Description of research project: Continuation of previous research conducted by Dr John Gamon, relating plant optical properties (spectral reflectance) to physiological properties. Besides measuring spectral reflectance, other non-destructive tests will include plant gas exchange (measuring CO₂ absorbed vs water transpired). The overall purpose of the research is to determine the relationship (if any) between the optical reflectance and the amount of water transpired by the plant.

Existing plots will be resurrected with removal of dead plant species and repair (if needed) of existing irrigation system. Potential future planting of additional non-invasive, native California plant species in empty plots may occur. Permission will be obtained before introducing additional species.

Description of research project: I propose to study how maximal sprint performance plays out on the ecological level. Lizards rely on sprint speed to escape from predators. But there is a two fold variance in lizard sprint speed, meaning that slower lizards must compensate by adopting other strategies. One possible strategy is for lizards to start escaping sooner (i.e., lengthen predator approach distance). I will investigate this relationship by comparing lizard sprint speed with approach distance.

My previous work in statistics illustrated that performance factors, such as sprint speed, not only vary between individuals but vary within individuals. Indeed half of the variation in sprint speed results from within individual variation. I expect approach distances to show a greater within individual variation than sprint speed.

This work is important from a bio-statistics perspective because a low intra-class correlation coefficient (repeatability) severely reduces the reliability of estimated correlations. I intend to work with Dr. Adolph and Dr. Johanna Hardin to develop and employ a correction factor to better estimate the correlation between approach distance and sprint speed.

I will capture about 20 adult Sceloporus occidentalis from the upper reaches of the botanical gardens. These lizards will be run to determine maximum sprint speed on the Harvey Mudd lizard race track five times per individual. An associate will mark the lizards with beads so that I am blind to the results for the rest of the experiment. The lizards will be returned to the original location in the botanical gardens.

In the subsequent months, I will make five approaches at each of the twenty lizards. The approach distance (closest possible distance I reach before the lizard flees) and the flight distance (farthest distance the lizard runs) will be recorded. I will then recapture all lizards and measure the maximal sprint speed as before.

Will plants or animals be collected? yes

Description of research project: The green lynx spider Peucetia viridans (Hentz 1832) is the largest and most common member of the family Oxyopidae, with a distribution throughout the southern United States, Mexico and Central America (Brady 1964). It is a diurnal, visual hunter which forages on plants, especially on flowers, where it lies in ambush for potential prey (Comstock 1948; pers. observ.). Concerning its reproductive biology, Brady (1964) found (via microscopic examination of preserved specimens) that the two openings of a mated female’s epigynum were usually plugged with a hard, black material. Brady suggested that the black material must be deposited during or immediately after insemination and reasoned that the plugging of the female epigynum should prevent further mating by the female. More recently, Huber (1995) noted that another function of spider epigynal plugs may be to seal off the otherwise open genital orifices following mating to prevent desiccation, implying that they should be more common in populations which occupy drier settings. Ramirez et al. (2006) recently reported data for P. viridans consistent with this hypothesis, as they found an absence of plugs at a single coastal site as compared with their commonness at two more inland Los Angeles Co. sites. Given this context, my purpose in requesting access is to include P. viridans from the BFS (they are common on buckwheat) in an extensive survey of plug presence among females from coastal sites vs. dry, inland sites, in order to expand on the findings of Ramirez et al. (2006).

Number in research group: 10
Dates: 10/24/2006 to 06/01/2007
Frequency: Several-days/week
Time of day: Dawn, Morning, Evening
Areas to be used: central CSS, eastern CSS, oak forest, south field, lower neck
Facilities or equipment needed: None
Will any plant or animal species be studied? yes - Zonatrichia leucophrys (White-crowned sparrow)
Melospiza melodia (Song Sparrow)
Aphelocoma californica (Scrub jay)
Pipilo fuscis (Brown Towhee)
as well as other residents and migratory passerines
Will plants or animals be collected? no
Will vertebrate animals be collected or manipulated? yes
Will markings or flags be used? yes - 4-6 mist nets will be rolled up and tied to poles to be opened when we are banding.

Description of research project:
The purpose of this project is to:
1) determine if the wintering flocks of white-crowned sparrows return to the study area on an annual basis,
2) ascertain their length of residency time,
3) determine the habitat that they utilize while they are here,
3) assess winter survival rates,
4) monitor their condition throughout the winter, in particular, to see how fat reserves increase/decrease with time of year and weather patterns, and
5) examine wintering flock behavior looking at group size, membership and activity patterns.

Methods:
We will band White-crowned Sparrows with a metal numbered band and individual color band combinations as they arrive. We will take all the standard morphometric measurements when we first capture them. We will resight them throughout the winter noting the habitat they are found in, their behavior and who they are associated with. When we recapture birds, we will weigh them and note the amount of fat in their furculum. We will look for them in the following years. This will be a multi-year study. The re-sighting will be done with the help of 10 undergraduate students from the Claremont Colleges, which border the field station.

Secondary purposes of the study:
1) to assess the timing and extent of migration of passerines during fall and winter. It is likely that we will catch migrants in our mist nets. These birds will be banded and measured and released. These data will be used by senior thesis student Julia Goldstein (Pomona College ’07).

2) to band and measure other resident birds at BFS. We will likely capture Scrub Jays, Brown Towhees and Song Sparrows in our mist nets. With the accumulation of a marked population at BFS, we will be able to assess population changes of residents. Data on body condition will be taken at every recapture to assess changes in health seasonally and over different years.

Description of research project: Members of the barberry family including Nevin’s barberry, Berberis nevinii, produce the antibiotic agent berberine. The purpose of this project is to determine if berberine resistant bacteria are selected for in the soil surrounding Berberis nevinii bushes. Soil samples will be taken in the vicinity of several B. nevinii bushes and plated on media with and without berberine. Preliminary tests will determine the necessary concentration of berberine to produce inhibition of certain bacteria. Further experiments will investigate the proportion of berberine resistant bacteria in the soil under B. nevinii with soil elsewhere. Additionally, characterization of the resistant bacteria will be performed.

Will plants or animals be collected? Yes
Will vertebrate animals be collected or manipulated? No
Will markings or flags be used? No

Description of research project: The harvester ant is a common insect west of the Mississippi river, and over 26 different species populate the Western United States. Study of the pheromones produced by the ants can give insight into the life of an ant in terms of how it forages, lays a trail for fellow workers, etc; it also provides utility in developing pest control methods. The purpose of this study is to characterize the pheromone structure of the harvester ant species Pogonomyrmex californicus, compare the major pheromone structure/components to other species of genus Pogonomyrmex, and possibly test isolated compounds(s) for biological activity.

Specimens of Pogonomyrmex californicus will be keyed to verify local species. Once this is complete, samples of P. californicus will be taken and the pheromone structure determined by extraction of the natural products from the specimen and subsequent characterization via common organic laboratory analytical techniques (including but not limited to high pressure liquid chromatography, gas chromatography, mass spectrometry, etc.).

Description of research project: I propose to study the utilization of pHake Lake as a stop-over point for migratory birds during their Fall and Spring migrations. Numerous species of migratory birds fly over Claremont on their south-bound migrations in the Fall and north-bound migrations in the Spring. I will identify species and abundance of migratory birds that rest at pHake Lake. This study will evaluate the use of pHake lake during migrations and will highlight the importance of the conservation of wetlands along their migratory routes.

In order to do this I plan to visually survey birds in and around the lake five mornings per week. I will conduct research between 6:30 and 8:30 am. All observations will be made via binoculars or a scope, and I will use a field guide to make identifications.

Description of research project: Foraging behavior is often used to gain insights into ecologically important variables such as food value, habitat use, and predation risk. Charnov’s Marginal-Value Theorem predicts that a forager will quit foraging from a patch that yields diminishing returns when the energy gain from foraging equals the fitness costs of foraging. We want to use this idea to compare food types for California ground squirrels.

Goal: Measure and compare food value of different foods, e.g., sunflower seeds vs. wheat vs. chick peas, food treated with tannic acid vs. food without tannic acid treatment, food treated with oxalic acid vs. food without oxalic acid, and food that is more cacheable vs. food that is less cacheable (e.g. sunflower seed in their shell vs. out of their shell).

Description of research project: The purpose of the project is to develop and validate optical and thermal sampling methods for estimating surface-atmosphere fluxes of biologically and radiatively active gases (CO₂ and water vapor, in this case) - the “breathing of the planet.” To do this, we would install an eddy covariance tower (large tripod with meteorological instruments to measure surface-atmosphere gas fluxes) and a tram system (robotic cart on a 100-m track) to measure ecosystem optical and thermal properties. The project is part of SpecNet (http://specnet.info/) and FLUXNET (http://www-eosdis.ornl.gov/FLUXNET/) networks, and is funded by National Science Foundation (Ecosystems and CREST) grants to John Gamon. Our initial goal would be to setup and test the instruments at this site for possible deployment elsewhere. Depending upon the quality of the site and measurements, we may choose to ask for indefinite access (a more-or-less permanent site).

Project description: Students will be comparing the habitat preferences of the two species of woodrats that are at BFS. I will be attaching small, removable radio collars to woodrats. The students will relocate the rats several times a week. They will map their locations and will measure vegetation characteristics where rats are found. Traps for woodrats will be placed in the evening and checked several times during the night to ensure that no rats are sitting there too long. After capture they will be weighed and sexed, fitted with the radio collar and given a PIT tag. This is a small injected tag that reads like a bar code. This method is preferable to ear tags because ear tags often get pulled out and rip the ears of the rat. All the protocols have been approved by the Fish and Game for both species. Students will be responsible for relocating the rats while they are out foraging. They will need access to BFS at dusk and at night (this is one reason why I want to use BFS, it is safer than sending them elsewhere). These are all advanced biology students who are familiar with BFS and its rules. Students will also make maps of all the woodrat houses that they can find. It is my hope that this project will continue throughout the summer and next fall. Woodrats will be recaptured to remove the radio collars when the batteries start to run out.
