Comparison of specimen and image-based morphometrics in Cisco

Morphometric data from fish are typically generated using one of two methods: from direct measurements made on a specimen, or by extracting distances from a digital picture. We compared data on twelve morphometrics collected with these two different methods on the same collection of Cisco Coregonus artedi to assess the degree of bias in...

Elucidating controls on cyanobacteria bloom timing and intensity via Bayesian mechanistic modeling

The adverse impacts of harmful algal blooms (HABs) are increasing worldwide. Lake Erie is a North American Great Lake highly affected by cultural eutrophication and summer cyanobacterial HABs. While phosphorus loading is a known driver of bloom size, more nuanced yet crucial questions remain. For example, it is unclear what mechanisms are...
