“…This is because introduced freshwater crayfish often exhibit invasive behavior in their non-native ranges [49]. As the number of NICS gradually increases in the European continent, and their ranges expand, new sympatric populations steadily appear [34,40,50]. Unlike between native and invasive crayfish species, the interactions between NICS when these co-occur are not yet well understood.…”

“…However, the red swamp crayfish seems superior, primarily owing to its greater growth rates and size achieved at adulthood. Recent research suggests a superior position of the red swamp crayfish at sympatric localities [34] as well as enhanced predation on the marbled crayfish [40].…”

“…As the number of NICS and their ranges expand, novel assemblages containing multiple NICS gradually occur [34,36,37]. However, studies simultaneously comparing life-history trait differences and possible interactions among multiple NICS are particularly limited [30,[38][39][40]. Among newly appearing species, the parthenogenetic marbled crayfish P. virginalis has become particularly widespread and concerning due to its reproduction strategy when theoretically even a single individual can establish a new population [37,41].…”

Biological invasions are increasingly recognized ecological and economic threats to biodiversity and are projected to increase in the future. Introduced freshwater crayfish in particular are protruding invaders, exerting tremendous impacts on native biodiversity and ecosystem functioning, as exemplified by the North American spiny-cheek, signal and red swamp crayfish as well as the Australian common yabby. The marbled crayfish is among the most outstanding freshwater crayfish invaders due to its parthenogenetic reproduction combined with early maturation and high fecundity. As their introduced ranges expand, their sympatric populations become more frequent. The question of which species and under what circumstances will dominate in their introduced communities is of great interest to biodiversity conservation as it can offer valuable insights for understanding and prioritization of management efforts. In order to examine which of the aforementioned species may be more successful as an invader, we conducted a set of independent trials evaluating survival, growth, claw injury, and reproduction using single-species stocks (intraspecific interactions) and mixed stocks (interspecific interactions) of marbled crayfish vs. other crayfish invaders since the onset of exogenous feeding. In both single and mixed stocks, red swamp crayfish and yabby grew faster than marbled crayfish, while marbled crayfish were superior to both spiny-cheek and signal crayfish in terms of growth. With the exception of signal crayfish, the faster-growing species consistently reached a higher survival rate. The faster-growing species tended to negatively impair smaller counterparts by greater claw injury, delayed maturation, and reduced fecundity. Only marbled crayfish laid eggs as early as 14 weeks in this study, which is earlier than previously reported in the literature. Thus, the success of marbled crayfish among invasive crayfish is significantly driven by relatively fast growth as well as an early and frequent reproduction. These results shed light on how interactions between invasive populations can unfold when their expansion ranges overlap in the wild, thereby contributing to the knowledge base on the complex population dynamics between existing and emerging invasive species.

“…Veselý et al. (2021) recently demonstrated that these two species had distinctive trophic niches, with P. clarkii constraining the trophic niche of F. limosus when co‐occurring. The high invasiveness potential of P. clarkii might be attributable to its ability to disperse overland (Cruz & Rebelo, 2007; Kerby et al., 2005; Thomas et al., 2019) and to its important agonistic behaviour (Gherardi & Cioni, 2004).…”

Patterns and determinants of phenotypic variability within two invasive crayfish species

Knowledge on the ecological determinants and evolutionary processes shaping intraspecific variability in the wild remains scarce. It is particularly needed in the context of biological invasions to fully understand the consequences of invasive species on the functioning of recipient ecosystems. Using geometric morphometrics, stable isotopes, and elemental composition analyses, we quantified phenotypic variability (morphological, trophic, and stoichiometric traits) within and among invasive populations of two crayfish species with distinct invasion histories over 23 gravel pit lakes in southwest France. We sampled 12 populations of the red swamp crayfish (Procambarus clarkii Girard, 1852) and 11 populations of the spiny‐cheek crayfish (Faxonius limosus Rafinesque, 1817). We aimed at unravelling the ecological determinants and the mechanisms (neutral or adaptive) underlying the phenotypic variability among invasive populations. We demonstrate that, for each group of traits, P. clarkii and F. limosus display contrasting patterns of variance distribution across three ecological scales (population, sex, individual). Then, we demonstrate that P. clarkii trait variation in body morphology and stoichiometry is associated with both ecological and historical determinants (i.e. predation pressure, intraspecific invasion, and invasion age), and morphological traits in F. limosus vary with ecological factors only (i.e. predation pressure and abundance of P. clarkii). Finally, we highlight that different combinations of neutral and adaptive processes shaped the phenotypic variability in the two species, with a higher contribution of adaptive processes in F. limosus. Overall, these results indicate that F. limosus has already gone through local adaptation in the meta‐population while this has not yet occurred for P. clarkii, which was introduced later. This highlights that these two invasive species might have contrasting effects across ecological scales. Our study emphasises that studying invasive species can provide great knowledge on intraspecific variability and its ecological determinants and evolutionary processes in the wild. Our results also stress the need to focus on intraspecific variability in the context of biological invasions as it can be substantial across wide geographic areas.

“…2006), with almost 700 currently known species (Crandall and De Grave 2017). Owing to their substantial individual size and ability to reach high densities, their omnivorous nature and dominance in trophic interactions and ecosystem engineering (Reynolds and Souty-Grosset 2011), they play important ecological roles (Twardochleb et al 2013;Lipták et al 2019;Veselý et al 2020). Their introduction globally has been mostly for aquaculture, shery and ornamental purposes (Ackefors 2000;Faulkes 2015; Weiperth et al 2020), with resulting invasions generally leading to severe ecosystem and socioeconomic losses (Lodge et al 2012;Madzivanzira et al 2020).…”

Despite voluminous literature identifying invasive species impacts, understandings of monetary costs remain limited. Recently, profound impacts have been attributed to invasive crustaceans, but associated monetary costs lack synthesis. Here, we analyse globally reported costs of invasive freshwater crayfish across taxonomic, spatial and temporal descriptors. Moreover, we compare their cost magnitude to other invasive crustaceans — crabs, amphipods and lobsters. Between 2000 and 2020, crayfish caused US$ 1.28 billion in reported costs; the vast majority (95%) attributed to Astacidae (principally the signal crayfish Pacifastacus leniusculus) and the remainder to Cambaridae. According to reports, crayfish costs mostly impacted European economies (US$ 1.23 billion), followed by costs reported for North America and Asia. Despite well-known damages caused by invasive crayfish, costs were unreported elsewhere, highlighting knowledge gaps and challenges in cost quantifications. Invasive crayfish costs increased exponentially in the last two decades, averaging at US$ 61 million per-annum. Invasive crabs caused costs of similar magnitude (US$ 1.25 billion; US$ 53 million per-annum) but were mostly confined to North America (95%). Damage-related costs dominated for both crayfish (83%) and crabs (99%), with management spending lacking. Reported economic impacts from amphipods (US$ 178.8 thousand) and lobsters (US$ 44.6 thousand) were considerably lower. We identify burgeoning economic costs from these invasive groups yet highlight pervasive knowledge gaps at multiple scales. Further cost reporting is required to better-ascertain the true scale of monetary costs caused by invasive aquatic crustaceans.
