Squat lobsters of the superfamilies Chirostyloidea and Galatheoidea are highly visible crustaceans on seamounts, continental margins, shelf environments, hydrothermal vents and coral reefs. About 1000 species are known. They frequently feature in deep-sea images taken by submersibles and are caught in large numbers by benthic dredges. Some species are so locally abundant that they form ‘red tides’. Others support a variety of important fisheries. ... [Information of the supplier]
The Trilobita is an impressively diverse extinct clade, familiar to schoolchildren and scientists alike, that captures the imagination for both aesthetic and scientific reasons. Their 300 million year history, deployed across perhaps 10,000 species, combined with a complex anatomy that can be coded for a broad array of quantitative and qualitative characters, has made them model citizens for applying phylogenetic methods to fossil organisms. Indeed, trilobites figured prominently in some of the earliest forays into cladistic analysis on American shores. One noteworthy aspect of phylogenetic studies incorporating trilobites is that they have not only been used to adduce questions about the nature of macroevolutionary patterns. They have also figured in studies about the processes that may have motivated these patterns. For instance, punctuated equilibria was developed based on information from trilobite phylogenies. Trilobite phylogenies have been used to explore how rates of evolution vary throughout the history of life, and consider the meaning of disparity and how it varies over evolutionary time and during the Cambrian radiation. They have also served as the basis for studies of the mechanisms of evolutionary radiations and mass extinctions. In addition, phylogenetic analyses of trilobites have served as the essential component data of various paleobiogeographic studies. Finally, they have even played a role in testing hypotheses in the burgeoning new field of evo-devo. During the last 20 years trilobite workers have made major strides towards reconstructing the trilobite “tree of life”. Prominent questions certainly still exist, paraphyletic groups like “Ptychopariida” continue to be a messy problem, and some orders are basically unknown from a phylogenetic perspective, yet significant progress has been made. We suspect that phylogenetic analyses of trilobites will continue apace. Some of these will take the form of studies that try to tease apart in greater detail ordinal and familial relationships. Others will focus on species-level phylogenies to gain insight not only into the nature of evolutionary patterns but also the processes that may generate these patterns. Moreover, detailed phylogenetic work at the species-level will be critical for unraveling the higher-level relationships among trilobites as many genera are undoubtedly not monophyletic. We find it encouraging and also salutary that such long extinct organisms can continue to capture the public’s imagination and spur scientific research. Once an evolutionary success story, they now serve as a potential model of how to integrate fossils and phylogeny in the service of shedding light on evolutionary patterns and processes. Here we present a classification of trilobites with a focus on groups that have been treated in phylogenetic studies. We present the classification and phylogenies herein not as the final word on evolutionary relationships, and readers are of course referred to the references in the bibliography for greater details. Instead, they are offered as a framework to build on for future studies and a unified resource and synthesis of what is available regarding cladistic studies of trilobites. ...

The 16th Conference of Crustacean Research (in the German language) will be presented by the University of Greifswald from March 14-17, 2013. [Editorial staff vifabio]
The mission of the Crustacean Society is to advance the study of all aspects of the biology of the Crustacea by promoting the exchange and dissemination of information throughout the world. The Crustacean Society publishes The Journal of Crustacean Biology. For the last 30 years we have published four issues per year. In 2012 we will be publishing six issues per year. The Crustacean Society would like to invite members and non-members alike to our meetings. We meet twice a year. In January we meet with The Society of Integrative and Comparative Biology and mid-year we have a meeting sometimes coordinated with other crustacean groups. Meetings are the place to network, bounce ideas around, and learn new things from other researchers. ... [Information of the supplier]
We are happy to inform you that the forthcoming Summer Meeting of The Crustacean Society (TCS), jointly hosted with the Latin American Association of Carcinology (ALCARCINUS), will be celebrated between Sunday 07 to Thursday 11 July 2013 in San José, Costa Rica, Central America. The event is open to any presentation on crustacean research, and we encourage colleagues to present results of their novel and innovating research. Currently, we have started to organize sessions on Sustainable Aquaculture, Molecular Phylogeny, Ecology, Reproduction & Development, Crustacean Fisheries, Behaviour and Conservation Biology in Crustaceans, Biology and Biodiversity of Peracarida and Biology and Biodiversity of the Branchiopoda. However, other topics are more than welcome. Contributions on crustaceans from any region of the world are welcome, and there is no geographical limitation to Latin America. This meeting, however, will have a “Latin American touch”: 1) the conference speakers invited by us will be from Latin America or have a long-standing collaboration with Latin America; and 2) although the preferred conference language will be English, we will open the possibility to present talks in Spanish, as long as the slides are in English. ...
