Tracking rapid landscape change with repeated photography, Gros Morne National Park, Canada
A long-term photographic study of Gros Morne National Park, Canada, reveals that most high-risk landslide sites along Western Brook Pond remain stable, while thin-skinned landslides near Winter House Brook have persisted for over a century. The research used repeated imagery to document landscape changes—such as stone rings, coastal dynamics, and river modifications—driven primarily by natural forces like gravity, precipitation, and frost heaving rather than human activity. This non-invasive method offers valuable insights into ecological integrity, public safety, and landscape processes, with minimal cost or environmental impact.
Leisure and the Net Opportunity Cost of Travel Time in Recreation Demand Analysis: An Application to Gros Morne National Park
Research reveals that visitors to Gros Morne National Park, a remote UNESCO World Heritage Site, value recreational access with a lower opportunity cost of travel time relative to their wage rate compared to previous studies. This finding challenges conventional assumptions by endogenously estimating the fraction of hourly earnings that best represents this cost, rather than imposing it exogenously. The study employs advanced count data models accounting for zero-truncation and overdispersion, providing a nuanced understanding of consumer surplus in park visitation. By linking visitor characteristics to opportunity costs, the research offers new insights into recreational demand analysis, particularly for remote sites.
Trichomycetes from Newfoundland, including Gros Morne National Park
Research in Gros Morne National Park, Newfoundland, has uncovered three new species of Trichomycetes fungi—Smittium colboi, Smittium georgense, and Stachylina forantipes—alongside six additional species representing new geographic records for the region. Notably, Spartiella barbata is reported in North America for the first time. The study analyzed aquatic insects from coastal sites across Newfoundland, revealing diverse fungal taxa with taxonomic significance, including detailed observations of Pennella hovassi. This work expands the known biodiversity of Trichomycetes in Atlantic Canada and provides critical insights into their ecological distribution.
