Resilient structure of nature-based extension programs facilitates transition to online delivery and maintains participant satisfaction.

Restrictions on public gatherings in early 2020 due to the COVID-19 pandemic resulted in cancelation of in-person outreach programs offered by the Florida Master Naturalist Program and Natural Areas Training Academy, two successful University of Florida extension programs that provide natural history and resource management training to lay and professional audiences. In response, both programs rapidly transitioned to blended or 100% online educational methods to continue offering courses and maintain program operations. To assess participant responses to these changes, we used surveys and course registry data to evaluate and compare course enrollment, satisfaction, and outcomes among courses with new online formats to courses offered prior to the COVID-19 pandemic.

A Conservation-Based Approach to Compensation for Livestock Depredation: The Florida Panther Case Study.

Calf (Bos taurus) depredation by the federally endangered Florida panther (Puma concolor coryi) on ranches in southwest Florida is an important issue because ranches represent mixed landscapes that provide habitat critical to panther recovery. The objectives of this study were to (1) quantify calf depredation by panthers on two ranches in southwest Florida, and (2) develop a habitat suitability model to evaluate the quality of panther hunting habitat on ranchlands, assess whether the model could predict predation risk to calves, and discuss its potential to be incorporated into an incentive-based compensation program. We ear-tagged 409 calves with VHF transmitters on two ranches during 2011-2013 to document calf mortality.

Priorities for improving the scientific foundation of conservation policy in North America.

The Society for Conservation Biology (SCB) can enhance conservation of biodiversity in North America by increasing its engagement in public policy. Toward this end, the North America Section of SCB is establishing partnerships with other professional organizations in order to speak more powerfully to decision makers and taking other actions--such as increasing interaction with chapters--geared to engage members more substantively in science-policy issues. Additionally, the section is developing a North American Biodiversity Blueprint, which spans the continental United States and Canada and is informed by natural and social science.

Reconciling competing ecological explanations for sexual segregation in ungulates.

Sexual segregation in ungulates has important conservation and theoretical implications, but despite numerous studies, the impetus for this behavioral pattern remains a topic of debate. Sexual segregation hypotheses can be broadly grouped into social and ecological explanations, but only ecological explanations can adequately describe why sexes use different areas and habitats. The reproductive strategy hypothesis (RSH) and forage selection hypothesis (FSH) are leading ecological explanations, and although both have received support in the literature, neither the collective basis for that support nor overlap between these hypotheses has been adequately evaluated.
