“…It is reasonable to expect that immersion of eggs is essential, at least at the very early stages of embryonic development (Niksirat et al., , ), and it has been documented that oviposition cannot occur in P. clarkii without free water (McClain, ). Artificially stored eggs of the signal crayfish and white‐clawed crayfish need to be transferred to aquatic conditions once the 12th stage of embryonic development is attained (Celada et al., ; Pérez et al., ).…”

“…McMahon and Stuart () present evidence that crayfish exposed to long periods out of water as a result of severely depleted oxygen levels and enriched carbon dioxide levels in small pools of water (typical of water in burrows) eventually become taxed to the point that recovery is difficult. It has recently been documented that spawning in P. clarkii cannot occur in the absence of free water and oviposition was delayed for a period of time until free water was returned in a simulated burrow study (McClain, ). As a result, reproductive failure may explain the decline of some crayfish species (Lodge, Taylor, Holdich, & Skurdal, ; Taylor et al., ) under prolonged drought.…”

“…While it is becoming more obvious that oviposition in crayfish is hampered or delayed in burrows lacking free standing water, the effects of high humidity on embryogenesis is largely unknown (McClain, 2013;Niksirat, Kouba, & Kozák, 2014, 2015. However, survival and reproduction of crayfish individuals in burrows over extended periods of time without free water have been demonstrated (Jordan, Babbitt, McIvor, & Miller, 2000;Kouba et al, 2016;McClain, 2013;McClain & Romaire, 2004). Due to its exclusively parthenogenetic mode of reproduction, burrowing behaviour and potential invasive abilities (Gutekunst et al, 2018;Scholtz et al, 2003), P. virginalis is a suitable model species to study the effect of seasonal water level fluctuations on the early life-history traits of crayfish living in intermittent aquatic environments (Hossain, Patoka, Kouba, & Buřič, 2018).…”

High air humidity is sufficient for successful egg incubation and early post‐embryonic development in the marbled crayfish (Procambarus virginalis)

Severe weather events, such as long‐term droughts, are challenging for many freshwater species. To survive drought, freshwater crayfish tend to inhabit shelters or burrows where they can remain in contact with water or high humidity environments. However, it is not known whether embryogenesis or post‐embryonic development can occur without free standing water. To address this question, three experiments were conducted using artificial burrows with high air humidity and using marbled crayfish (Procambarus virginalis Lyko, 2017) as a model species. Marbled crayfish are capable of parthenogenetic reproduction, burrow extensively and are able to travel long distances over land. In the first experiment, ovigerous females were transferred to simulated burrows without free water, but with high air humidity. A control group of females were kept in burrows with free water. Successful hatching was achieved in both groups. In the second experiment, ovigerous females were transferred to simulated burrows with no free water but high air humidity and post‐embryonic development were observed. Following successful hatching, offspring moulted to the second developmental stage (stage 2 juveniles). Stage 2 juveniles remained viable without free water for 20 days, but further development was not observed. However, when some of these stage 2 juveniles were placed back into fully aquatic conditions (experiment 3), they moulted to stage 3 within 4 to 8 days. These results demonstrated the ability of marbled crayfish to undergo terminal phases of embryogenesis, including hatching, as well as early post‐embryonic development under high air humidity conditions only. Post‐embryonic development was suspended in the absence of free water, and successfully resumed when re‐immersed. This similar ability to tolerate drought‐like conditions during post‐embryonic development may also occur in other crayfish species, especially primary burrowers. This unprecedented life history trait may be crucial for inhabiting ecosystems with rapidly changing water regimes. In drying climates, it may confer advantages on some crayfish species (including some invasive species) over others.

Triggers affecting crayfish burrowing behaviour

Surface water inhabiting crayfish are well-known for the impact on their surroundings. This impact has been related to loss of biodiversity and deteriorating water quality for invasive crayfish. Crayfish dig burrows for various reasons like lack of natural shelters, avoiding an upcoming drought, or high crayfish density and this may lead to increased sediment transport and accelerated bank instability. All crayfish are considered to have burrowing capability, but not all species have been observed burrowing. Studies comparing this behaviour among different species in standardized ways are scarce. Crayfish burrowing was investigated under standardized laboratory conditions to reveal differences among species and their sex. All studied species occur in the Netherlands and were the native Astacus astacus (Linnaeus, 1758), the Eurasian Pontastacus leptodactylus (Eschscholtz, 1823) and the invasive North American Faxonius virilis (Hagen, 1870), F. limosus (Rafinesque 1817), Pacifastacus leniusculus (Dana, 1852), Procambarus acutus (Girard 1852), and P. clarkii (Girard, 1852). As burrowing triggers were evaluated presence of shelter, increased light intensity, increased water temperature, and increased crayfish density. Results showed species-specific and sometimes sex-specific differences in burrowing behaviour among crayfish. The response to burrowing triggers was also species-specific and no two species reacted identical to all triggers. Absence of shelter was a strong driver to burrow for A. astacus, F. limosus and F. virilis, while increased light intensity triggered burrowing behaviour in P. leptodactylus, P. acutus and P. clarkii and lowered activity of F. limosus. Burrowing behaviour of P. clarkii was mostly influenced by increased water temperature. Significant differences between females and males were observed for P. leptodactylus, P. leniusculus and P. acutus in the shelter, increased density and increased water temperature treatment, respectively. Understanding the triggers that invoke burrowing may help managing populations of these invasive species.
