“…Additionally, WV's increasingly temperate climate combined with decreasing temperature variance [9] may prolong episodes of excessive soil wetness and humid conditions that increases the vulnerability of terrestrial ecosystems to pathogens and fungal-like oomycetes such as Phytophtora and Pythium [48]. Similarly, increasing precipitation variance [9] indicates wet years are becoming more extreme, which may exacerbate vulnerabilities associated with pests and pathogens [49][50][51][52][53]. As a result, further investigation into changing climate variability may help to better explain observed changes in ecosystem biodiversity, carbon dynamics, and hydrology at a range of spatiotemporal scales [54].…”

“…Within five years of the discovery of BBD in Michigan, and with an expectation that it would kill at least half of the mature beech trees [92], McCullough and colleagues developed management strategies for beech forests at various stages (pre-infestation, advancing front, killing front and aftermath) [20]. Cale et al warn that "conditions within the current aftermath zone are a harbinger of what most beech stands may look like in the near future" in anticipation of additional and substantial Neonectria invasions [93] and in fact, bark phosphorous levels may be more relevant [94]. This is a more recent and disturbing finding when considering overall beech health.…”

“…Plus le rapport N/P du feuillage du hêtre est élevé, plus la probabilité d'infection par la MCH est grande. Ce résultat va dans le même sens que celui obtenu par l'équipe de Castello qui a trouvé qu'une concentration de l'écorce en P plus faible était associée à la présence de la MCH (Castello 2014;Cale et al 2015). Le rapport N/P est lié physiologiquement à l'équilibre entre la production des protéines, qui sont riches en N, et la production du catalyseur de la synthèse des protéines -l'acide ribonucléique ribosomique (ARNr) -qui est, pour sa part, riche en P (Loladze et Elser 2011).…”

“…Dans le nord-est des États-Unis, la pente du terrain et la composition du peuplement sont associées à la prévalence de la MCH (McCann et MacDonald 2013). D'autres travaux indiquent que la composition de l'écorce en éléments nutritifs (en particulier, l'azote [N] et le phosphore [P]), en acides aminés et en composés phénoliques est associée à la prévalence de la maladie (Cale et al 2015). Des chercheurs ont aussi trouvé que la résistance à la MCH avait une base génétique (Mason et al 2013) et que celle-ci se transmettait aux descendants (Koch et al 2010).…”
