Chronic exposure to coal fly ash causes minimal changes in corticosterone and testosterone concentrations in male southern toads Bufo terrestris  

SciTech Connect (OSTI)

More than 50% of the electricity in the United States is produced by coal-burning power plants. The byproduct of coal-burning plants is coal fly ash, which contains increased concentrations of trace metals and is disposed of in collection basins. Southern toads (Bufo terrestris) frequently use these basins for reproduction. Male toads were collected in spring 2001 and 2002 from an ash basin and a reference site and divided into four groups: toads collected at the control site and maintained on (1) control substrate and food or (2) ash and contaminated food and toads collected at the ash site and maintained in (3) control or (4) ash conditions. Blood was collected periodically during 5 months to determine testosterone and corticosterone concentrations. Reference to ash toads exhibited a significant, transient increase in corticosterone at 4 weeks, but neither corticosterone nor testosterone continued to increase beyond this time. In contrast, toads caught and maintained on ash did not exhibit increased corticosterone. Testosterone in these toads appeared to be unrelated to ash exposure. This unexpected lack of a corticosterone response and no effect on testosterone suggests that toads chronically exposed to trace metals can acclimate to a polluted environment, but they may still experience subtle long-term consequences.

Surface, airborne, and satellite-based observations were collected to study the biological and physical processes and conditions that govern the exchanges of radiative energy, water, heat, carbon, and trace gases between boreal forest ecosystems and the atmosphere, particularly those processes that may be sensitive to global change. The objectives of the BOREAS project were: To improve process models that describe the exchanges of radiative energy, water, heat, carbon, and trace constituents between the boreal

Toad Toad Nature Bulletin No. 158 June 5, 1948 Forest Preserve District of Cook County William N. Erickson, President Roberts Mann, Supt. of Conservation THE TOAD The toad, distinguished by its wide heavy body, dry warty skin and a large kidney-shaped gland on each shoulder, is a most interesting and valuable animal. There are many superstitions about this gentle harmless amphibian so loathed by many people. It is not evil or venomous; it does not "rain down" from the sky; it cannot exist for centuries sealed in the heart of a tree or solid rock; it does not cause warts. From those two big glands and from the "warts", which are also glands, a toad can secrete a milky fluid which is harmless to man but which makes it distasteful to most animals. However, they are eaten by most large snakes and by many hawks, owls, herons and bitterns. Because its food is chiefly insects and their larvae, of which it consumes great quantities, the toad is a valuable friend to the farmer and gardener even though it also eats spiders and earthworms.

Effect of parathyroid hormone on transport by toad and turtle bladder  

SciTech Connect (OSTI)

The authors recently demonstrated that parathyroid hormone (PTH) inhibited both vasopressin- and cyclic AMP-stimulated water transport in the toad bladder. This was associated with an increase in calcium uptake by isolated epithelial cells. They postulated that PTH exerts its action on H/sub 2/O transport by directly stimulating calcium uptake. The current study was designed to compare the effects of PTH and the calcium ionophore, A23187, on H/sub 2/O and Na transport and H..mu.. secretion in toad and turtle bladders. In toad bladder, PTH and A23187 decreased arginine vasopressin (AVP)-stimulated H/sub 2/O flow and short-circuit current (SCC) after 60 min serosal incubation. In turtle bladder A23187 decreased SCC to 79.3 +/- 3.6% of base line (P < 0.05), and significantly decreased RSCC as well. PTH had no effect on SCC or H/sup +/ secretion in turtle bladders. Both PTH and A23187 increased /sup 45/Ca uptake in toad bladder epithelial cells; only A23187 increased /sup 45/Ca uptake in the turtle bladder. The different action of PTH in these two membranes, compared with that of the calcium ionophore, illustrates the selectivity of PTH on membrane transport. PTH increases calcium uptake and decreases transport only in a hormone-sensitive epithelium, whereas the ionophore works in virtually all living membranes. The mode of action of these two agents to increase calcium uptake is, therefore likely different.

Frequently Asked Questions About Frogs

FROG FAQs. . . FROG FAQs. . . So what makes a frog a frog? Frogs and toads are amphibians, which means they live their lives both in water and on land. Typically, frogs breed and spend thier juvenile (or "larval") stage in the water, then spend some or virtually all of their adult lives on the land. Frogs and toads are distinguished from salamanders (which are also amphibians) by the fact that adults do not have a tail. Do all frogs live in the water? No. The amount of time that adults spend in the water varies enormously. Bullfrogs and green frogs, although they have lungs and breathe air, spend almost all their adult lives in the water. On the other end of the spectrum, toads and treefrogs spend the majority of their adulthood outside of water. All frogs and toads, however, must eventually come back to the

Frogs are cold-blooded, or "poikilothermic," which means that their body temperature is affected by their surroundings. Frogs have very interesting life cycles. Like all amphibians, adults breed and lay eggs in small bodies of water, like ponds or streams. Although many frogs remain tied to the water, toads, tree frogs and some others spend nearly their entire adult lives on land. All frogs and toads must return to water, though, to breed. Playing Their Part Frogs and toads are vital components of the ecosystem. Adult frogs eat insects and other small animals and are in turn preyed upon by larger predators. Tadpoles are primarily vegetarian, but they also serve as scavengers. Tadpoles can be a significant food item for fish, mammals, and

Effect of Cumulus Cloud Formation on Boundary Effect of Cumulus Cloud Formation on Boundary Layer Turbulence A. S. Frisch, B. E. Martner, and B. W. Orr National Oceanic and Atmospheric Administration Environmental Technology Laboratory Boulder, Colorado D. H. Lenschow National Center for Atmospheric Research Boulder, Colorado Introduction The National Oceanic and Atmospheric Administration's (NOAA's) 35-GHz Doppler radar measured the turbulent motions in the planetary boundary layer (PBL) over the boreal forest as a contribution to the Boreal Ecosystem-Atmosphere Study (BOREAS) during the summer of 1994. The radar is sensitive enough to detect not only weakly and non-precipitating clouds (Martner and Kropfli 1993) but also small natural particulates that are commonly suspended in the clear PBL during warm seasons over land.

FREQUENCY DISTRIBUTIONS OF 90SR AND 137CS CONCENTRATIONS IN AN ECOSYSTEM OF THE 'RED FOREST' AREA IN THE CHERNOBYL EXCLUSION ZONE  

SciTech Connect (OSTI)

In the most highly contaminated region of the Chernobyl Exclusion Zone: the 'Red Forest' site, the accumulation of the major dose-affecting radionuclides ({sup 90}Sr and {sup 137}Cs) within the components of an ecological system encompassing 3,000 m{sup 2} were characterized. The sampled components included soils (top 0-10 cm depth), Molina caerulea (blue moor grass), Camponotus vagus (carpenter ants) and Pelobates fuscus (spade-footed toad). In a comparison among the components of this ecosystem, the {sup 90}Sr and {sup 137}Cs concentrations measured in 40 separate grids exhibited significant differences, while the frequency distribution of the values were close to a logarithmically normal leptokurtic distribution with a significant right-side skew. While it is important to identify localized areas of high contamination or 'hot spots,' including these values in the arithmetic mean may overestimate the exposure risk. In component sample sets that exhibited logarithmically normal distribution, the geometrical mean more accurately characterizes a site. Ideally, risk assessment is most confidently achieved when the arithmetic and geometrical means are most similar, meaning the distribution approaches normal. Through bioaccumulation, the highest concentrations of {sup 90}Sr and {sup 137}Cs were measured in the blue moor grass and spade-footed toad. These components also possessed distribution parameters that shifted toward a normal distribution.

New England Wind Forum: Am I in Danger?  

Wind Powering America (EERE)

Am I in Danger? Am I in Danger? With tens of thousands in operation across the world, wind turbines have demonstrated an excellent safety track record. Primary safety issues of concern are the icing of the blades and resulting shedding of the ice and the potential impact of a blade throw. Ice Shedding Under certain conditions in climates such as those found in New England, ice can accumulate on wind turbine blades. The release of that ice from moving turbine blades is possible. (The potential is clearly highest at mountain-top sites, remote from most observers in the harshest of weather.) A wind installation typically addresses such possibilities by employing adequate setbacks between each turbine and any nearby residences to avoid risk. Severe ice buildup will lead to automatic turbine shut down until the condition improves. Modern turbines can be equipped with cold weather packages, which make them adaptable to temperatures as low as -40 Celsius, reducing the risk of ice accumulation. These packages include special coatings on the blades to eliminate the adherence of ice, thermostat-controlled resistive element forced air heaters strategically placed to heat instruments and operating components during cold weather conditions to prevent the formation and adherence of ice, and low-temperature lubricants. No studies have been conducted in the United States concerning ice shedding from wind turbine blades. The 1998 European study, "Assessment of Safety Risks Arising from Wind Turbine Icing" (PDF 57 KB) Download Adobe Reader by European Commission, DGXII, and the UK Department of Trade and Industry examines the issue as well as the study "Risk Analysis of Ice Throw From Wind Turbines" (PDF 297 KB) Download Adobe Reader presented in April 2003 at BOREAS conference in Finland.

School Trips & Projects in Spring  

Broader source: All U.S. Department of Energy (DOE) Office Webpages (Extended Search)

& Projects in Spring & Projects in Spring Nature Bulletin No. 484 March 9, 1957 Forest Preserve District of Cook County Daniel Ryan, President Roberts Mann, Conservation Editor David H. Thompson, Senior Naturalist SCHOOL TRIPS & PROJECTS IN SPRINg Spring is the morning of the year when nature reawakens. The days become noticeably longer and warmer. We feel an urge to get out-of- doors and see green growing plants, early wildflowers, and swelling buds on trees and shrubs; see and hear birds returning from their winter homes; hear the mating songs of frogs and toads. The nearest forest preserve, park, meadow or hedgerow -- even a city street or weedy vacant lot -- will have a wealth of plant and animal life. March is a chancy month for field trips but spring can be perking in a classroom before many signs of it appear outdoors. One twig of a forsythia bush, placed in a bottle of water, will soon display its yellow flowers; willow and aspen twigs will develop fat fuzzy catkins; the end of branches from cottonwood, soft maple and elm trees will reveal how some of their winter buds produce flowers and others burst into leaves. The long reddish catkins on a male cottonwood are showy but the small flowers of a maple or an elm are no less beautiful, although seldom noticed on the trees.

Some Lizards of the Middle West

Lizards of the Middle West Lizards of the Middle West Nature Bulletin No. 344-A May 10, 1969 Forest Preserve District of Cook County George W. Dunne, President Roland F. Eisenbeis, Supt. of Conservation SOME LIZARDS OF THE MIDDLE WEST More than 2,500 kinds of lizards are now known in the world, and they vary more widely in size, shape, color and habit than any of the other three groups of reptiles -- the snakes, the turtles and the alligators. Three kinds of lizards are known to live within 50 miles of Chicago but they are so scarce, and so wary or secretive, that the total number found by all the reptile enthusiasts is often only one or two a year. Farther south they become more common and farm boys know them well. Lizards, having dry scaly skins that they shed from time to time, should not be confused with the salamanders which, altho also four- legged and cold-blooded, are amphibians -- not reptiles -- and have moist smooth skins. The only live lizards that most of us ever see are in the zoos, notably the sluggish Gila Monster which is one of the only two poisonous species; or a friendly little Horned "Toad" which someone may have brought back from the Southwest; or one of those little American chameleons sometimes sold at carnivals or county fairs in states where that is still permitted.
