Course name: Tropical Ecology
Course code: ENV 3044
Total contact hours: 60 hours

COURSE DESCRIPTION
This course will provide students with a general overview of tropical ecology. Students will gain insight about basic ecological concepts and be able to explore a variety of ecosystems, their animals and the multiple and complex ecological interactions that can be found in these areas. Costa Rica is a tropical country with an immensely rich biodiversity and for this reason a very representative area to these studies. Emphasis will be given to the study of the ecosystems found in Costa Rica, but others will be discussed as well.

OBJECTIVES
1) Become acquainted with the concepts and issues addressed to ecology.
2) Learn the characteristics of the major tropical ecosystems on earth.
3) Observe different ecosystems and seek examples of important interactions.
4) To become familiar with the biodiversity of the tropics.
5) Understand the importance of the balance and the harmony among different types of ecosystems.
6) Understand the natural and human made impacts on natural ecosystems.
7) Comprehend the importance of conservation and management of natural systems.

COURSE PRE-REQUISITES
It is recommended, but not required, that students complete a basic biology course prior to entering this course

METHODOLOGY
Audience
This course is structured for International Students attending the Study Abroad program at Universidad Veritas. However, courses are not exclusive to foreigners so a few native student could enroll in this course.

Electronic devices:
The use of cell phones, smart phones, or other mobile communication devices is disruptive, and is therefore prohibited during class. Please turn all devices OFF and put them away when class begins. Devices may be used ONLY when the professor assigns a specific activity and allows the use of devices for internet search or recording. Those who fail to comply with the rule must leave the classroom for the remainder of the class period.

Attendance
Students are only allowed 2 absences (justified or not). The student will fail the course if he/she has more than 2 absences. Students will have a 0 on any assignment evaluated in class (presentations, evaluations, field trips, etc.) if he/she is absent in this class, unless an official document is presented to justify the absence the class after the absence. In this case the assignment will be done this day. An unjustified absence to a fieldtrip will immediately mean failing the course. You can only have two total absences in your elective courses HOWEVER, if you miss more than one day of class in a given month, YOU WILL NOT RECEIVE CREDIT for that particular course.

Behavior
Professors have the right to expel a student from the classroom should he / she:
1) be disruptive in the classroom
2) be under the influence of alcohol or even smell like alcohol
3) Behave in a disrespectful way.
If you tend to be late for class, you will lose 25% of your total grade

LAB HOURS (complementary to the Field sessions there will be approximately 6 to 10 hours of class conducted in the Laboratory)
1. Students will learn to correctly operate a compound microscope, know its basic parts, and be able to put it away properly
2. Students will learn to differentiate between microscopic organisms at the Kingdom level (Protista, Fungi, Animalia)and the conditions in which can survive
3. Students will be able to observe in the stereoscope, study and hypothesize about the adaptations of seed structures to aid in their dispersal.
4. Students will learn to recognize the different morphological adaptations or interaction with animals, which may have the plants in order to survive

Assignments
Individual Presentation
Students will have to make an individual presentation (power point) through the course. The presentation must be about any subject concerning tropical ecology, approved by the professor. It must last about 15 min and should be emailed to the professor the day before. The professor, depending on the subject will assign the date for the presentation. The class will assign 30% of the grade and the professor will assign the remaining 70%.
Group Research Assignment
The assignment will be a research on any subject from unit 6, and it will consist of a powerpoint presentation.
For the presentation each group member has to talk at least for 5 minutes and the presentation should be at least 15 min and no longer than 30 min. One grade will be assigned for the group as a whole.
For All Presentations:
It will be evaluated based on preparation (knowledge assimilation), presentation style (organization, smoothness, and clarity), slides (clarity, aesthetics), finishing the presentation in time, and answering questions. All presentations must be made on the assigned date, if not the grade will be 0 (unless the absence is justified).

Debates:
Debates will be by groups which will depend on the number of students in the class. Half of the students will adopt the PRO side while the other half adopts the CON side. There will be 25 min per debate: 4 min per side for opening statements, 4 min per side for counter-arguments to each other's opening statement, and 4 min per side for closing remarks. The grade for the debate will be assigned by the course professor (70%) and the class (30%).
Fieldtrips
This course includes two mandatory Laboratory Field Trips: (choices will depend on climate and animal activity); probably one in the Pacific side, and one in the Caribbean side of the country. Lodging and main meals are covered by the course,
The mandatory fieldtrips in this course are not excursions. Only students enrolled in this course may attend. Field work might include volunteer work such as trail cleaning, late night species monitoring, long walks on beaches or dense vegetation areas and other tasks that might be considered harsh or strenuous for students who have not taken an environmental science course or have not done fieldwork. Students must be on time for all fieldtrip related activities including departure, return and scheduled meal times. All though many of the reserves and parks have nearby modest lodge accommodations some of the stations or research areas might require tent lodging. Some of the national parks and reserves are in far away areas of the country or places with difficult access so students who get motion sickness from long bus rides might be uncomfortable in these fieldtrips.
Fieldtrip Grade
Students will carry small note books to write down anything they see or learn while in the field and what they think about it. Each person?s journal will be unique to them, not only in that you will each notice different things, but you will each interpret similar things differently. This journal will help the students write their fieldtrip report, which is a formal paper of your journal information.
The fieldtrip report (70% of the fieldtrip grade) contains information of what the student sees and learns in the fieldtrip and what they think about the fieldtrip. The report should be no less than two 1.5-spaced pages (not including images) with #12 Times New Roman font, in letter size pages
Additionally, the behavior during the fieldtrip (30% of the fieldtrip grade) will be evaluated (punctuality, participation, etc.)
For all Written Assignments
All written assignments will be uploaded to Moodle. All assignments will have a deadline to be sent, and will not be received after this deadline, without exceptions. It is each student?s responsibility to be aware of the deadline (shown on Moodle for each assignment).
