Abstract:
Natural variability in diversity of benthic macro invertebrate fauna or benthos has become a valuable tool in assessing, modeling and monitoring of water quality of inland water body with respect to its portability and of pollution level. However, inappropriate use of these indices may leads to false interpretation or prediction of behavior of inland water body. In this study we have employed two normalizing (i.e Shannon-Wiener Index (H’), Pielou´s Evenness (J’)) and one probability type (HurlbertPIE Index (PIE)) indices to evaluate behavior of Baikona tank water body between Jan-2008 to Dec 2

Abstract:
Abstract To find effective measures to control the water quality of the Hongmen Reservoir, it is necessary to better understand its phytoplankton composition, abundance and spatial and temporal distribution. Samples were collected at three sampling sites in January (dry season), May (wet season) and September (normal season) in 2019. Trophic level and stability status were assessed on the basis of the Shannon diversity index (H), species richness (S) and evenness (J) index. The different relationships between phytoplankton and the concentrations of several physicochemical parameters and the ma

Abstract:
The diversity of fishes along Buguey Lagoon remains underrepresented in research and conservation efforts. This study generally aimed to assess the diversity and document the species richness of fishes. Specifically, the study was conducted to determine diversity indices, IUCN status, and to generate a database for policy formulation towards the conservation of species and its management. Results of the study showed significant differences in fish diversity index in terms of Shannon–Weinner index, Simpson’s Reciprocal Index (1/D), Margalef’s diversity index (d), and Berger-Pa

The purpose of the study was to document and measure the richness, abundance, and diversity of the reptile in this district. Data was collected randomly in these habitats of this district using quadrat, visual encounter, and opportunistic survey methods. For 100 quadrates for each site seasonally, 20 quadrats were placed in each habitat along 5 transects. In total, 554 individual species belonging t

Abstract:
Butterflies are considered indicator species for conservation planning and environmental monitoring as their diversity and abundance are visibly affected by anthropogenic activities. In this study, the diversity and abundance of butterfly fauna in the surrounding vegetation of Rabindra Sarobar, Kolkata, India was assessed to provide baseline information on the size of species richness and prospective utilization in urban planning and conservation. A total of 64 butterfly species under 5 families and 44 genera were recorded over a period of ten months from June 2023 to March 2024. Family Nympha

This study determines the role of FUNAAB zoo park Abeokuta, Ogun State in tree biodiversity conservation and carbon sequestration of Abeokuta city in Nigeria. A systematic sampling approach was used and the tree biodiversity inventory was conducted. Accordingly, the study identified 30 plant species and 15 families with <em>Fabaceae</em> as the dominant family (6 species).&nbsp; Shannon diversity index (H&prime;) was 3.29 and Pielou&#39;s evenness (J&#39;) was 0.97 in the park. There were more native woody species (80%) than exotic (20%) in the park. Tree species were the dominant growth form

Butterflies are the indicator species as their diversity and abundance represent the health of a habitat and act as a tool for monitoring the impact of urbanization in an area. The aim of the present research paper is to estimate the diversity and abundance of butterfly fauna in the surrounding vegetation of Subhas Sarobar, Kolkata, India. The present study recorded 74 butterfly species of 5 families and 56 genera, which were sampled over a period of nine months from June 2023 to February 2024. Out of 74 species, 16 species belong to family Nymphalidae, 17 species to Lycaenidae, 3 species to P

Abstract:
The present study examines the relationships between structure (floristic composition, dendrometric parameters), diversity (diversity and evenness indexes) of urban forest park stands and the ecological (soil fertility, soil moisture), environmental factors (air pollution). The study is based on the forest park stands inventory data, performed from 2012 to 2017 in Kryvyi Rih City, Central Ukraine. The floristic compositions of the urban forest park stands are poor. There are only 23 species that belong to 14 families and 12 genera. More families were represented by at least more than 2% of tax
