Invasive species remain a major environmental problem in the world's oceans. Managing vectors of introduction is most effective means mitigating this problem, but current risk assessments and management strategies are largely focused on species, not certainly multiple simultaneous vectors. To highlight issue that contribute to invasions, we analyzed historical contemporary contributions eight maritime establishment nonindigenous California, where were associated with two six Vessel...
Abstract Aim Topographic complexity is widely accepted as a key driver of biodiversity, but at the patch‐scale, complexity–biodiversity relationships may vary spatially and temporally according to environmental stressors mitigates, species richness identity potential colonists. Using manipulative experiment, we assessed spatial variation in patch‐scale effects on intertidal biodiversity. Location 27 sites within 14 estuaries/bays distributed globally. Time period 2015–2017. Major taxa...
Forecasting assemblage-level responses to climate change remains one of the greatest challenges in global ecology [1, 2]. Data from marine realm are limited because they largely come experiments using numbers species [3], mesocosms whose interior conditions unnatural [4], and long-term correlation studies based on historical collections [5]. We describe first ever experiment warm benthic assemblages ecologically relevant levels situ. Heated settlement panels were used create three test...
Early naturalists suggested that predation intensity increases toward the tropics, affecting fundamental ecological and evolutionary processes by latitude, but empirical support is still limited. Several studies have measured consumption rates across latitude at large scales, with variable results. Moreover, how affects prey community composition such geographic scales remains unknown. Using standardized experiments spanned 115° of 36 nearshore sites along both coasts Americas, we found...
Significance Theoretical models of population dynamics have shown the counterintuitive conclusion that harvest can increase equilibrium size a population. These increases in response to mortality been considered for fisheries and removal non-native species be driven by density-dependent overcompensation. This is first controlled experimental field demonstration showing harvest-driven overcompensation produced 30-fold, single-year abundance invasive European green crab ( Carcinus maenas ),...
Experimental studies evaluating the effects of food availability on movement free-ranging animals generally involve supplementation rather than suppression.Both approaches can yield similar insights, but we were interested in potential for using suppression management and control invasive predators, particular, brown treesnake (Boiga irregularis) Guam.However, understanding a species' response to resources is critical before employing such strategy.We studied movements 24 radio-tagged B....
In August 2006, the ten largest marinas in Scotland were surveyed for presence of seven non-native species, known to occur at other locations within UK: crustaceans Caprella mutica and Eriocheir sinensis, ascidians Perophora japonica Styela clava, green alga Codium fragile subsp. tomentosoides, brown algae Sargassum muticum Undaria pinnatifida. A variety structures, including pontoon floats, chains harbour walls inspected a depth 0.5 m these species. Seven had one or more target C. was found...
Coastal regions exhibit strong geographic patterns of nonnative species richness. Most invasions in marine ecosystems are known from bays and estuaries, where ship-mediated transfers (on hulls or ballasted materials) have been a dominant vector introductions. Conspicuous spatial differences richness exist among bays, but the quantitative relationship between invasion magnitude shipping activity across sites is largely unexplored. Using data on (for invertebrates algae) commercial 16 large...
Abstract Few reports exist that describe marine non‐native species in the Southern Ocean and near‐shore waters around Antarctic continent. Nevertheless, Antarctica's isolated communities, which show high levels of endemism, may be vulnerable to invasion by anthropogenically introduced from outside Antarctica via vessel hull biofouling. Hull surveys British Survey's RRS James Clark Ross were undertaken between 2007 2014 at Rothera Research Station on Peninsula (Lat. 67°34'S; Long. 68°07'W)...
Marine soft sediments are some of the most widespread habitats in ocean, playing a vital role global carbon cycling, but amongst least studied with regard to species composition and ecosystem functioning. This is particularly true Polar Regions, which currently undergoing rapid climate change, impacts poorly understood. Compared other latitudes, sediment also experience additional environmental drivers strong seasonality intense disturbance from iceberg scouring, major structural forces for...
To determine the importance of recreational boating as a vector for distributing marine organisms, including non-native species, extent hull fouling species on yachts in Scotland was assessed. In August 2006, up to 100 each ten largest marinas were ranked using index. 23 yacht owners asked questionnaire general characteristics and its travel history relation level fouling. 59 % surveyed found have macrofouling attached their hulls, suggesting that has high potential throughout Scotland....
Abstract Caprella mutica (Crustacea, Amphipoda) has been widely introduced to non‐native regions in the last 40 years. Its native habitat is sub‐boreal northeast Asia, but Northern Hemisphere, it now found on both coasts of North America, and Atlantic coastlines Europe. Direct sequencing mitochondrial DNA (cytochrome c oxidase subunit I gene) was used compare genetic variation populations C. . These data were investigate invasion history test potential source Japan. High diversity (31...
The amphipod Caprella mutica is one of the most rapidly invading species in Europe and has extended its range throughout North Sea Celtic coasts English Channel less than fourteen years.It was first described from sub-boreal areas north-east Asia 1935 since spread to both northern southern hemispheres.The European record Netherlands 1994.Since then it within later west coast Scotland Ireland.C. frequently associated with man-made structures found abundance on boat hulls, navigation/ offshore...
Abstract Marine encrusting communities play vital roles in benthic ecosystems and have major economic implications with regards to biofouling. However, their ability persist under projected warming scenarios remains poorly understood is difficult study realistic conditions. Here, using heated settlement panel technologies, we show that after 18 months Antarctic do not acclimate either +1 °C or +2 above ambient temperatures. There significant up-regulation of the cellular stress response...
Biofouling accumulation on ships' submerged surfaces typically occurs during stationary periods that render more susceptible to colonization than when underway. As a result, longer typical port residence times (hours days), often referred as lay-ups, can have deleterious effects hull maintenance strategies, which aim minimize biofouling impacts ship operations and the likelihood of invasive species transfers. This experimental study tested different lay-up durations magnitude biofouling,...
Abstract Aim The movement of biofouling organisms by ships results in the transfer marine species across biogeographical boundaries on a global scale. We used barnacles, relatively well‐studied taxon, to investigate extent which modern commercial vessels disperse beyond their current known ranges. Location Vessels predominantly operated North Pacific; sampling was conducted Los Angeles (CA), Portland (OR), Ketchikan (AK) and Apra Harbor (GU). Methods Barnacles were collected from submerged...
