Assessing current curation, identification and digitisation practices in herbaria: Results from a global survey

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
The value of herbarium specimens depends largely on the accuracy and accessibility of the data captured, which is dependent on curation practices. Previous studies have shown high levels of misidentification in collections, which become more problematic with increased access.

Atmospheric mercury uptake to foliage using in situ and transplanted lichens at the New Almaden Mining District, California, United States

open access: yesFrontiers in Environmental Chemistry
Contaminated soils at former mercury (Hg) mines release Hg into the atmosphere that can be absorbed by the surrounding foliage and potentially contribute to inputs of Hg to downstream reservoirs and the food chain.

Lichens from Mount Kinabalu [PDF]

open access: yes, 1993
286 species of lichenized fungi on Mount Kinabalu are recorded by field survey and investigation of literature records and herbarium material. An annotated catalogue is presented, together with habitat notes, and a list of collectors. The summit area has

Incorporating soil biological and functional attributes to advance ecological restoration

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Earth is currently experiencing a mass extinction crisis, predominantly driven by anthropogenic activities, with land use change causing widespread loss and degradation of native ecosystems and indigenous species. There is an urgent need to halt this trend and restore degraded habitat to preserve biodiversity and protect threatened plants and animals ...

Conservation status of species used in the UK herbal medicine industry

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Given the ongoing biodiversity crisis, sustainable use and management of medicinal plants is critical. We assessed the conservation status, threats and conservation actions of 298 species sold by UK suppliers to medical herbalists. We found that most species used are unevaluated, representing a gap in conservation knowledge, and of those with ...

Toxicity of aqueous extracts of Ilex paraguariensis A.St.‐Hil. about Euphorbia heterophylla L.

open access: yesPest Management Science, EarlyView.
Aqueous extracts of Ilex paraguariensis A.St.‐Hil. strongly inhibit Euphorbia heterophylla L. germination and early seedling growth, but show mild phytotoxicity on mature plants, paradoxically promoting biomass via antioxidants. Abstract BACKGROUND The escalating challenge of herbicide‐resistant weeds, exemplified by Euphorbia heterophylla L.

Classification of tree species and standing dead trees in Boreal forests using UAV‐based RGB, multispectral, and LiDAR point clouds

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
We evaluated single‐ and multi‐sensor UAV approaches for classifying tree species and standing dead trees in boreal forests, focusing on key biodiversity indicators such as European aspen. Using spectral and structural features extracted from RGB, multispectral (MSP), and LiDAR point clouds for 1,205 field‐measured trees, we compared classification ...

A provisional survey of the interaction between net photosynthetic rate, respiratory rate, and thallus water content in some New Zealand cryptogams [PDF]

open access: yes, 1980
The effect of water content on photosynthetic and respiratory rates in eight lichen species and one bryophyte species were studied using an injection infrared gas analyser technique. All species snowed a strong relationship between net assimilation rate (

Successional changes in epiphytic rainforest lichens : implications for the management of rainforest communities

open access: yes, 2010
We explored lichen species richness and patterns of lichen succession on rough barked Nothofagus cunninghamii trees and on smooth barked Atherosperma moschatum trees in cool temperate rainforests in Victoria, Australia. Nothofagus cunninghamii trees from
