A Confusion of Crustaceans: Peracarida

The superorder Peracarida contains about 26,000 described species distributed in one fossil and 12 extant orders, representing 39% of all non-hexapod crustacean diversity. Peracarids are found in all environments, from terrestrial deserts to the depths of ocean trenches. They reach staggering diversity on land, in shallow-water tropical reefs, and in the Polar Oceans. The majority are marine, some exist only in groundwater or cave-waters, others live in freshwater and still others persist in hot springs at temperatures up to 40°C. Most are small, less than 1 cm long, although the largest reach 40 cm. The uniting characteristics of the group are that the young develop directly in a brood pouch on the female, and the presence of a lacinia mobilis. Dispersal in the group is dependent on swimming ability and passive means of transport such as rafting, rather than broad dispersal being a common part of the lifecycle through large scale larval transport. Most peracarids are free-living, but lifestyles found within the group include epibionts, commensals, obligatory parasites and even hyperparasites of other crustacean parasites. The proposed symposium will focus on broader aspects of peracarid biology. We aim to convene a broad diversity of peracarid scientists to explore all aspects of this exciting group of creatures and encourage abstracts from all disciplines.

Crustacean Evolutionary Physiology

This symposium will focus on the evolutionary physiology of the Crustacea, notably on osmotic and ionic regulation and metabolic, excretory and developmental physiology as driven by marine-freshwater transitions, and organismal, structural, biochemical and molecular adaptations to extant habitats. We begin by evaluating methodologies for establishing phylogenetic hypotheses and then examine procedures to map physiological characteristics onto such phylogenies, to estimate ancestral traits, to test adaptive hypotheses and to evaluate co-evolutionary processes. Speakers will then elaborate on specific topics and taxa that examine the principles of evolutionary physiology as illustrated by ion transport and metabolic and excretory mechanisms, use of molecular methods and markers, gene and protein expressions and pertinent comparative methodologies. Such issues, when integrated at different levels of structural organization, will disclose the mechanisms that have governed the patterns and processes of physiological evolution in extant crustaceans.

Crustacean Genomics

Applying state of the art sequencing technologies enables refined phylogenetic analyses, has many ecological applications including detection of endangered and invasive species through eDNA, and leads to a better understanding of gene functions, bridging the gap in our understanding of the intricate processes that translate the genome to phenome. Many researchers nowadays generate massive databases of RNA and DNA sequencing, although our understanding of gene functions lag behind. A uniform approach towards genome sequencing which is a grand challenge for crustaceans, as well as annotation procedures and access to these large databases by the general research community is warranted.

Crustacean Larval Diversity and Ecology

Crustaceans exhibit an amazing amount of diversity in their larval forms, an aspect of their biology that is responsible, at least in part, for their evolutionary success. Although all crustaceans exhibit a nauplius stage (not all of which are released as free larvae), development to adulthood for many groups includes several additional unique larval types. Some life cycles of crustaceans include gradual larval changes (anamorphic) whereas others exhibit abrupt changes (metamorphosis) including multiple larval types and transitions in habitat or host. Those taxa with metamorphosis include commercially (e.g., portunid crabs) and ecologically (e.g., parasites) important groups. The larvae of some taxa have been well documented, whereas many others remain understudied or have unknown relationships with adult forms (e.g., facetotectans). This symposium will focus on the diversity of crustacean larvae (widely conceived in terms of morphology, phylogenetic relationships, and biogeography) as well as their ecology and key roles in planktonic communities. In addition, aspects of larval development will be explored, including studies on crustaceans of importance in aquaculture and sustainable fisheries. We hope these discussions fill in gaps on the natural history of crustacean larvae and inspire new studies to more fully understand these critical life cycle stages.

Frontiers in Crustacean Biology: Asian Perspectives: Part III

Studies of crustacean biology in Asia has been remarkably expanded in the last decade. To promote interaction among carcinologists who have contributed to this development, Biology: Asian Perspectives was held in Tokyo, Japan in 2017, and Frontiers in Crustacean Biology: Asian Perspectives: Part II was held in Hong Kong in 2019. Unfortunately, the offline symposium was stopped after mid-year 2019 because of the COVID outbreak. To resume the encouragement of the study of crustacean biology in Asia with Asian-related fields, Frontiers in Crustacean Biology: Asian Perspectives: will continue as a symposium in ICC-10. The first speaker, A. Asakura of Japan, will introduce the history of this symposium, and then crustacean biology research in Asia will be present by M. Kodama of Japan, K.K. Chan of Taiwan, T. Kawai of Japan, J. Jung of Korea, C. McLay of New Zealand, with additionally joined speakers. The symposium invites, particularly early career TCS members in Asia. The advanced and recent fields of crustacean biology, systematics, conservation, ecology, physiology, morphology, and others in Asia with Asian-related areas are the main topics. The proceeding publication book of this symposium have been considered as the Advances in Crustacean Research series from CRC Press and Taylor & Francis Group, Series Editor: Ingo S. Wehrtmann. If you have the interest to join the symposium, contact the organizer of the symposium.

Marine Chelicerates

I would like to propose a symposium of marine chelicerates for the 10th International Crustacean Conference.  The symposium would be open to all aspects of the biology of the Pycnogonida and Xiphosura both extant and the fossil record.  While these animals are not crustaceans, their biology is closely related to the crustaceans.

Sexual Plasticity in Crustaceans

Crustaceans, of the most ancient arthropod groups in which sexual differentiation has been studied, exhibit a variety of reproductive strategies including gonochorism, hermaphroditism, intersexuality and even parthenogenesis and thus serving as excellent models to study sexual plasticity.

This hyper diverse group which contains over 65,000 species is inhabiting most aquatic niches and serving vital roles in the maintenance of the ecosystem’s health. They also serve as indicators for endocrine disruptors in polluted aquatic areas affecting sexual differentiation inflicting sexual bias in population structures. Moreover, since many species show sexually biased dimorphic growth patterns, the notable sexual plasticity of crustaceans often calls for the establishment of monosex aquaculture and mariculture biotechnologies. Therefore, in an era characterized by climate change and increased pollution which affects the stability of aquatic habitats, the field of sexual plasticity in crustaceans is of global interest at both ecological and food security aspects.

This symposium serves to communicate novel research that emphasizes the mechanism of sexual plasticity in crustaceans. Topics include life history studies, reproductive physiology, sexual differentiation, intersexuality, hermaphroditism, species conservation, population ecology and sex-manipulation-based biotechnologies for aquaculture, mariculture, and biocontrol. Other studies will be considered if they show direct relevance to sexual plasticity in crustaceans at the broad sense.

Science informs management of lobster in challenging times

We invite papers that share insights on how science informs the management of commercial and non-commercial fisheries for lobsters (and crustaceans more broadly). How can science inform management of stocks and the assessment of sustainable yield? Can we improve our knowledge of some of the key biological characteristics of lobsters including size at onset of maturity, fecundity, growth, aging, ontogenetic movement, natural mortality or their interaction with fishing such as vulnerability to potting (catchability)? What is the potential for culture of lobsters, including approaches that intercept the larval process and on-grow from larval or juvenile stages?  Can growth to market size be accelerated; can shell colour and morphology be manipulated to suit market preferences? What more can we learn about the interactions between lobsters and fishing and the habitats they live in and changes in the marine environment, including those influenced by climate change? Necrosis and shell conditions – what are the natural ‘triggers’ – are successful treatments possible?

Sharing the Data: reflections on building and maintaining a global alliance of data information systems

We invite our colleagues to share insights into the biogeography and distribution of crustaceans from around the world and all habitats. In a changing world, with increased evidence of modified horizontal and vertical distribution ranges, it is ever more important to capture geographic information. We encourage a discussion on data management and sharing that enable broad analyses of species range changes, responses to climate change.

UN Decade of Ocean Science for Sustainable Development : crustaceans helping us work together

Declared in 2019, the UN Decade of Ocean Science for Sustainable Development (2021–2030) promotes transformative multidisciplinary solutions to implement Sustainable Development Goal 14 – Life Below Water. Central to the Decade work programme is the creation of a new foundations across the science sector and communities to better manage the oceans. It is designed to increase mobilisation and activity across the ocean sector to support new, collaborative he partnerships and multidisciplinary solutions towards transformative ocean science. 

The NZ National Commission for UNESCO is responsible for leading Aotearoa New Zealand’s contribution to the Decade. Central to the National Commission’s Decade work is a multi-disciplinary approach that places indigenous knowledges (mātauranga Māori in Aotearoa NZ) at the core of our approach. Weaving knowledge systems together has generated a distinctive approach to undertaking science and research and how we collaborate with one another. Collaborating with indigenous researchers recognises the values of living rivers, coastlines and marine ecosystems including the contribution of blue economy. This special session will introduce provide different perspectives on our approach and also encourages wider research projects to present local or regional perspectives on how carcinology and ocean research connect with indigenous knowledge.
