Radial growth of black cherry (Prunus serotina) at the northern limit of its native range
Ecosphere, Volume 17, Issue 5, May 2026.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 ...

Ecosphere, Volume 17, Issue 5, May 2026.Abstract How future pathogens will interact with climate change to affect forests is unknown. While specific predictions of complex interactions may be unreliable, exploring a gradient of disturbance severity and management can be informative. We simulated forests in Acadia National Park (ANP) in Maine, USA, under climate change.

Gremmeniella balsamea sp. nov. on balsam fir in Canada
, 2012 Gremmeniella balsamea sp. nov. is described from specimens collected on balsam fir (Abies balsamea) in eastern Canada. This is a fungal pathogen specific to balsam fir. Until now, it was considered to be G. abietina var.

Anti-Insect Secondary Metabolites from Fungal Endophytes of Conifer Trees
Natural Product Communications, 2009 Choristoneura fumiferana is the most economically-important insect pest in eastern North America. Historically, strategies to control epidemics have relied on chemical pesticides that are no longer approved for use.

Ecosphere, Volume 17, Issue 5, May 2026.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

Thyronectria balsamea on Abies fraseri in Pennsylvania and North Carolina
Plant Disease, 1997 In August 1996, several 4- to 6-m-tall Abies fraseri (Pursh) Poir. in Adams County, PA, were found bearing numerous dead branches and/or dead tops. The trees had been severely stressed by being ball-and-burlapped and replanted in 1993. Distinct cankers occurred between the living and dead portions of stems and branches.

Anthropogenic disturbance and trophic interactions mediate population viability of American martens
The Journal of Wildlife Management, Volume 90, Issue 4, May 2026.We present a simulation model of the probability of collapse to <10% of carrying capacity for American marten populations over a 50‐year time frame in relation to forest disturbance due to commercial harvesting and fur‐trapping levels. Probability of collapse differed between models that assumed no effect of logging (solid line), martens living in a ...

Canadian Journal of Remote Sensing, 2022 Spruce budworm (Choristoneura fumiferana; SBW) outbreaks in the northeastern USA and Canada are recurring phenomena leading to large-scale mortality of spruce (Picea sp.) and balsam fir (Abies balsamea (L.) Mill.) forests as susceptibility to SBW is ...
