The 2020 COVID-19 pandemic and the resulting national international movement restrictions provide a unique opportunity to investigate consequences of changing anthropogenic noise regimes on animal communities soundscapes. Here, I used this lockdown period as natural experiment changes soundscape intensity, structure, dynamics during restricted human activity (lockdown) in suburban Nottingham, U...

1. The structure of lotic macroinvertebrate communities may be strongly influenced by land-use practices within catchments. However, the relative magnitude of influence on the benthos may depend upon the spatial arrangement of different land uses in the catchment. 2. We examined the influence of land-cover patterns on in-stream physico-chemical features and macroinvertebrate assemblages in nine...

The influence of soil pH was evaluated on the abundance and generic diversity of cyanobacteria in soil samples collected from diverse rice soil ecologies of India. Qualitative and quantitative studies of the 52 soil samples collected from nine agroecologies was carried out using enrichment, MPN (Most Probable Number) techniques and diversity indices were measured. A total of 166 forms, includin...

Using a combination of observational and questionnaire methods, this longitudinal study investigated interracial contact in a university residence dining hall, focusing on the organization of seating patterns. The results showed that informal division by race was extensive, with indices of interaction (xPy*) and evenness (D) indicating the existence of high levels of racial segregation. Moreove...

Abstract. Aim. The author has developed a criterion to test the hypothesis of uniform distribution for random variable observations in small samples. is built by using sample construct variation series ascending order and dividing each previous term this extreme term, then discarding it. resulting new processed similarly until there only one quotient left that value. Methods. paper uses methods...

Evenness is a key measure of community structure. Here, we examine the relationship between evenness and size-abundance distributions for both individuals and species using data gathered from Amazonian fish assemblages. We show that evenness increases as the fraction of numerically abundant species in larger body-size classes rises. As any processes that enable larger bodied species to increase...

The aim of this study was to evaluate the biodiversity ofplant associations in On Ebn-e-Ali Mountain in Tabriz and its relationship to various biodiversity indices. Four plant associations including 1) Noaea mucronata- Poetum bulbosa, 2) Noaea mucronata- Brometum tomentellus, 3) related to bush form as well as Poeto bulbosa-Brometum tomentellus and4) Brometo ...

The study was conducted to assess the native and alien plant species in one of the highly disturbed forest (S1) and less disturbed forest (S2) in Mt. Manunggal, Cebu Island, Philippines. Twenty-four quadrats with a size of 20mx20 m were established using a quadrat sampling technique to identify and record all plant species. Diversity indices were utilized to determine species abundance, richnes...
