Zoogeographical Implications By WILLIAM R. HEARD,~ RICHARD L. WALLACE, 2 and WILBUR L. HARTMAN~ ABSTRACT Katmai National Monument covers 10,916 km.2 on the base of the Alaska Penin­ sula and is divided by the Aleutian Mountain Range into two principal drainage areas. Streams north of the Aleutian Range flow into Bristol Bay of the Bering Sea, and those south of the mountains flow into Shelikof Strait of the North Pacific Ocean. The large multilake Naknek River system is the dominant drainage area on the Bristol Bay side of the monument, whereas small single lakes and short streams and rivers constitute many separate drainages on the Shelikof Strait side. Twenty­ four species of fish occur in the Bristol Bay drainages of the monument, but only eight species were collected in streams and lakes draining into Shelikof Strait. Evi­ dently the Aleutian Range has been a barrier to the southward movement of fresh­ water fishes in the monument. All eight species in Shelikof Strait drainages are capable of dispersal through salt water, whereas several forms in Bristol Bay drainages require fresh water for dispersal. Variable numbers of species occur in the interconnecting lakes of the Naknek River system. Naknek Lake, the downstream terminus of the lake system, contains 24 known species and each upstream lake contains fewer species than the one into which it drains. The present distribution of fishes in this system is discussed in terms of the sequential timing of species invasion and the postglacial development of barriers. INTRODUCTION Katmai National Monument is at the base of aula. The area has a long history ofvolcanism the Alaska Peninsula in southwestern Alaska (Wahrhaftig, 1965), and glaciation was exten­ (fig. 1). It was established by Presidential sive during the Pleistocene (Muller, 1952; Proclamation in 1918, primarily to preserve Karlstrom, 1957). Several streams on each the spectacular features of the Valley of Ten slope of the Aleutian Range still originate Thousand Smokes--a volcanic phenomenon that from small, vestigial glaciers. One of the most resulted in 1912 from the eruption of the vol­ important features influencing
