Participant Acceptance Criteria: ANT COURSE is open to all interested individuals (professionals, motivated amateurs such as citizen scientists, undergraduate and graduate students, postdocs, and professors). Priority is given to applicants currently researching ants. An entomological background is not required. We aim to include students with diverse interests and experiences in biology, including systematics, evolution, ecology, behavioral biology, neurobiology, genetics, global change biology, and conservation. The high ratio of instructors to students allows all attendees to receive a great deal of individual attention. ANT COURSE is presented in English and limited to 17 participants. Photos from previous courses are available in the yearbook.

Cost: Lodging and meals covered while at the field station.  Participants must cover costs of a taxi from airport, meals, and hotel while in Cayenne [Hotel: 75€ for a single room (one single bed) and 90€ for a double one (2 single beds or a double one). Taxi: 25-30 € from the airport to Cayenne downtown and can be shared up to 3-4 people in a cab). Transportation costs between home and Cayenne are to be borne by all participants.

Sponsors. –California Academy of Sciences, Center for the study of biodiversity in Amazonia (CEBA).

The ANT COURSE Program

ANT COURSE is a workshop that includes three modules: I. Phylogeny, Diversity, Classification, II. The Social Dimension, and III. Roles in Ecosystems and Sustainability.

Ant Course is a unique opportunity to acquire training that is unavailable elsewhere. Lectures and laboratory practice emphasize classification, identification of ant genera, social systems, and the diverse roles ants play in ecosystems. Field trips teach skills such as collecting and sampling, live colony capture, and biomonitoring techniques. Associated lab work focuses on specimen preparation, sorting, labeling, dissection, and monitoring analysis. Information on equipment, literature, and myrmecological contacts are also shared.

This course will provide students with an appreciation of the following:

• Biological diversity and evolution of ants.
• Diagnostic characteristics of genera and some species.
• Field collecting and specimen preservation techniques.
• Use of identification keys.
• How ant societies function: division of labor, reproduction, communication, problem-solving.
• Role of ants in providing ecosystem services.
• Monitoring objectives and methods.
• Online tools for ant identification, natural history, and scientific communication.

ANT COURSE Schedule

I. Phylogeny, Diversity, Classification

Module one provides the framework for exploring and understanding of sociality and the role ants play in ecosystems and communities.

1. Phylogeny
2. Morphology
3. Classification
4. Identification
5. Curation
6. Macroecology/Biogeography

Field trip: focused on collecting methods, diversity of collections.

II. The Social Dimension

Ants exist not so much as individual organisms but rather as elements within a colony (within a family unit). Understanding this idea is key to appreciating how ants interact with the world.

1. Reproduction including dissection of ovaries.
2. Dispersal and Colony foundation.
3. Division of Labor: how are colonies organized? age and caste.
4. Communication underlies cooperation.
5. Colony members are not clones: Regulation of conflicts.
6. Perennial nests. Benefits of food exchange and storage (trophallaxis, trophic eggs, repletes)
7. A broad continuum between simple and complex societies.

Field trip: live colony capture for study.

Lab practical options with live colonies are done in groups of 3-4 students. Observations make it necessary to have a suitable container with fluon – note: each student should bring a plastic container.

• If the live colony was located after baiting foragers (as opposed to accidental finding, e.g. inside a rotten log), make general observations about worker activity (around entrance) and prey preferences *before* collecting colony.
• observe different brood stages (e.g. are pupae naked or enclosed in cocoon? how larvae feed?
• mark (color codes) a small sample of individuals, and observe their activities.
• how many queens?
• Do the same workers forage?
• Are there differences in behavior among morphologically distinct sub-castes?
• list differences between queens and workers (and males!), and relate to distinct functions in colony (= functional morphology). Assess degree of dimorphism in body size.
• dissect queen ovaries, check for developing eggs and "yellow bodies", check for sperm in spermatheca. Dissect the color-marked workers. If several queens, determine monogynous/polygynous?
• dissect thorax of queen (in alcohol): are wing muscles present or resorbed? infer about claustral/non-claustral foundation of colonies.
• Estimate/count colony size.
• Use agar plates to see what bacteria grow from ant guts.

III. Role in Ecosystem/Sustainability

Since ants are so ecologically important, can we do good science but also do good for society?

1. Community dynamics.
2. Diversity of diet: baiting, isotopes, mandible shapes, gut symbionts.
3. Invasive ants.
4. What role do ants play in ecosystem services?
5. Mutualisms with plants and insects.
6. Can the study of ants play a role in achieving conservation/sustainability goals?
7. How to design a monitoring program for ants and analyze monitoring data?
8. Ecological tolerance and life history of indicator species.

Field trip: explore community dynamics/role of ants in ecosystem.

Field Practical options:

• Student could be responsible for sampling in a specific quantitative manner (traps, winklers) and then compares diversity/occurrence before the end of the course. Students can sample diverse habitats or along disturbance gradients.
• Focus on a few ant-plants and ask if the communities / inhabitants change in relation to land use change or abiotic gradients.
• Investigate if introduced species are interacting with native fauna (behaviorally or in competition for next space or resources). This can be examined with baits.
• Big baiting experiment where students measure discovery / dominance tradeoffs in relation to habitat (arboreal versus ground) or bait type (protein versus carbohydrate).
• Students repeat the global picnic bait study to see which nutrients appear to be more limiting for different taxa or in different habitats.

Side workshops:

• Science Communication
• Conservation priorities for ants
