Fishery assessment models – the “backbone” of fisheries management – overstate sustainability of global fisheries

A study of 230 fisheries worldwide found significant biases in stock biomass estimates, particularly for overfished stocks, leading to underestimated declines and insufficient management. The findings suggest that 85% more stocks than currently recognized have likely collapsed below 10% of their historical biomass.

Environmental laws failing to slow deforestation

Research by University of Queensland reveals that Australian environmental laws are inadequate in stopping high rates of tree clearing for agriculture and development. The study found that 75% of cases in Queensland were exempt from assessment under the state's main vegetation management law, leading to severe deforestation rates.

Ben-Gurion University researchers offer proof of concept for unique aquaponics system

Researchers at Ben-Gurion University have created a proof-of-concept for a unique aquaponics system that grows fish and vegetables together, producing more produce while using less energy than traditional systems. The closed-loop system recycles fish waste through anaerobic digestion, reducing waste production and carbon emissions.

Forgotten predators: Ecological understanding is often marred by the exclusion of extirpated species

A recent study reveals that nearly 60% of ecological studies in national parks where gray wolves were extirpated overlooked the historical presence of these apex predators. This exclusion can lead to inaccurate assessments of ecosystem changes, which can have serious implications for conservation and wildlife management.

Biodiversity in the margins: Merging farmlands affects natural pest control

A new study found that removing hedgerows and field margins decreases the diversity and abundance of arthropods, which can lead to reduced natural pest control. The research suggests that using flowering plants in field margins and implementing agri-environmental measures can be effective ways to increase farmland biodiversity.

Improved refrigeration could save nearly half of the 1.3 billion tons of food wasted each year globally

A new University of Michigan study concludes that nearly half of the food produced globally each year goes to waste. Implementing fully refrigerated food supply chains worldwide could eliminate 620 million metric tons of global food loss and reduce climate-warming greenhouse gas emissions by 41%.

Regional differences in bird diversity in agroforestry systems

A study by the University of Göttingen investigated regional differences in bird diversity within cocoa agroforestry systems in Peru. The research team found that biodiversity decreases with increasing distance from natural forests, with greater richness of species found in humid subtropical forests than in dry tropical forests.

Severe hurricanes boost influx of juveniles and gene flow in a coral reef sponge

A study by Florida Atlantic University researchers found that severe hurricanes can increase the recovery of coral reef sponges by boosting the influx of juveniles and promoting gene flow. Genetic analyses revealed that populations of clonal marine species may benefit from increased frequency and magnitude of hurricanes to maintain gen...

Decommissioned offshore structures could offer only limited ecological benefits

A new study published in Nature Sustainability suggests that decommissioned offshore structures may only provide limited long-term ecological benefits. The research analyzed over 530 scientific studies on the effects of marine artificial structures and found no conclusive evidence to support their use as artificial reefs.

Scientists assemble a richer picture of the plight and resilience of the foothill yellow-legged frog

Researchers mapped disease dynamics in foothill yellow-legged frogs, tracing patterns of infection across a large geographic range. The study found that drought, rising temperatures, and agricultural land conversion drive Bd infection, with the pathogen affecting nearly entire region from southern coast to central Oregon.

Relocated songbirds can successfully learn the diversity of song they need to survive

A new study found that relocated songbird chicks can successfully learn the diversity of songs they need to communicate and survive. Despite an initial lack of song diversity, the population recovered as it increased in size, suggesting that translocating nestlings may not lead to long-term problems.

Tiny ant species disrupts lion’s hunting behavior

A study published in Science found that an invasive ant species is altering tree cover in an East African wildlife area, making it harder for lions to hunt their preferred prey, zebras. The ant's arrival has shifted predator-prey behavior, potentially jeopardizing lion populations already on the brink of endangerment.

Unpacking social equity from biodiversity data: an interdisciplinary policy perspective

Researchers found that biodiversity data is concentrated in wealthy countries, with implications for conservation projects. This context should be considered to prevent inequitable implementation, Chapman argues.
