We investigated aspects of germination and seedling establishment that might influence the distribution and diversity of Carex species growing in the forest understory. We tested the ability of Carex communis and C. platyphylla to germinate and establish at plots where adult individuals of one of these two species, or one of two other Carex species (C. backii and C. plantaginea), occurred in an...

OBJECTIVES To estimate the numbers of workers exposed to known and suspected occupational carcinogens in Canada, building on the methods of CARcinogen EXposure (CAREX) projects in the European Union (EU). METHODS CAREX Canada consists of estimates of the prevalence and level of exposure to occupational carcinogens. CAREX Canada includes occupational agents evaluated by the International Agenc...

Carex diaoluoshanica, a new species of Carex sect. Lageniformes from Hainan, China, is described and illustrated. The new species is similar to C. breviscapa but differs in having wider leaves with the leaf base gradually narrowed, 5-10 cm long and petiolelike, culms subfiliform, with only two spikes, the lateral female spikes from near the culm base.

OBJECTIVE The mixed orbicularis oculi muscle lacks an intramuscular proprioceptive system such as muscle spindles, to induce reflex contraction of its slow-twitch fibers. We evaluated whether the mechanoreceptors in Müller's muscle function as extrinsic mechanoreceptors to induce reflex contraction of the slow-twitch fibers of the orbicularis oculi in addition to those of the levator and fronta...

The name Carex poeppigii (sect. Echinochlaenae) is validated and a new combination in South American Carex, C. vixdentata (sect. Spirostachyae), is made here. Also, the taxonomic status of C. aueri is discussed, and this name is placed in the synonymy of C. reichei (sect. Arenariae).

The particular flood recessional ecosystem in Poyang Lake provides young and high quality grasses in late autumn and wintertime, and attracts millions of migratory birds to over winter. Grasslands along the lakes within Poyang Lake National Nature Reserve (NNR) have a remarkable phenology. So far, little attention has been paid to this dynamics of phenology. This thesis aimed to describe and in...

This study compared the orbicularis oculi muscle to the adductor pollicis muscle during vecuronium blockade. The orbicularis oculi muscle was found to be more resistant to and recovered from vecuronium neuromuscular blockade faster than the adductor pollicis muscle. Thus, caution should be utilized when assessing neuromuscular block with the orbicularis oculi muscle.
