Mitochondrial DNA from the extinct dusky seaside sparrow (Ammodramus maritimus nigrescens) was compared in terms of nucleotide sequence divergence to mitochondrial DNAs from extant populations of seaside sparrows. Analyses of restriction sites revealed a close phylogenetic affinity of A. m. nigrescens to other sparrow populations along the Atlantic coast of the United States but considerable ge...

Nature-based, low technology wastewater treatment systems can benefit small and remote communities. Adding a constructed floating wetland (CFW) to waste stabilization ponds enhance efficacy at cost, depending on appropriate macrophytes. In cold climates, harsh growing conditions may limit CFW success, requiring research under-ambient field conditions. Seven native macrophytes were assessed for ...

Recently, Mouriño et al. (2008) reported the first record in Brazil of the filamentous bacteria Flexibacter maritimus (Wakabayashi et al., 1986) from the hatching of Litopenaeus vannamei post-larvae (Boone, 1931). In our view, a generalized lack of clarity about this identification has occurred and the discussion of some issues raised in the work is beyond the scope of this commentary. As Mouri...

A previous study showed that ammonia oxidation by the Thaumarchaeota Nitrosopumilus maritimus (group 1.1a) was resistant to concentrations of the C8 1-alkyne, octyne, which completely inhibits activity by ammonia-oxidizing bacteria. In this study, the inhibitory effects of octyne and other C2 to C10 1-alkynes were evaluated on the nitrite production activity of two pure culture isolates from Th...

In order to study the economical, efficient, and environmentally friendly techniques for treatment of acid mine drainage (AMD), this paper investigated effects watering with AMD on growth condition, resilience four wetland plants, as well uptake transport pollutants by plants. The results showed that Typha orientalis was more resistant (irrigation increased its catalase activity glutathione con...
