Cryptic species and population structuring of the Atlantic and Pacific seabob shrimp species, Xiphopenaeus kroyeri and Xiphopenaeus riveti

Marine Biology, 2006
Seabob shrimps of the genus Xiphopenaeus are important fishery resources along the Atlantic and Pacific coasts of Central and South America. The genus was considered to comprise two species: the Atlantic Xiphopenaeus kroyeri (Heller, Sitzungsber Math Naturwiss cl kaiserliche Akad Wiss Wien 45:389–426, 1862), and the Pacific Xiphopenaeus riveti (Bouvier,

Multilocus data reveal cryptic species in the Atlantic seabob shrimp Xiphopenaeus kroyeri (Crustacea: Decapoda)

open access: yesBiological Journal of the Linnean Society, 2019
AbstractThe recognition of cryptic biodiversity provides valuable insights for the management of exploited species. The Atlantic seabob shrimp (Xiphopenaeus kroyeri) is a commercially important fishery resource in the Guianan ecoregion, South America. Previous research in Brazil suggested the presence of cryptic species within the genus.

Oxygen Consumption and Ammonia Excretion During the Moulting Cycle in the Shrimp Xiphopenaeus kroyeri

Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 1998
Abstract Xiphopenaeus kroyeri (Heller, 1862) is one of the main contributors to the benthic megafauna biomass in Sao Paulo State littoral coast (Brazil). Routine respiration ( R ) and ammonia–N excretion ( U ) rates, defined as those measured during minimum but uncontrolled activity, were quantified in different-sized shrimps at stages C/D 0 , A/B,

Exploring chitin morphologies in cuticle fragments of Xiphopenaeus kroyeri by atomic force microscopy

Carbohydrate Polymers, 2002
Abstract Shells of Xiphopenaeus kroyerishrimp were submitted to mild acid and alkaline treatments to produce α chitin films, which were characterised by infrared spectroscopy. Dynamic AC operational mode atomic force microscopy (AFM) was used to image the external surface and regions of an inner surface of the cuticle. All samples were scanned in air.
