Survival Against the Odds: Alberta’s Half-moon Hairstreak Butterfly

By Steph Weizenbach / 29 September 2023

BY BENNY ACORN

Waterton Lakes National Park is truly one of the most remarkable areas in all of Alberta, where natural beauty is partnered with rich and unique biological diversity. Although you would not expect it, the story of one of Alberta’s rarest insects begins here, under the late-winter snow. This is a story of unexpected alliances, remarkable specialization, and perseverance in the face of catastrophic adversity, and it all takes place on the Blakiston Fan.

Spiders: The Misunderstood Jewels of Alberta’s Biodiversity

By Steph Weizenbach / 7 July 2023

BY JAIME PINZON
Alberta is home to 628 species of spiders, representing almost half of those recorded in Canada. That’s more than the number of bird species we have in the province. Despite this great diversity, you are unlikely to encounter more than a small fraction of these species because many of them are either too small, have cryptic behaviours, or live in remote habitats.

Butterflies for Beginners

By Nature Kids / 11 April 2023

BY NICK CARTER

My experience is that once you’ve been bitten by the entomology bug, you won’t look back. A good place to start, if you are keen to expand your biodiversity horizons, is butterflies. Butterflies provide a good introduction to the world of insects for a variety of reasons. Many species are bright, colourful, and not too hard to find.

The 20,000-Year-Old Story of the Golden-Crowned Kinglet

By Nature Kids / 11 April 2023

BY DANIKA SCHRAMM

The last Ice Age had an enormous impact on Canadian species, in some cases creating genetically distinct populations. To illustrate how geneticists have arrived at these conclusions, I’m going to walk through a real-world example from my own research on golden-crowned kinglets, one of North America’s smallest passerines.

Deadly Fungus Adds to Bat Conservation Concerns

By Nature Kids / 11 April 2023

BY CORY OLSON

While bats have a remarkable ability to manage energy reserves, only a few can withstand the devastating impacts of white-nose syndrome (WNS), a disease caused by a fungus, Pseudogymnoascus destructans, that grows on bats during hibernation, which will lead to more frequent arousals during the winter, depletion of energy stores, and eventual starvation.

Delta Dawn with the Wolves of Wood Buffalo National Park

By Rick Schneider / 13 January 2023

BY ERIN MCCLOSKEY

Wood Buffalo National Park was established in 1922 to protect what remained of Canada’s wood bison. Today, exactly 100 years later, the park supports a population of approximately 3,000 bison, which coexist alongside their natural predator, the wolf. The core range of the park is quite possibly the only place where bison are wolves’ primary prey.
