Abstract The Pleistocene glacial cycles had a strong influence on the demography and genetic structure of many species, particularly on northern-latitude taxa. Here we studied the phylogeography of the white-eared hummingbird (Hylocharis leucotis), a widely distributed species of the highlands of Mexico and Central America. Analysis of mitochondrial DNA (mtDNA) sequences was combined with ecological niche modelling (ENM) to infer the demographic and population differentiation scenarios under present and past conditions. Analyses of 108 samples from 11 geographic locations revealed population structure and genetic differentiation among populations separated by the Isthmus of Tehuantepec (IT) and the Motagua-Polochic-Jocotán (MPJ) fault barriers. ENM predicted a widespread distribution of suitable habitat for H. leucotis since the Last Inter Glacial (LIG), but this habitat noticeably contracted and fragmented at the IT. Models for historical dispersal corridors based on population genetics data and ENM revealed the existence of corridors among populations west of the IT; however, the connectivity of populations across the IT has changed little since the LIG. The shallow geographic structure on either side of the isthmus and a star-like haplotype network, combined with the long-term persistence of populations across time based on genetic data and potential dispersal routes, support a scenario of divergence with migration and subsequent isolation and differentiation in Chiapas and south of the MPJ fault. Our findings corroborate the profound effects of Pleistocene climatic fluctuations on the evolutionary history of montane taxa but challenge the generality of expanded suitable habitat (pine-oak forests) during glacial cycles.

The role of natural enemies in the control of the pear psylla, Psylla pyricola Foerst., has been of minor importance in the published history of this pest in North America. Jensen (1957) listed six species of parasites that attack the pear psylla nymph, but only one, Psylledontus insidiosus Cwfd. (Hymenoptera: Encyrtidae), is recorded from North America. Slingerland (1896) stated that the predators Chrysopa oculata Say (Neuroptera: Chrysopidae) and Adalia bipunctata (L.) (Coleoptera: Coccinellidae) were observed in the field feeding on psyllid eggs, nymphs and adults. Georgalla (1957) reported that Anthocoris nemorum L. (Hemiptera: Anthocoridae) fed upon pear psylla eggs and nymphs, but made no reference to effect upon psyllid populations.

Tibia Shaft

Direct evidence of paleoecological processes is often rare when the fossil record is poor, as in the case of the Cretaceous of eastern North America. Here, I describe a femur and partial tibia shaft assignable to theropods from two Late Cretaceous sites in New Jersey. The former, identifiable as the femur of a large ornithomimosaur, bears several scores interpreted as shark feeding traces. The tibia shaft has punctures and flaked bone from the bites of mid-sized crocodyliforms, the first documented occurrence of crocodyliform traces on dinosaur bone from the Maastrichtian of the Atlantic Coastal Plain. The surface of the partial tibia is also littered with indentations interpreted as the traces of invertebrates, revealing a microcosm of biological interaction on the coastal seafloor of the Cretaceous Atlantic Ocean. Massive crocodyliforms, such as Deinosuchus rugosus and the slightly smaller Deltasuchus motherali, maintained the role of terrestrial vertebrate taphonomic process drivers in eastern North America during the Cretaceous. The report of crocodyliform bite marks on the ornithomimosaur tibia shaft in this manuscript reinforces the importance of the role of crocodyliforms in the modification of terrestrial vertebrate remains during the Cretaceous in North America. The preserved invertebrate traces add to the sparse record of the presence of barnacles and other marine invertebrates on dinosaur bone, and the evidence of shark feeding on the ornithomimosaur femur support the “bloat-and-float” model of terrestrial vertebrate fossil deposition in marine deposits from the Cretaceous of eastern North America.
