Genetic variation in critically endangered plant Amsonia orientalis Decne

Amsonia orientalis Decne. (Apocynaceae) is a medical plant which has very restricted distribution only in west of Turkey and east of Greece on the world. Because of containing various alkaloids this species has anticancerogenic and antitumour effects. RAPD-PCR and SDS-PAGE were used to investigate the pattern of genetic variation among four known natural populations of […]

Preliminary survey of freshwater fishes from acid soil area in upstream of Bangpakong River, Nakhon Nayok Province, Thailand

Species diversity and distribution pattern of freshwater fishes from Nakhon Nayok Province, acid soil area in upstream of Bangpakong River, east of Thailand, were investigated in relation to environmental conditions between September-October 2012. The freshwater fishes samples and environmental factors were collected monthly, at 3 sampling stations. A total of 23 species, 8 families and […]

Effects of micro-catchment rain water-harvesting on survival and growth of multipurpose trees and Shrubs in Nyando District, Western Kenya

The productivity potential of dry lands is usually low hence normal crop production is usually next to impossible. This places greater value on the perennial vegetation, especially multipurpose trees and shrubs which too require some form of water management. Sesbania sesban, Gliricidia sepium, Casuarina equisetifolia, Grevillea robusta and Eucalyptus grandis seedlings were planted on micro-basins, […]

An anatomical investigation on Asteraceae family at Rajshahi Division, Bangladesh

Anatomical (especially stomata and trichome) investigation of the family Asteraceae (Compositae) growing throughout the Rajshahi Division situated in the northern part of Bangladesh was carried out. A total of 36 species under 29 genera of the family Asteraceae were collected and identified. Among the recorded species, both anomocytic and anisocytic stomata were found in 21 […]

Productivity of farmer-preferred maize varieties intercropped with beans in semi-arid Kenya

Farmers in the semi-arid regions grow drought tolerant maize varieties and practice maize-legume intercropping. A study was conducted in Machakos, Mwea and Waruhiu in 2008 short rains and 2009 long rains to determine the performance of maize varieties currently grown in semi-arid regions and their compatibility with beans. Sixteen maize varieties were grown as sole […]

Karyotype analysis and meiosis in Coryphosima stenoptera producta (Walker) and Chirista compta (Walker) (Orthoptera: Acrididae: Acridinae) from Cameroon

This article describes the hitherto unknown karyotypes of the short-horned grasshoppers Coryphosima stenoptera producta (Walker) and Chirista compta (Walker) that belong to the family Acrididae and subfamily Acridinae of the order Orthoptera. Chromosomes smears prepared by the lactic-propionic-orcein squash technique and chromosome analysis performed in the two species revealed a conserved karyotype of 2N= 23, […]

Phytosociological and ethnobotanical attributes of Skimmia laureola

Skmmia laureola grow gregariously in shady forest at altitude ranging from 7000 to 8800 feet. Leaves are also used as coughs remedy and commercially harvested as flavoring agent in food, and in traditional healing. These are made into garlands and considered sacred culture practices. Smoke from the leaves and twig is considered demon repellent. The […]

Statistical analysis for the assessment of water treatment parameters by three macrophytes identified

The lagooning floating process is an extensive treatment of wastewater. The study conducted on the campus of Abomey for phytopurification had the ambition to estimate models of evolution of the monitoring parameters: temperature, electrical conductivity, redox potential, hydrogen potential, dissolved oxygen, turbidity, after introduction of floating species Eichhornia crassipes Mart. Solms-Laub. (Water hyacinth), Pistia stratiotes […]
