Ticks (Acari: Ixodidae) parasitizing endemic and exotic wild mammals in the Esteros del Iberá wetlands, Argentina por Debarbora, Valeria Natalia, Nava, Santiago, Cirignoli, Sebastian, Guglielmone, Alberto, Poi, Alicia Susana G.

“…Also, a large number of the Esteros del Iberá collection records were for ticks from exotic (S.scrofa, A. axis, B. bubalis, L. europaeus) or reintroduced (M. tridactyla) mammals, suggesting that the introduction of these mammals may result in the amplification of tick populations in the study area, withpotential deleterious effects on the endemic fauna.…”

Exploring nitrogen limitation for historical and modern soybean genotypes por Ortez, O.A., Salvagiotti, Fernando, Enrico, Juan Martin, Prasad, P.V.V., Armstrong, P., Ciampitti, Ignacio A.

“…The United States (USA) and Argentina (ARG) account for over 50% of the global soybean [Glycine max (L.) Merr.] production. Soybean N demand is partially met (50–60%) by the biological nitrogen fixation (BNF) process; however, an unanswered scientific knowledge gap exists on the ability of the BNF process to fulfill soybean N demand at varying yield levels. …”

Surveillance and characterization of drug‑resistant mycobacterium tuberculosis isolated in a reference hospital from Argentina during 8 years’ period por Imperiale, Belen Rocio, Di Giulio, Angela Beatríz, Mancino, María Belén, Zumarraga, Martin Jose, Morcillo, Nora

“…DR geographical distribution revealed isolates carrying mutations in the inhA gene promoter region only constrained to three districts where it was also registered two same family relatives' cases with the infrequent rpoB S522 L/Q mutation. The fact that most DR/MDR-TB isolates were not grouped in genetic clusters suggested that these cases may mostly have occurred due to endogenous reactivation rather than recently transmission. …”

Water and solar radiation productivity of double-crops in a humid temperate area por Van Opstal, Natalia Veronica, Caviglia, Octavio, Melchiori, Ricardo Jose

“…Our aim was to evaluate water and solar radiation productivity, as a measure of the whole system efficiency, in sole-crops and double-crops in a humid temperate area of Argentina (31.5º S, 60.3º W, 110 m.a.s.l). An experiment including spring wheat, flax, rapeseed, peas and soybean as sole-crops and the sequential combination of winter crops with soybean as a second crop was carried out during the 2007/08 cropping season. …”
