Aggregate Matching Efficiency : A Stochastic Production Frontier Approach, France 1990-1994 [PDF]

We evaluate the determinants of aggregate matching efficiency changes through a stochastic Cobb-Douglas production frontier model. The efficiency coefficient is represented by a stochastic function of variables meant to capture workers and firms ...

Can Widely Used Methods Be Turned Into eDNA Samplers for Ground‐Dwelling Arthropods? Insights From Two Pilot Studies in West European Salt Marshes

Entomologia Experimentalis et Applicata, Volume 174, Issue 2, Page 164-177, February 2026.
This study evaluates bulk and eDNA metabarcoding via suction sampling and modified pitfall traps to monitor salt marsh arthropods. Suction sampling excelled in detecting overlooked taxa, whereas pitfalls were effective for Scarabaeinae. Results underscore the importance of adapting protocols to specific taxa and habitats and highlight the effects of ...

Forest Reburns Are Integral to Southern Europe's Disturbance Regimes

Global Ecology and Biogeography, Volume 35, Issue 2, February 2026.
ABSTRACT Aim Fire disturbances are integral to fire‐prone landscapes of southern Europe. While evidence of changing fire frequency has been documented, the dynamics of forest reburns—defined as previously burned areas that ignite again within intervals shorter than the historical range with which forests ecologically evolved—remain largely unexplored ...
