Plant ash derived from fire plays an important role in nutrient balance and cycling in ecosystems. Factors that determine the composition and availability of ash nutrients include fire intensity (burn temperature and duration), plant species, habitat nutrient enrichment, and leaf type (live or dead leaf). We used laboratory simulation methods to evaluate temperature effects on nutrient composit...

We surveyed 792 larval and 12,400 adult Coquillettidia perturbans for mermithid nematodes in 1990. Collections were made from cattail marshes in the greater Boston area. No mermithids were found in the adult mosquitoes, nor in larvae collected in mid-season, but 3 were found in larvae collected during September and October. This is only the second recorded occurrence of mermithids in Cq. pertur...

Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST), we detect a giant H i filamentary structure in sky region of 3077 < α 3110 and 409 δ 434. The has velocity range −170 to −130 km s−1, mean −150 putting it at Galactocentric distance 22 kpc. structure, which name Cattail, length 1.1 kpc, so far appears be furthest largest filament Galaxy. Its mass is calculated 6.5 × 104 M⊙ ...

The higher aquatic plant cattails has a wide distribution area, grows almost all over the world and number of unique properties. One these properties is sorption perianth fuzz cattail cobs. high capacity cobs difficult to explain from standpoint small specific surface area this material. data obtained by authors а presented on characteristics Typha latifolia as sorbent oil products. VOPR reache...

Typha latifolia (cattail) forms natural stands in the transition zone of artificial flotation and mine tailings ponds is contaminated with extremely high concentrations metals. We assessed absorption capacity plant, metal transfer to leaves, effects elevatedmetal on antioxidant enzyme activities. Soil acidity, pseudo-total available content substrate, plants were examined. The elevated activiti...

To understand long-term changes in Chicago region wetlands, in 2002 we investigated the status of 31 high quality grassor sedge-dominated wetland plant communities that were originally sampled in 1976. Our objectives were to quantify vegetation changes over time by resampling transects and then correlating changes with site fire histories, as well as other factors linked with compositional and ...
