Novel method identifies areas most suitable for conservation of black lion tamarin

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

The researchers used modeling to show which areas are suitable in terms of forest cover and climate for occupation by the endangered species, which is endemic to the state of São Paulo. Their study is a contribution to translocation initiatives that move groups of these animals to areas from which the species has disappeared.

Scientists seek faster route to treat depression

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

The Brazilian research group used epigenetic modulators to try to 'erase' the damage done by stress to neuroplasticity. The study showed that acute intervention in epigenetic mechanisms produces antidepressant-like effects more rapidly than conventional drugs.

Study of dune dynamics will help scientists understand the topography of Mars

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

Researchers at the University of Campinas conducted more than 120 experiments with dunes of up to 10 cm that interact for a few minutes, obtaining a model valid for dunes on the surface of Mars that are many miles long and take more than a thousand years to interact

A no-meat diet everywhere will not solve the climate crisis

The Alliance of Bioversity International and the International Center for Tropical Agriculture
Peer-Reviewed Publication

Scientists argue Authors further argue that a singular focus on negative livestock-related environmental impacts ignores the critical but more positive role livestock play in ecosystem services, income and asset provision or insurance in low- and middle-income countries. It also overlooks more systemic questions about how animals are raised.

How much greenhouse gas emission comes from tropical deforestation and peatland loss?

The Alliance of Bioversity International and the International Center for Tropical Agriculture
Peer-Reviewed Publication

New research papers provide better data for tropical countries on how land conversion -- in this case, the removal of tropical forests and peatland for agriculture -- leads to increased greenhouse gas emissions.

Male bats with high testosterone levels have large forearm crusts when females are fertile

Smithsonian Tropical Research Institute
Peer-Reviewed Publication

Mammalian odors are frequently sexually dimorphic, with males often exhibiting a stronger, or otherwise distinct, odor relative to females, which can be especially useful for nocturnal species with reduced use of vision. Some male bats exhibit intense odors to attract females and reproduce, presumably as a consequence of a high concentration of testosterone.
