Neoformation of soil aggregates after a volcano eruption in meadows of Northern Patagonia, Argentina
(2018-08-12)In June 2011, a natural event occurred in Patagonia, Argentina: The “Puyehue-Cordón Caulle” volcanic complex erupted, and particles from tephras (1-5cm) to very fine volcanic ash (44-500?m) where deposited in the direction ... -
Nest-departure behaviour of gynes and drones in the invasive yellowjacket Vespula germanica (Hymenoptera: Vespidae)
(Cambridge University Press, 2020-08)Inbreeding costs can be high in haplodiploid hymenopterans due to their particular mechanism of sex determination (i.e., single-locus complementary sex-determination system, sl-CSD), as it can lead to the production of ... -
Neumonía en un carnero Merino causada por Erysipelothrix rhusiopathiae

Neutral and adaptive variation in the most widely distributed native tree species in Patagonia: on the way to defining provenance regions for Nothofagus pumilio
(2018-09)In our ongoing project, we aim to define Provenance Regions (PR) for the species along its distribution range in Argentina, from 36º S to 55º S. We propose the combination of neutral genetic variation with quantitative ... -
New precipitation and temperature grids for northern Patagonia: Advances in relation to global climate grids
(Chinese Meteorological Society, 2016-02)Climate data of mean monthly temperature and total monthly precipitation compiled from different sources in northern Patagonia were interpolated to 20-km resolution grids over the period 1997–2010. This northern Patagonian ... -
New world goat populations are a genetically diverse reservoir for future use
(Springer Nature, 2019-02-06)Western hemisphere goats have European, African and Central Asian origins, and some local or rare breeds are reported to be adapted to their environments and economically important. By-in-large these genetic resources have ... -
Nitrate and nitrite absorption, recycling and retention in tissues of sheep
(Elsevier, 2021-07)Dietary nitrate is of increasing interest both for the pharmacological effects of its metabolites as well as its capacity to inhibit methanogenesis in the gut. A sequence of three experiments was conducted to investigate ... -
Nitrate and nitrite metabolism in ruminant livestock
(Edición del Autor, 2019)Global methane emissions from livestock have continue to rise in last decade due to the increasing ruminant population and demand for livestock products. Supplementing the diet of ruminants with nitrate (NO3) is an effective ... -
Nitrogen dynamics in field grown comice pears
(Oregon State University, 1990-05)The dynamics of N was studied in field grown Comice/Provence quince BA29 pears in Medford, Oregon. Total tree biomass, N content, and ¹⁵N evaluations suggest that young pears require little N (48 kg N ha⁻¹ yr⁻¹). About 45% ... -
