Congresso Brasileiro Sobre Crustáceos (CBC)
The Crustacean Society (TCS) Summer Meeting


Tradition and Innovation:
Integrative Approaches to Crustacean Studies

S1: To Encourage Study on the Systematics and Biology of Aegla

The fascinating taxon Aegla is only distributed in six South American countries (Brazil, Chile, Argentina, Uruguay, Paraguay & Bolivia), and so has mostly been studied by Portuguese and Spanish speaking researchers. The joint CBC.TCS.2022 meeting is the perfect opportunity for communication between these Latin and South American scientists and the rest of the international community. The symposium organizers also think that international scientific congresses, like the joint CBC.TCS.2022 meeting, should be an important venue for young students and researchers or early career scientists to participate and share their knowledge.

The crustacean fisheries make up an important percentage to the global fishery market and play a key role on the ecosystems where they are found. Additionally, these fisheries have been considered as one of the most impacting activities to marine ecosystems, producing large amounts of discards and severe damage to benthic fauna. Additionally, most of the catch is originated from trawling fisheries with large oil burning engines. In order to deal with the ecosystem impacts caused by crustacean fisheries is vital to understand the role of crustaceans in trophic webs, as well as to identify the collateral damages of this practices and eventually to develop new technologies to reduce it. Among the possible solutions for mitigating the damage originated from shrimp fisheries, the adoption of Bycatch Reduction Devices (BRD’s) has been widely adopted.

Duration: 2 hours.

Globally, the subterranean fauna is dominated by arthropods, and not surprisingly, crustaceans in the classes Maxillopoda, Ostracoda, and especially Malacostraca make up the bulk of the aquatic subterranean fauna. For example, the Eurasian amphipod genus Niphargus consists of over 300 species, and the predominantly North American amphipod genus Stygobromus consists of over 150 species, although no surface species is known for either genus. Knowledge of the ecology of the surface taxa is crucial for understanding the factors contributing to the initial colonization of the subterranean water. Some crustacean taxa in South America and especially in Brazil consists of multiple surface and subterranean species, such as amphipods in the genus Hyalella and decapods in the genus Aegla, among others. The goal of this symposium is to bring together researchers who study the biology of surface or subterranean crustaceans or both to explore commonalities or specific differences among taxonomic groups that may shed light on forces contributing to the colonization of subterranean habitats and the evolutionary dynamics of these taxa in subterranean environments.

Duration: 4 hours.

Freshwater crayfish (Decapoda: Astacidea) encompass almost 700 species distributed worldwide, except in continental Africa and Antarctica. They can be found in several kinds of limnetic habitats, such as streams, lakes, wetlands, swamp forests and caves. In South American, several new endemic species have been discovered and described in the last years using traditional morphology and integrative taxonomy and also the development of behavioral and genetic studies. The advance of integrative studies of South American crayfish will contribute in the study of evolution of freshwater crayfish in the world. However, in this situation, the presence of alien crayfish in South America, especially in Brazil, brings new serious threaten for conservation of the native biodiversity and ecosystems. Present symposium will bring the newest information of integrative studies of Parastacidae in South America, taking into account systematics, population genetics, biogeography, distribution modelling, behavior, habitat characterization, conservation and alien crayfish species. This symposium will reveal all research developed with crayfish in South America and encourage new students to work in the field of Astacology.

Do we take mating dynamics into account in crustacean fisheries management?

Duration: 2 hours.

Decapod crustaceans show a remarkable diversity with regard to their reproductive strategies and the underlying anatomical structures. Thus, characters of decapod reproductive systems have always played an important role in resolving phylogenetic relationships within this group. The male copulatory systems that function in delivering sperm to the female can provide important taxonomic characters for the identification of species. However, especially gonopods often show structural and functional adaptations that are characteristic for certain higher-level taxa of decapods, and strongly correspond to the female structures that receive sperm. Within decapods, two very important reproductive traits have evolved in the female reproductive system. The first trait is sperm storage in specialized female structures. Sperm storage of any kind enables to uncouple the point in time of insemination (at mating) and the actual fertilization of ova (at spawning). While a range of decapod crustacean females have evolved sperm storage structures (e.g., Cambaridae, Nephropidae, Brachyura), a mode of internal fertilization has only evolved in Eubrachyura.
This main goal of this symposium is to compare the diverse modes of sperm transfer and storage among different groups of decapod crustaceans, and discuss the phylogenetic implications of the observed character states. Contributions on the reproductive systems of isopods are welcome as well, as they represent the only other group of crustaceans that exhibit sperm storage in specialized female structures and show a range of convergencies to decapods.

Using Functional Morphology to Understand Crayfish Behavior and Evolution

(West Liberty University (USA)

Duration: 2 hours.

Continuous swimming might enhance fitness because it makes finding a mate more likely. However, continuous swimming might also increase the likelihood of being spotted by a predator. Similarly, inhabiting burrows might protect the individual for the harshness of the outside environment. However, the individual might have to defend its’ burrow from competitors, thereby raising costs. These constant trade-offs between costs and benefits shape the behaviors and morphologies. Our goal with this symposium is to show examples of how behavioral ecology and evolutionary ecology might help us understand the diversity and the evolution of crustaceans. To do so, we will provide examples on: 1. How camouflage and color enhance survival in crustaceans, 2. How finding a mate may facilitate the evolution of extravagant behaviors and morphologies, 3. How fighting influences the evolution of claws. During our talks we will show how theory can be used to make broader inferences about evolution, while also demonstrating how such inferences helps us understanding the evolution of crustaceans.

Duration: 2 hours.

One of the last frontiers of human knowledge, the deep sea is an amazing and challenging environment. With temperatures around four degrees Celsius, extreme pressure, no sunlight and scarce feeding resources, it was once imagined as a homogeneous environment, almost without life. However, it proved to be highly variable, with many kinds of habitats such as mountains chains, trenches, abyssal plains, thermal vents, cold seeps, coral reefs and sponge gardens. A wide variety of life forms are living in these habitats, between them the crustaceans are one of the most diverse and abundant groups. Modern sampling and research techniques as remotely operated vehicles and molecular biology are allowing us to learn much more about the deep-sea Crustaceans. This symposium will cover aspects of diversity and evolution of crustaceans living in the deep sea, including systematic and genetic approaches. Come with us to discover more about this last frontier!

Pablo Agustín Collins

Duration: 2 hours.

Ecotoxicology is a field of science involving the investigation of the effects of pollutants on organisms and ecosystems. Historically, many studies of aquatic toxicology have been done with crustaceans, because of their ecological relevance, economic importance and sensitivity. This symposium will focus on the use of crustaceans as model organisms in aquatic toxicology, and will include discussions on their historical role as test-organisms use in standardized toxicity tests, their use as models in studies involving molecular, physiological, biochemical histopathological, behavioral effects (biomarkers). The main idea is to provide an overview of the use of crustaceans in aquatic toxicology, as well as discuss perspectives to the future.
