Vegetation of montane bogs in east-flowing catchments of northern New England, New South Wales [PDF]

, 2013
The floristics of the montane bogs in east-flowing catchments of northern New England, north-eastern New South Wales (lat 28° 47’–31° 25’ S; long 151° 50’–152° 30’ E), are described from 62 full floristic survey sites (20 x 20 m in area).

Lower competition in grasslands and higher facilitation in forests as potential drivers of the higher species richness of calcareous than siliceous communities

Oikos, Volume 2025, Issue 12, December 2025.
We tested the hypothesis that, in calcareous and siliceous ecosystems from the wet temperate climate of southwest France, competition primarily explains differences in community composition and species richness in grasslands but that facilitation is more determinant in forests. In a first experiment, we transplanted, in dry and wet years, grass species

Holocene Land‐Use and Climate Forcing of Ombrotrophic Peatland Dynamics in Northwest Estonia

Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 12, December 2025.
Abstract We present a high‐resolution, multi‐proxy record from Mustjärve bog, northwest Estonia, covering the past ∼2,500 years. By integrating paleoecological, historical, and climate data, we evaluate how climate and land use shaped peatland hydrology, vegetation, and carbon dynamics.

Karaka (Corynocarpus laevigatus): native taonga (treasure) or environmental weed?

New Zealand Journal of Botany, Volume 63, Issue 5, Page 887-912, December 2025.
ABSTRACT Karaka (Corynocarpus laevigatus J.R. Forst. & G. Forst.) is an endemic New Zealand tree species that attracts polarising views and controversy. Prior to the arrival of humans in New Zealand, karaka was probably restricted to warmer areas of the northern North Island, but it now occurs throughout much of New Zealand, including on Rēkohu/Chatham

Global chloroplast phylogeny and biogeography of bracken (Pteridium; Dennstaedtiaceae) [PDF]

American Journal of Botany, 2009
Bracken ferns (genus Pteridium) represent an ancient species complex with a natural worldwide distribution. Pteridium has historically been treated as comprising a single species, but recent treatments have recognized several related species. Phenotypic plasticity, geographically structured morphological variation, and geographically biased sampling ...
