JP Nayers 1975 Journal IBP area, Barrow Alaska. 6 August (contd) When you approach + disturb them, they tend to move to the higher parts of the mounds. But they are feeding there part of the time anyway, pulling into the mats of moss. So how far any given pt., is it possible to read fairly on their behavior? Melanotus & most similarly humans, but almost never appear to forage up on the polygons undisturbed, so the problem is not as great. 7 August This a.m. at + the ground carried w/ snow. Snow flightmen. melted by 9:20 another day of micro. then an evening collecting melanotus, alpina + Arenaria near Footprint Lake. This is a disturbed area now rife with stands of Arctophila fulva and saturated ground. Earlier in the year it was a wet loaded field. The bar Well poligyn brachio cots throughout the lake (the reason for draining it), and because of the vehicular passage there are longships of exposed mud, in someplaces nice muddy puddles, e.g. There are many shorebirds here; in fact it and Volta Slough have about the densest concentration now in the tundra, with small groups of melanotus + alpina, fulicarius, Arenaria, some pusilla (even), Pluvialis, fossicollis. Actually Volta Slough is more uniformly densely & melanotus and Pluviculars. The trend for alpina to occur in lower areas, first entered in the journal 5 August, continues. Juvenile alpina are now found anywhere, particularly along peccoral puddles-grassland) small pools with much emergent vegetation. Yet one still sees alpina in the higher habitat as well. B+ The most apparent feature of their changing habitat usage is the number of alpina now along the liberal area. Where there is shallow water + mud, as the mouth of Volta (week or Barlow's ports), there are numbers of alpina. Shortly, if not already, the point will be reached where alpina are a thoroughly librorie species.
