The Status Of Invasive Dusky Slug (Arion) Species In The Upper Great Lakes: A Molecular Approach, Olivia W. Hall
The Status Of Invasive Dusky Slug (Arion) Species In The Upper Great Lakes: A Molecular Approach, Olivia W. Hall
All NMU Master's Theses
I update the distribution of two cryptic slug species, Arion fuscus and Arion subfuscus, in the Upper Great Lakes of the United States using molecular identification methods. Arion fuscus has not previously been reported in the literature in this region, and Arion subfuscus has previously been reported as abundant. However, all previous distribution studies were determined using visual identification tools, which can result in misidentification between cryptic species. To molecularly re-examine these distribution maps, I used a mitochondrial ribosomal subunit 16S PCR amplification and subsequent SSpI and MfeI restriction enzyme digest to identify slug specimens. I collected slugs in …
Behavior, Nest Site Selection And Success Of Black Terns (Chlidonias Niger), Dawn Marsh
Behavior, Nest Site Selection And Success Of Black Terns (Chlidonias Niger), Dawn Marsh
All NMU Master's Theses
The Black Tern (Chlidonias niger) population has markedly declined over several decades in northern North America, the causes of which are still largely unknown. I monitored nest success and wetland use by Black Terns in three colony sites in northern Michigan throughout 2017 and 2018 and used traditional survey methods coupled with nest cameras to document Black Tern nest success and mortality events. Colony sites included in this study were experiencing invasion by non-native plant species including Phragmites, hybrid and narrow-leaved cattail (Typha spp.), and European frog-bit (Hydrocharis morus-ranae). Statistically significant differences (P …
