Mechanisms of nitrogen conservation at the leaf-level in annual and perennial desert forbs: Implications for perennial crops domestication
(Elsevier Gmbh, 2019-03)
Perennial plants show traits such as long-lived leaves and higher nutrient retention that provide a more efficient use of nutrients in low-resource environments when compared to annuals. These traits do not only generate ...
Germination of six native perennial grasses that can be used as potential soil cover crops in drip-irrigated vineyards in semiarid environs of Argentina
(Elsevier, 2014-09)
Native desert plants have structural adaptations that maximize photosynthesis rates and minimize water loss. They can be successfully utilized as soil cover crops in drip-irrigated vineyards where water availability is ...
The role of Sarcocornia perennis and tidal flooding on sediment biogeochemistry in a South American wetland
(Taylor & Francis, 2013-04-22)
The roles of Sarcocornia perennis and tidal flooding on sediment biogeochemistry were evaluated within a wetland in the Bahı´a Blanca estuary. pH and Eh were measured in sediments while particulate organic carbon (POC) and ...
Weed effects on the establishment and nutritive value of pastures with different annual/perennial ratio
(Wiley, 2020-12)
Livestock intensification is increasing weed invasion in pastures. We performed an experiment near Buenos Aires, Argentina, to evaluate the impact of weeds on temperate cultivated pastures. We sowed 1,700 viable seeds m–2 ...
Tradeoffs between productivity and nitrogen conservation in wild and domesticated plants of the perennial crop Physaria (Brassicaceae)
(Wiley Blackwell Publishing, Inc, 2018-09)
Domestication of desert-adapted perennials has been proposed as an alternative to increase cropping intensity in low input environments. However, selection for high yield in perennial crops provokes indirect changes in ...
Germination of six native perennial grasses that can be used as potential soil cover crops in drip-irrigated vineyards in semiarid environs of Argentina
(2015-02)
Native desert plants have structural adaptations that maximize photosynthesis rates and minimize water loss. They can be successfully utilized as soil cover crops in drip-irrigated vineyards where water availability is ...
Distribuição de Chironomidae (Diptera) em ecossistemas lênticos e lóticos no semiárido do Rio Grande do Norte
(Universidade Federal do Rio Grande do NorteBrasilUFRNEcologia, 2018-06-20)
The distribution of macrobenthic fauna is strongly influenced by changes in habitat, considered a great environmental bioindicator and is therefore among the most researched in aquatic ecosystems. Among the most studied ...
Performance evaluation of aerobic reactor and Sarcocornia perennis to reduce the COD and chloride of effluents from tanning sheepskins
(Inderscience Enterprises Ltd., 2017-10)
Tannery is an industry that generates wastewater characterised by high levels of organic matter, chrome, dissolved solids, sulphides and high salinity. The aim of this work was to evaluate at laboratory scale, the decrease ...
