Extinctions of North American Fishes During the past Century

  title={Extinctions of North American Fishes During the past Century},
  author={Robert R. Miller and James D. Williams and Jack E. Williams},
Abstract Extinctions of 3 genera, 27 species, and 13 subspecies of fishes from North America are documented during the past 100 years. Extinctions are recorded from all areas except northern Canada and Alaska. Regions suffering the greatest loss are the Great Lakes, Great Basin, Rio Grande, Valley of Mexico, and Parras Valley in Mexico. More than one factor contributed to the decline and extinction of 82% of the fishes. Physical habitat alteration was the most frequently cited causal factor (73…

Conservation status of imperiled north American freshwater and diadromous fishes
This list includes 700 extant taxa representing 133 genera and 36 families, a 92% increase over the 364 listed in 1989, and reflects the addition of distinct populations, previously non-imperiled fishes, and recently described or discovered taxa.
Conservation status of the North American fish fauna in fresh water
The status of the North American fish fauna includes 292 species of fishes in the categories of endangered, vulnerable, rare, indeterminate, and extinct. This constitutes 28% of the known fauna. The
Diversity, distribution, and conservation status of the native freshwater fishes of the Southern United States
The Southeastern Fishes Council Technical Advisory Committee reviewed the diversity, distribution, and status of all native freshwater and diadromous fishes across 51 major drainage units of the southern United States to determine the status of extinct, endangered, threatened, or vulnerable fishes.
Extinction Rates in North American Freshwater Fishes, 1900–2010
The present article investigates the issue with regard to North American freshwater fishes, finding the modern extinction rate is conservatively estimated to be 877 times greater than the background extinction rate for freshwater fishes.
Conservation of Native Pacific Trout Diversity in Western North America
This work focuses on Pacific trout in the genus Oncorhynchus, because they share a common evolutionary history, and many taxa in western North America have not been formally described, particularly in the southern extent of their ranges.
Distributional changes and population status of amphibians in the eastern Mojave Desert
The amphibian fauna of the study area has changed dramatically in the past century, primarily at lowland sites where habitat loss and modification have been extreme, and the distributions of 2 species characteristic of upland springs, red-spotted toad and Pacific chorus frog, appear to have changed little from their historical distributions.
Conservation Status of Freshwater Gastropods of Canada and the United States
Comparison of modern to background extinction rates reveals that gastropods have the highest modern extinction rate yet observed, 9,539 times greater than background rates.
Exotic fish assessments: An alternative view
Based on experience in Florida, this article questions some common assumptions involving exotic fishes and concludes that many have little, if any, scientific merit.
We summarized the status of fishes that have declined from one or more of the 14 major river drainages in South Dakota and of fishes that are restricted to only one river drainage in the state, even
Long‐term changes in the fish assemblage of the Laja River, Guanajuato, central Mexico
1. The structure and composition of fish communities in rivers of central Mexico have been altered as a result of water over-exploitation, habitat fragmentation, introduction of exotic species, and


Desert Fishes and Their Habitats
Abstract Recent habitat degradation within the desert areas of the southwestern United States and adjoining areas of Mexico has seriously depleted endemic fish populations. During the past 35 years,
Fishes of North America Endangered, Threatened, or of Special Concern: 1989
Comparison of the 1979 and 1989 list of rare North American fishes indicates that recovery efforts have been locally effective for some species, but are cleverer than was earlier believed.
Distributional patterns of Texas fresh-water fishes.
It is concluded that the basic factors controlling distribution patterns of fishes are climatic and geological, these determining the properties of the water.
Management of the Owens Pupfish, Cyprinodon radiosus, in Mono County, California
The Owens pupfish, Cyprinodon radiosus Miller, is restricted to Owens Valley along the eastern base of the Sierra Nevada Range of California and was thought to be extinct when it was described in 1948.
Status of the Deepwater Cisco Population of Lake Michigan
Abstract The species and size composition and the abundance of the cisco (Leucichthys spp.) population of Lake Michigan have undergone drastic changes since the sea lamprey became established in the
Extant Unless Proven Extinct? Or, Extinct Unless Proven Extant?
The proportion of the world's bird species for which extinct or endangered status is even suggested is trivial, and advocates of unrestrained economic growth proceed to dispute some of those 370 claims and suggest that the true proportion is even smaller.
Geographic Variation in Cyprinella lutrensis (Pisces: Cyprinidae) in the United States, with Notes on Cyprinella lepida

The Current State of Biological Diversity
Biological diversity must be treated more seriously as a global resource, to be indexed, used, and above all, preserved. Three circumstances conspire to give this matter an unprecedented urgency.
Virtual Extinction of Gambusia amistadensis n. sp., a Poeciliid Fish from Texas
The fishes of the family Anthiidae from the Western Indian Ocean and the Red Sea are studied to show the diversity of serraniform fishes found in this region.
