If downloading from my website for free, please consider making a donation here on BMC or via Venmo (@seanedge) - these pages take a long time to design! They are a source of income during this pandemic. Any contribution helps. My goal is to increase scientific literacy and foster an engaging connection to nature from the comforts of your own home. Please be safe and take care. All the best, Sean Vidal Edgerton (@thePenAndThePangolin)
