Antarctic penguin deaths first linked to bird flu were largely avian cholera
Pathology and genetic analysis give a different diagnosis of a major wildlife mortality event.

Ecology, evidence and perspective.
Extreme rain left time-lagged patterns in China's Poyang Lake vegetation
Remote sensing suggests that wetland biodiversity responses differ by spatial scale and can follow precipitation with a delay.
On Spanish farms, wildlife cameras detected more taxa than water eDNA
A livestock–wildlife monitoring comparison finds complementarity, not an all-purpose replacement method.
Mozambique's miombo woodlands often burned again within a year
Landsat fire histories reveal how vegetation type structures the real disturbance regime in Niassa Special Reserve.
Harbour porpoises detected a net but still approached it closely
Drone and acoustic observations challenge the assumption that bycatch is simply a sensory detection failure.
Cerrado ecosystem risk cannot be read from a single vegetation map
A Brazilian ecosystem Red List identifies a large share of savanna, grassland, forest and wetland types as threatened.
Planting a forest and allowing one to grow created different kinds of value
A six-decade British chronosequence suggests biomass and biodiversity-oriented structure may favor different forest-creation approaches.
On atolls, seabirds, reefs and roots form one coastal defense system
Evidence from 28 atoll islands in the Indian and Pacific oceans links rat-free seabird colonies and native plants to the processes that build and hold islands.
Across hundreds of marine reserves, protected status did not guarantee less fishing
Vessel data from 861 marine protected areas expose the difference between drawing boundaries and reducing fishing pressure.
Protected wetlands held more birds, yet their populations were still falling
Thirty-four years of Finnish monitoring show why choosing valuable conservation sites and reversing decline are two different tests.
Frequent prescribed fire reduced shrub cover, but the wildlife-habitat tradeoff persisted
A long-term ponderosa-pine experiment found 5-year burns kept fuels and bitterbrush low, while 10- and 20-year regimes allowed different shrub and herb-layer outcomes.
US city density did not erase consumption's ecological footprint
An 83,603-census-tract analysis found slightly higher per-person ecological footprints in cities and near-linear scaling with urban population.
Wildlife cameras may be an underused understory phenology sensor
A methods commentary points to camera records as a complement to satellite and drone views of vegetation timing beneath forest canopies.
Moonlight's apparent effect on lion movement changed with the model definition
Six ways of coding the same Namibian GPS data generated inconsistent inferences; even better models explained little movement variability.
Arid streams in a rainfall gradient produced more secondary biomass than wetter ones
Nine rivers tracked for three years shifted from detritivore-heavy food webs in wetter settings toward vertebrate herbivory in drier settings.
Rare trees were missing from the youngest and oldest size classes in a Chinese watershed forest
Thirty-six plots in a major water-diversion intake area found that rare woody species occupied a narrow structural window.
Tropical forests' canopy-water buffer could weaken as atmospheric drying intensifies
Observation-based modeling found water held in canopies moderated past declines in photosynthetic water-use efficiency, but that benefit declined in projections.
Fire researchers linked airborne lasers, ground scans and field plots in one fuel dataset
Nine southeastern pine, five western pine and four western grassland sites now have aligned 3-D fuel data to test fire-model inputs.
One coastal resilience map was not enough for China’s local bays
A national land-and-water index and a nested Rongcheng diagnosis differed in what they could resolve; scores measured capacity, not observed recovery.
Great Lakes wetland plants yielded a more sensitive local disturbance index
A 41,314-plot dataset underpins a plant-based index that improved within-lake discrimination of water-quality and land-use stress.
Taipei's river chemistry improved, but bacteria did not follow the same trajectory
A 2010–2025 station record showed declines in several pollution metrics even as the coliform indicator rose between early and late survey windows.
In Himalayan coal-drainage streams, resistant diatoms tracked a mixture of chemical stresses
Three mine-affected streams differed from a comparison stream in acidity, metals and ions; algal assemblages reflected their combined chemistry.
Antarctic amphipods clustered where ocean currents met near Elephant Island
A newly published analysis of 2018 sampling found concentrated Themisto amphipods in warmer current-influenced waters, with many juveniles.
Exotic axis deer appeared more behaviorally flexible than native brocket deer
Camera traps in an Argentine protected area found more axis deer records and broader activity timing, but did not demonstrate competitive displacement.
