How digitisation of herbaria reveals the botanical legacy of the First World War

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Digitisation of herbarium collections is bringing greater understanding to bear on the complexity of narratives relating to the First World War and its aftermath – scientific and societal. Plant collecting during the First World War was more widespread than previously understood, contributed to the psychological well‐being of those involved and ...

Herbarium digitisation sheds light on historical distribution and drivers of population extinction of a peat bog specialist

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Biodiversity loss threatens ecosystem services and human well‐being. Understanding the extent and causes of changes in biodiversity over time can help protect species and their habitats. Herbaria house carefully documented and curated specimens collected by generations of botanists.

Diet Composition Explains Interannual Fluctuations in Reproductive Performance in a Lowland Golden Eagle Population

open access: yesDiversity
Food supply stands out as one of the most critical drivers of population demographics by limiting reproductive rates. In this study, we assessed fluctuations in diet composition and monitored various reproductive parameters over a nine-year period in a ...

Open‐land‐derived agroforestry and effects of abandonment of management of the main crop on ecosystem services and woody plant diversity

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Tropical forests are rapidly declining. One promising strategy to reverse the loss of tropical forest is the establishment of agroforestry on open land. We combined interviews with biodiversity surveys to learn general lessons from success and nonsuccess stories of the establishment of open‐land‐derived coffee agroforests in one of the world's ...

Still on the same page: A gender comparison of the top 100 picture books from the UK and China published 2011–2020

open access: yesChildren &Society, EarlyView., 2023
Abstract As a primary source for the early ages, picture books guide preschool children's gender perception through stories and illustrations. However, previous studies have criticised an overall gender inequality in children's picture books. Compared to the increasing attention on gender diversity in the UK picture book industry, there has been little

Mitigating the mass dependence in the $\Delta\nu$ scaling relation of red-giant stars

open access: yes, 2017
The masses and radii of solar-like oscillators can be estimated through the asteroseismic scaling relations. These relations provide a direct link between observables, i.e. effective temperature and characteristics of the oscillation spectra, and stellar

Engineered Gravel Trench Hyporheic Exchange to Create Cold‐Water Thermal Refuges

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Warming rivers are driving a loss or fragmentation of cold‐water habitat and providing the impetus to develop proactive thermal management approaches to maintain suitable habitat in rivers. One innovative approach is through the creation of cold‐water thermal refuges during periods of thermal stress for aquatic species.

Atypical winter coat coloration of snowshoe hares near the southern extent of their range

open access: yesEcosphere
Many species have a variety of adaptations to winter weather, but these adaptations could become maladaptive if winter snowfall and temperatures are more variable.
