Innate Host Habitat Preference in the Parasitoid Diachasmimorpha longicaudata: Functional Significance and Modifications through Learning
(2016)
Parasitoids searching for polyphagous herbivores can find their hosts in a variety of habitats.
Under this scenario, chemical cues from the host habitat (not related to the host) represent
poor indicators of host location. ...
Undetermined cause of mortality in horses in Argentina
(2016)
The aim of this report is to describe the features and clinical findings in a series of equine mortalities occurred in a Thoroughbred and Quarter Mile horse breeding farm located in Canuelas, Buenos Aires Province, Argentina. ...
A contribution to understanding the origin of platy structure in silty soils under no tillage
(2016)
In silty soils under no tillage (NT), platy (P) soil structure is widespread and constrains water infiltration. Our objectives were (i) to evaluate how traffic and the presence of crop residues influence P structure ...
Land tenancy, soybean, actors and transformations in the pampas: A district balance

Effect of different cover crops on C and N cycling in sorghum NT systems
(2016)
In many no-till (NT) systems, residue input is low and fallow periods excessive, for which reasons soil degradation occurs. Cover crops could improve organic matter, biological activity, and soil structure. In order to ...
