Background: This study focused on evaluating the diversity and richness of edaphic macrofauna in eight banana farms western zone Nicaragua. Methods: The sampling design was random descriptive, it divided into two phases, first collection sample, second classification, coding, storage extracted populations. Subsequently, indices spe...
To overcome sinking, plankton have devised various types of strategies. One is swimming, that is, an active, energy-consuming self-propulsion than can oppose gravitational sinking. Other phytoplankters can modify their buoyancy, becoming, at least for some time, positively buoyant. Others can exploit the turbulence in the mixed layer, using it to stay suspended for longer times. This latter opt...
This study sought to clarify the composition of soil fungal and bacterial communities along an elevation gradient in arid montane ecosystem as well influence environmental factors (soil properties, climate, topography, plant diversity) upon microbial community structures. Four vegetation types—montane desert steppe (mean elevation: 1761 m), shrub 2077 subalpine coniferous forest 2485 2903 m)—we...
In most ecosystems, disturbance is an important agent of variation in community structure and composition. Determining the diversity and composition of soil seed bank is essential for designing conservation and restoration programs because it can markedly contribute to future plant communities. Despite the important role of soil seed banks in the composition of different plant communities, and...
Information of vegetation structure and composition terrestrial flora biodiversity can be measured by analysis method. The method requires sampling plots as a measurement plot capable to describe species in forest stand. distribution diversity, especially plants, is relatively dependent on the type plant with condition area it occupies. Therefore, an efficient representative needed for ecosyste...
Climate change is known to have significant impacts on coastal marine ecosystems. However, a good understanding of the exact requires consistent long-term monitoring programs, which are not available for many The Hudson River Estuary (HRE) provides critical habitats estuarine, freshwater, and diadromous species. Longitudinal Ichthyoplankton Survey Water Quality in Biological Monitoring Program ...
The regular assessment of faunal diversity near the energy power plant has gained interest many researchers. activity and effluent discharged from have remarkably stressed adjacent assemblage alpha biotic community surrounding plant. Hence, this study aimed to assess fishes benthos in bordering areas Tanjung Kidurong Combined Cycle Power Plant (TKCCP), Bintulu Sarawak. investigation was conduct...
