Stingless-bee practices in South India span medicine, culture and management
A survey of 15 communities documented a knowledge system more diverse than conventional hive-production measures.
Regenerating eastern Amazon forest supplied flowers and fruit across the year
A post-bauxite-mine phenology survey documented plant resources without proving pollination or seed dispersal.
Sea-turtle monitoring documented beach-vehicle conflicts at Cape Hatteras
Field notes revealed repeated crossings of marked nests, while some nighttime effects were less detectable.
Cattle coats carried microalgae from Brazilian wetlands
A Neotropical field study found diverse algae on dairy cattle, revealing a usually invisible landscape connection.
Kubuqi greening measurements do not establish complete ecological recovery
An Inner Mongolian NDVI study recorded long-term vegetation gains while land-use shifts and forecasts remained uncertain.
Saline wetlands changed algae and rotifers differently
Across 61 Northeast China wetlands, local phytoplankton diversity declined with salinity-related conditions, unlike local rotifer diversity.
Wildfire effects on algal nutrients depended on stream valley position
Colorado nutrient-addition experiments detected seasonally changing limitation above and below river beads.
Food-web complexity explains part of biodiversity's functional value
Across 318 aquatic and terrestrial food webs, predator roles and trophic structure mediated modeled ecosystem energy flow.
Madeira marina monitoring shows a long accumulation of introduced species
Eleven years of surveys distinguished seasonal richness peaks from continued non-native species buildup.
Farm-economics constraints can change where ecological corridors fit
A Manitoba modeling framework connects habitat network design with producer-level profit and possible policy incentives.
Bison return did not consistently raise mixed-grass prairie plant diversity
Long-standing bison parks did not show a consistent richness advantage over nearby cattle-grazed grasslands.
Raising marsh elevation worked faster than rebuilding sparrow habitat
Across four Rhode Island marsh-restoration sites, sediment placement raised elevation while vegetation and wildlife recovered unevenly.
Budapest's ponds point to local ecology more than urban density
Mosquito abundance in 93 ponds was more strongly associated with fish presence than surrounding urbanization.
A deep-sea mollusc may have evolved a new chamber for bacterial power
Multilayered structures inside a cold-seep mollusc host sulfur-oxidizing microbial symbionts.
Reintroduced bilbies did not yet redraw the soil fungal map
After roughly three years, an Australian restoration site found no detectable soil fungal shift despite fungal DNA in bilby scats.
Wildlife-trade image recognition can triage, not convict
A prototype detector performed strongly on images of elephant, pangolin and tiger products, but enforcement effectiveness was not tested.
Forest soil-carbon comparison measured concentrations, not stored tonnes
An Anhui forest study found higher organic carbon concentration in mature native forest than in farmland or a pine monoculture.
Pacific reef imagery offers more than a one-number cover estimate
An updated NOAA catalog documents stratified structure-from-motion coral-reef transects across US Pacific island waters.
What counts as an Amazonian dominant tree depends on the metric
A 140-plot western Amazon analysis shows local abundance and spatial prevalence identify partly different dominant species.
Morocco's quinoa fertilizer gains met an emissions tradeoff
Field trials and modeled lifecycle impacts found diminishing grain-yield returns above a nitrogen threshold.
Park residents see tourism as an option, not always a skill they possess
Wildlife-related livelihood threats were associated with willingness to try tourism, but not with confidence in entering it.
Biochar's carbon signal depended on halophyte litter
A 370-day saline-soil microcosm performed differently when biochar was mixed with native plant litter rather than applied alone.
Good satellite water-quality accuracy can hide poor geographic transfer
A review of 127 inland-water studies reports promising machine-learning fits but serious geographic and variable gaps.
