Physiological alterations following severe hypoxic stress in two species of fresh-water fish

Creator:: Heath, Alan G.
Abstract:: Bluegill sunfish, Lepomia macrochirus, and cutthroat trout, Salmo clarki, were exposed to a rapidly declining oxygen tension for a period of time sufficient to just cause loss of equilibrium in the fish. During recovery from the stress, measurements of oxygen uptake, blood lactic acid, blood glucose, liver glycogen, muscle glycogen,...

Role of priority effects and habitat complexity in coral-reef fish communities

Creator:: Almany, Glenn R.
Abstract:: Understanding the processes that influence the composition of animal communities is a central goal in ecology. Interactions between established residents and colonizing juveniles that affect the subsequent survival of juveniles may influence community composition. In a series of experiments on coral reef fish communities in the Bahamas and Australia, I...

Factors affecting the dynamics and regulation of coral-reef fish populations

Creator:: Webster, Michael Scott
Abstract:: Ecologists have long questioned why fluctuating populations tend to persist rather than go extinct. Populations that persist indefinitely are regulated by mechanisms that cause demographic density dependence, which works to bound fluctuation above zero. In a series of studies, I have sought to determine the processes and mechanisms that regulate...

Effects of the invasive Pacific red lionfish Pterois volitans on native Atlantic coral-reef fish communities

Creator:: Albins, Mark A.
Abstract:: Predatory lionfishes (Pterois volitans and P. miles) were introduced to Florida waters during the mid to late 1980s, and eventually established self-sustaining breeding populations in the tropical western Atlantic. These invasive species are now widespread along the southeastern seaboard of the United States, across the Caribbean Sea, and in the...

Selection on larval and adult body size in a marine fish: potential evolutionary responses and effects on population dynamics

Creator:: Johnson, Darren W.
Abstract:: Many species have complex life cycles in which a dispersive larval stage is followed by a relatively sedentary adult stage. For such species, reproductive output is often high and large variation in survivorship throughout early life-history phases (eggs and larvae) can lead to dramatic fluctuations in recruitment which may in...

Population dynamics of coral-reef fishes : spatial variation in emigration, mortality, and predation

Creator:: Overholtzer-McLeod, Karen L.
Abstract:: Understanding the dynamics of open marine populations is difficult. Ecological processes may vary with the spatial structure of the habitat, and this variation may subsequently affect demographic rates. In a series of observational and experimental studies in the Bahamas, I examined the roles of emigration, mortality, and predation in the...

A biological and taxonomic study of selected myxosporida of some Oregon fresh-water fishes

Creator:: Wyatt, Ellis Junior
Abstract:: Biological studies were conducted on a histozoic myxosporidan Myxobolus insidiosus (Wyatt and Pratt, 1963) from the musculature of Oncorhynchus tshawytscha (Walbaum). This organism is known to occur in spring chinook salmon in Oregon and coho salmon O. kisutch (Walbaum) in Washington. In addition Myxobolus kisutchi (Yasutake and Wood, 1957) was...
