Microascus brevicaulis sp. nov., the Teleomorph of Scopulariopsis brevicaulis, Supports Placement of Scopulariopsis with the Microascaceae
Download1998
Abbott, Sean P., Sigler, Lynne, Currah, R.S.
Five isolates of Scopulariopsis brevicaulis have been found to form perithecia in addition to typical conidia. The teleomorph is described as Microascus brevicaulis sp. nov., characterized by small (70-130 pLm diam), black, ostiolate ascocarps that are papillate or very short-necked, and with a...

The first fossil echinoids are recorded from the Cayman Islands. A regular echinoid, Arbacia? sp., the spatangoids Brissus sp. cf. B. oblongus Wright and Schizaster sp. cf. S. americanus (Clark), and the clypeasteroid Clypeaster sp. are from the Middle Miocene Cayman Formation. Test fragments of...

With well over 3,400 described species, snakes undoubtedly represent one of the most successful groups of reptiles. Much has been written about their ecology, behavior, anatomy, relationships and evolution. However, despite the debate about the origin of this taxonomic group dating back to the...

A full understanding of the evolution of novel forms requires inference about their origins through the study of variation in extant taxa and clues from the fossil record. However, the origins of morphological diversity in many groups are obscured by the scarcity of transitional fossils or...

Osteology, Taxonomy, Phylogeny, and Body Shape Changes of Eocene Catostomid and Problematic Catostomid Fishes
DownloadFall 2016
Extant catostomid fishes occupy diverse aquatic ecosystems and niches in North America (NA). Less than 3% of catostomid taxonomic richness, or two species, are found outside of NA in Asia. Such adjunct and unbalanced distribution pattern has been established since the late Oligocene, when...

Palaeoenvironment and palaeoecology of three Cretaceous snakes: Pachyophis, Pachyrhachis, and Dinilysia
Download2001
Caldwell, M. W., Albino, A. M.
The palaeoecology of three Late Cretaceous snakes is evaluated. Pachyophis woodwardi Nopcsa, 1923 and Pachyrhachis problematicus Haas, 1979, are Cenomanian in age and are found in carbonate rocks deposited in marine inter-reef basin environments of the European and African Tethys Sea. Dinilysia...

The phylogenetic relationships of the destructive spruce budworm group of forest pests (Choristoneura fumiferana species complex) have previously been explored using allozymes, microsatellites, mitochondrial genes and a nuclear gene, but remain poorly resolved with conflicting topologies. I used...

Phylogeny of Nearctic Species of the Xylosteana Group of Archips Hübner (Lepidoptera: Tortricidae) Based on Combined Analysis of Morphological and Mitochondrial DNA Data Sets
Download2002
Sperling, F. A. H., Kruse, J. J.
Abstract: The Holarctic Archips xylosteana Group consists of at least 18 morphologically similar species in the Nearctic, three of which were synonymized with A. argyrospila by Razowski and subsequently returned to species status, two that were described since 1986 but are clearly related to A....
