One of the most important aspects for population ecology and evolution is to understand the connectivity between individuals and their groups. In this study, amplified fragment length polymorphism (AFLP) markers were employed aiming to examine genetic diversity, spatial genetic structure, and internal gene flow of nine populations of Schinus molle across(More)

Biodiversity is one of the most fundamental properties of Nature. It underpins the stability of ecosystems, provides vast bioresources for economic use, and has important cultural significance for many people. The Pampa biome, located in the southernmost state of Brazil, Rio Grande do Sul, illustrates the direct and indirect interdependence of humans and(More)
The Antarctic continent is the most untouched region of the world but is also among the most vulnerable to global environmental change. Alterations to the Antarctic environment can have cascading effects many of which are unpredictable. Our objective was to investigate the contribution of Brazilian scientists to Antarctic research and to characterize the(More)
The microbiota and the functional genes actively involved in the process of breakdown and utilization of pollen grains in beebread and bee guts are not yet understood. The aim of this work was to assess the diversity and community structure of bacteria and archaea in Africanized honeybee guts and beebread as well as to predict the genes involved in the(More)
Different environmental conditions are crucial to determine many attributes in plants by selective pressures. Plant traits and ecological interactions may present variation in outputs in these distinctive selection scenarios. In south Brazil, yerba mate (Ilex paraguariensis A. St.-Hil.) has been cultivated in monoculture and in consortium systems, differing(More)
Within and among population gene flow is a central aspect of the evolutionary history of ecosystems and essential for the potential for adaptive evolution of populations. We employed nuclear microsatellite markers to assess inter- and intra-population gene flow in five natural populations of Luehea divaricata growing in the Pampa biome, in southern Brazil.(More)
