“…Furthermore, we observed frequent obstacles to travel tended to be unpredictable substrates, in which branches snapped as a monkey was poised to leap, woody walkways abruptly collapsed and tumbled downward, winds swirled canopies in chaotic manners, and other unpredictable events that sent primates into abrupt, chaotic postures. We took note of these actions; however, habitat data that provided the greatest reliability and gave the best sense of the structural character of the arboreal habitat was canopy connectivity, based on descriptions by Madden et al (2010), andRaboy et al (2004). By climbing into various tiers of the forest, we found canopy connectivity extending in vertical and horizontal directions, with each calculated category of connectivity (open, semi-open, closed) speeding or slowing down our progress accordingly as we moved through canopies (Fig.…”

“…While such breaks in forest canopies disrupt navigation through arboreal habitats, foraging for food is often optimal in fragmented patches of rainforest where ecological edge habitats typically foster patchy, high concentrations of food for primates (Arroyo-Rodríguez 2007, Emmons & Gentry 1983, Worman & Chapman 2006. Canopy complexity and the scattered resources typical of a neotropical primate's niche favors individuals that employ extreme finesse and wide-ranging appendicular mobility as they forage for food, maintain contact with their social troop, and escape from arboreal and aerial predators (Bezanson 2009, Garber 1992, Madden et al 2010, Smith 2000.…”

“…Field research began 1 hour before sunrise along forest trails where we listened for calls and movements of primates. We quietly followed a primate troop for an hour, allowing them to habituate to our presence, at which time we employed observational instantaneous sampling of 30 second intervals (Madden et al 2010, Suen & Ary 1984 …”

“…Tape measures were used to determine mean distance to nearest forest clearing (≥ 75% light penetration determined by densiometer), which were typically gaps in the overhead canopy caused by treefalls, physical processes such as stream action or human activity (Madden et al 2010;Sanford et al 1986, Schnitzer & Carson 1991.…”

Movement ecology of arboreal monkeys in Central America involves the action of diverse body postures to address challenges in rain forests, where scattered resources and complex habitat structure demand that a primate frequently employ extreme physical finesse to survive. What is not clearly understood about this area of study is the connection between primate body postures as responses to specific types of forest architecture and how forest structure may influence a monkey's continued capacity for wide-ranging mobility over time. We studied tree canopy structure and branch connectivity associated with the movement ecology of black-handed spider monkeys (Ateles geoffroyi), mantled howling monkeys (Alouatta palliata), Geoffroy's tamarins (Saguinus geoffroyi), and white-faced capuchins (Cebus capucinus) in Panama and Costa Rica. Laboratory study of primate cadaver pelvises was done at UC Davis, Oregon Osteology Lab, and the Denver Museum. Rain forests appear to induce wide-ranging leg movements in wild neotropical monkeys that were not observed in the same species of monkeys inhabiting artificial environments. We also found that a wild primate employs frequent wide-ranging leg movement that result in widely dispersed contacts between the articulating surfaces within the hip, potentially maintaining cartilage and contributing to the longevity of that joint. Thus, a connection may exist between rain forests, the leg action of wild monkeys, and the continued capacity to move over time in this group of long-lived animals. postures as responses to specific types of forest architecture and how forest structure may influence a monkey's continued capacity for wide-ranging mobility over time.

“…These students recognized that areas of the forest used by tamarins contained ample data from which to work. By addressing the environment as part of a behavioural study, students made discoveries in the field that gave rise to a canopy-connectivity theory, an explanation about how small primates select routes through rainforests (Madden, Garber, Madden, & Snyder, 2010).…”

Teachers may use apprenticeships and collaboration as instructional strategies that help students to make authentic scientific discoveries as they work as amateur researchers in academic field studies. This concept was examined with 643 students, ages 14-72, who became proficient at field research through cognitive apprenticeships with the Smithsonian Institute, School for Field Studies and Earthwatch. Control student teams worked from single research goals and sets of methods, while experimental teams varied goals, methods, and collaborative activities in Kenya, Costa Rica, Panama, and Ecuador. Results from studies indicate that students who conducted local pilot studies, collaborative symposia, and ongoing, long-term fieldwork generated significantly more data than did control groups. Research reports of the experimental groups were ranked highest by experts, and contributed the most data to international science journals. Data and anecdotal information in this report indicate that structured collaboration in local long-term studies using apprenticeships may increase the potential for students' academic field studies contribution of new information to science.
