Dr. Trevor Price Presents: What Determines the Gradient Bird Species Diversity Across the Himalayas?

Tuesday September 26th, 2017 at 4:00 PM in Biology Auditorium 136

WHAT DETERMINES THE GRADIENT IN BIRD SPECIES DIVERSITY ACROSS THE HIMALAYAS? Why are more species found in tropical than temperate regions? Explanations may be broadly divided into those rooted in history or in present day conditions. I describe our research on this issue, which uses birds of the Himalayas as a model system, and new […]

Wednesday October 11th, 2017 at 4:00 PM in Biology Auditorium 136

Dr. Chris Funk Presents: Playing god with guppies: testing the effects of gene flow on adaptation, fitness, and population dynamics using a model experimental system

Wednesday October 18th, 2017 at 4:00 PM in Biology Auditorium 136

The consequence of gene flow for local adaptation and fitness is a fundamental, yet unresolved, problem in evolutionary ecology and conservation biology. On the one hand, gene flow may introduce maladaptive alleles into a population, thereby reducing fitness. On the other hand, gene flow can add genetic variation to small, inbred populations, increasing fitness through […]

Dr. Patricia Schulte Presents: The Role of Mitochondria in Plasticity and Adaptation to Environmental Change

Tuesday October 24th, 2017 at 4:00 PM in Biology Auditorium 136

Animals are profoundly dependent on aerobic ATP generation by mitochondria, and thus the functional properties of this key cellular organelle play an important role in determining organismal performance and fitness in the context of a changing environment. In addition, because of the endosymbiotic origin of the mitochondrion, any adjustments to mitochondrial function necessarily involve tight […]

Dr. Alison Bell Presents: Tackling variation and plasticity in social behavior at the molecular level in sticklebacks

Tuesday September 12th, 2017 at 4:00 PM in Biology Auditorium 136

What does behavioral variation among individuals and behavioral plasticity look like at the molecular level? In this talk I will present two cases studies illustrating some of the complexities, nuances, and opportunities for studying variation and plasticity in behavior at the molecular level in threespined sticklebacks, a species famous for its behavioral repertoire and evolution. […]

Dr. Sonke Johnsen Presents: Hide and Seek in the Open Sea: Pelagic Camouflage and Visual Countermeasures

Tuesday September 5th, 2017 at 4:00 PM in Biology Auditorium 136

HIDE AND SEEK IN THE OPEN SEA: PELAGIC CAMOUFLAGE AND VISUAL COUNTERMEASURES Camouflage is exceptionally challenging in pelagic environments, due to their featureless nature. Thus, it is perhaps no surprise that pelagic species have evolved highly sophisticated cryptic strategies, three of which – transparency, mirrors, and counterillumination – are rare or absent in all other […]

Dr. Jeffrey Harvey Presents: Internet Blogs and Online Sources use Polar Bears and their Habitat as Keystone Dominoes for Denying Climate Change

Tuesday August 29th, 2017 at 4:00 PM in Biology Auditorium 136

Increasing surface temperatures, arctic sea ice loss, and other evidence of anthropogenic global warming (AGW) are acknowledged by every major scientific organization on Earth. However, there is a wide gap between the scientific consensus and public opinion. Internet blogs and online sources have strongly contributed to this consensus gap by fomenting misunderstandings of AGW causes and consequences. Polar bears (Ursus maritimus) have become a “poster species” for […]

Charlotte Alster Presents: PhD Seminar: Temperature Sensitivity as a Microbial Trait

Wednesday April 26th, 2017 at 4:00 PM in Yates 206

Reaction rates in biological systems are strongly controlled by temperature, yet the degree to which temperature sensitivity varies for different enzymes and microorganisms is being largely reformulated. The Arrhenius equation is the most commonly used model over the last century that predicts reaction rate response with temperature. However, the Arrhenius equation does not account for […]

Ryan Miller Presents: PhD Seminar: Interaction among biological and social drivers of policy at the wildlife-agricultural interface

Wednesday April 12th, 2017 at 4:00 PM in Yates 206

Policy to address human-wildlife conflict is often controversial and developing policy to mitigate these conflicts is increasingly important and often driven by both societal and biological factors.  Yet the interaction between societal and biological drivers and the relative contribution of these to environmental policy remains understudied. Understanding these interactions requires both investigation of the latent […]

Dr. Zachary Cheviron Presents: Evolutionary Systems Biology of Adaptation to Environmental Stress: Insights from High-Altitude Deer Mice

Tuesday April 4th, 2017 at 4:00 PM in Anatomy/Zoology Building W118

Both phenotypic plasticity and genotypic specialization can contribute to differences in physiological performance in species that are locally adapted to different environments. However, their relative contributions are expected to vary with respect to the spatial and temporal grain of environmental variation. In species that are distributed across steep elevational gradients, environmental conditions change dramatically over […]

Marc Schmidt Presents: Songs for sex: Shared neural circuits for song production and mate choice

Tuesday February 21st, 2017 at 4:00 PM in Anatomy/Zoology Building W118

Craig Pikaard Presents: Chromosomal and RNA-medieted mechanisms of selective gene silencing

Tuesday February 7th, 2017 at 4:00 PM in Anatomy/Zoology Building W118

Dr. Dennis Lavrov Presents: Evolution of the Mitochondrial Genome and Proteome in Non-Bilaterian Animals

Tuesday January 31st, 2017 at 4:00 PM in Anatomy/Zoology Building W118

The union of an archaeon and a proteobacterium at the origin of eukaryotic cell was a transformative event in the history of Earth that made evolution of complex life possible. Mitochondria are the most recognizable vestige of that event as they are semi-autonomous organelles with their own genome. Although the primary function of mitochondria – […]

Paul Hohenlohe Presents: Rapid evolution and a transmissible cancer in Tasmanian devils

Tuesday January 24th, 2017 at 4:00 PM in Anatomy/Zoology Building W118

Although cancer rarely acts as an infectious disease, a recently emerged transmissible cancer threatens the persistence of Tasmanian devils (Sarcophilus harrisii). Devil facial tumor disease (DFTD) has swept across nearly the entire species range, causing a population decline of 80 percent in just 20 years. Using high-throughput genomic sequencing approaches, we have detected evidence for rapid […]

Paul Brewer Presents: PhD Defense: Soil Heterogeneity in Agricultural and Natural Ecosystems

Monday December 19th, 2016 at 1:00 PM in Anatomy/Zoology Building W118

Stephen Pratt Presents: Decentralized mechanisms of collective behavior in social insects

Tuesday December 6th, 2016 at 4:00 PM in Anatomy/Zoology Building W118

Insect societies are the leading examples of collective cognition by social groups. Much like a single animal, a colony of ants can evaluate its surroundings, process information, and make decisions. Cognition emerges from a network of interacting ants, just as individual cognition emerges from interactions among neurons in the brain. The special appeal of these […]

Kristin Jenkins Presents: Modeling for Understanding: An authentic scientific experience in the undergraduate biology classroom

Wednesday November 2nd, 2016 at 4:00 PM in Yates 306

Models are an integral part of the scientific process used to represent ideas, solve problems, predict outcomes, and test theories.  Modeling involves a broad set of skills and approaches, including quantitative reasoning.  Students are exposed to models throughout their education, but may not understand the role of modeling in the scientific process or how to […]
