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...

aim of this research was evaluated and compared of density (number tree per hectare), basal area and volume characteristics for estimation of tree species diversity in degraded forests. in order to, 73 hectares of kouhmian forests was inventory based on random systematic pattern with circular plots (10r and 26 plots). in each plot species, dbh and number of tree were measured and recorded. to e...

The ecological health of River Ringim, Jigawa State, northwestern Nigeria was assessed between November 2018 and March 2019. Key physico-chemical variables alongside macroinvertebrates assemblage were used to achieve the aim study. result showed that four stations sampled relatively perturbed judging from high values turbidity, nitrate, phosphate, BOD, TDS, EC. Twelve (12) taxa 365 individuals ...

Diversity represents a key concept in ecology, and there are various methods of assessing it. The multitude of diversity indices are quite puzzling and sometimes difficult to compute for a large volume of data. This paper promotes a computational tool used to assess the diversity of different entities. The BIODIV software is a user-friendly tool, developed using Microsoft Visual Basic. It is ca...

The types of plant diversity on the territory Radomyshl Forestry in areas with different forest vegetation conditions were investigated. 21 species belonging to 15 families and 18 genera have been identified. main are determined (Pinus sylvestris-Vaccinium vitisidaea+V. myrtillus-Cladonia spp.+ Pleurozium; Pinus sylvestris-Calluna vulgaris-Pleurozium+ Cladonia ssp.; myrtillus-Pleurozium; sylves...

Abstract The positive ecological interaction between gap formation and natural regeneration has been examined but little research carried out on the effects of gaps in forests under different intensities disturbance. This study evaluates composition, diversity, density abundance tree species undisturbed, intermittently disturbed, disturbed forest sites. Bia Tano Forest Reserve Ghana was area th...

Este estudo apresenta os resultados da diversidade de peixes em um trecho do Rio dos Bois, manancial Cerrado, localizado no noroeste Goiás, Brasil. Sendo importante tributário das cabeceiras rio Araguaia, bacia Araguaia-Tocantins, que possui importantes atributos na manutenção biota deste complexo ecossistema, e parte mosaico Cerrado. A região estudada, compreende a calha principal sua cabeceir...

Canals of Sundarbans in India are highly vulnerable to anthropogenic pressures which directly or indirectly impact the biological components such ecosystems. Being at base trophic pyramid, phytoplankton is exposed environmental stressors and will be reflected upper strata aquatic food chain. Hence, communities along with their interrelationship parameters were assessed Bhetkimari canal, a semi-...
