Will climate change promote future invasions?
TLDR
Using ensemble forecasts from species distribution models to project future suitable areas of the 100 of the world's worst invasive species, it is shown that both climate and land use changes will likely cause drastic species range shifts.

virtualspecies, an R package to generate virtual species distributions
TLDR
This package combines the existing methodological approaches with the objective of generating virtual species distributions with increased ecological realism, and is designed to be extremely flexible to allow users to simulate their own defined species–environment relationships.

Massive yet grossly underestimated global costs of invasive insects
TLDR
A comprehensive database of economic costs of invasive insects is compiled, finding that invasive insects cost a minimum of US$70.0 billion per year globally, while associated health costs exceed US$6.9bn per year.

Without quality presence–absence data, discrimination metrics such as TSS can be misleading measures of model performance
TLDR
This work investigates TSS and an alternative set of metrics—similarity indices, also known as F‐measures, and shows that even in ideal conditions, TSS can be misleading because of its dependence on prevalence, whereas similarity/F‐measures provide adequate estimations of model discrimination capacity.

High and rising economic costs of biological invasions worldwide.
TLDR
The total reported costs of invasions reached a minimum of US$1.288 trillion over the past few decades (1970-2017), with an annual mean cost of US $26.8 billion, and these costs remain strongly underestimated and do not show any sign of slowing down, exhibiting a consistent threefold increase per decade.

Insights from modeling studies on how climate change affects invasive alien species geography
TLDR
A systematic review of 423 modeling case studies included in 71 publications that have examined the predicted effects of climate change on invasive alien species found for the plants and vertebrates studied that climate change will more frequently contribute to a decrease in species range size than an increase in the overall area occupied.

Structural bias in aggregated species‐level variables driven by repeated species co‐occurrences: a pervasive problem in community and assemblage data
Species attributes are often used to explain diversity patterns across assemblages/communities. However, repeated species co‐occurrences can generate spatial pattern and strong statistical…
