SPOTTED SALAMANDER BIG NIGHT, 1 MARCH 2007 |
| |
The
students in BIOL 224, General Ecology, are conducting
a survey of the adult spotted salamanders (Ambystoma
maculatum) breeding in the small pond behind
the science building. The salamanders have been
breeding successfully in this pond for many years,
but the introduction of mosquitofish into the pond
four years ago raised concern that the population
may not be recruiting any new individuals.
This
class project is supervised by Biology Professor Linda
Fink and by visiting naturalist Mike Hayslett.
Ahead of the first warm spring rain, we installed
drift fences and had a practice drill. On 1
March, warm afternoon temperatures and rain starting
at dinner time provided perfect conditions, and the
class assembled in the lab at 6:30pm.
News
stories about this project appeared on the SBC
news site and in the Amherst
New Era Progress.

| In
late February we had a practice run. Without rain
and without salamanders, it was a breeze.
All photographs
of the salamander project were taken by Linda Fink and
by Suzanne Ramsey of SBC College Relations

ON 1 MARCH, IN
THE BEGINNING, OUR PLAN WORKED BEAUTIFULLY... |
|
| |

7:00pm
I went out to catch any early movers... Went clockwise
starting at line D. Found 2 at D, 1 at C, 1 at A, 0
at F and then we got to E....! Here we found almost
20 in E1, E2...and so on all the way up to E5. We radioed
in to inform everyone it was the big night. J.W. |

Everyone had a job. |

The
salamanders coming from lines C,D and A seemed larger
than the salamanders at E and F. J.W. |

What
I observed is that there were very few young, small
ones. The females are bigger than the males, they were
a lot fatter, because of the eggs. Some of them had
very big spots, while others had smaller ones. R.P.

As
more and more came into the lab, and there was a bigger
backup, I moved to working only with the intake of
the salamanders. It was a neat job because I was able
to see and document every salamander that was coming
into the lab. We assigned each salamander an individual
identification number, and we recorded the trap it
came from and the time...After we assigned each salamander
their identification number, we sent them off to a
processing group.... In 4 hours, I was able to handle
over 200 salamanders. ...The only thing that I wasn't
too happy about was that at one point in processing
I opened a bag full of salamanders, and a HUGE FURRY
SPIDER came crawling out of the bag and went up my
sleeve. That wasn't cool. L.M.

This
project was a great learning experience. It opened my
eyes to the importance of vernal pools and small ponds.
Without these habitats these spotted salamanders couldn't
exist. J.S.
|

I
did not think that spending 6:30pm to 1:00 am would
be fun while collecting salamanders, but I actually
had fun! I was very tired at the end, but it was a
good experience and I will never forget it. BC.
|

Well
this certainly was a life experience and I realize that
I love handling these critters. I thought they looked
like cartoon characters. ... I LOVE SALAMANDERS. S.D. |
|
|
| |

It was
really fun to get to work with other professors on such
an equal level. They were all a lot of fun to work with.
The class really stepped up and did a great job last
night. J.W. |

|

At one
time in the night the bags were covering half of the
lab table. It was really neat to go into the lab and
see everybody working so hard, together, and everyone
was very excited. C.C. |

AS THE POND TEEMED
WITH SALAMANDERS |
|
| |

I
stood at the top of the creek bed literally watching
some emerge from the soil for the first time, and
others who would quickly crawl across the leaf bed
until reaching the dam. The tall concrete dam, which
I later measured to be 80 cm high, would be the most
difficult part of the salamanders' migration to the
pond. Almost all salamanders would try to climb the
cement wall. Most would fail, but some were determined
and made it to a little ledge. The ledge was so wet
and had lots of overflowing water from the dam that
most would fall off the dam into the pit at the bottom
of the cement. N.P.
|

I
finally got to go back outside and see the action
at the pond as we released about 20 salamanders per
bucket. The bottom of the pond was entirely covered
in salamanders. And they WERE STILL COMING!
It is amazing what they will crawl through to get
to their pond. ... I knew I wanted to do field biology
and I wanted to work directly for the animal's benefit
but this was incredible. I can't wait to go out in
the field. S.R.

The
salamanders were much larger and more active than I
originally expected. I thought they would be rather
slow-moving, but the smaller individuals were pretty
quick. It also surprised me when they began making noise,
like little squeaking sounds. It was also interesting
to see how large the entire population was. Anywhere
a light shined on the immigration side of the fence
there would be at least one salamander moving through
the leaf litter. M.H. |

WHAT A NIGHT! |
|
| |

|
The
adventure last night also changed my opinion about fieldwork.
Before
this, I had always believed I would dislike intense,
hands-on work outdoors. But after last night, even in
such rough, rainy conditions, I really enjoyed mystelf.
Although I don't really see such intense field work
as a career, it is definitely something I would enjoy
taking part in again. It was nice to get away from textbooks
and actually see biology working and undergoing its
natural course. M.H.

At
7:45 I arrived at Line E, where I spent the next 3-1/2
hours. When I first got there, things were crazy...
We set to work trying to get ahead of the salamanders,
but as soon as we made it down the line, bagging the
salamanders, the pits had filled back up. It was easy
enough at first to label the bags, fill them with
leaves, and put the salamanders in them, but then
everything got wet. L.H.
|

All
I could think about all night was - this is what I want
to do! Inside the lab, everyone was so interested in
the study we were doing, that the energy in the lab
was overwhelming. N.P. |

I
really respect those people who stayed late who weren't
in the class. That shows true dedication to science!

TOTAL
= 551 SPOTTED SALAMANDERS
captured, sexed and measured or weighed!
This summer we will measure
recruitment by capturing new metamorph salamanders as
they leave the pond.
