Autor: Diarmaid Ó Foighil, Jingchun Li, Taehwan Lee, Paul Johnson, Ryan Evans, John B Burch
Publikováno v: PLoS ONE, Vol 6, Iss 5, p e20496 (2011)
A third of all known freshwater mollusk extinctions worldwide have occurred within a single medium-sized American drainage. The Mobile River Basin (MRB) of Alabama, a global hotspot of temperate freshwater biodiversity, was intensively industrialized

Recognition of a highly restricted freshwater snail lineage (Physidae: Physella) in southeastern Oregon: convergent evolution, historical context, and conservation considerations
Autor: Alexandria C. Moore, John B. Burch, Thomas F. Duda
Publikováno v: Conservation Genetics. 16:113-123
Non-marine mollusks have the highest number of documented extinctions of any major taxonomic group. Given their conservation status and the numerous cases of taxonomic uncertainty concerning freshwater mollusks in particular, the recognition of poten

Population aging is unprecedented, without parallel in human history, and the 21st century will witness even more rapid aging than did the century just past. Improvements in public health and medicine are having a profound effect on population demogr

Molecular Phylogenetic Revision of the Freshwater Limpet GenusFerrissia(Planorbidae: Ancylinae) in North America Yields Two Species:Ferrissia(Ferrissia)RivularisandFerrissia(Kincaidilla)Fragilis
Autor: Diarmaid Ó Foighil, John B. Burch, Andrea C. Walther
Publikováno v: Malacologia. 53:25-45
Members of the gastropod genus Ferrissia Walker, 1903, have a near-cosmopolitan distribution in freshwater ecosystems. Five North American species, distinguished by conchological, habitat, and distributional details, are generally recognized. However

E Pluribus Unum: A phylogenetic and phylogeographic reassessment of Laevapex (Pulmonata: Ancylidae), a North American genus of freshwater limpets
Autor: John B. Burch, Andrea C. Walther, Diarmaid Ó Foighil, Taehwan Lee
Publikováno v: Molecular Phylogenetics and Evolution. 40:501-516
The North American freshwater limpet genus Laevapex (Walker, 1903) is a ubiquitous inhabitant of lentic and slow-moving lotic habitats east of the Rocky Mountains, but uncertainty clouds its systematic affinities, the phylogenetic validity of its con

Crossing the Continental Divide: the Columbia drainage species Juga hemphilli (Henderson, 1935) is a cryptic member of the eastern North American genus Elimia (Cerithioidea: Pleuroceridae)
Autor: Diarmaid Ó Foighil, Jae Jin Kim, Hyun Chol Hong, John B. Burch, Taehwan Lee
Publikováno v: Journal of Molluscan Studies. 72:314-317
Pleurocerid gastropods are ecologically prominent and diverse members of the North American freshwater malacofauna. However, their systematic study has been greatly complicated by pronounced conchological variability. Almost 1,000 taxa have been desc

MOLECULAR PHYLOGENY OF CERTAIN THAI GASTROCOPTINE MICRO LAND SNAILS (STYLOMMATOPHORA: PUPILLIDAE) INFERRED FROM MITOCHONDRIAL AND NUCLEAR RIBOSOMAL DNA SEQUENCES
Autor: Taehwan Lee, Somsak Panha, Piyoros Tongkerd, Diarmaid Ó Foighil, John B. Burch
Publikováno v: Journal of Molluscan Studies. 70:139-147
The taxonomy of southeast Asian gastrocoptine pupillid micro land snails is based almost entirely on shell morphological characters, with an emphasis on apertural barriers. We aimed to test the phylogenetic utility of these characters by constructing

Polyploid Chromosome Numbers in the Torquis Group of the Freshwater Snail Genus Gyraulus (Mollusca: Pulmonata: Planorbidae)
Autor: John B. Burch, Younghun Jung
Publikováno v: CYTOLOGIA. 58:145-149
The first case of polyploidy in pulmonate snalis was found in the planorbid species Gyraulus (Torquis) circumstriatus (n=36, 2n=72). We now report the chromosome numbers of the other two members of the subgenus in North America, G. (T.) parvus and G.
