Habitat Selection And Host Detection In The Salamander Mussel, Simpsonaias Ambigua, Eric A. Stegmann
Habitat Selection And Host Detection In The Salamander Mussel, Simpsonaias Ambigua, Eric A. Stegmann
MSU Graduate Theses
The native freshwater mussels, Order Unionida, have suffered many species extinctions and loss of abundance. Two important threats to native mussels are loss of habitat and loss of access to the vertebrate hosts of the parasitic mussel larvae. The Salamander mussel, Simpsonaias ambigua, is a habitat specialist, living under flat rocks. It is often found in direct association with its only known host, the common mudpuppy, Necturus maculosus. This association could result from movement and habitat selection by the mussels themselves. Alternatively, it might result from the deposition of juveniles by a resident host. Habitat selection and host …
Pthr1/Sox9 And Idh1/Idh2 Relative Expression In Primary Chondrocyte And Chondrosarcoma Cells Under The Synergistic Influence Of Inducible Hypoxia And Extracellular Acidosis, Kostika Vangjeli
Biological Sciences Theses & Dissertations
Cartilage cells (Chondrocytes) grow in rather unique environmental conditions in the human body. Cartilage is avascular tissue and lacks innervation. Its main source of nutrients is derived from the synovial fluid and/or perichondrium. Consequently, these cells must survive and thrive under hypoxic and acidic stressors. Published data suggests that there are a multitude of genes affected from either one of these two stressors or both. However, these factors are frequently overlooked in cartilage research, and results are reported in either normoxia/pH=7.0 conditions, or they only account for one of the conditions. The scope of this study is to examine how …
