedarach L. (Meliaceae) of Turkish origin were evaluated. Enzyme inhibitory activity of the extracts was tested in vitro...

This study was conducted to explore the tree species composition of the Khadimnagar National Park of Bangladesh, and also to assess its potential to conserve biodiversity. A total of 524 individual of 29 tree species belonging to 18 families were identified. The dominant family was Meliaceae,...

Plantations provide a micro-climate that can facilitate the regeneration of other forest species. Often exotic species have been tested for these kinds of functions. To determine the potential for indigenous trees as plantation species for their ability to foster forest species regeneration, this...

Dated phylogenies have helped clarify the complex history of many plant families that today are restricted to the world's tropical forests, but that have Eocene, Oligocene, and Miocene fossils from the northern hemisphere. One such family is the Meliaceae. Here we infer the history of the...

A study was conducted at two-biodiversity conservation areas of Northeastern Bangladesh (a part of Sylhet Forest Division) to assess the species composition, diversity and density of natural regeneration of tree species both indigenous and exotic species. Data were collected by stratified random...

Palynological investigation of ten samples obtained from a drill core belonging to the Late Pleistocene deposits of the PatanFormation in the Kathmandu Valley revealed 40 plant species belonging to 22 families. The gymnosperms are represented by Abies, Picea, Pinus spp. (P. roxburghii and P....

Use of synthetic pesticides in developing countries is not only limited by their being expensive but also the small (uneconomic) fields whose limited production costs cannot offset costs of agricultural implements like agro-chemicals. Subsistence farmers, therefore, have no choice but to use local...

An experiment was conducted during February-June 2006 to demonstrate the status and various uses of invasive alien plant species in and around Satchari National Park, in the northeastern hilly regions of Bangladesh. A total of 19 alien species belonging to 12 different families were recorded. The...
