Assessment of Recent Habitat Conditions of Eastern Oyster Crassostrea virginica Bars in Mesohaline Chesapeake Bay
Between 1999 and 2001, an acoustic seabed classification system and underwater videography were used to assess oyster habitat conditions throughout Maryland's portion of Chesapeake Bay relative to eastern oyster recruitment and habitat restoration activities. Expand
Factors Limiting Distribution and Size in the Starfish
In shallow water of Malpeque bay, P.E.I., the distribution of the starfish Asterias vulgaris, Verrill, is limited by temperatures over 25 °C. in the summer and salinities less than 14 per mille inExpand
Geographical variation in the major compounds of Aloe ferox leaf exudate.
Geographical variation in fresh Aloe ferox leaf exudate, of which the dried product is commercially known as Cape Aloes, was investigated throughout the natural distribution range of the species, finding no distinct geographical discontinuities. Expand
Therapeutic uses of Aloe L. (Asphodelaceae) in southern Africa.
The exceptional infrageneric diversity of Aloe, and extensive therapeutic uses in southern Africa, indicate its cultural importance in the subcontinent and highlight the need for the conservation of the species as well as their potential as a source of natural products. Expand
The location, composition, and origin of oyster bars in mesohaline Chesapeake Bay
Sub-bottom profiling sonar surveys in the mesohaline Chesapeake Bay located pre-Holocene, hard terrace structures surrounded by or buried by softer sediments. The descending scarps of these hardExpand
Post-disturbance spruce-fir forest stand dynamics at seven disjunct sites
Forests dominated by red spruce (Picea rubens Sarg.) and Fraser fir [Abies fraseri (Pursh) Poir.] occupy the highest elevations of the southern Appalachians. These forests have been severely impactedExpand
Notes on the genus Frithia (Mesembryanthemaceae) and the descrip­ tion of a new species, E humilis, in South Africa
The two window-leaved species of Frithia N.E.Br (Mesembryanthemaceae), formerly thought to be a monotypic genus, has been found to comprise two species, and morphological differences between the roots, leaves, flowers, pollen, capsules and seeds are discussed. Expand
Remote Acoustic Habitat Assessment Techniques Used to Characterize the Quality and Extent of Oyster Bottom in the Chesapeake Bay
Underwater acoustic technologies may be used for remote sensing of estuarine and coastal benthic habitat in addition to more traditional methods of assessing the seabed. These systems use reflectedExpand
