Larch dwarf mistletoe not found on alpine larch

, 1995
Reports of larch dwarf mistletoe parasitizing alpine larch are based on two collections of this host/parasite combination made by J.R. Weir in Montana during the early 1900s. Examination of host material from these collections indicates that the host is western larch, not alpine larch as previously reported.

Benefit or ecological trap? Monitoring the effects of small clear‐cuts on capercaillie Tetrao urogallus and its mammalian predators

Wildlife Biology, EarlyView.
The shift to ‘close to nature forestry' as the dominating forestry regime in western‐European forests has resulted in increasing timber volume and denser forests with negative effects on photophilic species. Hence, there is an increasing focus on active habitat management measures to support these species.

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.

Micro‐habitat selection by boreal woodland caribou improves access to food

Wildlife Biology, EarlyView.
Bio‐logging sensors attached to radiotelemetry receivers have great potential to transform our understanding of the ecological, physiological, and energetic constraints that shape patterns of wildlife movement under field conditions. We used video camera collars to assess microhabitat selectivity by woodland caribou Rangifer tarandus in boreal forests ...

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.

Changes of Potential Suitable Areas for Lynx Under Climate Change in Mohe Area, Daxing'anling Mountains, China 气候变化下中国大兴安岭漠河地区猞猁潜在适宜区的变化

Wildlife Letters, EarlyView.
Climate change drives shifts in suitable habitats for Eurasian lynx and its prey (hare, roe deer) in Mohe, Daxing'anling Mountains. Under RCP scenarios, moderate warming (RCP4.5) promotes substantial habitat expansion, while high‐emission conditions (RCP8.5) lead to strong expansion in the 2050s but slower gains and partial contraction by the 2070s ...

Alleviation of phosphorus rather than nitrogen limitation driven by permafrost and landscape effects on Dahurian larch forests

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Permafrost thaw is reshaping nutrient dynamics in boreal forests, but its impacts on tree nutrient limitation and functional strategies remain poorly understood. Clarifying these responses is crucial for predicting the response of boreal forests to climate change.

Targeted Trade Policy Instruments and Climate Change Mitigation: The Case of Environmental Provisions in Trade Agreements

Australian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT This article examines the effect of including environmental provisions (EPs) in preferential trade agreements (PTAs) on climate change mitigation and explores whether these effects vary based on the heterogeneity of the EPs. Our analysis combines country‐level data on climate change mitigation with details on 300 types of EPs in 775 trade ...

Why Settle for the Status Quo? A Critical Assessment of Pension Liability Measurement Under IFRS and US GAAP

Abacus, EarlyView.
Relevance and faithful representation are identified by standard‐setters as fundamental qualitative characteristics for useful accounting information. We critically assess whether current pension measurement guidance under International Financial Reporting Standards (IFRS) and US generally accepted accounting principles (GAAP) results in pension ...

The occurrence of Megastigmus pictus (Förster) (Hymenoptera: Torymidae) and Resseliella skuhravyorum Skrzypcz. (Diptera: Cecidomyiidae) in the Chełmowa Góra forest reserve of theŚwiętokrzyskiNational Park (Poland)

Journal of Forest Science, 2006
A study conducted in 1999-2000 in 6 compartments of the Chełmowa Góra forest reserve, situated in the ŚwiętokrzyskieMountains, was aimed at harmful insects infesting cones and seeds of Larix decidua Mill. subsp. polonica (Racib.) Domin.
