AbstractSiricids and their parasitoids were reared from Scots pine (Pinus sylvestris L. (Pinaceae)) trees infested by Sirex noctilio F. in central New York State. Sirex noctilio accounted for 94.3% of the siricid specimens emerging, totaling 1313 specimens from six trees, with a maximum of 495 from one tree. Of the individuals emerging per tree, 20.6 ± 5.2% were female. Two native siricids, Sirex nigricornis F. and S. edwardsii Brullè, also emerged from trees but in low numbers. Three hymenopteran parasitoid species that attack siricids emerged, totaling 21.8 ± 6.4% parasitism per tree. Ibalia leucospoides ensiger Norton (Ibaliidae) was by far the most abundant parasitoid, at 20.5 ± 6.3% parasitism per tree. The percentage of female S. noctilio emerging was positively correlated with wood diameter, whereas percent parasitism by I. l. ensiger was negatively correlated with wood diameter.

Lake Site

A trench excavated into the waterlogged fringe of the Lamoka Lake site in central New York state yielded cultural stratigraphic zones with abundant artifacts and food remains. A peaty layer resting upon Late Archaic beach or streamside deposits produced late Middle Woodland (Kipp Island phase) ceramics and stone implements. Discoveries of wood, fruit pits, and nuts in the same layer as well as rich congeries of animal bones indicate that the archaeological potential of the Lamoka Lake site is not exhausted.

Penguin Species

This chapter narrates the author's first island-hopping trip to Bleaker Island, wherein she hoped to see at least two penguin species, the steamer duck, and maybe a black-necked swan. There are no trees on Bleaker — which is true throughout most of the Falklands — and a large rocky hill covers about half of the small island. Because the author hails from the land of trees in central New York State, the sheer openness of the landscape felt raw and exposed. The author then describes the skuas. These are huge, predatory birds that look like ubergulls. They are the bird bullies of the islands — harassing other birds to drop their food, attacking and devouring young birds, and swooping and diving on anything they do not like, including people.

James Fenimore Cooper was reared in Cooperstown, a central New York State community founded by his father after a large land purchase in what was then the frontier. The area is now categorized as part of Northern Appalachia. Cooper is best known for the five novels in his “Leatherstocking Tales” series, which explore life on the American frontier....
