Projects: Foraging and navigation using biogeochemical regulators of climate change, Bird Olfaction, Phenotypic plasticity and conservation
My specialty is olfaction - the sense of smell - and much of my research has focused on exploring how marine birds and fishes use smell in the natural environment. I have worked in areas ranging from olfactory homing in salmon, to olfactory foraging, navigation and individual recognition in birds, and in particular, petrels and albatrosses. Because our world is experiencing rapid, anthropogenic change, our work increasingly interfaces with problems associated with global climate, habitat loss or degradation and by-catch concerns in marine fisheries. Many of the species we study are currently threatened or endangered. In line with this concern, we also conduct research on the proximate and evolutionary factors contributing to phenotypic plasticity, and this work has been carried out primarily with model fish species (various species of desert pupfish and salmon).
Current and ongoing projects: 1). Foraging and navigation using biogeochemical regulators of climate change. How do marine birds and fishes forage and navigate over the seemingly featureless landscape of the open ocean? My lab has pioneered research showing that biogeochemical regulators of climate also serve as signal molecules in marine habitat. Instead of a featureless landscape, I have suggested that seabirds use changes in the olfactory landscape to recognize potentially productive foraging opportunities as they fly over them (Nevitt et al., 1995, Nature). This odor landscape reflects bathymetric features, which tend to accumulate phytoplankton and therefore prey, and we speculate that birds build up a map of these features over time (Nevitt, 2000). I proposed this theory when I discovered that dimethyl sulfide (DMS), and its precursor dimethylsulfoniopropionate (DMSP), can be detected by wide-ranging procellariiform seabirds (Nevitt et al. 1995). This work has been extended by our lab and others to include harbor seals, penguins, whale sharks and coral reef fishes (DeBose et al. 2008).
DMS is a byproduct of the metabolic decomposition of DMSP in marine phytoplankton (notably Phaeocystis in the Southern ocean) and other marine algae (including zooxanthalae in coral reefs) (Nevitt, 2000). DMS is frequently associated with oceanic features where phytoplankton are plentiful, including upwelling zones, seamounts and shelf breaks. These are areas where seabirds and other marine predators tend to aggregate and forage (Nevitt and Bonadonna, 2005b; Nevitt et al., 1995). DMSP tends to be released when phytoplankton cells are crushed and it is then rapidly converted to DMS via processes within the marine microbial food web. DMS emissions increase when phytoplankton are grazed by zooplankton, suggesting that local elevations in DMS may opportunistically alert higher order predators (including birds) to rapidly accumulating aggregations of zooplankton (e.g. krill) and zooplankton predators (fish and squid).
DMS is involved in climate regulation through the production of cloud condensation nuclei. Biogenic marine DMS is a major contributor to geochemical sulfur cycling. Thus, considerable effort has been directed towards understanding and monitoring its production and distribution in the marine environment, extending from local (prey patch size) to global spatial scales. It is arguably unprecedented to have such detailed information on the production and distribution of a biogenic signal molecule, and these data have provided important insights into how seabirds and other marine organisms might use scented compounds in foraging and navigation at both local and global spatial scales. See Nevitt 2008 for a recent review of this topic. (Top: testing whether coral reef fishes can detect DMSP in Curacao (Debose et al. 2008, Science).
2). Olfactory behaviors in birds. While most of my work has focused on the procellariiforms, I am broadly interested in the sense of smell in birds. Birds use chemical cues for a variety of behaviors, but olfaction and taste are largely ignored in behaviors from foraging to communication and sexual selection. We were among the first groups to show odor-mediated individual recognition in birds. Long-lived Antarctic prions recognize the odor of their mates (Bonadonna and Nevitt 2004, Science) and leach’s storm-petrel chicks can recognize the individual odor signature of their nest (O’Dwyer et al. 2008). In collaboration with Henri Weimerskirch of CNRS / France, we were the
3). Phenotypic plasticity in endangered fishes. Threatened and endangered fish species are often removed from natural environments to be reared and bred in captivity until habitat can be restored. While most conservationists tend to be concerned about preserving genetic structure, it is common for fishes to adjust to artificial rearing by changing their behavior and even their morphology. Research from our lab showed that salmon reared in hatcheries have smaller brains by a variety of measures than genetically similar individuals reared in the
