Abstract: Since 1900, 123 freshwater animal species have been recorded as extinct in North America. Hundreds of additional fishes, mollusks, crayfishes, and amphibians are considered imperiled. Using an exponential decay model, we derived recent future extinction rates for American fauna that five times higher than those terrestrial fauna. Assuming imperiled will not survive throughout the next century, our model projects a rate 4% per decade, which suggests America's temperate ecosystems...
Abstract 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 (i.e. enemy release hypothesis, ERH). Despite demonstrated importance host population dynamics, studies ERH are split – biogeographical analyses primarily show a reduction diversity introduced range compared with native range, while community imply that NIS no less affected than invaded community. broad review literature...
Species moved by human activities beyond the limits of their native geographic ranges into areas in which they do not naturally occur (termed aliens) can cause a broad range significant changes to recipient ecosystems; however, impacts vary greatly across species and ecosystems are introduced. There is therefore critical need for standardised method evaluate, compare, eventually predict magnitudes these different impacts. Here, we propose straightforward system classifying alien according...
A predictive understanding of the ecological impacts nonnative species has been slow to develop, owing largely an apparent dearth clearly defined hypotheses and lack a broad theoretical framework. The context dependency impact fueled perception that meaningful generalizations are nonexistent. Here, we identified reviewed 19 testable explain temporal spatial variation in impact. Despite poor validation most date, evidence suggests each can at least some situations. Several scope (applying...
Although widely detected in marine ecosystems, microplastic pollution has only recently been documented freshwater environments, almost exclusively surface waters. Here, we report microplastics (polyethylene microbeads, 0.40–2.16 mm diameter) the sediments of St. Lawrence River. We sampled 10 sites along a 320 km section from Lake Francis to Québec City by passing sediment collected benthic grab through 500 μm sieve. Microbeads were discovered throughout this section, and their abundances...
A widely cited hypothesis in ecology is that species-rich communities are less vulnerable to invasion than species-poor ones, owing competition for limiting resources (the "biotic resistance" model). However, evidence biotic resistance aquatic ecosystems equivocal. Contrary the view become more resistant as they accumulate species, rate of has increased over past century areas have received frequent shipping traffic. Furthermore, introduced species may facilitate, rather compete with, one...
Abstract: The uniqueness of the current, global mass invasion by nonindigenous species has been challenged recently researchers who argue that modern rates and consequences establishment are comparable to episodes in geological past. Although there is a fossil record invasions occurring waves after geographic barriers had lifted, such episodic events differ markedly from human‐assisted spatial temporal scales number diversity organisms involved long‐distance dispersal. Today, every region...
The identification and risk assessment of potential biological invaders would provide valuable criteria for the allocation resources toward detection control invasion threats. Yet, freshwater biologists have made few attempts at predicting invaders, apparently because such efforts are perceived to be costly futile. We describe some simple, low-cost empirical approaches that facilitate prediction demonstrate their use in identifying high-risk species from an important donor region:...
1. Freshwater mussels (Order Unionoida) are the most imperiled faunal group in North America; 60% of described species considered endangered or threatened, and 12% presumed extinct. Widespread habitat degradation (including pollution, siltation, river channelization impoundment) has been primary cause extinction during this century, but a new stress was added last decade by introduction Eurasian zebra mussel, Dreissena polymorpha , biofouling organism that smothers shells other molluscs...
Abstract Non‐native species cause changes in the ecosystems to which they are introduced. These changes, or some of them, usually termed impacts; can be manifold and potentially damaging biodiversity. However, impacts most non‐native poorly understood, a synthesis available information is being hindered because authors often do not clearly define impact. We argue that explicitly defining impact will promote progress toward better understanding implications biodiversity caused by species;...
ABSTRACT The Laurentian Great Lakes basin has been invaded by at least 182 non‐indigenous species. A new invader is discovered every 28 weeks, which the highest rate recorded for a freshwater ecosystem. Over past century, invasions have occurred in phases linked to changes dominant vectors. number of ship‐vectored invaders per decade correlated with intensity vessel traffic within basin. Ballast water release from ocean vessels putative vector 65% all since opening St. Lawrence Seaway 1959....
Despite intensive research during the past decade on effects of alien species, invasion science still lacks capacity to accurately predict impacts those species and, therefore, provide timely advice managers where limited resources should be allocated. This has been partly by context-dependent nature ecological impacts, highly skewed toward certain taxa and habitat types, lack standardized methods for detecting quantifying impacts. We review different strategies, including specific...
Globally, Invasive Alien Species (IAS) are considered to be one of the major threats native biodiversity, with World Conservation Union (IUCN) citing their impacts as 'immense, insidious, and usually irreversible'.It is estimated that 11% c. 12,000 alien species in Europe invasive, causing environmental, economic social damage; it reasonable expect rate biological invasions into will increase coming years.In order assess current position regarding IAS determine issues were deemed most...
Abstract Invasion ecology urgently requires predictive methodologies that can forecast the ecological impacts of existing, emerging and potential invasive species. We argue many ecologically damaging invaders are characterised by their more efficient use resources. Consequently, comparison classical ‘functional response’ (relationship between resource availability) trophically analogous native species may allow prediction invader impact. review utility trait comparisons history context...
Since its emergence in the mid-20th century, invasion biology has matured into a productive research field addressing questions of fundamental and applied importance. Not only number empirical studies increased through time, but also competing, overlapping and, some cases, contradictory hypotheses about biological invasions. To make these contradictions redundancies explicit, to gain insight field's current theoretical structure, we developed Delphi approach create consensus network 39...
Summary Predictions of the identities and ecological impacts invasive alien species are critical for risk assessment, but presently we lack universal standardized metrics that reliably predict likelihood degree impact such invaders (i.e. measurable changes in populations affected species). This need is especially pressing emerging potential future have no invasion history. Such a metric would also ideally apply across diverse taxonomic trophic groups. We derive new invader blends: (i)...
Unprecedented rates of introduction and spread non-native species pose burgeoning challenges to biodiversity, natural resource management, regional economies, human health. Current biosecurity efforts are failing keep pace with globalization, revealing critical gaps in our understanding response invasions. Here, we identify four priority areas advance invasion science the face rapid global environmental change. First, should strive develop a more comprehensive framework for predicting how...
Natural hazards — such as storms, floods, and wildfires can be disastrous phenomena so biological invasions, for which impacts are often irrevocable insidious. Yet, invasion awareness remains low compared to natural hazards, investments manage invasions remain vastly underfunded delayed. Here, we quantified costs relative raise political leverage. Analysing damage cost data over 1980–2019, economic losses from were of similar magnitude (e.g., $1,208.0 bn against $1,913.6 storms $1,139.4...
ABSTRACT Standardised terminology in science is important for clarity of interpretation and communication. In invasion – a dynamic rapidly evolving discipline the proliferation technical has lacked standardised framework its development. The result convoluted inconsistent usage terminology, with various discrepancies descriptions damage interventions. A therefore needed clear, universally applicable, consistent to promote more effective communication across researchers, stakeholders,...
