Feel like you're drifting though life? A long way from home? Misunderstood? Odds stacked against you? Maybe you're a marine plankter. If so, Mike has a place you can stay; it's small, cold, and dark, but it's got a door and we'll get you liquored up for free. If that kills you (which it will), we'll give you PCR. It won't bring you back to life, but it will immortalize you in one of a series of fabulous studies of scyphozoan phylogenomics, comparative biogeography and phylogeography, marine population genomics, rapid evolutionary radiation in marine zooplankton, conservation genetics of marine fishes, or the community ecology of marine lakes.

Dr. Giovanni Rapacciuolo (July 2017 - present)

Gio

 


 

 

 

Gio is a Postdoc within the Dimensions of Biodiversity project on Palau marine lakes. His research focuses on the spatiotemporal drivers of biodiversity and extinction risk across a variety of ecological systems. Additionally, he is interested in the detection and attribution of species’ recent range shifts using historical data sources, such as repeated ecological surveys and museum specimens.

I am a marine biologist by training and a postdoctoral scholar with the UC Conservation Genomics Consortium. My general interests include the origins and maintenance of variation in natural populations. Marine mortality events can cause a rapid change of variation in populations over wide geographic scales. At the Dawson lab, I work on the genomics of the sea star, Pisaster ochraceous. We examine how Pisaster populations respond to the sea star-wasting disease. My aim is to characterize how the sea star-wasting disease affects sea star populations by looking at genome-level responses to the disease.

I use population genomic techniques to study how mass mortality can reshape biodiversity. I’m interested in clarifying the evolutionary consequences of disturbance to better understand how we can maintain stability and viability of marine populations in a changing climate. The 2013 sea star wasting disease pandemic in Pisaster ochraceus provided a rare opportunity to disentangle the dynamic interaction between natural selection, dispersal, and extreme conditions as it unfolds. With before-and-after samples bracketing the mass mortality I aim to explore the genetic consequences of the event, trajectory of recovery in survivors and offspring, and implications for future events.

I'm an evolutionary ecologist, and most of my research focuses on the interplay between ecological genetics (e.g. local adaptation, rates of inbreeding) and the distributions of marine 'plants', mostly macroalgae and seagrasses. In the Dawson lab, I am contributing to a multicampus collaboration with University of California PIs Mike Dawson, Rick Grosberg, Pete Raimondi, Brian Gaylord and John Largier funded by the University of California's Coastal Environmental Quality Initiative. The goal of this project is to begin to explore the links between (1) community characteristics such as species diversity, abundance patterns, and similarity in composition across sites, (2) population genetic characteristics, including genetic diversity, patterns of allelic richness, and genetic structure across sites, of common invertebrate and algal species found in rocky intertidal habitats along the California coastline, and to examine those links in light of (3) the nearshore physical oceanography of this region and hypothesized patterns of connectivity among sites.

Keith and wallaby

 

I am interested in the molecular systematics, phylogeography, population genetics and invasion genetics of scyphozoan jellyfish and ctenophores. I am working on the NSF funded REVSYS project (a collaboration between the Dawson Lab and Allen Collins at the Smithsonian Institution) examining the phylogenetic relationships, both molecular and morphological, among the semaeostome jellyfish (Cnidaria: Scyphozoa), a group that includes moon jellies, sea nettles and the lion’s mane jellyfish of Sherlock Holmes' fame. Although these jellyfish cause extensive problems worldwide as blooming and invasive species, taxonomic knowledge of this group (as is true of jellyfish in general) is relatively poor. By combining morphological and genetic data, we will greatly contribute to knowledge of species diversity within the group, morphological characters that delineate species and evolutionary relationships among species.
