Biodiversity has an essential role in the stability of ecosystem. A high level biodiversity indicates a more stable and The decline quality ecosystems such as coral reefs, seagrass beds, mangrove forests due to anthropogenic factors global warming threaten biodiversity. This study aims determine diversity reef fish species using environmental DNA (eDNA) approach waters Mansinam Lemon, Manokwari...
Abstract The use of agrochemicals in agriculture may impact aquatic ecosystems, particularly influencing the stream insect communities. Among insects, family Chironomidae is most abundant and species-diverse group found freshwater ecosystems. However, southern hemisphere, studies with are still sparse, compared to Europe North America. present study evaluates responses species (Insecta: Diptera...
Lichen is a symbiosis of fungi and algae cause morphology physiology are in one unit. It can be an indicator for environmental monitoring, especially as bioindicator air pollution, therefore deserves more attention the tropics. Data diversity distribution lichens Nusa Tenggara region still very lacking. Benang Stokel Waterfall Tourism has high potential center exploration that needs attention, ...
The Mekong River mouth has a significance of biodiversity and biological resources, especially for the floating benthic communities in ecosystem. study area belongs to 4 provinces lower River: Tien Giang, Tra Vinh, Ben Tre, Soc Trang. results Shannon-Wiener value assessment Berger - Parke index 3 major aquatic including phytoplankton, zooplankton showing that at low levels terms species composi...
Riparian vegetation on river borders can affect the riparian ecosystem of watershed related to its function as a buffer zone and ecotone between water land. A high diversity indicate that border is in good condition. Therefore, it helpful inventory zone, which was done this study using Shannon-Wiener index. In research, four plots measuring 5m x 5m, spread across upstream, middle, downstream ar...
В статье рассматриваются проблемы изучения основных подходов к определению сущности информации, для чего анализируются основные работы выдающихся мыслителей, таких как Н. Винер, К. Шеннон и Г. Бейтсон, которые внесли значительный вклад в область теории информации. Проводится связь между информацией такими понятиями, энтропия, сложность негэнтропия. Рассмотрение этого материала предполагает выяв...
This study was carried out to determine the biodiversity and densities of Trichoptera larvae at stations in Kastamonu (Cide)-Sinop (Ayanc?k) coastal region. Benthic macroinvertebrate samples were collected from each 19 using kick-net sampling method with a D-frame net (500-?m mesh). Using data larvae, similarity, diversity, dominance population density relationships among habitats measured. Acc...
Both fertilizer and plant species richness may affect the soil nematode community. However, influence of weed interaction is unclear. Nematode abundance biodiversity in wheat plots treated with nitrogen, phosphate potassium addition (0, 1, 2 4 levels) were investigated a long-term microcosm experiment established 2010 at Kaifeng, China. The results demonstrated that treatment increased total ne...
It is now well known that a healthy urban ecosystem crucial element to healthier citizens (Astell-Burt and Feng 2019), better air (Ning et al. 2016) water quality (Livesley 2016), overall, more resilient environment (Huff 2020). With ecoTeka, an open-source platform for tree management, we leverage the power of OpenStreetMap (Mooney 2015), Mappilary, open data allow decision makers improve thei...
The intertidal zone is the area between highest and lowest tides, which represents transition from ocean conditions to land conditions. This study aimed determine diversity distribution of mollusks that exist along Nglambor Beach, August November 2020. Observations all molluscs were carried out at two random stations using 10 plots measuring 1 x m 2 with 5 meters. A total classes Mollusca (Gast...
