Immune Investment Is Explained by Sexual Selection and Pace-of-Life, but Not Longevity in Parrots (Psittaciformes)
Investment in current reproduction should come at the expense of traits promoting future reproduction, such as immunity and longevity. To date, comparative studies of pace-of-life traits have provided some support for this, with slower paced species having greater immune function. Another means of investment in current reproduction is through secondary sexual characters (SSC). Investment in SSC...
متن کاملChromosome repatterning in three representative parrots (Psittaciformes) inferred from comparative chromosome painting.
Parrots (order: Psittaciformes) are the most common captive birds and have attracted human fascination since ancient times because of their remarkable intelligence and ability to imitate human speech. However, their genome organization, evolution and genomic relation with other birds are poorly understood. Chromosome painting with DNA probes derived from the flow-sorted macrochromosomes (1-10) ...
متن کاملA novel method for semen collection and artificial insemination in large parrots (Psittaciformes)
The paper described a novel technique for semen collection in large psittacines (patent pending), a procedure which was not routinely possible before. For the first time, a large set of semen samples is now available for analysis as well as for artificial insemination. Semen samples of more than 100 psittacine taxa were collected and analysed; data demonstrate large differences in the spermatol...
متن کاملA revised nomenclature and classification for family-group taxa of parrots (Psittaciformes)
The last 20 years have seen a resurgence in systematic studies of parrots (Aves: Psittaciformes). Principally but not solely molecular in nature, this body of work has addressed the circumscription of higher level groupings within the Psittaciformes and relationships among them. Stability has now emerged on many formerly contentious matters at these levels. Accordingly, we consider it appropria...
