“…However, recent studies of wrens (Barker, 2007) and trogons (DaCosta & Klicka, 2008) have indicated a Central American origin for these avian taxa with multiple dispersal events into South America. Studies of other avian lineages have shown that South to North American dispersal is more common (Burns & Racicot, 2009: tanagers; Weir et al. , 2009: antbirds, woodcreepers, tanagers, and blackbirds).…”

Aim The closure of the Central American land‐bridge connection between North and South America 3.5 million years ago was a major biogeographic event that allowed considerable interchange of the previously isolated faunas of these continents. However, the role that this connection may have had in diversification of North and South American faunas is less well understood. The goal of this study was to evaluate the potential role of the formation of this land connection in generating diversity, through repeated rare dispersal events followed by isolation. Location North and South America. Methods We evaluated the role of the Central American land‐bridge connection in avian diversification using a molecular phylogeny based on four gene regions for mid‐sized New World doves. Diversification events were dated using a Bayesian relaxed clock analysis and internal calibration points for endemic island taxa with known island ages. Results The reconstructed phylogenetic tree was well supported and recovered monophyly of the genera Leptotila and Zenaida, but the quail‐doves (Geotrygon) were paraphyletic, falling into three separate lineages. The phylogeny indicated at least nine dispersal‐driven divergence events between North and South America. There were also five dispersal events in the recent past that have not yet led to differentiation of taxa (polymorphic taxa). Main conclusions Most of these dispersal‐driven diversification events occurred at the time of or after the formation of the Central American land bridge, indicating that this land connection played a role in facilitating divergence via dispersal of doves between continents.

“…Most authors place the host species, Gubernatrix cristata, in the family Emberizidae; however, Burns & Racicot (2009), using mitochondrial DNA data to reconstruct the phylogeny of thraupids, reveal that it may belong to the family Thraupidae. Consequently, I. bocamontensis was also compared with Isospora spp.…”

A new coccidian species (Protozoa: Apicomplexa: Eimeriidae) is reported from the endangered yellow cardinal Gubernatrix cristata (Vieillot) in southern Brazil. Isospora bocamontensis n. sp. has oöcysts which are subspheroidal, measure 32.1 × 28.9 μm and have a smooth, bilayered wall c.1.5 μm thick. The micropyle and the oöcyst residuum are absent, but a polar granule is sometimes present. Its sporocysts are ellipsoidal and 17.3 × 12.2 μm in size and contain a half-moon-shaped Stieda body, a prominent, homogeneous substieda body; and a sporocyst residuum composed of a compact mass of granules. The sporozoites have one refractile body and a nucleus.
