Microtopography enhances intestinal drug absorption via Piezo1‐mediated tight junction modulation

open access: yesBMEMat, EarlyView.
Microtopography‐driven enhancement of oral peptide drug delivery by activating Piezo1 channels significantly improves paracellular permeability and bioavailability, offering a novel approach for optimizing macromolecule absorption in pharmaceutical formulations.

Mid‐Domain Effect and Wooded Habitat Shape Mediterranean Reptile Communities

open access: yesBiological Diversity, EarlyView.
Analyzing a large number of reptiles observed across protected areas in Central Italy, we tested whether the mid‐domain effect explains hump‐shaped richness–elevation patterns. Species richness was best predicted by the combined influence of geometric constraints and woodland cover, revealing two contrasting species clusters and offering a robust ...

Critical Analysis of Forest Degradation in the Southern Eastern Ghats of India: Comparison of Satellite Imagery and Soil Quality Index.

open access: yesPLoS ONE, 2016
India has one of the largest assemblages of tropical biodiversity, with its unique floristic composition of endemic species. However, current forest cover assessment is performed via satellite-based forest surveys, which have many limitations.

Five-Year Response of Spontaneous Vegetation to Removal of Invasive Amur Bush Honeysuckle Along an Urban Creek [PDF]

open access: yes, 2019
Non-native invasive species have major impacts on landscapes worldwide, but their effects in urban areas are not well documented. We quantified the response of naturally regenerating vegetation along an urban creek to removal of the invasive shrub ...

Habitat Characterization of Five Rare Insects in Michigan (Lepidoptera: Hesperiidae, Riodinidae, Satyridae; Homoptera: Cercopidae) [PDF]

open access: yes, 2018
Over 80 species of insects are listed as endangered, threatened, or special concern under Michigan\u27s endangered species act. For the majority of these species, detailed habitat information is scant or difficult to interpret. We describe the habitat of

Satellite hindcasts of foliar traits reveal a subtle but consistent relaxation of conservativeness in a biodiverse mountain grassland over the last four decades

open access: yesEcography, EarlyView.
Projected warming and drying raise concerns about the resilience of stress‐adapted ecosystems, including the Brazilian Campo Rupestre, an exceptionally biodiverse mountaintop grassland mosaic on ancient, nutrient‐poor substrates. Here, we combine field‐based trait data and long‐term remote sensing to assess the functional structure and temporal ...

The use of diatom records to establish reference conditions for UK lakes subject to eutrophication [PDF]

open access: yes, 2011
A knowledge of pre-disturbance conditions is important for setting realistic restoration targets for lakes. For European waters this is now a requirement of the European Council Water Framework Directive where ecological status must be assessed based on ...

Tracing the origins and evolution of nymphalid butterflies (Lepidoptera) in the Atlantic Forest

open access: yesEcography, EarlyView.
Understanding the relative roles of diversification and dispersal is key to explaining large‐scale biogeographical patterns. Although both processes are known to shape biodiversity, their relative contributions remain understudied for many organisms. Here, we examine how these processes have jointly contributed to the exceptional diversity and endemism
