Resilience of uneven-aged mixedwood stands altered by diameter-limit cutting and opportunities for their rehabilitation

The Forestry Chronicle
Repeated diameter-limit cutting in mixedwood forests often leads to altered stand composition, quality, and regeneration, hence decreasing productivity and value over time. We studied the evolution of stand characteristics after diameter-limit cutting on

Gamma Rays Signal the Vulnerability of Forest to Extreme Drought

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Extreme drought and heat are driving forest die‐off globally, yet regional‐scale mapping of subsurface water storage capacity, governing forest vulnerability, remains a major challenge. Here, we demonstrate that airborne gamma‐ray spectrometry (GRS) of potassium (40K) decay provides a powerful proxy for subsurface constraints on water ...

Response of ground-dwelling harvestman assemblages (Arachnida: Opiliones) to European beech forest canopy cover

European Journal of Entomology, 2017
We studied the effects of the overstory canopy cover on ground-dwelling harvestmen communities in European beech forests in the Western Carpathian Mts.

Optimising the Detection of Southern Toadlets (Pseudophryne semimarmorata): A Comparative Study of eDNA and Conventional Survey Methods

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 8, August 2026.
ABSTRACT Accurate and reliable monitoring of amphibians is essential for informing their conservation. Pseudophryne semimarmorata (southern toadlet) is a species of endangered brood frog with a largely terrestrial life history that has experienced widespread decline across southern Australia.

The primacy of species turnover over intraspecific variation in the environmental filtering of understory ferns

Frontiers in Plant Science
IntroductionQuantifying community-level trait shifts, driven by species turnover and intraspecific trait variation (ITV), is essential for understanding environmental filtering and elucidating community assembly and species coexistence.

Spatial and Temporal Variability of Throughfall among Oak and Co-occurring Non-oak Tree Species in an Upland Hardwood Forest

Geosciences, 2019
Canopy throughfall comprises the largest portion of net precipitation that is delivered to the forest floor. This water flux is highly variable across space and time and is influenced by species composition, canopy foliage, stand structure, and storm ...

Limited influence of nest site vegetation on female wild turkey survival during incubation

Ecosphere, Volume 17, Issue 8, August 2026.
Abstract Resource quality in heterogeneous environments directly underlies individual fitness. Gallinaceous birds, such as female eastern wild turkeys (Meleagris gallopavo silvestris), face significant reproductive challenges, particularly predation risk associated with ground nesting.

Characterization of Wildland Fuels Based on Topography and Forest Attributes in North-Central Appalachia

Fire
Forest ecosystem attributes and their spatial variation across the landscape have the potential to subsequently influence variations in fire behavior. Understanding this variation is critical to fire managers in their ability to predict fire behavior and

Decadal effects of fuel treatments and annual grass invasion on sagebrush ecosystem carbon stocks

Ecosphere, Volume 17, Issue 8, August 2026.
Abstract Fuel treatments are implemented across large spatial scales in sagebrush (Artemisia spp.) ecosystems of the US Intermountain West to limit wildfire risk and spread, but treatment effects on ecosystem carbon storage remain poorly understood. Fuel treatments can reduce aboveground carbon storage and may also influence belowground carbon storage ...

This is fine: Mule deer and elk do not substantially change their behavior in response to active wildfires

The Journal of Wildlife Management, Volume 90, Issue 6, August 2026.
During an outbreak of 7 wildfires in eastern Oregon, USA, we analyzed the home range and movement patterns of mule deer and elk before, during, and immediately after wildfires. Mule deer maintained high site fidelity during the wildfire but used their home range more uniformly and had higher daily displacement than deer unaffected by wildfire.
