Western North American Naturalist, formerly The Great Basin Naturalist, is a peer-reviewed scientific journal focusing on biodiversity and conservation of western North America. The journal's geographic coverage includes "from northernmost Canada and Alaska to southern Mexico, and from the Mississippi River to the Pacific Ocean."[2] Established in 1939, it is published by the Monte L. Bean Life Science Museum (Brigham Young University). The journal is published quarterly, with monographs published irregularly in Monographs of the Western North American Naturalist.[3]

Transcription
Blue whales [Balaenoptera musculus] are the biggest animals ever to exist on earth. They can weigh upwards of 150 tons, which is more than the largest dinosaurs! But the blue whale is not the biggest living thing. That title goes to.... well, it depends on what you mean by "biggest"! The tallest may be a redwood tree [Sequoia sempervirens] nicknamed "Hyperion" in California. At a towering 115M, this giant is taller than the statue of liberty [at 93M...show it's 25% taller]. The most extensive organism is a very old "humongous fungus" that covers a whopping 2,385 acres in a national forest in Oregon. At the base of the trees, bunches of "honey mushrooms" [Armillaria solidipes] appear... they are the "fruiting bodies" produced by the fungus, which otherwise lives out of sight - imagine if apple trees [Malus domestica] grew underground and only the apples were visible to us! That's basically what the fungus does, except that it spreads its "mycelia" not just through the soil but also through the roots and bark of trees in the forest, attacking them and stealing their nutrients so it can continue spreading outwards. However, if we're talking about the good old heaviest organism ever found, that prize goes to a giant panda [Ailuropoda melanoleuca] living high on a Utah plateau. Just kidding... It goes to a single quaking aspen [Populus tremuloides] named "Pando" that weighs over 6,000 tonnes - as much as forty blue whales. If you go to Fishlake National Forest, though, you won't see a giant tree trunk - you'll just see a forest of regular-sized trees. But, thanks to genetic testing, we've learned that this stand of aspen covering 106 acres of land is actually a single clonal organism that grew from a lone seed long ago. That single tree was able to spread so much because its roots send up shoots that grow into what look like individual trees. Since all 47,000 "trees" are part of the same organism, the forest behaves somewhat unusually, for example, the entire forest transitions simultaneously from winter to spring and uses its vast network of roots to distribute water and nutrients from trees with plenty to trees in need. Speaking of water... if you include water when weighing these giant organisms, then the humongous fungus might actually weigh more than Pando. But foresters, at least, care only about the mass actually produced during growth: the dry mass. And since fungi are mostly water Pando wins. Either way, it's likely that some of the belowground connections, whether roots or mycelia have become severed over time, meaning these giants are probably made up of smaller, but still ginormous and genetically identical, patches. And finally, because of the extensive testing required to confirm "biggest anything" claims, the fungus and aspen can only profess to be the largest living organisms ever found - there may be even bigger monsters lurking right under our feet, just waiting to be discovered!
History
Vasco M. Tanner founded the magazine after a term as editor at Proceedings magazine.[4] His hope for the journal was to have a publication that covered a wide range of biology-related topics in addition to having a place to publish his own research. From 1939 through 1966, the journal limited the publication of their issues to once or twice a year due to World War II.[5][6] Franklin Harris encouraged the journal to continue publication, and it was one of the first journals to be used "for exchange purposes" by university libraries.[5] From 1967 on, the journal published quarterly issues. Tanner served as editor of the Great Basin Naturalist until 1970.[4] Steven Wood, Tanner's successor as editor, established an editorial board for the journal. The board allowed for the journal to utilize an improved peer review process.[6]
In 1975, the journal moved its editorial offices to the Monte L. Bean Life Science Museum.[6] In 1976, articles too long for publication in the journal started being published in The Great Basin Naturalist Memoirs series.[7] In 1990, Jim Barnes succeeded Steven Wood as editor.[6] The journal's editor changed again in 1994 to Richard Baumann.[6] In 1999, the publication of The Great Basin Naturalist ended.[4] The journal's title changed to Western North American Naturalist, which started publishing in 2000.[8] In 2006, Mark C. Belk became the journal's new editor.[9][10] Belk was still the editor in 2017.[11]
