Synchronization Of Reproduction In Deertoe Mussel (Truncilla Truncata), Kendell R. Loyd
Synchronization Of Reproduction In Deertoe Mussel (Truncilla Truncata), Kendell R. Loyd
MSU Graduate Theses
Freshwater mussels, Order Unionoida, are diverse and widespread in North America but have suffered general decline and many extinctions in recent decades. The reproductive biology of Unionoida is complex and may be vulnerable to human impacts. Male mussels release aggregates of sperm called spermatozeugmata that drift downstream. Females obtain spermatozeugmata from the water and brood the fertilized eggs internally during development. Many aspects of general reproductive biology are poorly understood, including the mechanisms that coordinate spawning and the route by which sperm meet eggs in the female. The present study focuses on reproduction in the Deertoe (Truncilla truncata), …
Maximum Entropy Modeling Of Indiana Bat (Myotis Sodalis) Maternity Roost Habitat, Joseph Robert Lemen
Maximum Entropy Modeling Of Indiana Bat (Myotis Sodalis) Maternity Roost Habitat, Joseph Robert Lemen
MSU Graduate Theses
Since 1967, the Indiana bat (Myotis sodalis) has been on the U.S. Endangered Species list due to disruption of hibernating bats in caves, summer habitat degradation, and more recently, the onset of White-nose Syndrome. The purpose of this study is to evaluate landscape variables associated with Indiana bat maternity roost trees in an attempt to better understand what factors play a role in their distribution in north central Missouri. I tracked reproductive female Indiana bats to 20 different primary and secondary roost trees; these are roosts that had multiple bats visit them on multiple occasions. GPS location data for these …
