Savanna soil carbon accrual occurs through particulate organic matter from grass rather than tree biomass, regardless of atmospheric CO2 levels

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Afforestation schemes in savannas are increasingly promoted as a carbon storage strategy despite threats to biodiversity. We also lack a clear understanding of how trees and grasses differentially contribute to the major carbon store in savannas, that is, soil organic ...

A catastrophic confluence: Concurrent subarachnoid haemorrhage and acute mesenteric ischaemia

open access: yesSurgical Practice, EarlyView.
Abstract Background Acute mesenteric ischaemia (AMI) and subarachnoid haemorrhage (SAH) are life‐threatening emergencies with diametrically opposed treatment requirements regarding anticoagulation. This report describes a rare, complex case where both conditions occurred simultaneously, creating a significant therapeutic dilemma. Case presentation A 64‐

Russian wheat aphid: a model for genomic plasticity and a challenge to breeders

open access: yesInsect Science, EarlyView.
Invasive foundress finds suitable habitat and reproduces through pathogenesis. Wingless females produce life offspring quickly, which leads to high population densities. High population densities result in competition, which may induce epigenetic changes and wing development for dispersal.

Robust estimation of key leaf traits from reflectance spectroscopy of herbarium specimens

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Community‐wide efforts to digitize herbarium specimens have facilitated novel uses of specimen data across scales. However, the need for destructive sampling has prevented large‐scale examination of foliar functional traits. We demonstrate that nondestructive reflectance spectra are an effective tool for estimating leaf traits from herbarium ...

Evidence for positive population‐level responses but not individual performance of sycamore aphids under elevated CO2

open access: yesAgricultural and Forest Entomology, EarlyView.
The abundance and density of three common sycamore aphids increased under elevated CO2, although this was only statistically significant for Drepanosiphum platanoidis. The number of nymphs produced by individual D. platanoidis alates isolated in clip cages was not significantly affected, suggesting that population level response was not driven by ...
