Read the following paragraph:

Pathogens have important effects on host growth, behavior, and population dynamics. Nevertheless, the impact of parasitic infection on host populations may be strongly context dependent. For example, the outcome of host–pathogen interactions may be subject to change based on the level of abiotic stress experienced by the host. In northeastern Connecticut, USA, larvae of the gray treefrog (Hyla versicolor) co-occur in temporary and permanent ponds with a snail (Pseudosuccinea columella) that is frequently infected with a digenetic trematode (Telorchis sp.) whose free-swimming cercariae subsequently infect H. versicolor tadpoles. Field collections of H. versicolor tadpoles suggest that the prevalence of infection by trematodes can be as high as 71%. We measured survival, mass, and time to metamorphosis of larval gray treefrogs in an artificial pond experiment designed to determine how infection with trematode cercariae and the stress of pond drying interact to influence gray treefrog performance. (from Kiesecker and Skelly 2001)

            In your own words, what is this author saying?

We exposed gray treefrog tadpoles to infected snails, uninfected snails, or no snails, within artificial ponds that were either permanent or subjected to a 49-d drying regime.

            Based on this sentence, what is the minimum number of artificial ponds needed?

Draw a graph that shows the size of a deer population increasing over time.

Sketch and label a map of our classroom.

Name as many local plants as you can (if you know more than 10, ok to list just 10).

If you recognize any of the following organisms, write the name below the picture.

(pictures will be of white-tailed deer, mule deer, bluebonnet (not flowering), bluebonnet (flowering), nandina, hackberry (close-up of a branch), cougar, bobcat)

What does a cougar eat?
