Catastrophes, connectivity and Allee effects in the design of marine reserve networks

Easton White, Marissa Baskett & Alan Hastings
Catastrophic events, like oil spills and hurricanes, occur in many marine systems. One potential role of marine reserves is buffering populations against disturbances, including the potential for disturbance-driven population collapses under Allee effects. This buffering capacity depends on reserves in a network providing rescue effects, setting up a trade-off where reserves need to be connected to facilitate rescue, but also distributed in space to prevent simultaneous extinction. We use a set of population models to...

Data for: Long-term surveys support declines in early-season forest plants used by bumble bees

John Mola, Leif Richardson, Greg Spyreas, David Zaya & Ian Pearse
Populations of bumble bees and other pollinators have declined over the past several decades due to numerous threats, including habitat loss and degradation. However, we can rarely investigate the role of resource loss due to a lack of detailed long-term records of forage plants and habitats. We use 22-year repeated surveys of more than 262 sites located in grassland, forest, and wetland habitats across Illinois, USA to explore how the abundance and richness of bumble...
