“…Given the high level congruence detected, we built a supertree in amalgamating trees from different wasp lineages. As discussed previously (Hall and Harvey 2002;Racheli 2004), supertree construction based on topological character matrices such as MRP matrix is quite similar to BPA. However, it is not interpreted in terms of lineage losses and host switches.…”

When organisms are tightly bound in interspecific interactions over long evolutionary times, the diversification of the partners is rarely independent. The symbiotic partner (i.e., the "hostassociated" organism that lives part or its entire life cycle on another organism) is often constrained by the speciation of its hosts. There are numerous examples of phytophagous insects and parasites that specialize and phylogenetically track their host (Ehrlich and Raven 1964; Janz and Nylin 1998; Lopez-Vaamonde et al.

“…MRP has gained popularity due to its ease of applicability, but its scientific underpinnings remain still to be discovered (Racheli, 2004). Hackett et al (1995) suggested, however, that combining trees resulting from different phylogenetic methods into a consensus tree could be misleading, because it is not clear why to give as much weight to the results of "weak" methods than to more consistent, robust, and efficient ones.…”

“…Their analysis was based on the application of MRP (Matrix Representation with Parsimony) to construct a supertree using the available phenetic and phylogenetic hypotheses for parrots (see Munshi‐South and Wilkinson 2006 and references therein). However, the use of MRP lacks a rigorous theoretical and methodological basis, as emphasized by several authors (Gatesy et al 2002, Gatesy and Springer 2004, Racheli 2004). For these reasons, we analysed the available data on genome size according to the approach used by Gregory (2002b).…”

Several hypotheses have been proposed to explain genome size variation in birds. However, no general consensus has been reached thus far. In this study, we analysed the inter-and intraspecific variation of genome size in some parrot species, and we tested the hypotheses that (1) weaker fliers have larger genomes, and (2) long-living species have lower DNA content. In general, parrots have a mean genome size (2.93 pg/nucleus) comparable to that of other avian orders. Amazona ochrocephala tresmariae has the highest genome size (4.30 pg/nucleus) among parrots. As expected, weaker flyers have larger genomes than better ones. In contrast to our prediction, we found a positive correlation between genome size and longevity. Finally, the species-group Amazona has a higher DNA content than the two groups Ara and Cacatua. Since oxidative stress is causally related to longevity, we suggest that DNA oxidative damage could have acted to some extent as a constraint on GS variation in parrots and perhaps also in other avian orders.
