Type of use: Research
Number in group: 5-8
Dates: 4/19/03 to 4/19/03
Frequency: Once
Time of day: Morning, Afternoon - Start time: 10 am
Areas or facilities needed: central CSS, lower neck, central neck
Species to be studied:
Will vertebrate animals be used? no
Will markings or flags be used? no
Will plants or animals be collected? no

Project description: I am interested in the prospect of using the field station land area for formal training in archaeological field methods. I will be teaching related courses next academic year and, along with some students, would like to walk around the place for a few hours to assess such prospects. Mainly I am looking for a large land area with native vegetation on which to teach students how to survey for archaeological sites. This involves teaching students how to examine the ground surface for cultural materials, as well as how to use maps and compasses. No specimens will be collected, and the ground surface will not be disturbed.

Frequency: Once
Time of day: Afternoon
Areas or facilities needed: pHake Lake
Species to be studied: none
Will vertebrate animals be used? no
Will markings or flags be used? no
Will plants or animals be collected? no

Project description: The purpose of my project is to determine the levels of oxygen, hydrogen sulfide and bacteriochlorophyll at different depths in pHake lake. I will collect water samples from pHake lake, then test for hydrogen sulfide by titration and bacteriocholophyll by spectrophotometry of a 60% sucrose suspension of concentrated cells. Dissolved oxygen will be measured with a meter.

Type of use: Research
Number in group: 1
Dates: 1/29/03 to 4/30/03
Frequency: Other - perhaps weekly. likely only 3 or 4 times total
Time of day: Varies - it depends on when i can get there, usually in the afternoon before 5pm
Areas or facilities needed: pHake Lake
Species to be studied: Hyalella azteca
Will vertebrate animals be used? no
Will markings or flags be used? no
Will plants or animals be collected? yes

Project description: I am studying the effect of Acanthocephalan parasites on the behavior of the amphipod Hyalella azteca from pHake Lake for my senior thesis. There being very many of these in the lake, I only need to use a small amount of the shore to collect from, right near the road. I collect them and bring them back to the lab for behavioral experiments. I will need to drive to pHake Lake as the buckets are quite heavy when full, and I cannot carry them at the same time as the other equipment.

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: 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.
