Rooting for hyphae: functional persistence of water transport from arbuscular mycorrhizal fungi to plants during soil dryingNARA Subscribed
Aims Arbuscular mycorrhizal fungi (AMF) are widely thought to support plant water uptake during drought, but whether their hyphae remain hydraulically functional once soil hydraulic conductivity collapses under severe drying, and how this depends on soil texture, remains unresolved. We tested whether AMF can maintain hydraulic functionality and transport water to plants under severe soil drying. Methods A simple conceptual fra...
When considering uncertainty, agroforestry can reduce trade-offs between economic and ecological benefitsNARA Subscribed
Persistent uncertainty about the economic implications of agroforestry presents a significant barrier to adoption. Despite this, most research to date ignores the impact of uncertainty on land allocation decisions, with studies commonly relying on simplistic scenarios involving a dichotomous choice between switching entirely to agroforestry or retaining the status quo system. For a more realistic decision problem, we explored...
After drought events, tree recovery depends on sufficient carbon (C) allocation to the sink organs. The present study aimed to elucidate dynamics of tree‐level C sink activity and allocation of recent photoassimilates (C new ) and stored C in c. 70‐year‐old Norway spruce ( Picea abies ) trees during a 4‐week period after drought release. We conducted a continuous, whole‐tree 13 C labeling in parallel with controlled watering a...
Expert range maps of global mammal distributions harmonised to three taxonomic authoritiesNARA Subscribed
Aim Comprehensive, global information on species' occurrences is an essential biodiversity variable and central to a range of applications in ecology, evolution, biogeography and conservation. Expert range maps often represent a species' only available distributional information and play an increasing role in conservation assessments and macroecology. We provide global range maps for the native ranges of all extant mammal spec...
Phylogeography of the ground squirrel subgenus Xerospermophilus and assembly of the Mojave Desert biotaNARA Subscribed
Aim The Mohave ground squirrel ( Xerospermophilus mohavensis ) is one of a few endemic species of the Mojave Desert of south‐western North America. We describe phylogeographic patterns within this species and its sister taxon ( Xerospermophilus tereticaudus ) and test hypotheses concerning their biogeographical history using genetic signatures of stable versus expanding populations. We compare these patterns with those of othe...
