Type of use: Research
Number in group: 2
Dates: July 2002 to May 2003
Frequency: Several-days/week
Time of day: Dawn, Morning, Afternoon, Evening
Areas or facilities needed: western CSS, central CSS, pHake Lake, vernal pools, eastern CSS, oak forest, corner, infirmary, classroom, east field, lower neck, central neck, upper neck - Lizards will be collected in all areas of the field station. Enclosures for perch experiments are in area 10.
Species to be studied: Sceloporus occidentalis (Western Fence Lizard)
Will vertebrate animals be used? yes
Will markings or flags be used? no
Will plants or animals be collected? yes

Project description: We are studying habitat use and thermoregulation by western fence lizards. We capture lizards, measure them, take their body temperature, and record various features of their perch positions, them release them at the site of capture. We are also doing perch choice experiments in enclosures in area 10 (the east field). There are 7 enclosures (6 built in a previous year, plus one additional enclosure that we built this summer). We will release one lizard into each enclosure and observe its perch position over the course of one day. Following each trial, we will release lizards at their capture locations.

Type of use: Research
Number in group: 6
Dates: 5/18/02 to 12/31/02
Frequency: Weekly - Use will be unevenly distributed but averaging 1/wk
Time of day: Varies - times will depend on survey and time available for researchers
Areas or facilities needed: western CSS, lower neck, central neck, upper neck
Species to be studied: Study will be a survey of plant and animals using areas listed.
Will vertebrate animals be used? yes
Will markings or flags be used? yes - 33 3x3 m plots will be marked with flags at each corner. 30 plots will be in the neck, 3 in the western CSS.
Will plants or animals be collected? yes

Project description: The study asks what information about important ecological interactions can be gained from species lists. We will address two specific questions based on species lists from several taxa in replicated plots. First, can we use correlations of presence/absence data to infer ecological interactions that are important in shaping communities (e.g. keystone species). Second, how do species-area relationships differ among taxonomic groups, and how do these differences affect our ability to predict regional species diversity from species diversity at smaller scales. Parts of some plants and invertebrates will be collected to identify species composition within each plot.

College phone: 621-8601

Type of use: Research
Number in group: 1-4
Dates: Dec 2000 to ongoing
Frequency: Other - daily during winter; 1-3 times/week in spring, early summer
Time of day: Varies - varied times, daylight hours only
Areas or facilities needed: central CSS, eastern CSS, oak forest, infirmary, lower neck, central neck, upper neck
Species to be studied: Marah macrocarpus
Will vertebrate animals be used? no
Will markings or flags be used? yes - Flags mark individual plants. Two flag colors: White stake flags (2.5x3.5" flags; 15" stakes) and fluorescent pink stake flags (same type)
Will plants or animals be collected? yes

Project description: We are examining the population genetic structure and mating system of Marah macrocarpus. Leaf tissue and seeds are collected from marked plants for electrophoresis. The resulting data are used to estimate the level of inbreeding and to examine the extent of differentiation between spatially separated subpopulations. During winter 2002 and 2003, students will be examining the mating system through controlled cross- and self-pollinations.
