This study was designed to clarify the differences in the internal transcribed spacer (ITS) 1 and 5.8S nucleotide sequences of Moniezia expansa, M. benedeni and M. monardi isolated from ruminants in Japan and to determine their phylogenetic relationships. A 98% similarity in the 5.8S sequences was observed among the 3 Moniezia species, whereas many nucleotide indels and substitutions were obser...

Paradistomoidella cerberi n.g., n.sp. and Paracanthostomum cerberi from Cerberus rhynchops, Xenopharynx pyriformis and Allopharynx mehrai from Ptyas korros, Neopronocephalus orientalis from Geoemyda spinosa, and Duthiersia expansa from Varanus salvator are all reported from the area of Kuala Lumpur, Malaysia. Paradistomoidella cerberi most closely resembles members of Paradistomoides but is cha...

This study was carried out from November 2007 to March 2008 to identify the species and to determine the burden of small intestinal helminth parasites of sheep and goats slaughtered in Hawassa, southern Ethiopia. Intestines of 116 sheep and 71 goats were examined using standard procedures. Three species of parasites namely Trichostrongylus colubriformis, Bunostomum trigonocephalum and Moniezia ...

The timing of reproductive events is critical for fitness, and these events are often linked to weather and climate. Weather components are thought to influence the nesting behaviour of freshwater turtles, but to date there have been few quantitative studies and no comparative studies. We compared the environmental cues used by nesting Australian (Emydura macquarii and Chelodina expansa) and No...

Giant Amazon river turtles, Podocnemis expansa, are indigenous to the Amazon, Orinoco, and Essequibo River basins, and are distributed across nearly the entire width of the South American continent. Although once common, their large size, high fecundity, and gregarious nesting, made P. expansa especially vulnerable to over-harvesting for eggs and meat. Populations have been severely reduced or ...

UNLABELLED PREMISE OF THE STUDY Discovering missing ancestors is essential to understanding the evolutionary history of biodiversity on Earth. Evidence from extinct species can provide links for reconstructing intricate patterns of reticulate relationships among extant descendents. When fossils are unavailable and other evidence yields competing hypotheses to explain species ancestry, data f...

Given the previously documented importance of lipid concentration and composition in the successful cryopreservation of gorgonian corals, these parameters were assessed in oocytes of five species of scleractinian coral; Platygyra daedalea, Echinopora gemmacea, Echinophyllia aspera, Oxypora lacera and Astreopora expansa. Wax esters, phosphatidylethanolamine, phosphatidylcholine, and fatty acids ...

Background In some species, presence of multiple paternity, due to polyandric behavior have important consequences in the effective size of a population when compared to unique paternity, mainly when it is about endangered species[1]. Because the exacerbated exploitation of meat, guts and eggs as food by local communities, giant Amazonian river turtle (Podocnemis expansa) is at low risk/dependa...

A method is described to determine germination by blue-light excited red fluorescence in the positively photoblastic spores of Dryopteris paleacea Sw. This fluorescence is due to chlorophyll as evidenced from 1) a fluorescence-emission spectrum in vivo, where a bright fluorescence around 675 nm is obtained only in red light (R)-irradiated spores and 2) in vitro measurements with acetone extrac...

The present study was designed to explore the flavonoid contents and the radical scavenging activities of 50% ethanol extracts of leaves, stems, rachis and roots of Dryopteris erythrosora. The total flavonoid contents in various parts were determined as: stems > roots > rachis > leaves. All extracts from different parts of D. erythrosora showed strong bioactivities. The DPPH free radical scaven...
