Newfoundland’s Banded Killifish (Fundulus diaphanus) population is listed as a species of Special Concern under Canada’s Species at Risk Act and Vulnerable under Newfoundland and Labrador’s Endangered Species Act. Mummichog (Fundulus heteroclitus) is a similar looking fish species and is currently under review by Newfoundland and Labrador’s Species Status Advisory Committee. Both species have limited known distributions in Newfoundland waters that overlap. They may occur sympatrically in estuaries and occasionally hybridize; thus, field identifications can be challenging. We found that dorsal fin position and caudal fin depth were the most useful morphological characters for distinguishing Banded Killifish and Mummichog in the field. We used local ecological knowledge, literature review, museum records, and field surveys to update the known distribution ranges and found both species in more locations than previously documented in Newfoundland. Thus, we extend their known ranges. Our results will be critical in future status assessments of these species in Newfoundland.

There are many integrity gaps in the federal and provincial systems designed to protect endangered and threatened species in Canada. NGOs (Non-governmental organizations) and other stakeholders can get involved in the process of protecting species at risk, by participating in collaborative efforts through volunteerism and stewardship efforts. NGOs can also bring issues of species-at-risk protection to court through litigation. This thesis began by exploring the integrity gaps in the federal and provincial processes for species at risk protection. The thesis then examined different initiatives undertaken by NGOs to combat this issue, the first being litigation and how it can be used as a strategy to help protect species at risk, and hold government accountable. The thesis also explored the rationale behind NGO actions, as well as the possible outcomes from these court cases. Next, the thesis discussed volunteer efforts undertaken by NGOs and other stakeholders. The research was supplemented with valuable qualitative interview data from scientists, members of NGOs, members of government, and a lawyer. The thesis concluded with recommendations for further action and policy measures that can be taken to protect species at risk
