Ecology Lab

Spring 2010

At long last, students and I got out on the Ausable marsh in Clinton Cty to survey muskrat lodges. The ice was not really wanting to cooperate earlier in the semester. No injuries to report and a fun time to be had by all.

muskrat lodge w/ an entrance hole!

there are a lot of lodges at Ausable marsh, not as many over at Wickham about 3mi away.

pow wow at a large den.

Teddy spots one in the distance.

heading back in after the inventory...we just saw the osprey!

Neil Sullivan loving these lard worms!

Aaron Krinsky and Justin Farley making lard worms.

Sasha Dow-Kitson and Teddy Welch making worms of the same size.

Dana Rizer, Melinda Conroy, and Owen Keller arranging worms on their randomized feeding array.

Gorgeous lard worms! These worms are palatable, no quinine.

Dualing feeding arrays...da da duhhhh....

Class hard at work.

Fall 2008

This semester in Ecology lab, we have sampled and estimated populations of grasshoppers at Lake Alice Management Area, surveyed trees in Rugar woods along environmental gradients, sampled macroinvertebrates above and below stream impoundments, and foraged optimally for poker chips! Take a look at some of our experiences:

 Bonnie, Kizito, and Rosemarie optimally foraging.

Charlene and Kindsley are setting out their resources while Irving and Michelle  are waiting in their safe place.

Left to right: Matt, Melissa, Joe, Dan, and Chris getting ready for their feeding trial.

Katherine tossing a poker chip of high caloric intake over to Jessie, Matt, Pat, and Alex in their safe spot.

Mike is reaching for his resource with a socked and duck taped hand to simulate harsh weather and add complexity to his foraging bout.

Alex, Charlene, and Kat looking for a place to perform a kick net sampling of macroinvertebrates. They are at the above-dam site.

Melissa and Bonnie are looking at their kick net sample.

Macroinvertebrates, great bioindicators of stream health!

Kindsley and Mike happy to be outside collecting macroinvertebrates in the stream.

Emerson and Kindsley are sorting their macroinvertebrates from the Salmon River impoundment site.

Matt and Pat are looking attempting quantification of their mayfly larvae abundance.

Matt and Melissa are hard at work sorting algae from specimens.

Here is a closer look at what the students found below and above the dam on the Salmon River.

During the avian foraging lab, students observed birds feeding at varying distances from the woods, representative of increased predation risk the further one gets from the forest edge.

Amanda Groves is sitting patiently in her observation spot behind the blind awaiting the birds.

Now Amanda is counting seeds consumed and then refilling the feeder to the starting number of sunflower kernels.

Joe and Alex are placing their feeder in the 10m spot, furthest from forest cover. I bet they don't get many birds!

Our first feeding trial is over (Thurs PM), students Chris, Kat, and Amanda are setting up the experiment for the Friday morning feeding trial. Looks like birds feel comfortable feeding up to the 5m distance from the forest edge.
