Marine reserves are being established worldwide in response to a growing recognition of the conservation crisis that is building in the oceans. However, designation of reserves has been largely opportunistic, or protective measures have been implemented (often overlapping and sometimes in conflict) by different entities seeking to achieve different ends....
Flood flows, leaf breakdown, and plant-available nitrogen on a dryland river floodplain
Douglas C. Andersen, S. Mark Nelson, Dan Binkley
2003, Wetlands (23) 180-189
We tested the hypothesis that decomposition in flood-inundated patches of riparian tree leaf litter results in higher plant-available nitrogen in underlying, nutrient-poor alluvium. We used leafpacks (n = 56) containing cottonwood (Populus deltoides ssp. wislizenii) leaf litter to mimic natural accumulations of leaves in an experiment conducted on the Yampa...
Compensatory mechanisms in Great Lakes sea lamprey populations: implications for alternative control strategies
Michael L. Jones, R.A. Bergstedt, Michael B. Twohey, Michael F. Fodale, Douglas W. Cuddy, Jeffrey W. Slade
2003, Journal of Great Lakes Research (29) 113-129
Compensatory mechanisms are demographic processes that tend to increase population growth rates at lower population density. These processes will tend to reduce the effectiveness of actions that use controls on reproductive success to suppress sea lamprey (Petromyzon marinus), an economically important pest in the Great Lakes. Historical evidence for compensatory...
In situ determination of the annual thermal habitat use by lake trout (Salvelinus namaycush) in Lake Huron

2003, Journal of Great Lakes Research (29) 347-361
Records of the temperatures occupied by 33 lake trout (Salvelinus namaycush) at large in Lake Huron were obtained for up to 14 months per fish, at 75-minute intervals, from surgically implanted archival temperature tags. The dataset covered nearly three years, from October 1998 to June 2001, and included 160,000 observations....
The effects of bird use on nutrient removal in a constructed wastewater-treatment wetland
D.C. Andersen, J.J. Sartoris, J.S. Thullen, P.G. Reusch
2003, Wetlands (23) 423-435
A 9.9-ha constructed wetland designed to reduce nitrogen in municipal wastewater following conventional secondary treatment began operating in southern California's San Jacinto Valley in September 1994. The wetland incorporated zones of bulrush (Schoenoplectus acutus and S. californicus) for effluent treatment, plus areas of 1.8-m deep open water and other features...
Multiple pathways for woody plant establishment on floodplains at local to regional scales
D.J. Cooper, D.C. Andersen, Rodney A. Chimner
2003, Journal of Ecology (91) 182-196
1. The structure and functioning of riverine ecosystems is dependent upon regional setting and the interplay of hydrologic regime and geomorphologic processes. We used a retrospective analysis to study recruitment along broad, alluvial valley segments (parks) and canyon segments of the unregulated Yampa River and the regulated Green River in...

The bluestripe snapper, or taape, was introduced into Hawaii in the 1950s and has since become very abundant throughout the archipelago. As part of a health survey of reef fish in Hawaii, we necropsied 120 taape collected from various coastal areas south of Oahu and examined fish histology for extraintestinal...
Ecological criteria for evaluating candidate sites for marine reserves
Callum M. Roberts, Sandy Andelman, George Branch, Rodrigo H. Bustamante, Juan Carlos Castilla, Jenifer Dugan, Benjamin S. Halpern, Kevin D. Lafferty, Heather Leslie, Jane Lubchenco, Deborah McArdle, Hugh P. Possingham, Mary Ruckelshaus, Robert R. Warner
2003, Ecological Applications (13) 199-214
Several schemes have been developed to help select the locations of marine reserves. All of them combine social, economic, and biological criteria, and few offer any guidance as to how to prioritize among the criteria identified. This can imply that the relative weights given to different criteria are unimportant. Where...
Estimating lake-wide abundance of spawning-phase sea lampreys (Petromyzon marinus) in the Great Lakes: extrapolating from sampled streams using regression models
Katherine M. Mullett, John W. Heinrich, Jean V. Adams, Robert J. Young, Mary P. Henson, Rodney B. McDonald, Michael F. Fodale
2003, Journal of Great Lakes Research (29) 240-252
Lake-wide abundance of spawning-phase sea lampreys (Petromyzon marinus) can be used as one means to evaluate sea lamprey control efforts in the Great Lakes. Lake-wide abundance in each Great Lake was the sum of estimates for all streams thought to contribute substantial numbers of sea lampreys. A subset of these...
