Metagenomics Reveals Seasonality of Human Pathogenic Bacteria from Hand-Dug Well Water in the Cuvelai Etosha Basin of Namibia

open access: yesJournal of Pure and Applied Microbiology, 2019
Namibia is a large country with a population slightly above 2 million of which 73% live in rural areas. It is the driest country in sub-Saharan Africa with unpredictable rainfall patterns which occur between October and May. The Cuvelai Etosha Basin is

Transcriptional network analysis of PTEN‐protein‐deficient prostate tumors reveals robust stromal reprogramming and signs of senescent paracrine communication

open access: yesMolecular Oncology, EarlyView.
Combining PTEN protein assessment and transcriptomic profiling of prostate tumors, we uncovered a network enriched in senescence and extracellular matrix (ECM) programs associated with PTEN loss and conserved in a mouse model. We show that PTEN‐deficient cells trigger paracrine remodeling of the surrounding stroma and this information could help ...

Using Growth Forms to Predict Epiphytic Lichen Abundance in a Wide Variety of Forest Types

open access: yesDiversity, 2019
Epiphytic richness is continuously declining due to forest fragmentation, logging, burning, agriculture, and livestock. The rate of species loss caused by habitat degradation and loss is more pronounced in Central and South America.

Direct and indirect effects of environmental factors, spatial constraints, and functional traits on shaping the plant diversity of montane forests

open access: yesEcology and Evolution, 2020
Understanding the relative importance of the factors driving the patterns of biodiversity is a key research topic in community ecology and biogeography. However, the main drivers of plant species diversity in montane forests are still not clear.

Emerging patterns of species richness, diversity, population density, and distribution in the skates (Rajidae) of Alaska [PDF]

open access: yes, 2008
Six years of bottom-trawl survey data, including over 6000 trawls covering over 200 km2 of bottom area throughout Alaska’s subarctic marine waters, were analyzed for patterns in species richness, diversity, density, and distribution of skates. The Bering

Reserve Size And Fragmentation Alter Community Assembly, Diversity, And Dynamics [PDF]

open access: yes, 2013
Researchers have disputed whether a single large habitat reserve will support more species than many small reserves. However, relatively little is known from a theoretical perspective about how reserve size affects competitive communities structured by ...

Potential therapeutic targeting of BKCa channels in glioblastoma treatment

open access: yesMolecular Oncology, EarlyView.
This review summarizes current insights into the role of BKCa and mitoBKCa channels in glioblastoma biology, their potential classification as oncochannels, and the emerging pharmacological strategies targeting these channels, emphasizing the translational challenges in developing BKCa‐directed therapies for glioblastoma treatment.

Dynamics of Invertebrate Diversity in a Tropical Stream

open access: yesDiversity, 2014
Regional studies of biotic communities are important for characterising their normal spatial and temporal variation, but there are few such studies of tropical streams.

Planck/SDSS Cluster Mass and Gas Scaling Relations for a Volume-Complete redMaPPer Sample

open access: yes, 2017
Using Planck satellite data, we construct SZ gas pressure profiles for a large, volume-complete sample of optically selected clusters. We have defined a sample of over 8,000 redMaPPer clusters from the Sloan Digital Sky Survey (SDSS), within the volume ...

Similar biodiversity of ectomycorrhizal fungi in set-aside plantations and ancient old-growth broadleaved forests [PDF]

open access: yes, 2015
Setting aside overmature planted forests is currently seen as an option for preserving species associated with old-growth forests, such as those with dispersal limitation. Few data exist, however, on the utility of set-aside plantations for this purpose,
