PCR-denaturing gradient gel electrophoresis (DGGE) and canonical correspondence analysis (CCA) were used to explore the relationship between eukaryotic plankton community succession and environmental factors in two aquaculture pond models with gibel carp Carassius auratus gibelio. The main culture species of pond 1 were gibel carp and grass carp, and the combined density was 46224 fingerling/ha...

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...

The Lo Go-Xa Mat is a national park in the southeastern region of Vietnam, which has a particularly high biodiversity and it includes different wetlands which are unique diverse in species composition. It can be categorized into two types: temporarily-seasonally and permanently flooded wetlands. Ta Not grassy marsh is representative of the seasonally flooded wetland. Whilst the diversity and ec...

The purpose of this study was to determine the diversity sea urchin species on Kadahang Beach, East Sumba Regency. sampling technique used is a purposive and analyzed using quantitative descriptive approach with Shannon-Wiener index formula. Sea samples were calculated quadratic transect plot size 1 x meter placed perpendicular inside 50 meters 16 plots. environmental factors measured temperatu...

In the study, International Waterbird Census (IWC) conducted in 2021 wetlands with different habitat characteristics around Dardanelles were evaluated. 3086 individuals belonging to 30 waterbird species counted Kavak Delta, 31 and 1150 Çardak Lagoon, 22 3906 Gökçeada Salt Lake, 11 289 Suvla Lake 8 84 Uzunhızırlı Pond. The highest diversity (Shannon-Wiener Indices, H: 2,473) richness (Margalef I...

Weeding and fertilization are important farming practices. Integrated weed management should protect or improve the biodiversity of farmland weed communities for a better ecological environment with not only increased crop yield, but also reduced use of herbicides. This study hypothesized that appropriate fertilization would benefit both crop growth and the biodiversity of farmland weed communi...

The microalgae community structure in an aquatic ecosystem is strongly influenced by environmental factors. One of the rivers Indonesia, located inhe island Lombok, West Nusa Tenggara, Jangkok River. River widely used residents for activities, including industry, cultivation, waste disposal, and others. This study aimed to determine research was carried out with exploration descriptive method q...

Recent experimental and theoretical investigations have made considerable advances in three major areas relating to the structural basis of quantitative cortical microcircuit theory. The first concerns the nature of the cellular units, encompassing the increasingly precise identification and progressively more complete listing of the individual cellular species that constitute the various corti...
