Lichen is a symbiosis of fungi and algae cause morphology physiology are in one unit. It can be an indicator for environmental monitoring, especially as bioindicator air pollution, therefore deserves more attention the tropics. Data diversity distribution lichens Nusa Tenggara region still very lacking. Benang Stokel Waterfall Tourism has high potential center exploration that needs attention, ...
The Ruzizi River, the outlet of Lake Kivu in Albertine Rift, flows into Tanganyika and is important for hydropower generation irrigation. impacts 2 dams River on macroinvertebrate community composition diversity were surveyed every 3 months from December 2015 to October 2017. Macroinvertebrate samples collected at sites upstream downstream additionally two further dams, both comparatively prist...
Riparian vegetation on river borders can affect the riparian ecosystem of watershed related to its function as a buffer zone and ecotone between water land. A high diversity indicate that border is in good condition. Therefore, it helpful inventory zone, which was done this study using Shannon-Wiener index. In research, four plots measuring 5m x 5m, spread across upstream, middle, downstream ar...
Metro Cebu, Philippines has a history of over 800 years urbanization, making it unique location for urban ecological studies. Urbanization can have significant impact on floral communities, but the species composition and variety cemeteries in Cebu not been reported. We calculated richness (N), abundance (n), evenness (PE), diversity (H' D) by conducting first survey (local plants alien plants)...
Biodiversity is one of the important concepts in ecology and vegetation management, and plays an important role in the health, production, and evaluation of ecosystems. Species diversity is a major part of biodiversity and one of the most important parameters of ecosystem changes. In this research, the data of the rangeland evaluation different climate zones of Isfahan province were used in fiv...
Anthropogenic Biomes describe globally significant ecological patterns within the terrestrial biosphere caused by sustained direct human interaction with ecosystem, including agriculture, urbanization, forestry and other land uses. The present study focused on the invertebrate diversity in Marudhamalai Hills which is highly disturbed by human activities. Different techniques to identify the dis...
the study comparatively assessed the impacts of farm activities on the abundance and diversity of soil arthropods and soil physico-chemical parameters of the practical year training programme (pytp) farmlands, university of ibadan, south western nigeria. soil arthropods were collected from september, 2010 to february, 2011 in five sampling sites of pytp farmlands using berlese tullgren extracti...
knowledge about spatial soil variation in terms of measured pedodiversity offers the possibility to estimate the quality and variance within a soil map. diversity indices and abundance distribution models are statistical tools which ecologists have applied for decades for analyzing the intrinsic regularities of various ecological entities. in this study relationships between soils evolution, la...
background: there are nearly 1000 species of phlebotomine sand flies in 6 genera, of which only two, phlebotomus in the old world and lutzomyia in the new world are medically important. globally, leishmaniasis prevalent in 98 countries and affects estimated 12 million people with almost two million new cases per year. some rural areas of azarshahr district in east azarbaijan province have been ...
Present study was carried out during 2019 at the Vegetable Research Farm, Punjab Agricultural University, Ludhiana to generate information on diversity of invertebrates in okra. Study revealed that okra crop harboured by 27 invertebrate species belonging 11 orders and 26 families. Of these, maximum belonged order Hemiptera followed Coleoptera. Higher values Shannon-Wiener index (1.75, 1.84) Sim...
