Indigenous vegetables of Nepal for biodiversity and food security
Nepal has great biodiversity, as a result of its extreme variations in altitude, ecology, farming systems and varied socio-cultural settings. In Nepal, about 200 plant species are consumed as vegetables. The aim of paper is to point out existing indigenous vegetables in Nepal and how these are utilized for food security and biodiversity conservation. Indigenous vegetables are considered valuable because of their ability...

Factors affecting the Luangwa (Zambia) hippo population dynamics within its carrying capacity band – Insights for better management
This study assessed factors regulating the Luangwa (Zambia) hippo population within the carrying capacity band along the 165 km stretch of the Luangwa River, Eastern Zambia. Objectives of the study were to 1) establish whether the hippo population had reached and remained within the carrying capacity band in the last 32 years, and 2) determine the influence on population size and density distribution of grass biomass...

Estimating suitable environments for invasive plant species across large landscapes: A remote sensing strategy using Landsat 7 ETM+
The key to reducing ecological and economic damage caused by invasive plant species is to locate and eradicate new invasions before they threaten native biodiversity and ecological processes. We used Landsat Enhanced Thematic Mapper Plus imagery to estimate suitable environments for four invasive plants in Big Bend National Park, southwest Texas, using a presence-only modeling approach. Giant reed (Arundo donax),...

A comparison of species richness of the true bugs (Hemiptera: Heteroptera) among four desert types in Kazakhstan
Kazakh insect fauna and biodiversity, especially in arid regions, are largely unknown. We identified species rich (252 species) Heteroptera assemblages associated with four desert types: sandy, solonchak (salt), clay and stony desert. The sandy desert was most species rich (153), followed by the solonchak desert (101), and clay desert (73). The stony desert was the poorest species (61). We found...

The impact of reducing emissions from deforestation and degradation (REDD) on forest-dependent livelihoods by gender in Tanzania and the role of the institutional framework for equitable benefits
Tanzania has been receiving significant funding from donor countries for the implementation of programmes to reduce emissions from deforestation and degradation (REDD). REDD is seen as an opportunity to enhance conservation and livelihoods. But what is the impact of REDD on gender? This is an area of inquiry that has not been critically looked into. This study was an attempt towards filling this...

Diversity of Collembola (Arthropoda: Hexapoda) across different types of vegetation in Brazil
The diversity of Collembola across three forest types was compared on the basis of species richness, abundance and species turnover. The goal of this study was to identify patterns of diversity at local scale in each forest type sample and to compare it at the regional scale. Our results showed that samples taken from the Atlantic Forest had higher α, β and γ diversity than those from Amazon Campinarana...
