fires, in the boreal forest? Answer 4. What are loopers, gentles, hellgrammites, rose slugs and doodle

Answers to Faunal Quiz
1. Rock flour is finely ground rock particles, chiefly silt size, resulting from glacial abrasion.
2. Frobisher Bay had its name changed on the first of January 1987 to Iqaluit, which means “place of many fish” in Inuktitut.
3. The mean fire rotation time in the boreal forest is about 60 years in drier pine-dominated stands, but 100 years in spruce forests, and up to hundreds of years in mixed-wood forests, but there is great variation on a range of scales.
4. Loopers, gentles, hellgrammites, rose slugs and doodle bugs are all insect larvae, respectively the immature stages of geometrid moths, blowflies, Dobson flies, sawflies and ant lions.
5. a) Marking is placing a signal on the host, typically done by an ovipositing female using pheromones, normally to limit superparasitism. b) Koinobionts permit hosts to continue to move, feed and defend themselves after parasitism. c) Idiobionts are parasitoids which kill or permanently paralyze their hosts during oviposition. d) Endoparasitoids are parasitoids that develop inside the host. e) Hyperparasitoids are are parasitoids that attack other parasitoids. f) Microtype eggs are tiny eggs deposited away from the host, for example on foliage, and then ingested by the host. |
