The Royal Catchfly (Silene Regia; Caryophyllaceae) In Indiana, Rebecca W. Dolan Jun 2010

The Royal Catchfly (Silene Regia; Caryophyllaceae) In Indiana, Rebecca W. Dolan

Rebecca W. Dolan

Botanist Thomas Nuttall called the royal catchfly, Silene regia, "one of the most splendid species in existence." This red-flowered, hummingbird-pollinated member of the Caryophyllaceae is a perennial herb of prairies and glades. Because of the conversion of much of its former habitat to agriculture, the royal catchfly is considered threatened in Indiana. The species' historical and present-day distribution in the State, documenting the current status of all known locations, including population sizes and co-occurring species, are reported in this paper. Only 8 of the documented 23 historical locations still support the plant. No populations occur in dedicated nature preserves or …

Conservation Implications Of Genetic Variation In Three Rare Species Endemic To Florida Rosemary Scrub, Rebecca W. Dolan, Rebecca Yahr, Eric S. Menges, Matthew Halfhill Mar 2010

Conservation Implications Of Genetic Variation In Three Rare Species Endemic To Florida Rosemary Scrub, Rebecca W. Dolan, Rebecca Yahr, Eric S. Menges, Matthew Halfhill

Rebecca W. Dolan

Habitat conversion and fire suppression during the last 50 yr have greatly reduced and altered Florida scrub vegetation, resulting in threats to the persistence of its unique flora. As part of a larger conservation project, we investigated patterns of isozyme variation in three rare perennial scrub plants with overlapping ranges endemic to Florida rosemary scrub on the Lake Wales Ridge. All three species have low levels of genetic variation, comparable to or lower than those generally reported for rare plants with restricted geographic ranges. Liatris ohlingerae has more than twice the expected heterozygosity of the other two species, with little …
