Preface: Proceedings of the seventh international symposium on the biology and management of corigonid fishes Preface: Proceedings of the seventh international symposium on the biology and management of corigonid fishes
This volume is the proceedings of the Seventh International Symposium on the Biology and Management of Coregonid Fishes (ISBMCF). As in all six preceding symposia, the seventh meeting of the ISBMCF provided an international forum for the scientific review and discussion of the various taxonomic, biological, ecological, and management issues that surround this important group of Holarctic...

Preliminary evaluation of the coalbed methane potential of the Gulf Coastal Plain, USA and Mexico Preliminary evaluation of the coalbed methane potential of the Gulf Coastal Plain, USA and Mexico
Several areas in the Gulf Coast have potential for coalbed gas accumulations. These areas include parts of southern Alabama and Mississippi, north-central Louisiana, northeast, east-central and south Texas and northeastern Mexico. The coal deposits in these areas vary in rank, thickness, lateral extent and gas content, and range in age from Late Cretaceous to Eocene. Gas desorption tests...

Random effects and shrinkage estimation in capture-recapture models Random effects and shrinkage estimation in capture-recapture models
We discuss the analysis of random effects in capture-recapture models, and outline Bayesian and frequentists approaches to their analysis. Under a normal model, random effects estimators derived from Bayesian or frequentist considerations have a common form as shrinkage estimators. We discuss some of the difficulties of analysing random effects using traditional methods, and argue that a

Reconstruction of Anacostia wetlands: success? Reconstruction of Anacostia wetlands: success?
Historically, the tidal Anacostia River in Washington, D.C. had been an extensive system of freshwater tidal marshes replete with a full array of wetland vegetation dominated by wild rice. The local Nacochtank Indians had found the abundant fish and wildlife sufficient to sustain their daily lives. White man's intrusion upon the landscape gradually brought about deterioration of the...

Sources, fate, and effects of PAHs in shallow water environments: a review with special reference to small watercraft Sources, fate, and effects of PAHs in shallow water environments: a review with special reference to small watercraft
Polycyclic aromatic hydrocarbons (PAHs) are aromatic hydrocarbons with two to seven fused carbon (benzene) rings that can have substituted groups attached. Shallow coastal, estuarine, lake, and river environments receive PAHs from treated wastewater, stormwater runoff, petroleum spills and natural seeps, recreational and commercial boats, natural fires, volcanoes, and atmospheric...
