Evolution of seed dispersal in the Cerrado biome: ecological and phylogenetic considerations
Provedor de dados: Acta Botanica Brasilica
Autores: Kuhlmann,Marcelo; Ribeiro,José Felipe.
ABSTRACT The investigation of the phylogeny of a group of organisms has the potential to identify ecological and evolutionary processes that have been occurring within a community. Seed dispersal is a key process in the life cycle of vegetation and reflects different reproductive strategies of plants to a set of ecological and evolutionary factors. Knowing the dispersal syndromes and fruits types of a plant community may help elucidate plant-animal interactions and colonization strategies of plants. We investigated dispersal syndromes and fruit types in Cerrado formations as a parameter for understanding the evolution of angiosperm reproductive strategies in this mega-diverse tropical biome. To do this we identified and mapped the distribution of different...

Report of Sphenochernes camponoti (Beier, 1970) (Pseudoscorpiones, Chernetidae) in phoresy on Fanniidae (Diptera)

Phoresy is a common dispersal behavior among pseudoscorpions. Neotropical pseudoscorpions, mainly from the North and Northeast regions of Brazil, are known for their dispersal relationships with beetles and flies. Here, we report phoretic association among nymphs of Sphenochernes camponoti (Chernetidae) and Fannia flies (F. pusio, F. yenhedi, and F. canicularis) (Diptera, Fanniidae). Twelve flies, each carrying a young pseudoscorpion, were collected in Caatinga vegetation in Pernambuco State, Brazil. Sphenochernes camponoti is a myrmecophilous pseudoscorpion that lives in Camponotus and Acromyrmex colonies. Despite its association with ants, this pseudoscorpion uses other winged arthropods to disperse. This is the first report of phoresy by Sphenochernes...
