Long-term Colonization Of A Subarctic Artificial Reef System In Whittier, Alaska

Creator:: Levy, Charlotte S. and Brown, Eloise J.
Abstract:: Over half of the U.S. coastline is found in Alaska, and the majority of the state’s economic activity occurs along the coast. Increased coastal development poses a potential threat to nearshore habitats in Alaska. The installation of artificial reef (AR) systems can mitigate habitat loss; however, few AR systems have...

AFS Position Paper and Policy on Mining and Fossil Fuel Extraction

Creator:: Hughes, Robert M., Amezcua, Felipe, Chambers, David M., Daniel, Wesley M., Franks, James S., Franzin, William, MacDonald, Donald, Merriam, Eric, Neall, George, dos Santos Pompeu, Paulo, Reynolds, Lou, and Woody, Carol Ann
Abstract:: Following a four-year period of writing, member comment, and multiple revisions, the AFS Position Paper and Policy on Mining and Fossil Fuel Extraction was approved unanimously by the membership at the Society's annual business meeting August 19, 2015, in Portland, Oregon. The entire document can be read at fisheries.org/policy_statements; a...

Avian Predation on Juvenile Salmonids: Spatial and Temporal Analysis Based on Acoustic and Passive Integrated Transponder Tags

Creator:: Evans, Allen F., Payton, Quinn, Turecek, Aaron, Cramer, Bradley, Collis, Ken, Roby, Daniel D., Loschl, Peter J., Sullivan, Leah, Skalski, John, Weiland, Mark, and Dotson, Curtis
Abstract:: We evaluated the impact of predation on juvenile steelhead Oncorhynchus mykiss and yearling and subyearling Chinook Salmon O. tshawytscha by piscivorous waterbirds from 11 different breeding colonies in the Columbia River basin during 2012 and 2014. Fish were tagged with both acoustic tags and PIT tags and were tracked via...

Songbirds as sentinels of mercury in terrestrial habitats of eastern North America

Creator:: Jackson, Allyson K., Evers, David C., Adams, Evan M., Cristol, Daniel A., Eagles-Smith, Collin, Edmonds, Samuel T., Gray, Carrie E., Hoskins, Bart, Lane, Oksana P., Sauer, Amy, and Tear, Timothy
Abstract:: Mercury (Hg) is a globally distributed environmental contaminant with a variety of deleterious effects in fish, wildlife, and humans. Breeding songbirds may be useful sentinels for Hg across diverse habitats because they can be effectively sampled, have well-defined and small territories, and can integrate pollutant exposure over time and space....

Characterizing coal and mineral mines as a regional source of stress to stream fish assemblages

Creator:: Daniel, Wesley M., Infante, Dana M., Hughes, Robert M., Tsang, Yin-Phan, Esselman, Peter C., Wieferich, Daniel, Herreman, Kyle, Cooper, Arthur R., Wang, Lizhu, and Taylor, William W.
Abstract:: Mining impacts on stream systems have historically been studied over small spatial scales, yet investigations over large areas may be useful for characterizing mining as a regional source of stress to stream fishes. The associations between co-occurring stream fish assemblages and densities of various “classes” of mining occurring in the...

Is the diet of a typical shredder related to the physical habitat of headwater streams in the Brazilian Cerrado?

Creator:: Ferreira, Wander R., Ligeiro, Raphael, Macedo, Diego R., Hughes, Robert M., Kaufmann, Philip R., Oliveira, Leandro G., and Callisto, Marcos
Abstract:: Macroinvertebrates are important for processing leaf detritus in temperate streams, but studies about their role in tropical streams often present conflicting results. Via digestive tract analyses, we assessed the diets of Phylloicus sp. larvae (Trichoptera: Calamoceratidae), collected from streams of two southeastern Brazil river basins (Araguari, Sao Francisco). We classified...

Importance of environmental factors for the richness and distribution of benthic macroinvertebrates in tropical headwater streams

Creator:: Ferreira, Wander R., Ligeiro, Raphael, Macedo, Diego R., Hughes, Robert M., Kaufmann, Philip R., Oliveira, Leando G., and Callisto, Marcos
Abstract:: An understanding of the interactions among local environmental factors (e.g., physical habitat and water quality) and aquatic assemblages is essential to conserve biodiversity in tropical and subtropical headwater streams. We evaluated the relative importance of multiple physical and chemical habitat variables that influence the richness of Ephemeroptera, Plecoptera, and Trichoptera...

A global assessment of freshwater fish introductions in Mediterranean-climate regions

Creator:: Marr, Sean M., Olden, Julian D., Leprieur, Fabien, Arismendi, Ivan, Caleta, Marko, Morgan, David L., Nocita, Annamaria, Sanda, Radek, Tarkan, A. Serhan, and Garcia-Berthou, Emili
Abstract:: Mediterranean-climate regions (med-regions) are global hotspots of endemism 40 facing mounting environmental threats associated with human-related activities, including the ecological impacts associated with non-native species introductions. We review freshwater fish introductions across med-regions to evaluate the influences of non-native fishes on the biogeography of taxonomic and functional diversity. Our synthesis...

Can humans coexist with fishes?

Creator:: Albins, Mark A., Evans, Allison, Ismail, Gladys, Neilsen, Brian, Pusack, Timothy, Schemmel, Eva, Smith, Wade, Stoike, Susanne, Li, Hiram W., and Noakes, David L. G.
Abstract:: Deciding which textbook to assign to students is often a very difficult decision. A textbook should offer more than just a synthesis of information, it should inspire curiosity, cause one to reflect, and provide a framework for making decisions. Most reviews reflect a single opinion, sometimes based on personal preferences....

Comparing streambed light availability and canopy cover in streams with old-growth versus early-mature riparian forests in western Oregon

Creator:: Warren, Dana R., Keeton, William S., Bechtold, Heather A., and Rosi-Marshall, Emma J.
Abstract:: Light availability strongly influences stream primary production, water temperatures and resource availability at the base of stream food webs. In headwater streams, light is regulated primarily by the riparian forest, but few studies have evaluated the influence of riparian forest stand age and associated structural differences on light availability. In...
