Habitat fragmentation and amount drive within‐species variation in dispersal kernels and limit transferability across landscapes

Oikos, Volume 2026, Issue 8, August 2026.
Dispersal is a key ecological trait that ensures connectivity, gene flow, and range dynamics, yet empirical information about how dispersal distances vary within species remains scarce. Many studies, investigating for instance connectivity conservation, use typical species‐specific dispersal kernels without accounting for the fact that these kernels ...

Plasma proenkephalin‐a facilitates measurement of human kidney functional reserve: From healthy kidney donors to polymorbid patients

Physiological Reports, Volume 14, Issue 16, August 2026.
Enhanced measurement of Kidney Functional Reserve (KFR) by biomarkers: Protein ingestion stimulates intrarenal blood flow and increases glomerular filtration rate (GFR). KFR is [stimulated – baseline] GFR and can be assessed by biomarkers of filtration, including plasma proenkephalin‐A, plasma cystatin C, and creatinine clearance.
