An ethogram of body patterning behavior in the biomedically and commercially valuable squid Loligo pealei off Cape Cod, Massachusetts.
Squids have a wide repertoire of body patterns; these patterns contain visual signals assembled from a highly diverse inventory of chromatic, postural, and locomotor components. The chromaticExpand

THE RISK OF CANNIBALISM AND MALE MATING BEHAVIOR IN THE MEDITERRANEAN PRAYING MANTID, IRIS ORATORIA
This study examined male behavior in response to the risk of cannibalism in the Mediterranean praying mantid, Iris oratoria (Mantodea: Mantidae). The risk of cannibalism was manipulated by placingExpand

Examinations of Female Pheromone use in Two Praying Mantids, Stagmomantis limbata and Tenodera Aridifolia Sinensis (Mantodea: Mantidae)
ABSTRACT Female pheromones were examined in two species of praying mantids: Stagmomantis limbata Hahn and the Chinese mantid, Tenodera aridifolia sinensis Saussure. As in other mantids, females ofExpand

Effects of female feeding regime in a sexually cannibalistic mantid: fecundity, cannibalism, and male response in Stagmomantis limbata (Mantodea)
1. Female feeding regime exhibited a cascade of effects on reproductive biology and behaviour in the mantid Stagmomantis limbata (Hahn).

Temporal dynamics of mating and paternity in the squid Loligo pealeii
We investigated short-term changes in relative paternity among a female's offspring in the long-finned squid Loligo pealeii. We conducted mating trials in the laboratory in which a single femaleExpand

Seasonal Adult Sex Ratio Shift in the Praying Mantid Iris oratoria (Mantodea: Mantidae)
The adult sex ratio of the praying mantid Iris aratoria L. becomes increasingly female-biased as the season progresses. This 3-yr field study examines 3 possible causes of this shift in sex ratio:Expand

Lifetime mating opportunities and male mating behaviour in sexually cannibalistic praying mantids
I examined the number of lifetime mating opportunities and mating behaviour of males in two sexually cannibalistic species, the Mediterranean, Iris oratoria, and bordered, Stagmomantis limbata,Expand

Microsatellite DNA markers indicate a high frequency of multiple paternity within individual field-collected egg capsules of the squid Loligo pealeii
Previous behavioral observations of Loligo pealeii revealed the potential for multiple paternity within individual egg capsules, each containing 100 to 300 eggs. Five egg capsules, sam- pled from 3Expand

Does a single meal affect female reproductive output in the sexually cannibalistic praying mantid Iris oratoria?
1. One explanation of the evolution of sexual cannibalism, the female’s consumption of a male during or following courtship or copulation, is that this behaviour increases the female’s fitness. ThisExpand
