“…The intertidal zone represents a challenging environment for marine organisms since they need to cope with predictable and unpredictable temporal variability related to emersion, wave action, heating, and predation by terrestrial animals (Newell 1970, Sayer & Davenport 1991. Nevertheless, intertidal environments also provide high productivity, and consequently food availability, variability in microhabitat (possibly decreasing competition), and low predation pressure from strictly marine organisms (Newell 1970, Sayer & Davenport 1991, Gibson 2003.…”

Resident and transitory intertidal fish species are expected to differ in their utilization of space in the intertidal zone. Here we assessed fish zonation patterns on 2 rocky shores of the northwestern Adriatic Sea (where tides can range up to 1.5 m) using blennies as study species and distribution of both individuals and nests as methodological tools. Of the 12 species observed, 5 were found exclusively in the intertidal zone: Aidablennius sphynx, Coryphoblennius galerita, Lipophrys adriaticus, L. canevae and L. dalmatinus. Two species, Parablennius rouxi and P. tentacularis, were found only in the subtidal zone, whilst P. gattorugine, P. incognitus, P. sanguinolentus, P. zvonimiri and Salaria pavo were observed in both environments. Nest distribution mirrored individual distribution, strongly indicating that some blenny species can be considered true intertidal residents, spending the main part of their lives in this area. Intertidal and subtidal species showed different patterns of space utilization. Indeed, the former nested higher in the vertical distribution than the average depth at which individuals were recorded, and the latter, despite visiting the intertidal area at high tide, always nested below the minimum water line. These results show that, contrary to theoretical predictions, intertidal-resident fish may fully exploit intertidal habitats, for foraging and for reproduction, occupying even the sectors most distal from the subtidal zone, i.e. the most variable in terms of physical conditions. Moreover, nest distribution was found to be an effective measure of residence and thus a useful referent to evaluate space use in intertidal fish.

“…Ectosymbionts typically tolerate desiccation far less than their hosts; however, some species are capable of surviving overland migration. Ectoparasitic gyrodactylids are prone to desiccation but can survive on killifish (Rivulus hartii Boulenger, 1890), which migrate terrestrially (Sayer & Davenport, 1991;Cable et al, 2013), whilst aquatic leeches can be transported overland via crocodilians and waterfowl (Davies et al, 1982;Leslie et al, 2011). X. victoriensis is evidently capable of surviving translocation and dispersal due to the number of successful introductions and established populations across Europe (currently confirmed in seven countries; see James et al, 2015b).…”

“…In aquatic ecosystems, dispersal is usually limited to connected water bodies, with isolated habitats (such as ponds or lakes) only accessible via flooding events or anthropogenic activity (Hulme et al, 2008;Rahel & Olden, 2008). Amphibious behaviour, however, offers not only opportunities for foraging, reproduction and escape from unfavourable conditions, but terrestrial emigration to nearby water bodies (Sayer & Davenport, 1991). This has played an important role in the spread of invasive non-native species (Peterson et al, 2013;Marques et al, 2014;Ramalho & Anastácio, 2014;Fialho et al, 2016).…”

Transmission and terrestrial dispersal of non-native ectosymbionts on invasive crayfish

et al. 2018

Symbionts are a fundamental component of biological systems, and their survival is highly dependent on transmission and host movement. Ectosymbionts of amphibious animals face the added challenge of having to survive dramatic environmental changes as their hosts cross ecosystem boundaries. Within freshwaters, crayfish are amongst the most widespread invasive species that readily disperse overland and are host to a wide range of ectosymbionts. Relatively little is known about the transmission of these ectosymbionts, including their ability to survive overland host migration. Here, we assessed terrestrial emigration and both inter-and intra-specific transmissions of Xironogiton victoriensis, a nonnative branchiobdellidan (Annelida: Clitellata) recently found on invasive signal crayfish (Pacifastacus leniusculus) in the UK. These branchiobdellidans tolerated desiccation and did not alter host terrestrial behaviour. Transmission was rapid between natural signal and novel virile (Orconectes cf. virilis) crayfish hosts, with host interactions facilitating transmission.Thus, branchiobdellidans can disperse via amphibious host behaviour and readily infect novel hosts. These traits facilitate symbionts' survival and provide access to additional dispersal pathways that are likely to aid transmission.

“…Here, we define amphibious species as those that naturally spend part of their life on land (Gordon et al, 1968;Graham, 1997). Emersion may be related to feeding and/or foraging, reproduction, predator avoidance, migration, competition, habitat drying and/or poor water conditions (Sayer and Davenport, 1991;Graham, 1997). Correspondingly, there is a tremendous diversity of strategies for coping with life out of water.…”

Amphibious fishes: evolution and phenotypic plasticity

Amphibious fishes spend part of their life in terrestrial habitats. The ability to tolerate life on land has evolved independently many times, with more than 200 extant species of amphibious fishes spanning 17 orders now reported. Many adaptations for life out of water have been described in the literature, and adaptive phenotypic plasticity may play an equally important role in promoting favourable matches between the terrestrial habitat and behavioural, physiological, biochemical and morphological characteristics. Amphibious fishes living at the interface of two very different environments must respond to issues relating to buoyancy/gravity, hydration/ desiccation, low/high O 2 availability, low/high CO 2 accumulation and high/low NH 3 solubility each time they traverse the air-water interface. Here, we review the literature for examples of plastic traits associated with the response to each of these challenges. Because there is evidence that phenotypic plasticity can facilitate the evolution of fixed traits in general, we summarize the types of investigations needed to more fully determine whether plasticity in extant amphibious fishes can provide indications of the strategies used during the evolution of terrestriality in tetrapods.
