Within-population variation in prevalence and lineage distribution of avian malaria in blue tits, Cyanistes caeruleus [PDF]

open access: yes
The development of molecular genetic screening techniques for avian blood parasites has revealed many novel aspects of their ecology, including greatly elevated diversity and complex host–parasite relationships.

Out with the Old and in with the New: A Comparison Between Molecular and Traditional Techniques to Identify Parasitized Birds [PDF]

open access: yes, 2012
Traditionally, the identification of blood parasites has been based on visual examination of blood smears. This approach depends on individual expertise in making blood smears and identifying parasites, which can vary widely from person to person. Recent

The evolutionary ecology of Leucocytozoon blood parasites of birds

open access: yes, 2009
Parasites can impose fitness effects on host populations: there may be seasonal and geographic variation in the interaction as well as over a longer time scale, host-parasite cospeciation.

Surto de malária por Haemoproteus columbae em pombos An outbreak of malaria by Haemoproteus columbae in pigeons

open access: yesArquivo Brasileiro de Medicina Veterinária e Zootecnia, 2001
Relata-se um surto de malária por Haemoproteus columbae em pombos-correio (Columba livia), caracterizado por um quadro agudo com mortalidade de 3% ao dia em aves de aspecto saudável ou crônico com prostração e fraqueza. O exame clínico das aves doentes evidenciou sinusite e conjuntivite e à necropsia traqueíte hemorrágica, aerossaculite, esplenomegalia,

Egy összetett szignalizációs mechanizmus: a madárének lokális, regionális és evolúciós mintázatai = Bird song as a multiple functioning sexual signal: patterns on individual, population and regional levels [PDF]

open access: yes, 2009
Tervezett vizsgálataink célja egy komplex, ivarilag szelekctált szignál, a madárének funkcionális kapcsolatrendszereinek felderítése volt. Különböző szinteken, egyedektől a poulációs szinten keresztül a fajok közötti kapcsolatokig vizsgáltuk a szignál ...

Characterization of Haemoproteus (Haemoproteus) columbae genome: as a tool for evolutionary study of Haemosporida order

open access: yes, 2019
Research on malaria has focused during a long time on the parasites that infect humans.However, it is also true that most information about the biology of this parasites comes from experimental models. For this reason, this thesis focuses on a Haemosporida parasite closely related to the Plasmodium genus, which is the Haemoproteus parasites.
