Workshops Dates - April 2-3, 2022

Workshop 1: “Cephalopod macroecology and biogeography”

2-day workshop. Lead organizers: Christian Ibáñez and Rui Rosa

Synopsis: Several macroecological hypotheses have been postulated to describe large-scale diversity and body size patterns in several terrestrial and aquatic taxa, but the validity of them to cephalopods remain largely untested. The aim of this workshop is to update the current knowledge on large-scale diversity and body size patterns in cephalopods and test biogeographic and macroecological hypotheses. Day 1 will focus on presentations (10-15 minutes max.) given by participants to show new data on the distribution of cephalopods. Day 2 will consist on break-out theme groups to start drafting the different sections of the review paper and eventually to construct a world database, with a special focus on epipelagic and mesopelagic cephalopod fauna.

Workshop 2: “Collection, handling and care of cephalopod eggs and egg masses”

2-day workshop. Lead organizers: Roger Villanueva, Anne-Sophie Darmaillacq, Michael Kuba.

Synopsis: The aim of this workshop is to provide an overview in: methods to stimulate and increase spawning in laboratories, parental effects on embryo and hatchling quality; natural and artificial oocyte fertilization; egg collection and/or monitoring egg masses from the wild; environmental factors influencing embryonic development; incubation of eggs with and without maternal care; artificial incubation of eggs in laboratory; identification of different embryonic stages, egg pathologies; egg transport; factors related with premature hatching; characterization of competent hatchlings; hatchling variability; welfare, anaesthetics and humane killing of advanced embryos and hatchlings. Brief presentations during Day 1 and a general design during Day 2 to publish a multiauthor review on that subject, are planned.

Workshop 3: “The role of cephalopods as predators and prey: the relevance of cephalopod beaks in ecological studies”

2-day workshop. Lead organizers: José Xavier, Yves Cherel, Alexey Golikov, José Queirós, Catalina Perales-Raya, Rigoberto Rosas-Luis

Synopsis: Cephalopods play an important role in numerous marine ecosystems. Much information on their role comes from the diet of their natural predators, as numerous cephalopod species are difficult to catch using nets or other sampling methods. Through their mandibles (beaks), information can be obtained on size and mass but also on distribution, population dynamics, age, growth, reproduction, feeding ecology, behavior, spawning areas, post-spawning mortality, sexual dimorphism, in addition to cephalopod consumption by predators and both cephalopod and predator migrations. Such information has been used for example, in fisheries assessment and management and ecosystem models. The aim of this workshop is to review the latest developments and information on the use of cephalopod beaks in ecological studies and its applications. Day 1 will focus on presentations (10-15 minutes max.) given by participants to generate discussion for the definition of the general structure of a review research paper on the topic. Day 2 will consist on break-out theme groups to start drafting the different sections of the review paper. The workshop will end with a plenary meeting will all workshop participants to establish deadlines and possible journals.

Workshop 4: “Cephalopod genomics and evolution"

2-day workshop. Lead organizers: Oleg Simakov and Caroline Albertin

Synopsis: The two-day workshop aims to bring together researchers working in the various emerging fields of cephalopod -omics and evolution. Building on previous workshops and interactions, the aim of this in-person event will be to consolidate and solidify exchanges of technical knowledge and protocols in the fields of cephalopod sequencing and evolutionary analyses, including but not limited to phylogenomics, (single cell) transcriptomics, regulatory genomics etc. A particular aim will be to discuss integration of those various aspects to begin understanding cephalopod gene regulation. First day will be dedicated to individual presentations, partitioned into thematic groups. Second day will discuss common problems faced by all cephalopod sequencing-related projects, emerging approaches and integration among different cephalopod systems. Together, we want to test the feasibility of combining those approaches to obtain a measure of how much (little) is known about cephalopod gene regulation. Finally, we will discuss future directions and meeting schedule, as well as eventual publications.

Workshop 5: “Cephalopod digestive tract”

2-day workshop. Lead organizers: Paul Andrews and Carlos Rosas

Synopsis: This workshop will build on the “The Digestive Tract of Cephalopods: the interface between ecology and physiology” meeting held in Cascais (Portugal) in 2015 with 17 papers published open access in Frontiers in Invertebrate Physiology (https://www.frontiersin.org/research-topics/5277/the-digestive-tract-of-cephalopods-at-the-interface-between-physiology-and-ecology#articles).
Now this workshop will review progress over the last 6 years on aspects of research covered at the previous meeting and will discuss newly emergent topics. This workshop will be of particular relevance to those interested in the basic science aspects of the cephalopod digestive tract as well as more applied aspects relating to aquaculture, welfare and ecology.

The structure of the workshop will be a framework of 4-6 review lectures (~30mins) setting the scene for “free”, shorter presentations (~15mins), with an emphasis on time for discussion. We wish to encourage participation from early career researchers.

Amongst the main topics which we hope to include in this workshop on the “Cephalopod Digestive Tract “are: Feeding strategies and behaviour; Novel insights into the morphology and physiological control of the digestive tract;  Contribution of genomics to studying the digestive tract functionality and control; Aquaculture and feeding Do the nutritional requirements change throughout the life cycle: paralarvae, juveniles and adults?; Microbiome, digestibility and immune response;  Environmental impacts on digestive tract functionality, e.g., temperature, microplastics, pH, parasites and poisons; Novel techniques and lessons from other aquatic species;  Digestive tract functionality as a welfare indicator.  We welcome suggestions for other topics.

Breakout sessions will be used for a discussion of key research questions and priorities to draft a consensus paper for publication. Additionally, the possibility of building a research consortium aimed at facilitating grant applications will be discussed. Publication of presentations is being explored.
