In this issue…

An eight year synthesis of our BioInvasions Records journal: patterns and trends in alien and cryptogenic species records.

A scholarly discussion on ballast water testing following an earlier publication in Management of Biological Invasions raises some important issues in experimental design and study replication. Hull and Linden comment on the paper and the authors (Molina et al.) reply to these comments in the same issue.

We all know that prevention is cheaper than the cure… but what principles apply in eradication economics for invasive alien aquatic plants?

A new surveillance list of 144 species informs Great Lakes managers about species that are not yet widespread but are predicted to cause impacts in the near future.

This study surveyed non-native small mammal species in the South African pet trade. Most traded species were the Norwegian rat, guinea pig, European rabbit and the house mouse.

Habitat suitability models can be useful for predicting biological invasions: here is an application for the spread of Miconia calvescens in the East Maui Watershed in Hawa’ii.

How much sampling is enough? This study developed a decision support tool to guide sampling design choices using the early detection monitoring of New Zealand mudsnail as a model example.

A Bug Alert and targeted trapping efforts did not find the invasive brown marmorated stink bug in Cyprus but will make early detection in the future more likely!

Live baitfish can introduce diseases or other non-target species into the environment. Visual inspection and advanced diagnostic tools help to better understand and manage this risk.

How should we prioritize management of non-native species in protected areas when information is scarce? This study proposes criteria and a checklist for plants and terrestrial vertebrates in eight protected areas on the Ecuadorian coast.

Reef Guardians in action: social media networks facilitate communication among local community groups in a grass-roots lionfish removal program in the British Virgin Islands.

Fish conundrum in Malaysia: this survey finds that members of the public have considerable knowledge of negative impacts of alien fish, however, these species are also economically important.

Freezing is an effective method to rid your nets or other equipment of faucet snails (Bithynia tentaculate). But be aware, wet gear needs longer freezing times than dry gear!

Brown tree snakes in Guam can grow very large, making regular baits less effective. This study published the first dose-response curve for this invasive vertebrate while another study tested physical barriers for invasive species control on Guam.

Water buffalos cause serious damage to floodplains in the Amazon. Aerial surveys reveal that populations remained stable but need to be monitored regularly to inform protected area management.
