Abstract: Clearcutting strongly affects subsequent forest net ecosystem productivity (NEP). Hypotheses for ecological controls on NEP in the ecosystem model ecosys were tested with CO(2) fluxes measured by eddy covariance (EC) in three post-clearcut conifer chronosequences in different ecological...

Cevallos-Ferriz, S., Stockey, R.A.
Some of the most conspicuous fruit and seed remains from the Middle Eocene Princeton chert locality (Allenby Formation) are assignable to the Araceae. Several thousand campylotropous, reniform, spiny seeds 2.5-3.2 mm long x 1.8-2.3 mm wide have been found dispersed in the chert. Two fruits, each...

The middle Eocene Princeton chert locality in southern British Columbia, Canada, contains one of the best-preserved permineralized Tertiary floral assemblages known in North America. The quality of pres- ervation of the vascular plant and fungal remains is exquisite because anatomical and...
