Peterjamesia circumscripta (Leight.) D. Hawksw. (Roccellaceae: Ascomycota): First record to continental South America

First record of the Devonian lycophyte Leclercqia from South America

A single leafy stem from the Middle or lowermost Upper Devonian Campo Chico Formation, Sierra de Perija, western Venezuela, is the first record of the important Devonian herbaceous lycophyte Leclercqia from South America, usually considered as part of western Gondwana. The seemingly cosmopolitan distribution of this genus is discussed in relation to coeval assemblages and palaeocontinental reco...

First record of Trichosteresis Förster (Hymenoptera: Megaspilidae) from South America.

The family Megaspilidae worldwide comprises more than 450 species in 11 genera (Dessart 2006), but the fauna of the family in South America is poorly known. For example, Dendrocerus Ratzeburg has been the only named genus reported from either Argentina (Loiácono 1998; Martinez 2003) or Brazil (Loiácono & Margaría 2002). Trichosteresis Förster is considered a monotypic genus, recorded from Europ...

First record of the family Pseudochiridiidae (Arachnida, Pseudoscorpiones) from continental South America--a Pseudochiridium from a Brazilian cave.

Continental fire density patterns in South America

Aims Quantification of the effects and interactions of natural and anthropogenic factors, including climate, canopy structure, land use and management conditions, on vegetation burning. The study of these relationships is fundamental to predict regional fire patterns and develop sound management and regulation policies for biomass burning at national and global levels. Location Southern South A...
