Ectomycorrhizal response to bark beetle attack: a comparison of dead and surviving trees
Bark beetle outbreaks have become increasingly prevalent and intense, causing widespread tree mortality and altering forest ecosystems globally. In this study, we investigate the dynamics between tree root systems of the Norway spruce and ectomycorrhizal

ABSTRACT The ecology of forests, their losses, and terrestrial wood decomposition dynamics have been intensively studied and reviewed. In the aquatic realm, reviews have concentrated on large wood (LW) in rivers and the transition from freshwater to marine environments in the Pacific Northwest of North America. However, a comprehensive global synthesis

Annotated Bibliography for Forest Managers on Fire-Bark Beetle Interactions
Forest managers in the western US are facing more fires and the most extensive bark beetle outbreaks recorded for the region. • Interactions of wildfire and bark beetle outbreaks and their reciprocal influences on fire behavior, bark beetle dynamics, and

Data for estimating spruce tree health using drone-based RGB and multispectral imagery
The dataset contains multispectral and RGB orthomosaics (.tif), and photogrammetric point clouds (.laz) of four study areas (about 25 ha each), where bark beetle-related decline of Norway spruce has been observed in Helsinki, Finland. The filenames refer

ABSTRACT Tool use research has long made the distinction between tool using that is considered learned and flexible, and that which appears to be instinctive and stereotyped. However, animals with an inherited tool use specialisation can exhibit flexibility, while tool use that is spontaneously innovated can be limited in its expression and facilitated

Early evolutionary history of the seed
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

Measures of niche overlap are important tools in various ecological and evolutionary studies. Here we create and apply a multispecies overlap metric to both simulated and empirical communities, illustrating how this methodology may capture interactions and structure of niche space in ways that traditional, pairwise metrics overlook.

Mountain-pine beetle outbreaks and shifting social preferences for ecosystem services
Conventional wisdom appears to implicate climate change as the root cause of the unprecedented mountain pine beetle (MPB) outbreak currently underway in the western United States.

The transferability of single or joint species distribution models ((j)SDMs) depends on their ability to predict beyond the observed environmental range and to remain consistent despite shifts in biotic interactions. Transfer accuracy may be improved by recent advances in the application of deep learning that provide greater flexibility and potentially
