Changes in Species Richness and Composition of Tiger Moths (Lepidoptera: Erebidae: Arctiinae) among Three Neotropical Ecoregions.

Paraná, Yungas and Chaco Serrano ecoregions are among the most species-rich terrestrial habitats at higher latitude. However, the information for tiger moths, one of the most speciose groups of moths, is unknown in these ecoregions. In this study, we assess their species richness and composition in all three of these ecoregions.

[Germinating requirements of common vines from Chaco Serrano of Córdoba, Argentina].

Vines are conspicuous elements of floras in different ecosystems. Patterns of distribution and ecology of this group has been studied at regional scales, mainly in tropical areas, but less is known about factors affecting their distribution at smaller scales. In this study, the germinating requirements of common vines from two plant communities (open shrubland and woodland) in xerophytic mountain forests (Chaco serrano) were studied.
