Insect diversity is believed to be used as a bio-indicator of spring quality, this study aimed at determining the insect around Mutis Timau Nature Reserve. The was conducted from June August 2019. Insects were caught by using yellow pan trap and hand sorting. insects determined based on Shannon-Wiener index (H'), species richness (R1), dominance (D), evenness (E). results showed that 16 belong ...

Conserving aquatic ecosystems requires efficient tools to accurately assess the biodiversity of species. However, existing knowledge is insufficient in terms reliability and comparability methods measuring fish diversity. Environmental DNA (eDNA), as a promising method, was used detect taxa this study. We optimized eDNA method laboratory, applied optimal survey diversity natural life reserve. s...

Understanding ecosystem development of post-mining areas requires observing the plant and microbial communities. It is widely known that mutual interaction important for both these groups, benefit significantly. The aim this study was to broaden knowledge about relation between vegetation functional diversity bacterial communities in novel ecosystems discuss potential applicability methods stud...

Many bird species depend on wetlands and the surrounding habitats. However, status of these wetlands, as well their biodiversity, is poorly understood maintained. From January to February 2021, we assessed compositions, relative abundances, distributions throughout five wetland habitats in East Gojjam zone. In each study site, systematic random sampling techniques were applied at a 4 km interva...

The Atlantic Forest is one of the richest and most threatened biomes in Brazil. However, structure floristic composition many its remnants are still unknown. This study assessed tree Serra da Tiririca – SET coastal remnant, largest remnant State Park PESET (Atlantic Forest, RJ). In ten 50 × 20 m plots installed between edges interior we registered 403 trees distributed 29 families, 59 genera, 1...

The aim of this study was to determine the dynamics of colonisation and composition of the wood-decomposer community in a native forest and four monocultures over time. A fingerprinting method of TGGE (temperature gradient gel electrophoresis) with rDNA amplified by ITS1F and ITS2 primer pairs was optimized and used as a culture-independent approach to determine the dominant fungal species and ...

An experiment was conducted to manage the eggplant (brinjal) shoot and fruit borer Leucinodes orbonalis Guenée (Lepidoptera: Crambidae), the leafhopper Amrasca biguttula biguttula (Ishida) (Hemiptera: Cicadellidae), and the whitefly Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) during kharif, the southwest monsoon season (Jul-Oct), in 2010 and 2011 at an experimental farm at the Division ...

The spatial distribution of 50 ornamental fish species from shallow water habitats on coral reefs were investigated using visual census techniques, between latitudes 11-29°N in the Red Sea, in Jordan, Egypt, Saudi Arabia, and Yemen, and in the adjacent Gulf of Aden in Djibouti. One hundred eighteen transects (each 100×5 m) were examined in 29 sites (3-8 sites per country). A total of 522,523 fi...

AIMS Considered as an essential measure in the application of soil seed bank (SSB) projects, the mixing of substrate and surface soil can effectively improve soil condition. This research is aimed at exploring the diversity characteristics of SSBs and the relationships between SSBs and soil properties. METHODS Canonical correspondence analysis (CCA) was adopted to describe the ordination of S...

the unitary cayley graph xn has vertex set zn = {0, 1,…, n-1} and vertices u and v areadjacent, if gcd(uv, n) = 1. in [a. ilić, the energy of unitary cayley graphs, linear algebraappl. 431 (2009) 1881–1889], the energy of unitary cayley graphs is computed. in this paperthe wiener and hyperwiener index of xn is computed.
