Community structure at local scales is a major factor controlling population and community dynamics of plant species. Dicerandra immaculata Lakela var. immaculata (Lamiaceae) is a critically endangered plant known only from a few locations in scrub habitat in Florida. Using seven sites where populations of D. immaculata were wild, introduced, and/or(More)
The composition and antacid properties of 10 samples of crystalline antacids containing both aluminum and magnesium were determined. The composition was found to vary significantly, even within the same type of antacid. For example, three of four hydrotalcite samples exhibit evidence of the presence of a minor phase of amorphous aluminum hydroxide. Almagate(More)
PREMISE OF THE STUDY Microsatellite primers were developed in scrub lupine (Lupinus aridorum, Fabaceae), an endemic species to Florida that is listed as endangered in the United States, to assess connectivity among populations, identify hybrids, and examine genetic diversity. METHODS AND RESULTS We isolated and characterized 12 microsatellite loci(More)
Understanding reproductive systems of rare plants is critical for conservation efforts. Lakela’s Mint, Dicerandra immaculata Lakela var. immaculata, is an endangered plant endemic to an approximately 4.8-km long area in Florida, USA. We used an experimental garden and three populations of Lakela’s Mint to determine: (1) what is the breeding system(More)
Species previously unknown to science are continually discovered and some of these species already face extinction at the time of their discovery. Conserving new and rare species in these cases becomes a trial-and-error process and conservationists will attempt to manage them by using knowledge of closely related species, or those that fill the same(More)
Elucidating microhabitat preferences of a rare species are critical for its conservation. Lupinus aridorum McFarlin ex Beckner (Fabaceae) is a critically endangered plant known only from a few locations in imperiled Florida scrub habitat and nothing is known about its preferred microhabitat. Our goals were threefold. First, determine whether L. aridorum has(More)
The composition and antacid properties of six samples of codried antacids containing both aluminum and magnesium were determined. Aluminum hydroxide–magnesium carbonate codried gel and aluminum hydroxide–magnesium hydroxide codried gel were non-homogeneous, as the samples contained combinations of hydrotalcite, amorphous aluminum hydroxide, magnesium(More)
Conservation measures to preserve critically endangered species aim to maintain healthy and self-sustaining populations and often involve reintroductions. Effective introductions must take into account the genetic structure and diversity remaining in the species to inform choices of germplasm for introduction strategies. Lupinus aridorum (McFarlin ex(More)
