Drivers of agricultural land - use change in the Argentine Pampas and Chaco regions
(2018-02)Agricultural expansion and intensification in South America's dry forests and grasslands increase agricultural production, but also result in major environmental trade-offs. The Pampas and Chaco regions of Argentina have ... -
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 ... -
Mimosa chacoënsis (Leguminosae), nueva cita para la flora Argentina
(2018-03)Mimosa chacoënsis, perteneciente a la sección Habbasia serie Rojasianae del género Mimosa, es citada por primera vez para la Argentina, en la provincia de Formosa. Esta especie, endémica de la ecorregión del Chaco Seco, ... -
Green spaces in a tertiary care children`s hospital benefits, taxonomic survey, and perspective
(2018-04)El contacto del ser humano con espacios verdes naturales tiene un efecto físico, mental y social beneficioso. Con el primer objetivo de conocer las especies vegetales de los jardines del Hospital de Pediatría Garrahan ... -
Changes in bird assemblages in a wetland ecosystem after 14 years of intensified cattle farming
(2018-05)Human activities have modified wetlands all over the word. Water control structures that are frequently implemented in these ecosystems to keep lands free of flooding can decrease or degrade habitat for biodiversity. The ... -
Genomic-based multiple-trait evaluation in Eucalyptus grandis using dominant DArT markers
(2018-06)We investigated the impact of combining the pedigree- and genomic-based relationship matrices in a multiple-trait individual-tree mixed model (a.k.a., multiple-trait combined approach) on the estimates of heritability and ... -
Venation Patterns in Mimosa subseries Dolentes and Brevipedes (Leguminosae) and their Taxonomical Inferences
(2018-06-21)Mimosa is a megadiverse genus of pantropical and subpantropical distribution. High morphological variability at infraspecific levels has often led to problems in the delimitation of taxa and the formation of taxonomic ... -
Trends in reference evapotranspiration and associated climate variables over the last 30 years (1984–2014) in the Pampa region of Argentina
(2018-07-21)Agricultural production is sensitive to weather and thus directly affected by climate change. In Argentina, the geographic region known as the “Pampa” is at the heart of agricultural production. In this context, the objective ... -
Macroporosity of a typic argiudoll with different cropping intensity under no-tillage
(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 ... -
Genetic variability of Araucaria angustifolia in the Argentinean Parana Forest and implications for management and conservation
(2018-08)The main forces shaping genetic variability of woody species in fragmented forest are the geographical distribution and demographic history of populations. We conducted molecular analyses to evaluate how these factors have ... -
Small mammal responses to farming practices in central Argentinian agroecosystems: the use of hierarchical occupancy models
(Ecological Society of Australia, 2018-08)Organic farming is more environmentally friendly than conventional agriculture, promoting greater levels of habitat heterogeneity. Field borders could be more suitable for biodiversity in agricultural anthromes. Small ... -
New data on the endangered Chacoan peccary (Catagonus wagneri) link the core distribution with its recently discovered southern population
(De Gruyter, 2018-09)The endangered Chacoan peccary (Catagonus wagneri Rusconi, 1930) has been recorded in western Paraguay, southeastern Bolivia and northern Argentina, reaching the north of Santiago del Estero province. Recently, however, ... -
Genetic diversity and differentiation among Prosopis alba (Leguminosae) populations from dry valleys of Bolivia with different levels of human disturbance and altitude
(Wiley, 2018-10-31)The fast expansion of human population around La Paz, Bolivia (3,200–4,100 m.a.s.l.) triggered new suburban settlements in nearby areas in valleys and mountain feet. The white mesquite, Prosopis alba Griseb. (Leguminosae), ... -
Genetic parameters for growth, stem straightness, and branch quality for Pinus elliottii var. elliottii × Pinus caribaea var. hondurensis F1 Hybrid in Argentina
(Oxford University Press, 2018-11)Genetic parameters for growth, stem straightness, and branch quality were estimated in five progeny trials of Pinus elliottii var. elliottii (PEE) × Pinus caribaea var. hondurensis (PCH) F1 hybrid measured at ages three, ... -
Quantitative genetics and genomics converge to accelerate forest tree breeding
(2018-11)Forest tree breeding has been successful at delivering genetically improved material for multiple traits based on recurrent cycles of selection, mating, and testing. However, long breeding cycles, late flowering, variable ... -
De novo transcriptome sequencing and SSR markers development for Cedrela balansae C.DC., a native tree species of northwest Argentina
(Plos One, 2018-12)The endangered Cedrela balansae C.DC. (Meliaceae) is a high-value timber species with great potential for forest plantations that inhabits the tropical forests in Northwestern Argentina.Research on this species is scarce ... -
Discontinuities in quinoa biodiversity in the dry Andes: An 18 - century perspective based on allelic genotyping
(Plos ONE, 2018-12-05)History and environment shape crop biodiversity, particularly in areas with vulnerable human communities and ecosystems. Tracing crop biodiversity over time helps understand how rural societies cope with anthropogenic or ... -
