Competitive Exclusion Principle

AbstractThe newts Triturus vulgaris and T. cristatus are sympatric over almost the whole of their distributional areas, and they very often share the same breeding-ponds. According to "the competitive exclusion principle", however, no two species occupying the same ecological niche can persist together. Accordingly, within their habitat, the niches of the newts should be different. Studies on their macro- and microhabitat, diel activity, terrestrial seasonality and food, both of adults and larvae, indeed reveal such differences, especially in terrestrial seasonality, microhabitat and food preference. Although the habitat requirements of these newts are much the same, there is a clear resource partitioning between them, and adult T. cristatus also tends to exhibit a narrower niche breadth than does T.vulgaris.

Two Upper Triassic sphinctozoan sponges of the family Sebargasiidae were recovered from silicified residues collected in Hells Canyon, Oregon. These sponges areAmblysiphonellacf.A. steinmanni(Haas), known from the Tethys region, andColospongia whalenin. sp., an endemic species. The latter sponge was placed in the superfamily Porata by Seilacher (1962). The presence of well-preserved cribrate plates in this sponge, in addition to pores of the chamber walls, is a unique condition never before reported in any porate sphinctozoans. Aporate counterparts known primarily from the Triassic Alps have similar cribrate plates but lack the pores in the chamber walls. The sponges from Hells Canyon are associated with abundant bivalves and corals of marked Tethyan affinities and come from a displaced terrane known as the Wallowa Terrane. It was a tropical island arc, suspected to have paleogeographic relationships with Wrangellia; however, these sponges have not yet been found in any other Cordilleran terrane.
