Although jellyfish can be a nuisance and a hazard, they are an important component of marine ecosystems. Their lifecycle is fascinating, and their survival instinct is impressive. On this episode of Fish University, we’ll dive deep into the world of cnidarians with someone almost as...

info_outlineIn this episode, Stephanie Boyles-Griffin, Jessica Tegt, Steve Demarais, and Bronson Strickland discuss the complexities of urban deer management, exploring the challenges posed by growing deer populations in urban areas. While recreational hunting remains the most effective and practical tool for population control in most settings, an increasing number of circumstances—especially in urban and suburban areas—render it unfeasible. Stephanie and Jessica, both from the Botstiber Institute, outline non-lethal and alternative methods commonly used to manage deer in these environments and walk through the series of decisions required to evaluate which techniques are appropriate and how likely they are to succeed.
Below, Stephanie and Jessica have provided resources if you are interested in learning more.
