Conservación Biológica Harakbut: Estudio De Caso Ori’Numba, Anya Held

Peru: Indigenous Peoples and Globalization

Through interviews, observations, and bibliographic research, this project investigates the Indigenous-based conservation project of Ori’Numba Garden. In 2018, the Tayori family moved to Ori’Numba and began transforming it from a former livestock farm into a holistic conservation project. The paper details the history of Ori’Numba and the process of its creation, the modern and traditional agricultural techniques used in the garden, a register of the pineapple and native bee species, and some of the relevant Harakbut mythology. Ori’Numba clearly demonstrates that there is Indigenous conservation biology, not just “indigenized” Western conservation biology.

Comparative Mechanical And Elastic Properties Of The Dorsal And Ventral Tendons In The Peduncle Of Harbor Porpoise (Phocoena Phocoena), Alexa R. Cesari, Jesse K. Placone, Nicole L. Ramo, Michael V. Rosario, Matthew Morris, Danielle S. Adams, Frank E. Fish

Biology Faculty Publications

Cetaceans swim via vertical movements of the tail. The tendons located in the caudal peduncle are attached to the caudal vertebrae to generate propulsive oscillations. Arguments have centered on whether the upstrokes and downstrokes of the tail and propulsive flukes are symmetrical or asymmetrical in time. Previous research from kinematics of swimming animals, muscle architecture and histology has supported both conditions. However, the composition and structure of the tendons suggest a potential mechanism to evaluate this disparity. In this study, the tendons of the caudal peduncle of the harbor porpoise (Phocoena phocoena) – specifically, the extensor caudae medialis …
