| Avian cryptosporidiosis has been reported in more than 30 species of birds. To date, the species infecting birds are C. baileyi, C. galli and C. meleagridis. In this study, the morphological, clinical and molecular characteristics of a Brazilian ostrich isolate of Cryptosporidium are described. The oocysts of this Brazilian isolate are larger and more elongated than those of Cryptosporidium previously reported in ostriches, which were morphologically similar to C. meleagridis. Morphological, biological and molecular analyses demonstrated similarity of this ostrich isolate with C. baileyi, suggesting that there are at least two Cryptosporidium species infecting ostriches; one with molecular, biological and morphological characteristics related to C.... |

| Land-cover change has been identified as one of the most important drivers of change in ecosystems and their services. However, information on the consequences of land cover change for ecosystem services and human well-being at local scales is largely absent. Where information does exist, the traditional methods used to collate and communicate this information represent a significant obstacle to sustainable ecosystem management. Embedding science in a social process and solving problems together with stakeholders are necessary elements in ensuring that new knowledge results in desired actions, behavior changes, and decisions. We have attempted to address this identified information gap, as well as the way information is gathered, by quantifying the... |

| An experiment was carried out to establish mean bone quality values of the tibiae and femora of ostriches and to evaluate these bones. The right leg bones of 10 males and 10 female African Black ostriches were evaluated. Birds were radiographed immediately after slaughter (during bleeding), with the aid of a portable X-ray apparatus. The obtained radiographs were scanned and bone mineral density means were obtained using software. Bone strength, Seedor index, and dry matter percentage were evaluated and correlated to weight gain during the finishing period (3-13 months of age). Mean values of the evaluated bone quality traits, not previously found in literature, were established. There were no significant differences between males and females in... |
