The fish genera Gasterosteus, Hucho, Oxynoemacheilus, Salmo, and Schizothorax are examples of these groups among vertebrates, and the genera Magnibursatus (Trematoda), Margaritifera, Potomida, Microcondylaea, Leguminaia, Unio (Mollusca), and Phagocata (Planaria), among invertebrates. There is reason to believe that their ancestors spread to Europe through the Paratethys (or the proto-Paratethys basin that preceded it), where intense speciation took place and new genera of aquatic organisms arose. Some of the forms that originated in the Paratethys colonized the Mediterranean, and overwhelming data indicate that Citation: Artamonova, V.S.; Bolotov, representatives of the genera Salmo, Caspiomyzon, and Ecrobia migrated during the Miocene from I.N.; Vinarski, M.V.; Makhrov, A.A. -
Glycymeris Longior (Sowerby, 1832) Clam at the Southern Edge of Its Distribution (Argentine Sea) Lucas H
Gimenez et al. Helgol Mar Res (2020) 74:2 https://doi.org/10.1186/s10152-020-0534-x Helgoland Marine Research ORIGINAL ARTICLE Open Access Age and growth of Glycymeris longior (Sowerby, 1832) clam at the southern edge of its distribution (Argentine Sea) Lucas H. Gimenez1,2†, María del Socorro Doldan1,3,4*† , Paula C. Zaidman1,3,4 and Enrique M. Morsan1,3 Abstract Even though Glycymeris longior is a clam widely distributed in the SW Atlantic Ocean, little is known about its biology and life history. The present study assessed the periodicity of the internal growth increments of G. longior using thin shell sections. Each internal growth increment was composed of two alternating bands: a translucent band (light- coloured when viewed with transmitted light) and an opaque band (dark-coloured). Annual formation for each pair of bands was demonstrated. The formation of the annual growth increments was synchronous among individuals. Growth was determined from live clams collected at El Sótano, Argentine Sea (age range 29 to 69 years). Accord- ing to the growth model, G. longior grows fast during the frst 5 years of life and then growth= becomes slower in later years; individuals reached 50% and 90% of maximum size at 5 and 13 years of age, respectively. High variability was found in shell height for the frst 10 years: diferences up to 5–7 mm among individuals were registered for the frst 2 years of age, and up to 11 mm between the ages of 3 and 9 years. The growth performance index phi-prime (φ′) and the index of growth performance (P) of G. -

In Hungary, we recorded 5 known Myxobolus species (M. branchialis, M. caudatus, M. musculi, M. squamae, and M. tauricus) and described M. branchilateralis sp. n. In Portugal we recorded 6 Myxobolus species (M. branchialis, M. branchilateralis sp. n., M. cutanei, M. musculi, M. pfeifferi, and M. tauricus). Species found in the 2 habitats had similar spore morphology and only slight differences were observed in spore shape or measurements. All species showed a spe- cific tissue tropism and had a definite site selection. M. branchialis was recorded from the lamellae of the gills, large plasmodia of M. branchilateralis sp. n. developed at both sides of hemibranchia, M. squamae infected the scales, plasmodia of M. caudatus infected the scales and the fins, and M. tauricus were found in the fins and pin bones. In the muscle, 3 species, M. musculi, M. pfeifferi and M. tauricus were found; however they were found in distinct locations. -

Sargassum White Paper - Sargassum Outbreak in the Caribbean: Challenges, Opportunities and Regional Situation
UNITED NATIONS EP Distr. LIMITED UNEP(DEPI)/CAR WG.40/ INF8 30 October 2018 Original: ENGLISH Eighth Meeting of the Scientific and Technical Advisory Committee (STAC) to the Protocol Concerning Specially Protected Areas and Wildlife (SPAW) in the Wider Caribbean Region Panama City, Panama, 5 ‐ 7 December 2018 Sargassum White Paper - Sargassum Outbreak in the Caribbean: Challenges, Opportunities and Regional Situation For reasons of economy and the environment, Delegates are kindly requested to bring their copies of the Working and Information documents to the Meeting, and not to request additional copies. *This document has been reproduced without formal editing. Sargassum Outbreak in the Caribbean: Challenges, Opportunities & Regional Situations by the SPAW Sub-Programme at the UN Environment CEP Secretariat Conceptual background Pelagic Sargassum is a type of brown alga or seaweed that can form large floating mats that are often referred to as “golden tides”. Field surveys and satellite maps indicate that Sargassum blossoms naturally in the Tropical South Atlantic and in the North Atlantic including the Sargasso Sea, over an area spanning 2 million square miles in the warm waters of the Atlantic Ocean. In the last few years, there have been several episodes of unusual quantities of two species of Sargassum, S. natans and S. fluitans, reaching the coasts of many of the islands of the Caribbean Sea, and countries in South, Central, and North America. What appears to have been an unprecedented quantity of pelagic Sargassum reached Caribbean islands in the spring of 20111. Anomalous amounts of Sargassum also reached the coasts of Sierra Leone and the Gulf of Guinea in June 2011. -
Maximizing Offspring Production While Maintaining Genetic Diversity in Supplemental Breeding Programs of Highly Fecund Managed Species
Conservation in Practice Maximizing Offspring Production While Maintaining Genetic Diversity in Supplemental Breeding Programs of Highly Fecund Managed Species ANTHONY C. FIUMERA,∗‡ BRADY A. PORTER,∗§ GREG LOONEY,† MARJORIE A. ASMUSSEN,∗ AND JOHN C. AVISE∗ ∗Department of Genetics, University of Georgia, Athens, GA 30602, U.S.A. †Warm Spring Fish Technology Center, 5308 Spring Street, Warm Springs, GA 31830, U.S.A. Abstract: Supplemental breeding is an intensive population management strategy wherein adults are cap- tured from nature and spawned in controlled settings, and the resulting offspring are later released into the wild. To be effective, supplemental breeding programs require crossing strategies that maximize offspring production while maintaining genetic diversity within each supplemental year class. We used computer simula- tions to assess the efficacy of different mating designs to jointly maximize offspring production and maintain high levels of genetic diversity (as measured by the effective population size) under a variety of biological conditions particularly relevant to species with high fecundity and external fertilization, such as many fishes. We investigated four basic supplemental breeding designs involving either monogamous pairings or complete factorial designs (in which every female is mated to every male and vice versa), each with or without the added stipulation that all breeders contribute equally to the total reproductive output. In general, complete factorial designs that did not equalize parental contributions came closest to the goal of maximizing offspring production while still maintaining relatively large effective population sizes. Next, we estimated the effective population size of 10 different supplemental year classes within the breeding program of the robust redhorse (Moxostoma robustum). -
Early Stages of Fishes in the Western North Atlantic Ocean Volume
ISBN 0-9689167-4-x Early Stages of Fishes in the Western North Atlantic Ocean (Davis Strait, Southern Greenland and Flemish Cap to Cape Hatteras) Volume One Acipenseriformes through Syngnathiformes Michael P. Fahay ii Early Stages of Fishes in the Western North Atlantic Ocean iii Dedication This monograph is dedicated to those highly skilled larval fish illustrators whose talents and efforts have greatly facilitated the study of fish ontogeny. The works of many of those fine illustrators grace these pages. iv Early Stages of Fishes in the Western North Atlantic Ocean v Preface The contents of this monograph are a revision and update of an earlier atlas describing the eggs and larvae of western Atlantic marine fishes occurring between the Scotian Shelf and Cape Hatteras, North Carolina (Fahay, 1983). The three-fold increase in the total num- ber of species covered in the current compilation is the result of both a larger study area and a recent increase in published ontogenetic studies of fishes by many authors and students of the morphology of early stages of marine fishes. It is a tribute to the efforts of those authors that the ontogeny of greater than 70% of species known from the western North Atlantic Ocean is now well described. Michael Fahay 241 Sabino Road West Bath, Maine 04530 U.S.A. vi Acknowledgements I greatly appreciate the help provided by a number of very knowledgeable friends and colleagues dur- ing the preparation of this monograph. Jon Hare undertook a painstakingly critical review of the entire monograph, corrected omissions, inconsistencies, and errors of fact, and made suggestions which markedly improved its organization and presentation. -

Jennifer Mary Scott Date \\' 0:)..02 ABSTRACT The liminal is a condition of human existence which has been the concern of Japanese literature throughout its history, since it is an essential ingredient in the experience of crisis. This thesis examines Furui's contribution to this literature of the liminal (my term) - his careful and detailed psycho-socio-analytical studies of the late twentieth century mind in the liminal state. The introductory chapter begins with a brief overview of Furui 's writing and its place in contemporary Japanese literature, especially the literature of the liminal. I go on to outline the general theoretical approaches of the thesis. I base my argument on Turner's socio-anthropological interpretation of the tripartite structure of rites of passage, and focus on his view of the liminal as a threshold period or state in which normal social structures and hierarchies are replaced by the relatively unstructured egalitarianism of community (communitas). -
Jeremy Lyle Curriculum Vitae
JEREMY LYLE Biography Dr Jeremy Lyle is a Senior Research Fellow at the Institute for Marine and Antarctic Studies. He is interested in the field of fisheries ecology and biology with a particular focus on understanding fish population dynamics, the impacts of fishing on fish stocks and the characteristics of the recreational as well as commercial fishing sectors. After completing his PhD at the University of Liverpool (UK), Jeremy was employed as a fisheries scientist in the Northern Territory where he led a major initiative to develop a shark fishery off northern Australia. From there he joined the then Tasmanian Sea Fisheries Department and later the University of Tasmania. He has worked on a wide variety of commercial fisheries, including offshore trawl, small pelagics and coastal fisheries, as well as conducting recreational fishing surveys over many years. The primary focus of his research has been to understand the impacts of fishing on target and non-target species and provide the science required to support the sustainable management of the fish stocks. Jeremy's research interests include understanding the impacts of fishing activities on marine resources and how these can be developed and managed sustainably. In relation to recreational fisheries, he has a strong interest in the development of cost-effective survey methods as well as understanding the dynamics and drivers of fishing participation and their implications for resource sharing and management.

Phylogenetic Relationships of Freshwater Fishes of the Genus Capoeta (Actinopterygii, Cyprinidae) in Iran
Received: 3 May 2016 | Revised: 8 August 2016 | Accepted: 9 August 2016 DOI: 10.1002/ece3.2411 ORIGINAL RESEARCH Phylogenetic relationships of freshwater fishes of the genus Capoeta (Actinopterygii, Cyprinidae) in Iran Hamid Reza Ghanavi | Elena G. Gonzalez | Ignacio Doadrio Museo Nacional de Ciencias Naturales, Biodiversity and Evolutionary Abstract Biology Department, CSIC, Madrid, Spain The Middle East contains a great diversity of Capoeta species, but their taxonomy re- Correspondence mains poorly described. We used mitochondrial history to examine diversity of the Hamid Reza Ghanavi, Department of algae- scraping cyprinid Capoeta in Iran, applying the species- delimiting approaches Biology, Lund University, Lund, Sweden. Email: [email protected] General Mixed Yule- Coalescent (GMYC) and Poisson Tree Process (PTP) as well as haplotype network analyses. Using the BEAST program, we also examined temporal divergence patterns of Capoeta. The monophyly of the genus and the existence of three previously described main clades (Mesopotamian, Anatolian- Iranian, and Aralo- Caspian) were confirmed. However, the phylogeny proposed novel taxonomic findings within Capoeta. Results of GMYC, bPTP, and phylogenetic analyses were similar and suggested that species diversity in Iran is currently underestimated. At least four can- didate species, Capoeta sp4, Capoeta sp5, Capoeta sp6, and Capoeta sp7, are awaiting description. Capoeta capoeta comprises a species complex with distinct genetic line- ages. The divergence times of the three main Capoeta clades are estimated to have occurred around 15.6–12.4 Mya, consistent with a Mio- Pleistocene origin of the di- versity of Capoeta in Iran. The changes in Caspian Sea levels associated with climate fluctuations and geomorphological events such as the uplift of the Zagros and Alborz Mountains may account for the complex speciation patterns in Capoeta in Iran. -
