Ungulate malaria parasites
Haemosporida parasites of even-toed ungulates are diverse and globally distributed, but since their discovery in 1913 their characterization has relied exclusively on microscopy-based descriptions. In order to bring molecular approaches to bear on the identity and evolutionary relationships of ungulate malaria parasites, we conducted Plasmodium cytb-specific nested PCR surveys using blood from ...
متن کاملWild Ungulate Surveys in Grassland Habitats:
Surveying grassland ungulates presents unique problems to the researcher. Appropriate statistical methods exist, but applying them in the field invariably requires ingenuity and compromise. I describe line-transect surveys I conducted of 3 plateau grassland species in Qinghai province, focusing on underlying statistical assumptions and specific measures I took to deal with each. I also suggest ...
متن کاملUngulate saliva inhibits a grass-endophyte mutualism.
Fungal endophytes modify plant-herbivore interactions by producing toxic alkaloids that deter herbivory. However, studies have neglected the direct effects herbivores may have on endophytes. Antifungal properties and signalling effectors in herbivore saliva suggest that evolutionary pressures may select for animals that mitigate the effects of endophyte-produced alkaloids. Here, we tested wheth...
متن کاملBiology of Porcine Parvovirus (Ungulate parvovirus 1)
Porcine parvovirus (PPV) is among the most important infectious agents causing infertility in pigs. Until recently, it was thought that the virus had low genetic variance, and that prevention of its harmful effect on pig fertility could be well-controlled by vaccination. However, at the beginning of the third millennium, field observations raised concerns about the effectiveness of the availabl...
متن کاملEvaluating prey switching in wolf-ungulate systems.
Wolf restoration has become a widely accepted conservation and management practice throughout North America and Europe, though the ecosystem effects of returning top carnivores remain both scientific and societal controversies. Mathematical models predicting and describing wolf-ungulate interactions are typically limited to the wolves' primary prey, with the potential for prey switching in wolf...
