Cranial Morphology, Taxonomy, and Systematics of Pachycephalosaurids (Dinosauria, Ornithischia)
DownloadSpring 2022
Pachycephalosauridae (pachcycephalosaurids) were small to medium sized bipedal ornithischians, known solely from the Late Cretaceous of North America and Asia. These dinosaurs are characterised by thick, often domed frontals and parietals (frontoparietal dome), which are thought to have been used...

Expression of PPARα modifies fatty acid effects on insulin secretion in uncoupling protein-2 knockout mice
Download2007
Fatehi-Hassanabad, Zahra, Chan, Catherine B.
Aims/hypothesis In uncoupling protein-2 (UCP2) knockout (KO) mice, protection of beta cells from fatty acid exposure is dependent upon transcriptional events mediated by peroxisome proliferator-activated receptor-α (PPARα). Methods PPARα expression was reduced in isolated islets from UCP2KO and...

Factors contributing to the competitiveness of Lactobacillus reuteri in sourdough and rodent gut
DownloadFall 2011
Lactobacillus reuteri is a common organism in cereal-based foods and a gut symbiont in humans and animals, yet the molecular mechanisms allowing its persistence in various niches are not well understood. L. reuteri LTH2584 produces reutericyclin and persists in industrial sourdoughs, where acidic...

Feather mites of the genus Proterothrix Gaud (Astigmata: Proctophyllodidae) from parrotbills (Passeriformes: Paradoxornithidae) in China.
Download2009
Three new species of the feather mite genus Proterothrix Gaud, 1968 (Proctophyllodidae: Pterodectinae) are reported from parrotbills (Passeriformes: Paradoxornithidae) in China. We describe Proterothrix paradoxornis n. sp. from Paradoxornis webbianus (type host) and Par. alphonsianus, P....

Populations of a host species may exhibit different assemblages of parasites and other symbionts. The loss of certain species of symbionts (lineage sorting, or ‘‘missing-the-boat’’) is a mechanism by which geographical variation in symbiont assemblages can arise. We studied feather mites and lice...

Pachyrhinosaurus is a peculiar ceratopsian known only from Upper Cretaceous strata of Alberta and the North Slope of Alaska. The genus consists of three described species Pachyrhinosaurus canadensis, Pachyrhinosaurus lakustai, and Pachyrhinosaurus perotorum that are distinguishable by cranial...

The evolutionary embryologist Gavin Rylands de Beer can be viewed as one of the forerunners of modern evolutionary developmental biology in that he posed crucial questions and proposed relevant answers about the causal relationship between ontogeny and phylogeny. In his developmental approach to...

Assis, Leandro C.S., Brigandt, Ingo
Taxa and homologues can in our view be construed both as kinds and as individuals. However, the conceptualization of taxa as natural kinds in the sense of homeostatic property cluster kinds has been criticized by some systematists, as it seems that even such kinds cannot evolve due to their being...

Peroxisomes are indispensable organelles that perform many essential metabolic activities. Thus, eukaryotic cells have evolved molecular mechanisms to ensure the inheritance of peroxisomes from mother cell to daughter cell at cell division. In the budding yeast Saccharomyces cerevisiae, the class...
