Seasonal distribution and environmental associations among late larval and juvenile rockfish (Sebastes spp.) off Oregon and Washington: new insights based on genetics

Creator:: Johansson, Mattias L., Litz, Marisa N. C., Brodeur, Richard D., Britt, Tristan A., Vanegas, Camilo A., Hyde, John R., and Banks, Michael A.
Abstract:: Cytochrome B sequence data (FASTA format) from the paper “Seasonal distribution and environmental associations among late larval and juvenile rockfish (Sebastes spp.) off Oregon and Washington: new insights based on genetics”. The data was generated from a sample of 2534 unknown, field collected late-larval and juvenile rockfishes from the Pacific...

Contribution of subyearling estuarine migrant coho salmon (Oncorhynchus kisutch) to spawning populations on the southern Oregon coast

Creator:: Nordholm, Katherine E.
Abstract:: The typical coho salmon life history has been characterized by juvenile fish that spend their entire first year in freshwater habitats before migrating into estuaries as smolts. However, reports of early migrating coho fry (age 0), including migration downstream to estuarine habitats, date back to the 1960s. Until a few...

Juvenile coho salmon movement, growth and survival in a coastal basin of southern Oregon

Creator:: Weybright, Adam D.
Abstract:: Juvenile salmonids display highly variable spatial and temporal movement patterns that are influenced by density dependent (e.g., competition, predation) and density independent (e.g., genetics, stream discharge, physical habitat conditions) factors. The effects of these factors differ with fish life history stage, but will ultimately affect how salmonids utilize freshwater nursery...

Conservation and spatial use analyses for the recovery of bighorn sheep in the Peninsular Ranges

Creator:: Ostermann, Stacey D.
Abstract:: The status of wild sheep in North America typifies the plight of many wildlife species in modern times: wild sheep have declined to 10-40% of their numbers during pristine times and on a global scale approximately 31% of Caprine are considered threatened or critical. As human populations and the number...

Anthropogenic activities associated with the status of salmon stocks in Pacific Northwest watersheds

Creator:: Mrakovcich, Karina Lorenz
Abstract:: Stocks of salmon are declining in the Pacific Northwest. Based on region-wide studies that list and categorize the status of salmon stocks (Nehlsen et al., 1991; Huntington et al., 1994; and Nawa, 1995), I analyze the watersheds where stocks of salmon spawn for several anthropogenic variables, most of which are...

Comparison of methods to estimate population density of Pacific giant salamanders in small streams of the southern Oregon Cascades

Creator:: Leuthold, Niels C.
Abstract:: I compared hand sampling, two-pass multiple removal sampling, mark-recapture and catchability-based population estimates for the Pacific giant salamander (Dicamptodon tenebrosus) at 22 sites in 11 streams of Cascade Mountains of Oregon. Mark-recapture and catchability-based population estimates were not significantly different (p 0.86). Hand sampling and two-pass multiple removal population estimates...

Population Differentiation in two Northeastern Pacific Marine Species

Creator:: Curran, Lorne Sullivan
Abstract:: Population genetic techniques are now preeminent in differentiating wild populations. Natural resource managers rely on them in their efforts to restore viable populations of fish and wildlife. Overfishing adversely impacted Yelloweye Rockfish (Sebastes ruberrimus) on the U.S. West Coast in the late 20th century. Management actions included shutting down the...

Life-history organization of herring (Clupea harengus pallasi) in the northeast Pacific

Creator:: Aleaziz, Farzad
Abstract:: The distribution of herring (Clupea harengus pallasi) in the Northeast Pacific extends from southern California to northern Alaska. Studies on variation in herring life-history are limited to local characteristics and recruitment populations or relatively restricted regions of the Northeast Pacific. In this study I assessed herring life-history patterns and recruitment...

Enteromius pinnimaculatus (Cypriniformes: Cyprinidae), a new species from Southern Gabon

Creator:: Mipounga, Hans Kevin, Cutler, Joseph, Mve Beh, Jean Hervé, Adam, Benjamin, and Sidlauskas, Brian L.
Abstract:: With more than 407 species of freshwater and brackish water fishes, Gabon is a country rich in ichthyological biodiversity, but its aquatic environments remain poorly explored. We present and describe a new species of Enteromius, adding to the 16 species of Enteromius currently recorded from that country. This new species...

A review and key to the apogonid fishes (Pisces: Perciformes) of the Northwestern Arabian Sea and Southern Gulf of Oman, with description of two new species

Creator:: Mee, Jonathan K. L.
Abstract:: Field collections in the Southern Gulf of Oman and the Northwestern Arabian Sea, and examination of museum collections from this study area, yielded 7 genera and 33 species of apogonid fishes. Twenty one species of Apogon, one Archamia, four Cheilodipterus, three Fowleria, one Rhabdamia, two Siphamia, and one Holapogon are...
