Skin Deep: An Assessment of New Zealand Blue Whale Skin Condition

Creator:: Barlow, Dawn R., Pepper, Acacia L., and Torres, Leigh G.
Abstract:: Skin condition assessment of wildlife can provide insight into individual and population health. Yet, logistics can limit skin condition assessment of large whales. We developed a standardized, quantitative protocol using photographs to assess skin condition of blue whales in New Zealand, and demonstrate the value gained by testing hypotheses, documenting...

New species and new combinations in the genus Paraisaria (Hypocreales, Ophiocordycipitaceae) from the U.S.A., supported by polyphasic analysis

Creator:: Tehan, Richard M., Dooley, Connor B., Barge, Edward G., McPhail, Kerry L., and Spatafora, Joseph W.
Abstract:: Molecular phylogenetic and chemical analyses, and morphological characterization of collections of North American Paraisaria specimens support the description of two new species and two new combinations for known species. P. cascadensis sp. nov. is a pathogen of Cyphoderris (Orthoptera) from the Pacific Northwest USA and P. pseudoheteropoda sp. nov. is...

Microsatellite Markers for Red Drum, Sciaenops ocellatus

Creator:: Saillant, E., Cizdziel, K., O'Malley, Kathleen G., Turner, T. F., Pruett, C. L., and Gold, J. R.
Abstract:: Polymerase chain reaction (PCR) primers are reported for 68 nuclear-encoded microsatellites developed during the past several years from genomic libraries of red drum (Sciaenops ocelwtus). All68 microsatellites were tested for reproducibility and polymorphism on a sample of five to 12 red drum; 60 of the microsatellites were found to be...

Drone Up! Quantifying Whale Behavior From a New Perspective Improves Observational Capacity

Creator:: Torres, Leigh G., Nieukirk, Sharon L., Lemos, Leila, and Chandler, Todd E.
Abstract:: During traditional boat-based surveys of marine megafauna, behavioral observations are typically limited to records of animal surfacings obtained from a horizontal perspective. Achieving an aerial perspective has been restricted to brief helicopter or airplane based observations that are costly, noisy, and risky. The emergence of commercial small unmanned aerial systems...

Wild bee diversity is enhanced by experimental removal of timber harvest residue within intensively managed conifer forest

Creator:: Rivers, James W., Mathis, Codey L., Moldenke, Andrew R., and Betts, Matthew G.
Abstract:: The use of timber harvest residue as an energy source is thought to have environmental benefits relative to food-based crops, yet the ecological impact of this practice remains largely unknown. We assessed whether the abundance and diversity of wild bees (Apoidea) were influenced by the removal of harvest residue and...

Scaling up sustainability in commodity agriculture: Transferability of governance mechanisms across the coffee and cattle sectors in Brazil

Creator:: Hajjar, R., Newton, P., Adshead, D., Bogaerts, M., Maguire-Rajpaul, V. A., Pinto, L. F. G., McDermott, C. L., Milder, J. C., Wollenberg, E., and Agrawal, A.
Abstract:: A number of governance mechanisms address socio-environmental challenges associated with commodity agriculture in tropical forested countries. Governance mechanisms that prove effective in one agricultural sector are often applied to other sectors as well. For example, voluntary certification programs have been adopted by producers of commodities as diverse as beef, coffee,...

Impacts of the Northwest Forest Plan on forest composition and bird populations

Creator:: Phalan, Benjamin T., Northrup, Joseph M., Yang, Zhiqiang, Deal, Robert L., Rousseau, Josee S., Spies, Thomas A., and Betts, Matthew G.
Abstract:: The Northwest Forest Plan (NWFP) initiated one of the most sweeping changes to forest management in the world, affecting 10 million hectares of federal land. The NWFP is a science-based plan incorporating monitoring and adaptive management and provides a unique opportunity to evaluate the influence of policy. We used >25...

Ocean Acidification Has Multiple Modes of Action on Bivalve Larvae

Creator:: Waldbusser, George G., Hales, Burke, Langdon, Chris J., Haley, Brian A., Schrader, Paul, Brunner, Elizabeth L., Gray, Matthew W., Miller, Cale A., Gimenez, Iria, and Hutchinson, Greg
Abstract:: Ocean acidification (OA) is altering the chemistry of the world’s oceans at rates unparalleled in the past roughly 1 million years. Understanding the impacts of this rapid change in baseline carbonate chemistry on marine organisms needs a precise, mechanistic understanding of physiological responses to carbonate chemistry. Recent experimental work has...

Regionally consistent Western North America paleomagnetic directions from 15 to 35 ka: Assessing chronology and uncertainty with paleosecular variation (PSV) stratigraphy

Creator:: Reilly, Brendan T., Stoner, Joseph S., Hatfield, Robert G., Abbott, Mark B., Marchetti, David W., Larsen, Darren J., Finkenbinder, Matthew S., Hillman, Aubrey L., Kuehn, Stephen C., and Heil, Clifford W., Jr.
Abstract:: New Paleomagnetic Secular Variation (PSV) data from Fish Lake, Utah, USA, along with previously published regional records, allow us to build an independently dated Western North America PSV stack (WNAM17) from about 35 to 15 ka that quantifies dating and paleomagnetic uncertainties. In February 2014, we recovered a composite 11-m-long...
