Tuesday August 30th, 2016 at 4:00 PM in Anatomy/Zoology Building W118

Anurans (frogs and toads) have a tympanic middle ear to transmit airborne sound from the environment to their inner ear sensory cells. Yet, many bufonid (true toad) species have independently evolved earlessness, the lack of a tympanic middle ear, despite the importance of acoustic communication in most toad mating systems. My thesis aims to determine […]

Dr. Mitchell McGlaughlin Presents: What does it mean to be a species? Conflicting evolutionary signals in the endemic Acmispon (Fabaceae) of the California Channel Islands

Tuesday February 9th, 2016 at 4:00 PM in Anatomy/Zoology Building W118

Despite the widespread usage of the term ‘species,’ considerable debate exists surrounding what criteria should be applied to recognize distinct evolutionary units. Most species have historically been recognized based on morphology, with modern species concepts recognizing that isolation among diverging taxa, whether it is reproductive, ecological, morphological, or genetic isolation, is a major driver of […]

Dr. Gail Patricelli Presents: Courtship negotiations in sage-grouse: experiments using robotic females

Tuesday January 26th, 2016 at 4:00 PM in Anatomy/Zoology Building W118

Males in many species must convince females to mate by producing elaborate courtship displays tuned to female preferences, like the song of a cricket or the train of a peacock. But courtship in many species is more like a negotiation than an advertisement, thus in addition to elaborate signals, success in courtship may require tactical […]

Dr. Alan Lemmon Presents: *BSPM Seminar* Anchored phylogenomics: rapidly expanding across the Tree of Life

Wednesday April 8th, 2015 at 12:00 noon in Plant Sciences Building E008

Hybrid enrichment is quickly becoming the preferred method of phylogenomic data collection, because it allows hundreds or thousands of nuclear loci to be obtained at a lower cost than other approaches. Anchored hybrid enrichment, by utilizing probes representing several diverse lineages within a target clade, is particularly powerful because it allows researchers to target loci […]

Dr. Emily Moriarty Lemmon Presents: Speciation via species interactions: exploring the indirect effects of reinforcement

Tuesday April 7th, 2015 at 4:00 PM in Anatomy/Zoology Building W118

Reproductive interactions among species represent a powerful evolutionary force driving diversification, particularly when organisms interact with a mosaic of other taxa across their geographic distribution. Theory predicts that spatial variation in community structure can lead to divergent selection on reproductive behaviors across geography, when different phenotypes are favored in different species assemblages. A critical outcome […]

The ability of organisms to survive seasonal or sporadic cycles of food deprivation and to efficiently store energy when nutrients are available has a selective advantage. Variation in these abilities or in the utilization of these abilities in modern societies, without such cycles, contributes to metabolic disease in humans. However, our knowledge concerning the molecular […]

Dr. Art Woods Presents: Destructive and constructive roles for physiological noise in organismal biology

Tuesday February 10th, 2015 at 4:00 PM in Anatomy/Zoology Building W118

In organisms, physiological noise arises from many sources—from changes in the external environment, from changes in internal physiological state, and from stochastic effects from the small numbers of particles interacting. I will discuss both destructive and constructive consequences of physiological noise, and I will propose a unified view for how organisms have evolved in response […]

Dr. Lauren Riters Presents: Birdsong and reward: neuroendocrine regulation of the motivation to communicate

Tuesday January 27th, 2015 at 4:00 PM in Anatomy/Zoology Building W118

Songbirds are well known for singing at high rates within multiple distinct social contexts. This suggests that they are highly motivated to communicate and raises the possibility that the consequences of vocal production are rewarding (or alternatively that reward can facilitate vocal production). Until recently, little was known about the neural regulation of the motivation […]

Kathy Cosenza Presents: **PhD Seminar** Effect of molting hormones (ecdysteroids) on myostatin and mTOR expression in skeletal muscle and limb regenerates in the blackback land crab, Gecarcinus lateralis

Wednesday January 21st, 2015 at 4:00 PM in Yates 206

  During premolt, increasing ecdysteroid levels cause claw muscle atrophy in Gecarcinus lateralis, allowing withdrawal of the claw at ecdysis. Myostatin (Gl-Mstn) is negatively correlated to ecdysteroids, while protein synthesis is up-regulated to allow myofibril remodeling during premolt. In mammals, glucocorticoids inhibit mechanistic Target of Rapamycin (mTOR)-dependent protein synthesis. Our hypothesis is that ecdysteroids inhibit […]

Tuesday October 15th, 2013 at 4:00 PM in Anatomy/Zoology Building W118

Plants, like all other organisms, need to assess and adapt to constant environmental changes throughout their life cycle. Defense responses to pathogens redirect cellular resources normally used in growth-related processes to the production of secondary metabolites, cell wall reinforcements and production of antimicrobial proteins. Immunity activation is therefore energetically costly, and requires complex mechanisms of […]

Ali Mehdawi – PhD Defense: Effects of Selenium Hyperaccumulation on Plant-Plant Interactions

Tuesday September 24th, 2013 at 9:00 AM in Yates 206

Hyperaccumulators accumulate toxic elements to extraordinary levels. Selenium hyperaccumulators can contain 0.1-1.5% of their dry weight in Se, levels toxic to most other organisms. Selenium promotes hyperaccumulator growth and offers the plant several ecological advantages through negative effects on Se-sensitive partners. High tissue Se levels reduce herbivory, and high-Se litter deposition can inhibit neighboring plants. […]

Dr. Mike Ryan Presents: What the frog’s brain tells the frog’s libido: sexual selection and communication in Tungara frogs

Tuesday March 26th, 2013 at 4:00 PM in Anatomy/Zoology Building W118

Sexual selection favors the evolution of traits that  enhance the attractiveness of males to females. Attractiveness depends on perception.  We have been studying various aspects of the neural and cognitive systems of frogs that bias what traits they find attractive, and thus drive the evolution of diversity under sexual selection.

Dr. Michael Lynch Presents: Mutation, drift, and the origin of subcellular features

Tuesday December 4th, 2012 at 4:00 PM in Anatomy/Zoology Building W118

Understanding the mechanisms of evolution and the degree to which phylogenetic generalities exist requires information on the rate at which mutations arise and their effects at the molecular and phenotypic levels. Although procuring such data has been technically challenging, high-throughput genomic sequencing is rapidly expanding our knowledge in this area. Most notably, information on spontaneous […]

Dr. Chris Lowe Presents: Molecules and morphology in reconstructing the origins of vertebrates: insights from weird body plans

Tuesday November 13th, 2012 at 4:00 PM in Anatomy/Zoology Building W118

The origins of the vertebrates have been a topic of debate for several centuries. Much of what we understand about the origins of our own complex body plan has been based on comparative morphological studies between the body plan of vertebrates and the simpler, basal chordate lineages. Amphioxus, one of these simple chordates, is broadly […]

Tuesday October 30th, 2012 at 4:00 PM in Anatomy/Zoology Building W118

Flooding stress, including soil waterlogging and partial to complete submergence, reduces oxygen availability for ATP production, triggering alterations in gene expression and energy metabolism.  The plant-specific Group VII Ethylene Response Factor (ERF) transcription factors have emerged as pivotal regulators of flooding and low oxygen responses. Several Arabidopsis thaliana Group VII ERF genes are low-oxygen and/or […]

Dr. Todd Palmer Presents: Mutualism in a community context: ants, plants and elephants in East Africa

Tuesday October 23rd, 2012 at 4:00 PM in Anatomy/Zoology Building W118

Throughout many East African savannas, the ant-plant Acacia drepanolobium is found in association with several species of symbiotic acacia ants. Although described as a classic example of protective mutualism, our recent investigations into the costs and benefits of this association have shown that ants are ineffective defenders against many types of herbivores, and impose demographic […]
