Master’s Programs
   
The Department of Biology offers several degree options for students wishing to pursue graduate study at the master’s level.  Incoming students must select one of seven degree options: the Master of Science with a major in Biology (thesis or non-thesis), the Master of Arts with a major in Biology (thesis), the Master of Education with a major in Biology (non-thesis), the Master of Science with a major in Aquatic Resources (thesis), the Master of Science with a major in Population and Conservation Biology (thesis), or the Master of Science with a major in Wildlife Ecology (thesis).  Thesis-requiring degrees are usually chosen as preparation for professional careers or advanced graduate work (Ph.D., D.V.M., or M.D.) and by students seeking advanced training for technology-related industries.  Non-thesis degrees may be chosen by students preferring broad training in biology without a formal research experience; this plan is often chosen by secondary science teachers wishing to broaden their content training without taking additional education courses.
   
Master of Science in Biology.  The thesis-based Master of Science degree with a major in Biology requires a minimum of 30 semester hours of course work including three one-hour seminars (BIO 5110, 7102, or 7120) or BIO 5295 and two one-hour seminars, two semesters of thesis (BIO 5399A/B), and a minimum of 21 additional hours of 5000- or 7000-level Biology course work.  The non-thesis Master of Science degree with a major in Biology requires a minimum of 45 semester hours of 5000- or 7000-level course work, including at least one semester of an independent study project (BIO 5390) and either three one-hour seminars (BIO 5110, 7102, or 7120) or BIO 5295 and two one-hour seminars.  A supporting minor for these degrees may be selected with the approval of the appropriate graduate advisor.
   
Master of Arts in Biology.  The thesis-oriented Master of Arts degree with a major in Biology has the same requirements as outlined above for the Master of Science degree, except it permits substitution of non-science course work for students wishing to have a graduate minor outside of the College of Science.
   
A maximum of two courses offered by in other departments may be substituted for elective course work towards the M.S. and M.A. in Biology degrees with prior approval of the graduate advisor and Dean of the Graduate College.  Courses taught outside the department that do not require prior approval are:  CHEM 5385; HR 5330, 5331, 5339, 5351; and GEO 5415, 5417, 5418, and 5419.
   
Master of Science in Aquatic Resources.  The Master of Science with a major in Aquatic Resources is a thesis-based degree that emphasizes research into aquatic ecosystems and the biological communities that they support.  This degree requires a minimum of 31 semester hours of course work including two one-hour seminars (BIO 5110, 7102, or 7120), a two-semester sequence of courses in statistics and experimental design (BIO 7405, 7406) and two semesters of thesis (BIO 5399A/B). Graduate students pursuing an M.S. in Aquatic Resources can select one of two areas of concentration for their course work and research: Aquatic Resources or Aquatic Systems.  Students in the Aquatic Resources concentration will focus on the biology and ecology of aquatic organisms and an understanding of the dynamics and management of aquatic ecosystems and must complete a minimum of seven hours of course work chosen from BIO 5336, 5415, 5419, 5470, 7328, 7356, 7422, and 7471.  Students in the Aquatic Systems concentration will focus on an understanding of the structure and functioning of aquatic systems as integrated physical, biological, and socioeconomic entities and will emphasize practices aimed at protecting, maintaining, and restoring the health and sustainable use of these resources.  This area of concentration encourages investigation of aquatic systems at the level of the watershed, as influenced by atmospheric and terrestrial processes, and requires students to complete a minimum of seven hours of course work chosen from BIO 5419, 7312, 7352, 7366, 7421, 7422, 7468 and 7471.  In addition to the requirements outlined above, all students pursuing an M.S. in Aquatic Resources must complete a minimum of eight additional semester hours of 5000- or 7000-level elective courses chosen in consultation with the thesis advisor.
   
Master of Science in Population and Conservation Biology.  The M.S. with a major in Population and Conservation Biology requires a minimum of two years full-time course work and research leading to a thesis.  The program represents an interdisciplinary course of study that combines principles of population biology with strong training in measurement and analysis of biological systems, augmented with the student's choice of study in particular specialties.  Students are required to complete a two-semester core-course sequence (BIO 7427, 7428) and a two-semester sequence of courses in statistics and experimental design (BIO 7405, 7406) in the first year.  The course of study also includes a two-semester sequence of population biology seminars (BIO 7120) and two semesters of thesis (BIO 5399A/B), as well as elective courses that allow students to specialize in particular sub-disciplines of the field, including the ecology of populations, population management, conservation biology or evolutionary ecology and genetics.
   
Master of Science in Wildlife Ecology.  The M.S. in Wildlife Ecology is a thesis-based degree with an emphasis on the application of ecological principles to studies in the fields of wildlife ecology and natural resource management.  This degree requires a minimum of 30 semester hours of course work including two semesters of statistics and experimental design (BIO 7405, 7406), three one-hour seminars (BIO 5110) or BIO 5295 and two one-hour seminars, two semesters of thesis (BIO 5399A/B), and a minimum of 13 additional hours of 5000- or 7000-level courses that relate to the student’s area of interest.
   
Master of Education.  The non-thesis Master of Education degree with a major in Biology requires a minimum of 40 semester hours of course work including three one-hour seminars (BIO 5110, 7102, 7120) or BIO 5295 and two one-hour seminars, and a minimum of 7 additional 5000- or 7000-level Biology courses.  A minor is required and can be in a single discipline or can be split between a first and second minor.
Admission Policy
   
Applicants to any of the master’s programs in Biology should have a bachelor’s degree in biology or a related discipline with a comparable program of course work.  All applicants must submit a Graduate College Application for Admission, one official transcript from each university or college attended, and the official scores (verbal and quantitative) of the Graduate Record Examination (GRE) to the Office of the Graduate College.
   
Each applicant must also provide a current curriculum vitae, a statement of goals that describes his or her professional aspirations and rationale for pursuing graduate study in biology, and three letters of recommendation.  Applicants for any thesis degree must also provide an “Intent to Mentor” letter from a Biology Department faculty member.  In this letter, the faculty member must agree to serve as the student's initial thesis advisor.  The purpose of the mentor requirement is to help ensure that students have a successful start to their graduate careers.  These materials should be sent directly to the graduate advisor of the program to which the student is applying.  A current listing of faculty and their research interests, contact information for both graduate advisors and faculty, and further details on the various master’s programs can be found on the department’s web site: www.bio.txstate.edu.
   
The Department of Biology requires that a student have a minimum GPA of 3.0 on the last 60 undergraduate semester hours taken before receipt of the bachelor’s degree and a preferred GRE combined score (verbal and quantitative) of 1000 or higher for unconditional admission to be considered.  Students with grade-point averages below 3.0 may petition the department for conditional admission.  Admission in these cases will be decided by the appropriate graduate advisor based on interviews, letters of recommendation, research experience or other considerations that indicate the student’s ability to complete the graduate degree requirements.  The graduate advisors will determine if any background deficiencies exist and may require course work in addition to that necessary for a graduate degree to correct these deficiencies.
   
To receive full consideration, complete applications should be received by June 15 for admission the following fall semester, October 15 for admission the following spring semester, and April 15 for admission the following summer session.  The Graduate College will continue to process applications received after these deadlines, however, such applications will be processed on a first-come, first-served basis, with no guarantees of admission for those who apply after the deadline.
   
Admission of international students.  International applicants to any of the master’s programs in the Department of Biology must submit all required materials outlined above as well as meet other specific Graduate College admission requirements outlined elsewhere in this catalog and available on the Graduate College web site.  To receive full consideration, complete applications from international students should be received by June 01 for admission the following fall semester, October 01 for admission the following spring semester, and March 15 for admission the following summer session.
Thesis Students
   
Students pursuing a master’s degree with thesis should have a thesis committee approved by the end of their first long semester of enrollment in the graduate program.  The thesis committee comprises three or more individuals and is chaired by the thesis advisor.  Committee members should be selected by the student in consultation with the thesis advisor and should be chosen on the basis of what they can contribute to the student’s research and/or graduate studies.  Committee members expect to be consulted about the research project and should contribute guidance and expertise to the project.  A “Master’s Committee Application” form can be downloaded from the Biology Department web site and must be approved by the chair of the department’s Graduate Committee prior to the submission of a Thesis Proposal.
   
Students working on a thesis are expected to enroll in a thesis course (BIO 5399) each semester that they are actively involved in research.  Students should enroll in BIO 5399A for their first semester of thesis research and in BIO 5399B for all subsequent semesters.  While enrolled in BIO 5399A the student should prepare a detailed Thesis Proposal that introduces the project to be investigated, summarizes the relevant background literature, and explains the methodology to be used in carrying out the research.  A “Master’s Thesis Proposal” form can be downloaded from the department’s web site.  Submission of an approved Thesis Proposal to the Office of the Graduate College must be completed before the end of the student’s second semester of enrollment in BIO 5399.  Students pursuing a thesis-based degree must be enrolled in BIO 5399 during the semester in which they graduate.
   
All students completing a thesis are required to present the results of their research in an open seminar attended by the thesis committee members and other interested individuals.  Following the public presentation of the thesis, the student must pass a comprehensive examination administered by the thesis committee.
Non-Thesis Students
   
Students pursuing a non-thesis degree are required to have a major professor by the end of their first long semester of enrollment in the graduate program.  The major professor will normally be a faculty member specializing in an area of particular interest to the student and is often the individual who supervises the required independent study project.  Prior to the final semester of enrollment the non-thesis student must, in consultation with the major professor, select a committee that will administer the final comprehensive examination.  A “Master’s Committee Application” form can be downloaded from the Biology Department web site and must be approved by the chair of the department’s Graduate Committee.
Comprehensive Examination
   
All candidates for master’s degrees in the Department of Biology must pass a comprehensive final examination administered by the student’s committee.  The examination may be oral or written and must cover, at a minimum, the student’s field of concentration and the thesis, if one was written.  The results of this exam should be reported on the “Comprehensive Examination Report for Master's Degree” form, which can be downloaded from the department’s web site and which must be filed in the Office of the Graduate College at least 10 days prior to the date of expected graduation.
Financial Aid
   
Assistantships and scholarships are available to qualified applicants on a competitive basis.  The Department of Biology offers a limited number of graduate instructional assistantships to full-time students enrolled in the master’s program.  These assistantships are renewable based upon an annual review of each student’s progress and performance.  Faculty members may also have funds available to support students as research assistants.  Support is normally limited to two years.
   
The Office of the Graduate College can provide information concerning the availability of graduate scholarships.
