Vegetation of Península Valdés: Priority sites for conservation
(Springer, 2017)
This chapter describes the main vegetation units of Península Valdés at scale 1:250,000 with emphasis on relevant physiognomic and floristic characteristics. Based on photogrammetry (aerial photograph pairs 1:60,000) and ...
Impact of ponderosa pine afforestations on soil organic matter (SOM) in semiarid steppes of western Patagonia, Argentina
(2017-10)
The western steppe of Patagonia, Argentina, is being afforested with conifers since long ago. However, the effects of this land-use change on some soil parameters are still unknown. We determined soil organic matter (SOM) ...

Phylogeography and palaeodistribution modelling of Nassauvia subgenus Strongyloma (Asteraceae): exploring phylogeographical scenarios in the Patagonian steppe
(Wiley, 2014-11)
The Patagonian steppe is an immense, cold, arid region, yet phylogeographically understudied. Nassauvia subgen. Strongyloma is a characteristic element of the steppe, exhibiting a continuum of morphological variation. This ...
Environmental factors related to the abundance and activity of ochlerotatus albifasciatus (Diptera: Culicidae) in an agricultural landscape of steppe arid climate
(Entomological Society of America, 2014-04)
Ochlerotatus albifasciatus (Macquart) is a flood water mosquito whose highest density has been found associated both with natural landscapes (prairies or grazing fields) in temperate and subtropical regions and with rainfall ...
Pinus contorta invasion into treeless steppe reduces species richness and alters species traits of the local community
(Springer, 2016)
Pinus contorta, one of the most invasive tree species in the world, has been proposed as a model species for improving our understanding of invasion ecology. In this study, we assessed the impact of P. contorta invasions ...
Modern pollen analysis in caves at the Patagonian steppe, Argentina
(Elsevier Science, 2011-08)
Cave fossil records from the Patagonian steppe (Argentina) have been largely used as a source of archaeological and palaeoenvironmental information. Major uncertainties exist, however, regarding the degree to which the ...
Long-term impact of domestic ungulates versus the local controls of the litter decomposition process in arid steppes
(Springer, 2021-08)
Aims: Soil processes in arid ecosystems are strongly controlled by resource scarcity. Grazing intensification can induce changes in ecosystem processes through multiple pathways, adding new constraints to those of local ...
A comparison of two types of sheep grazing management in a forest-grass steppe ecotone in southern Patagonia
(IRC, 2011-04-02)
A sustainable silvopastoral production in southern Patagonia ranch is the key for conservatioon of Nothofagus antarctica native forest under grazing management. The goal of this work was to compare the traditional grazing ...
Endemic tenebrionids (Coleoptera: Tenebrionidae) from the Patagonian steppe: a preliminary identification of areas of micro-endemism and richness hotspots
(Wiley, 2012-02)
Based on data from sixteen museum collections we listed the endemic tenebrionids that inhabit the Patagonian steppe. Then, according to the geographical location of the species, we identified areas of micro-endemism and ...
