Water‐Regulated Carbon Cost–Benefit Drives Divergent Effective Rooting Depth Across the Greening Loess Plateau

open access: yesGeophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Large‐scale vegetation restoration is reshaping belowground systems globally, yet root dynamics remain poorly quantified, limiting predictions of ecosystem resilience to hydroclimatic variability. Rooting depth reflects a trade‐off between carbon benefits and respiratory costs, but assessment is hampered by soil‐moisture uncertainty and weak ...

Moderate Fire Temperatures Affect the Structure of Clayey Oxisol Aggregates

open access: yesLand Degradation &Development, Volume 37, Issue 8, Page 3169-3181, 15 May 2026.
ABSTRACT Wildfires have become increasingly frequent and intense worldwide, raising concerns about their impacts on soil systems. However, the thermal responses of clay‐rich Oxisols, dominated by Fe and Al oxides, remain poorly understood. In this study, samples from the 0 to 5 cm layer of six Oxisols were subjected to controlled heating at ...

Dry Bean Cocoa Production in Papua New Guinea: Do IPDM Inputs Pay Off?

open access: yesAsia &the Pacific Policy Studies, Volume 13, Issue 2, May 2026.
ABSTRACT Cocoa is Papua New Guineaʼs (PNG) third‐largest agricultural export, supporting about two million smallholder farmers. Despite integrated pest and disease management (IPDM) systems to improve yields, adoption remains low. We surveyed two cocoa‐growing households—one near Balima (Madang Province) and the other near Manetai (Bougainville)—and ...

Degree theory for 4‐dimensional asymptotically conical gradient expanding solitons

open access: yesCommunications on Pure and Applied Mathematics, Volume 79, Issue 5, Page 1151-1298, May 2026.
Abstract We develop a new degree theory for 4‐dimensional, asymptotically conical gradient expanding solitons. Our theory implies the existence of gradient expanding solitons that are asymptotic to any given cone over S3$S^3$ with non‐negative scalar curvature. We also obtain a similar existence result for cones whose link is diffeomorphic to S3/Γ$S^3/\

Population Genetics Reveals Insights Into Cryophytum Biogeography in South Africa

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
This study investigated the population genetic structure, biogeography and environmental drivers of divergence in Cryophytum crystallinum and C. guerichianum, two closely related Mesembryanthemoideae species, and evaluated a putative hybrid. Cryophytum crystallinum showed genetically similar populations at either end of its coastal range, with ...

Habitat fragmentation alters post‐dispersal more than pre‐dispersal seed predation through edge effects

open access: yesEcosphere, Volume 17, Issue 5, May 2026.
Abstract In addition to causing loss of biodiversity, habitat fragmentation can alter species interactions. Relative to well‐studied effects of fragmentation on mutualistic interactions like pollination, effects on antagonistic interactions remain poorly understood.
