Target loads of atmospheric sulfur and nitrogen deposition for protection of acid sensitive aquatic resources in the Adirondack Mountains, New York

Creator:: Sullivan, T. J., Cosby, B. J., Driscoll, C. T., McDonnell, T. C., Herlihy, A. T., and Burns, D. A.
Abstract:: The dynamic watershed acid-base chemistry model of acidification of groundwater in catchments (MAGIC) was used to calculate target loads (TLs) of atmospheric sulfur and nitrogen deposition expected to be protective of aquatic health in lakes in the Adirondack ecoregion of New York. The TLs were calculated for two future dates...

An a priori process for selecting candidate reference lakes for a national survey

Creator:: Herlihy, Alan T., Sobota, Janel Banks, McDonnell, Todd C., Sullivan, Timothy J., Lehmann, Sarah, and Tarquinio, Ellen
Abstract:: One of the biggest challenges when conducting a national-scale assessment of lakes, such as the 2007 US National Lake Assessment (NLA), is finding enough reference lakes to set appropriate expectations for the assessed sites. In the NLA, a random design was used to select lakes for sampling to make unbiased...

Colonization and extinction in dynamic habitats: an occupancy approach for a Great Plains stream fish assemblage

Creator:: Falke, Jeffrey A., Bailey, Larissa L., Fausch, Kurt D., and Bestgen, Kevin R.
Abstract:: Despite the importance of habitat in determining species distribution and persistence, habitat dynamics are rarely modeled in studies of metapopulations. We used an integrated habitat-occupancy model to simultaneously quantify habitat change, site fidelity, and local colonization and extinction rates for larvae of a suite of Great Plains stream fishes in...

Eastern mosquitofish resists invasion by nonindigenous poeciliids through agonistic behaviors

Creator:: Thompson, Kevin A., Hill, Jeffrey E., and Nico, Leo G.
Abstract:: Florida is a hotspot for nonindigenous fishes with over 30 species established, although few of these are small-bodied species. One hypothesis for this pattern is that biotic resistance of native species is reducing the success of small-bodied, introduced fishes. The eastern mosquitofish Gambusia holbrooki is common in many freshwater habitats...

Patterns of loggerhead turtle ontogenetic shifts revealed through isotopic analysis of annual skeletal growth increments

Creator:: Ramirez, Matthew D., Avens, Larisa, Seminoff, Jeffrey A., Goshe, Lisa R., and Heppell, Selina S.
Abstract:: Ontogenetic changes in resource use often delimit transitions between life stages. Ecological and individual factors can cause variation in the timing and consistency of these transitions, ultimately affecting community and population dynamics through changes in growth and survival. Therefore, it is important to document and understand behavioral and life history...

Ecological effects of nitrogen and sulfur air pollution in the US: what do we know?

Creator:: Greaver, Tara L., Sullivan, Timothy J., Herrick, Jeffrey D., Barber, Mary C., Baron, Jill S., Cosby, Bernard J., Deerhake, Marion E., Dennis, Robin L., Dubois, Jean-Jacques B., Goodale, Christine L., Herlihy, Alan T., Lawrence, Gregory B., Liu, Lingli, Lynch, Jason A., and Novak, Kristopher J.
Abstract:: Four decades after the passage of the US Clean Air Act, air-quality standards are set to protect ecosystems from damage caused by gas-phase nitrogen (N) and sulfur (S) compounds, but not from the deposition of these air pollutants to land and water. Here, we synthesize recent scientific literature on the...

Modelling dendritic ecological networks in space: an integrated network perspective

Creator:: Peterson, Erin E., Ver Hoef, Jay M., Isaak, Dan J., Falke, Jeffrey A., Fortin, Marie-Jos ee, Jordan, Chris E., McNyset, Kristina, Monestiez, Pascal, Ruesch, Aaron S., Sengupta, Aritra, Som, Nicholas, Steel, E. Ashley, Theobald, David M., Torgersen, Christian E., and Wenger, Seth J.
Abstract:: Dendritic ecological networks (DENs) are a unique form of ecological networks that exhibit a dendritic network topology (e.g. stream and cave networks or plant architecture). DENs have a dual spatial representation; as points within the network and as points in geographical space. Consequently, some analytical methods used to quantify relationships...

Final report : environmental stresses and skeletal deformities in fish from the Willamette River, Oregon, USA

Creator:: Villeneuve, Daniel L., Curtis, Lawrence R., Jenkins, Jeffrey J., Warner, Kara E., Tilton, Fred A., Kent, Michael L., Watral, Virginia G., Cunningham, Michael E., Markle, Douglas F., Sethajintanin, Doolalai, Krissanakriangkrai, Oraphin, Johnson, Eugene R., Grove, Robert Allan, Anderson, Kim A., Oregon State University.

Department of Fisheries and Wildlife, and Institute for Natural Resources
Abstract:: The Willamette River, one of only 14 American Heritage Rivers, flows through the most densely populated and agriculturally productive region of Oregon. Previous biological monitoring of Willamette River fish detected elevated frequencies of skeletal deformities in fish from certain areas of the lower (NP [NP], rivermile [RM] 26-55) and middle...

A Stable Isotope Tracer Study of the Influences of Adjacent Land Use and Riparian Condition on Fates of Nitrate in Streams

Creator:: Sobota, Daniel J., Johnson, Sherri L., Gregory, Stan V., and Ashkenas, Linda R.
Abstract:: The influence of land use on potential fates of nitrate (NO3-) in stream ecosystems, ranging from denitrification to storage in organic matter, has not been documented extensively. Here, we describe the Pacific Northwest component of Lotic Intersite Nitrogen eXperiment, phase II (LINX II) to examine how land-use setting influences fates...

The Effects of Forest Fuel-Reduction Treatments in the United States

Creator:: Stephens, Scott L., McIver, James D., Boerner, Ralph E. J., Fettig, Christopher J., Fontaine, Joseph B., Hartsough, Bruce R., Kennedy, Patricia L., and Schwilk, Dylan W.
Abstract:: The current conditions of many seasonally dry forests in the western and southern United States, especially those that once experienced low- to moderate-intensity fire regimes, leave them uncharacteristically susceptible to high-severity wildfire. Both prescribed fire and its mechanical surrogates are generally successful in meeting short-term fuel-reduction objectives such that treated...
