The spatial variation in ant species composition and functional groups across the Subantarctic-Patagonian transition zone
- P. Fergnani, P. Sackmann, A. Ruggiero
- Biology
- Journal of Insect Conservation
- 1 April 2013
The role of ecotones in the maintenance of species diversity is rather controversial; they may represent either biodiversity hotspots with unique and rare forms, or be transitional areas that hold… Expand
Ants at the edge: a sharp forest-steppe boundary influences the taxonomic and functional organization of ant species assemblages along elevational gradients in northwestern Patagonia (Argentina)

- 1 February 2015
Biogeographic transitions may play a significant role in generating unique biodiversity patterns along different spatial dimensions of the geobiosphere. The extent, however, to which the presence of… Expand
Correction: Ecological Diversity in South American Mammals: Their Geographical Distribution Shows Variable Associations with Phylogenetic Diversity and Does Not Follow the Latitudinal Richness…
- P. Fergnani, A. Ruggiero
- Medicine
- PloS one
- 29 July 2015
The extent to which the latitudinal gradient in species richness may be paralleled by a similar gradient of increasing functional or phylogenetic diversity is a matter of controversy. We evaluated… Expand
The latitudinal diversity gradient in South American mammals revisited using a regional analysis approach: The importance of climate at extra-tropical latitudes and history towards the tropics
- P. Fergnani, A. Ruggiero
- Geography, Medicine
- PloS one
- 5 September 2017
The latitudinal diversity gradient has been considered a consequence of a shift in the impact of abiotic and biotic factors that limit species distributions from the poles to the equator, thus… Expand
Large-scale patterns in morphological diversity and species assemblages in Neotropical Triatominae (Heteroptera: Reduviidae)
- P. Fergnani, A. Ruggiero, S. Ceccarelli, F. Menu, J. Rabinovich
- Biology, Medicine
- Memorias do Instituto Oswaldo Cruz
- 18 July 2013
We analysed the spatial variation in morphological diversity (MDiv) and species richness (SR) for 91 species of Neotropical Triatominae to determine the ecological relationships between SR and MDiv… Expand
Richness‐environment relationships in epigaeic ants across the Subantarctic‐Patagonian transition zone
- P. Fergnani, P. Sackmann, A. Ruggiero
- Biology
- 1 November 2010
Abstract. 1. We analysed ant species richness‐environment relationships across the Subantartic‐Patagonian transition, in southern South America. We tested the predictions of the (i) thermal… Expand

Abstract The distribution and abundance variation of the terrestrial ants, Lasiophanes picinus and Lasiophanes valdiviensis Emery (Formicinae: Lasiini), which are endemic in Patagonia (Argentina and… Expand
