(Universia, 2018-08)Soil macropores are dominant pathways of water flow and their impact on hydraulic properties is directly related to their geometrical and topological characteristics. A number of field and micromorphological analysis have ... -
Mapping a region within the 1RS.1BL translocation in common wheat affecting grain yield and canopy water status
(Springer, 2014-12)The translocation of the short arm of rye (Secale cereale L.) chromosome one (1RS) onto wheat (Triticum aestivum L.) chromosome 1B (1RS.1BL) is used in wheat breeding programs worldwide due to its positive effect on yield, ... -
Mapping extinction debt highlights conservation opportunities for birds and mammals in the south American Chaco
(2018-02)Habitat loss is the primary cause of local extinctions. Yet, there is considerable uncertainty regarding how fast species respond to habitat loss, and how time‐delayed responses vary in space. We focused on the Argentine ... -
Mapping QTL for resistance to new virulent races of wheat stripe rust from two Argentinean wheat cultivars
(Crop Science Society of America, 2018)During the last two decades, new virulent and aggressive races of Puccinia striiformis Westend. f. sp. tritici (Pst) have spread worldwide, causing devastating epidemics and prompting the search for new sources of resistance ... -

Mimosa diversiplla var. subglabriseta (MimosoIdeae, Leguminosae), a new record for the flora of Paraguay
(Sociedad Argentina de Botánica, 2012-12)The presence of Mimosa diversipila M. Micheli var. subglabriseta Barneby & Fortunato is now reported for first time in Paraguay. A revision of Barneby's initial description of the variety and photographs of one of the ... -
Mimosa serra (Caesalpinioideae, Fabaceae): conservation insights and its presence in Argentina
(Magnolia Press, 2022-11-30)In this work we detected the presence of Mimosa serra for the first time in Argentina and analyzed its distribution and status of conservation. In that country, it species is only known in one population in the Misiones ... -
Molecular evidence of hybrid zones of cedrela (Meliaceae) in the yungas of northwestern Argentina
(2016)In the Yungas of Northwestern Argentina, three endangered species of Cedrela (C. angustifolia, C. saltensis, and C. balansae) follow altitudinal gradients of distribution with contact zones between them. We sampled 210 ... -
Morphological and molecular identification of the invasive Xylosandrus crassiusculus (Coleoptera: Curculionidae: Scolytinae) and its South American range extending Into Argentina and Uruguay
(2017-05)The occurrence of the exotic “granulate ambrosia beetle” Xylosandrus crassiusculus (Motschulsky) in Argentina and Uruguay is reported for the first time, documenting expansion in South America. Morphological characters are ... -
Morphometric and Cytogenetic Studies in Mimosa diversipila (Mimosoideae, Leguminosae) and Their Taxonomic and Evolutionary Inferences
(American Society of Plant Taxonomists, 2014-07)Here we describe the morphological variability, chromosome number, and chromosome size in Mimosa diversipila. This species comprises two varieties, which are distinguished by the indumentum. However, this character is ... -
Multi-season regional analysis of multi-species occupancy : implications for bird conservation in agricultural lands in East-Central Argentina
(2015-07-18)Rapid expansion and intensification of agriculture create challenges for the conservation of biodiversity and associated ecosystem services. In Argentina, the total row crop planted area has increased in recent decades ... -
