Polychaete diversity in the estuarine habitats of Terminos Lagoon, Southern Gulf of Mexico. Memoirs of Museum Victoria 71: 97–107. In order to establish the status of the biodiversity of the polychaete fauna inhabiting the soft bottoms in the largest lagoon-estuarine system from the southern end of the Gulf of Mexico, Terminos Lagoon, we collected and identified 3,398 specimens belonging to 119 species and 33 families of polychaetes. The soft bottom fauna was then compared with records of polychaetes collected in other habitats in the lagoon such as seagrass beds and mangroves. In all, 190 species from 34 families of polychaetes previously recorded there were taken into account. The families Nereididae (20 spp.), Spionidae (15 spp.) and Syllidae (14 spp.) were the most diverse. The soft bottom habitat has by far the largest number of species (119) followed by the seagrass beds and mangroves with 75 and 42 species respectively. Large spatial heterogeneity in polychaete composition was observed, as only 5% of the species (Melinna maculata, Capitella sp., Mediomastus californiensis, Schistomeringos rudolphii, Marphysa sanguinea, Alitta succinea, Diopatra cuprea, Scoloplos treadwelli, Prionospio heterobranchia and Scolelepis squamata) were widely distributed in the lagoon. The polychaete fauna living in the mangroves is quite similar to that from seagrasses and soft bottoms (R(ANOSIM) = 0.247 and 0.3 respectively), but the polychaetes in the seagrasses and soft bottoms are clearly different from each other (R(ANOSIM) = 0.622). The 119 polychaete species identified in this study represent a significant increase in the records of biodiversity recorded so far in Terminos Lagoon, while the total of 190 species recorded for the whole lagoon represents a larger number than any other recorded for an American tropical estuary.","PeriodicalId":53647,"journal":{"name":"Memoirs of Museum Victoria","volume":"10 1","pages":"97-107"},"PeriodicalIF":0.0,"publicationDate":"2014-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84852928","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A well-illustrated glossary supports the study of polychaete anatomy and systematics, as well as aiding species identification, a need that emerged within the shipping and aquaculture industries over recent decades. Sabellidae, Serpulidae and Spionidae are polychaete families that most often include species that are translocated globally through ship fouling, ballast water or aquaculture trade. Accurate identifications are crucial since these translocations have significant ecological and commercial implications and also for phylogenetic and other biological studies. Using digital illustrations of specimens (deposited predominantly at the Australian Museum in Sydney), a glossary has been developed for these three families with the aim of standardising terminologies. Complete-focus images were generated with Helicon Focus 5.3 Pro software from multiple image layers. The definitions have been explained specific to families and illustrated with these images, thus creating the first comprehensive, digitally illustrated glossary of polychaete terminology.","PeriodicalId":53647,"journal":{"name":"Memoirs of Museum Victoria","volume":"1955 1","pages":"327-342"},"PeriodicalIF":0.0,"publicationDate":"2014-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91271348","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Shallow-water polychaete assemblages in the northwestern Mediterranean Sea and its possible use in the evaluation of good environmental state. Memoirs of Museum Victoria 71: 289–301. Forty-four shore-normal transects along the Northwestern Mediterranean coast between the mouth of the Rhone River (France) and Valencia City (Spain) were sampled during the REDIT-I (September 1998, [R1]) and REDIT-II (December 1999, [R2]) campaigns. Polychaete distribution patterns on shallow littoral fine sands (10 to 50 m water depths) were analyzed at a regional scale. A total of 359 species of polychaetes were identified which represents 38% of all polychaete species recorded in the western Mediterranean. Four main soft-bottom communities were identified from the samples in the area: Littoral Fine Sands, Littoral Sandy Mud, Terrigenous Coastal Mud and Detritic Sand. Predominantly sandy environments were characterized by Ditrupa arietina and Owenia fusiformis while Lumbrineris latreilli, Hilbigneris gracilis and Sternaspis scutata were numerically dominant in muddy environments. Biological diversity assessments at different temporal and spatial scales are required by the European Marine Strategy Framework Directive (2008/56/EC) in accordance with criteria and methodological standards of Good Environmental Status (GEnS).

A review of the occurrence and ecology of dense populations of Ditrupa arietina (Polychaeta: Serpulidae). Memoirs of Museum Victoria 71: 85–95. Dense populations of the free-living serpulid Ditrupa arietina were first recorded to the west and north of the Shetland Isles in the 1920s and have since been reported from the Celtic and North Seas, the Armorican shelf, the Mediterranean and the Azores. These dense populations (of many thousands per square metre) numerically dominate the benthic fauna, and the tubes provide sites of attachment for a range of other species. Vacated tubes are also occupied by other animals, and tube fragments can contribute significantly to biogenic carbonate sediments, both Recent and fossil. Dense Ditrupa populations have been the subject of detailed autecological research over the last 15 years, but in spite of the apparent ecological importance of the species, it is not reflected in the European Nature Information System (EUNIS) or other North-east (NE) Atlantic habitat classifications. This paper provides a synthesis of the environmental conditions where high densities of Ditrupa have been found, with new data from seabed samples and photos. Ditrupa appears to occupy different habitats in the NE Atlantic and the Mediterranean, and studies of its morphology and genetics are needed to determine if there is a taxonomic basis to this ecological separation. Although the evidence is sparse, it is concluded that, in the NE Atlantic, dense populations of Ditrupa are found in areas where the seabed is periodically disturbed by internal wave action. European and other habitat classification schemes require revision to reflect the areas of occurrence and benthic effects of internal waves.","PeriodicalId":53647,"journal":{"name":"Memoirs of Museum Victoria","volume":"326 1","pages":"85-95"},"PeriodicalIF":0.0,"publicationDate":"2014-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76901234","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Systematics, evolution and phylogeny of Annelida – a morphological perspective . Memoirs of Museum Victoria 71: 247–269. Annelida, traditionally divided into Polychaeta and Clitellata, is an evolutionary ancient and ecologically important group today usually considered to be monophyletic. However, there is a long debate regarding the in-group relationships as well as the direction of evolutionary changes within the group. This debate is correlated to the extraordinary evolutionary diversity of this group. Although annelids may generally be characterised as organisms with multiple repetitions of identically organised segments and usually bearing certain other characters such as a collagenous cuticle, chitinous chaetae or nuchal organs, none of these are present in every subgroup. This is even true for the annelid key character, segmentation. The first morphology-based cladistic analyses of polychaetes showed Polychaeta and Clitellata as sister groups. The former were divided into Scolecida and Palpata comprising Aciculata and Canalipalpata. This systematisation definitely replaced the old concept of dividing polychaetes into Errantia and Sedentaria, whereas the group Archiannelida had already been abandoned. The main critics came from a contradicting hypothesis relying on scenario based on plausibility considerations regarding Clitellata as highly derived annelids nesting within polychaetes and rendering the latter paraphyletic. In this hypothesis the absences of typical polychaete characters were regarded as losses rather than as primary absences. However, to date attempts to unambiguously identify the sister group of Clitellata on the basis of morphological characters have failed. Thus, two hypotheses on the last common annelid ancestor have been put forward either being an oligochaete-like burrowing animal or a parapodia-bearing epibenthic worm. These attempts to understand the major transitions in annelid evolution are reviewed and discussed in the light of new morphological evidence such as photoreceptor cell and eye evolution as well as the evolution of the nervous system and musculature. We also discuss the plausibility of these scenarios with regard to recent advances in molecular phylogenetic analyses.","PeriodicalId":53647,"journal":{"name":"Memoirs of Museum Victoria","volume":"7 1","pages":"247-269"},"PeriodicalIF":0.0,"publicationDate":"2014-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91077817","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Southwest Atlantic Ocean sand-reef building polychaete, Phragmatopoma lapidosa, was recently synonymised with Phragmatopoma caudata based on morphological characters. This study uses histochemical and ultrastructural procedures to describe oogenesis in Phragmatopoma caudata from the Southwest (SW) Atlantic and make a comparison with previously published data for the Northwest Atlantic (NW) forms. In the South American worms, the exposed ovary consists of simple groups of oogonia attached to blood vessels, unlike the NW Atlantic worms in which only the proliferative and previtellogenesis phases of the oocytes are associated with blood vessels. In SW Atlantic worms, the oocytes float in the coelom during the vitellogenic phase. We discovered several heterogeneous features (e.g., cell extensions, amoeboid cells, ovary capsule, active uptake of material from blood vessels and egg envelope) that can be used to distinguish between North and South Hemisphere populations of P. caudata. In light of the observed divergence between worms from these separated populations, our findings support reproductive plasticity.
