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 ...

Entomologia Experimentalis et Applicata, EarlyView.Actia interrupta is an important larval tachinid parasitoid during low‐density populations of the eastern spruce budworm. In the late 1980s during the outbreak collapse, Meteorus trachynotus was initially the most important species, but was replaced by A. interrupta. Host patch size and density had no impact on the parasitism rates by A.

Peer Pressure: Do the Fitness Benefits of Animal Behavioral Traits Vary With Conspecific Density?
Ethology, EarlyView.We show that the activity of juvenile North American red squirrels influenced their survival in a density‐dependent manner: more active individuals had higher survival under high conspecific density, whereas less active juveniles had higher survival under low densities. Juveniles who were both more active and aggressive were more likely to survive. Our

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

Ibis, EarlyView.Natal dispersal is a key ecological process influencing gene flow, population connectivity and individual fitness. In altricial birds, the transition from fledging to natal dispersal is mediated by the post‐fledging dependence period, which is often difficult to observe in elusive, forest‐dwelling species.

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.
