A Western Range Extension For Caprella Scaura (Amphipoda: Caprellidae) In The Aransas Bay Ecosystem, Texas, Nicholas L. Ahrens, Faye P. Grubbs
A Western Range Extension For Caprella Scaura (Amphipoda: Caprellidae) In The Aransas Bay Ecosystem, Texas, Nicholas L. Ahrens, Faye P. Grubbs
Gulf and Caribbean Research
During March 2009, the skeleton shrimp Caprella scaura and Paracaprella tenuis (Amphipoda: Caprellidae) were collected from several locations throughout the Aransas Bay, Texas ecosystem from Texas Parks and Wildlife fishery—independent trawl and oyster dredge samples. This is a western range expansion for C. scaura; P. tenuis has been reported from this area before. Both species were exclusively associated with a bryozoan, Bugula neritina. Densities of both species ranged between 0.1–3.4 individuals per gram of attached bryozoans. A reproductive population is likely established since several sizes, including adult males and gravid females, were observed. No caprellids were observed after …
Caribbean Leucothoidae (Crustacea: Amphipoda) Of Panama, Kristine N. White
Caribbean Leucothoidae (Crustacea: Amphipoda) Of Panama, Kristine N. White
Gulf and Caribbean Research
Leucothoid amphipods were collected from sponge, ascidian, and bivalve mollusk hosts around Bocas del Toro, Panama. New host and locality records are reported for 10 species. Morphological variation is noted in some species originally described from Belize and South Florida. Future molecular research will help to clarify the importance of this variation. A key to the Caribbean species of the Leucothoidae collected around Bocas del Toro, Panama is provided based on morphological characters.
Amphipods Of The Family Ampeliscidae (Gammaridea). Iv. Infraspecific Variation In Ampelisca Agassizi, Gary D. Goeke, Richard W. Heard
Amphipods Of The Family Ampeliscidae (Gammaridea). Iv. Infraspecific Variation In Ampelisca Agassizi, Gary D. Goeke, Richard W. Heard
Gulf and Caribbean Research
Considerable variation noted, in Ampelisca agassizi is herein described. The variations in the shape of the basis of pereopod 7 and the carina of urosomite I are most obyious. No relationship was found with the atypical specimens and their age, associated sediment or location.
Amphipods Of The Family Ampeliscidae (Gammaridea). Iii. Ampelisca Parapacifica, A New Species Of Amphipod From The Western North Atlantic With The Designation Of A Substitute Name For A. Eschrichtii Pacifica Gurjanova, 1955, Gary D. Goeke, Richard W. Heard
Amphipods Of The Family Ampeliscidae (Gammaridea). Iii. Ampelisca Parapacifica, A New Species Of Amphipod From The Western North Atlantic With The Designation Of A Substitute Name For A. Eschrichtii Pacifica Gurjanova, 1955, Gary D. Goeke, Richard W. Heard
Gulf and Caribbean Research
A new species of benthic amphipod, Ampelisca parapacifica, is described from the southeastern Gulf of Mexico and compared with the closely allied Ampelisca pacifica Holmes, 1908, from the eastern Pacific. The distinctive form of the third uropod separates this species pair from other members of the "macrocephala" subgroup of the genus Ampelisca Kroyer, 1842. Ampelisca parapacifica is distinguished from A. pacifica by antenna I peduncle segment 2 less t}an twice the length of article 1 and uropod I peduncle shorter than the rami. Previous Atlantic records of A. pacifica are assigned to the proposed new species. The Pacific populations …
Amphipods Of The Family Ampeliscidae (Gammaridea). I. Ampelisca Bicarinata, A New Species Of Amphipod From The Gulf Of Mexico, Gary D. Goeke, Richard W. Heard
Amphipods Of The Family Ampeliscidae (Gammaridea). I. Ampelisca Bicarinata, A New Species Of Amphipod From The Gulf Of Mexico, Gary D. Goeke, Richard W. Heard
Gulf and Caribbean Research
A new species of the benthic amphipod genus Ampelisca Kroyer, is described and illustrated. Previous records of the Pacific species Ampelisca cristoides Barnard, 1954, from the western North Atlantic are now assignable to the proposed new species, Ampelisca bicarinata. These two closely related sibling species are compared and their specific differences enumerated.
Amphipods Of The Family Ampeliscidae (Gammaridea). Ii. Notes On The Occurrence Of Ampelisca Holmesi In The Northern Gulf Of Mexico, Gary D. Goeke, Jerry M. Gathof
Amphipods Of The Family Ampeliscidae (Gammaridea). Ii. Notes On The Occurrence Of Ampelisca Holmesi In The Northern Gulf Of Mexico, Gary D. Goeke, Jerry M. Gathof
Gulf and Caribbean Research
Ampelisca holmesi is reported herein from the grass beds behind the barrier islands of the northern Gulf of Mexico. Previous records are reviewed and the male of the species is described for the first time. The material agrees well with the original description and the recent redescription. Mouthparts for A. holmesi are described, illustrated, and compared with those of A. verrilli from the northeastern coast of the United States.
