The staff and board of the North American Invasive Species Management Association review invasive species headlines each month. This helps us stay on top of trends and further our mission to support, promote, and empower invasive species prevention and management in North America. We then share invasive species news most relevant for people who manage terrestrial and aquatic invasive species across the the United States, Canada, Mexico and the world.

These distributional lists provide essential baseline information required prior to undertaking studies to introduce biological control agents of invasive pests that may have escaped their native, natural enemies when they arrived in North America.

The findings are important in the context of coastal vulnerability to the effects of climate change, including increasing danger from flooding and erosion from storms and rising water.

The team studied open source and peer-reviewed literature on species that were not native to the continent but had caused crop losses to assess the economic impact on yield, management and the cost of research.

An investigation by an international team of scientists, including the University of Leeds’ School of Biology, says the emergence of human diseases share many of the same challenges as species invasions and that studying them together could provide solutions.

Clavelina oblonga, an invasive marine fouling species, not only reduces diversity in communities it invades, it also interferes in their recovery following natural disasters—a process known as “succession.”
Detection, Management and Control

As a research team from UC Davis discovered, invasive species don’t go quietly. Nor do they react well to full-on assaults. In fact, years of digilent and costly crab removal from a Bay Area lagoon went terribly wrong, triggering an unexpected population explosion.

This excerpt from a new book describes how the invaders may be contributing to the decline of native Chilean bumblebee species, through competition and, perhaps, through diseases they carry to which native bumblebees have little or no resistance.
