Ecological gradients within a Pennsylvanian mire forest
William A. DiMichele, H. J. Falcon-Lang, W.J. Nelson, S.D. Elrick, P.R. Ames
2007, Geology (35) 415-418
Pennsylvanian coals represent remains of the earliest peat-forming rain forests, but there is no current consensus on forest ecology. Localized studies of fossil forests suggest intermixture of taxa (heterogeneity), while, in contrast, coal ball and palynological analyses imply the existence of pronounced ecological gradients. Here, we report the discovery of...

Ambiguous taxa: Effects on the characterization and interpretation of invertebrate assemblages
T. F. Cuffney, Michael D. Bilger, A.M. Haigler
2007, Journal of the North American Benthological Society (26) 286-307
Damaged and immature specimens often result in macroinvertebrate data that contain ambiguous parent-child pairs (i.e., abundances associated with multiple related levels of the taxonomic hierarchy such as Baetis pluto and the associated ambiguous parent Baetis sp.). The choice of method used to resolve ambiguous parent-child pairs may have a very...

2007, Applied and Environmental Microbiology (73) 2135-2143
Certain toxic elements support the metabolism of diverse prokaryotes by serving as respiratory electron acceptors for growth. Here, we demonstrate that two anaerobes previously shown to be capable of respiring oxyanions of selenium also achieve growth by reduction of either tellurate [Te(VI)] or tellurite [Te(IV)] to elemental...
