• The spatial pattern of air seeding thresholds in mature sugar maple trees (2005, background): “Because cavitation in distal regions often leads to dieback of small branches (Sperry & Pockman 1993; Rood et al . 2000 ), the resulting reduction in total leaf area will lead to lower xylem tensions within the remaining portions of the plant (Tyree & Sperry 1988).”
• Traits to stay, traits to move: a review of functional traits to assess sensitivity and adaptive capacity of temperate and boreal trees to climate change (2016, unknown): “(Rood et al. 2000).”
• Functional and Ecological Xylem Anatomy (2015, background): “Rood et al. (2000) proposed that the great vulnerability to cavitation of riparian cottonwoods is a component of an unusual drought adaptation.”
• Species-specific water use by forest tree species: from the tree to the stand (2012, background): “Under extreme droughts, the hydraulic failure can make trees to sacrifice branches and show symptoms of crown die-back (Rood et al., 2000; Sperry et al., 1998).”
• Individual Tree and Stand Level Influences on the Growth, Vigor, and Decline of Red Oaks in the Ozarks (2008, background): “Despite the negative connotation of shoot dieback, in an evolutionary context, it has been argued to be adaptive for other woody species that incur severe droughts irregularly (Thomas and Hartmann 1996, Rood et al. 2000, Davis et al. 2002).”
• VESSEL REDUNDANCY: MODELING SAFETY IN NUMBERS (2007, background): “It has been argued that drought-induced embolism is one cause of branch die-back (Rood et al. 2000; Davis et al. 2002), that is, once sterns exceed the threshold of runaway embolism, they could quickly become 100 % air blocked.”
• Comprehending crystalline β-carotene accumulation by comparing engineered cell models and the natural carotenoid-rich system of citrus (2011, unknown): “Distal plant parts are arguably expendable; their sacrifice can help to maintain favourable plant water balance by reducing the total transpiring surface (Rood et al., 2000).”
• Xylem embolism refilling and resilience against drought-induced mortality in woody plants: processes and trade-offs (2018, background): “Alternatively, water-use can be decreased in some species by shedding leaves (Tyree et al. 1993) or branches (Rood et al. 2000).”
• LIFE HISTORY TYPE AND WATER STRESS TOLERANCE IN NINE CALIFORNIA CHAPARRAL SPECIES (RHAMNACEAE) (2007, methodology): “Thus, the water stress-coping strategy in R. californica at the adult stage is one where branches are periodically sacrificed to preserve whole-plant survival and ensure future repro- duction (Rood et al. 2000), a strategy incompatible with the NS life history type.”
• Water deficits and hydraulic limits to leaf water supply. (2002, background): “Transport failure has been associated with foliar desiccation in riparian cottonwoods subject to experimental soil drying or natural drought in floodplains subject to declining water tables (Tyree et al. 1994b; Sparks & Black 1999; Rood et al. 2000).”
• Will a 385 million year‐struggle for light become a struggle for water and for carbon? – How trees may cope with more frequent climate change‐type drought events (2011, background): “…refilling embolized vessels (Hacke & Sauter, 1996) and even if cavitation does persist, trees sacrifice more often small expandable distal parts (i.e. branches) rather than proximal parts (i.e. stem) because cavitation occurs more readily in the former than in the latter (e.g., Rood et al., 2000).”
