Effect of pre-sowing treatments on seed germination in Quercus serrata Thunb. and Quercus semecarpifolia Sm.

Quercus species are major forest forming species and helps in sustaining an ecosystem. Natural regeneration of these species is very poor due to various biological and physical factors. The present study was conducted to evaluate the effect of different pre-sowing treatments (scarification and cold- stratification) on seed germination of two Quercus species, that is, Quercus serrata (deciduous) and Quercus...

Among and within population variation in growth dynamics and floral sex ratios in Inula racemosa; a critically endangered medicinal herb of N. W. Himalayas

The purpose of the present study was to determine the extent to which different morphological and reproductive characteristics of a critically endangered, Himalayan herb (Inula racemosa) varied along an altitudinal gradient. To this end, seven populations growing at different altitudes (1595 - 2800 m asl) across the Kashmir Himalaya were assessed. ANOVA expressed significant differences (P=0.05) in all growth parameters...

Impact of the invasive shrub, Lantana camara L. on soil properties in Nairobi National Park, Kenya

Lantana camara L. (Verbenaceae) is an invasive shrub of global significance in the conservation of biodiversity in terrestrial ecosystems. The invasive species has profound impact on soil ecosystems due to its allelopathic and litter accumulation effect. This study tested for its impact on soil properties in Nairobi National Park (NNP) by randomly sampling soil from the invaded and un-invaded sites in three habitats...

Studies on floristic diversity of an organic farm of Himachal Pradesh, India: Transformation of a barren land to a productive niche

The ecological aspects pertaining to floral diversity, cropping systems and crop diversification of an organic farm CSKHPKV, Palampur were studied. The data for two years, that is, 2006-07 and 2007-08 was analyzed. The initial recorded data pertaining to various activities in the organic farm before 2006-07 showed low fertility soil status, very low productivity and least biodiversity in a so called barren land before...

Physico-chemical factors affecting the distribution of wetland birds of Barna Reservoir in Narmada Basin, Central India

The ecology of wetland birds of the Barna Reservoir was studied from March 2009 to February 2011. Species composition, diversity and abundance of birds were assessed. Sixty four (64) species of wetland birds were enumerated. Fourteen (14) environmental variables were correlated with the wetland birds species richness among which most of the variables were positively correlated with bird species richness except water...

Community organization, ecological distribution and diversity of trees and shrubs in selected areas of Branwar Forest of Kashmir Himalaya

Periodic studies were conducted in four selected sites of Branwar foresfiet area of Kashmir Himalaya in the year 2010 to 2011 for assessing ecological distribution and diversity of trees and shrubs. The Plant Community Organizational features, ecological distribution and diversity of different study sites in the Branwar Forest during 2010 to 2011 are markedly variable with regard to the life-forms namely, trees and...

Influence of insecticide treatment on ant diversity in tropical agroforestry system: Some aspect of the recolonization process

In order to assess the influence of insecticides treatment on ant diversity and recolonization processes in cocoa based agroforestry systems, sampling was performed using chemical knock-down technique during two consecutive cocoa campaigns (2006 and 2007) in six smallholding cocoa farms located in tree localities of the Centre Region of Cameroon. These localities are located along the South-North agroecological...

Potential impacts of recent climate change on biological control agents in agro-ecosystem: A review

Global climate change is a change in the long-term weather patterns that characterize the regions of the world. It is evident from increase in global average temperature, changes in the rainfall pattern and extreme climatic events. The impacts of warming can already be observed in many places, from rising sea levels to melting snow and ice to changing weather patterns. Climate change is already affecting...
