Insect Science, EarlyView.Moderate retention forestry creates structurally sharp forest edges that act as ecological filters, shaping orientation‐specific activity of ground‐dwelling arthropods. Using drift‐fence pitfall traps, we show that activity aligned with ecotones is more frequent than activity across forest–clearcut boundaries, particularly among detritivores.

Integrative Zoology, EarlyView.We study that browsing by wapiti reduces the growth of saplings, and it develop chemical defenses to prevent themselves browsed again. These results reduce our concern about wapiti browse T. cuspidate saplings, and provide basic data for the study of the interaction between them, and also provide theoretical basis for the population restoration and ...

Variation in reproductive potential across a multi-species treeline
Arctic, Antarctic, and Alpine Research, 2018 Cone and seed production at the forest-tundra ecotone, or treeline, depend on species-specific tolerances to limiting abiotic and biotic factors. As range expansion via seed dispersal is needed to keep pace with climate change, reproductive limitations ...

Warm Spring Weather Alters Calling Phenology of Four Sympatric Early‐Breeding Anurans
Integrative Zoology, EarlyView.An unusually warm March in 2024 (“false spring”) followed by freezing temperatures allowed us to assess the impact of a weather event on an amphibian community. The calling activity of all four species was associated with increasing temperature, and the first date of calling was advanced by 11–18 days.

Seasonal Habitat Selection by a Threatened Ungulate in an Industrializing Boreal Landscape
Animal Conservation, EarlyView.Understanding habitat selection by Threatened wood bison in landscapes characterized by anthropogenic disturbance is important for conservation planning. During summer and winter, bison selected for linear (e.g., roads, seismic lines, pipelines) and polygonal (e.g., well sites) disturbances, unless there were high densities of linear features.

Analyzing and modelling effects of climate on site productivity of white spruce plantations
The Forestry Chronicle, 2018 Effects of climate on site productivity of white spruce (Picea glauca) plantations were examined. Stem analysis data collected from 93 dominant or co-dominant white spruce trees sampled from 93 plots (1 tree/plot) in even-aged monospecific plantations on

Genomic selection in White Spruce
, 2017 Tree improvement programs are long-term and resource-demanding endeavors consisting of repeated cycles of breeding, testing, and selection and suffer from protracted testing phases. Phenotypic selection is commonly practiced and often requires trees reaching certain age and/or size resulting in slow accumulation of genetic gain.

Archaeometry, EarlyView.ABSTRACT With northern regions warming at twice the global rate, assessing the state of archaeological sites in these areas is critically important. In this study, we used a multimethod geophysical approach (ERT, GPR, and EMI) to characterize the current geocryological conditions of an Inuit archaeological site on South Aulatsivik Island (Labrador ...

Boreas, EarlyView.The characteristics of settlement of Neanderthals in northern Central Europe during the earlier phases of the Middle Palaeolithic (Marine Isotope Stage 8–6) have been a matter of debate for decades, specifically regarding the population dynamics at such latitudes during the coldest phases. In this paper, we review the known archaeological record of the
