Timber plantations near urbanized areas support the movement of small and medium-sized terrestrial mammals between patches of natural forest

Smithsonian Tropical Research Institute
Peer-Reviewed Publication

Researchers studied commercial timber plantations dominated by non-native trees like teak and acacia in Central Panama to assess their role as habitats and corridors for native wildlife. Using camera traps, they found 16 terrestrial mammal species, mostly small or medium-sized and nocturnal, using these plantations, but large mammals of conservation concern were not detected. The study highlights the potential of timber plantations to support biodiversity and connectivity in human-impacted landscapes but emphasizes the limitations of non-native monoculture plantations, advocating for plantations of diverse species to enhance wildlife conservation efforts.

Combination of drugs produces promising results in combating cancer and will be clinically trialed in Europe

Fundação de Amparo à Pesquisa do Estado de São Paulo
Peer-Reviewed Publication

Brazilian researchers innovated by stimulating tumor cells so much that they became stressed and could survive only by behaving like healthy cells. The results of the study were so promising that the researchers plan to hold clinical trials with patients, to be conducted in the Netherlands before the end of 2024.

Study proposes changes to simplify legislation on Atlantic Rainforest biome and enhance conservation

Fundação de Amparo à Pesquisa do Estado de São Paulo
Peer-Reviewed Publication

Lack of a method to classify forest succession stages in the applicable legislation allows for destruction of forest areas that provide important ecosystem services. The authors propose changes to make measurements more accurate and eliminate a step in permit applications that is ineffective and costly for landowners.
