Researchers have clarified the evolutionary history of a previously poorly known group of ferns from the tropical rainforests of America using DNA methods. The study discovered many new fern species, 18 of which have now been given official names and species descriptions.
Researchers from the University of Turku have described seven new fern species from the rainforests of tropical America. Many of the species were uncovered as the by-product of ecological research: the species diversity in tropical forests is still so poorly known that field trips and herbarium work keep discovering previously unknown species.
Why Latin America Matters is a collection of essays making the case for the importance of Latin America as a crucial region in global politics and development. Several researchers from the University of Turku have contributed to this book's theme on environment and sustainability.
An international team of researchers has compiled a large set of field data and reports that the number of hyperdominant tree species in Amazonian rain forests is three times greater than believed thus far. Hyperdominants are the most abundant species that together make up at least half of all the individuals that are studied. These results can be used for better planning of conservation and use of Amazonian forests.
Understanding the ecology and distributions of species in Amazonia is hampered by lack of information about environmental conditions, such as soils. Plant occurrence data are typically more abundant than soil samples in poorly known areas, and researchers from Finland and Brazil have now developed a method that uses both plant and soil data to produce a map of soil properties.
