Staying close: short local dispersal distances on a managed forest of two Patagonian Nothofagus species
(Oxford University Press, 2020-05)
Understanding the impact of management on the dispersal potential of forest tree species is pivotal in the context of global change, given the implications of gene flow on species evolution. We aimed to determine the effect ...
Borrelia genospecies in Ixodes sp. cf. Ixodes affinis (Acari: Ixodidae) from Argentina
(Elsevier, 2020-11)
The aim of this work was to evaluate the presence of Borrelia infection in Ixodes sp. cf. Ixodes affinis ticks from Argentina. Specimens of Ixodes sp. cf. I. affinis were collected on vegetation and birds in five locations ...
Frequency of bovine viral diarrhea virus (BVDV) in Argentinean bovine herds and comparison of diagnostic tests for BVDV detection in bovine serum samples: a preliminary study
(Elsevier, 2020-11)
Bovine viral diarrhea (BVD) is a major worldwide disease with negative economic impact on cattle production. Successful control programs of BVD require the identification and culling of persistently infected (PI) animals ...
Efficacy of immunization with a recombinant S. aureus vaccine formulated with liposomes and ODN-CpG against natural S. aureus intramammary infections in heifers and cows
(Elsevier, 2022-07)
The aims of the present study were to evaluate the ability of a subunit vaccine composed of recombinant molecules of α-toxin, β-toxin, FnBPA and ClfA, formulated with cationic liposomes and CpG-ODN, to confer protection ...
Detection by multiplex PCR of Mycoplasma species associated with dairy cattle in Argentina = Detección por PCR multiplex de especies de Mycoplasma asociadas a ganado lechero en Argentina
(Elsevier, 2021)
There is scarce information about the frequency and epidemiological and clinical features associated with the presence of Mycoplasma spp. in Argentine dairy herds. The objectives of this study were to develop a multiplex ...
First report of Mycoplasma leachii isolation associated with disease in dairy calves in Argentina = Primer aislamiento de Mycoplasma leachii asociado a enfermedad en terneros de tambo en Argentina
(2018)
There are few reports about the isolation of Mycoplasma species associated with cattle disease in Argentina. In this work we describe the detection of Mycoplasma leachii associated with disease in dairy calves in Santa Fe ...
Effect of row spacing on vegetative structure, fruit characteristics and oil productivity of N–S and E–W oriented olive hedgerows
(2015-09-22)
The effect of row spacing on fruit characteristics and production was studied in two super-high density olive hedgerow orchards planted at three row spacings (5.0, 4.0 and 2.5 m) with the same intra-row tree spacing, one ...
Equations of bark thickness and volume profiles at different heights with easy-measurement variables
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (España), 2012)
The objective of this work was to develop equations of thickness profile and bark volume at different heights with easy-measurement variables, taking as a study case Nothofagus pumilio forests, growing in different site ...
Light interception, yield, spring regrowth and quality of Chloris gayana under different defoliation regimes
(Taylor and Francis, 2022-02-22)
To study the effect of different defoliation regimes on light interception, forage yield, spring regrowth and quality of one of the most expanded species in this region, Chloris gayana, we evaluate combinations of two ...
Cover crop mixtures increase ecosystem multifunctionality in summer crop rotations with low N fertilization
(Springer Nature, 2022)
Cropping diversification with cover crop mixtures combined with low N fertilization represents an ecological alternative that may promote sustainability. Our objective was to evaluate changes on soil organic fractions and ...
