Impacts Of Habitat Fragmentation On The Cranial Morphology Of A Threatened Desert Fish (Cyprinodon Pecosensis), Michael Chaise Gilbert
Impacts Of Habitat Fragmentation On The Cranial Morphology Of A Threatened Desert Fish (Cyprinodon Pecosensis), Michael Chaise Gilbert
Masters Theses & Specialist Projects
Drastic alterations to the North American Southwest’s hydrology have highly influenced resident fish communities. In New Mexico and Texas, the Pecos River has been severely altered as a result of water manipulation, isolating backwaters and various habitats that were once connected to the main river. Cyprinodon pecosensis (Pecos pupfish) has been highly impacted due to the effects of anthropogenic water manipulation, as well as species introductions. Cyprinodon pecosensis populations have become isolated and scattered, residing in sinkholes, remnant lakes, and static backwaters, thus creating numerous micropopulations. The purpose of this study was to assess the morphological variation in cranial features …
Modulation Of Prey-Capture Kinematics And Suction Feeding Performance In Smallmouth Bass, Micropterus Dolomieu, Andrea Sejdic
Modulation Of Prey-Capture Kinematics And Suction Feeding Performance In Smallmouth Bass, Micropterus Dolomieu, Andrea Sejdic
Masters Theses & Specialist Projects
The feeding behavior of fishes is a topic that has piqued the interests of many researchers given the dynamic and ancestral nature of aquatic prey-capture. This study examines aquatic feeding in terms of the suction and ram components of feeding in smallmouth bass, Micropterus dolomieu, and how they modulate their kinematic behavior when attacking pelagic and benthic prey. Relative to other Micropterus genera, the reduced gape in smallmouth bass suggests they may create considerable suction pressure – stronger subambient pressure pulled through a smaller opening creates greater velocity. Suction feeding is useful when feeding on benthic prey, such as crayfish. …
