Ectomycorrhizal inoculated seedlings may improve forest plantation establishment by enhancing growth and nutrition of newly planted seedlings, but successful nursery colonization of planting stock is often incompatible with conventional fertilization practices because of toxic inhibitive effects. A new cultural technique for seedlings is examined, called "mycorrhizal nutrient loading" that integrates exponential high dose fertilization with ectomycorrhizal association without causing serious inhibition. Containerized black spruce ('Picea mariana' (Mill.) B.S.P.) were inoculated at sowing with 'Hebeloma crustuliniforme' or 'Laccaria bicolor ' and fertilized with a complete nutrient solution conventionally at 12.5 mg N/plant and exponentially at 12.5, 25 or 50 mg N/ plant representing conventional, loading and high loading application rates, respectively. At the end of nursery culture, exponential fertilization significantly stimulated ectomycorrhizal formation at higher rates (49-85%) than those of conventionally fertilized (22-26%) seedlings. Improved ectomycorrhizal colonization, even at high loading rates, was attributed to low initial nutrient additions and lower electrical conductivity levels maintained in the growing media under exponential fertilization. The gradual increase in nutrient delivery enabled the fungi to develop tolerance to high fertilizer inputs. Nutrient loading significantly increased N (51-135%), P (29-45%), and K (13-47%) uptake of seedlings, reflecting progressive luxury consumption of nutrients. Mycorrhizal inoculation further elevated loading efficiency by stimulating plant nutrient uptake of N (9-20%), P (7-12%), and K (4-18%), demonstrating accumulation was more efficient with fungal colonization. Vector nutrient diagnosis revealed marked nutrient dilution under conventional fertilization, but induced steady-state nutrition under exponential fertilization that benefited sustained symbiosis. When outplanted on bioassays retrieved from two contrasting boreal forest (Feathermoss and Hardwood-Alnus) sites in northern Ontario, mycorrhizal nutrient loaded seedlings outperformed conventional seedlings by enhancing dry matter production (45-92%), and increasing N (80-124%), P (89-129%), and K (72-106%) assimilation. The new growth drew on greater internal nutrient reserves built up by both exponential fertilization and mycorrhizal colonization in the nursery. Results were integrated into conceptual models demonstrating interactions of fundamental processes involved in mycorrhizal nutrient loading of trees and their resource utilization after planting in relation to different nutritional regimes. Given the current concern about adequate forest regeneration in Canada, nutrient loading in combination with mycorrhizal inoculation practices provides a potentially effective tool to improve early plantation establishment on boreal sites.

Traditional nursery culture of containerized black spruce ('Picea mariana' [Mill.] B.S.P.) seedlings involves a late-season hardening period when irrigation and fertilization are withheld to stress seedlings and promote frost-hardiness. Nutrient uptake is limited without supplemental fertilization, hence growth during hardening results in severe dilution of internal nutrients. The main objective of this study was to promote nutrient uptake and avert N dilution by fertilizing seedlings during the hardening period. Growth continues during this time (15-weeks), but gradually declines at the end of the rotation. Hence, nutrient supplementation progressively diminished with time to match seedling growth rate. Fertilization initially increased N uptake and elevated N concentration above initial pre-hardening status, but uptake declined after 6 weeks when fertilization ceased, causing growth dilution and N concentration decline. Based on these findings, fertilization dosages were increased and delivery schedules were prolonged in a follow-up experiment. Prolonged high-dose regimes promoted N uptake and prevented dilution, as reflected by a sustained increase of N concentration with time. When transplanted for 12-weeks on Boreal forest soil substrates to test outplanting performance, seedlings that received prolonged high-dose fertilization during hardening resulted in 115% more biomass and 350% more N than conventionally reared seedlings. The results demonstrate that fertilization during the hardening period improves early outplanting performance of seedlings, and may benefit future reforestation in northern forests.

The twelfth-century French poet Chrétien de Troyes is a major figure in European literature. His courtly romances fathered the Arthurian tradition and influenced countless other poets in England as well as on the continent. Yet because of the difficulty of capturing his swift-moving style in translation, English-speaking audiences are largely unfamiliar with the pleasures of reading his poems. Now, for the first time, an experienced translator of medieval verse who is himself a poet provides a translation of Chrétien’s major poem, Yvain, in verse that fully and satisfyingly captures the movement, the sense, and the spirit of the Old French original. Yvain is a courtly romance with a moral tenor; it is ironic and sometimes bawdy; the poetry is crisp and vivid. In addition, the psychological and the socio-historical perceptions of the poem are of profound literary and historical importance, for it evokes the emotions and the values of a flourishing, vibrant medieval past.

I have a dog. An inconvenient dog. When I wake up, my dog is inconvenient. When I'm getting dressed, my dog is inconvenient. And when I'm making tunnels, my dog is SUPER inconvenient. But sometimes, an inconvenient dog can be big and warm and cuddly. Sometimes, an inconvenient dog can be the most comforting friend in the whole wide world.
