AI Article Synopsis
- The study aimed to identify haemosporidian parasites in eared doves (Zenaida auriculata) in Brazil by capturing 211 doves and analyzing their blood.
- Through nested PCR and genetic analysis, the researchers found that 99.05% of the doves were infected, predominantly with Haemoproteus spp.
- This research marks the first molecular investigation of these parasites in eared doves in Brazil, revealing the presence of Haemoproteus multipigmentatus and Plasmodium spp. infections.
Article Abstract
The aim of this study was to verify the presence and identify the species of haemosporidian parasites in eared doves (Zenaida auriculata) in Brazil. Two hundred and eleven male and female eared doves were trap-captured in four different regions of Londrina city, in southern Brazil. Whole blood was collected in EDTA tubes through heart puncture after euthanasia in a CO2 chamber. A nested PCR targeting the mitochondrial cytochrome b gene (cyt b) of Haemoproteus spp./Plasmodium spp. was performed, followed by an enzymatic digestion to identify the genus. Phylogenetic trees were constructed to determine the closely related species. Out of 211 eared doves, 209 (99.05%) were positive for Haemoproteus spp. and/or Plasmodium spp. RFLP analysis showed that 72.72% (152/209) of eared doves were positive only for Haemoproteus spp., 6.22% (13/209) were positive only for Plasmodium spp., and 21.05% (44/209) of eared doves had mixed infections. Genetic analysis found four samples that were homologous with Haemoproteus multipigmentatus and one that was homologous with Plasmodium sp. This is the first molecular study of hemoparasites from eared doves in Brazil, and it is also the first description of H. multipigmentatus and Plasmodium spp. infection in eared doves in Brazil.

Throughout history, food has played a fundamental role in the development of societies. An understanding of the diets of different cultures and their impact on health can provide valuable insights into their lifestyle. The identification of the animal remains found within two vessels is reported and, in addition, an assessment of whether the diet and soil composition of the period may be associated with toxic elements was carried out.

Article Synopsis
- Birds at high latitudes, like the Eared Dove, have special brain cells that help them sense light and change their breeding behavior based on the seasons.
- The Eared Dove can breed all year and doesn’t follow the typical breeding cycles like other birds.
- Scientists found three different light-sensitive proteins in the Eared Dove's brain that change based on the season, showing how these birds adapt their breeding strategies.

Lead (Pb) is a metal that can produces irreversible damage in living organisms. Some studies had reported that Pb produces histophysiological alterations in the digestive system (mainly liver) of birds; however, the effect of this metal on small intestine has not been fully examined. Additionally, little information is available on Pb disturbances in native birds of South America.

Molting is an important process in which old and worn feathers are exchanged for new ones. Plumage color is determined by pigments such as carotenes, melanin and by the ultrastructure of the feather. The importance of plumage coloration has been widely studied in different groups of birds, generally at a particular time of the year.

Farmland birds can be exposed to neonicotinoids through the ingestion of treated unburied seeds and cotyledons. The aim of this study was to evaluate the avoidance of sorghum with imidacloprid, clothianidin or thiamethoxam, soybean with imidacloprid, and soybean cotyledons with imidacloprid or thiamethoxam on eared doves (Zenaida auriculata). Doves were fed with test food (untreated and neonicotinoid-treated sorghum, soybean or soybean cotyledons) and maintenance food (seed mix) for 3-5 days to study the repellency (primary repellency and conditioned aversion) and anorexia caused by neonicotinoid-treated food, followed by a 7-day period on maintenance food to study the persistence of the anorexic effect after neonicotinoid exposure.
