Snout Shape in Extant Ruminants
Snout shape is a prominent aspect of herbivore feeding ecology, interacting with both forage selectivity and intake rate. Previous investigations have suggested ruminant feeding styles can be discriminated via snout shape, with grazing and browsing species characterised by 'blunt' and 'pointed' snouts respectively, often with specification of an 'intermediate' sub-grouping to represent ambiguou...
متن کاملSystematic revision and review of the extant and fossil snout butterflies (Lepidoptera: Nymphalidae: Libytheinae).
Extant and fossil genera and species in the Libytheinae (Nymphalidae) are revised and reviewed. The Libytheinae includes two genera: Libythea Fabricius and Libytheana Michener. Fifteen species and an additional 24 subspecies are recognized and 41 names are synonymized. Species recognized are: Libythea celtis (Laicharting), L. collenettei Riley, L. cinyras Trimen revised status, L. geoffroyi God...
متن کاملResolving the evolution of extant and extinct ruminants with high-throughput phylogenomics.
The Pecorans (higher ruminants) are believed to have rapidly speciated in the Mid-Eocene, resulting in five distinct extant families: Antilocapridae, Giraffidae, Moschidae, Cervidae, and Bovidae. Due to the rapid radiation, the Pecoran phylogeny has proven difficult to resolve, and 11 of the 15 possible rooted phylogenies describing ancestral relationships among the Antilocapridae, Giraffidae, ...
متن کاملPhylogeny of snout butterflies (Lepidoptera: Nymphalidae: Libyt- heinae): combining evidence from the morphology of extant, fossil, and recently extinct taxa
Snout butterflies (Nymphalidae: Libytheinae) are morphologically one of the most unusual groups of Lepidoptera. Relationships among libytheines remain uncertain, especially in the placement of the recently extinct Libythea cinyras and two fossils, L. florissanti, and L. vagabunda. The aim of this study is to present the first phylogenetic hypothesis of Libytheinae utilizing all available morpho...
متن کاملInferences of Diplodocoid (Sauropoda: Dinosauria) Feeding Behavior from Snout Shape and Microwear Analyses
BACKGROUND As gigantic herbivores, sauropod dinosaurs were among the most important members of Mesozoic communities. Understanding their ecology is fundamental to developing a complete picture of Jurassic and Cretaceous food webs. One group of sauropods in particular, Diplodocoidea, has long been a source of debate with regard to what and how they ate. Because of their long lineage duration (La...
