Última Invasion impact by Pteridium arachnoideum (Kaulf.) Maxon (Dennstaedtiaceae) on a neotropical savanna Acta Botanica Guerin,Natalia; Durigan,Giselda. Whether management intervention is required to control biological invasions depends primarily on demonstrating species losses resulting from such invasions. Brackens of the Pteridium genus are currently regarded as a problem species that act as important ecological filters in the assembly of invaded communities. We investigated the effects of Pteridium arachnoideum invasion on the diversity, structure, floristic composition, and functional traits of cerradão in Assis, São Paulo, Brazil. We compared an invaded site with an adjacent non-invaded site. Bracken constrained the establishment of tree species, resulting in a community structure remarkably distinct from the non-invaded area. The density and basal area of the arboreal community were higher in...

Ano: 2015 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0102-33062015000200213 Life history of Aneugmenus merida Smith (Hymenoptera: Tenthredinidae) in the Venezuelan Andes Neotropical Entomology Avila-Núñez,Jorge L.; Daniel Otero,Luis; Silmi,Sobeida; Calcagno-Pisarelli,Maria P.. Details of the life cycle of Aneugmenus merida Smith (Hymenoptera: Tenthredinidae) reared under laboratory conditions are reported. Females may produce parthenogenetic or non-parthenogenetic eggs. After eclosion, males of A. merida go through five larval instars, pre-pupa, pupa and imago. The complete life cycle lasts approximately 44 days. Larvae feed on bracken [Pteridium caudatum (L.) and Pteridium arachnoideum (Kaulf)] (Dennstaedtiaceae). We also report on morphological observations of the sinus sexualis in males by scanning electron micrographs and give details on mating behavior.
