Haemoproteus Coatneyi
''Haemoproteus coatneyi'' is a species of parasitic eukaryote that is found in the yellowhammer. Male yellowhammers with high levels of this parasite produced fewer offspring (there was no such effect for females), and tend to be less brightly coloured. The striking plumage of the male yellowhammer may therefore have arisen as a signal of fitness to breed. Yellowhammers infected with ''Haemoproteus ''Haemoproteus'' is a genus of alveolates that are parasitic in birds, reptiles and amphibians.

Eukaryote
Eukaryotes () are organisms whose cells have a nucleus. All animals, plants, fungi, and many unicellular organisms, are Eukaryotes. They belong to the group of organisms Eukaryota or Eukarya, which is one of the three domains of life. Bacteria and Archaea (both prokaryotes) make up the other two domains. The eukaryotes are usually now regarded as having emerged in the Archaea or as a sister of the Asgard archaea. This implies that there are only two domains of life, Bacteria and Archaea, with eukaryotes incorporated among archaea. Eukaryotes represent a small minority of the number of organisms, but, due to their generally much larger size, their collective global biomass is estimated to be about equal to that of prokaryotes. Eukaryotes emerged approximately 2.3–1.8 billion years ago, during the Proterozoic eon, likely as flagellated phagotrophs. Their name comes from the Greek εὖ (''eu'', "well" or "good") and κάρυον (''karyon'', "nut" or "kernel"). Euka ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yellowhammer
The yellowhammer (''Emberiza citrinella'') is a passerine bird in the bunting family that is native to Eurasia and has been introduced to New Zealand and Australia. Most European birds remain in the breeding range year-round, but the eastern subspecies is partially migratory, with much of the population wintering further south. The male yellowhammer has a bright yellow head, streaked brown back, chestnut rump, and yellow under parts. Other plumages are duller versions of the same pattern. The yellowhammer is common in open areas with some shrubs or trees, and forms small flocks in winter. Its song has a rhythm like "A little bit of bread and no cheese". The song is very similar to that of its closest relative, the pine bunting, with which it interbreeds. Breeding commences mainly in April and May, with the female building a lined cup nest in a concealed location on or near the ground. The three to five eggs are patterned with a mesh of fine dark lines, giving rise to the old ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haemoproteus
''Haemoproteus'' is a genus of alveolates that are parasitic in birds, reptiles and amphibians. Its name is derived from Greek: ''Haima'', "blood", and ''Proteus'', a sea god who had the power of assuming different shapes. The name ''Haemoproteus'' was first used in the description of '' H. columbae'' in the blood of the pigeon ''Columba livia'' by Kruse in 1890. This was also the first description of this genus. Two other genera — '' Halteridium'' and '' Simondia'' — are now considered to be synonyms of ''Haemoproteus''. The protozoa are intracellular parasites that infect the erythrocytes. They are transmitted by blood sucking insects including mosquitoes, biting midges (''Culicoides''), louse flies (''Hippoboscidae'') and horse-flies (" tabanids", "tabanid flies"). Infection with this genus is sometimes known as pseudomalaria because of the parasites' similarities with ''Plasmodium'' species. Within the genus there are at least 173 species, 5 varieties and 1 subspecies. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haemosporida
The Haemosporida (sometimes called Haemospororida) are an order of intraerythrocytic parasitic alveolates. Taxonomy Over 500 species are in this order, organised into four families: the Garniidae, the Haemoproteidae, the Leucocytozoidae, and the Plasmodiidae. The majority of the species lie within three genera: ''Haemoproteus'', ''Leucocytozoon'', and ''Plasmodium''. The Haemoproteidae and the Plasmodiidae both produce pigment. These families have been placed in the suborder Laveraniina. Neither the Haemoproteidae nor the Leucocytozoidae have an asexual cycle in the peripheral blood. The Garniidae do not produce pigment, but do have an asexual cycle in the blood. The taxa in detail are: *Family Garniidae ** Genus '' Fallisia'' Lainson, Landau & Shaw 1974 *** Subgenus '' Fallisia'' *** Subgenus '' Plasmodioides'' Gabaldon, Ulloa and Zerpa 1985 ** Genus '' Garnia'' Lainson, Landau and Shaw 1971 ** Genus '' Progarnia'' Lainson 1995 *Family Haemoproteidae ** Genus '' Johnsprenti ...
