On the Heterotreme - Thoracotremedistinction in the Eubrachyurade Saint Laurent , 1980 ( Decapoda , Brachyura )
Eubrachyurans are currently divided into two subsections based on the anatomical position of the seminal duct termini. Heterotremes have the seminal ducts passing through the pereiopod 5 coxae, emerging externally in the form of “penes” to contact the basal segments of the gonopods. Thoracotrematous crabs, on the other hand, have the “male openings” located on sternite 8 and the ejaculatory duc...

متن کاملCodage de la parole a bas et tres bas debits
This paper reviews the main algorithms for speech coding at low and very low bit rates, from 50 bps to 4000 bps. Then the HSX technique for coding at 1200 bps and a new segmental method with automatically derived units for very low bit rate coding are presented in details.
متن کاملGhost shrimp Calliax de Saint Laurent, 1973 (Decapoda: Axiidea: Callianassidae) in the fossil record: systematics, palaeoecology and palaeobiogeography
Ghost shrimps of the family Callianassidae are very common in the fossil record, but mostly as isolated cheliped elements only. The assignment to biologically defined genera, diagnosed on the basis of soft part morphology, is thus rather difficult. In this respect, proxy characters present on chelipeds that are the most durable ghost shrimp remains are needed to ascribe fossil material to extan...
متن کاملMorphometric Relationships Between the Hermit Crab Isocheles sawayai (Forest & Saint Laurent) (Crustacea Anomura Diogenidae) and its Shell from Southern Brazil
A study on morphometric relationships between the hermit crab Isocheles sawayai and its shell in a population from Paraná-Santa Catarina States coast was carried out. Hermit crabs from the by-catch of shrimp fishing (4-15m depth) were collected. Cephalothoracic shield length (CL) and width (CW) from hermit crabs and total length (SL), aperture length (AL) and weight (SW) from shells were taken....
