Abstract The digenetic trematode family Gorgocephalidae comprises just a few species, and the literature devoted to lineage consists of only handful reports. With one exception, all reports have been based on material collected in Indo-West Pacific, an expansive marine ecoregion stretching from east coast Africa Easter Island, Hawaii French Polynesia. We adult intramolluscan gorgocephalids kyphosid fishes littorinid gastropods several Australian localities, South Specimens Gorgocephalus...
Abstract Background The nematode phylum includes many species key to soil food webs with trophic behaviours extending from feeding on microbes macrofauna and plant roots. Among these, the parasitic cyst nematodes retain their eggs in protective cysts prolonging survival under harsh conditions. These nematodes, including those genus Heterodera , cause significant economic losses agricultural systems. Understanding of diversity ecology has expanded through application genomic research,...
The Umagillidae Wahl, represent a group of endosymbiotic Platyhelminthes which inhabit two disparate invertebrate host groups, the echinoderms and sipunculans. Sipunculan-inhabiting umagillids are morphologically distinct from those inhabiting have traditionally been placed in genus subfamily, Collastoma Dörler, Collastominae respectively. Although molecular data available for umagillid species echinoids holothurians, sipunculans yet to be evaluated with data. esotericum n. sp. sipunculan...
Mindfulness, an ancient spiritual practice, is becoming increasingly popular component of communication courses, training individuals to reserve judgment in their dealings with others. However, the effects mindfulness courses are not well researched. We compared students taking introductory course that included a (N=20) against control group equivalent without content (N=24). Both groups improved positive reappraisal tendencies following training; however, appeared differ how they positively...
We report on Scorpidotrema longistipes and two new species belonging to a genus: Holsworthotrema enboubal ichthys gen. et sp. nov. chaoderma These taxa are the first representatives of subfamily Stenakrinae included in molecular phylogenetic analyses Opecoelidae. They resolve among deep-sea + freshwater Plagioporinae (s.l.) clade, but exploit shallow-water marine fishes. Based phylogeny, ecology morphology, we reorganize this clade into four subfamilies: (s.s.) for taxa, as currently defined...
Abstract A species of Heterodera has been known to parasitise cereals in Australia since the 1930s. It caused significant yield losses across Australia’s cereal growing regions until resistance breeding largely brought it under control, although still occurs occasionally, especially South and Western Australia. Australian cyst nematode long considered represent avenae . However, 2002 name australis was proposed for nematode, as could be distinguished from all non-Australian populations H via...
Several studies have shown that the euryxenic trematode Derogenes varicus (Müller, 1784) represents a species complex. Four lineages been designated (DV1-4) with DV1 clade corresponding to D. sensu stricto. Herein, we investigate newly collected specimens of lato from Scandinavian and Arctic waters using integrative taxonomy. The trematodes were Melanogrammus aeglefinus, Eutrigla gurnardus, Trachinus draco, Merluccius merluccius off Atlantic coast Sweden Hippoglossoides platessoides...
Abstract The superfamily Pronocephaloidea Looss, 1899 comprises digeneans occurring in the gut and respiratory organs of fishes, turtles, marine iguanas, birds mammals. Although many life cycles are known for species Notocotylidae Lühe, 1909 maturing mammals, relatively few remaining pronocephaloid lineages. We report cercariae five from gastropods Queensland coast, Australia. From Lizard Island, northern Great Barrier Reef, we three cercariae, two Rhinoclavis vertagus (Cerithiidae) one...
Abstract Difficulties inherent in the morphological identification of cyst nematodes genus Heterodera Schmidt, 1871, an important lineage plant parasites, has led to broad adoption molecular methods for diagnosing and differentiating species. The pool publicly available sequence data grown significantly over past few decades, half all known species have been characterized using one or more markers commonly employed DNA barcoding (18S, internal transcribed spacer [ITS], 28S, coxI ). But how...
Abstract We describe Isorchis cannoni n. sp. from the rabbitfishes Siganus fuscescens (Houttuyn) and lineatus (Valenciennes) (Siganidae) collected off Heron Island, southern Great Barrier Reef, Australia and, using molecular data, demonstrate that ‘ Cercariae queenslandae II’ of Cannon (1978) gastropod Clypeomorus batillariaeformis Habe & Kosuge (Cerithiidae) is larval form this new species. The cercariae I . develop in rediae, encyst environment after emergence, are inferred to then be...
Derogenes varicus (Müller, 1784) is widely reported as a trematode with exceptionally low host specificity and wide, bipolar distribution. However, several recent studies have suggested that D. represents species complex based on molecular evidence, four genetic lineages (labeled "DV1-4") been designated within the complex. This possibility requires improved (ideally molecular) characterisation of specimens from type-host (Salmo salar) type-locality (off Denmark). During examination...
Haplorchis pumilio (Trematoda: Heterophyidae) has become widely established around the world because of multiple introductions its snail hosts, and flexible host requirements at second-intermediate definitive levels. Although exotic thiarid snails introduced into North American waters have been previously reported to harbor H. pumilio, metacercariae not from native fishes in continental USA. In this study artificially exposed cyprinids cercariae infected became with trematode, sometimes...
Abstract The ryegrass cyst nematode, Heterodera mani , is reported from Western Australia for the first time. Cysts were recovered soil samples collected on a broadacre cropping property near town of Esperance. production area dominated by cereal/oilseed rotation and species annual ( Lolium rigidum ) common weed issue in these paddocks. Morphometrics cysts second stage juveniles (J2s) Australian population consistent with data other reports this species. Sequences mitochondrial cytochrome c...
Abstract Emprostiotrema contains just 3 species: E. fusum , kuntzi and sigani . As adults, all species infect rabbitfishes (Siganidae: Siganus ). New collections from 11 of northern Australia, Indonesia, Caledonia, French Polynesia, Palau Japan enabled an exploration composition within this genus. Phylogenetic analyses demonstrate a deep distinction between 2 major clades; clade 1 comprises most the sequences specimens Australia as well those Japan, Caledonia single sequence Bali. In...

The Great Barrier Reef is the largest coral reef ecosystem on planet and supports a diverse community of marine fishes, as well organisms that parasitise them. Although digenetic trematodes fishes have been studied for over century, species richness diversity many trematode lineages yet to be explored. Trigonocephalotrema, gen. nov. proposed accommodate three new species, Trigonocephalotrema euclidi, sp. nov., T. hipparchi, sohcahtoa, parasitic in Naso Lacepède Zebrasoma Swainson...
