On four measures of taxonomic richness
Paleobiology, 2020Abstract The choice of measures used to estimate the richness of species, genera, or higher taxa is a crucial matter in paleobiology and ecology. This paper evaluates four methods called shareholder quorum subsampling, true richness estimated using a Poisson sampling model (TRiPS), squares, and the corrected first-

Reduced Taxonomic Richness of Lice (Insecta: Phthiraptera) in Diving Birds
Journal of Parasitology, 2006Avian lice occupy different habitats in the host plumage that the physical environment outside the host body may affect in several ways. Interactions between host plumage and water may be an important source of such effects. Here, we use a comparative approach to examine the effect of a host's diving behavior on the taxonomic richness of its lice ...

On the taxonomic position ofSciaromium lacustreHerz. & Rich. in Rich.
Journal of Bryology, 1986Abstract Sciaromium lacustre Herz. & Rich. in Rich. from Peru is misplaced in Sciaromium and a new genus, Richardsiopsis, is erected to accommodate it. Richardsiopsis is considered most closely related to Donrichardsia macroneuron (Grout) Crum & Anderson from Texas on the basis of their similar gametophyte characters including the strong costa, oblong ...

Challenges and Solutions for Measuring Taxonomic Richness of Aquatic Invertebrates in Wetlands
Freshwater BiologyABSTRACT Measurements of biodiversity are crucial to assessing the ecological integrity of ecosystems. However, adequately describing the range of organisms existing in habitats can be challenging, especially for the taxonomically rich invertebrates.

Changing Climate and Geographical Patterns of Taxonomic Richness
2014The geographic variation of taxonomic richness may be directly determined by climate through contemporaneous/ecological processes, versus other (e.g., historical/evolutionary processes) that happen to be collinear with contemporaneous climate. In Chapter 1 I evaluated hypotheses from both groups of explanations in North America.

Global moss diversity: spatial and taxonomic patterns of species richness
Journal of Bryology, 2013AbstractWe have analysed the global patterns of moss species diversity based on a dataset created from checklists, online databases, and herbarium records. We collected more than 100 000 distribution records for over 400 different geographical units and standardized species taxonomy using the TROPICOS database of the Missouri Botanical Garden.

PALAIOS, 2003
Using a field analysis of Upper Ordovician mollusc-rich faunas of the Cincinnati Arch, this study tests whether the large-scale patterns of Ordovician gastropods and bivalves observed in a companion study are maintained at the finer scales of individual strata and localities, and when utilizing abundance data in addition to taxonomic richness.

A CAZyme-Rich Genome of a Taxonomically Novel Rhodophyte-Associated Carrageenolytic Marine Bacterium
Marine Biotechnology, 2018Carbohydrate-active enzymes (CAZymes) have significant biotechnological potential as agents for degradation or modification of polysaccharides/glycans. As marine macroalgae are known to be rich in various types of polysaccharides, seaweed-associated bacteria are likely to be a good source of these CAZymes.
