Leaf paraheliotropism in Styrax camporum confers increased light use efficiency and advantageous photosynthetic responses rather than photoprotection
(Pergamon-Elsevier B.V. Ltd, 2011-04-01)
Styrax caporum is a native shrub from the Brazilian savanna. Most of its leaves are diaheliotropic, whereas some are paraheliotropic, mainly at noon. A previous study of this species revealed higher stomatal conductance ...

Global climatic drivers of leaf size
(American Association for the Advancement of Science, 2017-11)
Leaf size varies by over a 100,000-fold among species worldwide. Although 19th-century plant geographers noted that the wet tropics harbor plants with exceptionally large leaves,the latitudinal gradient of leaf size has ...
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 ...
A climatic and taxonomic comparison between leaf litter and standing vegetation from a florida swamp woodland
(2009)
One method to determine past climate has been the use of leaf morphological characteristics of fossil leaves quantifi ed using modern climate and canopy leaf characteristics. Fossil assemblages are composed of abscised ...
Responses of leaf δ13C and leaf traits to precipitation and temperature in arid ecosystem of northwestern ChinaRespuestas del δ13C foliar y características foliares a la precipitación y temperatura en un ecosistema árido del noroeste de China
(Fundación Rómulo Raggio, 2018-12)
El δ13C foliar es ampliamente usado para explicar estrategias relacionadas con la disponibilidad de recursos en diferentes ambientes. Sin embargo, la respuesta conjunta del δ13C foliar a la precipitación y temperatura así ...
The influence of temperature on oxygen consumption rates of workers of two leaf cutting ants, Atta laevigata (F. Smith, 1858) and Atta sexdens rubropilosa (Forel, 1908)
(Elsevier B.V., 1982-12-01)
1. 1. The oxygen consumption in workers of two simpatric leaf cutting ants, Atta laevigata and Atta sexdens rubropilosa was measured at different temperatures. 2. 2. In the temperature range between 5-35°C, with 5°C ...
Variation in leaf wettability traits along a tropical montane elevation gradient
(Wiley Blackwell Publishing, Inc, 2017-05)
Leaf wetting is often considered to have negative effects on plant function, such that wet environments may select for leaves with certain leaf surface, morphological, and architectural traits that reduce leaf wettability. ...
Trait-based scaling of temperature-dependent foliar respiration in a species-rich tropical forest canopy
The scarcity of empirical data on leaf respiration (R) and its temperature sensitivity (e.g. Q10, defined as the proportional increase in R per 10 °C warming) causes uncertainty in current estimates of net primary productivity ...
