The data are population sizes of yeast Saccharaomyces cerevisiae growth in laboratory cultures over a period of several days with different levels of growth inhibitor cycloheximide.

Old World Climbing Fern (Lygodium microphyllum (Cav.) R. Br.) is an invasive plant species threatening South Florida ecosystems. In 1989 L. microphyllum was observed in the Arthur R. Marshall Loxahatchee National Wildlife Refuge. L. microphyllum has attributes that allow it to thrive in South Florida. It produces a huge number of small spores that are easily suspended by wind and dispersed, have a high germination rate, and gametophytes have a high rate of sporophyte production. Aerial dispersal allows it to spread to suitable germination sites and its ability to self-fertilize at such high rates promotes successful colonization. The intense, abundant spore production also assists in saturating most suitable colonization...
This project directly addresses a recovery action in FWS’s recovery plan for the snail kite (Multi-species Recovery Plan for South Florida - Everglade Snail Kite, 1999), which recommends the development of modeling that can predict the response of snail kites to changes in hydropattern anticipated for specific water management proposals (recovery action H3.1). The proposed real-time models would be a significant first step in completing this recovery action, which specifies modeling that would include “...linkage to apple snail distribution and abundance, vegetation characteristics in the landscape influencing the snail kite’s successful foraging, and linkage of all these factors to hydrology.” In addition, this...

This SSP project conducted from FY2002-2006 had several parts: The optimal control model portion which was worked on by Scott Duke Sylvester for his dissertation research. A spore dispersal study conducted by Allison Snow (USGS employee based at the Arthur R. Marshall Loxahatchee NWR) A spore germination study conducted by Erynn Call (USGS employee based at the Arthur R. Marshall Loxahatchee NWR) A user interface for Scott's model done by Gareth Mann and Leonard Pearlstine, University of Florida. An analysis of Lygodium in the refuge from IKONOS data done by Ken Rutchey at South Florida Water Management District. The first and last projects were not funded with SSP funds, but are considered part of the project....

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
