Conservation challenges and opportunities for native apple (Malus) species in Canada

PLANTS, PEOPLE, PLANET, EarlyView.
Apple, one of the world's most widely cultivated and economically important fruit crops, has two wild relatives native to Canada. In this review, we describe the importance of these native apple species to Indigenous heritage and the current threats the species faces due to pests, diseases, and habitat loss.

Hydropower Effluent as a Marine Pollutant; Impacts of River Regulation on Estuarine and Coastal Ecology

River Research and Applications, EarlyView.
ABSTRACT The confluence of rivers with the ocean creates biological hotspots where temperature, salinity, and nutrients mix to provide excellent conditions for rearing, growth, and refuge to a multitude of organisms. Worldwide, estuaries are highly productive and biodiverse.

Automated extraction of right whale morphometric data from drone aerial photographs

Remote Sensing in Ecology and Conservation, EarlyView.
Aerial photogrammetry is a popular non‐invasive method for measuring marine mammal body size, body morphometrics, and body condition, but processing large datasets efficiently remains challenging. We developed a machine learning algorithm using Mask R‐CNN models to automatically measure body morphometrics of southern right whales from aerial ...

Drone photogrammetry reveals contrasting body conditions of dugongs across the Indo‐Pacific

Remote Sensing in Ecology and Conservation, EarlyView.
The monitoring of body condition has gained traction as a way to provide early warning signals of population decline, prompting conservation actions. However, the environmental and anthropogenic drivers of body condition variations are rarely investigated.
