Distribución Y Abundancia De Larvas De Langostino Colorado Pleuroncodes Monodon Frente a La Costa De Concepción, Chile
Invest. Mar., Valparaíso, 22: 13-29, 1994 Distribución de larvas de langostino colorado 13 Distribución y abundancia de larvas de langostino colorado Pleuroncodes monodon frente a la costa de Concepción, Chile SERGIO PALMA G. Escuela de Ciencias del Mar Universidad Católica de Valparaíso Casilla 1020, Valparaíso, Chile RESUMEN. Se analiza la distribución y abundancia de larvas de langostino colorado Pleuroncodes monodon captura- das en cuatro cruceros oceanográficos efectuados entre abril y diciembre de 1991, frente a la costa de Concepción, Chile. Las muestras de zooplancton se obtuvieron en 15 estaciones oceanográficas, mediante pescas oblicuas con redes Bongo desde el fondo a superficie, con un máximo de 200 m de profundidad. En todos los cruceros realizados se observó la presencia de larvas de langostino, encontrándose la mayor abundancia en noviembre. Las mayores densidades de larvas se detectaron en aguas sobre la plataforma continental, particularmente en el norte del área de estudio. La biomasa zooplanctónica alcanzó valores máximos en abril y mínimos en junio, registrándose las mayores densidades en aguas de la plataforma, en el norte y sur del área de estudio. La distribución temporal de los distintos estados de desarrollo (zoeas y postlarvas), sugiere el desplazamiento desde la costa hacia el talud, a medida que avanza la metamorfosis larval. La distribución vertical de las larvas mostró una preferencia de los estados de zoea por el estrato 0-25 m, mientras que las postlarvas se concentraron en el estrato 25-50 m. Bajo 50 m de profundidad, se observó una escasa cantidad de individuos. Palabras claves: Pleuroncodes monodon, larvas langostino colorado, biomasa zooplancton, distribución espacio-temporal, abundancia. -

ZooKeys 935: 25–35. https://doi. org/10.3897/zookeys.935.51931 Abstract Hendersonida parvirostris sp. nov. is described from Papua New Guinea. The new species can be distin- guished from the only other species of the genus, H. granulata (Henderson, 1885), by the fewer spines on the dorsal carapace surface, the shape of the rostrum and supraocular spines, the antennal peduncles, and the length of the walking legs. Pairwise genetic distances estimated using the 16S rRNA and COI DNA gene fragments indicated high levels of sequence divergence between the new species and H. granulata. Phylogenetic analyses, however, recovered both species as sister species, supporting monophyly of the genus. Keywords Anomura, mitochondrial genes, morphology, West Pacific Introduction Squat lobsters of the family Munididae Ahyong, Baba, Macpherson & Poore, 2010 are recognised by the trispinose or trilobate front, usually composed of a slender rostrum flanked by supraorbital spines (Ahyong et al. -
How to Become a Crab: Phenotypic Constraints on a Recurring Body Plan

For over 140 years, convergent evolution of the crab-like body plan (with a wide and flattened shape, and a bent abdomen) at least five times in decapod crustaceans has been known as ‘carcinization’. The repeated loss of this body plan has been identified as ‘decarcinization’. We offer phylogenetic strategies to include poorly known groups, and direct evidence from fossils, that will resolve the pattern of crab evolution and the degree of phenotypic variation within crabs. Proposed ecological advantages of the crab body are summarized into a hypothesis of phenotypic integration suggesting correlated evolution of the carapace shape and abdomen. Our premise provides fertile ground for future studies of the genomic and developmental basis, and the predictability, of the crab-like body form.

The oxygen minimum zones in this region Hypoxia reaches oxygen levels as low as 0.1 kPa at depths within the crabs vertical range. Crabs maintain aerobic me- Zooplankton tabolism to a critical PO2 of ~0.27 ± 0.2 kPa (10 °C), in part by increasing ventilation as oxygen declines. At Hypometabolism subcritical oxygen levels, they enhance anaerobic ATP production slightly as indicated by modest increases in Vertical migration lactate levels. However, hypoxia tolerance is primarily mediated via a pronounced suppression of aerobic me- tabolism (~70%). Metabolic suppression is achieved, primarily, via reduced protein synthesis, which is a major sink for metabolic energy. Posttranslational modifications on histone H3 suggest a condensed chromatin state and, hence, decreased transcription. -

In total, 105 species of these parasites (~18% of all bopyrids) are documented from Recent squat lobsters and porcelain crabs in the superfamilies Chirostyloidea and Galatheoidea. Aside from one endoparasite, all the bopyrids reported herein belong to the branchially infesting subfamily Pseudioninae. Approximately 29% (67 of 233 species) of pseudionine species parasitize squat lobsters and 16% (38 of 233 species) parasitize porcelain crabs. -

Allogalathea (Decapoda: Galatheidae): a Monospecific Genus of Squat Lobster?
Zoological Journal of the Linnean Society, 2011, 162, 245–270. With 7 figures Allogalathea (Decapoda: Galatheidae): a monospecific genus of squat lobster? PATRICIA CABEZAS1*, ENRIQUE MACPHERSON2 and ANNIE MACHORDOM1 1Museo Nacional de Ciencias Naturales (CSIC), José Gutiérrez Abascal 2, 28006 Madrid, Spain 2Centro de Estudios Avanzados de Blanes (CSIC), Carr. Acc. Cala Sant Francesc 14, 17300 Blanes, Girona, Spain Received 8 March 2010; revised 14 June 2010; accepted for publication 16 June 2010 The genus Allogalathea was established by Baba in 1969 to include the well-known species Galathea elegans. This species is widely distributed across the Indo-West Pacific Ocean, and is characterized by living in close association with crinoids, and by its conspicuous coloration. Although the genus is considered monospecific, different colour patterns and discrete morphological variations mainly associated with the rostrum and chelipeds have been reported. These differences could point to cryptic species, thereby questioning Allogalathea as a monotypic taxon. To address this issue, we sequenced the mitochondrial cytochrome oxidase I (COI; 658 bp) and 16S rRNA (882 bp) genes and the nuclear gene phosphoenolpyruvate carboxykinase (PEPCK; 598 bp) in numerous specimens from eight different localities, and also examined their morphological characters. DNA sequences were analysed using maximum-parsimony, maximum-likelihood, and Bayesian approaches of phylogenetic inference. The resulting trees were combined with morphological evidence to test species boundaries. Our molecular data revealed four deeply divergent clades, which can be distinguished by subtle morphological differences in the spinulation and length- : breadth ratio of the P1 carpus, spinulation of the walking legs, and shape of the rostrum. Our findings indicated that Allogalathea elegans is in fact a species complex comprising four different species, which, although genetically very distinct, are morphologically very similar. -

Bourne fed.] North Pacific Workshop on stock assessment and management of invertebrates. Can. Spec. Publ. Fish. Aquat. Sci.92. Two species of squat lobsters, Cerv/mumdct johni. Porter, and Pleuroncodes monodon, Milne Edwards, family Galatheidae. are harvested commercially off Chile. A commercial fishery began by exploiting the first spe cies bur. has gradually shifted to harvesting the second. The fishery for Pleuroncodes began in 1966 off San Antonio {L. 33°3S"SJ but has gradually moved southward and now extends to Talcahuano (37°S). There are two possible explanations for this shift in fishing area; (1) increased fishing pressure, and (2) changes in the natural environment. Some support for the second explanation is seen by simultaneous changes observed in other species which may be due to cyclic changes in the environment. Data on the fishery has been collected from 1%b to the present from the area between Coquimbo (30°S) and Talcahuano by the Fisheries Development Institute of Chile (Instituto de Fomento Pesquero, IFOP) by monitoring the fleet at landing ports and from research surveys.
