BACKGROUND Rotaviral diarrhea (RD) has been associated with the biodiversity of the fecal microbiota in infants; however, the differences in the biodiversity of the fecal microbiota between infants with RD and healthy (H) infants have not been clearly elucidated. OBJECTIVES This study aimed to reveal the changes in the biodiversity of the fecal microbiota of infants with RD. PATIENTS AND ME...

Having the richest plants biodiversity, Hyrcanian natural mixed-beech forests contribute to the huge carbon pool in the different soil layers. This research aims to develop modeling soil carbon sequestration in terms of the plant biodiversity indices to manage soil carbon stock with respect to trend of sustainability, fertility, carbon cycle, and planning to face with climate change in local/ r...

Biodiversity is important in maintaining ecosystem viability, and the availability of adequate biodiversity data is a prerequisite for the sustainable management of natural resources. As such, there is a clear need to map biodiversity at high spatial resolutions across large areas. Airborne and spaceborne optical remote sensing is a potential tool to provide such biodiversity data. The spectral...

Independently owned nature reserves are proliferating across the developing world. Nevertheless, the conservation community knows practically nothing about them. This paper examines the economic, ecological, and social impacts of ecotourism, as evidenced at thirty-two of these reserves. Ecotourism is shown to be the primary means through which reserves survive financially. This reliance provide...

The economic importance and uses of the large number of plant species of India make it essential for their biodiversity to be conserved. In order to undertake the steps for biodiversity conservation such as identiication of species and monitoring of climatic conditions, it is essential to eeciently manage the vast amount of biodiversity related data. This data includes taxonomic data, geographi...

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: Anthropogenic impacts on the environment often result in loss of biodiversity. However, the effects of different parameters (such as soil pH) on biodiversity, which can be influenced by human activities, are poorly investigated on a global scale. The paper at hand proposes an approach to examine the relationship between biodiversity and several parameters, which can be anthropogenic...

Forest ecosystems play multiple important roles in meeting the habitat needs of different organisms and providing a variety services to humans. Biodiversity is one structural features dynamic complex forest ecosystems. One most challenging issues assessing understanding relationship between biodiversity environmental factors. The aim this study was investigate effect biotic abiotic factors on t...

MOTIVATION Rich collections of biodiversity information such as spatial distributions, species descriptions and trait data are now synthesized in publicly available online sources such as GBIF. Also phylogenetic knowledge now provides a sound understanding of the origin of organisms and their place in the tree of life. We demonstrate with PhyloJIVE that any phylogenetic tree can be linked to on...
