Aquatic Invasive Species Surveys of Pacificorp’s North Umpqua River Impoundments [PDF]

open access: yes, 2013
Ten North Umpqua Hydroelectric Project impoundments were surveyed for aquatic invasive species during the summer of 2012. One non-native submersed aquatic vegetation species (Potamogeton crispus) and one non-native snail species (Radix auricularia) was ...

Distributions of non‐native and native plants are not determined by the same environmental factors

open access: yesEcological Solutions and Evidence
Global environmental change will cause shifts in species communities, with non‐native species likely replacing native ones at an unprecedented rate. This will have consequences for biodiversity and ecosystem services, in addition to the ecological and ...

Competitive superiority of non-native invaders becomes weaker when plant diversity increases – a case study with Solidago species [PDF]

open access: yesNeoBiota
Two popular hypotheses in invasion biology are the “inherent superiority hypothesis”, stating that non-native species generally perform better than native species, and the “biotic resistance hypothesis”, stating that at local scale invasibility decreases

Current and potential distributions of three non-native invasive plants in the contiguous USA [PDF]

open access: yes, 2009
Biological invasions pose a serious threat to biodiversity, but monitoring for invasive species is time consuming and costly. Understanding where species have the potential to invade enables land managers to focus monitoring efforts.

Report on the 2013 Rapid Assessment Survey of Marine Species at New England Bays and Harbors [PDF]

open access: yes, 2014
Introduced species (i.e., non-native species that have become established in a new location) have increasingly been recognized as a concern as they have become more prevalent in marine and terrestrial environments (Mooney and Cleland 2001; Simberloff et ...

Clarifying the presence of Pseudosuccinea columella (Say, 1817) (Gastropoda: Hygrophila: Lymnaeidae) in Serbia [PDF]

open access: yesMalacologica Bohemoslovaca
We report the first record of Pseudosuccinea columella (Say, 1817) from Serbia. This finding in the Tamiš River clarifies its presence in Serbia which was questioned in the 2021 checklist, as it was previously confused with succineid gastropods.
