Consortium of Brazilian researchers completes sequencing of native stingless bee's genome

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

Frieseomelitta varia is a docile species of economic interest as a pollinator. Its workers are sterile, and some of its genetic sequences are identical to those found in other eusocial bees, pointing to the conservation of ancestral traits.

Fossil trees on Peru's Central Andean Plateau tell a tale of dramatic environmental change

Smithsonian Tropical Research Institute
Peer-Reviewed Publication

The anatomy of plant fossils including an enormous tree that grew 10 million years ago in the now arid, high-elevation Central Andean Plateau calls current paleoclimate models into question, suggesting that the area was more humid than models predict.

Growing demand for zero-deforestation cacao might not help Colombian forests

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

Cacao in Colombia is not a major driver of deforestation - yet. But increased demand could imperil forests in the future. New research shows cacao stakeholders have to overcome barriers to reach markets that value zero-deforestation, complicating one of Colombia's post-conflict strategies.

Mother bats use baby talk to communicate with their pups

Smithsonian Tropical Research Institute
Peer-Reviewed Publication

When addressing infants, human adults tend to change the speed, pitch and "color" of their voice. This "baby talk" is known to facilitate language learning. According to new research at the Smithsonian Tropical Research Institute, it may not be exclusive of humans. Some bats have their own version of "baby talk" to communicate with their pups.
