Totalai Game Reserve has a peculiar combination of avian fauna. A survevy of avian fauna at Totalai Game Reserve was conducted during November to April (2012-2013). In this […]
Impact of crude oil pollution on the physicochemical and microbiological properties of orashi river wetland in Egbema, Nigeria
The study investigated impact of crude oil pollution on the physicochemical and microbiological parameters of crude oil polluted Orashi River wetland. The physicochemical, microbiological parameters and trend of enzymatic activities in crude oil polluted and unpolluted wetlands were evaluated. Bioloads had their highest values in the lightly polluted wetlands with values of rainy season leading, […]
Field observations of shallow-water sea cucumbers in Gulf of Thailand and Andaman Sea
This study aims to investigate the species presence and distribution of sea cucumbers in the main habitats of coral reefs, sea grass beds, rocky shores and sandy shores in the Gulf of Thailand and Andaman Sea during May 2009 to March 2010. Results showed that a total of 21 sea cucumber species from 5 families […]
Effect of explants, salts concentration medium and hormone treatments on Taxus baccata in vitro culture
Taxus baccata is an endangered forest tree species with low regeneration. The highest Callus induction (96.67%) was occurred on ½ MS medium which had one-fourth nitrogen (KNO3, NH4NO3) supplemented with glutamine, 1 mg/l 2,4-D and 1 mg/l Kin from stem. The maximum callus size (80.67 mm2) was obtained from leaf culture on ½ MS medium […]
Comparison of butterfly diversity in natural and regenerating forest in a biodiversity conservation site at maragamuwa, Sri Lanka
Knowledge of species composition and diversity of butterflies offers great benefits for nature conservation and environmental monitoring. Butterfly species richness and diversity were studied at a biodiversity conservation site at Maragamuwa, Sri Lanka from July 2009 to February 2010 using the fixed distance line transect method. A total of 4968 butterflies belonging to the super […]
Diversity of cave macro-invertebrates in mighty cave, tagoloan, lanao del norte, Philippines
Macro-invertebrates help maintain the stability of the wide niches of faunal assemblage of caves. This study was conducted to determine the diversity and relative abundance of macro-invertebrates in the recently-explored Mighty Cave in Tagoloan, Lanao del Norte. Sampling was conducted using hand-searching, direct counting and pitfall trap methods in four cave zones. Ten species of […]
Predation potential of foliage spiders and estimates of utilization curve, niche breadth and overlap in cotton filed from Punjab, Pakistan
Production of cotton is restricted by pest infestation causing deterioration in lint quality. Spiders being generalist predators regulate insect populations. Bio diversity and relative abundance of spiders as predator as well as feeding niches of nine co existing spider species in cotton were computed and compared for the niche breadth; niche and specific overlaps. A […]
Early growth stages structure and distribution of Pericopsis elata (Harms) van Meeuven in a logging concession of South – East Cameroon
Pericopsis elata (Harms) van Meeuwen is a tropical Africa’s timber of high economic value. In many countries its low natural regeneration rate does not favor the replacement of harvested populations, thus CITES and IUCN recommended a total protection of the species. This survey aimed to characterize the early growth stages and natural regeneration of P. […]
Diversity of butterflies (Order: Lepidoptera) in assam university campus and its vicinity, cachar district, assam, India
A preliminary study on the diversity of butterflies was carried out in Assam University campus and its vicinity, Cachar district, Assam, India from June 2013 to May 2014 using transects lining method (Barhaum et al., 1980). The University Campus is surrounded by lush green hillocks, natural lakes and the picturesque tea gardens of South Assam. […]
Comparison of growth forms and life forms of rangeland plants under different methods of rangeland management (case study: rangelands around Bojnourd city)
Planning and optimal management of rangelands is important to achieve to vegetation changes in enclosure and enclosure rangelands. In this study due to the lack of sufficient research was compared the effect of each of the four methods of rangeland management on the plant composition. The study area located in the rangelands around the Bojnourd […]
