| effects of segregation and impact of specific feeding behaviour and additional fruit on voluntary nutrient and energy intake in yellow-shouldered amazons (amazona barbadensis) when fed a multi-component seed diet ad libitum. | parrots are commonly fed multi-component seed diets; however, both segregation and feeding behaviour might alter ingredient and nutrient composition of the offered diet. first, the nutritional impact of segregation was assessed as it occurs when multi-component diets are temporarily stored in food containers that are replenished before completely emptied and birds being fed from the upper layer. the most detrimental effect hereof was a vast decrease in mineral supplements, leading to a decrease ... | 2010 | 20662963 |
| complete mitochondrial genome of endangered yellow-shouldered amazon (amazona barbadensis): two control region copies in parrot species of the amazona genus. | amazona barbadensis is an endangered species of parrot living in northern coastal venezuela and in several caribbean islands. in this study, we sequenced full mitochondrial genome of the considered species. the total length of the mitogenome was 18,983 bp and contained 13 protein-coding genes, 22 transfer rna genes, two ribosomal rna genes, duplicated control region, and degenerate copies of nd6 and trna (glu) genes. high degree of identity between two copies of control region suggests their coi ... | 2013 | 23406580 |
| phylogeny of amazona barbadensis and the yellow-headed amazon complex (aves: psittacidae): a new look at south american parrot evolution. | the yellow-shouldered amazon (amazona barbadensis) is the sole parrot of the genus amazona that inhabits only dry forests. its population has been dropping; therefore it has been the topic of many studies and conservation efforts. however, the phylogenetic relationship of this species to potential relatives classified within the yellow-headed amazon (yha) complex are still not clear. therefore, we used more extensive data sets, including the newly sequenced mitochondrial genome of a. barbadensis ... | 2014 | 24823658 |
| qualitative impact evaluation of a social marketing campaign for conservation. | social marketing campaigns use marketing techniques to influence human behavior for the greater social good. in the conservation sector, social marketing campaigns have been used to influence behavior for the benefit of biodiversity as well as society. however, there are few evaluations of their effectiveness. we devised an approach for evaluating the influences of social marketing campaigns on human behavior and conservation outcomes. we used general elimination methodology, a theory-driven qua ... | 2019 | 30178894 |
