“…Cheliped displays were good predictors of which species was likely to win an encounter; such displays were used as indicators of the relative aggressive 'drive state' of the animal to claim a limited resource (Hazlett & Bossert 1965). Pachygraspus marmoratus made extensive use of cheliped displays compared to P. gibbesi (Figure 8).…”

Spatial and bathymetric distribution, population density, habitat preferences, fecundity, breeding season and interspecific interactions of the alien grapsoid crab Percnon gibbesi (H. Milne-Edwards, 1853) from the Maltese Islands (Malta and Gozo) are compared among localities in the Mediterranean where established populations have been reported since 1999. In the Maltese Islands, habitat preferences and bathymetric distribution were similar to those in other Mediterranean localities. Spatial distribution was found to be limited by the availability of the boulder habitat in which this crab nearly always occurs. Fecundity was higher in the Maltese Islands than in Linosa and Lampedusa, the breeding season lasting from the end of May until September. On Maltese shores the habitat of the alien overlapped with that of the native grapsid Pachygrapsus marmoratus (Fabricius, 1787) (Crustacea: Brachyura: Grapsoidea) and, to a lesser extent, that of the native xanthid Eriphia verrucosa (Forskål, 1775). Laboratory studies to assess the possible interactions of the alien species with P. marmoratus suggest that the latter shows a competitive advantage over P. gibbesi, since 80.8% of encounters between the two species were initiated by P. marmoratus, and in 80% of the encounters it prevailed. This suggests that P. marmoratus is unlikely to be excluded from its natural habitat by the alien species, and that significant spatial resource partitioning on the part of P. marmoratus is unlikely to occur.

“…We followed the methods of Hazlett and Bossert (1965), Dingle (1969), Losey (1978), Steinberg (1977), and Huber and Kzravitz (1995), but we limited our analysis to inter-individual sequences since our exclusive interest was to describe the exchange of information occurring between the two interacting individuals.…”

“…This analysis furnishes suggestions on whether the BP i influenced the BP j that followed, addressing the question of whether the behavior performed by one crayfish had an effect on the subsequent behavior of the opponent. The influence can be either 'directive' or 'inhibitory' (in a statistical sense without any implication of causation, see Bossert, 1965 andDingle, 1969), when the observed frequency is significantly higher or lower than the expected one, respectively.…”

“…Therefore, the next step in the analysis was to work with trigrams of the type A 1 -i-j and/or with tetragrams of the type A 2 -A 1 -i-j. The frequency distributions of BPs j following A 1 -i and of BPs j following A 2 -A 1 -i, were compared with the frequency distribution of BPs j following i regardless of the preceding BPs (see, also Bossert, 1965, andDingle, 1969).…”

“…However, after a flourishing of studies in the 60s and 70s (e.g. Haldane and Spurway, 1954;Wilson, 1962;Altmann, 1965;Hazlett and Bossert, 1965;Dingle, 1969Dingle, , 1972Steinberg and Conant, 1974;Preston, 1978), the identification of both conceptual and technical pitfalls of the information analysis (Wilson, 1975) seems to have hampered a formal assimilation of information theory within the theoretical corpus of ethology.…”

Information theory measures provided useful quantitative tools for describing the transfer of information in interacting pairs of the eastern white-river crayfish, Procambarus acutus acutus, and furnished hints for deciphering the dynamics, structure, and organization of the agonistic repertoire in this species. As a confirmation of the predictive and heuristic potentials of the theory, results suggested hypotheses on the mechanisms underlying the formation and maintenance of dominance hierarchies in crayfish and indicated the directions that future developments of the research should follow.
