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 ...

First findings of an invasive tandem bark beetle – phytopathogenic fungus in the Middle Ural megalopolis [PDF]

Сибирский лесной журнал
The four-eyed fir bark beetle (Polygraphus proximus Blandford) and the fungus (Grosmannia aoshimae (Ohtaka, Masuya & Yamaoka) Masuya & Yamaoka) form an extremely aggressive invasive tandem affecting Siberian fir (Abies sibirica Ledeb.) throughout almost ...

Novel threats and response to Acadia National Park forests: Simulating the resist–accept–direct management framework

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.

Indirect effects of herbicide use on the Bombus community mediated through changes to shrub and forb communities

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

Development of a Dispersal Model for Balsam Woolly Adelgid, Adelges piceae Ratzeburg (Hemiptera: Adelgidae), to Facilitate Landscape-Level Management Planning

International Journal of Forestry Research, 2014
The balsam woolly adelgid (Adelges piceae Ratzeburg) attacks subalpine fir (Abies lasiocarpa (Hook.) Nutt.) in eastern Washington, Oregon, and northern Idaho.

Suboptimal host tree benefits the overwintering of a destructive forest insect pest

Basic and Applied Ecology, 2023
Winter represents a stressful period for many organisms, and terrestrial insects are particularly susceptible to adverse thermal conditions. However, exposure to thermal stress and its effects on insect survival and performance can be modulated by ...

Springtime resumption of photosynthesis in balsam fir (Abies balsamea) [PDF]

Tree Physiology, 2008
Photosynthesis in balsam fir (Abies balsamea (L.) Mill.) was measured in the field at two locations in New Brunswick, Canada from late winter to late spring in 2004 and 2005. No photosynthesis was detectable while the soil remained below 0 degrees C throughout the rooting zone. In both years, photosynthesis began once soil temperature rose to 0 degrees

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 ...

Meteorological versus spatial drivers of the spatial synchrony of forest insect pest outbreaks in North America

Oikos, Volume 2026, Issue 5, May 2026.
Spatial synchrony of population fluctuations has major consequences for the impacts of forest insect pest outbreaks at regional scales. We tested the predictions that the strength and drivers of this synchrony would differ among species according to their dispersal abilities and feeding guilds.

Using Landscape Genomics to Define Species Distributions, Delineate Seed Zones, and Predict Genomic Offset to Future Climate for the Interior Spruce Hybrid Complex (Picea glauca, Picea engelmannii, and Their Hybrids)

Global Change Biology, Volume 32, Issue 5, May 2026.
Using 41,253 SNPs from 252 interior spruce populations, we modeled gene‐climate relationships with Gradient Forest using the interior spruce hybrid complex. The model yielded important climate variables associated with local adaptation and can help visualize genomic variation with Principal Component Analysis.
