A global meta‐analysis of non‐lethal mammal browsing control in forests

open access: yesBiological Reviews, EarlyView.
ABSTRACT Increasing resource demand, desire to sequester atmospheric carbon, and conservation goals are driving a need for forests to be managed more effectively in the face of numerous challenges. One such challenge is damage perpetrated by browsing mammals, which can cause substantial financial and ecological impacts.

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

open access: yesBiological 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

Diversity of Lecidea (Lecideaceae, Ascomycota) species revealed by molecular data and morphological characters [PDF]

open access: yes, 2010
The diversity of lichens, especially crustose species, in continental Antarctica is still poorly known. To overcome difficulties with the morphology based species delimitations in these groups, we employed molecular data (nuclear ITS and mitochondrial ...

Xylose Acetals ‐ a New Class of Sustainable Solvents and Their Application in Enzymatic Polycondensation

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
Novel organic solvents with an unmodified carbohydrate core were synthesised both from D‐xylose and directly from biomass and were successfully used as reaction media for lipase biocatalysts to synthesise aliphatic and aromatic polyesters. Abstract The use of organic solvents in academic research and industry applications is facing increasing ...

The projected risk of plant invasions on the peri‐Antarctic islands under climate change

open access: yesEcography, EarlyView.
The peri‐Antarctic islands have largely been shielded from alien plant species due to low human pressure, limited introduction pathways, and local harsh climates. However, climate change is expected to lower these barriers. We assess the vulnerability of 12 peri‐Antarctic islands to invasion by 2220 plant species invasive in at least one region of the ...

Responses of Antarctic seabird populations to past climate change

open access: yesEcography, EarlyView.
Higher‐order predators such as Antarctic seabirds serve as ecological indicators of environmental change and provide a crucial trophic link between marine and terrestrial ecosystems. Despite their prevalence and significance in the Antarctic ecosystem, there is a lack of understanding of the impacts of major regime shifts in paleoclimate on flighted ...
