It is unclear whether transport by human vectors can increase the robustness of translocated populations and thereby enhance their invasiveness. To test this concept, we investigated the effect of heat stress on the tolerance of mussel populations towards a second stress event of the same kind. The heat challenges we mimicked can be faced by marine invertebrates that are transported through regions with high sea surface temperatures on ship hulls or in ballast water tanks. The study included 5… Expand

Figures and Tables from this paper

Plasticity in thermal hardening of the invasive Asian house gecko
It was found that basal heat tolerances did not differ between populations, but geckos from Australia had lower cold tolerance than gecko from Thailand, and the introduced gecko had a higher magnitude of cold hardening. Expand
Season-dependent effects of ocean warming on the physiological performance of a native and a non-native sea anemone
Results show that the non-native species may have a broader thermal tolerance than the native taxonomically related species, but the latter displays behavioral adaptations to avoid adverse conditions of high temperatures. Expand
Nutritional vulnerability of early zoeal stages of the invasive shrimp Lysmata vittata (Decapoda: Caridea) in the Atlantic Ocean
The nutritional vulnerability index (PRS50/PNR50 = 0.54) indicates that L. vittata presents intermediate dependence on exogenous food during the early larval stages, which might help the understanding of the invasive potential of this species in the Atlantic Ocean. Expand
Northward establishment of the mediterranean mussel Mytilus galloprovincialis limited by changing climate
The findings of this study indicated that M. edulis was consistently the most abundant species, followed by hybrids and M. galloprovincialis, however, nearshore meteorological extremes may have an impact in its larval settlement, establishment and subsequent reproductive output. Expand
Sexual system, reproductive cycle and embryonic development of the red-striped shrimp Lysmata vittata, an invader in the western Atlantic Ocean
Evidence is provided that the invasive shrimp L. vittata has reproductive and embryonic developmental characteristics that may be favorable to the establishment of populations during invasive processes, and important insights into the biology of invasion are provided. Expand
Nutritional Dimensions of Invasive Success.
This work discusses the power of nutrition to achieve a more predictive invasion biology that explicitly integrates physiological mechanisms, and reviews recent advances and synthesizes NG predictions about behavioral traits that favor invasive establishment, and evolutionary dynamics that promote invasive spread.

Revue systématique de la littérature relative aux facteurs de risque de mortalité des moules exploitées en France - Rapport du Conseil scientifique et technique du programme de recherche en santé des coquillages : étude éco-épidémiologique
La recherche bibliographique maximalisee realisee dans le cadre de cette revue systematique de la litterature a permis de decrire le paysage de la connaissance existante sur les facteurs de risque deExpand
A trampoline effect occurring in the stages of planetary reseeding
It is possible that life has been, and still is, transported between the worlds of the solar system, owing to impacts leading material away from the impact region, in the so-called lithopanspermia theory. Expand


Habitat degradation correlates with tolerance to climate-change related stressors in the green mussel Perna viridis from West Java, Indonesia.
Mussels from the eutrophied and polluted Jakarta Bay showed a significantly smaller deviation from their normal oxygen consumption and higher survival rates when stressed than their conspecifics from the unaffected Lada Bay, showing that human induced habitat degradation correlates with mussel tolerance to environmental stress.

Heat Stress in the Intertidal: Comparing Survival and Growth of an Invasive and Native Mussel Under a Variety of Thermal Conditions
The physiological effects of thermal stress in both low tide and high tide conditions are compared between Mytilus galloprovincialis, a worldwide mussel invader, and M. trossulus, a sibling species and results suggest that as climates shift due to global warming, the temperatures favorable to M. gallopovincialis will become more common. Expand
Food availability in an anthropogenically impacted habitat determines tolerance to hypoxia in the Asian green mussel Perna viridis
It is explained why phenotypic plasticity and high BCIs are more likely the causes of population-specific differences in hypoxia tolerance in P. viridis than stress-induced selection for robust genotypes. Expand
Nutritional status affects the capacity of the snail Concholepas concholepas to synthesize Hsp70 when exposed to stressors associated with tidal regimes in the intertidal zone
The synthesis of Hsp70 for the juveniles of this intertidal snail species was coordinated and adapted to the tidal cycle, and the species responds in a similar way to hot and cold emersion conditions. Expand
Temperature Tolerance and Stress Proteins as Mechanisms of Invasive Species Success
Empirical data from a marine community is used as a case study to address the hypotheses that (1) geographic temperature range attributes are related to temperature tolerance, leading to greater eurythermality in invasive species, and (2) stress protein expression is a subcellular mechanism that could contribute to differences in thermotolerance.

Do invaders always perform better? Comparing the response of native and invasive shrimps to temperature and salinity gradients in south-west Spain
It was found that the invasive species was the most tolerant to rapid increase in temperature, and consistently consumed less oxygen over a broad range of temperatures and salinities, suggesting that climate change will increase the success of invaders. Expand
Differences in stress tolerance and brood size between a non-indigenous and an indigenous gammarid in the northern Baltic Sea
There are clear competitive advantages for the non-indigenous G. tigrinus compared to the indigenous G. zaddachi, and these may be further strengthened through ongoing environmental changes related to increased eutrophication and a warming climate in the Baltic Sea region. Expand
Stress resistance in two colonial ascidians from the Irish Sea: the recent invader Didemnum vexillum is more tolerant to low salinity than the cosmopolitan Diplosoma listerianum
The recent invader Didemnum vexillum, which recently invaded the Irish Sea, is more tolerant to fluctuations in salinity than the closely related Diplosoma listerianum, a cosmopolitan species of wide ranging distribution, and this competitive advantage may facilitate the establishment and spread of D. vexillums.

Drought acclimation confers cold tolerance in the soil collembolan Folsomia candida.
Evidence is provided that the stresses exerted by desiccation and cold at the cellular level have sufficient similarities to induce overlapping adaptations and are likely to contribute to the observed cross-tolerance. Expand
Dynamics of heat‐induced thermal stress resistance and hsp70 expression in the springtail, Orchesella cincta
A strong correlation between Hsp70 expression levels and thermal resistance following a heat hardening treatment is supported and it is shown that gene and protein expression follow different dynamics, a difference that may be important for the understanding of the role of candidate genes in functional studies.
