“…Soil heterogeneity is another characteristic of the high-altitude vineyards in the Andes foothills of Mendoza. Due to their alluvial origins, these Entisols (unstructured soils) vary in terms of the volume of soil explorable by roots (Zárate and Mehl, 2019), called effective soil depth, which plays a key role in terroir expression. Soil characteristics have a major influence on plant performance and, therefore, on viticultural approaches to managing specific sites inside the vineyard (Reynolds et al, 2013;Reynolds and Rezaei, 2014;Brillante et al, 2016).…”

The high-altitude viticulture of Mendoza is being increasingly recognised among the top wine regions worldwide. High levels of solar ultraviolet-B (UV-B) radiation, alluvial heterogeneous soils and cool night temperatures are major influences on Vitis vinifera L. phenotypic characteristics, especially on Malbec, Argentina’s emblematic grapevine variety. In the present work, the effect of intra-vineyard contrasting soil depth on Malbec was evaluated in a high-altitude vineyard (1450 m a.s.l.), over two growing seasons for physiological traits and over three vintages for yield components and berry skin phenolic compounds. The experiment was carried out in two parcels of shallow (SS) and deep (DS) soils, with different physico-chemical characteristics, and submitted to equal irrigation and crop management. Results showed that root depth was not limited by any soil physical constraints and fine roots (< 1 mm) were patchily distributed in sites with higher contents of silt, clay and organic matter in SS. Higher root quantity in SS was related to lower vegetative and reproductive expressions, shorter ripening period and reduced berry size and fruit yield when compared to DS. When SS plants experienced mild water stress (ΨS, stem water potential, between -6 and -9 bar) increments of anthocyanins, total polyphenols and antioxidant capacity in berry skins were observed. However, when SS plants reached ΨS ≤ -10 bar, physiological harm occurred. The results presented contribute to understanding the effects of soil type on Malbec vines during different seasonal environmental conditions, especially in stressful situations, such as those expected by climate change scenarios.

The South American fauna has endured challenges such as illegal hunting, cattle expansion, climate change, and landscape fragmentation. Despite ongoing conservation efforts that aim to address these issues, genetic diversity remains overlooked. We genotyped 126 Lama guanicoe individuals from an area of 2 million km2 in Patagonia and Cuyo using the 60K SNPs Axiom-Camelids, and we assessed population viability through genetic diversity, inbreeding, and population size. We then explored population connectivities through network analyses, genetic differentiation, and Bayesian approaches. Our findings reveal six genetic clusters: Cuyo, Somuncura, North Patagonia, Central Patagonia, South Patagonia, and Tierra del Fuego Island (TDFI). Cuyo and TDFI guanacos differed from others due to isolation-by-distance and geographical barriers, respectively. Cuyo exhibited the highest degree of allele conservation, but TDFI faced heightened vulnerability due to isolation and increased homozygosity. Sharp bottlenecks in Cuyo and North Patagonia coincided with the expansion of sheep farming, while bottlenecks in the other populations occurred during the Little Ice Age. North Patagonia acted as a probable contact zone, facilitating mixing of the Cuyo, Somuncura, and Central Patagonia populations. The Central and South Patagonian populations presented the highest gene flow. Thus, genomic advances help to define distinct conservation units (genetic stocks) to guide management practices and decisions.
