A broad typology of dry rainforests on the western slopes of New South Wales [PDF]

open access: yes, 2013
Dry rainforests are those communities that have floristic and structural affinities to mesic rainforests and occur in parts of eastern and northern Australia where rainfall is comparatively low and often highly seasonal.

A phytosociological survey of the boreal forest (Vaccinio-Piceetea) in North America [PDF]

open access: yes, 1998
A survey of syntaxa of vegetation of North American boreal forests (class Vaccinio-Piceetea) is presented. This phytosociological survey, carried out combining the Braun-Blanquet method with numerical syntaxonomical analyses (cluster and correspondence

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.

Floristic Study of Gageodo in Korea

open access: yesKorean Journal of Plant Resources, 2013
The flora of Is. Gageodo (N 34˚02´∼34˚05´, E 125˚05´∼125˚08) in Sinangun (Province Jeollanamdo) was surveyed from April 2010 to October 2011. The vascular plants from the results of 23 field surveys were revealed as 385 taxa; in total 98 families, 258 genera, 348 species, three subspecies, 31 varieties and four forms.

Living \u3cem\u3eMore Than\u3c/em\u3e Just Enough for the City: Persistence of High-Quality Vegetation in Natural Areas in an Urban Setting [PDF]

open access: yes, 2011
Urban environments pose special challenges to flora, including altered disturbance regimes, habitat fragmentation, and increased opportunity for invasion by non-native species. In addition, urban natural area represents most people’s contact with nature,

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 ...

Floristic variation in Sphagnum-dominated peatland communities of the Central Highlands, Victoria [PDF]

open access: yes, 2013
The floristic composition of Sphagnum-dominated peatlands in the Central Highlands region of Victoria was surveyed (37º 25´ S; 145º 50´ E). NMDS ordination and cluster analysis divided the peatland sites into two broad groups with altitude being the most

Early evolutionary history of the seed

open access: yesBiological Reviews, EarlyView.
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

Is 500m2 an effective plot size to sample floristic diversity for Queensland’s vegetation? [PDF]

open access: yes, 2013
Species area curves from 37 sites spanning the diversity of native vegetation in Queensland were examined. For the majority of sites investigated a 500 m2 plot captured about 80–90% of the vascular plant species present at the time of sampling. Floristic
