Home range dynamics of the American lobster,Homarus americanus

Effects of temperature on the moulting and locomotory activity of hatchery-reared juvenile lobsters (Homarus gammarus) at Helgoland (North Sea)

“…may depend on their size, sex and specific behavioural patterns (foraging, moulting, mating, dominance and territorial behaviour) (Branford 1979;Lawton 1987;Karavanich & Atema 1998;Mehrtens et al 2008;Schmalenbach et al 2011). So far, field studies that quantified movement in adult lobsters reported no significant differences in home ranges between lobster size and sex (Scopel et al 2009;Moland et al 2011b).…”

Influence of predator identity on the strength of predator avoidance responses in lobsters

“…During the day, no noticeable difference in sheltering behavior was observed among treatments likely because American lobsters are primarily nocturnal (Karnofsky et al, 1989;Scopel et al, 2009;Wahle, 1992) and spent the majority of their time in refuge habitat during the day. We found that lobsters reacted to all three predator species when encountered (i.e., b1 m distance between predator and lobster; personal observation).…”

Biotelemetry of crustacean decapods: sampling design, statistical analysis, and interpretation of data

“…On the other hand, small-scale movements have been approached with the use of automatic positioning systems (mainly using VRAP technology, from VEMCO Radio Acoustic Positioning, Vemco Ltd. Halifax, Canada), specifically in studies on H. americanus and Paralithodes camtschaticus (Tilesius, 1815) (see Golet et al, 2006;Jorgensen et al, 2007;Scopel et al, 2009;Watson et al, 2009). The implementation of these two systems (GIS and VRAP) has allowed substantial improvements in the knowledge of ecological aspects of these species.…”
