On the Biodiversity Hotspot of Large Branchiopods (Crustacea, Branchiopoda) in the Central Paroo in Semi-Arid Australia

Zoodiversity, 2021
Biodiversity is central to the structure and functioning of communities including those of temporary water bodies.  Worldwide the large branchiopod component commonly consists of up to six species instantaneously co-occurring per site and twice that ...

Physicochemical and Microbial Diversity Analyses of Indian Hot Springs

Frontiers in Microbiology, 2021
In the present study, physicochemical and microbial diversity analyses of seven Indian hot springs were performed. The temperature at the sample sites ranged from 32 to 67°C, and pH remained neutral to slightly alkaline.

Do Random Forest-Driven Climate Envelope Models Require Variable Selection? A Case Study on Crustulina guttata (Theridiidae: Araneae)

Insects
Climate Envelope Models (CEMs) commonly employ 19 bioclimatic variables to predict species distributions, yet selecting which variables to include remains a critical challenge.

Effects of Helicobacter pylori Infection on the Oral Microbiota of Reflux Esophagitis Patients

Frontiers in Cellular and Infection Microbiology, 2021
The human oral microbiota plays a vital role in maintaining metabolic homeostasis. To explore the relationship between Helicobacter pylori (Hp) and reflux esophagitis, we collected 86 saliva samples from reflux esophagitis patients (RE group) and 106 ...

Varying responses of arthropod assemblages to clear‑cutting and aggregated retention harvestings

Journal of Ecology and Environment
Local environmental conditions shape forest biodiversity, while silvicultural practices like clear-cutting and retention harvesting can rapidly alter forest structure and microclimate, affecting ecosystem services.

Spiders indicate delivery of an agri-environment scheme at multiple diversity levels

Frontiers in Ecology and Evolution, 2022
Agri-environment schemes (AES) are expected to counteract the negative impacts of intensive agriculture on biodiversity. These schemes were specifically designed to target farmland biodiversity and included, for instance, ecological focus areas (EFAs ...

Avifauna diversity in the environmentally sensitive area: Alpha and Beta analyses in Kluang Forest Reserve, southern Peninsular Malaysia [PDF]

Biodiversity Data Journal
The Permanent Forest Reserve (PFR) is recognised as one of the Environmentally Sensitive Areas (ESAs) in Malaysia`s spatial planning. Incorporating biological factors alongside existing physical attributes is crucial to improve the classification of ESAs.
