Spatial Distribution of Egg Clusters of the European Pine Sawfly \u3ci\u3eNeodiprion Sertifer\u3c/i\u3e (Geoff.) in Young Pine Plantations in Michigan [PDF]

, 2017
(excerpt) The European pine sawfly, Neodiprion sertifer (Geoffroy), is a perennial problem in young pine plantations in Eastern North America. Scotch pine, Pinus sylvestris L., and red pine, P. resinom Ait., are its principal hosts.

Assessing habitat suitability for black grouse broods at the bioregional scale

Wildlife Biology, EarlyView.
The black grouse Lyrurus tetrix, a galliform species emblematic of the European Alps, is currently threatened by habitat change, particularly given the closure of heathland linked to the rising tree line at higher altitudes. The presence of heathlands in good ecological condition is, however, imperative for the species' reproduction.

Allometric models to estimate tree height in northern Amazonian ecotone forests

Acta Amazonica, 2019
Allometric models defining the relationship between stem diameter and total tree height in the Amazon basin are important because they refine the estimates of tree carbon stocks and flow in the region.

Radial Growth of Qilian Juniper on the Northeast Tibetan Plateau and Potential Climate Associations [PDF]

, 2013
There is controversy regarding the limiting climatic factor for tree radial growth at the alpine treeline on the northeastern Tibetan Plateau. In this study, we collected 594 increment cores from 331 trees, grouped within four altitude belts spanning the

Quantifying microhabitat selection of snowshoe hares using forest metrics from UAS‐based LiDAR

Wildlife Biology, EarlyView.
Identifying the spatial and temporal scale at which animals select resources is critical for predicting how populations respond to changes in the environment. The spatial distribution of fine‐scale resources (e.g. patches of dense vegetation) are often linked with critical life‐history requirements such as denning and feeding sites.

Spatiotemporal Variation Characteristics of Ecosystem Service Losses in the Agro-Pastoral Ecotone of Northern China

International Journal of Environmental Research and Public Health, 2019
Being subject to climate change and human intervention, the land-use pattern in the agro-pastoral ecotone of Northern China has undergone complex changes over the past few decades, which may jeopardize the provision of ecosystem services.

Patterns and correlates of claims for brown bear damage on a continental scale [PDF]

, 2017
Wildlife damage to human property threatens human-wildlife coexistence. Conflicts arising from wildlife damage in intensively managed landscapes often undermine conservation efforts, making damage mitigation and compensation of special concern for ...

To converge or diverge? Phenological shifts driven by plant genome size and functional traits under nitrogen deposition and mowing

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Linkages between genome size (GS) and phenology underscore the diversification of functional traits, which are indicative of life‐history and resource acquisition strategies.

Reproductive limitation mediates the response of white spruce (Picea glauca) to climate warming across the forest–tundra ecotone

, 2019
Shifts in the extent of the boreal forest during past warm intervals and correlations between climate and the position of the forest–tundra ecotone suggest that recent temperature increases will fa...

Seasonal body mass dynamics mediate life‐history trade‐offs in a hibernating mammal

Journal of Animal Ecology, EarlyView.
We tested a suite of ecological hypotheses to explain variation in seasonal body mass dynamics of a fat‐storing mammalian hibernator. We further demonstrated that pre‐hibernation mass gain in ground squirrels mediates an annual allocation trade‐off between current and future reproduction as the squirrels forage and rear young under predation risk ...
