Traditional measures of diversity, namely the number of species as well as Simpson's and Shannon's indices, are particular cases of Tsallis entropy. Entropy decomposition, i.e. decomposing gamma entropy into alpha and beta components, has been previously derived in the literature. We propose a generalization of the additive decomposition of Shannon entropy applied to Tsallis entropy. We obtain ...

Preserving biodiversity and ecosystem stability is a challenge that can be pursued through modern statistical mechanics modeling. Environmental changes and human activity threaten the fauna of many geographical areas. We exploit the entropy definition from thermodynamics to assess ecosystem stability. In particular, we study a minimal ecosystem on a lattice in which two species struggle for sur...

Anaerobic digestion (AD) is one of the few sustainable technologies that both produce energy and treat waste streams. Driven by a complex and diverse community of microbes, AD may be affected by different factors, many of which also influence the composition and activity of the microbial community. In this study, the biodiversity of microbial populations in innovative mesophilic/thermophilic te...

The threat of invasion is growing globally and endangers biodiversity. Exotic invasive plants are putting a harm to the vegetation Pakistan’s Pothwar region, which biodiversity hotspot. In current study, effects Broussonetia papyrifera , Parthenium hysterophorus, Xanthium strumarium Lantana camara on local flora in area were examined. Two categorical groups (invaded non-invaded) used dichotomiz...

Budiharta S (2010) Floristic composition at biodiversity protection area in Lubuk Kakap, District of Ketapang, West Kalimantan. Biodiversitas 11: 151-156. A study on floristic composition has been conducted at biodiversity protection area (Kawasan Perlindungan Plasma Nutfah, KPPN) of PT. Suka Jaya Makmur in Lubuk Kakap, District of Ketapang, West Kalimantan. Two sampling methods were used: Poin...

This study investigated the biodiversity, phylogeny, and antifungal activity of endophytic fungi isolated from Zanthoxylum bungeanum. A total of 940 isolates obtained were grouped into 93 morphotypes, 43 species, and 23 genera, which were authenticated by molecular identification based on rDNA internal transcribed spacer (ITS) sequence analysis. A high diversity of endophytic fungi from Z. bung...

BACKGROUND/OBJECTIVES The use of emollients is widely recommended for the management of atopic dermatitis (AD), especially between flares. An imbalance of skin microflora is suspected of playing a key role in exacerbations of AD. Our aim was to evaluate the effect of a new emollient balm on clinical parameters (SCORing Atopic Dermatitis [SCORAD], xerosis, pruritus), skin barrier function (trans...

Comparative study has been done to examine the biodiversity and ecological status of the intertidal region of Tata Institute of Fundamental Research (TIFR), Bandstand and National Centre for Performing Arts (NCPA) rocky beaches in Mumbai, West coast of India. A total of 50 species of intertidal organisms were recorded from these shores. Shannon and Simpson's diversity index, Margalefs richness ...

The tree layer vegetation of two protected ecosystems i.e. Similipal Biosphere Reserve (SBR) and Bhitarkanika National Park (BNP) of eastern ghat was analysed for structure, composition and diversity. With respect to the tree species composition the two protected ecosystems were differed from each other at the family, genera and species level. About 117 tree species representing 85 genera and 4...

Urban grasslands, landscapes dominated by turfgrasses for aesthetic or recreational groundcovers, are rapidly expanding in the United States and globally. These managed ecosystems are often less diverse than the natural or agricultural lands they replace, leading to potential losses in ecosystem functioning. Research in non-urban systems has provided evidence for increases in multiple ecosystem...
