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),

Changing climates and environments within the complex Middle to Late Pleistocene fill of an overdeepened valley at Niederweningen, Switzerland

Boreas, EarlyView.
Glacially overdeepened valleys in the northern Alpine Foreland preserve Middle to Late Pleistocene sedimentary sequences that may serve as valuable archives for reconstructing past environmental changes in response to shifts in climate. This study presents a multidisciplinary analysis of two sediment cores from the overdeepened Wehntal Valley at ...

Biological and chemical amelioration effects on the localities degraded by bulldozer site preparation in the Ore Mts. - Czech Republic

Journal of Forest Science, 2003
Biological and chemical (fertilising, liming) amelioration are among the principal tools used to restore degraded sites. These techniques were also used on the Ore Mts. plateau on plots prepared by bulldozing.

Integrating traditional practices, livelihoods, and conservation with Indigenous‐led furbearer camera trapping

Conservation Biology, EarlyView.
Abstract Contemporary conservation goals have a greater chance of success when practitioners collaborate with Indigenous communities. The importance of such collaborations has spurred calls by Western and Indigenous researchers to engage in equitable coproduction of ecological research that integrates multiple ways of knowing.

Nonhuman Pedagogical Relations: Towards Conceptual Limits

Educational Theory, EarlyView.
Abstract This article considers the pedagogical relation as a relation to a nonhuman educator, wherein the educatee is a member of the Homo sapiens species. My aim is to clarify the extent to which a nonhuman‐human relation can be understood as pedagogical.

Landscape and Geography Determine Saproxylic Beetle Captures in Pheromone‐Baited Traps

Entomologia Experimentalis et Applicata, EarlyView.
Pheromone‐baited traps at 39 forest sites across southern Sweden captured 58 saproxylic beetle species, including seven Red‐listed taxa. The effect of surrounding forest cover on beetle abundance may depend on latitude and longitude: positive effects were strongest in warmer southern and eastern regions but weakened or reversed in colder northwestern ...
