While a single performance measure may give some insight, it may not be enough to ac - curately predict outcomes. Here, we used multiple measures of performance to explore potential mech- anisms behind species range shifts. We examined the thermal pattern for multiple measures of performance, including measures of aerobic metabolism and multi- ple as pects of escape speed, using the final larval stage (puerulus) of eastern rock lobster Sagmariasus verreauxi as a model species.

Decapod Crustacean Assemblages Off the West Coast of Central Italy (Western Mediterranean)
SCIENTIA MARINA 71(1) March 2007, 19-28, Barcelona (Spain) ISSN: 0214-8358 Decapod crustacean assemblages off the West coast of central Italy (western Mediterranean) EMANUELA FANELLI 1, FRANCESCO COLLOCA 2 and GIANDOMENICO ARDIZZONE 2 1 IAMC-CNR Marine Ecology Laboratory, Via G. da Verrazzano 17, 91014 Castellammare del Golfo (Trapani) Italy. E-mail: [email protected] 2 Department of Animal and Human Biology, University of Rome “la Sapienza”, V.le dell’Università 32, 00185 Rome, Italy. SUMMARY: Community structure and faunal composition of decapod crustaceans off the west coast of central Italy (west- ern Mediterranean) were investigated. Samples were collected during five trawl surveys carried out from June 1996 to June 2000 from 16 to 750 m depth. Multivariate analysis revealed the occurrence of five faunistic assemblages: 1) a strictly coastal community over sandy bottoms at depths <35 m; 2) a middle shelf community over sandy-muddy bottoms at depths between 50 and 100 m; 3) a slope edge community up to 200 m depth as a transition assemblage; 4) an upper slope community at depths between 200 and 450 m, and 5) a middle slope community at depths greater than 450 m. The existence of a shelf- slope edge transition is a characteristic of the western and central Mediterranean where a Leptometra phalangium facies is found in many areas at depths between 120 and 180 m. The brachyuran crab Liocarcinus depurator dominates the shallow muddy-sandy bottoms of the shelf, while Parapenaeus longirostris is the most abundant species from the shelf to the upper slope assemblage. -

STODDART Australian Museum, 6 College Street, Sydney NSW 2000, Australia ABSTRACT. Twenty-three species of deep-water lobsters in the families Nephropidae, Palinuridae, Polychelidae and Scyllaridae are recorded from the continental shelf and slope off eastern Australia. Ten species and two genera have not been previously recorded from Australia. These are Acanthacaris tenuimana, Projasus parkeri, Polycheles baccatus, P. euthrix, P. granulatus, Stereomastis andamanensis, S. helleri, S. sculpta, S. suhmi and Willemoesia bonaspei. The deep water lobster fauna of eastern Australia is compared with those of other Indo-Pacific areas. A key is given to all deep-water lobster species recorded from Australian waters.

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. -
The Utilization of Lobsters by Humans in the Mediterranean Basin from the Prehistoric Era to the Modern Era – an Interdisciplinary Short Review
Athens Journal of Mediterranean Studies- Volume 1, Issue 3 – Pages 223-234 The Utilization of Lobsters by Humans in the Mediterranean Basin from the Prehistoric Era to the Modern Era – An Interdisciplinary Short Review By Ehud Spanier The Mediterranean and Red Seas host a variety of clawed, spiny and slipper lobsters. Lobsters' utilization in ancient times varied, ranging from complete prohibition by the Jewish religion, to that of epicurean status in the Roman world. One of the earliest known illustrations of a spiny lobster was a wall carving in Egypt depicting the Queen Hatshepsut expedition to the Red Sea in the 15th century BC. Lobsters were known by the ancient Greeks and Romans as was expressed in art forms and writings. Lobsters also appeared in ancient mosaics and coins. The writings of naturalists and philosophers from the Roman-Hellenistic period, together with illustrative records indicate that lobsters were a popular food and there was considerable knowledge of their classification, biology and fisheries. The popularity of lobsters as gourmet food increased with time followed by an expansion of the scientific knowledge as well as over exploitation of these resources. Keywords: Antiquity, Biology, Fisheries, Lobsters, Mediterranean. Introduction A variety of edible lobsters, that are still commercially significant to human inhabitants today, are found in the water of the Mediterranean and adjacent Red Sea regions. This important marine resource includes at least two Mediterranean clawed lobsters (the European lobster, Homarus gammarus, and the Norway lobster, Nephrops norvegicus), five spiny lobsters (two in the Mediterranean: the common spiny lobster, Palinurus elephas, and the pink spiny lobster, P. -

Lobster Review
Seafood Watch Seafood Report American lobster Homarus americanus (Image © Monterey Bay Aquarium) Northeast Region Final Report February 2, 2006 Matthew Elliott Independent Consultant Monterey Bay Aquarium American Lobster About Seafood Watch® and the Seafood Reports Monterey Bay Aquarium’s Seafood Watch® program evaluates the ecological sustainability of wild-caught and farmed seafood commonly found in the United States marketplace. Seafood Watch® defines sustainable seafood as originating from sources, whether wild-caught or farmed, which can maintain or increase production in the long-term without jeopardizing the structure or function of affected ecosystems. Seafood Watch® makes its science-based recommendations available to the public in the form of regional pocket guides that can be downloaded from the Internet (seafoodwatch.org) or obtained from the Seafood Watch® program by emailing [email protected]. The program’s goals are to raise awareness of important ocean conservation issues and empower seafood consumers and businesses to make choices for healthy oceans. Each sustainability recommendation on the regional pocket guides is supported by a Seafood Report. Each report synthesizes and analyzes the most current ecological, fisheries and ecosystem science on a species, then evaluates this information against the program’s conservation ethic to arrive at a recommendation of “Best Choices,” “Good Alternatives,” or “Avoid.” The detailed evaluation methodology is available upon request. In producing the Seafood Reports, Seafood Watch® seeks out research published in academic, peer-reviewed journals whenever possible. Other sources of information include government technical publications, fishery management plans and supporting documents, and other scientific reviews of ecological sustainability. Seafood Watch® Fisheries Research Analysts also communicate regularly with ecologists, fisheries and aquaculture scientists, and members of industry and conservation organizations when evaluating fisheries and aquaculture practices. -
On the Structure and Mechanism of the Gastric Mill in Decapoda
ON THE STRUCTURE AND MECHANISM OF THE GASTRIC MILL IN DECAPODA. IV. The Structure of the Gastric Mill in Reptantous Macrura. By S. S. PATWARDHAN, M.Sc., Department of Zoology, College of Science, Nagpur. Received January 25, 1935. (Communicated by Prof. M. A. Moghe, M.A., M.Sc., r.z.s.) 1. Introduction. THE sub-order Macrura may be divided into two groups: (1) Reptantous Macrura, comprising crayfishes, lobsters and allied forms and characterised by possessing a dorsoventrally flattened body and a crawling and climbing mode of locomotion, and (2) Natantous Macrura comprising prawns and shrimps, characterised by possessing a laterally flattened body and a swimming mode of locomotion. The Reptantous Macrura are also characterised by the universal presence of a complex gastric mill and simple mandibles. In the present communication it is proposed to give a comparative account of the gastric mill in Reptantous Macrura. 2. Material and Method. The gastric mills of crayfish, Astacus fluviatilis, Palinurus and of many other lobsters have been already described in many text-books (Huxley, 1880; Powell, 1913) . The material at my disposal consists of six species obtained from various Biological Supplies Stations and represents all the tribes, excepting Eryonidea, and four families.
