I am
currently a senior in Wildlife and Fisheries Biology at Clemson
University. I have spent the last three
months participating in a Creative Inquiry (CI) project that focuses on the
effects of exurbanization
on salamanders in the Clemson
area. This Creative Inquiry really
interested me because my passion is endangered species and human impacts on
wildlife. The research we are doing
shows how exurbanization could be affecting salamander populations in first order
streams, which goes right along with my interest in human impacts on
wildlife.
Our Creative
Inquiry’s outings and research was led by graduate student Nathan Weaver. We started out having weekly meetings that
focused on gathering background information and learning about salamander
ecology. We would read and discuss
different scientific journals that we found on stream ecology, amphibian
ecology, and impacts of urbanization. Reading journals helped us get prepared
for field work and helped us to understand the proper way to set up a research
project. After we were well versified
we picked out streams within the Clemson area to start sampling in. We had one control and four urban sites.
Most people do not know what exurbanization is. Well, exurbaniztion is when people from an
urban area move to a rural area but still continue with an urban
lifestyle. When people move to rural
areas they usually don’t realize the impacts they can have on the environment. Ecosystems are very sensitive and one change
can completely alter the makeup of an ecosystem. Constructing houses in rural areas can result
in increases in sedimentation, erosion, salinity, and fertilizer pollution in
the local streams. Debris and litter
also start entering an ecosystem when is becomes urbanized. All of these things in large quantities can
be detrimental to amphibian populations and their development.
Salamanders are amazing in the fact that they are indicators for a
healthy ecosystem.
Salamanders have permeable skin that allows oxygen and other biological
components to enter and exit their bodies constantly. This is a perfect survival tool in wet
environments but it also makes them extra susceptible to being impacted by
pollutants and climate change. For this
reason, healthier streams usually have a higher diversity and number of
salamanders. Salamanders are very
important to a balanced ecosystem, because they keep the insect and arthropod
populations balanced.
Salamanders are a dominant keystone predator and it is very important
that we do everything in our power to protect them.
For my research I looked into water quality and its effects
on the number of salamanders within a stream.
From going out in the field, and the research I have conducted, it is
clear that salamander populations are impacted by the water quality in their
ecosystem. In all the exurban streams
there were huge amounts of litter all throughout the water and along the banks. From our data it is not clear how much
salinity, dissolved oxygen, conductivity, pH and water temperature affect
populations, but hopefully once more data is collected next semester there will
be a better indicate on of how populations are being impacted. Even though there are not conclusive results
from our data yet, other literature has made it clear that good water quality
is essential for a healthy salamander population. Next semester I would really like to look
into the amounts of litter in each stream and see if that has any effects on
salamander populations and diversity.
This creative inquiry has given me very valuable field
experience and helped me learn how to conduct research. In the world of Wildlife and Fisheries
Biology it is very important to not only have good academics but to also have a
lot of field experience. From personal
experience I can tell you that I have learned more through field work than I
have in my classes. You can learn about
techniques all day, but you will never fully understand them until you get the
hands on experience. Creative inquiries in general teach
you a hard work ethic and give you a chance to do something you are passionate
about.
I am excited to continue my work with salamanders and learn
even more from this CI. I am very
thankful to have found a CI that helped me discover my passion for salamanders
and their role they play in the natural world.
The wildlife in this world play a vital part in our survival. It is essential that we love and respect the
earth and all the plants and animals that abide there. Hopefully this Creative Inquiry and our
research can help us to communicate and educate the public, so that they can
help in the restoration and protection of salamanders.
