ABSTRACT Craniofacial variation and its relation to diet have been widely examined, but with less attention exclusively to the palate. Previous studies have shown that groups consuming a more resistant diet exhibit morphological differences in the craniofacial skeleton, including a longer and wider palate when compared to groups consuming a less resistant diet; similar patterns have been observed among captive vs. wild populations. Here, I present a 3D morphometric analysis of palatal ontogeny in tufted (Sapajus spp.) and untufted (Cebus spp.) capuchins and compare captive vs. free-ranging semi-provisioned Sapajus. Tufted capuchins are known to consume more mechanically resistant foods compared …

Velvet mites of the genus Podothrombium Berlese, 1910 are found worldwide with only two described species known from North America, both occurring on the west coast. The present study describes five new species occurring in the east, from both larval and post-larval stages. Species hypotheses are supported with morphology and analysis of mitochondrial (barcoding region of COI) and nuclear genes (D2-3 expansion regions of 28S rDNA). Specimens are incorporated from the Barcode of Life Data Systems (BOLD), allowing our dataset to span most of North America. Therefore, we were able to raise the number of Podothrombium in North America from …
