(Asociación Herpetológica Argentina, 2012-10)
Especie abundante pero de restringida distribución, ocupa una pequeña franja del noroeste de Misiones, donde se halla su límite sur de distribución, aunque es probable que se esté expandiendo debido a su capacidad de ocupar ...
Canopy cover is a key factor to preserve the ecological functions of dung beetles in the southern Atlantic Forest
(Elsevier Science, 2020-10)
In general, livestock activities affect the diversity and ecological functions of dung beetles. However, some practices associated with tree retention could reduce this problem while maintaining productivity. The objective ...
Physical and chemical characteristics of pretreated slash pine sawdust influence its enzymatic hydrolysis
(Elsevier Science, 2019-04)
The aim of this work was to evaluate the effect of different pretreatments applied to industrial slash pine sawdust (Pinus elliottii) on its enzymatic hydrolysis. NREL laboratory analytical procedures for standard biomass ...
Do pine plantations provide mycorrhizal inocula for seedlings establishment in grasslands from Patagonia, Argentina?
(Springer, 2011-03)
We investigated if Pinus ponderosa plantations in Patagonia are able to produce viable mycorrhizal inocula towards adjacent grasslands, which only harbor endomycorrhizal vegetation. We hypothesized that these inocula have ...
Changes to anuran diversity following forest replacement by tree plantations in the southern Atlantic forest of Argentina
(Elsevier Science, 2018-09)
The replacement of native forests by high-density tree plantations affects the richness and composition of animal communities through the modification of the resource availability, hydrological regimes, nutrient cycles and ...

Se presenta una metodología para identificar y cuantificar las superficies forestadas a partir de datos satelitales. Las firmas espectrales, representan las características de reflectancia de diferentes formaciones arbóreas ...
Pine afforestation affects key primary producers in mountain grassland streams in Córdoba, Argentina
(Royal Society of New Zealand, 2017-10)
We evaluated changes in benthic algal community in grassland mountain streams converted to exotic pine afforestation. Three headwater streams draining grasslands and three draining plantations of Pinus elliottii were ...
Conifer plantations in grassland and subtropical forest: Does spider diversity respond different to edge effect?
(Springer Tokyo, 2018-09)
Two adjacent habitats separated by an abrupt transition often cause strong alterations in environmental conditions resulting in what is called the edge effect. The structural similarity between the adjacent habitats ...
