Influence of a Benthic Predatory Fish (Cottus cognatus) on Invertebrate Community Structure and Secondary Production in a Tributary of the Susquehanna River
Autor: Neil H. Ringler, Charles R. Morgan
Publikováno v: Journal of Freshwater Ecology. 9:63-78
Populations of sculpin (Cottus cognatus) were altered to create stream sites with increased and decreased fish density. Subsequently, the response of benthic insect species was observed. Sculpin predation appeared to have little or no effect on size

Experimental Manipulation of Sculpin (Cottus cognatus) Populations in a Small Stream
Autor: Neil H. Ringler, Charles R. Morgan
Publikováno v: Journal of Freshwater Ecology. 7:227-232
We examined movement and age distribution of experimentally manipulated natural populations of slimy sculpin (Cottus cognatus) in streams having open and closed vegetation canopies. Densities were estimated in three treatments: reference populations

Orbital Evolution of the Kuiper Belt
Autor: Charles R. Morgan, A. J. R. Prentice
Publikováno v: Highlights of Astronomy. 13:922-922
The observed distribution of trans-Neptunian objects (TNOs) implies that they originally orbited in a narrow ring of radius 41 AU. The mass of the largest TNO was around 1 — 4 x 1026 g.

Histochemical demonstration of enzymatic heterogeneity within the mesocoxal and metacoxal muscles of Periplaneta americana
Autor: Charles R. Morgan, Marc S. Tarras, Darrell R. Stokes
Publikováno v: Journal of Insect Physiology. 26:481-486
Enzymatic activity in the mesocoxal and metacoxal muscles of the cockroach, Periplaneta americana , has been characterized using histochemical techniques. Our interpretation of the histochemical stains for myosin-ATPase (pre-incubated at pH 9.4, 10.4

Biochemical Adaptations in Insect Muscle
Autor: Charles R. Morgan, Darrell R. Stokes
Publikováno v: Locomotion and Energetics in Arthropods ISBN: 9781468440669
The insects are among the most successful groups of organisms known. Nearly one million species have been described, with perhaps an equal number remaining to be discovered; only the less conspicuous nematodes are more abundant. Numbers of species im
