A recent trend in invasion ecology relates the success of non‐indigenous species (NIS) to
reduced control by enemies such as pathogens, parasites and predators (ie the enemy …

A predictive understanding of the ecological impacts of nonnative species has been slow to
develop, owing largely to an apparent dearth of clearly defined hypotheses and the lack of a …

The North American Great Lakes have been invaded and dramatically altered by more than
145 alien species. Many invasions have occurred during the past few decades because of …

Since 1900, 123 freshwater animal species have been recorded as extinct in North America.
Hundreds of additional species of fishes, mollusks, crayfishes, and amphibians are …

A widely cited hypothesis in ecology is that species-rich communities are less vulnerable to
invasion than species-poor ones, owing to competition for limiting resources (the "biotic …

The uniqueness of the current, global mass invasion by nonindigenous species has been
challenged recently by researchers who argue that modern rates and consequences of …

Although widely detected in marine ecosystems, microplastic pollution has only recently
been documented in freshwater environments, almost exclusively in surface waters. Here, we …

Non‐native species cause changes in the ecosystems to which they are introduced. These
changes, or some of them, are usually termed impacts; they can be manifold and potentially …

1. Freshwater mussels (Order Unionoida) are the most imperiled faunal group in North
America; 60% of described species are considered endangered or threatened, and 12% are …

Despite intensive research during the past decade on the effects of alien species, invasion
science still lacks the capacity to accurately predict the impacts of those species and, therefore…
