First, I will apply seminal terrestrial gait kinematics work to mammalian climbing to quantify the kinematic parameter space used by climbers. Second, I will examine scaling relationships of claw parameters to determine tradeoffs in grip and fragility in the context of providing suitable adhesion to the climbing surface. Third, I will propose analyzing the economy, or cost of transport, for different climbing strategies for animals of different masses to discern if there is an optimal speed to balance the cost of supporting body weight with the cost of doing mechanical work to actively climb. The overall goal of this proposal is to develop a predictive model for mammalian climbing and strategy informed by these understandings of kinematics, morphology, and energetics. \u003C\/span\u003E\u003C\/span\u003E\u003C\/span\u003E\u003C\/span\u003E\u003C\/span\u003E\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u003Cspan\u003E\u003Cspan\u003E\u003Cspan\u003E\u003Cspan\u003E\u003Cspan\u003EFinally, this research would not be possible without collaborations with zoological and wildlife institutions. Aside from being difficult to study in traditional laboratory settings, many mammalian climbers are threatened, endangered, or lack sufficient data to determine conservation status. I propose capitalizing on these interdisciplinary collaborations to promote conservation efforts locally and in the wild through research, education, and outreach.\u003C\/span\u003E\u003C\/span\u003E\u003C\/span\u003E\u003C\/span\u003E\u003C\/span\u003E\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\r\n","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003E\u003Cspan\u003E\u003Cspan\u003E\u003Cspan\u003E\u003Cstrong\u003E\u003Cspan\u003E\u003Cspan\u003E\u003Cspan\u003EMechanics and Morphology of Mammalian Climbing with Applications for Conservation\u003C\/span\u003E\u003C\/span\u003E\u003C\/span\u003E\u003C\/strong\u003E\u003C\/span\u003E\u003C\/span\u003E\u003C\/span\u003E\u003C\/p\u003E\r\n","format":"limited_html"}],"field_summary_sentence":[{"value":"Mechanics and Morphology of Mammalian Climbing with Applications for Conservation"}],"uid":"27707","created_gmt":"2023-09-12 13:46:52","changed_gmt":"2023-09-12 13:46:52","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2023-09-18T13:30:00-04:00","event_time_end":"2023-09-18T15:00:00-04:00","event_time_end_last":"2023-09-18T15:00:00-04:00","gmt_time_start":"2023-09-18 17:30:00","gmt_time_end":"2023-09-18 19:00:00","gmt_time_end_last":"2023-09-18 19:00:00","rrule":null,"timezone":"America\/New_York"},"location":"IBB 1128 (Suddath Seminar Room)","extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"102851","name":"Phd proposal"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
