| genotyping of cryptosporidium spp. from free-living wild birds from brazil. | in wild and domestic birds, cryptosporidiosis is often associated with infections by cryptosporidium galli, cryptosporidium baileyi and cryptosporidium meleagridis. in addition to these species, a number of avian cryptosporidium species yet to be fully characterized are commonly found among exotic and wild avian isolates. the present study aimed to detect and identify samples of cryptosporidium spp. from free-living wild birds, in order to contribute to the knowledge of the variability of this p ... | 2010 | 21035268 |
| [relationship between biomass and parasite density of mediorhynchus emberizae (acanthocephala: gigantorhynchidae) parasites of paroaria dominicana (passeriformes: emberizidae) of the state of bahia, brazil]. | during the study of the metazoan parasites of paroaria dominicana (linnaeus, 1758), eight infrapopulations of mediorhynchus emberizae (rudolphi, 1819), were collected in the medium third of the small intestine, with parasite intensities ranging from one to ten specimens. differences among the average values of the biomass, volume of the eggs, volume of the testicles and the parasite density of the infrapopulations were statistically tested in order to detect variations of these parameters in fun ... | 2008 | 18823583 |
| [quantitative and morfometrical aspects in infrapopulations of platynosomum illiciens (trematoda: dicrocoeliidae) in paroaria dominicana (passeriformes: emberizidae) from the state of bahia, brazil]. | during the study of the metazoan parasites of paroaria dominicana linnaeus, 1758 (passeriformes), four infrapopulations of platynosomum illiciens (brown, 1901) (trematoda), parasitic in the liver ducts were collected, with intensity of infection 10, 11, 18 and 36 specimens respectively. differences between the means of morphometrical values and the total number of eggs were statistically tested. the liver weigh were not significantly correlated with avian total weigh and length, and with the tot ... | 2008 | 18373892 |
| ethno-ornithology and conservation of wild birds in the semi-arid caatinga of northeastern brazil. | the utilization of birds as pets has been recognized as one of the principal threats to global avifauna. most of the information about the use and sale of birds as pets has been limited to areas of high biodiversity and whose impacts of anthropic actions have been widely broadcast internationally, for example for the amazon forest and forest remnants of southeast asia. the caatinga predominates in the semi-arid region of brazil, and is one of the semi-arid biomes with the greatest biological div ... | 2013 | 23445769 |
| frugivory and seed dispersal by birds in cereus jamacaru dc. ssp. jamacaru (cactaceae) in the caatinga of northeastern brazil. | studies of the dispersal modes of plants aid our understanding of the dynamics of resource and its availability for dispersal agents. the present work sought to characterize the fruiting patterns of the native caatinga (dryland) cactus cereus jamacaru, identify its principal dispersers, and evaluate the effects of seed passage through digestive tract of dispersers on its germination. cereus jamacaru present an annual fruiting pattern and fruiting peaks occurred during june/2009 and february/2010 ... | 2014 | 25055084 |
| development and characterization of 19 polymorphic microsatellite loci from the red-cowled cardinal (paroaria dominicana, passeriformes, aves) using next-generation sequencing. | the red-cowled cardinal (paroaria dominicana) is an endemic passerine of the caatinga biome in brazil, and is one of the most traded passerines in the country. illegal trade can have serious impacts on wild populations, such as reduced population sizes, the introduction of the species to areas outside their historical range or mixing individuals from different populations. microsatellites constitute an important tool for population genetics and forensics studies, and hold great potential to help ... | 2019 | 31218542 |
| understanding the motivations for keeping wild birds in the semi-arid region of brazil. | birds are kept as pets around the world, and bird-keeping is an ancient and widespread practice, constituting one of the main reasons for the decline of some species. in the semi-arid region of brazil, this practice is very common and continues despite being designated as illegal in recent decades. this study aimed to identify the species and families of songbirds used as pets in the semi-arid region of brazil, characterize the maintenance of the exploited species in captivity, and evaluate the ... | 2018 | 29891010 |
