Unlike many other nations in the region, Colombia has not experienced the same political history of repressive dictatorships. As a result, the current literature on political graffiti does not cover the outlier case of Colombia. This research us...

Variability in mitochondrial DNA sequences was analyzed in the howler monkey, Alouatta caraya, in order to delineate evolutionary relationships among populations in the most southerly distributed New World monkey. Based on new and previously published sequence data, fourteen cytochrome b haplotypes were observed among 33 howlers sampled in Argentina, Paraguay and Brazil, and grouped in two main...

The Phanuromyia galeata species group is delineated and its species richness explored for the first time (Hymenoptera: Platygastridae, Telenominae). Fifteen species are described, all of which are new: Phanuromyia comata Nesheim & Masner, sp. n. (Brazil), P. constellata Nesheim, sp. n. (Paraguay), P. corys Nesheim & Masner, sp. n. (Brazil), P. cranos Nesheim & Masner, sp. n. (Bolivia, Costa Ric...

Wetlands are broadly defined as a variety of shallow water bodies and high ground water environments that are characterized by permanent or temporary inundation or, in other words, a terrestrial ecosystem which hydraulic condition is that of water saturated soils with plants and animals adapted to life in such an environment (Lewis, W.M., 1995). From a hydrological point of view, the Ibera wetl...

Stevia rebaudiana Bertoni is a shrub-like plant of the Asteraceae family, originating from Paraguay and Brazil, where it is used as a sweetener for therapeutic preparations, such as teas and other beverages, for hundreds of years. It is often called “sweet Paraguay honey” (Genus, 2003). The sweetener compound is obtained from the leaves of the plant by extraction (Prakash et al., 2008). The swe...

Botanists estimate that 80 to 90% of existing plant species have already been described and it is expected that most undescribed species are rare or narrow endemic ones. Here we map the geographical distribution of Gymnanthes boticario, a species described in 2010, and show that the species is not only widespread, but was well-collected in the Caatinga semiarid vegetation prior to its descripti...
