Diversity and distribution of anostomoid fishes (Teleostei: Characiformes) throughout the Guianas

Creator:: Sidlauskas, Brian L. and Vari, Richard P.
Abstract:: Diversité et distribution des poissons anostomoides (Teleostei, Characiformes) dans les Guyanes. Cinquante-six espèces, soit approximativement 20% des Characiformes de la superfamille des Anostomidea (familles des Anostomidae, Chilodontidae, Curimatidae et Prochilodontidae), fréquentent les eaux douces de la Guyane française, du Guyana et du Suriname bien que ces régions ne recouvrent qu’environ...

Arrhinolemur scalabrinii Ameghino, 1898, of the late Miocene - a taxonomic journey from the Mammalia to the Anostomidae (Ostariophysi: Characiformes)

Creator:: Bogan, Sergio, Sidlauskas, Brian, Vari, Richard P., and Agnolin, Federico
Abstract:: The fossil species Arrhinolemur scalabrinii, which was described from late Miocene deposits of Entre Ríos, Argentina, is reevaluated. Whereas the species was originally placed in the Primates (Mammalia) and later made the unique member of the order Arrhinolemuroidea within the Mammalia, our analysis indicates that the specimen is rather a...

New species of Cyphocharax (Ostariophysi: Characiformes: Curimatidae) from Suriname and French Guiana and a discussion of curimatid diversity on the Guiana Shield

Creator:: Vari, Richard P., Sidlauskas, Brian L., and Le Bail, Pierre-Yves
Abstract:: Cyphocharax biocellatus, a species of curimatid characiform apparently endemic to the Marowijne River/Fleuve Maroni system in Suriname and French Guiana, and the Maim River basin in French Guiana is described as new. The new species is diagnosed from congeners based on meristic and morphometric features and details of pigmentation of...

Genetic Connectivity of the Dungeness Crab (Cancer magister) Across Oceanographic Regimes

Creator:: Roegner, G. Curtis, Corbett, Kelly, Beacham, Terry D., Jacobson, Dave P., Jackson, Tyler M., and O'Malley, Kathleen G.
Abstract:: Limited approaches exist for studying population connectivity in widely dispersing marine benthic invertebrates. Genetic techniques can provide important insights toward identifying recruitment trajectories. Here, 10 microsatellite loci were used to examine connectivity among Oregon Dungeness crabs (Cancer magister, Dana, 1852) in the California Current System (CCS) (n = 801) as...

Translocating Adult Pacific Lamprey within the Columbia River Basin: State of the Science

Creator:: Ward, David L., Clemens, Benjamin J., Clugston, David, Jackson, Aaron D., Moser, Mary L., Peery, Chris, and Statler, David P.
Abstract:: The Pacific lamprey (Entosphenus tridentatus) is in decline in the Columbia River Basin, and translocating adult lamprey to bypass difficult migration corridors has been implemented since 2000. We describe and report results from two current translocation programs, provide context for use of translocation, and discuss potential benefits, risks, and uncertainties....

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....

Phylotastic! Making tree-of-life knowledge accessible, reusable and convenient

Creator:: Stoltzfus, Arlin, Lapp, Hilmar, Matasci, Naim, Deus, Helena, Sidlauskas, Brian, Zmasek, Christian M., Vaidya, Gaurav, Pontelli, Enrico, Cranston, Karen, Vos, Rutger, Webb, Campbell O, Harmon, Luke J., Pirrung, Megan, O'Meara, Brian, Pennell, Matthew W., Mirarab, Siavash, Rosenberg, Michael S., Balhoff, James P., Bik, Holly M., Heath, Tracy A., Midford, Peter E., Brown, Joseph W., McTavish, Emily Jane, Sukumaran, Jeet, Westneat, Mark, Alfaro, Michael E., Steele, Aaron, and Jordan, Greg
Abstract:: Background: Scientists rarely reuse expert knowledge of phylogeny, in spite of years of effort to assemble a great “Tree of Life” (ToL). A notable exception involves the use of Phylomatic, which provides tools to generate custom phylogenies from a large, pre-computed, expert phylogeny of plant taxa. This suggests great potential...

Competing tradeoffs between increasing marine mammal predation and fisheries harvest of Chinook salmon

Creator:: Chasco, Brandon E., Kaplan, Isaac C., Thomas, Austen C., Acevedo-Gutiérrez, Alejandro, Noren, Dawn P., Ford, Michael J., Hanson, M. Bradley, Scordino, Jonathan J., Jeffries, Steven J., Marshall, Kristin N., Shelton, Andrew O., Matkin, Craig, Burke, Brian J., and Ward, Eric J.
Abstract:: Many marine mammal predators, particularly pinnipeds, have increased in abundance in recent decades, generating new challenges for balancing human uses with recovery goals via ecosystem-based management. We used a spatio-temporal bioenergetics model of the Northeast Pacific Ocean to quantify how predation by three species of pinnipeds and killer whales (Orcinus...
