Ecological Genetics Of Melaleuca Quinquenervia (Myrtaceae) : Population Variation In Florida And Its Influence On Performance Of The Biological Control Agent Oxyops Vitiosa (Coleoptera: Curculionidae), F. Allen Dray Jr.
FIU Electronic Theses and Dissertations
Melaleuca quinquenervia (Cav.) Blake (Myrtaceae) was imported into Florida from Australia over a century ago as a landscape plant. A favorable climate and periodic wildfires helped M. quinquenervia thrive; it now occupies about 200,000 hectares in southern Florida. A biological control (i.e., biocontrol) program against M. quinquenervia has been initiated, but not all biocontrol releases are successful. Some scientists have argued that poor biocontrol agent success may relate to genetic differences among populations of invasive weeds. I tested this premise by determining (1) the number and origins of M. quinquenervia introductions into Florida, (2) whether multiple introduction events resulted in …

Effects Of Resource Limitation On The Essential Oil Production In Ledum Palustre Ssp Decumbens (Ait.) Hultén, Tracy A. Baldwin
Effects Of Resource Limitation On The Essential Oil Production In Ledum Palustre Ssp Decumbens (Ait.) Hultén, Tracy A. Baldwin
FIU Electronic Theses and Dissertations
To understand the relationship between resource limitation and essential oil production of the widely-distributed boreal/arctic shrub, Ledum palustre ssp decumbens, I documented naturally occurring variation of essential oils over a growing season with
field collections along a latitudinal transect spanning boreal forest to arctic tundra. Collections from a long-term resource manipulation experiment at a single tundra site served as a means of teasing apart those factors that might be influencing the essential oil production of the species. The essential oil composition varied significantly along the
transect in the number of detectable components, but the relationships among resources and essential oil …
