Relationships between stand parameters and understorey light in boreal aspen stands

, 2001
Data from six aspen stands in northeastern British Columbia ranging in age from 12 to 40 years were used to examine relationships between understorey light levels and stand attributes (basal area, stand density, and age).

Forest management drives evolution of understorey herbs

, 2023
Forest management has a strong impact on the forest structure and subsequently on the biotic and abiotic forest understorey environment. Forest understorey herbs can thus be expected to exhibit an evolutionary response to management-induced environmental

What drives animal responses to high severity fire? The role of functional traits

Biological Reviews, EarlyView.
ABSTRACT Fire regimes are changing worldwide, with increases in the frequency, extent, and severity of fires posing growing risks to biodiversity. Fire severity – the degree of habitat alteration following fire – strongly influences both immediate survival and long‐term recovery of fauna.

Use of Airborne Laser Scanning to assess effects of understorey vegetation structure on nest‐site selection and breeding performance in an Australian passerine bird

Remote Sensing in Ecology and Conservation, 2023
In wild bird populations, the structure of vegetation around nest‐sites can influence the risk of predation of dependent offspring, generating selection for nest‐sites with vegetation characteristics associated with lower predation rates.

Understorey removal effects on tree regeneration in temperate forests: a meta‐analysis [PDF]

, 2021
1. The unwanted development of dense understorey vegetation composed of resource‐acquisitive, tall plant species competing strongly with tree regeneration can pose formidable problems for managers attempting to regenerate temperate forests.

Hot and cold deserts as eco‐evolutionary arenas for understanding plant resistance to multiple abiotic stressors

Biological Reviews, EarlyView.
ABSTRACT During their long evolutionary history, land plants have evolved a range of adaptations to different abiotic stressors. These help explain present‐day diversity and distribution patterns, as well as the potential resilience of natural and agricultural systems to a changing climate. Most previous research has focused on adaptation to individual

Measuring understorey vegetation structure using a novel mixed‐reality device

, 2022
Most ecological studies of vegetation structure have relied on manual field measurements that are labour-intensive and time-consuming. Many current alternatives to classical measurements are expensive or difficult to transport to field settings.

Pteris madhusoodananii (Pteridaceae), a new fern species from India

Nordic Journal of Botany, EarlyView.
Pteris madhusoodananii sp. nov. (Pteridaceae), from the Kolli hills of Eastern Ghats, India, is described. The new taxon is morphologically distinct, characterized by a unique lamina texture and coloration, specific pinna‐pinnule architecture and distinct spore micromorphology.
