The extension of the taxon cycle model to island plants: insights from the Canarian vascular flora

open access: yesBiological Reviews, EarlyView.
ABSTRACT Taxon cycle models describe eco‐evolutionary patterns of lineage colonization, diversification, and decline across archipelagos, inferring an important role for competition amongst ecologically similar taxa in driving concurrent niche changes.

Plant community succession following ungulate exclusion in a temperate rainforest

open access: yesEcosphere, 2021
Ecosystem structure and processes of coastal temperate rainforests of the Pacific Northwest are thought to be strongly influenced by herbivory primarily of Roosevelt elk (Cervus elaphus roosevelti) and secondarily of Columbian black‐tailed deer ...

A Parasite of the Tree Fern (Cyathea)

open access: yesBotanical Gazette, 1919
July 14, 1915. On the older leaves the fungus is so abundant that the smallest frond segments, which measure about 3 X 7 mm., bear 25 or more of the black spots, and no segment is free of the fungus. On comparatively young fronds infections are less numerous, but even on such there are many fungous spots. A general idea of the appearance of the disease

Zero Deforestation Commitments and Industry 4.0 Enabling Technologies: An Analysis of Their Role in Mitigating Deforestation

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This study examines the role of corporate zero‐deforestation commitments (ZDCs) and Industry 4.0 (I4.0) enabling technologies in mitigating deforestation. Drawing on data from 110 companies included in the Forest 500 dataset, the research explores whether sustainability commitments and digital innovation influence firms' deforestation ...

Multivariate linear regression to predict association of non‐invasive arterial stiffness with cardiovascular events

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1141-1150, April 2025.
Abstract Background Arterial stiffness is a crucial factor in determining an increase in systolic blood pressure and pulse pressure and can also predict the development of cardiovascular disease (CVD). The purpose of this study was to examine the relationship between arterial stiffness and future CVD.

Quantifying the abundance of four large epiphytic fern species in remnant complex notophyll vine forest on the Atherton Tableland, north Queensland, Australia [PDF]

open access: yes, 2013
Epiphytes are generally considered rare in complex forests on the western edge of the Atherton Tablelands, north Queensland. This assertion is based on comparisons with wetter forests in the Wet Tropics bioregion, but is of limited use in restoration ...
