The Power Of Physiology In Changing Landscapes: Considerations For The Continued Integration Of Conservation And Physiology, Christine L. Madliger, Oliver P. Love Oct 2015

The Power Of Physiology In Changing Landscapes: Considerations For The Continued Integration Of Conservation And Physiology, Christine L. Madliger, Oliver P. Love

Integrative Biology Publications

The growing field of conservation physiology applies a diversity of physiological traits (e.g., immunological, metabolic, endocrine, and nutritional traits) to understand and predict organismal, population, and ecosystem responses to environmental change and stressors. Although the discipline of conservation physiology is gaining momentum, there is still a pressing need to better translate knowledge from physiology into real-world tools. The goal of this symposium, "Physiology in Changing Landscapes: An Integrative Perspective for Conservation Biology", was to highlight that many current investigations in ecological, evolutionary, and comparative physiology are necessary for understanding the applicability of physiological measures for conservation goals, particularly in the …


Close Proximity Detection Interference With Acoustic Telemetry: The Importance Of Considering Tag Power Output In Low Ambient Noise Environments, Steven Thomas Kessel, Nigel Edward Hussey, Dale Mitchell Webber, Samuel Harvey Gruber, Joy Michelle Young, Malcolm John Smale, Aaron T. Fisk Mar 2015

Close Proximity Detection Interference With Acoustic Telemetry: The Importance Of Considering Tag Power Output In Low Ambient Noise Environments, Steven Thomas Kessel, Nigel Edward Hussey, Dale Mitchell Webber, Samuel Harvey Gruber, Joy Michelle Young, Malcolm John Smale, Aaron T. Fisk

Great Lakes Institute for Environmental Research Publications

When employing acoustic telemetry to study aquatic species, understanding the functional dynamics of the monitoring system is essential for effective study design, data interpretation, and analysis. Typically, researchers are concerned with maximum effective detection range and consequently tend to employ the largest most powerful tags the study species can carry without considerable energetic burden. In ideal acoustic conditions of low ambient noise environments, low attenuation, and reflective structure, higher powered tags can be detected at larger distances from the receiver, but they can also be subject to the phenomenon ‘Close Proximity Detection Interference’ (CPDI). This occurs when reflective barriers, such …


Chemical Cues And Pheromones In The Sea Lamprey (Petromyzon Marinus), Tyler J. Buchinger, Michael J. Siefkes, Barbara S. Zielinski, Cory O. Brant, Weiming Li Jan 2015

Chemical Cues And Pheromones In The Sea Lamprey (Petromyzon Marinus), Tyler J. Buchinger, Michael J. Siefkes, Barbara S. Zielinski, Cory O. Brant, Weiming Li

Biological Sciences Publications

Chemical cues and pheromones guide decisions in organisms throughout the animal kingdom. The neurobiology, function, and evolution of olfaction are particularly well described in insects, and resulting concepts have driven novel approaches to pest control. However, aside from several exceptions, the olfactory biology of vertebrates remains poorly understood. One exception is the sea lamprey (Petromyzon marinus), which relies heavily upon olfaction during reproduction. Here, we provide a broad review of the chemical cues and pheromones used by the sea lamprey during reproduction, including overviews of the sea lamprey olfactory system, chemical cues and pheromones, and potential applications to population management. …

Divergence Thresholds And Divergent Biodiversity Estimates: Can Metabarcoding Reliably Describe Zooplankton Communities?, Emily A. Brown, Frederic J.J. Chain, Teresa J. Crease, Hugh J. Macisaac, Melania E. Cristescu Jan 2015

Divergence Thresholds And Divergent Biodiversity Estimates: Can Metabarcoding Reliably Describe Zooplankton Communities?, Emily A. Brown, Frederic J.J. Chain, Teresa J. Crease, Hugh J. Macisaac, Melania E. Cristescu

Biological Sciences Publications

DNA metabarcoding is a promising method for describing communities and estimating biodiversity. This approach uses high-throughput sequencing of targeted markers to identify species in a complex sample. By convention, sequences are clustered at a predefined sequence divergence threshold (often 3%) into operational taxonomic units (OTUs) that serve as a proxy for species. However, variable levels of interspecific marker variation across taxonomic groups make clustering sequences from a phylogenetically diverse dataset into OTUs at a uniform threshold problematic. In this study, we use mock zooplankton communities to evaluate the accuracy of species richness estimates when following conventional protocols to cluster hypervariable …

Mid-Winter Temperatures, Not Spring Temperatures, Predict Breeding Phenology In The European Starling Sturnus Vulgaris, Tony D. Williams, Sophie Bourgeon, Allison Cornell, Laramie Ferguson, Melinda Fowler, Raime B. Fronstin, Oliver P. Love Jan 2015

Mid-Winter Temperatures, Not Spring Temperatures, Predict Breeding Phenology In The European Starling Sturnus Vulgaris, Tony D. Williams, Sophie Bourgeon, Allison Cornell, Laramie Ferguson, Melinda Fowler, Raime B. Fronstin, Oliver P. Love

Biological Sciences Publications

In many species, empirical data suggest that temperatures less than 1 month before breeding strongly influence laying date, consistent with predictions that short lag times between cue and response are more reliable, decreasing the chance of mismatch with prey. Here we show in European starlings (Sturnus vulgaris) that mid-winter temperature ca 50–90 days before laying (8 January–22 February) strongly (r2 = 0.89) predicts annual variation in laying date. Mid-winter temperature also correlated highly with relative clutch size: birds laid later, but laid larger clutches, in years when mid-winter temperatures were lower. Despite a high degree of breeding synchrony (mean laying …

Toward Accurate Molecular Identification Of Species In Complex Environmental Samples: Testing The Performance Of Sequence Filtering And Clustering Methods, Jullien M. Flynn, Emily A. Brown, Frederic J.J. Chain, Hugh J. Macisaac, Melania E. Cristescu Jan 2015

Toward Accurate Molecular Identification Of Species In Complex Environmental Samples: Testing The Performance Of Sequence Filtering And Clustering Methods, Jullien M. Flynn, Emily A. Brown, Frederic J.J. Chain, Hugh J. Macisaac, Melania E. Cristescu

Biological Sciences Publications

Metabarcoding has the potential to become a rapid, sensitive, and effective approach for identifying species in complex environmental samples. Accurate molecular identification of species depends on the ability to generate operational taxonomic units (OTUs) that correspond to biological species. Due to the sometimes enormous estimates of biodiversity using this method, there is a great need to test the efficacy of data analysis methods used to derive OTUs. Here, we evaluate the performance of various methods for clustering length variable 18S amplicons from complex samples into OTUs using a mock community and a natural community of zooplankton species. We compare analytic …
