FISCHTHAL AND J. D. THOMAS2 ABSTRACT: Seven new and two previously described species of digenetic trematodes in the family Ope- coelidae are reported from marine fishes from Ghana. A new genus Pedunculotrema is erected for two new species, P. ghanensis (type) from liognathid and P. capecoastensis from pomadasyid fishes. This genus is closest to Plagiopoms Stafford, 1904, and Pseudoplagioporus Yamaguti, 1938, differing signifi- cantly in having the acetabulum stalked; it also is close to Podocotyloides Yamaguti, 1934, differing in having a postoral circular muscle ring, diagonal testes with their levels overlapping, the seminal vesicle tripartite, and the ovary opposite the anterior testis. Other new species are: Poracanthium ghanensis from polynemid, carangid and rhinobatid fishes; Pseudopecoehis ghanensis from a sciaenid fish; Podo- cotijle tememis from a serranid fish; Podocotyloides chloroscombri from a carangid fish; Plagioporus gerridis from a liognathid fish. Previously described species are: Pseudopecoelus tortugae von Wicklen, 1946, from trichiurid and sciaenid fishes; Helicometrafasciata (Rudolphi, 1819) Odhner, 1902, from clinid, pomacentrid, sciaenid, lutjanid, gobiid and clupeid fishes. The trematodes of this report were killed in DATES: 12 January, 3 February 1966 (G. hot water, transferred immediately to Lavdow- decadactijlus, Cape Coast); 12, 19 January sky's FAA fixative for 24 hr, and then stored 1966 (P. quinquarius, Cape Coast). in 70% alcohol plus 3% glycerine; whole SPECIMENS: USNM Helm.

This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. In vitro cultivation of digeneans would aid the development of effective treatments and studies of the biology of the parasites. The goal of this study was to optimize culture conditions for the trematode, Gynaecotyla adunca. Metacercariae of the parasite from fiddler crabs, Uca pugnax, excysted in trypsin, were incubated overnight to permit fertilization, and were cultured in different conditions to find those that resulted in maximum worm longevity and egg production. When cultured in media lacking serum, worms lived longer in Hanks balanced salt solution and Dulbecco’s Modified Eagle medium/F-12 (DME/F-12) than in RPMI-1640 but produced the most eggs in DME/F-12. Worm longevity and egg production increased when worms were grown in DME/F-12 supplemented with 20% chicken, horse, or newborn calf serum but the greatest number of eggs was deposited in cultures containing horse or chicken serum.

  • The Molecular Phylogeny of the Digenean Family Opecoelidae Ozaki, 1925 and the Value of Morphological Characters, with the Erection of a New Subfamily
    © Institute of Parasitology, Biology Centre CAS Folia Parasitologica 2016, 63: 013 doi: 10.14411/fp.2016.013 http://folia.paru.cas.cz Research Article The molecular phylogeny of the digenean family Opecoelidae Ozaki, 1925 and the value of morphological characters, with the erection of a new subfamily Rodney A. Bray1, Thomas H. Cribb2, D. Timothy J. Littlewood1 and Andrea Waeschenbach1 1 Department of Life Sciences, Natural History Museum, Cromwell Road, London, UK; 2 School of Biological Sciences, The University of Queensland, St Lucia, Queensland, Australia Abstract: Large and small rDNA sequences of 41 species of the family Opecoelidae are utilised to produce phylogenetic inference trees, using brachycladioids and lepocreadioids as outgroups. Sequences were newly generated for 13 species. The resulting Bayesian trees show a monophyletic Opecoelidae. The earliest divergent group is the Stenakrinae, based on two species which are not of the type-genus. The next well-supported clade to diverge is constituted of three species of Helicometra Odhner, 1902. Based on this tree and the characters of the egg and uterus, a new subfamily, the Helicometrinae, is erected and defined to include the generaHelicometra , Helicometrina Linton, 1910 and Neohelicometra Siddiqi et Cable, 1960. The subfamily Opecoelinae is found to be monophyletic, but the Plagioporinae is paraphyletic. The single representative of the Opecoelininae (not of the type genus) is nested within a group of deep-sea ‘plagioporines’. The two representatives of the Opistholebetidae are embedded within a group of shallow-water ‘plagioporine’ species. The Opistholebetidae is reduced to subfamily status pro tem as its morphological and biological characteristics are distinctive.

  • New Insights Into the Phylogenetics and Population Structure of the Prairie Falcon (Falco Mexicanus) Jacqueline M
    Doyle et al. BMC Genomics (2018) 19:233 https://doi.org/10.1186/s12864-018-4615-z RESEARCH ARTICLE Open Access New insights into the phylogenetics and population structure of the prairie falcon (Falco mexicanus) Jacqueline M. Doyle1,2*, Douglas A. Bell3,4, Peter H. Bloom5, Gavin Emmons6, Amy Fesnock7, Todd E. Katzner8, Larry LaPré9, Kolbe Leonard10, Phillip SanMiguel11, Rick Westerman11 and J. Andrew DeWoody2,12 Abstract Background: Management requires a robust understanding of between- and within-species genetic variability, however such data are still lacking in many species. For example, although multiple population genetics studies of the peregrine falcon (Falco peregrinus) have been conducted, no similar studies have been done of the closely- related prairie falcon (F. mexicanus) and it is unclear how much genetic variation and population structure exists across the species’ range. Furthermore, the phylogenetic relationship of F. mexicanus relative to other falcon species is contested. We utilized a genomics approach (i.e., genome sequencing and assembly followed by single nucleotide polymorphism genotyping) to rapidly address these gaps in knowledge. Results: We sequenced the genome of a single female prairie falcon and generated a 1.17 Gb (gigabases) draft genome assembly. We generated maximum likelihood phylogenetic trees using complete mitochondrial genomes as well as nuclear protein-coding genes. This process provided evidence that F. mexicanus is an outgroup to the clade that includes the peregrine falcon and members of the subgenus Hierofalco. We annotated > 16,000 genes and almost 600,000 high-quality single nucleotide polymorphisms (SNPs) in the nuclear genome, providing the raw material for a SNP assay design featuring > 140 gene-associated markers and a molecular-sexing marker.

Olsen and Thomas P. Hodgman An Abstract of the Thesis Presented in Partial Fulfillment of the Requirements for the Degree of Master of Science (in Ecology and Environmental Sciences) May 2017 Tidal marshes represent one of the most productive natural systems on the globe, but because they are so physiologically stressful, they have low species richness. Consequently, tidal marsh communities are relatively homogenous across large spatial scales. Within saltmarshes, scale-dependent processes and patterns can be identified with the reduction of variation in community dynamics due to low species turnover. I conducted two studies in tidal marshes along the northeastern U.S. coast to explore the abiotic and biotic factors that influence food-web dynamics and community structure. I explored the effect of temporal and spatial variables on community composition of tidal-marsh invertebrates.

A loss of natural enemies, such as parasites, is one mechanism proposed to contribute to that success. While several studies have shown NIS are initially less parasitized than native conspecifics, fewer studies have investigated whether parasite richness changes over time. Moreover, evaluating the role that parasites have in invaded communities requires not only an understanding of the parasite diversity of NIS but also the species with which they interact; yet parasite diversity in native species may be inadequately quantified. In our study, we examined parasite taxonomic richness, infection prevalence, and infection intensity in the invasive Asian shore crab Hemigrapsus sanguineus De Haan, 1835 and two native mud crabs (Panopeus herbstii Milne-Edwards, 1834 and Eurypanopeus depressus Smith, 1869) in estuarine and coastal communities along the east coast of the USA.

    LECTURE NNOTE ON FIS 201 (2Units) INTRODUCTION TO FISHERIES MANAGEMENT PREPARED BY DR (MRS) IKENWEIWE N. BOLATITO AQUACULTURE AND FISHERIES DEPARTMENT UNIVERSITY OF AGRICULTURE,ABEOKUTA 1 INTRODUCTION ICTHYOLOGY is the scientific study of fish. Fish, because of the possession of notochord belong to the phylum chordata. They are most numerous vertebrates. About 20,000 species are known to science, and compare to other classes, aves 98,600species and mammals 8600species, reptiles 6,000 spandamphibians 2,000species.Fish also in various shape and forms from the smallest niamoy17mmT.L the giant whale shark that measures 15m and heights 25 tonnes. Fish are poikilothermic cold blooded animals that live in aquatic environment Most fish , especially the recent species, have scales on their body and survive in aquatic environment by the use of gills for respiration. Another major characteristic of a typical fish is the presence of gill slits which cover the gills on the posterior. (1) FISH TAXONOMY. Everyone is at heart a taxonomist whether by virtue or necessity or because of mere curiosity. 1. To know/identify the difference component in a fish population. That is to name and arrange. 2. To study the population dynamics in a population. (Number of each species in a population.) 3. Important in fish culture propagation – to know the species of fish that is most suitable for culture. 4. To exchange information to people in other parts of the world living known that both are dealing on the same species. 5. Reduce confusion as same Latin word generally acceptable worldwide are used while vernacular names differ form one location to another.
