The role of morpho-physiological traits in frost tolerance of neotropical savanna trees
(2021-10-01)
Key Message: Frost-sensitive and frost-resistant Cerrado tree species differ in their morphological and physiological traits, which are linked with their resprout strategies and can affect their persistence under recurrent ...
Detecting Nothofagus pumilio Growth Reductions Induced by Past Spring Frosts at the Northern Patagonian Andes
(Frontiers Media S.A., 2019-10)
Extreme climatic events, such as late frosts in spring during leaf flush, have considerable impacts on the radial growth of temperate broadleaf trees. Albeit, all broadleaved species are potentially vulnerable, damage ...
Frost ring distribution in Araucaria araucana trees from the xeric forests of Patagonia, ArgentinaDistribución de anillos de heladas en árboles de Araucaria araucana en bosques xéricos de la Patagonia argentina
(Universidad Austral de Chile, 2012-11)
Frost rings are defined as anatomically abnormal and ecophysiologically pathological structures. The distribution of frost injuries in Early frost ring, Middle frost ring and Late frost ring in frost-ring chronologies were ...
Rare frost events reinforce tropical savanna–forest boundaries
(2018-01-01)
The ability of vegetation to ameliorate or exacerbate environmental extremes can generate feedbacks that mediate the distribution of biomes. It has been suggested that feedbacks between vegetation and frost damage may be ...
Frost damage on grain number in wheat at different spike developmental stages and its modeling
(Elsevier, 2019-02)
Frosts may damage wheat (Triticum aestivum L.) spikes and severely reduce their yield. The objective of this study was (i) to quantify the level of susceptibility to frost at different spike developmental stages, and (ii) ...
Frost record in tree rings linked to atmospheric circulation in northern Patagonia
(Elsevier Science, 2019-06)
Cold air incursions over subtropical South America are the precursor conditions for frost, a recognized extreme thermal weather event affecting plant growth damaging agricultural production over the whole Argentinian ...
Energetics of wave propagation leading to frost events in South America: extratropical latitudes
(Wiley VCH Verlag, 2017-08)
The dynamics of wave propagation and energy associated with frosts in extratropical versus tropical South American latitudes is studied. A double wave train propagates through the southern hemisphere following the polar ...
Rossby wave propagation tracks in southern hemisphere mean basic flows associated to generalized frosts over southern South America
(CENTRO CIENCIAS ATMOSFERA UNAM, 2010)
Based on previous observational studies on cold extreme events over southern South America, some recent studies suggest a possible relationship between Rossby wave propagation remotely triggered and the occurrence of frost. ...
Relationship between ENSO cycles and frost events within the Pampa humeda region
(John Wiley & Sons Ltd, 2000-11-15)
The objective of the present paper is to analyse the possible impact of ENSO events on the spatial and the temporal distribution of frost occurrences, within the central region of Argentina. Therefore, the minimum temperature ...
