Conifer host identity shapes wood‐boring beetle communities more than climate across a latitudinal forest gradient in Quebec (Canada)

Insect Conservation and Diversity, EarlyView.
Host tree identity and latitude shaped wood‐boring beetle assemblages, with species richness declining northward but community composition varying among regions and hosts. Host tree species influenced beetle communities more strongly than climate; black spruce supported the most species, while eastern hemlock hosted very few.

Relative contributions of site conditions and interspecific competition to post-harvest regeneration in boreal mixedwoods

The Forestry Chronicle
In Canadian boreal forests, clearcutting has traditionally been the main harvest treatment, resulting in relatively uniform, even-aged stand structures.

Somatic Embryogenesis and Plant Regeneration From Primordial Shoot Explants of Picea abies (L.) H. Karst. Somatic Trees

Frontiers in Plant Science, 2018
The recalcitrance of adult conifer tissues has prevented vegetative propagation of trees with known and desired characteristics. Somatic embryogenesis (SE) initiation protocol, recently developed for white spruce (Picea glauca, Klimaszewska et al., 2011),

Desmin is not ubiquitously expressed in head and neck muscle fibers

Journal of Anatomy, EarlyView.
Desmin is not ubiquitously expressed in human head and neck muscle fibers. A subset of fibers showed absent or very weak desmin immunoreactivity, with corresponding reduction or absence of desmin mRNA expression. Abstract Desmin, a major muscle‐specific intermediate filament protein, is widely regarded as a ubiquitous component of mature skeletal ...

Temporal variations in English Populations of a forest insect pest, the green spruce aphid (Elatobium abietinum), associated with the North Atlantic Oscillation and global warming [PDF]

, 2007
Based on an exceptionally long modern ecological dataset (41 years), it has been possible to show that warm weather in England associated with a positive North Atlantic Oscillation (NAO) index causes the spring migration of the green spruce aphid ...

Transforming Management Education: Insights from Social‐Ecological Systems and Social Innovation Research

Journal of Management Studies, EarlyView.
Abstract It is clear that contemporary management education (ME) needs to be transformed to tackle complex social‐ecological crises effectively. However, the concept of transformation is often ill‐defined in the context of ME; while there is also a lack of understanding about what concrete transformation trajectories (also called scaling pathways) are ...

A phylogenomic approach for a new infrageneric classification of Bulbostylis (Abildgaardieae, Cyperaceae)

Journal of Systematics and Evolution, EarlyView.
In this study, we investigate the relationships among 149 species of Bulbostylis (Cyperaceae)—representing 69% of global diversity—using a universal probe kit for targeted genomic sequencing of flowering plants (Angiosperms353 probe kit). Our sampling also includes the genus Nelmesia, which we found to fall within Bulbostylis.
