Resistance of Pinus banksiana to the European race of Gremmeniella abietina [PDF]
, 2000 Au début des années 80, plus de 90 % de mortalité causée par Gremmeniella abietina, race européenne, a été relevée dans des plantations de pin rouge (Pinus resinosa) localisées à environ 200 km au nord-ouest de Montréal, Québec, Canada.

Self‐pruning in tree crowns is influenced by functional strategies and neighbourhood interactions
Functional Ecology, Volume 39, Issue 9, Page 2234-2250, September 2025.Read the free Plain Language Summary for this article on the Journal blog. Abstract As canopy closure imposes light limitation in forests, the dieback of trees' lower branches, known as self‐pruning, defines their live crown base and shapes the structure and function of entire stands.

Journal of Ecology, Volume 113, Issue 9, Page 2460-2475, September 2025.As temperate tree species require warmer temperatures than boreal species, some thermophilous species, such as white pine, increased in abundance at their northern edge during historically warmer periods. Our data reveal that not all temperate species behaved accordingly: maples were scarce during the warm mid‐Holocene, while their abundance increased ...
