Kelp habitats are in decline in many temperate coastal regions of the world due to climate change and expansion of populations of grazing urchins. The loss of kelp habitat may influence the vulnerability to predators of the juveniles of commercially important species. In this study relative predation rates for kelp versus barren reef habitat were measured for early juvenile Australasian spiny lobster, Jasus edwardsii (Hutton, 1875), on the northeastern coast of New Zealand using tethering methods. Variation in assemblages of predators over small spatial scales appeared to be more important for determining the relative predation of lobsters, regardless of habitat type. Therefore, the assessment of relative predation risk to early juvenile lobsters between kelp and barren habitats will require more extensive sampling at a small spatial scale, as well as a specific focus on sampling during crepuscular and nocturnal periods when these lobsters are most at risk of predation.

Spiny lobsters use refuge habitat and gregarious behaviour to reduce predation risk, particularly in their vulnerable juvenile and subadult stages. We characterised patterns of sheltering behaviour in the California spiny lobster (Panulirus interruptus (Randall)) on southern California rocky reefs and used manipulative experiments to examine how these behaviours affect the survival of subadult lobsters and shelter selection. Lobsters generally were gregarious and subadults were commonly found inhabiting shelters with adult lobsters. Tethering experiments with subadults indicated that communal denning increases the odds of survival only when adult lobsters are part of aggregations. This corresponded to results from a shelter choice experiment in the laboratory, where the presence of predators caused subadults to shelter more often with adult conspecifics rather than other subadults. Despite the gregarious nature of P. interruptus, solitary subadults were common at all sites. Although field experiments clearly indicated that solitary lobsters increased their odds of survival by inhabiting shelters scaled to body size, evidence that lobsters exhibit shelter scaling on natural reefs was mixed. Our results indicate that subadult P. interruptus exhibit similar behavioural strategies as other spiny lobsters to reduce predation risk, and they provide a more comprehensive examination of P. interruptus behaviour than previously available.

AbstractAs acute stress induced by predation risk can generate significant oxidative damage, prey organisms are forced to balance their defence reaction and the cost of activating the cellular defence system. Stress tolerance differs significantly among species; therefore predator pressure indirectly shapes the community structure. To test adaptation abilities of amphipod crustaceans (Dikerogammarus villosus and Gammarus jazdzewskii) we exposed them to acute (35 min.) and chronic (1 or 7 days) predation risk (the Eurasian perch). We measured respiration (related to metabolic rate), cellular defence systems (antioxidant enzyme (catalase) activity and heat shock protein (Hsp70) concentration), and the level of oxidative damage (thiobarbituric acid reactive substances (TBARS) concentration). Both amphipods increased their respiration rate in the presence of predation cues, irrespective of the duration of their pre-exposure to danger. This increase in D. villosus was initiated more quickly (immediately vs. after 10 min. of the test) and lasted for a longer time (20 vs. 10 min.) than in G. jazdzewskii. However, only G. jazdzewskii after a short exposure to predation risk exhibited an increase in its catalase activity, Hsp70 concentration and oxidative damage. No changes in these parameters were exhibited by D. villosus or after a chronic exposure of G. jazdzewskii to predation cues. Our results show that prey organisms are able to reconfigure their physiology to maintain increased metabolic rate under prolonged predator pressure and, at the same time, reduce oxidative damage as well as costs related to anti-oxidant defence.

Is individual variation in metabolic rate related to growth of spiny lobster in culture and what is the influence of social interaction?
