Functional relationships between leaf hydraulics and leaf economics in response to nutrient addition in subtropical tree species
(Oxford Univ Press, 2013-11)
Leaves can be both a hydraulic bottleneck and a safety valve against hydraulic catastrophic dysfunctions, and thus changes in traits related to water movement in leaves and associated costs may be critical for the success ...
Functional relationships between hydraulic traits and the timing of diurnal depression of photosynthesis
(Wiley Blackwell Publishing, Inc, 2019-01-04)
The hydraulic coordination along the water transport pathway helps trees provide adequate water supply to the canopy, ensuring that water deficits are minimized and that stomata remain open for CO2 uptake. We evaluated the ...
Hydraulic architecture and photoinhibition influence spatial distribution of the arborescent palm Euterpe edulis in subtropical forests
(Oxford University Press, 2014-06)
Physiological characteristics of saplings can be considered one of the most basic constraints on species distribution. The shade-tolerant arborescent palm Euterpe edulis Mart. is endemic to the Atlantic Forest of Argentina, ...
Strong hydraulic segmentation and leaf senescence due to dehydration may trigger die-back in Nothofagus dombeyi under severe droughts: a comparison with the co-occurring Austrocedrus chilensis
(Springer Verlag Berlín, 2014-07-20)
Die-back was observed in South America temperate forests during one of the most severe droughts of the 20th century (1998–1999). During this drought Austrocedrus chilensis trees survived, whereas trees of the co-occurring ...
The stem xylem of Patagonian shrubs operates far from the point of catastrophic dysfunction and is additionally protected from drought- induced embolism by leaves and roots
(Wiley, 2013-03)
Hydraulic architecture was studied in shrub species differing in rooting depth in a cold desert in Southern Argentina. All species exhibited strong hydraulic segmentation between leaves, stems and roots with leaves being ...
Hydraulic differences along the water transport system of South American Nothofagus species: Do leaves protect the stem functionality?
(Oxford University Press, 2012-07)
Hydraulic traits were studied for six Nothofagus species from South America (Argentina and Chile), and for three of these species two populations were studied. The main goal was to determine if properties of the water ...
Compensatory responses in plant-herbivore interactions: Impacts of insects on leaf water relations
(Gauthier-villars/editions Elsevier, 2016-05)
Herbivore damage to leaves has been typically evaluated in terms of fractions of area removed; however morpho-physiological changes in the remaining tissues can occur in response to removal. We assessed the effects of ...
Homeostasis in leaf water potentials on leeward and windward sides of desert shrub crowns: water loss control vs. high hydraulic efficiency
(Springer, 2013-03)
Phenotypic plasticity in morphophysiological leaf traits in response to wind was studied in two dominant shrub species of the Patagonian steppe, used as model systems for understanding effects of high wind speed on leaf ...
Extending the generality of leaf economic design principles in the cycads, an ancient lineage
(Wiley Blackwell Publishing, Inc, 2015-04)
Summary: Cycads are the most ancient lineage of living seed plants, but the design of their leaves has received little study. We tested whether cycad leaves are governed by the same fundamental design principles previously ...
