Vaccines are widely available in the US and Canada for walk-in service at medical providers and pharmacies. Many areas are still operating dedicated immunization clinics. Vaccines are safe and effective, including against the omicron variant of concern. Vaccines are now available for all age groups.
As of June 2022, travel restrictions have largely ended for travellers with up-to-date vaccinations. Be ready to show proof of vaccination when crossing national borders. Canada also requires use of the ArriveCAN app or website.
A lunar eclipse greeted early risers on 26 May 2021. Earth’s shadow totally covered the moon for a few minutes at about 1119 UT. This was about the time the moon was setting over North America, and was after sunrise in the far north of Alberta and Saskatchewan.
Montana Tech’s Robert Pál joined Huixuan Liao of Sun Yat-sen University and Manzoor Shah of the University of Kashmir on 9 February for a panel discussion on alpine botany, during the 2021 AAAS Annual Meeting.
Alpine environments are particularly fertile ground for climate change ecology because broad variation in microclimates can be found over a relatively short distance. As temperatures warm, new types of plants may rise above their former range. As moisture patterns change, areas may become better or worse for the growth of certain species. And lurking everywhere is the persistent threat of new and invasive species: non-native plants that spread and grow in manners that negatively impact the local environment, which may be hard to control once they take root.
The distinction between a fast-spreading non-invasive plant and an invasive species can be hard to pinpoint, but it often depends on whether it monopolizes an area at the expense of the broader ecosystem. Spotting them in the field can require a keen eye; certain invasive grasses can be notoriously hard to identify, even for experts.
When asked about ways invasive plants can be a solution, rather than a pest, Pál cited some concepts in harvesting invasive species as food, or to tap heavy metals out of toxic soils. Liao mentioned that some fast-growing plants can be used to combat coastal erosion.
When it came to encouraging new scientists, Shah said anyone can feel the excitement of a discovery on an ordinary walk, just by looking around their home turf for plants that look new or out of place, and taking samples to send in to the experts. Pál suggests that students looking to get into the field would benefit from learning the kinds of plants that help and harm their local environment, and further study in botany and ecology.
