Paleocene Thalassinidea colonization in deep-sea environment and the coprolite Palaxius osaensis n. ichnosp. in Southern Costa Rica [PDF]

Revue De Micropaleontologie, 2009
Palaxius osaensis n. ichnosp., a new ichnospecies of crustacean coprolite is described. The coprolite is preserved in a 200-m thick Paleocene sequence in Southern Costa Rica that is largely dominated by pillow basalts.

The Biology of Upogebia pusilla (PETAGNA) (Decapoda, Thalassinidea)

Marine Ecology, 1988
Abstract. Populations of the thalassinidean shrimp Upogebia pusilla were studied on tidal flats in the Northern Adriatic Sea. Biometric analysis showed a sexual dimorphism, especially in propodus size. Size frequency distributions revealed the presence of large animals during all seasons; recruitment by juveniles occurred in autumn.

Lactate formation in Callianassa californiensis and Upogebia pugettensis (Crustacea: Thalassinidea)

Marine Biology, 1979
The ability to accumulate lactate as a result of laboratory exposure to anoxia was examined in 2 species of mud-dwelling shrimp, the ghost shrimp Callianassa californiensis and the mud shrimp Upogebia pugettensis. Hemolymph lactate accumulated to a much greater degree in the mud shrimp, even though the overall levels of lactate dehydrogenase activity ...

Critical evaluation of sediment turnover estimates for Callianassidae (Decapoda: Thalassinidea)

Journal of Experimental Marine Biology and Ecology, 1993
Abstract Members of the decapod family Callianassidae influence sediment dynamics and ecosystem function via their bioturbation activities. The latter is currently assessed by measures of sediment turnover rates which are collected, calculated and expressed by different methods.

The biology of Calocaris macandreae [Crustacea: Thalassinidea]

Journal of the Marine Biological Association of the United Kingdom, 1963
Previous work on the biology and distribution of Calocaris is discussed briefly. The distribution in Northumberland waters is considered in relation to depth and bottom sediment.Quantitative monthly samples show that population numbers remain very stable throughout the year. A well marked egg-laying period occurs in January-February when relatively few

On the burrows ofLepidophthaltnus louisianensis (Schmitt 1935) (Decapoda: Thalassinidea: Callianassidae)

Senckenbergiana maritima, 2000
Two resin casts of the burrows of the thalassinidean decapodLepidophthalmus louisianensis were madein situ on a tidal flat at Dauphin Island, Alabama. The following burrow sections can be recognised: an upper narrow shaft leading from the surface to a depth between 17 and 28 cm; a main wider shaft with several chambers leading to a depth of more than 1
