Michael
Westphal
I am a Postdoctoral Research Associate
in the Gerber Lab. My areas of interest include: the application
of decision theory/optimization methods to conservation
biology, spatial ecological modeling, and ecological-economic
modeling. I am currently working on a Packard Foundation-funded
project evaluating the efficacy of marine reserves in
the Gulf of California, Mexico and the development of
a decision-support framework to explore management options
and explicitly incorporate both the "currencies"
of biological conservation and socioeconomics. I received
a PhD in Environmental Science, Policy and Management
from UC Berkeley in the Spring 2003, and my doctoral research
involved metapopulation modeling and optimal habitat reconstruction
for birds in the Mount Lofty Ranges, South Australia with
Hugh Possingham at the University of Queensland (http://www.ecology.uq.edu.au/research/mwestphal.htm).
I arrived at Arizona State University after a brief stint
at UFZ - Centre for Environmental Research in Leipzig,
Germany, where I was working on optimal mowing of butterfly
meadows (www.oesa.ufz.de).

My research focuses on the nexus between
conservation ecology and economics, specifically on how specific aspects
of ecological change can be incorporated into socioeconomic decision-making.
During my doctoral research, I conducted an ecological and economic assessment
of anthropogenic degradation to coral reefs in the northern Red Sea, and
proposed a system of charges for damages to the reef. I am currently studying
the economic costs and benefits of protecting specific areas in the Gulf of
California, and how the uncertainty of management alternatives may affect the
choices made by individuals in stated preference valuation exercises. I am also studying the effectiveness
of marine reserves on the recovery of fish populations and their benefits to
local communities.

I am interested in spatial and behavioral ecology of large mammals. I have recently joined the Gerber lab and hope to examine territorial male behavior, behavioral effects of relatedness, and how human disturbance impacts stress levels in California sea lions. My doctoral research focused on spatial ecology of coyotes. I specifically looked at how food dispersion affects coyote space use and territorial behavior. For my M.Sc., I evaluated territorial fidelity of male guanacos. I also evaluated behavior of territorial males to determine if females use male behavioral traits in secondary mate choice selection.

Marine reserves are advocated as strategies to protect reef fish stocks and promote marine conservation. Reserves are potentially useful because they can conserve and guard the ecological integrity of the reserve site while involving the community, increasing understanding of the ecosystem, and allowing an opportunity for reef fish stocks to achieve their full potential. To date, most reserve design scenarios have been largely drive by political motivations, rather than biological and societal needs. I focus on the N. Gulf of California ecoregion as a case study to develop conservation approaches that account for ecological and societal needs. In particular, I focus on predatory reef fishes and the sport fisheries that target them.
The objective of my project is to gather and analyze information on grouper and giant sea bass reproductive and ecosystem ecology. This knowledge is necessary to implement effective conservation measures in the Northern Gulf of California ecoregion.
Because current and increased levels of exploitation
could negatively impact Gulf of California fisheries and
ecosystem health, we must also identify current levels
of recreational fishing activity, and the impact of this
fishery on vulnerable fish species.

Graduate Student
My independent research focuses on the eastern North Pacific
gray whale population and how drastic changes in its abundance
relate to classification status under Endangered Species
Act criteria. Abundance estimates from over twenty years
of census counts are applied to a statistical probability
model that projects possible growth rates of a given species,
which can then be applied to ESA classification criteria
for long-lived vertebrates.

Neff
Graduate Student
Science is a powerful tool to help us make wise management decisions, but science cannot create policies. I am interested in how we as a society use science and scientific knowledge to make policy decisions. My interests lie in three areas: 1) United States science policy, 2) ecology, and 3) the links between scientific knowledge and decision making processes. I joined the Consortium for Science, Policy and Outcomes (www.cspo.org) in August, 2005 to work on their Science Policy and Research on Climate project. My research will focus on ecology and climate research policy.
I received a Masters degree from the
University of Oregons Environmental Studies Program where I
researched scenario planning as a way to make decisions in
uncertain and politically charged ecosystem management
disputes. My thesis was entitled Assessing Future Threats
to the Jackson, Wyoming/ National Elk Refuge
Social-Ecological System: A Scenario Planning Case Study.

I am currently researching management of several invasive
species looking at both the effectiveness and cost of
management efforts. This is part of a modeling project
by Leah Gerber and John Sabo to determine the effectiveness
of reducing variability of a population as a means of
management.

Kathy Robertson
Undergraduate Research Student
I am an undergraduate in the Conservation Biology program and have been
part of Dr. Gerber's lab for two semesters. I am broadly interested in
conservation biology, policy, population dynamics, political ecology,
sustainable development, and international affairs (specifically the UN
Convention to Combat Desertification). In Dr. Gerber's lab, my current research is on mapping the distribution of male territories using ArcGIS, in order to understand spatial clustering of males, spatial variation among the sites, and if variation changes throughout time. I also participated in the 2005 summer field season recording behavior data on sea lions at la Isla Granito

Britt
Undergraduate Research Student
I conscientiously make [relevant]
decisions in my life based on the impact on our surrounding environment. I share
the interests of many to study, protect, and enjoy earth's various forms of life
and the ecosystems in which they live. I'm a biology major with work experience
in teaching youth of the biology/ecology of the oceans. I've been involved with
the Gerber lab through field work since April '04 and currently, am working on
entering and analyzing data gathered from these research trips on California sea
lions and their behaviors.

Tiffany
Lewis
Undergraduate Research Student
My interests as an undergraduate are in conservation
biology, with a particular focus on marine ecosystems. I
would like to gain a better understanding of how as human
beings we can contribute to the conservation of marine ecosystems.
I would like to inform others of the importance of our influence
on the survival of these ecosystems. I am also working intently
on my scuba diving career in order to be able to study marine
life and ecosystems under the water as well as above.
Currently, in the lab, I am working on entering
and analyzing data gathered on the California sea lions
in the Gulf of California. I am learning behavioral patterns
as well as how important it is to keep track of these animals
in order to better understand them.

I am an undergraduate apprentice in Dr. Gerbers lab.
Currently, I am working on data gathered from this past
summer's field work on the California Sea Lion. My focus
for graduate school in the future will hopefully include
conservation biology.

Ashley Robota
Undergraduate Research Student
As an undergraduate I'm planning on graduating
with a degree in Biology. I'm interested in animal behavior,
and plan on attending veterinary school to further my studies
to research canine behavior. In the lab, I am entering Sea
Lion data collected during the summer of 2003 in the Gulf
of California. I hope that the data analysis skills that
I learn will assist me in furthering my education.

I'm a graduating senior here at ASU with a B.S. in Biology.
In the immediate future I hope to teach marine science to youth groups either
at a sea camp or an aquarium. Later I am planning to obtain a master's in zoology
with an emphasis on marine biology. My research interest is in elasmobranch behavior
and hope to eventually work as a shark biologist with the National Smithsonian Institute.

Bio 411 TA and Wolverine Populations
in North America
I'm a teacher's assistant for Bio 411 (Advanced Conservation
Biology) and concurrently working on preparing a population
viability analysis of wolverines in North America (with
partners Harriet Van Vleck and Duane Johnson). Data and
information about wolverines has been very limited in
the past because of the species' preference for secretive
and discrete lifestyles. We hope to add this PVA to other
available data for insight on the status of the species
populations. After graduation in December, I'm planning
to go on to graduate school, although the location is
still a mystery!

Work Study
I want to be a child psychiatrist or a pediatrician. I
am majoring in psychology but I’m basically pre-med.
I want to finish my undergraduate work here at ASU and
then go on to UCLA for medical school, or somewhere back
in California for sure. In the lab, I am working on entering
articles and papers into a database so they are easily
accessible and can be cited as sources easily. I’m
labeling and organizing them so that they are easy for
Leah to find and can be accessed whenever. I also find
resources at the library and do “little things”
that anyone needs done around the lab and such.

Cindi Girardin Marine reserves and pathogens
My project involves looking at marine pathogens in and
around marine reserves and how the presence of a pathogen
in a reserve might affect the efficacy of the reserve
with respect to the host population. In this case the
host population is fish. This study includes looking at
several different variables that may contribute to whether
or not the host population is affected and if so at what
point is it affected and to what degree. This study includes
several case studies to better explain the problems that
effect a reserve with the presence of pathogens

1) Mount Graham red squirrel
population viability analysis
2) Population Viability in Unstable Environments: Classifying
Endangered Species with the Diffusion-Approximation Model
I am working on population viability analysis (PVA) for
populations in changing environments. More specifically,
I am examining the effects of periodic fluctuations in
growth rates upon a simple model for predicting future
population growth. The diffusion-approximation model assumes
growth rates come from a consistent distribution, but
such consistency is rare in actual environments. I am
using simulated populations to determine in which range
and types of cyclic variation the model is still useful,
working towards applications with field data for fluctuating
populations. I have also done work on PVA for the Mt.
Graham red squirrel and modeling carrying capacity in
sea otters.

Acanthocephalans, sand crabs, and El Nino
Shorebirds and seabirds are definitive hosts for acanthocephalan
parasites. The acanthocephalan life cycle begins within
the sand crab and is completed within the shore bird.
Data in recent years suggests that sea otters have inadvertently
become part of the acanthocephalan life cycle. Research
has shown that the majority of acanthocephalan related
deaths in sea otters are due to pup and juvenile ingestion
of sand crabs. We hypothesize that the prevalence of acanthocepalan
parasites is correlated with the relative abundance of
sand crabs, and secondly that sand crab abundance is correlated
with sea surface temperature. My project is to examine
the relationship between sea otter mortality, warming
trends (e.g., increased frequency in El Niño events),
and sand crab abundance.

Ecology and Conservation of the Sonoran Desert
Tortoise
The desert tortoise (Gopherus agassizii)
occurs in the United States and Mexico in two main populations,
the Mohave Desert and Sonoran Desert populations. The
Mohave population is listed by the U.S. Fish and Wildlife
Service as threatened. While the Sonoran Desert population
is not listed as threatened at this time, it is protected.
Destruction and fragmentation of habitat are the main
factors affecting the Sonoran populations. While my specific
study is not yet defined, it will focus on some aspect
of the desert tortoise population in Arizona.

Marine reserves and monitoring
We are studying how current MPA’s are being monitored
and also looking at guidelines for how they should be
monitored. Through literature reviews, we are looking
at why MPAs should be successful, but at the time, are
not. We hope to come up with some general theories and
suggested guidelines for establishment of monitoring protocols
for MPA’s.

Designing MPAs for migratory marine
mammals
There are currently very few marine protected areas (MPAs)
that are exclusively designed for migratory marine mammals.
In my undergraduate honors thesis, I am looking at ways
of designing MPAs for migratory marine mammals, and how
management problems specific to these mammals may be solved.
I am looking at the different aspects of MPA design and
how the unique nature of migratory marine mammals requires
the integration of both current MPA models and new models
which take into account oceanographic and spatial issues
that are normally not an issue in current MPA design.
Through this research, I will present a model for creating
MPAs specifically for the conservation of large-scale
migratory marine mammals.
