Analysis of propagule pressure and genetic diversity in the invasibility of a freshwater apex predator: the peacock bass (genus Cichla)
Provedor de dados: Neotropical Ichthyology
Autores: Carvalho,Daniel C.; Oliveira,Denise A. A.; Sampaio,Iracilda; Beheregaray,Luciano B.
An important step in invasive biology is to assess biological variables that could be used to predict invasion success. The study of genetics, evolution, and interactions of invasive and native species in invaded ranges provides a unique opportunity to study processes in population genetics and the capability of a species' range expansion. Here, we used information from microsatellite DNA markers to test if genetic variation relates to propagule pressure in the successful invasion of an apex predator (the Amazonian cichlid Cichla) into Southeastern Brazilian River systems. Invasive populations of Cichla have negatively impacted many freshwater communities in Southeastern Brazil since the 1960s. Reduction of genetic variation was observed in all invasive...

Management priorities for exotic plants in an urban Atlantic Forest reserve
Provedor de dados: Acta Botanica Brasilica
Autores: Petri,Laís; Aragaki,Sonia; Gomes,Eduardo Pereira Cabral.
ABSTRACT Biological diversity is directly affected by alien species, even though the diagnosed impacts vary with scale. Early identification of the invasion of natural patches is essential for effective conservation actions. We aimed to determine the exotic plant species present inside Fontes do Ipiranga State Park (PEFI), an urban protected area located in the city of São Paulo, Brazil, and their relative proportions of occurrence in the native forest. Our goal was to use these data to assess their invasion status according to specific literature and to define management priorities for them. Therefore, we surveyed the presence of exotic plants within the canopy layer and understory of three native forest areas with different levels of disturbance. We...
