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 […]

Comparative genomics from mitochondria, plastids, and mutualistic endosymbiotic bacteria has shown that the stable establishment of a bacterium in a host cell results in genome reduction. Although many highly reduced genomes from endosymbiotic bacteria are stable in gene content and genome structure, organelle genomes are sometimes characterized by dramatic structural diversity. Previous results from Hodgkinia, […]

  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 […]

Among vertebrates, most of the largest genomes are found within the salamanders, a clade of amphibians that includes 600+ recognized species. Salamander genome sizes range from ~14 Gb to ~120 Gb; these values are larger than all bird, mammal, reptile, and frog genomes, as well as most fish genomes. My lab is working to understand […]

POSTPONED UNTIL FALL 2013 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 […]

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.

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 […]

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 […]

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 […]

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 […]

Animals use their sensory systems to navigate their environment and to mediate interactions with other animals.  Traits that mediate interactions between predator and prey rely on fast, specialized sensory inputs.  Ion channels expressed in excitable membranes are critical for encoding information about and producing responses to sensory stimuli.  Given the critical role of ion channels […]

More than five years ago a group of us published papers in Nature and American Naturalist that proposed partially restoring the lost North American Pleistocene megafauna with conspecifics and closely related proxies for tortoises, cheetah, elephants, and other species. In this seminar I will summarize our initiative and the subsequent response from conservation biologists and […]

Extending ecological research back through deep time provides an important framework for understanding the macroevolutionary context of the structure, function, and dynamics of today’s and tomorrow’s ecosystems.  While many paleoecological studies focus on species morphology, diversity, and distributions, there are also opportunities to analyze complex species interactions.  We have compiled detailed food webs for ancient […]

The era of genome engineering has arrived. Synthetic DNA technologies can now generate sufficient DNA to construct tens of thousands of genes in parallel; enough to synthesize several complete microbial genomes at the same time. Genome sequencing has advanced to the point where so synthesized artificial genomes could be completely sequenced in < 1 day […]

We respond to the actions of others by making decisions and executing them. The research of Dr. Hofmann aims to elucidate the kinds of decisions that prove to be most consequential in our lives: social status, mate selection and escaping from danger. Using African cichlid fishes – famous for their amazing diversity, social complexity and […]

The Global Ocean Sampling project was initiated in the fall of 2003.  Since then, samples have been collected from over 500 locations in most of Earth’s major oceans and seas.  In parallel, the number of completed microbial genomes numbers in the 1000’s, thus it was sobering to find that only approximately a quarter of the […]
