2000 journal article

Temporal shift in the presence of a chemical cue contributes to a diel shift in sociality

ANIMAL BEHAVIOUR, 59(2000 Apr.), 793–799.

By: S. Ratchford n & D. Eggleston n 

TL;DR: The results suggest that the chemical cues for aggregation, released by spiny lobsters, are present discontinuously, that spiny Lobsters are influenced by conspecific odours continuously, and that aggregation is controlled by temporal variation in the presence of a chemical cue.

1998 journal article

Size- and scale-dependent chemical attraction contribute to an ontogenetic shift in sociality

ANIMAL BEHAVIOUR, 56(4), 1027–1034.

By: S. Ratchford n & D. Eggleston n 

TL;DR: The results of this study suggest that the earliest benthic stages of Caribbean spiny lobsters are unresponsive to conspecific odours, but lobsters greater than 15 mm in carapace length are attracted by conspecial odours; and large lobsters produce a sufficient quantity of scent to attract Conspecifics over distances of at least a few metres, whereas small lobsters cannot.

1998 journal article

Spatiotemporal variation in postlarval recruitment of the Caribbean spiny lobster in the central Bahamas: lunar and seasonal periodicity, spatial coherence, and wind forcing

MARINE ECOLOGY PROGRESS SERIES, 174(1998 Nov. 26), 33–49.

By: D. Eggleston n , R. Lipcius  n, L. Marshall & S. Ratchford n

author keywords: environmental forcing; Panulirus argus; larval supply; recruitment; settlement; spiny lobster
TL;DR: It is indicated that artificial settlement substrates provide a reliable index of postlarval supply to inshore nursery habitats, and that a combination of stochastic and deterministic forces influence recruitment over various scales of time and space. (via Semantic Scholar)
