Impacts of Pleistocene extinctions on the biomass and energy use of local mammal assemblages around the world

Ecography, EarlyView.
Many of the world's megafaunal species went extinct during the late Quaternary, leading to dramatic reductions in community and ecosystem functioning. While the nature and severity of the extinctions are well documented on global and continental scales, less is known about local‐scale impacts.

Extinct Pleistocene carnivores were diurnal and highly active

Ecography, EarlyView.
There is much contention over the causes and correlates of megafaunal extinctions at the end of the Pleistocene. A major role for human impact such as hunting has been discussed widely. If correct, the overkill hypothesis explains not only why large mammals in general were highly prone to extinction but suggests that extinction may have been selective ...

Water availability and evolutionary similarity shape the global distribution of ferns with chlorophyllous spores

Ecography, EarlyView.
About 14% of all fern species have chlorophyllous spores, which lack dormancy, have thin walls, and have a shorter viability (only a few days in some species). These spores should have limited dispersal distances and be more susceptible to harsher climatic conditions, raising questions about the evolutionary and ecological significance of this trait ...

Disentangling the interrelations of body mass, egg deposition site, climate and microhabitat use in frogs and salamanders

Ecography, EarlyView.
Amphibians exhibit a large diversity in reproductive and developmental strategies, which in turn are linked to their body size, life history and habitat. Here, we explore why terrestrial egg laying frogs are on average smaller than aquatic egg laying ones and whether this pattern also exists in salamanders.

Real‐Time Phosphate Monitoring via Plant‐Derived Graphene Ink FET Sensors Integrated with Deep Learning

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Accurate, real‐time nutrient monitoring is challenging in precision agriculture due to cost and technical limitations. Aligned with circular green economics, a deep learning‐integrated remote‐gate field‐effect transistor sensor with plant‐derived graphene electrodes offers a sustainable solution.

Resist!: Sustaining forest carbon sequestration and wood production after insect disturbance

Frontiers in Ecology and the Environment, EarlyView.
Disturbances from insect pests threaten ecologically and economically important goods and services supplied by forests, including wood production and carbon sequestration. We highlight the factors that influence these services’ resistance, a term quantifying the initial response to disturbance.
