The orientation of the hindlimb is also unique to bats. The hip joint is rotated 90° so that the legs project sideways and the knee faces almost backwards. Due in part to the rotation of the hindlimb, the walking motion of bats differs from other tetrapods, often appearing awkward. The hindlimb is designed to support the patagium in flight and allow the bat to roost hanging from its hindlimbs. Most bats have a tendon system in the toes that locks the claws in place so the bat can hang upside down even when asleep.

The body of a bat is ventrally compressed with a short neck region. The bones tend to be slender and light-weight. The majority of the body weight is concentrated in the chest region due to the large flight muscles.

The overall shape of the head varies more in bats than within most other groups of mammals. Some bats have very elongated muzzles while others have broad, short faces. There is a correlation between the shape of the head and the type of food eaten. For example, most nectar feeders have long, narrow muzzles that are good for reaching into flowers, while many fruit eaters have short, broad faces good for biting rounded fruits (Hill and Smith, 1984).

The ears range from small and round to large and pointed, and often have a cartilaginous fold (tragus) present at the notch of the ear. There is additional variation in the nasal and lip regions of bats. Some bats have complex noseleafs, folds, or wrinkles on their muzzles.

A major misconception about bats is that they are blind. This idea originated from the fact that bats are able to successfully maneuver in the dark and often have small eyes. While some bats do have very small eyes (most Microchiroptera) many have large and complex eyes (Megachiroptera).

Bats usually have black or brown fur, although the fur can also be gray, white, red, or orange. In some species there are stripes on the face or down the back, or patches of white on the face or above the shoulder. The length of the fur also varies among species from short and dense to long and fluffy. The wing membrane is usually dark in color, although it may have white on the tips or be a lighter color around the bones in the membrane. A few bats have white or pale yellow wings. There are also little hairs on the membrane itself. These hairs can be the color of the wing or the same color as the body.

The bat monophyly hypothesis states the Megachiroptera and Microchiroptera are each others closest relatives in an evolutionary sense (i.e., they form a clade).

One conclusion to be drawn from the Yale-Columbia project is the need for better data, which requires funds.

Experiences like the recent biofuels surge, which is driving up food prices, show how treacherous even well-intentioned decisions about the environment can be when they're uninformed.

The same holds for consumers, who sometimes think paying somebody to plant a few trees will compensate for flying around the world in airplanes.

For such decisions, data are essential. If we're going to avoid squandering our natural resources, the quicker we begin to rely more on facts and less on assumptions, the better.

Some countries simply lie or make up the facts.

Today's Russian bureaucrats may still be fudging its environmental figures.

Among the worst offenders were Japan, South Korea, Brazil, the United States, Italy and Paraguay.

(While there are good comparative data on ozone, smog also includes nitrogen oxides, carbon monoxides and other components that are poorly tracked in most nations.) Among the best industrial countries were Malaysia, the United Kingdom and all of Eastern Europe (a legacy of the Soviet nuclear program).

Saudi Arabia, Egypt and the United Arab Emirates, which have more severe water problems.

Brazil is another country whose high rank—34th—is deceptive.

Brazil is a vast land blessed with an abundance of water, which yields energy relatively cheaply with no carbon emissions

Brazil is now the world's fourth biggest emitter of carbon, mainly due to the felling of trees.

By contrast, Belgium and the Netherlands, which share much in terms of population and geography with their neighbors, suffer from neglect of the environment—particularly in protecting native habitats.

Without an accurate assessment of the extent of the remaining oil, subsistence food-gatherers, consumers of commercial fish products from the area, and tourists have used mostly anecdotal evidence as the basis for economic decisions regarding resource utilization in the affected area.

Consequently, the Auke Bay Laboratory (ABL) with funding from the EVOS Trustee Council, took on the task of assessing the remaining oil along the shorelines of Prince William Sound during the summer of 2001

The primary objective of the project was to measure the amount of oil remaining in the intertidal zone of Prince William Sound.  Secondary objectives include determining the rate of decline of oil on these beaches, estimating the persistence of the remaining oil, and correlating the remaining oil with geomorphological features.

heavily and moderately oiled

The 2001 survey adopted a stratified random/adaptive sampling (SRAS) design. Two random pits were excavated to a depth of 0.5 m (1.6 feet) in every stratified block (0.5-m verticle drop in tide height) within a grid system established at each site. If subsurface oil was discovered in any of the randomly stratified origin pits, then additional adaptive pits were excavated above, below, to the right, and to the left of the origin pit until the extent of the oil patch was determined.

Buried or subsurface oil is of greater concern than surface oil.

Subsurface oil can remain dormant for many years before being dispersed and is more liquid, still toxic, and may become biologically available.

A disturbance event such as burrowing animals or a severe storm reworks the beach and can reintroduce unweathered oil into the water.

The toxic components of this type of surface oil are not as readily available to biota, although some softer forms do cause sheens in tide pools.

1) Surface oil was determined to be not a good indicator of subsurface oil. 2) Twenty subsurface pits were classified as heavily oiled.  Oil saturated all of the interstitial spaces and was extremely repugnant. These “worst case” pits exhibited an oil mixture that resembled oil encountered in 1989 a few weeks after the spill - highly odiferous, lightly weathered, and very fluid. 3) Subsurface oil was also found at a lower tide height than expected (between 0 and 6 feet), in contrast to the surface oil, which was found mostly at the highest levels of the beach (Table 3).  This is significant, because the pits with the most oil were found low in the intertidal zone, closest to the zone of biological production, and indicate that our estimates are conservative at best.

The possibility of continuing low level chronic effects of the Exxon Valdez oil spill seem very real now, although measurable population effects would be very difficult to detect in wild populations.

 Sea otters and harlequin ducks fall into this category

such as sea otters, harlequin ducks, and their intertidal prey.

The last beach assessment was completed in September 2001. Supporting chemical analyses will be completed in fall 2002, and a final report with statistical analyses and conclusions will be completed by April 2002.

"hot spots" of contaminated sediment.

Pathogens such as bacteria and viruses, which are often presentin urban runoff, can pose public health problems.

Drains Versus 400 or More Yards Away Found On Hard Copy-Storm Drain Runoff," Epidemiology, July 1999, Vol. 10, No. 4.Metals and polycyclic aromatic hydrocarbons (PAH) in urban runoffcan present a threat to aquatic life.

proved to betoxic to sea urchin fertilization in the Santa Monica Bay, anddissolved zinc and copper were determined to be contributors tothis toxicity. -Brown bullheads (a bottom-dwelling catfish) inthe Anacostia River developed tumors that were believed to becaused by PAHs associated in part with urban runoff. High PAHand heavy metal concentrations were found in crayfish tissuesamples from several urban streams in Milwaukee. The studyassociated these contaminants with storm water runoff.

The three primaryactivities used in these programs include efforts to characterizestorm water runoff; BMPs aimed at reducing pollutants in stormwater runoff to the maximum extent practicable; and reportingprogram activities, monitoring results, and costs of implementingthe program. Some BMPs are structural-meaning that they aredesigned to trap and detain runoff until constituents settle orare filtered out.

-good housekeeping" practices by the local government, such asoil collection and recycling, spill response, household andhazardous waste collection, pesticide controls, flood controlmanagement, and street sweeping; -public education programs, suchas storm-drain stenciling, to remind the public that trash, motoroil, and other pollutants thrown into storm drains end up innearby receiving waters;' -new ordinances to control pollutionsources, such as prohibiting the disposal of lawn clippings instorm drains and requiring pet owners to clean up after theirpets;" requirements that developers comply with storm waterregulations and incorporate erosion and sediment controls at allnew development sites; -requirements that runoff from propertiesowned or activities sponsored by the municipality be properlycontrolled; and -efforts to identify and eliminate illicitconnections and illegal discharges to the storm sewer systems,such as those from pipes carrying sewage.

Several officials in the cities we visited said that their annualcosts are likely to increase. A number of factors could affectthe costs. For example, a Baltimore City official explained thatthe anticipated, future program costs depend on several factors,including (1) requirements in watershed- management planscurrently being developed, (2) pollution-reduction goals the citywill be required to achieve, (3) requirements of the stateregulatory agency in future permits, and (4) requirements thecity may have to meet if TMDLs or numeric effluent limits areincorporated into NPDES storm water permits. Other city officialsalso expressed concern about the extent to which TMDLs couldaffect their future costs. These city officials are concernedthat when and if TMDLs are established, their future storm waterpermits may require that storm water runoff meet specific waterquality standards. For example, Los Angeles County's trash TMDLcould potentially drive the county's storm water management costsupward, and the county expects additional TMDLs to be imposed. Onthe other hand, Worcester officials estimated that their futurestorm water costs would be about the same as they were at thetime of our review-about $4.5 million per year.

but industrial and household waste removal is a growing concern. Per

capita tonnage has doubled in the past 20 years, and finding urban space to build more processing plants has been a challenge.

Due to the success of Camp Rock, a sequel, is also currently in development. The Jonas Brothers will also return as the band, connect three, and their youngest brother Frankie Jonas is also expected to star.

The series is slated to premiere in May, 2009.

gets so hot that it can boil water into steam

team can then be used to turn a turbine to make electricity.

California's Mojave desert, there are huge rows of solar mirrors arranged in what's called "solar thermal power plants"

this idea to make electricity for more than 350,000 homes

problem with solar energy is that it works only when the sun is shining

cloudy days and at night, the power plants can't create energy.

solar plants, are a "hybrid" technology

daytime they use the sun

night and on cloudy days they burn natural gas to boil the water so they can continue to make electricity.

form of solar power plants to make electricity is called a Central Tower Power Plant, like the one to the right - the Solar Two Project.

Sunlight is reflected off 1,800 mirrors circling the tall tower

mirrors are called heliostats

move and turn to face the sun all day long

light is reflected back to the top of the tower in the center of the circle where a fluid is turned very hot by the sun's rays.

luid can be used to boil water

make steam to turn a turbine and a generator.

We can also change the sunlight directly to electricity using solar cells.

Solar cells are also called photovoltaic cells

PV cells for short

be found on many small appliances

calculators

even on spacecraft

first developed in the 1950s for use on U.S. space satellites

made of silicon, a special type of melted sand.

sunlight strikes the solar cell, electrons (red circles) are knocked loose

move toward the treated front surface (dark blue color)

electron imbalance is created between the front and back

two surfaces are joined by a connector, like a wire, a current of electricity occurs between the negative and positive sides.

individual solar cells are arranged together in a PV module and the modules are grouped together in an array.

arrays are set on special tracking devices to follow sunlight all day long.

electrical energy from solar cells can then be used directly

used in a home for lights and appliances

in a business

Solar energy can be stored in batteries to light a roadside billboard at night

energy can be stored in a battery for an emergency roadside cellular telephone when no telephone wires are around.
