Mode d'Introduction: Notes sur l'espèce pour cette localité:
A survey of 17 sites in the city of Uberlandia revealed that P.megacephala was by far the most abundant of the six exotic ant species identified. Notes sur la gestion de l'espèce dans cette localité:
Notes sur la localité:
"Uberlandia is within the Cerrado biome, which is characterized as a mosaic of plant physiognomies that range from open grassland to closed woodlands.
In addition, semideciduous and gallery forests occur in areas with more nutrient rich and/or wetter soils (Oliveira-Filho & Ratter, 2002). The Cerrado is recognized for its exceptional biodiversity of vascular plants, many of which are endemic
(reviewed in Castro et al., 1999; Oliveira-Filho & Ratter, 2002). It also is one of the most threatened ecosystems in South America, with over 40% of the biome converted to agriculture and the remainder highly fragmented (Arroyo et al., 1999; Klink and Machado, 2005)" (Pacheco &Vasconcelos, 2007). Impacts:
Compétition: The negative influence of exotic species on overall species richness in the green spaces of the city was likely due to P. megacephala outcompeting other species. Dernière mise à jour: 30/03/2010 12:55:49 p.m.
