  • USF Board of Trustees ( March 7, 2013)
    Agenda item: (to be completed by Board staff) USF Board of Trustees ( March 7, 2013) Issue: Proposed Ph.D. in Integrative Biology ________________________________________________________________ Proposed action: New Degree Program Approval ________________________________________________________________ Background information: This application for a new Ph.D is driven by a recent reorganization of the Department of Biology. The reorganization began in 2006 and was completed in 2009. The reorganization of the Department of Biology, in part, reflected the enormity of the biological sciences, and in part, different research perspectives and directions taken by the faculty in each of the respective areas of biology. Part of the reorganization was to replace the original Ph.D. in Biology with two new doctoral degrees that better serve the needs of the State and our current graduate students by enabling greater focus of the research performed to earn the Ph.D. The well-established and highly productive faculty attracts students to the Tampa Campus from all over the United States as well as from foreign countries. The resources to support the two Ph.D. programs have already been established in the Department of Biology and are sufficient to support the two new degree programs. The reorganization created two new departments; the Department of Cell Biology, Microbiology, and Molecular Biology (CMMB) and the Department of Integrative Biology (IB). This proposal addresses the creation of a new Ph.D., in Integrative Biology offered by the Department of Integrative Biology (CIP Code 26.1399). The name of the Department, Integrative Biology, reflects the belief that the study of biological processes and systems can best be accomplished by the incorporation of numerous integrated approaches Strategic Goal(s) Item Supports: The proposed program directly supports the following: Goal 1 and Goal 2 Workgroup Review: ACE March 7, 2013 Supporting Documentation: See Complete Proposal below Prepared by: Dr.

Malaysia National Plan of Action for the Conservation and Management of Shark (Plan 2), Ministry of Agriculture and Agro- based Industry Malaysia, Putrajaya, Malaysia. 50pp SUMMARY Malaysia has been very supportive of the International Plan of Action for Sharks (IPOA-SHARKS) developed by FAO that is to be implemented voluntarily by countries concerned. This led to the development of Malaysia’s own National Plan of Action for the Conservation and Management of Shark or NPOA-Shark (Plan 1) in 2006. The successful development of Malaysia’s second National Plan of Action for the Conservation and Management of Shark (Plan 2) is a manifestation of her renewed commitment to the continuous improvement of shark conservation and management measures in Malaysia.

    06_250317 part1-3.qxd 12/13/05 7:32 PM Page 15 Phylum Chordata Chordates are placed in the superphylum Deuterostomia. The possible rela- tionships of the chordates and deuterostomes to other metazoans are dis- cussed in Halanych (2004). He restricts the taxon of deuterostomes to the chordates and their proposed immediate sister group, a taxon comprising the hemichordates, echinoderms, and the wormlike Xenoturbella. The phylum Chordata has been used by most recent workers to encompass members of the subphyla Urochordata (tunicates or sea-squirts), Cephalochordata (lancelets), and Craniata (fishes, amphibians, reptiles, birds, and mammals). The Cephalochordata and Craniata form a mono- phyletic group (e.g., Cameron et al., 2000; Halanych, 2004). Much disagree- ment exists concerning the interrelationships and classification of the Chordata, and the inclusion of the urochordates as sister to the cephalochor- dates and craniates is not as broadly held as the sister-group relationship of cephalochordates and craniates (Halanych, 2004). Many excitingCOPYRIGHTED fossil finds in recent years MATERIAL reveal what the first fishes may have looked like, and these finds push the fossil record of fishes back into the early Cambrian, far further back than previously known. There is still much difference of opinion on the phylogenetic position of these new Cambrian species, and many new discoveries and changes in early fish systematics may be expected over the next decade. As noted by Halanych (2004), D.-G. (D.) Shu and collaborators have discovered fossil ascidians (e.g., Cheungkongella), cephalochordate-like yunnanozoans (Haikouella and Yunnanozoon), and jaw- less craniates (Myllokunmingia, and its junior synonym Haikouichthys) over the 15 06_250317 part1-3.qxd 12/13/05 7:32 PM Page 16 16 Fishes of the World last few years that push the origins of these three major taxa at least into the Lower Cambrian (approximately 530–540 million years ago).
