| gastrointestinal parasites in greater rheas (rhea americana) and lesser rheas (rhea pennata) from argentina. | few data exist on the parasites of ratites, especially from regions within their natural range. it is only recently that extensive studies on the parasites of ostriches (struthio camelus) have been published, mainly from european countries where commercial farming has expanded. two species of ratites are native in south america: the lesser rhea also known as darwin's rhea (rhea pennata) and the greater rhea (rhea americana). both species are considered near threatened by the iucn and are include ... | 2012 | 23305970 |
| identification, classification, and growth of moa chicks (aves: dinornithiformes) from the genus euryapteryx. | the analysis of growth in extinct organisms is difficult. the general lack of skeletal material from a range of developmental states precludes determination of growth characteristics. for new zealand's extinct moa we have available to us a selection of rare femora at different developmental stages that have allowed a preliminary determination of the early growth of this giant flightless bird. we use a combination of femora morphometrics, ancient dna, and isotope analysis to provide information o ... | 2014 | 24923666 |
| morphology of the nematode deletrocephalus dimidiatus diesing, 1851 from the rhea, rhea americana linnaeus, 1758, together with a key to species of deletrocephalinae. | the family deletrocephalidae consists of three species, from two genera: deletrocephalus dimidiatus, d. cesarpintoi and paradeletrocephalus minor, which differ from one another in terms of the buccal capsule structure, the dorsal ray from the male copulatory bursa and the length of the vagina in the female. all these species are parasites of the gastrointestinal tract of the rhea, rhea americana. only d. dimidiatus was reported to be a parasite of the other rhea species, darwin's rhea, r. pennat ... | 2017 | 27018816 |
| culicoides species composition and molecular identification of host blood meals at two zoos in the uk. | culicoides biting midges are biological vectors of arboviruses including bluetongue virus (btv), schmallenberg virus (sbv) and african horse sickness virus (ahsv). zoos are home to a wide range of 'at risk' exotic and native species of animals. these animals have a high value both in monetary terms, conservation significance and breeding potential. to understand the risk these viruses pose to zoo animals, it is necessary to characterise the culicoides fauna at zoos and determine which potential ... | 2020 | 32178710 |
