  • foresters
  • Foresters need fast growing tree varieties that respond to market demands and provide high levels of resistance to environmental hazards (illness, drought, late or early frosts, etc. (irstea.fr)
  • Our expertise aims to help promote long-term genetic diversity of forest trees, choose the origin and improved reforestation varieties that provide the best compromise between performance and genetic diversity, and provide information to guide foresters in their choices without damaging local resources. (irstea.fr)
  • For three days, foresters, tree breeders, scientists, and practitioners met and listened to the excellent presentations that are summarized in these proceedings. (rngr.net)
  • Genomes
  • Bioinformatic analyses derived from RNA-seq of forest trees are particularly challenging, because the massive genome length (~20.1 Gbp for loblolly pine) and the absence of annotated reference genomes require specific bioinformatic pipelines to obtain sound biological results. (springer.com)
  • biology

  • growth
  • I had never heard the term 'forest bathing' until I stood in the old growth forest in MacMillan Park on Vancouver Island in British Columbia, Canada last month. (alamosanews.com)
  • We investigate the potential application of stable isotope analysis to cloud forest dendroclimatology at Monteverde in Costa Rica in order to be able to extract both chronological and paleoclimate information from trees without annual growth rings. (columbia.edu)
  • Demographic equilibrium theory explains tree abundances in terms of the scaling of growth and mortality. (nih.gov)
  • We use demographic equilibrium theory to derive analytic predictions for tree size distributions corresponding to different growth and mortality functions. (nih.gov)
  • In most forests, size distributions are much closer to the predictions of demographic equilibrium, and thus, intersite variation in size distributions is explained partly by intersite variation in growth and mortality. (nih.gov)

  • Lands which are used for horticultural purposes under a controlled agricultural plan whereby trees are grown from seedlings or planted saplings with their roots maintained in their natural state (not balled or otherwise packaged for sale). (ecode360.com)
  • destruction
  • In the final chapter, theauthor addresses the issue of genetic conservation -- a subject ofgreat concern in the face of accelerated forest destruction, industrialpollution, and climatic change. (whsmith.co.uk)
  • selection criteria
  • In parallel to this ongoing work, and within the context of climatic uncertainty, a far-reaching examination is being undertaken into the type and magnitude of changes that need to be made to the seed-tree population selection criteria as well as into usage advice for the various plant origins.

  • resistance
  • In the past decade, tree improvement programs were mainly focused on yield but it is obvious that enhanced stress resistance is also required. (frontiersin.org)
