Reservoirs are significant sources of greenhouse gases (GHG), such as carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O), to the atmosphere. These systems receive metabolize a larger amount organic inorganic nitrogen from their watersheds than lakes, resulting in production CO2, CH4 N2O. Despite global relevance, there still important uncertainties regarding magnitude, variability driv...

Including or excluding rare taxa in bioassessment is a controversial topic, which essentially affects the reliability and accuracy of the result. In the present paper, we hypothesize that biological indices such as Shannon-Wiener index, Simpson's index, Margalef index, evenness, BMWP (biological monitoring working party), and ASPT (Average Score Per Taxon) respond differently to rare taxa exclu...

We give a complete description of degenerations $3$-dimensional nilpotent algebras, $4$-dimensional commutative algebras and $5$-dimensional anticommutative over $ \mathbb C$. In particular, we correct several mistakes from the paper `Contractions low-dimensional Jordan algebras' by Ancochea Berm\'{u}dez, Fres\'{a}n Margalef Bentabol.

in this study, species richness, evenness and vegetation biodiversity were investigated in stabilized and non-stabilized cut edge areas of chachkam district forest roads in sari forest of iran. 18 micro plots 1×1m (36 micro plots) were sampled to carry out this research on two cut edge areas. number of trees, shrubs and herbaceous were recorded in each micro-plot. significant difference was inv...

Here, I address two other problems raised by this article. A review of published experimental results led the authors to conclude that “diversity enhanced ecosystem stability”, where this is defined as “the ability to withstand recurrent perturbations”. This curious statement reverses modern theory of ecological diversity in the ocean as discussed, for instance, by Ramón Margalef. Ecosystems of...

Seven major ecological zones of Nigeria with modern functional apiaries were mapped and sampled in the rainy season between April 2016 October 2018 for estimating bee foraging flight range floral species diversity; collating satellite imagery data geospatial zone mapping using GPS (Garmin Etrex 20) to capture coordinates locations their attributes, climatic topographic generating zones: wetland...

Spiders are recorded as indigenous natural enemies of tea mosquito bug (Helopeltis spp.), which is one of the major economically important pests of cashew. Consecutive survey for three years revealed occurrence of 117 species of spiders belonging to 18 families viz., Araneidae, Clubionidae, Corinnidae, Gnaphosidae, Hersilidae, Linyphiidae, Lycosidae, Miturgidae, Nephilidae, Oxyopidae, Pholcidae...
