Impact of Beach Restoration on the Deep-burrowing Ghost Shrimp, Callichirus islagrande [PDF]

open access: yesJournal of Coastal Research, 2004
Restorations of barrier islands can be beneficial to coastal marshes, but may also have detrimental effects on intertidal macrobenthic communities. Two barrier islands of the Isles Dernieres chain of Louisiana were recently renourished with dredged sediments taken from the adjacent estuary.

Hydraulic activities by ghost shrimp Neotrypaea californiensis induce oxic−anoxic oscillations in sediments [PDF]

open access: yesMarine Ecology Progress Series, 2012
Porewater pressure sensing, time-lapse photography, and planar optode imaging of oxygen were applied to investigate hydraulic activities by thalassinidean ghost shrimp Neo - trypaea californiensis and the associated dynamics of oxygen in and around their burrows. Ghost shrimp were hydraulically active 40% of the time. For >90% of this time the sediment

Two new burrowing mud shrimps of the genus Gilvossius from the Gulf of Mexico (Crustacea: Decapoda: Callianassidae)

open access: yesNauplius, 2020
Previous reports of Gilvossius setimanus (De Kay, 1844) from the Gulf of Mexico have been based on a population of small specimens from deep offshore continental shelf waters off Texas and larger specimens from shorelines and shallow embayments of ...

Systematics, phylogeny, and taphonomy of ghost shrimps (Decapoda): a perspective from the fossil record [PDF]

open access: yesArthropod Systematics & Phylogeny, 2015
Ghost shrimps of Callianassidae and Ctenochelidae are soft-bodied, usually heterochelous decapods representing major bioturbators of muddy and sandy (sub)marine substrates. Ghost shrimps have a robust fossil record spanning from the Early Cretaceous (~ 133 Ma) to the Holocene and their remains are present in most assemblages of Cenozoic decapod ...

New Early Cenozoic ghost shrimps (Decapoda, Axiidea, Callianassidae) from Pakistan and their palaeobiogeographic implications [PDF]

open access: yesGeodiversitas, 2016
A new set of Paleocene and Eocene decapod crustaceans is described from the Kirthar Range of Pakistan. Two new ghost shrimps (Crustacea, Decapoda, Callianassidae) are described: Neocallichirus khadroensis Hyžný & Charbonnier, n. sp. from the Paleocene (Danian, Khadro Formation) of Gawar Band, Ranikot District, and Neocallichirus lakhraensis Hyžný ...

Impacts of Burrowing Ghost Shrimp, Genus Lepidophthalmus Crustacea: Decapoda: Thalassinidea, on Penaeid Shrimp Culture

open access: yesJournal of the World Aquaculture Society, 1998
Abstract The burrowing ghost shrimp Lepidophthalmus sinuensis Lemaitre and Rodrigues and Lepidophthalmus bocourd (A. Milne Edwards) have significant impacts on pond‐based culture of penaeid shrimp. Marked abbreviation of the larval cycle, an adaptation for estuarine retention in wild populations, favors accumulation of recruits into the same substrates

Relative growth, sexual maturity and handedness in the ghost shrimp Callichirus major (Decapoda: Callianassidae) from the southwestern Atlantic

open access: yesScientia Marina, 2019
Biometric studies provide valuable information about changes associated with the growth and sexual maturity of living organisms. We analysed sexual dimorphism, allometric growth, sexual maturity and handedness in the ghost shrimp Callichirus major at ...
