What these salamanders could tell us about the health of Nova Scotian forests The eastern red-backed salamander may hold the key to better understanding the health of old hemlock forests in southwestern Nova Scotia. Researchers are looking at salamander populations and behaviour to study the impacts of an invasive bug and the insecticides we use to fight it. https://www.cbc.ca/news/canada/nova-scotia/salamander-insecticide-hwa-impacts-9.7302030?cmp=rss

RE: https://dice.camp/@Da_Gut/116842635266307459 This podcast episode is crackling good. That unisexual salamander complex is absolutely crazy. It uses the sperm of five different species of salamander to trigger its egg production. It’s a polyploidy complex - well, the majority are a tetraploidy. The unisex lineage has been around for over 2 million years. The bit on dragonfly migration is equally fascinating #Nature #Salamanders #Dragonflies #Podcast
