Almost half of koala habitats will be under high bushfire threat by 2070      (via sciencedaily.com) 

The research team generated a series of fire susceptibility maps. These show the proportion of Australia experiencing 'high' or 'very high' fire susceptibility increasing from 14.9% now to 15.66% by 2070 -- while fire susceptibility of areas suitable for the plants that koalas depend on is tipped to jump from 39.56% to 44.61% by 2070.

Study shows replanting logged forests with diverse mixtures of seedlings accelerates restoration      (via sciencedaily.com) 

• Twenty-year experiment finds that active replanting beats natural recovery for restoring logged tropical forests. • The higher the diversity of replanted tree species, the more quickly canopy area and biomass recovered. • Results emphasize the importance of preserving biodiversity in pristine forests and restoring it in recovering logged forest.

Rivers are rapidly warming, losing oxygen; aquatic life at risk      (via sciencedaily.com)     Original source 

Rivers are warming and losing oxygen faster than oceans, according to a new article. The study shows that of nearly 800 rivers, warming occurred in 87% and oxygen loss occurred in 70%.

Protected nature reserves alone are insufficient for reversing biodiversity loss      (via sciencedaily.com)     Original source 

Protected nature areas are considered fundamental for maintaining biodiversity and countering its loss. But how effectively do established protected areas work and prevent negative trends? Research shows mixed effects of protected areas on various species.

Freshwater connectivity can transport environmental DNA through the landscape      (via sciencedaily.com) 

A new article uses environmental DNA (eDNA) metabarcoding to analyze fish and zooplankton communities. The study found that the movement of water between freshwater bodies, or freshwater connectivity, can transport eDNA. This highlights the potential of eDNA to provide a comprehensive view of freshwater biodiversity.

Nature's great survivors: Flowering plants survived the mass extinction that killed the dinosaurs      (via sciencedaily.com)     Original source 

A new study by researchers from the University of Bath (UK) and Universidad Nacional Autónoma de México (Mexico) shows that flowering plants escaped relatively unscathed from the mass extinction that killed the dinosaurs 66 million years ago. Whilst they suffered some species loss, the devastating event helped flowering plants become the dominant type of plant today.

Plant-based food alternatives could support a shift to global sustainability      (via sciencedaily.com) 

Replacing 50% of meat and milk products with plant-based alternatives by 2050 can reduce agriculture and land use related greenhouse gas (GHG) emissions by 31% and halt the degradation of forest and natural land, according to new research.

Lions on the brink -- New analysis reveals the differing threats to African lion populations      (via sciencedaily.com)     Original source 

New results reveal that many of Africa's remaining lions live within small, fragmented populations at risk of disappearing. The researchers developed a new framework which integrates ecological and socio-political risk factors to better understand the fragility of these populations.

New research highlights opportunities to protect carbon and communities from forest fires      (via sciencedaily.com)     Original source 

As the climate and wildfire crises have intensified, so too have concerns regarding the loss of carbon captured and stored in forests from decades to centuries of tree growth. A new study describes where to optimize ongoing wildfire mitigation efforts and reduce carbon loss due to wildfire, benefitting communities and climate at the same time. The study evaluated where living trees and the carbon they store are at risk of burning in the future. They then compared these areas to communities that are vulnerable to wildfire as identified in the Forest Service's Wildfire Crisis Strategy. Areas of overlap highlight 'opportunity hot spots' where action can reduce the risk from wildfire to both carbon and communities.
