A broad survey of hydraulic and mechanical safety in the xylem of conifers.
(Journal of experimental botany, 2014-08)Drought-induced forest dieback has been widely reported over the last decades, and the evidence for a direct causal link between survival and hydraulic failure (xylem cavitation) is now well known. Because vulnerability ... -
A comparison of three methods to estimate evapotranspiration in two contrasting loblolly pine plantations: Age-related changes in water use and drought sensitivity of evapotranspiration components
(Forest Science, 2012-10-02)Increasing variability of rainfall patterns requires detailed understanding of the pathways of water loss from ecosystems to optimize carbon uptake and management choices. In the current study we characterized the usability ... -
Co-occurring woody species have diverse hydraulic strategies and mortality rates during an extreme drought.
(Plant Cell Environ, 2018-03)From 2011 to 2013, Texas experienced its worst drought in recorded history. This event provided a unique natural experiment to assess species-specific responses to extreme drought and mortality of four co-occurring woody ... -
Conversion of natural forests to managed forest plantations decreases tree resistance to prolonged droughts
(Forest Ecology and Management, 2015-01-01)© 2015 Published by Elsevier B.V.Throughout the southern US, past forest management practices have replaced large areas of native forests with loblolly pine plantations and have resulted in changes in forest response to ... -
Drought and thinning have limited impacts on evapotranspiration in a managed pine plantation on the southeastern United States coastal plain
(Agricultural and Forest Meteorology, 2018-11)© 2018 Managed and natural coastal plain forests in the humid southeastern United States exchange large amounts of water and energy with the atmosphere through the evapotranspiration (ET) process. ET plays an important role ... -
Drought will not leave your glass empty: Low risk of hydraulic failure revealed by long-term drought observations in world's top wine regions
(Science Advances, 2018-01-01)Copyright © 2018 The Authors, some rights reserved;. Grapevines are crops of global economic importance that will face increasing drought stress because many varieties are described as highly sensitive to hydraulic failure ... -
Ecophysiological impacts of Esca, a devastating grapevine trunk disease, on Vitis vinifera L.
(PloS one, 2019-01)Esca is a Grapevine Trunk Disease (GTD) caused by a broad range of taxonomically unrelated fungal pathogens. These attack grapevine wood tissues inducing necroses even in the conductive vascular tissues, thus affecting the ... -
Gold mining in the Peruvian Amazon: global prices, deforestation, and mercury imports.
(PLoS One, 2011-04-19)Many factors such as poverty, ineffective institutions and environmental regulations may prevent developing countries from managing how natural resources are extracted to meet a strong market demand. Extraction for some ... -
Growth and physiological responses of isohydric and anisohydric poplars to drought.
(J Exp Bot, 2015-07)Understanding how different plants prioritize carbon gain and drought vulnerability under a variable water supply is important for predicting which trees will maximize woody biomass production under different environmental ... -
Hydraulic redistribution of soil water by roots affects whole-stand evapotranspiration and net ecosystem carbon exchange.
(New Phytol, 2010-07)*Hydraulic redistribution (HR) of water via roots from moist to drier portions of the soil occurs in many ecosystems, potentially influencing both water use and carbon assimilation. *By measuring soil water content, sap ... -
Role of aquaporin activity in regulating deep and shallow root hydraulic conductance during extreme drought
(Trees, 2014-05-30)Key message Deep root hydraulic conductance is upregulated during severe drought and is associated with upregulation in aquaporin activity. In 2011, Texas experienced the worst single-year drought in its recorded history ... -
Variability of sun-induced chlorophyll fluorescence according to stand age-related processes in a managed loblolly pine forest
(Global Change Biology, 2018-07)© 2018 John Wiley & Sons Ltd Leaf fluorescence can be used to track plant development and stress, and is considered the most direct measurement of photosynthetic activity available from remote sensing techniques. Red and ...
