Tllc formcr inclltdes information on whcrc in thc bird the parasites arc fo~~nd,the distribution of the parasite species by continents, degree of host specificity, and life cycles (whether on fresh or salt water and lists of known intermediate and paratenic hosts). These data sets are used to sl~owhow the parasite faunas arc related to the biology of the birds. The aquatic existence of grebes and the widc range of prey taken by individ~~alsand spccies of grebes are reflected in tlic wide range of helminths infecting the birds (113 species ofdigencs, 86 ofccstodes, 13 of aca~nthocephalans,and 37 of nematodes, most ofwhich have aquatic lifc cycles). One family, one subFC~rnily(each with the exception ofa singlc spccies), several genera, and 104 spccics of'hclminths are considered grcbc specialists, as at-e most ofthe specics of cctoparasitcs. Of the well-studied species of grcbc hel~ni~itlispecialists, almost all have been found in more than one gl-cbc spccies and Inany rnorc in more tllan orlc grebc genus. This is believed I-elatedto tllc fact that even grebes adapted for taking particular kinds of prey will usually take Inany other kinds. Thrrs, where several species of grcbcs arc sympatric, thcrc is a considerable ovel-lap in diet and consequently, ovcrlap in the intermediate hosts ingested. On thc other hand, most of the ectoparasites appear to be confined to single grebe species. Grebes contain large 11urnbcrsof intestinal lielminths. In a study of these parasites of 91 grcbcs from the breeding grotmds in Alberta (Stock 1985), all were found i~~fectcd,with nr~ml~ersranging from 2 to 15 specics and 112 to 33,169 individuals, the majority (96 percent) of which were cestodes. Most grebes spcrld the breeding season on eutrophic bodies ol'watcl; which have an abundant supply ofkinds and individuals ospotcntial prey for the birds. More than half of the spccies of grebcs winter on salt water where a variety of hcl~nirlthswith salt-water intermediate 1.1ostscan infect the birds, bl~ttlnfor- tl~nately,very Pew grebes taken on salt-watcr habitats have been examined for p;~r;isites. Still other kinds of'helminths may be acquired on bodies of watcr along the birds' migration routes. Most of the helm- i~lthsthat are obtained on fresh waters presumably are lost shortly after the birds' arrival on salt watcr and vi~pII(~T,S(C. What causes these changeovers in unknown, but it is suggested that the n~cchanisrnsfor this are I-eversals of the salt gradient in thc intestines. Eared Grebes coming to the highly salinc Mono Lake 011 their molt migration after the breeding season presumably soon lose their Iielminth parasites. Grebes have a u~~iquchabit of swallowing their own feathers which form pellets containing other indigestible materials and, when cast, arc believed also to rid the stomach of nen~atodcsthat Seed on the grebes' food therc. A separate plug of feathers is lodged in thc pyloric outlet of'the stomach where it acts as a sieve preventing large pieces of iildigestiblc material from passing through the intestine. This is bclicved to reduce the likelihood olpa~.asitesbeing dislodged from the wall of thc gut. Grebcs arc the only birds that do not nest on land but regularly build floating nests of matel-ial taken from the water.

Box 56, Dunedin 9054, New Zealand; [email protected] * Correspondence: [email protected]; Tel.: +47-481-37-867 Abstract: Free-living species often receive greater conservation attention than the parasites they support, with parasite conservation often being hindered by a lack of parasite biodiversity knowl- edge. This study aimed to determine the current state of knowledge regarding parasites of the Southern Hemisphere freshwater fish family Galaxiidae, in order to identify knowledge gaps to focus future research attention. Specifically, we assessed how galaxiid–parasite knowledge differs among geographic regions in relation to research effort (i.e., number of studies or fish individuals examined, extent of tissue examination, taxonomic resolution), in addition to ecological traits known to influ- ence parasite richness. To date, ~50% of galaxiid species have been examined for parasites, though the majority of studies have focused on single parasite taxa rather than assessing the full diversity of macro- and microparasites. The highest number of parasites were observed from Argentinean galaxiids, and studies in all geographic regions were biased towards the highly abundant and most widely distributed galaxiid species, Galaxias maculatus.

  • RUNNING HEAD: Farrow-Aspects of the Life Cycle of Apharyngostrigea Pipientis
    RUNNING HEAD: Farrow-Aspects of the life cycle of Apharyngostrigea pipientis Aspects of the life cycle of Apharyngostrigea pipientis in Central Florida wetlands Abigail Farrow Florida Southern College RUNNING HEAD: Farrow-Aspects of the life cycle of Apharyngostrigea pipientis Abstract Apharyngostrigea pipientis (Trematoda: Strigeidae) is known to form metacercariae around the pericardium of anuran tadpoles in Michigan and other northern locations. Definitive hosts are thought to be wading birds, while the intermediate host is a freshwater snail. Apharyngostrigea pipientis is not commonly reported from Florida, yet we have found several populations of snails (Biopholaria havaensis) and tadpoles, primarily the Cuban treefrog (Osteopilus septentrionalis), to host this trematode. We used experimental infections to elucidate the transmission dynamics and development of A. pipientis inside the tadpole host. Surprisingly, we found two types (species?) of cercariae being shed from B. havaensis that enter Cuban treefrog tadpoles to form seemingly identical metacercariae. Further, both of these develop into metaceracariae inside the tadpoles over 5-7 days after wondering inside the host's body cavity as mesocercariae, and metacercariae are commonly concentrated around the pericardium cavity. However, they differ in entry mode, with one being ingested, whereas the other penetrates the skin. This project is ongoing. 1. Introduction The study of parasitology plays a vital role in understanding the foundation of communities in different ecosystems. Parasites have the ability to exploit their hosts, directly affecting the health of the organism and the environment. By having these abilities, it could mean a change in the way the organism contributes to and balances the overall ecosystem (Poulin, 1999).

Some recent contributions from our lab have attempted to help fill a previous void in that information. Here, we report, four taxa of ectoparasites and five helminth parasites from three species of owls in Oklahoma. They include two species of chewing lice (Strigiphilus syrnii and Kurodeia magna), two species of hippoboscid flies (Icosta americana and Ornithoica vicina), a trematode (Strigea elegans) and a cestode (Paruterina candelabraria) from barred owls (Strix varia), and three nematodes, Porrocaecum depressum from an eastern screech owl (Megascops asio), Capillaria sp. eggs from S. varia, and Capillaria tenuissima from a great horned owl (Bubo virginianus). With the exception of Capillaria sp. eggs and I. americana, all represent new state records for Oklahoma and extend our knowledge of the parasitic biota of owls of the state. to opportunistically examine raptors from the Introduction state and document new geographic records for their parasites in Oklahoma.

  • The Decline and Probable Extinction of the Colombian Grebe Podiceps Andinus
    Bird Conservation International (1993) 3:221-234 The decline and probable extinction of the Colombian Grebe Podiceps andinus J. FJELDSA Summary Searches were made for the Colombian Grebe Podiceps andinus in 1981 in the wetlands in the Eastern Andes of Colombia. The studies also included surveys of other waterbirds and recorded the general conditions of these wetlands, once the stronghold for waterbirds in the northern Andes. The Colombian Grebe was apparently last seen in 1977 in Lake Tota, and is probably extinct, although a flock may have been moving around outside Lake Tota and could have settled outside the former breeding area. The primary reason for the decline must be draining of wetlands and eutrophication and siltation which destroyed the open submergent Potamogeton vegetation, where this grebe may have been feeding on a large diversity of arthropods. Introduction of exotic fish and hunting may also have played a role. Durante 1981 se han realizado varias expedidones en busca de Podiceps andinus en las zonas hiimedas de los Andes Orientales de Colombia. Durante estos estudios tambien se censaron otras aves acuaticas y se tomaron notas sobre el estado general de estas zonas humedas, que en el pasado fueron el principal enclave para las aves acuaticas en los Andes del Norte. Aparentemente Podiceps andinus fue visto por ultima vez en 1977 en el Lago Tota, y esta probablemente extinguido, aunque podrfa haber un bando en las inmediaciones de dicho lago que se hay a establecido fuera de la antigua area de cria. La razon fundamental del declive debe ser el drenaje de las zonas humedas y la eutrofiz- acion y salinizacion que ha destruido la vegetation sumergida de Potamogeton, donde esta especie se alimentaba de una gran variedad de artropodos.

  • Critter Class Grebe
    Critter Class Grebe Animal Diversity Web - Pied bill grebe September 21, 2011 Here is a link to the bird we will discuss tonight http://www.youtube.com/watch?v=v1XAFo_uVgk MVK: We will discuss the Glebe but we can have fun too! LOL MVK: http://www.youtube.com/watch?v=rdxxZgxWPt8 Comment: Oh my, how beautiful that was. Comment: Beautiful birds, they can even walk on water!! Comment: So cool how they walk on water! Comment: What an interesting bird and dance! Comment: Hi MVK...Neat bird...quite the courtship. MVK: There are 22 species of the grebe - so not all are the beautiful black and white ones in the videos. They are the Clark's grebe. MVK: The BBC does some beautiful animal documentaries - they also do the Lily and Hope Black Bear series. Comment: Where are they found (besides Oregon!)? MVK: Well it isn't letting me save the range map. Critter Class – Grebe 1 9/21/2011 MVK: A grebe ( /ˈɡriːb/) is a member of the Podicipediformes order, a widely distributed order of freshwater diving birds, some of which visit the sea when migrating and in winter. This order contains only a single family, the Podicipedidae, containing 22 species in 6 extant genera. Per Wikipedia MVK: Becky - there are many different types of grebes. The pied bill grebe is found pretty much in all the US Comment: Beautiful and graceful birds! I've never senn one before. Anxious to learn! MVK: Grebes are small to medium-large in size, have lobed toes, and are excellent swimmers and divers.

  • Some Aspects of the Taxonomy, Biology, Possible Evolution and Biogeography of Nematodes of the Spirurine Genus Rhabdochona Raill
    DOI: 10.2478/s11686-010-0017-3 © W. Stefan´ski Institute of Parasitology, PAS Acta Parasitologica, 2010, 55(2), 144–160; ISSN 1230-2821 Some aspects of the taxonomy, biology, possible evolution and biogeography of nematodes of the spirurine genus Rhabdochona Railliet, 1916 (Rhabdochonidae, Thelazioidea) František Moravec* Institute of Parasitology, Biology Centre of the Academy of Sciences of the Czech Republic, Branišovská 31, 370 05 České Budějovice, Czech Republic Abstract At present the nematode genus Rhabdochona Railliet, 1916 (Rhabdochonidae) comprises 92 possibly valid species, mostly in- testinal parasites of freshwater fishes in all zoogeographical regions. Because of the absence of any phylogenetic studies using molecular methods in this nematode group, an attempt to evaluate affinities among these parasites and their zoogeography on the basis of morphological features and host-parasite relationships has been carried out. Only true definitive hosts should be considered for such evaluation. It appears that, during the evolution of Rhabdochona spp., there occur an increase in the num- ber of anterior prostomal teeth, loss of lateral alae, the right spicule attains a boat-like shape and a dorsal barb develops on its distal tip, and the distal tip of the left spicule attains gradually a more complex structure; the eggs with a smooth surface are considered to be more primitive. Nematodes of this genus most probably originated in the region of present southern Asia at the beginning of Tertiary. Closest to the initial type appear to be members of the subgenus Globochona Moravec, 1972, from which lineages leading to the subgenera Globochonoides Moravec, 1975, Rhabdochona Railliet, 1916 and Sinonema Moravec, 1975 can be derived.
