An Eclectic Overview of the SA Marine Science Community
A biologists’ personal overview of the SA Marine Science community and its outputs (2001-2006)*1 Mark J Gibbons, Department of Biodiversity and Conservation Biology, University of the Western Cape, Private Bag X17, Bellville 7535, South Africa. Email: [email protected] ABSTRACT I have analysed 1 295 of the outputs published by the South African Marine Science Community (SAMSC) in either peer-reviewed journals or as books/book chapters for the period 2001-2006, with a view to identifying trends in the field, summarizing institutional overlaps and assessing the demographic state-of-play. Although almost 70% of our outputs were published internationally, we published the bulk of our research in strictly marine science journals which suggests, perhaps, that we need to be thinking bigger. More than 22% of all outputs were led by International colleagues, and these were published in journals with a significantly higher Impact Factor than those led by local authors. Women led less than 25%, and persons from previously disadvantaged backgrounds led less than 10%, of all outputs: this needs monitoring, discussion and pro-active response by employers. Thirty-six authors (~95% male, ~97% white) were responsible for more than 50% of all outputs, which suggests that the field is not totally dominated by an ageing cohort. Despite the fact that the bulk of the SAMSC is centred in the SW Cape, our study areas are approximately equally spread around the coastline, though there is an obvious institutional bias to the geographical location of study sites. Globally-orientated studies were generally published in “better” outlets than locally-orientated work, and were more likely to be led by international colleagues. -

It is a hyperparasite that attaches itself to the dorsal face of isopods, themselves parasites in the buccal cavity of fishes. In this study, Cy. bellones was found on Ceratothoa parallela (Otto, 1828), a cymothoid isopod parasite of the sparid fish Boops boops off Algeria in the Mediterranean Sea. We provide, for the first time, molecular barcoding information of a hyperparasitic monogenean, the parasitic crustacean host, and the fish host, with COI sequences. -

Benvenuto, C and SC Weeks. 2020
--- Not for reuse or distribution --- 8 HERMAPHRODITISM AND GONOCHORISM Chiara Benvenuto and Stephen C. Weeks Abstract This chapter compares two sexual systems: hermaphroditism (each individual can produce gametes of either sex) and gonochorism (each individual produces gametes of only one of the two distinct sexes) in crustaceans. These two main sexual systems contain a variety of alternative modes of reproduction, which are of great interest from applied and theoretical perspectives. The chapter focuses on the description, prevalence, analysis, and interpretation of these sexual systems, centering on their evolutionary transitions. The ecological correlates of each reproduc- tive system are also explored. In particular, the prevalence of “unusual” (non- gonochoristic) re- productive strategies has been identified under low population densities and in unpredictable/ unstable environments, often linked to specific habitats or lifestyles (such as parasitism) and in colonizing species. Finally, population- level consequences of some sexual systems are consid- ered, especially in terms of sex ratios. The chapter aims to provide a broad and extensive overview of the evolution, adaptation, ecological constraints, and implications of the various reproductive modes in this extraordinarily successful group of organisms. INTRODUCTION 1 Historical Overview of the Study of Crustacean Reproduction Crustaceans are a very large and extraordinarily diverse group of mainly aquatic organisms, which play important roles in many ecosystems and are economically important. Thus, it is not surprising that numerous studies focus on their reproductive biology. However, these reviews mainly target specific groups such as decapods (Sagi et al. 1997, Chiba 2007, Mente 2008, Asakura 2009), caridean Reproductive Biology. Edited by Rickey D.

Welicky1,2* and Nico J. Smit1 Abstract Background: Anilocra capensis Leach, 1818 is the only named species of Anilocra Leach, 1818 from South Africa. Anilocra is a large genus (> 40 species) with high levels of diversity reported from the Caribbean and Indo-West Pacifc. Considering it is highly unlikely that all records of Anilocra from South Africa can be of a single species, the aim of this study was to better understand the diversity of Anilocra from this region and continent. Methods: To redescribe A. capensis, the syntypes of A. capensis and specimens recorded as A. capensis from Africa were borrowed from the Natural History Museum, London, UK, and The iZiko South African Museum, Cape Town. Newly collected fresh samples of A. capensis were collected from of Cape Town, South Africa. Morphological rede- scriptions of the syntypes, and other museum and fresh material were conducted. Fresh samples were used to charac- terise molecularly A. capensis using the mitochondrial cytochrome c oxidase subunit 1 gene (cox1). Results: Morphological analyses demonstrated that apart from A. capensis there are six Anilocra species new to sci- ence from Africa: Anilocra ianhudsoni n. sp., Anilocra bunkleywilliamsae n. sp., Anilocra paulsikkeli n. sp., Anilocra jovanasi n. sp., Anilocra angeladaviesae n. sp. and Anilocra hadfeldae n. sp. -

Parasites of Cartilaginous Fishes (Chondrichthyes) in South Africa – a Neglected Field of Marine Science
Institute of Parasitology, Biology Centre CAS Folia Parasitologica 2019, 66: 002 doi: 10.14411/fp.2019.002 http://folia.paru.cas.cz Research article Parasites of cartilaginous fishes (Chondrichthyes) in South Africa – a neglected field of marine science Bjoern C. Schaeffner and Nico J. Smit Water Research Group, Unit for Environmental Sciences and Management, Potchefstroom Campus, North-West University, Potchefstroom, South Africa Abstract: Southern Africa is considered one of the world’s ‘hotspots’ for the diversity of cartilaginous fishes (Chondrichthyes), with currently 204 reported species. Although numerous literature records and treatises on chondrichthyan fishes are available, a paucity of information exists on the biodiversity of their parasites. Chondrichthyan fishes are parasitised by several groups of protozoan and metazoan organisms that live either permanently or temporarily on and within their hosts. Reports of parasites infecting elasmobranchs and holocephalans in South Africa are sparse and information on most parasitic groups is fragmentary or entirely lacking. Parasitic copepods constitute the best-studied group with currently 70 described species (excluding undescribed species or nomina nuda) from chondrichthyans. Given the large number of chondrichthyan species present in southern Africa, it is expected that only a mere fraction of the parasite diversity has been discovered to date and numerous species await discovery and description. This review summarises information on all groups of parasites of chondrichthyan hosts and demonstrates the current knowledge of chondrichthyan parasites in South Africa. Checklists are provided displaying the host-parasite and parasite-host data known to date.
