Beaver dams raised some stream biodiversity metrics—not every one
Sixteen Swiss paired stream comparisons separate aquatic gains from unchanged terrestrial indicators.

Acid-mine sludge may work in a soil blend—but not as soil itself
West Virginia reclamation microplots achieved vegetation cover goals under some waste blends.
Pollinator visits can also strengthen an invasive tree
Insect exclusion raised a question for blanket claims that more pollination always helps restoration.

A site-specific index detected substantial differences between intact, adjacent and converted landscapes.
A strong Vietnam streamflow score is not a forecast of next month
The best model uses weather information from the month whose flow it estimates.
High-seas genetic-data sharing has a treaty framework, not a finished system
An analysis of BBNJ provisions identifies capacity, governance and benefit-sharing questions.
Seagrass credits remain estimates—not verified atmospheric offsets
Mediterranean mooring measures were assessed against potential avoided carbon-stock losses.
Managed Yellow River pulses drive disproportionate modeled delta deposits
A few sediment-release days matter more than their share of the calendar.
Deer antibodies may locate tick exposure where surveys are thin
An Italian Alpine sentinel study measures past contact, not confirmed infections.
Bat immune profiles changed with season, but not all cell types did
A field-ready cell assay separates seasonal B-cell changes from nondetected shifts in other immune groups.
Brazil's São Francisco estuary contains more than visible plastic litter
Water, sediment and additive measurements reveal different contamination patterns along the same estuary.
Hatchery temperature tracked turtle nest failure; rainfall did not here
Four olive ridley nesting seasons reveal a locally actionable thermal signal and a useful null result.
A Namibia wildfire pushed savanna mammals beyond the burned boundary
Camera-trap occupancy fell for 31-species community; neighboring unburned areas were not a guaranteed refuge.
Floodplain reconnection usually helps biodiversity—but the test designs lag
A 100-study review across 22 countries finds promising responses and a shortage of strong counterfactuals.
Countries can map mangroves better than they can act on the maps
Thirty-five major mangrove countries show monitoring gains but weak correspondence with climate-policy ambition.
The Florida Keys lost sponges—and several functions with them
Hardbottom comparisons connect depleted sponge habitat with changed soundscape, bottom conditions and filtration.
Black ash wetlands lost carbon after both borer-like dieoff and intervention
A 12-year Minnesota experiment separates immediate carbon accounting from the long task of replacing an ash canopy.
Semi-arid restoration seed failed at salinity and temperature thresholds
Controlled tests of a native Iranian plant show why planting calendars alone cannot predict establishment.
Ethiopia's urban vultures reveal a citywide ecology of risk
Field counts around Jimma intersect with electrocution, poisoning and the scavenging services urban wildlife provide.
A burned landscape left some snail-shell bees a tiny refuge
Post-fire nests suggest microhabitat shelter can matter more than a broad burned/unburned classification.
Turning invasive plants into biochar can make another invasion worse
Microcosms tested biochar made from invasive biomass; some amendments favored growth of a different invader.
Four Korean marine heatwaves intensified under a warmer-climate model
Counterfactual ocean–atmosphere experiments distinguished added background warming from event-scale variability.
Brazilian watershed vulnerability changed unevenly across three basins
A regional preprint maps shifting landscape vulnerability, but the indicators are not direct measurements of river health.
