Background:
In the Ganges Delta, chronic arsenic poisoning is a health concern affecting millions of people who rely on groundwater as their potable water source. The prevalence of anemia is also high in this region, particularly among women. Moreover, arsenic is known to affect heme synthesis and erythrocytes and the...
Porapak Q, Chromosorb 102, and Tenax GC, three porous
polymers commonly used as adsorbents in headspace analyses were
investigated. The retention times of various low-boiling compounds
relative to water were measured on the collection columns to determine
which compounds would be lost during the water removal step
employed after sampling...
Flavor profiles of canned and frozen whole kernel sweet corn were
obtained by entraining the volatile compounds on Porapak 0 traps and
by subsequent analysis on temperature-programed, 500' by 0.03" ID
capillary columns (SF-96 or Carbowax 20M). Identification was based
on GC/MS data, retention indices (I[subscript E]'s) and retention times....
The rapid worldwide emergence of the amphibian pathogen Batrachochytrium dendrobatidis (Bd) is having a profound negative impact on biodiversity. However, global research efforts are fragmented and an overarching synthesis of global infection data is lacking. Here, we provide results from a community tool for the compilation of worldwide Bd presence...
Biochar has shown promise as a soil amendment for improvement of agricultural and forest productivity, remediation of heavy metals, and sequestration of carbon, but has not yet been adopted for widespread use in any of these applications. By assessing the production potential as a carbon sequestration tool, and the stability...
Piscivory by birds can be significant, particularly on fish in small streams and during seasonal low flow when available cover from predators can be limited. Yet, how varying amounts of cover may change the extent of predation mortality from avian predators on fish is not clear. We evaluated size-selective survival...
Patterns of salmon distribution throughout a riverscape may be expected to change over time in response to environmental conditions and population sizes. Changing patterns of use, including identification of consistently occupied locations, are informative for conservation and recovery planning. We explored interannual patterns of distribution by juvenile Coho Salmon Oncorhynchus...
Some good goals for a well-managed, small-acreage horse
farm are:
• A productive pasture with plenty of grass and few weeds
• Less dust during the dry season and less mud during the wet season
• Healthy horses free of problems associated with dust, manure,
mud, and toxic plants
•...
The goals for a well-managed small-acreage horse farm are:
A productive pasture with plenty of grass and few weeds
Almost no mud during the rainy season
All nutrients (manure and stall waste) generated by the horses
recycled to feed the pasture or removed from the farm and
recycled
Healthy horses...
In a population of the European common toad Bufo bufo from a rural pond in the region of Lake Glubokoe Regional Reserve in Moscow province, Russia, unexplained mass mortality events involving larvae and metamorphs have been observed over a monitoring period of >20 yr. We tested toads from this and...
