A systematic review evaluating the performance of eDNA methods relative to conventional methods for biodiversity monitoring

open access: yesEcography, EarlyView.
The rapid adoption of environmental DNA (eDNA) methods has drastically changed biodiversity monitoring efforts. It is often claimed that eDNA methods are more sensitive and efficient than conventional biodiversity monitoring methods, but it is often unclear what metrics support this claim.

ENVIRONMENTAL COMPLIANCE IN U.S. AGRICULTURAL POLICY: PAST PERFORMANCE AND FUTURE POTENTIAL [PDF]

open access: yes
Since 1985, U.S. agricultural producers have been required to practice soil conservation on highly erodible cropland and conserve wetlands as a condition of farm program eligibility.

Co‐dominant species fail to compensate after 13‐year of dominant species removal in a Tibetan alpine grassland

open access: yesEcography, EarlyView.
To better understand the dynamics of community resilience, it is crucial to examine the role of dominant species in maintaining ecosystem functions. Dominant species, due to their high abundance, are considered to maintain productivity after species loss.

AIR POLLUTION AND FARM-LEVEL CROP YIELDS: AN EMPIRICAL ANALYSIS OF CORN AND SOYBEANS [PDF]

open access: yes
While many studies have estimated the impacts of air pollution on crop yields on experimental plots, few have estimated these impacts under actual farm production conditions.

Succession stages‐dependent shifts in grassland community stability from asynchrony to population stability mediated by nitrogen enrichment

open access: yesEcography, EarlyView.
Understanding the stability dynamics of naturally occurring grassland succession under nutrient enrichment is crucial for effective ecosystem management. We carried out an 11‐year field experiment to examine how grassland community stability responds to nitrogen (N) enrichment across the three successional stages (early‐, mid‐ and late‐successional ...

Soil organic matter and mineral content as crucial factors for the fate of tetracycline in soils

open access: yesEnvironmental Progress &Sustainable Energy, EarlyView.
Abstract Soil self‐cleaning ability and bioavailability of different pollutants are strongly dependent on the soil properties. It is not easy to determine effects of individual soil characteristics because they can impact together often in a synergic effect.

THE ECONOMICS OF GREEN PAYMENTS FOR REDUCING AGRICULTURAL NONPOINT SOURCE POLLUTION IN THE CORN BELT [PDF]

open access: yes
We develop a watershed-based model of green payments to examine how payments applied to different environmental performance measures compare on the basis of economic efficiency, equity, and environmental outcomes.

Policy Spandrels: How Design Decisions Can Open Up Spaces for Unintended Policy Change

open access: yesEuropean Policy Analysis, EarlyView.
ABSTRACT This article introduces the concept of policy spandrels to make sense of public policies producing second‐order effects that are unintentional from the perspective of policy design and yet are fraught with consequences. By analogy with architectural spandrels—leftover spaces that can be used for unforeseen purposes—policy change can be enabled
