Ecology labs and autumn colours

I have been incredibly busy this school semester demonstrating labs for the ecology course, grading lab reports, as well as preparing for my PhD comprehensive examination.  I tried to take some pictures whenever I am outside, otherwise I am indoors working away.

The ecology course consists of two field labs - first on the effects of abiotic factors in the stream on benthic macroinvertebrate biodiversity and second on tree diversity in different successional stages - both of which take place at Gatineau Park.

Last month (September 12th), the teaching assistants and lab demonstrator went out to familiarize ourselves with the study area.

Recap of the week - new macro technique and critters saw during Enrichment camp

While experimenting with my Nikon P&S lately, I found out that if I hold my small hand lens (for plant identification) in front of the P&S lens, then I can get a pretty decent close-up photo of the critter/flower (but I need to get very close).

I took photos of this spider just outside my office window on Monday.

On Tuesday and Thursday, I assisted with two of the mini-course programs held here at Trent.  One was getting elementary students "Wild About Nature!", and the second was teaching students about "Habitat and Organisms".  It has been a while since I worked with children, but it's quite rewarding especially now that I am teaching them about nature.

For "Wild About Nature!", we first made a field kit, consisting of a clinometer, a plant press, and an insect-collecting container.  We then took the children outside to measure tree heights using the clinometer.  We also played games with the children - one called "Predator & Prey" (three trophic levels - grasshoppers, orioles, and hawks) and one with three different feeding apparatuses (modified plastic knifes, spoons, and forks) to collect different prey types.  We also took the children outside to collect plants and insects.
