Abstract:
Twenty open-pollinated families of jack pine (Pinusbanksiana Lamb.) were grown for 16 to 21 months in two different greenhouse regimes, one providing an extended growing season with natural photoperiod and one employing control of temperature and photoperiod to accelerate growth cycles. Height measurements during and at the end of greenhouse growth were compared with height of 7-year-old seedlings of the same families growing in field tests. For both greenhouse regimes, height at the end of the second growth cycle was positively correlated with 7-year field height. Greenhouse measurements correctly classified the majority of families into upper and lower groups based on field heights. Early family selection in jack pine appears to have applications in long-term breeding strategies.

Abstract:
Purpose – This article aims to propose that increased guidance on the implementation of social marketing principles for sustainability issues can advance both implementation and empirical evaluation. The primary goal of this paper is to ignite further empirical investigation of social marketing for sustainability by first presenting benchmark criteria for one social marketing model – community-based social marketing (CBSM) – and second, applying this framework to the case study of musician Jack Johnson’s “All at Once” (AAO) campaign. Design/methodology/approach – The research design is twofold. First, based on Doug McKenzie-Mohr’s CBSM model, a series of 21 benchmarks for assessing the key components of an effective CBSM initiative was developed. Second, this tool was applied to information gathered from Jack Johnson’s extensive outreach promoting AAO initiatives including reports, videos as well as interviews and in-person meetings with the Jack Johnson team. Findings – Application of the benchmark criteria to the Jack Johnson case study showed that seven out of the 21 benchmarks were integrated into the AAO campaign; seven were partially integrated and seven were not integrated in the program’s design. In particular, the use of commitments, incentives, norms and social diffusion was clearly present as was a final evaluation of the full-scale implementation of the campaign. Originality/value – The CBSM benchmarks are meant as a starting point to further assess and compare the effectiveness of CBSM initiatives. Further research should be done to explore how criteria should be weighted and which of the 21 principles need to be present in the design and implementation of an effective CBSM program.

Abstract:
Cold-stored jack pine (Pinusbanksiana Lamb.) and white spruce (Piceaglauca (Moench) Voss) seedlings were planted in a controlled environmental chamber providing an air temperature of 22 °C and soil temperatures of 22, 16, or 10 °C. After 21 days, observation of root growth for white spruce seedlings was limited at all soil temperatures, whereas jack pine seedlings showed limited root growth at a soil temperature of 10 °C but not at 22 °C. During 21 days of observation after removal from cold storage, stomatal response patterns changed during the transition phase from darkness to first light. Jack pine seedlings showed increasing stomatal opening at first light with greater stomatal opening for seedlings in the 22 °C root-temperature treatment, while all white spruce seedlings exhibited a greater stomatal closure during darkness. In both species, seedlings at lower soil temperatures experienced greater initial water stress than seedlings at higher soil temperatures, the difference being associated with a greater water-flow resistance through the soil–plant–atmosphere continuum (SPAC). In both species, xylem pressure potentials increased with time at all temperatures; a change attributable to a decline in water-flow resistance through the SPAC. The decline in water-flow resistance was possibly due to either a change in the permeability of older suberized roots or, as in jack pine at the higher soil temperature, a significantly greater development of new unsuberized white roots.

Abstract:
Background. The injured anterior cruciate ligament (ACL) has a limited healing capacity leading to persisting instability. Hypothesis/Purpose. To study if the application of a brace, producing a dynamic posterior drawer force, after acute ACL injury reduces initial instability. Study Design. Cohort study. Methods. Patients treated with the ACL-Jack brace were compared to controls treated with primary ACL reconstruction und controls treated nonsurgically with functional rehabilitation. Measurements included anterior laxity (Rolimeter), clinical scores (Lysholm, Tegner, and IKDC), and MRI evaluation. Patients were followed up to 24 months. Results. Patients treated with the ACL-Jack brace showed a significant improvement of anterior knee laxity comparable to patients treated with ACL reconstruction, whereas laxity persisted after nonsurgical functional rehabilitation. The failure risk (secondary reconstruction necessary) of the ACL-Jack group was however 21% (18 of 86) within 24 months. Clinical scores were similar in all treatment groups. Conclusion. Treatment of acute ACL tears with the ACL-Jack brace leads to improved anterior knee laxity compared to nonsurgical treatment with functional rehabilitation.

Abstract:
Plant competition is expected to produce an overdispersed spatial pattern relative to the initial pattern of individuals. The spatial patterns of two boreal forest tree species, Populus tremuloides Michx. (trembling aspen) and Pinus banksiana Lamb. (jack pine), were examined for evidence of intraspecific and interspecific competition. Data consisting of species, position, and age of tree stems were obtained from a 21-year-old, 40 m × 30 m postfire area of boreal forest in northern Alberta, Canada. Tree stems were mapped and classified according to size (greater or less than 5 cm in diameter at ground height) and species. A variation on the random mortality hypothesis was used to detect overdispersed patterns indicative of competitive interactions. This was done by comparing the size of neighbouring stems with those expected when the size or "success" of a stem occurred randomly. The results showed roughly two scales of pattern. First, large seed-regenerating jack pine neighboured each other more often than expected, but jack pine and trembling aspen neighboured each other less than expected. Second, although the large jack pine appeared to be clustered as neighbours, they tended to associate at distances farther than expected. These results show little evidence of density-dependence patterns in the species at the site, and the interspecific association between jack pine and trembling aspen could be indicative of a heterogeneous habitat.Key words: triangulation, size variability, Pinus banksiana, Populus tremuloides, jack pine, trembling aspen.

Abstract:
Light-saturated photosynthesis following artificial frosts was monitored for black spruce (Picea mariana (Mill.) BSP), jack pine (Pinus banksiana Lamb.), and trembling aspen (Populus tremuloides Michx.). None of the species exposed to -9°C in May or to -6 and -9°C in August recovered within the 23- and 14-day monitoring periods, respectively. Black spruce and jack pine treated at -6°C in May recovered within 5 and 23 days, respectively. Black spruce treated at -3°C in August recovered within 10 days. Frosts were applied to the upper and lower canopies of mature black spruce and jack pine in June and to mature trembling aspen in July. For black spruce, the lower canopy did not recover whereas the upper canopy partially recovered over the 10-day monitoring period. For jack pine and trembling aspen, there were no differences in recovery between canopy levels. Jack pine treated at -5.5°C recovered within the 10-day monitoring period whereas at -8.5°C, it only partially recovered. Although recovery period varied with species, phenological state, and frost temperature, gradual recovery of photosynthesis over 5-21 days seems a reasonable modelling algorithm for boreal tree species when growing season frosts lower than -3°C occur. However, cooling rates in our experiments were greater than those that normally occur in nature.

Abstract:
Macronutrient concentrations (N, P, K, Ca, and Mg), ash, high heat, and ash-free high heat contents were determined for current-year jack pine (Pinusbanksiana Lamb.) foliage, huckleberry (Gaylussaciabaccata (Wang.) K. Koch.) and blueberry (Vacciniumangustifolium Ait.) foliage, and reindeer lichen (Cladoniarangiferina (L.) Web.) thallus in four fire-regenerated jack pine (Pinusbanksiana Lamb.) stands in northeastern New York aged 21, 29, 46, and 67 years. Macronutrient concentrations and heat contents were usually lowest in lichen, but other species patterns differed with the variable. Overall, differences in macronutrient concentrations for each species in an age sequence were not significant. Comparisons of live aboveground understory biomass, macronutrient content, and heat content through the age sequence showed no significant differences, but the influence of stand age may have been masked by large spatial variability. If the wildfires that regenerated these jack pine stands caused serious nutrient losses, the adverse effects were no longer detectable with the methodology used in this study.
