A new species of desert shrew, Notiosorex, based on nuclear and mitochondrial sequence data /
Mitochondrial DNA variation in water shrews (Sorex palustris, Sorex bendirii) from western North America: implications for taxonomy and phylogeography
Inter- and intra-specific variations in cytochrome b (Cytb) sequence were assessed in 22 specimens of Sorex palustris Richardson, 1828 and 6 specimens of Sorex bendirii (Merriam, 1884) from 20… Expand
Chiton aorangi n. sp., a brooding chiton (Mollusca: Polyplacophora) from northern New Zealand
TLDR
Based on an examination of the relevant types, Chiton aorangi is differentiated from its nearest relative,Chiton themeropis Iredale, 1914, and from two other New Zealand species, chiton torri Suter, 1907 and Chiton pelliserpentis Quoy & Gaimard, 1835. Expand
IDENTIFYING VOUCHER SPECIMENS INVOLVING RISK: SHREWS FROM CHORNOBYL, UKRAINE
TLDR
DNA sequences from the cytochrome-b gene were analyzed to minimize radiation exposure and to evaluate an inexpensive molecular tool in identifying species of shrew, and substantially reduced exposure to radioactivity present in the archived material. Expand
Lepidozona beui n. sp. (Mollusca: Polyplacophora) from New Zealand
TLDR
In the absence of geographically close members of the genus Lepidozona, L. beui is specifically differentiated from the northern pacific species L. mertensii (von Middendorff, 1847), type species for the genus. Expand
Morphological changes in Onithochiton neglectus Rochebrune, 1881 (Mollusca: Chitonidae), and their taxonomic significance
TLDR
Children of Onithochiton neglectus have tricuspid second lateral teeth, an anterior mucro, an abbreviated gill-line, scale-like elements on the dorsal surface of the girdle, and a tegmentum which either lacks or possesses only a few, relatively large, ocelli. Expand
MOLECULAR EVIDENCE FOR GENETIC SUBDIVISIONS IN THE DESERT SHREW, NOTIOSOREX CRAWFORDI
Abstract Examination of cytochrome-b DNA sequences from specimens of Notiosorex crawfordi, the desert shrew, indicate that within this taxon there are at least 3 major subdivisions reflecting levels… Expand
The genus Rhyssoplax Thiele in the New Zealand Region (Mollusca: Polyplacophora)
TLDR
The New Zealand Recent species of Rhyssoplax Thiele 1893 recognised here are R. canaliculata, R. aerea, and R. stangeri, which are reillustrated and compared with the New Zealand species. Expand
