Estudo bioquímico comparativo da (Na+, K+)-ATPase branquial de Macrobrachium amazonicum (Heller, 1862) habitante de regiões continentais. 196p. Dissertação de Mestrado – Faculdade de Filosofia Ciências e Letras de Ribeirão Preto, Universidade de São Paulo, 2019. O camarão Macrobrachium amazonicum é um espécie diádroma, que apresenta uma ampla distribuição na América do Sul. Os camarões palemonídeos hiperregulam em água doce, sendo este processo energizado pela (Na+, K+)-ATPase e V(H+)-ATPase presentes no tecido branquial desses animais. Este trabalho teve como objetivo caracterizar e comparar as propriedades moleculares, bioquímicas e cinéticas da (Na+, K+)-ATPase e V(H+)-ATPase branquial de M. amazonicum de populações que habitam a Bacia do Rio da Prata (Paraná- Paraguai), proporcionando um melhor entendimento do processo osmorregulatório envolvido na invasão do ambiente dulcícola desta espécie. A (Na+, K+)-ATPase branquial de M. amazonicum recém capturado nos Rios Tietê e Grande apresentou atividade máxima de -1 -1 aproximadamente 130 nmol Pi min mg de proteína, representando cerca de 75% da atividade ATPase total. As propriedades cinéticas da (Na+, K+)-ATPase branquial destas duas populações apresentam grande semelhança entre si, porém são divergentes se comparadas a outras populações de M. amazonicum. De forma inédita, neste trabalho foi realizada a caracterização cinética da (Na+, K+)-ATPase branquial de M. amazonicum após a aclimatação em alta salinidade, utilizando os animais do Rio Tietê aclimatados em salinidade em 21 ‰S durante 10 dias. Essa aclimatação resultou na provocou a diminuição de aproximadamente 60% na atividade ATPase da (Na+, K+)-ATPase branquial (52,1 ± 1,9 nmol Pi min-1 mg-1 de proteína). A afinidade da enzima para os seus diferentes moduladores também foi alterada, sugerindo alterações na regulação da enzima com a aclimatação. Nos animais recém capturados a atividade insensível à ouabaína é composta principalmente pelas atividades da V(H+)-ATPase, Na+ e/ou K+-ATPase e F-ATPase, enquanto nos animais aclimatados ela é constituída pelas atividades da Ca2+-ATPase, Na+- e/ou K+-ATPase e F-ATPase. Atividade V(H+)-ATPase foi encontrada somente nos animais recém capturados. A V(H+)-ATPase branquial de M. amazonicum recém capturado apresentou uma atividade de 27,2 nmol Pi min- 1 mg-1 de proteína (Rio Tietê) e 16,7 nmol Pi min-1 mg-1 de proteína (Rio Grande). As afinidades aparentes da V(H+)-ATPase branquial de M. amazonicum de Rio Tietê para os seus moduladores foram inferiores aos valores encontrados para a população do Rio Grande. A eletroforese desnaturante (SDS-PAGE) da fração microsomal do tecido branquial de M. amazonicum sugere algumas diferenças de expressão proteica, sendo que a subunidade α da (Na+, K+)-ATPase apresentou apenas uma única banda imunorreativa (≈110kDa). A (Na+, K+)-ATPase localiza-se predominantemente ao longo do septo intralamelar nas brânquias e a aclimatação em alta salinidade durante 10 dias não causou mudanças nesta distribuição, sugerindo que a adaptação dos animais não depende da disponibilidade da enzima na membrana celular. A atividade da (Na+, K+)-ATPase branquial de M. amazonicum é alterada tanto pela presença do peptídeo FXYD2 exógeno, quanto pela fosforilação pelas proteínas quinases A e C endógenas em uma proteína da família FXYD presente na fração microsomal destes animais. Considerando que a alteração da atividade da (Na+, K+)-ATPase é dependente da salinidade, os resultados deste trabalho podem ser relevantes para uma melhor compreensão do processo osmorregulatório do M. amazonicum. ABSTRACT FABRI, L. M. A comparative biochemical study of the gill (Na+, K+)-ATPase from populations of Macrobrachium amazonicum (Heller, 1862) inhabiting continental waters. 196 pp. Dissertação de Mestrado. – Faculdade de Filosofia Ciências e Letras de Ribeirão Preto, Universidade de São Paulo, 2019. The freshwater shrimp Macrobrachium amazonicum is a diadromous species that has a wide distribution throughout South America. The palaemonid shrimps hyper-osmoregulate their hemolymph in fresh water, a process energized by the (Na+, K+)-ATPase and V(H+)- ATPase present in their gill tissue. In this study, we characterized and compared the molecular, biochemical and kinetic properties

Feeding habits of the prawns Processa edulis and Palaemon adspersus (Crustacea, Decapoda, Caridea) in the Alfacs Bay, Ebro Delta (NW Mediterranean).- The stomach contents of 147 Palaemon adspersus Rathke, and 102 Processa edulis (Risso) were analyzed. The frequency of occurrence method and the points method were used. The role of these species in the food web of Cymodocea nodosa meadows is defined. Results indicate that both species are predators of benthic invertebrates rather than scavengers or detritus feeders. The main food items varied according to species. The diet of Palaemon adspersus consisted almost entirely of crustaceans, molluscs, and plant material, with amphipods playing a major role. Processa edulis ate an almost equal amount of crustaceans and polychaetes. In P. adspersus, most dietary items differed according to size classes of prawn.

  • The First Amber Caridean Shrimp from Mexico Reveals the Ancient
    www.nature.com/scientificreports Corrected: Author Correction OPEN The frst amber caridean shrimp from Mexico reveals the ancient adaptation of the Palaemon to the Received: 25 February 2019 Accepted: 23 September 2019 mangrove estuary environment Published online: 29 October 2019 Bao-Jie Du1, Rui Chen2, Xin-Zheng Li3, Wen-Tao Tao1, Wen-Jun Bu1, Jin-Hua Xiao1 & Da-Wei Huang 1,2 The aquatic and semiaquatic invertebrates in fossiliferous amber have been reported, including taxa in a wide range of the subphylum Crustacea of Arthropoda. However, no caridean shrimp has been discovered so far in the world. The shrimp Palaemon aestuarius sp. nov. (Palaemonidae) preserved in amber from Chiapas, Mexico during Early Miocene (ca. 22.8 Ma) represents the frst and the oldest amber caridean species. This fnding suggests that the genus Palaemon has occupied Mexico at least since Early Miocene. In addition, the coexistence of the shrimp, a beetle larva, and a piece of residual leaf in the same amber supports the previous explanations for the Mexican amber depositional environment, in the tide-infuenced mangrove estuary region. Palaemonidae Rafnesque, 1815 is the largest shrimp family within the Caridea, with world-wide distribution1. It is now widely believed that it originated from the marine environment in the indo-western Pacifc warm waters, and has successfully adapted to non-marine environments, such as estuaries and limnic environments2–4. Palaemon Weber, 1795 is the second most species-rich genus besides the Macrobrachium Spence Bate, 1868 in the Palaemonidae4–6. Te 87 extant species of Palaemon are found in various habitats, such as marine, brackish and freshwater7,8.

    click for previous page - 108 - Interest to Fishery: Lindner (1957:21) described the present species together with Exhippolysmata oplophoroides as "in British Guiana the most abundant commercial forms", where they are either sold on the local market or exported in a dried state. In Surinam it is also of great commercial importance and next to Xiphopenaeus it is the most important species fished for locally; here too the dried product is exported, the fresh and also dried shrimp is sold at the local markets. In French Guiana, however, the species is "parfois utilisée dans l'alimentation, elle n'est que peu appréciée (Durand, 1961:33). In N.E.

  • Composition, Seasonality, and Life History of Decapod Shrimps in Great Bay, New Jersey
    20192019 NORTHEASTERNNortheastern Naturalist NATURALIST 26(4):817–834Vol. 26, No. 4 G. Schreiber, P.C. López-Duarte, and K.W. Able Composition, Seasonality, and Life History of Decapod Shrimps in Great Bay, New Jersey Giselle Schreiber1, Paola C. López-Duarte2, and Kenneth W. Able1,* Abstract - Shrimp are critical to estuarine food webs because they are a resource to eco- nomically and ecologically important fish and crabs, but also consume primary production and prey on larval fish and small invertebrates. Yet, we know little of their natural history. This study determined shrimp community composition, seasonality, and life histories by sampling the water column and benthos with plankton nets and benthic traps, respectively, in Great Bay, a relatively unaltered estuary in southern New Jersey. We identified 6 native (Crangon septemspinosa, Palaemon vulgaris, P. pugio, P. intermedius, Hippolyte pleura- canthus, and Gilvossius setimanus) and 1 non-native (P. macrodactylus) shrimp species. These results suggest that the estuary is home to a relatively diverse group of shrimp species that differ in the spatial and temporal use of the estuary and the adjacent inner shelf. Introduction Estuarine ecosystems are typically dynamic, especially in temperate waters, and comprised of a diverse community of resident and transient species. These can include several abundant shrimp species which are vital to the system as prey (Able and Fahay 2010), predators during different life stages (Ashelby et al. 2013, Bass et al. 2001, Locke et al. 2005, Taylor 2005, Taylor and Danila 2005, Taylor and Peck 2004), processors of plant production (Welsh 1975), and com- mercially important bait (Townes 1938).

Abstract Palaemon elegans, a new component of the Gulf of Gdańsk macrozoobenthos, colonised the southern Baltic coastal zone in the late 20th and early 21st century. Analysis of the stomach contents of P. elegans revealed 16 plant and animal taxa that these prawns had fed on. The principal dietary component was detritus, with a mean frequency of occurrence in stomachs of > 80%. The most frequently occurring plant components in the diet were algae from the genus Cladophora and the family Ectocarpaceae, while the most significant animal components were Harpacticoida, Chironomidae, Ostracoda and Gammarus spp. The results of the study show that the dietary composition of P. elegans differed significantly between stations and months. The foraging area consisted of two distinctive regions – the Inner Puck Bay, and the Outer Puck Bay together with the Dead Vistula River; two of the stations – Gdynia and Sopot – were distinct from all the others. However, no obvious seasonality in the food composition could be demonstrated. * This work was funded by a research grant N N304 264934 from the Polish Ministry of Education and Science for the period 2008–11.

Regions affected by upwelling show environmental characteristics that may change the distribution of the species. This study evaluated the influence of environmental factors on the spatiotemporal distribution of two caridean shrimps, Nematopalaemon schmitti and Exhippolysmata oplophoroides, in a region of the Brazilian coast affected by Cabo Frio upwelling. Shrimps were collected monthly from July 2010 through June 2011 off Macaé off the northern coast of Rio de Janeiro State, at six locations: three at 5 m, and the other three at 15 m depth.

  • Environmental Preferences of Crangon Crangon
    ENVIRONMENTAL PREFERENCES OF CRANGON CRANGON (LINNAEUS, 1758), PALAEMON ADSPERSUS RATHKE, 1837, AND PALAEMON ELEGANS RATHKE, 1837 IN THE LITTORAL ZONE OF THE GULF OF GDANSK´ BY EMILIA ŁAPINSKA´ 1) and ANNA SZANIAWSKA Institute of Oceanography, University of Gdansk,´ al. Marszałka Piłsudskiego 46, PL-81-378 Gdynia, Poland ABSTRACT This study concerns the environmental requirements of the shrimp, Crangon crangon,andthe prawns, Palaemon adspersus and Palaemon elegans, which occur in the Gulf of Gdansk.´ Specimens were sampled from the 0.5-1.0 m and 5.0-10.0 m depth layers in the southwestern part of the Gulf, near the seaside resort of Sopot, in 2002-2003. The dominant species was C. crangon,the largest concentrations of which were recorded at 5.0-10.0 m. Seasonal changes were observed in the composition of the population of these three species during the year. P. elegans, a relative newcomer to the Polish zone of the Baltic Sea, has occupied a vacant ecological niche (the 0.5-1.0 m depth zone) and in doing so, has avoided competition with the native C. crangon. In the littoral zone (0.5-1.0 m) off Sopot, and also off Hel and Gdynia, P. elegans occurred together with P. adspersus. The diverse requirements of these three species with respect to biotic (e.g., food) and abiotic factors (e.g., substrate, dissolved oxygen) enable them to coexist in the waters of the Gulf of Gdansk.´ RÉSUMÉ Cette étude concerne les exigences environnementales des crevettes Crangon crangon, Palaemon adspersus et Palaemon elegans, qui sont présentes dans le golfe de Gdansk.´ Les spécimens ont été récoltés à 0,5-1,0 m et 5,0-10,0 m de profondeur dans la partie sud-ouest du golfe, près de la station balnéaire de Sopot, en 2002-2003.
