List of potential advisers SSI 2014 BOTANY Dr. Dylan Burge, Curator dburge@calacademy.org 415-379-5364 Understanding the evolution of ecological traits remains one of the greatest challenges for biologists of the twenty-first century. The threat of major biodiversity losses due to humancaused climate change makes the task even more urgent. One of the most important ecological factors limiting the growth and survival of plants is the relationship between plants and their soils, also known as edaphic ecology. Unfortunately, scientists have only a limited understanding of how plants adapt to unusual soils, and how this phenomenon influences the overall evolutionary trajectory of plant lineages. Dylan Burge’s Research uses molecular phylogenetic, genomic, and population genetic tools, combined with experiments, to test hypotheses on the role that soil chemistry plays in plant adaptation, speciation, and diversification. Dylan works on these problems in several groups of plants, including California lilacs (Ceanothus), jewel flowers (Streptanthus), and incense cedar (Calocedrus). Other project include floristic analyses in north America (quantitative floristics), and the evolution of phenology in wine grapes. Dylan welcomes applications from potential interns interested in any of these projects, but is especially interested in students who wish to learn more about genomic analysis and plant adaptation. 1 BOTANY Peter Fritsch, Curator pfritsch@calacademy.org 415-379-5356 Peter Fritsch received his Ph.D. in 1995 from the Rancho Santa Ana Botanic Garden Program in Botany and the Claremont Graduate School. He joined the Academy's staff in 1996. His primary research focuses on the systematics, biogeography, and evolution of the flowering plant order Ericales, a group that includes the blueberries (Vaccinium), wintergreens (Gaultheria), and persimmons (Diospyros), among many others. Many of the plants in this order are disjunct relicts, which means that they were once widespread but are now restricted in range to discrete and widely separated areas of the earth due to climate change. Dr. Fritsch uses a combination of morphological and molecular approaches on these groups to understand their species diversity, evolutionary relationships, and adaptations to particular environments. These studies can lead to a better overall understanding of the effects and significance of climate change on the world's biota. Potential Project: The wintergreen group of the heath family of flowering plants (Ericaceae) contains several genera, the largest of which is Gaultheria, containing about 100 species. This genus is the original source for oil of wintergreen (methyl salicylate), commonly used in candies and as a topical pain reliever, and has been defined partly by the presence of this compound in the species of the genus, and also by the possession of a brightly colored fleshy persistent calyx in the fruiting stage. Recent evidence from DNA sequence data shows that the genus does not form a natural group because the other genera of wintergreens, i.e., Tepuia from northern South America and Diplycosia from Southeast Asia, are phylogenetically nested within it. We will develop a revised classification for the wintergreen group using morphological characters as mapped onto the phylogenetic tree derived from molecular data. We will create dichotomous keys and, time allowing, an interactive key to the clades in this group. Mapping the morphological characters on the tree will test the adaptive value of methyl salicylate and other characters in the group, and the re-classification will be important for facilitating communication about this group in biodiversity and conservation studies in which its constituent species occur. 2 ENTOMOLOGY Dr. Brian L. Fisher, Curator at CAS; Adjunct Professor at UC Berkeley bfisher@calacademy.org Often found hip-deep in Madagascar mud, Brian Fisher is a modern day explorer who has devoted his life to the study and conservation of ants and biodiversity around the world. He created the annual Ant Course in 2001, AntWeb in 2002, and the Madagascar Biodiversity Center in 2004. His research sends him through the last remote rainforests and deserts of Madagascar and Africa in search of ants. Although his subjects may be small in stature, they make a huge impact on their ecosystems. And what they lack in size, they more than make up for in numbers. The SSI intern will conduct research with Brian and other members of the Ant lab to study the evolution and taxonomy of male ants. They will learn specialized imaging and dissection techniques to discover morphological characters to distinguish ant genera in Madagascar. Depending on the outcomes of the research, the results will be published with the SSI intern as an author. 3 ENTOMOLOGY Dr. Charles Griswold, Curator, Schlinger Chair cgriswold@calacademy.org 415-379-5312 Charles is Curator of Arachnida at CAS and Adjunct Professor at San Francisco State University and University of California at Berkeley. He studies arachnid evolution and biogeography with a worldwide focus. This year’s SSI intern will conduct research with Charles and other members of the Arachnology lab to study the evolution and taxonomy of harvestmen (see above) or spiders. The intern will compile, analyze and integrate taxonomic, phylogenetic and biogeographic information. Tools will include light and scanning electron microscopy, comparative anatomy and morphology, molecular phylogenetics and DNA “barcoding”, and Geographic Information Systems (GIS). There is more about Charles and his lab at: http://research.calacademy.org/ent/staff/cgriswold 4 HERPETOLOGY Dr. David Blackburn, Assistant Curator dblackburn@calacademy.org 415-379-5375 Dave Blackburn studies the diversity and evolution of amphibians, especially frogs and especially in Africa. This work involves the discovery and descriptions of new species and determining evolutionary relationships. These pieces form the building blocks of larger studies focused on the deep-time history of Africa as well as how and why shapes and sizes of frogs change through time. A great deal of work is also now focused on understanding the origin, spread, and genetic diversity of a fungal pathogen implicated in declines and extinctions of amphibians. Potential projects include: descriptions of new species of frogs based on morphological and molecular data; testing hypotheses of the role of biogeographic barriers (such as rivers) in structuring the genetics of populations; estimation of higher-level relationships among lineages of African frogs using multi-locus DNA data; characterization of morphological diversity of male secondary sexual characters and interpretation of their evolution in a phylogenetic context; and analysis of fungal genetic diversity from recently collected field specimens. 5 ICHTHYOLOGY Dr. Luiz Rocha, Assistant Curator, Follett Chair lrocha@calacademy.org 415-379-5370 Luiz Rocha received his PhD from the University of Florida in 2003 and joined the Academy in 2011. His research interests and experience are centered on the evolution, phylogeography (or the geographic distribution of genetic lineages), biogeography, molecular systematics, genomics and community and behavioral ecology of coral reef and coastal marine fishes. He frequently tries to combine these fields, invoking ecology to help explain evolutionary patterns and using molecular tools to test biogeographic and systematic hypotheses. The overall objective of this interdisciplinary research is to test existing hypotheses (and propose new ones) about what generates and maintains the extremely high biodiversity in tropical coral reefs. Current projects include: 1) Phylogeography of Indo-Pacific and eastern Pacific reef fishes: using molecular markers to test biogeographic hypotheses and estimate species evolutionary histories. 2) Reef fish molecular systematics and taxonomy: using DNA sequences to estimate species relationships by generation cladograms, and compare DNA hypotheses with previously published morphological hypotheses. 3) Search for cryptic species: comparing DNA barcode sequences and morphological characters across several locations within a species to potentially find previously unrecognized taxa. 6 INVERTEBRATE ZOOLOGY & GEOLOGY Dr. Terrence M. Gosliner, Senior Curator tgosliner@calacademy.org Terry's research on the systematics, phylogenetics and comparative biology of nudibranchs and other sea slugs focuses on the implications of phylogenies in understanding evolution of shellloss, mimicry, and other comparative aspects of the evolution of these animals. He has studied the diversity of these mollusks along the California coast for more than 40 years. Most recently, this work employs evolutionary studies to develop new strategies for conservation of Philippine reefs in the center of the center of marine biodiversity. He develops key collaborations with research institutions, conservation organizations, and large public exhibits to bring these findings to diverse audiences. Potential projects include: 1) Systematics of Indo-Pacific nudibranchs. 2) Descriptions of new species of Philippine nudibranchs using molecular and morphological techniques.

He studies the systematics, phylogeny, paleontology, and biogeography of echinoderms, particularly sea urchins and sand dollars. His field work has included submersible dives off the Bahamas, paleontology in Alaska, ship-based collecting in Antarctica, and shallow- and deep-water expeditions in the Philippines. His research can be summarized as the study of the origins of evolutionary novelty, for which the Echinodermata constitutes an excellent model system. These studies are culminating in a theory that describes the homologies and evolutionary relationships among major clades throughout the phylum Echinodermata. Example projects include, but are not limited to: 1) Origin and evolution of the northeastern Pacific sand dollar fauna (Clypeasteroida: Echinoidea). An examination of both Recent and fossil genera to develop cladistic and morphometric analyses that will examine the origins of this fauna. 2) Phylogenetics of the clypeasterine sand dollars. Although there are over 40 nominal species in the genus Clypeaster, morphometrics will be necessary to determine validity of these with the hope of using specimens to develop characters for a phylogenetic analysis. 3) Phylogenetic placement and biogeographic studies of Philippine sea urchins from any of a variety of major groups collected during the expeditions of 2011, 2014, and 2015. 8 INVERTEBRATE ZOOLOGY & GEOLOGY Dr. Peter Roopnarine, Curator proopnarine@calacademy.org 415-379-5271 Peter Roopnarine received his Ph.D. in Geology from the University of California Davis, and also holds degrees in Biology and Oceanography. He has been with the Academy since 1999. He studies a variety of topics in paleontology and evolutionary biology, including the dynamics of extinction, modelling ancient and modern ecosystems, and the evolutionary paleoecology of tropical American marine molluscs. Together, these topics focus on developing a theoretical basis for understanding the role of ecological diversity in the evolution and extinction of species. Potential projects include: 1) Morphometric description and biogeography of a widespread genus of marine bivalves in the tropical western Atlantic, ranging from the Oligocene to the Recent. 2) Building a food web for the San Francisco Bay and related offshore habitats, including more than 1,300 species, using the Academy's collections and other data. 3) Examining evolutionary and ecological change in Miocene-Pliocene marine communities of the Dominican Republic using morphometric analysis, quantitative ecological analysis, and multiple species of molluscs.

His work involves coral communities from various parts of the world and includes coral reefs as well as deep-sea corals. Octocorals include some of the most beautiful and morphologically diverse animals in the world's oceans - these are the soft corals, sea fans, and sea pens. They are a group of corals characterized by having eight feathery tentacles surrounding the mouth of each polyp. Potential projects include: 1) Systematics and biogeography of corals in different biogeographic regions, as well as those restricted to a particular region – such as coral reefs of the Philippines in the western Pacific 2) From east to west – biogeographic comparisons of coral reef gorgonians between the South China Sea and the western Pacific 3) Distributional patterns of gorgonians and sea pens by depth.
