A roads meta-analysis found an average wildlife cost—and big uncertainty
A synthesis of 160 studies found a roughly 32% reduction on one effect scale, while other effect metrics were uncertain and site results varied greatly.

In western Rwanda, connected tree cover was not the same as connected biodiversity
Bird and woody-plant surveys at 91 sites favored connected traditional home gardens over connectivity dominated by exotic tree plantations.
After two decades of stream work, watershed-wide habitat signals were often missing
Thousands of habitat surveys across ten Washington watersheds found interannual changes often larger than long-term trends or expected restoration contrasts.
Marsh vegetation survived extreme waves by bending, not simply resisting
A full-scale Dutch wave-flume experiment found roughly 30% average aboveground biomass loss in severe simulated storms; flexible stems persisted most readily.
Forest-carbon transformation has a financing gap before the carbon advantage appears
Across five spruce-dominated Freiburg plots and 480 simulations, no management scenario won on every metric; transformation-oriented management paid an early biomass and revenue cost before potential additional carbon emerged.
Bangladesh’s urban tree-canopy benefits are distributed unevenly—and the numbers are model outputs, not field measurements
An all-city-corporation i-Tree analysis estimates large differences in air-pollution removal, carbon and stormwater services while highlighting implementation gaps in urban environmental policy.
Biodiversity science is starting to ask what ‘recovery-ready’ monitoring would look like
A new commentary argues that conservation science is much better at detecting decline than explaining and scaling recovery—and calls for outcome-based monitoring plus systematic learning from successes and failures.
Changing seed origin changed plant traits—but not the response to moisture extremes
A short-term nursery experiment with Chamaecrista fasciculata complicates the assumption that mixing or changing seed sources automatically changes performance under wet and dry extremes.
Light-pollution evidence is getting strong enough for a mitigation hierarchy—but regulation still lags
A new review prioritizes eliminating unnecessary light first, then spatial and temporal controls, with spectral tuning later in the mitigation hierarchy.
Plants and mycorrhizal fungi responded differently to rainfall change—but their spatial variability converged under drought
An Inner Mongolia precipitation experiment found plant and AMF diversity moving differently while reduced rainfall pushed both communities toward similar patterns of spatial compositional variability.
Belowground recovery tracked soil moisture more consistently than restoration label in one karst landscape
Across six vegetation-restoration systems, soil food-web maturity and microbial–nematode structure were more consistently associated with moisture and physical soil conditions than with the nominal restoration category alone.
Cropland expansion may cross nonlinear drought-risk thresholds in an agro-pastoral ecotone
A space-for-time analysis in northern China found drought and compound heat–drought risk increasing nonlinearly as cultivated land occupied more of the landscape.
Wetland carbon models scaled CO₂ better than methane
An ensemble model built from 24 southeastern U.S. wetland sites produced useful regional CO₂ estimates, but methane remained much harder to predict.
A high-Andean wetland metagenome found carbon-processing novelty, but little genomic support for methanogenesis
Genome-resolved sampling in Colombia’s páramo recovered many previously undescribed microbial lineages while methanogenesis markers remained scarce in the assembled genomes.
Citizen science did not add species richness—but it transformed the map of non-native molluscs
In Brazil’s Caatinga, museum and collection records captured more species overall, while citizen-science records disproportionately documented non-native molluscs and expanded spatial coverage.
Reintroduced hyenas used dense cover, water—and roads only when human pressure was low
Tracking five spotted hyenas in a fenced South African reserve links space use to vegetation, permanent water, prey and the timing of human disturbance.
After wildfire, different carbon tracers leave watersheds on different clocks
Five California coastal watersheds showed an early pulse of fire-derived levoglucosan while black-carbon export was more discharge-driven and became more prominent later.
Diversity in dispersal strategies can buffer competitive-exclusion risk
A new framework combines abundance, dispersal diversity and competition to estimate local-extinction vulnerability; forest data suggest heterogeneous dispersal strategies can reduce exclusion risk.
Urban reef fish looked well fed and stressed at the same time
Transcriptomes from blue damselfish across 18 Okinawa coastal sites linked urbanized habitats with energy-rich nutritional signatures and elevated immune and inflammatory responses.
Total soil carbon stayed similar while shrub expansion shifted it toward a less stable form
On the Tibetan Plateau, slower shrub-litter decomposition increased particulate organic carbon but reduced mineral-associated organic carbon—a compositional change that a total-SOC metric would miss.
Gambia’s oyster fishery is an ecological system, a women’s livelihood and a governance system at the same time
Interviews with 60 female oyster harvesters show how tidal knowledge, family-transmitted practice, commercialization and formal closures are interacting inside two mangrove–oyster social-ecological systems.
Invasive-plant control can turn a salt marsh from carbon sink to carbon source—at least during recovery
An eastern China study found both herbicide and cutting-plus-flooding control of invasive Spartina reversed net carbon uptake, while the two methods changed methane, soil carbon and carbon stability in different ways.
Open glades may use herbivores to hold back woody regrowth
Paired exclosures suggest a savanna-clearing response depends on woody species identity and browsers' preferences.
A Colombian watershed model maps flood and landslide risk with green infrastructure options
A planning framework links hazard records with places for forest, floodplain, pond and wetland investments.
