Contrasting the seasonal and elevational prevalence of generalist avian haemosporidia in co‐occurring host species [PDF]

Ecology and Evolution, 2020
Understanding the ecology and evolution of parasites is contingent on identifying the selection pressures they face across their infection landscape. Such a task is made challenging by the fact that these pressures will likely vary across time and space,

Prevalence and Genetic Diversity of Haemoproteus and Leucocytozoon in Raptors and Other Captive Birds at the National Zoological Garden in South Africa. [PDF]

Integr Zool
Captive birds at the National Zoological Garden in South Africa harbor diverse haemosporidian parasite species and lineages. This might compromise conservation efforts of threatened species. ABSTRACT Avian haemosporidian infections have been associated with disease outbreaks in zoos and rehabilitation centers globally. This study aimed to determine the

Blood Parasites and Wildlife: The Development of a Discipline. [PDF]

Integr Zool
Changes in our knowledge on blood parasite infections of wild animals in the last 30 years is reviewed with emphasis on taxonomy and phylogeny, impact of infections on fitness, and distribution of blood parasites. ABSTRACT In the last 30 years, the area of the study of parasitism caused by blood parasite infections on wildlife has suffered an ...

Use of Contaminated Habitat and Associated Selenium Uptake Mediate Haemosporidian Parasite Infections in Wild Passerine Birds. [PDF]

Ecol Evol
We conducted a community‐scale field study to evaluate whether trace element contaminants derived from coal combustion residuals and nuclear fission products alter the dynamics of haemosporidian blood parasites, dipteran vectors, and avian hosts in riparian and wetland habitats in South Carolina, USA.

Multiple host-switching of Haemosporidia parasites in bats - art. no. 157

, 2007
Background: There have been reported cases of host- switching in avian and lizard species of Plasmodium (Apicomplexa, Haemosporidia), as well as in those infecting different primate species. However, no evidence has previously been found for host-swapping between wild birds and mammals.

Prevalence and Diversity of Haemosporidian-Associated Matryoshka RNA Viruses in a Natural Population of Wild Birds. [PDF]

Ecol Evol
This study investigated the prevalence and diversity of Matryoshka RNA viruses (MaRNAV) in wild birds in the San Francisco Bay Area, California. Using RNA sequencing and RT‐PCR, we identified two novel MaRNAVs (MaRNAV‐5 and ‐6) associated with haemosporidian infections in passerines and raptors. These findings suggest a high prevalence of these viruses,

Impact of Subclinical Haemoproteus columbae Infection on Farmed Domestic Pigeons from Central Java (Yogyakarta), Indonesia, with Special Reference to Changes in the Hemogram

Pathogens, 2021
Pigeon haemoproteosis caused by Haemoproteus columbae (Apicomplexa: Haemosporida: Haemoproteidae) is globally prevalent in rock doves (Columba livia), although little is known regarding this disease in pigeons and doves in Indonesia.

Subtle stressors-Strong responses. Consistent negative effects of avian blood parasites on phenotypic and demographic traits across songbirds. [PDF]

J Anim Ecol
Avian blood parasites are widespread and often considered benign, yet mounting evidence suggests they subtly impair host traits. This meta‐analysis is timely and necessary to quantify their true impact across systems, challenging assumptions and highlighting overlooked consequences for fitness and population dynamics. Abstract Stressors that subtly yet

Amphibian Strategies Against Attacks by Flies: Host-Specificity and Threats. [PDF]

Ecol Evol
Species interactions between Diptera flies and amphibians play a significant role in tropical ecosystems, but their ecology and evolution remain understudied. This review explores the costs flies impose on amphibians, such as pathogen transmission and disruption of communication systems, and highlights the evolutionary strategies employed by both ...
