Seedling counts over 26 years revealed that wetter‐site temperate tree species struggle to recruit in warmer, drier years, whereas drier‐site species are more climate‐tolerant. Shadier forests buffered seedlings from heat and drought. Local soils and canopy cover strongly shaped outcomes, revealing considerable differences among species in climate ...

Predation pressure varies vertically, with highest arthropod predation in the understory and highest bird predation in the canopy. Light availability differs across vertical strata, but predation patterns are more strongly influenced by height and forest structure than by light gradients.

Branch mass allocation increases wind throw risk for Fagus grandifolia
AbstractWind is a major force of disturbance in forests throughout the world, causing trees to break or uproot and topple over, depending on tree morphology and growing conditions. Previous research has suggested that trees that are more massive or which have lower height–diameter ratios are less at risk to wind throw, but the influence of crown size ...

Formation of cis-Coniferin in Cell-Free Extracts of Fagus grandifolia Ehrh Bark [PDF]
American beech (Fagus grandifolia Ehrh) bark exclusively accumulates cis-monolignols and their glucosidic conjugates; no evidence for the accumulation of trans-monolignols has been found. The glucosyltransferase from this source exhibits a very unusual substrate specificity for cis, and not trans, monolignols.

Abstract Soil water deficits in temperate forests are projected to become more frequent, more severe, and longer in duration. This study aims to quantify the current (1981–2010) and projected (2041–2070) exposure of 17 tree communities to soil water deficit (severity and duration) in southwestern Quebec, Canada, using the Canadian Land Surface Scheme ...

Radial growth of black cherry (Prunus serotina) at the northern limit of its native range
Abstract Climate change is forcing us to reassess the foundational principles of forest management. Shifts in temperature, precipitation, and extreme weather events are altering both our understanding of forest ecosystems and how we steward them. Scientific research aimed at providing useful information can help forest managers make informed, evidence ...

Abstract Pesticides are used around the world to control and suppress undesirable species. In many cases the direct effects of pesticides are well understood and characterized, describing how environments are likely to be altered. However, these direct effects are likely to cause other species to respond to ecosystem alteration. For example, herbicides

Beech leaf disease (BLD) is a recently discovered disease that is causing severe damage to American beech (Fagus grandifolia) in northeastern North America. The recently described nematode Litylenchus crenatae subsp. mccannii was detected in BLD-affected
