One hundred and five grape samples were collected during two consecutive years from 33 locations on seven oceanic islands of the Azores Archipelago. Grape samples were obtained from vineyards that were either abandoned or under regular cultivation involving common viticultural interventions, to evaluate the impact of regular human intervention on grape yeast biota diversity in vineyards. A tota...

Hyperspectral images represent an important source of information to assess ecosystem biodiversity. In particular, plant species richness is a primary indicator of biodiversity. This paper uses spectral variance to predict vegetation richness, known as Spectral Variation Hypothesis. Hierarchical agglomerative clustering is our primary tool to retrieve clusters whose Shannon entropy should refle...

the purpose of this study was to investigate the distribution and biodiversity of diatoms during different seasons and their correlation with water quality parameters in helleh river estuary, bushehr, persian gulf. samples were taken in mid-season from summer 2011 to spring 2012 during a one-year period from different stations. results showed that diatoms mostly comprised of bacillariophyceae, ...

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 ...

two different microhabitats (cropped fields versus established date-palm farms) in two different cities in khuzestan province, southwestern iran, were sampled monthly during 2011-2012 in order to assess the role of anthropic uses of soil on the biodiversity of oribatid mites. a total of 17 species of oribatid mites belonging to 10 families and 15 genera were identified (nine species were collec...

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...

Ecological interactions between aboveground and belowground biodiversity have received many attentions in the recent decades. Although soil biodiversity declined with the decrease of plant diversity, many previous studies found plant species identities were more important than plant diversity in controlling soil biodiversity. This study focused on the responses of soil biodiversity to the alter...

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...

Aquatic macroinvertebrates, which play a significant role in the food chain of an ecosystem, are used in fresh water quality assessment to identify the environmental stress resulting from a variety of anthropogenic disturbances. Seasonal surveys of macroinvertebrate communities were conducted from April 2013 to March 2014 in Chhariganga oxbow lake of Nadia District of West Bengal, an eastern st...
