The use of Leaf Surface Contact Cues During Oviposition Explains Field Preferences in the Willow Sawfly Nematus Oligospilus
(Nature Research, 2019-03-20)After an insect herbivore has reached its host plant, contact cues from the leaf surface often determine host acceptance. We studied contact cues during oviposition behavior of a willow pest, the sawfly Nematus oligospilus ... -
The use of nutritional blocks as a tool for grazing management in extensive sheep husbandry
(Asociación Argentina de Ecología, 2021-09-05)The improvement in grazing spatial distribution is an important goal for the efficient and sustainable management of rangelands. However, extensive livestock systems such as the Patagonian rangelands generally fails due ... -
The Use of Raw Poultry Waste as Soil Amendment Under Field Conditions Caused a Loss of Bacterial Genetic Diversity Together with an Increment of Eutrophic Risk and Phytotoxic Effects
(Springer, 2022-10-05)Poultry waste has been used as fertilizer to avoid soil degradation caused by the long-term application of chemical fertilizer. However, few studies have evaluated field conditions where livestock wastes have been used for ... -
The Use of Temperate Tannin Containing Forage Legumes to Improve Sustainability in Forage–Livestock Production
(MDPI, 2021-11-09)Greenhouse gas emissions from ruminant livestock production systems contribute significantly to the environmental footprint of agriculture. Emissions are lower for feedlot systems than for grass-based systems primarily ... -
The “polyploid effect” in the breeding of aromatic and medicinal species
(Elsevier, 2020-01)The secondary metabolism of plants delivers a wide range of chemical structures with application for a vast array of activities, thus offering opportunities for social and economic development. Polyploidy is the possession ... -
Thermal buffering capacity of the germination phenotype across the environmental envelope of the Cactaceae
(Wiley, 2017-06-28)Recruitment from seeds is among the most vulnerable stage for plants as global temperatures change. While germination is the means by which the vast majority of the world's flora regenerate naturally, a framework for ... -
Thermal history parameters drive changes in physiology and cold hardiness of young grapevine plants during winter
(Elsevier, 2018-11)Vitis vinifera is mainly cultivated in temperate areas, where seasons are well defined and winter conditions might be severe. To survive under these conditions during the dormant season, grapevines sense environmental ... -
Thermal regime and cultivar effects on squalene and sterol contents in olive fruits: Results from a field network in different Argentinian environments
(Elsevier, 2022-09-20)Some olive cultivars and production regions around the world, although they may provide good quality olive oils, may not comply with the current commercial regulations establishing acceptable levels of sterols in extra ... -
Thermal time and extreme weather events determine the emergence of Amaranthus palmeri
(Brazilian Weed Science Society, 2022-03-10)Background: Amaranthus palmeri has emerged as the most widespread weed of agricultural land in large parts of North and South America. Understanding its population dynamics and the influence of meteorological variables ... -
Think globally, measure locally: The MIREN standardized protocol for monitoring plant species distributions along elevation gradients
(Wiley, 2022-02)Climate change and other global change drivers threaten plant diversity in mountains worldwide. A widely documented response to such environmental modifications is for plant species to change their elevational ranges. Range ... -
Thinking in the sustainability of Nothofagus antarctica silvopastoral systems, how differ the responses of seedlings from different provenances to water shortage?
(2017-12)Nothofagus antarctica, is the most important species of the silvopastoral systems of southern Patagonia. However, there is limited information on the ecophysiological response mechanisms of seedlings for survival under ... -
Third Consecutive La Niña? What to Expect from Soybean Yields in the United States, Brazil and Argentina
(University of Illinois, 2022-05-23)International long-term forecast models hint at the possibility of a third consecutive La Niña event this year. It is not uncommon to see La Niña occurring over two successive seasons. This happened in both 2021-2022 and ... -
Three easy fixes for sire use can enhance genetic progress in community-based breeding programmes
(Wiley, 2021)We analysed options to optimize the use of sires in sheep and goat community-based breeding programmes (CBBP) for three scenarios occurring under field conditions: premature sale of selection candidates, fixed service ... -
Three new South American species of genus Aphis (Hemiptera: Aphididae) living on species of Euphorbia (Euphorbiaceae)
