Crustacean microcoprolites from the Upper Jurassic-lower cretaceous of the Neuqun Basin, Argentina: Systematics and biostratigraphic implications
(Polish Academy of Sciences. Institute of Paleobiology, 2010-06)
As a result of a microfacial study in the outer and middle ramp deposits of the Vaca Muerta Formation (lower Tithonian-upper Valanginian), four ichnotaxa of crustacean microcoprolites are described: Palaxius azulensis ...
Terrestrial crustacean breeding trace fossils from the Cretaceous of Patagonia (Argentina): Palaeobiological and evolutionary significance
(Elsevier Science, 2008-07)
The breeding trace fossils described herein along with the high density of Loloichnus baqueroensis in the Cretaceous formations of Patagonia suggest that crayfishes were soil engineers along the Cretaceous in southern South ...
First Report of viral Pathogens WSSV and IHHNV in Argentine Crustaceans
(Rosenstiel School of Marine and Atmospheric Science, 2010-01)
The pathogenic penaeid shrimp viruses white spot syndrome virus (wSSv) and infectious hypodermal and hematopoietic necrosis virus (IhhNv) are reported for the first time from Argentina. They both occurred in wild crustaceans ...
Digestive Physiology of Three Species of Decapoda Crustaceans of Argentina
(National Shellfisheries Association, 2013-12)
This review has the available information about the digestive physiology and morphology of three decapod species from Argentina: Pleoticus muelleri, Artemesia longinaris, and Neohelice granulata. The anatomy of the foregut ...
Influence of female size on offspring quality of the freshwater crayfish cherax quadricarinatus (Parastacidae: Decapoda)
(Crustacean Society, 2012-11)
Knowledge on maternal influences in offspring quality of decapod crustaceans is limited, especially for freshwater species. We investigated the effects of female body weight on production variables (actual fecundity, AF), ...
Neural organization of the second optic neuropil, the medulla, in the highly visual semiterrestrial crab Neohelice granulata
(Wiley-liss, Div John Wiley & Sons Inc, 2014-12)
Crustaceans are widely distributed and inhabit very different niches. Many of them are highly visual animals. Nevertheless, the neural composition of crustacean optic neuropils deeper than the lamina is mostly unknown. In ...
Vitellogenin and Lipovitellin from the prawn Macrobrachium borellii as hydrocarbon pollution biomarker
(Pergamon-Elsevier Science Ltd, 2012-08)
During reproduction vitellogenin (VTG) is transported to vitellogenic oocytes as a precursor of egg yolk lipovitellin (LV). As VTG synthesis is affected by environmental stressors, it is widely used as biomarker in endocrine ...
The opportunistic sense: The diet of Argentine hake Merluccius hubbsi reflects changes in prey availability
(Elsevier, 2019-03)
Changes in the abundance of some species in the San Matías Gulf (north Patagonia, Argentina) have been observed in recent years; in particular increases in crustaceans populations that could be influencing the trophic ...
Benthic decapod crustaceans associated with captures of Munida spp. (Decapoda: Anomura) in the Beagle Channel, Argentina
(Instituto de Ciencias del Mar Barcelona, 2004-12)
Los ensambles de crustáceos decápodos bentónicos en el Canal Beagle están dominados por los cangrejos galatheidos Munidasubrugosa y Munida gregaria . Este estudio trata sobre la distribución batimétrica y espacial, la ...
Pre-cooling effect on live transport of the Southern king crab, Lithodes santolla
(Elsevier Science, 2020-07)
Live transportation of subtidal crustaceans is mostly done in dry conditions. Lowered body temperatures optimizes survival since it reduces standard metabolism. In this study, we evaluated whether lowering water temperature ...
