The clonal shrub Cornus drummondii C.A. Mey. is rapidly increasing in cover and displacing mesic grassland species in the central USA as a consequence of fire suppression. We assessed the impact of C. drummondii on carbon (C) and nitrogen (N) pools and C fluxes in a tallgrass prairie in eastern Kansas, USA, through a comparison of both burned and unburned C. drummondii islands with open grassla...

Water supply and day length were varied in cold hardiness studies of red osier dogwood plants (Cornus stolonifera Michx.). The frost killing temperature, the content and freezing of stem cortical tissue water along with soil moisture content and tension were evaluated. Seven days of water stress in long and short day photoperiod regimes caused a rapid decrease in soil moisture content and plant...

 Assessing Bioretention Cell Function in a Midwest Continental Climate This study examined the performance of bioretention cells with five plant species: fragrant sumac (Rhus aromatica), yellow twig dogwood (Cornus stolonifera), buffalo grass (Buchloe dactyloides), switchgrass (Panicum virgatum), and daylily (Hemerocallis), and an unplanted control. Preliminary results indicate that switchgras...

We n&asured leaf respiration in 18 eastern deciduous forest tree species to determine if there were differences in tempera i m-respiration response functions among species or among c opy positions. Leaf respiration rates were measured in situ an4 on detached branches fordcerpensylvanicum L., A. rubrum i., Betula spp. (B. alleghaniensis Britt. and B. renta L.), Caryq glabra (Mill.) Sweet, Cornus...

We describe the mapping of the optical transfer function (OTF) of an incoherent imaging system into a geometrical representation. We show that for defocused traditional and wavefront-coded systems the OTF can be represented as a generalized Cornu spiral. This representation provides a physical insight into the way in which wavefront coding can increase the depth of field of an imaging system an...

Professor Cornel Tiberiu Opriş was the founder of the clinic for Oral and Maxillofacial Surgery, and also the first to teach this specialty in Cluj-Napoca in the first half of the twentieth century. Earlier in his profession, Dr. Cornel Opriş went from research into human physiology to practical activity in the field of surgery, to which he was more attracted. He was active both in research and...

Red osier dogwood (Cornus stolonifera Michx.) was artificially acclimated by exposing plants to 8-hour short days (SD) and low (15/5 C) temperatures for 54 to 63 days. Several factors including transpiration rate, stomatal resistance, and root conductivity were correlated so that the rate of water loss in acclimating plants was higher during the first 30 to 40 days of the acclimation sequence. ...

UNLABELLED PREMISE OF THE STUDY To facilitate genetic and conservation research of Cornus sanguinea, microsatellite loci were isolated and 29 individuals from 11 German populations were genotyped. • METHODS AND RESULTS Sixteen microsatellite loci were characterized from an enriched small insert genomic library. The number of alleles detected ranged from five to 11 per locus, observed heter...
