Species diversity is a crucial index used to evaluate the stability and complexity of forest ecosystems. Studying relationship between stand structure understory herbaceous plants species useful for managers formulate best optimization method with goal improving diversity. In this research, Platycladus orientalis plantations in Beijing were taken as research object. Pearson’s correlation analys...

Grasslands in the Altay Mountains are main part of grassland ecosystem Xinjiang, and spatial distribution patterns species diversity biomass have changed significantly due to combined effects climate change anthropogenic disturbances. To clarify point factors on biomass, this study investigated vegetation status 41 sample plots grasslands forest area. The Margalef richness index, Simpson domina...

Abstract Background Wetlands are transition zones between aquatic and terrestrial environments of Opa Reservoir Obafemi Awolowo University, Ile-Ife, Nigeria, threatened by increase in agricultural practices urbanization within the catchment area. A critical appraisal current ecological integrity wetlands using planktonic composition community structure which formidable to sustaining is essentia...

Modification and degradation of habitats outside the boundaries a national parkmay result in park's integrity being compromised. Thus, present study aims todocument variation freshwater fish water quality tropical forest streams adjacent to western boundary Kinabalu Park, Sabah. Concurrently, samplesand environmental parameters were collected at six stations covering total streamline length 10 ...

This study was carried out from December 2018 to November 2019 examine the distribution and abundance of harmful algal species (HAS) in central Bonny estuary. Seven sampling stations were established with ArcGIS tool. Microalgae sampled 20 mm mesh plankton net. Nutrients analyzed laboratory using APHA 4500 Method, while physicochemical characteristics determined situ. Results revealed that envi...

Glacier-fed streams are one of the environments most sensitive to global climate change. However, effects freezing–thawing process on benthic macroinvertebrate communities in different habitats glacier-fed unclear. In this paper, we investigated macroinvertebrates riffles and pools a stream Xinjiang, China, during pre-freezing period (November, 2018), freezing (January 2019), thawing (April, 20...
