[font=Tahoma][size=12pt]4 Bird[/size][/font]
qs%OP2l
Z D6SB [font=Tahoma][size=12pt]We have just seen two [b]contemporary[/b] large birds that cannot fly: the [color=red]emu [/color]and the [color=red]ostrich[/color]. Over here is an interesting [color=red]specimen[/color] from the past. This [color=red]stuffed[/color] animal isn’t a giant[color=red] penguin it[/color] appears to be, but[color=red] an auk[/color]. This particular kind of auk is very [color=red]rare[/color]; only [color=red]seventy eight skins[/color] are known to exist[color=red] and [/color]most are not preserved as well as this one. The great auk, as you can see, [color=red]was[/color] a rather large bird [color=red]and[/color] it couldn’t fly, either. However, eviden[color=red]ce [/color]suggest[color=red]s[/color] that the auk [color=red]was an excellent swimmer [/color]and diver. Unfortunately, those abilities didn’t protect[color=red] it[/color] from being [color=red]easy prey [/color]for hungry [color=red]sailors[/color], who[color=red] years ago sailed[/color] the[color=red] very [/color]cold and [color=red]often [/color]icy water[color=red]s[/color] of[color=red] Greenland, Iceland[/color] and Scotland. In fact, evidence suggests that the auk was rather tasty and that its eggs, excuse me, that its eggs and [color=red]feathers[/color] [color=red]were[/color] useful [color=red]as well[/color]. Still, [color=red]it isn’t[/color] clear [color=red]what [/color]other factors[color=red] led[/color] to the large bird’s [color=red]demise[/color] around 1844, the last time anyone reported seeing one. Of course, we believe [color=red]it’s[/color] important to take[color=red] extra precautions [/color]to preserve the remaining great auk skins. After all, these specimen[color=red]s[/color] should prove [color=red]invaluable[/color] for future scientific research. Does anyone have any questions before we move [color=red]on [/color]to our next bird exhibit? [/size][/font]

[font=Tahoma][size=12pt]5 Tyrannosaurus rex[/size][/font]R Y jo:?:kD
[font=Tahoma][size=12pt]Before I tell you [color=red]about the[/color] interesting discovery related to [color=red]Tyrannosaurus rex[/color], I need to review something we studied last semester, the differen[color=red]ce[/color] between what are[b] commonly [/b]called the cold-blooded and warm-blooded animals. In warm-blooded animals, birds and mammals for example, the body temperature [color=red]normally [/color]stay[color=red]s[/color] within a narrow range, no matter what the outside temperature is. As a result, a warm-blooded animal is usually active in both cold and [color=red]hot[/color] [color=red]weather[/color], because its body temperature can adjust to the temperature of [color=red]its[/color] environment. On the other hand, cold-blooded animals, such as most reptiles, amphibians and insects, are unable to create [color=red]enough[/color] heat [color=red]internally [/color]to [b]raise [/b][color=red]their[/color] temperature above the temperature of the environment. So, for example, the temperature of a cold-blooded animal falls when the environment is cool. I hope this distinction is clear. Now moving on to Tyrannosaurus rex. You may know that dinosaurs, being reptiles, are generally believed to [color=red]have been[/color] cold-blooded. Well, a recent research [color=red]study found[/color] that the chemical composition [color=red]of the bones [/color]of Tyrannosaurus rex [color=red]was consistent [/color]with the bone[color=red]s[/color] of an animal that has a [color=red]very [/color]narrow range of [color=red]internal [/color]temperature, indicating that it [color=red]was[/color] probably warm-blooded.

v$}.f#l.P4gph `-p [font=Tahoma][size=12pt]6 electrical fish[/size][/font]
!I*_`n'w [font=Tahoma][size=12pt]Listen to a guide in[color=red] aquarium[/color].[/size][/font]G8i8z;Q ^W
[font=Tahoma][size=12pt]This room is devoted to electrical fish. [color=red]The eel in the tank [/color]behind me can produce a strong [color=red]jolt of [/color]electricity to [color=red]stun[/color] its prey, but most of the fish [color=red]in[/color] here produce only weak[color=red] electrical [b]impulses[/b][/color] that are useful for [color=red]navigating[/color], locating food[color=red] and even for [/color]communicating. The knife fish is a good example. This fish navigates using tiny receptors in the skin that are sensitive to electrical impulses. The knife fish produces [color=red]an[/color] electrical signal and receptors in its skin let it know [color=red]when[/color] the signal is distorted by[color=red] a tree root or some [/color]other [b]obstacle[/b], so it can go around it. Fish also [color=red]use the[/color] ability to produce and detect electrical impulses to communicate. They can tell each other what species they belong to, how big they are, and whether they are male or female. We[color=red] have a tank here that is especially equipped to convert the inaudible signals fish produce[/color] into sound[color=red]s [/color]you can hear when you put on [color=red]these [/color]headphones. I urge you all to [color=red]listen in [/color]when I am done speaking. Now have a look at electrical[color=red] rays[/color]. Rays are especially [color=red]interesting[/color] to medical researchers because of the organ[color=red]s[/color] they use to produce electricity. [color=red]These[/color] organs contain a chemical that[color=red] carries[/color] signals from a nerve [color=red]ending[/color] to [color=red]the[/color] next, not only in rays, but also in people. By studying these organs, scientists hope to learn more about diseases that interrupt transmission [color=red]of impulses[/color] from one nerve to another. [/size][/font]

[font=Tahoma][size=12pt]7 Mouse[/size][/font].N7gWTc ]
[font=Tahoma][size=12pt]Human populations [color=red]near the equator[/color] have evolved dark skin [color=red]over many generations [/color]because of exposure to the fierce [color=red]rays [/color]of the Sun. A similar [b]phenomenon[/b] has also occurred in other parts of [color=red]the [/color]animal kingdom. The African grass mouse is a good example. Most [color=red]mice[/color] are [color=red]nocturnal[/color], but African grass mouse is active during[b] daylight [/b]hours. This means [color=red]that[/color] it spends its days searching for food in the [color=red]semidry bush[/color] and [color=red]scrub habitats[/color] [color=red]of the eastern[/color] and southern Africa. [color=red]Its fur is striped[/color], like a [color=red]chipmunk’s,[/color] which helps it blend in [color=red]with its [/color]environment. Because it spends a lot of time in the intense [color=red]tropical[/color] sun, the grass mouse has also evolved two separate safeguard[color=red]s[/color] against the [color=red]sun’s[/color] ultraviolet radiation. First, like the population[color=red]s[/color] of human[color=red]s[/color] in this region of the world, the skin of the grass mouse contains [color=red]lots of melanin[/color] or dark pigment. Second and quite unusual, [color=red]this [/color]mouse has a layer of melanin [color=red]pigmented [/color]tissue between [color=red]its [/color]skull and skin. This unique cap provides [color=red]an extra measure[/color] of protection for the [color=red]grass [/color]mouse and three other [color=red]types of African mouselike rodents[/color] that are active during the day. The only other species scientists have identified with the same sort of [color=red]skull adaptation[/color] is the white[color=red] tent-making[/color] bat [color=red]of [/color]the Central American[color=red] tropics[/color]. Although these bats sleep during the day, they do so [color=red]curled up[/color] with their heads [color=red]exposed[/color] to the sun. [/size][/font]

[font=Tahoma][size=12pt]8 Trees[/size][/font]I5_CjyYy
[font=Tahoma][size=12pt]Ok, in the last class, we talked about the [color=red]classification[/color] of trees and we ended up with a basic description of [color=red]angiosperms[/color]. You remember that those are plants with true flowers and seeds [color=red]that[/color] develop inside [color=red]fruits[/color]. The common [color=red]broadleaf[/color] trees we [color=red]have[/color] on campus fall [color=red]into[/color] this [b]category[/b], [color=red]but our pines don’t[/color]. Now, I hope you all followed my advice and [color=red]wore[/color] comfortable shoes, because as I said, today we are going to do a little field study. To get started, let me describe a couple of [color=red]the[/color] broadleaf trees we have in front of us. I am sure you’ve all noticed this big tree next to [color=red]Brant[/color] Hall. It’s a black [color=red]walnut[/color] that must be [color=red]80[/color] feet tall. As a matter of fact,[color=red] there is a plaque[/color] identifying it [color=red]as[/color] the tallest black walnut in the state. And from here, we can the beautiful [color=red]archway[/color] of tree at the [color=red]Commons[/color]. They are American [color=red]elms[/color]. The ones along the Commons were planted when the college was founded one hundred and twenty years ago. They have the distinctive dark green leaves that [color=red]look[/color] [color=red]lopsided[/color], because the two sides of the [color=red]leaf[/color] are unequal. I want you to notice the elm right outside [color=red]Jackson Hall[/color]. Some of its leaves [color=red]have[/color] withered and turned yellow, maybe due to Dutch elm disease. Only a few branches seem [b]affected[/b] so far, but if the tree is sick, it will have to be cut down. Well, let’s move on [color=red]and[/color] I will describe what we see as we go.

[font=Tahoma][size=12pt]9 Wasps[/size][/font]
u$M%N8R*\"jC._ [font=Tahoma][size=12pt]Today I want to talk to you about wasps and their nests. You will recall [color=red]that[/color] biologist[color=red]s[/color] divide species of wasps into two groups: [b]solitary[/b] and social. Solitary wasps, as the name [color=red]implies[/color], do not live together with other wasps. In most species, the male and female get together only to [color=red]mate,[/color] and then the female does all the work [color=red]of[/color] building [color=red]the[/color] nest and providing food for the [color=red]offspring [/color]by herself. Solitary wasps usually [color=red]make[/color] nests [color=red]in[/color] the ground and they separate the chamber[color=red]s[/color] for individual [color=red]offspring[/color] [color=red]with bits of[/color] grass, stone or mud, whatever is handy. What about social wasps? They form a community and work together to build and maintain [color=red]the[/color] nest. A nest begin[color=red]s[/color] in [color=red]the[/color] spring when [color=red]a fertile female[/color] wasp, called the queen, build[color=red]s[/color] [color=red]the[/color] first few compartment[color=red]s [/color]of the nests and lay[color=red]s[/color] eggs. The first offspring are small females that can not lay eggs. These females, called workers, then build a lot [color=red]of[/color] new compartments and the queen lays more eggs. They also care for the [color=red]new[/color] offspring and defend the nest with their [color=red]stingers[/color]. By the way, only female [color=red]wasps[/color] have the strings. Most social wasps make nests of paper. The female[color=red]s[/color] produce the paper by chewing up plant fiber[color=red]s[/color] or old wood. They spread the paper [color=red]in thin layers[/color] to [color=red]make[/color] cells in which the queen lays [color=red]her[/color] eggs. Most of you, I am sure, have seen these nests suspended [color=red]from[/color] tree[color=red]s[/color]. They may also be built [color=red]underground[/color] in[b] abandoned[/b][color=red] rodent burrows[/color]. [/size][/font]0s`n voE

[font=Tahoma][size=12pt]10 Spider[/size][/font]
^ Tc0HT$P3a1QE [font=Tahoma][size=12pt]Before moving on to a new topic, I want to finish our unit on [color=red]arachnids[/color] by looking [color=red]at[/color] what may [color=red]seem a very unusual[/color] aspect of spider behavior, a species [color=red]where[/color] the young spiders actually consume the body of their mother. Unlike most other [color=red]spiders[/color], this [color=red]species[/color] lay[color=red]s[/color] one, and only one, [color=red]clutch of [/color]forty eggs in her lifetime. The young spider[color=red]s[/color] hatch in middle spring or early summer inside [color=red]a[/color] [color=red]nest[/color] of [color=red]eucalyptus leaves[/color]. Their mother spends warm summer moths bringing [color=red]home[/color] large insects often ten times [color=red]her [/color]weight for meals. The catch [color=red]is[/color] always [b]significantly[/b] more than what [color=red]her[/color] young spiders can eat. So the mother [color=red]fattens herself up on this extra prey[/color] and store[color=red]s[/color] [color=red]the[/color] nutrients in her [color=red]extra[/color] unfertilized eggs. As the weather turns [color=red]colder[/color], there are [color=red]fewer[/color] insect prey to [b]hunt[/b]. That is when the nutrients stored in [color=red]those[/color] extra eggs begin to[color=red] seep[/color] into mother’s[b] bloodstream[/b]. So when there [color=red]are[/color] no more insects to feed to the young spiders, they attach themselves to [color=red]the[/color] mother’s[color=red] leg joints [/color]and draw [b]nourishment[/b] by sucking the[color=red] nutriment-rich[/color] blood. After several weeks, the mother is [color=red]depleted[/color] of all nutrients and she dies. But then, how do the young get nourishment? They start to feed on one another. Now, if you recall our discussion of [color=red]Darwin[/color], you will see the evolutionary value of this; only the strongest spider of the clutch will survive in the [color=red]cannibalism[/color]. And the mother spider will have [color=red]ensured[/color] [color=red]that[/color] her genes have [color=red]an[/color] increased[color=red] chance of survival [/color]through future generations.

[font=Tahoma][size=12pt]11 Kangaroo[/size][/font];CrTB7vW/] Wl
[font=Tahoma][size=12pt]Now we are entering [color=red]K[/color]angaroo [color=red]C[/color]ountry. In all, there are more than fifty different species of kangaroo [color=red]and[/color] the advantage of zoos like ours is that you see them in [color=red]their[/color] natural [b]habitat[/b]. The ones we have all live in grasslands. On my right, you can see one of the [color=red]biggest[/color] [color=red]types[/color]: the [color=red]red[/color] kangaroo. It travels about twenty miles per hour. It looks like hard work, [color=red]but hopping actually [/color]let[color=red]s[/color] kangaroo conserve more energy than another animal could when running on four legs. In fact, up to a certain point, the faster a kangaroo goes the more energy it conserves. Rather than taking more hops to increase speed, the kangaroo makes [color=red]the length of[/color] each jump longer. Let’s stop here for a minute. Take a look[color=red] over on your right at this[/color] group of kangaroo[color=red]s[/color] resting. Can you see [color=red]that[/color] their ears [color=red]are[/color] moving? Hearing may well be the kangaroo’s most important sense. Their two large ears can move [b]independently[/b], so sometimes one ear is pointing forward and the other toward [color=red]the[/color] rear. Kangaroo’s eyesight is also excellent. They have a [color=red]wide[/color] field of vision [color=red]and[/color] like most [color=red]grazing[/color] animals, they are good at detecting movement. Before we move on, I’d like to point out one more thing: if you look [color=red]closely[/color], you can see a [color=red]joey[/color], [color=red]that’s[/color] [color=red]a[/color] baby kangaroo, peering out of [color=red]its[/color] mother’s [color=red]pouch[/color]. Before long [color=red]that[/color] joey will [color=red]be out of [/color]the pouch for good. [color=red]The[/color] mother will push it out by the time it’s eight moths old. [/size][/font]

[font=Tahoma][size=12pt]12 Frog[/size][/font]
['^%o;M&@Z&E;n [font=Tahoma][size=12pt]If you[color=red] liked[/color] the colorful animal[color=red]s[/color] we just saw, you’re going to [color=red]love[/color] [color=red]these[/color] next animals. Frogs.
&MxJ4ZxXz You [color=red]might[/color] not normally think [color=red]of[/color] frogs as[color=red] being [/color]colorful, but these [color=red]frogs[/color] definitely are. They are the [color=red]dart-poison[/color] frogs of[color=red] C[/color]entral and South America. Look at [color=red]their[/color] [color=red]striking[/color] colors, often [color=red]yellow with black stripes or deep blue with black spots[/color]. Beyond being nice to look at, [color=red]these markings[/color] have a purpose: they warm the predators that [color=red]these frogs[/color] are poisonous. [color=red]When threatened[/color], these frogs [b]secrete[/b] a substance through their skin that would [color=red]easily[/color] kill [color=red]whatever[/color] animal might try to eat them. Their bright color[color=red]s [/color]communicate [color=red]this[/color], [color=red]and[/color] so [color=red]most[/color] animals tend not to hurt them. Now speak [color=red]of[/color] hunting, [color=red]for centuries[/color], these frogs [color=red]were sought after by hunters[/color]. As you [color=red]might[/color] think, the hunters didn’t want to eat the frog[color=red]s[/color], but rather they [color=red]captured[/color] them for their poison. They would add [color=red]the[/color] poison to the tip of [color=red]their[/color] hunting arrows. Of course, nowadays most hunters use guns. These days, dart-poison frogs are of less [color=red]interest[/color] to hunters than to medical researchers. Researchers believe that they can make a new heart medicine [color=red]from[/color] the poison, because it acts [color=red]as a stimulant on[/color] the body’s [b]nervous[/b] system. Researchers think that they could use it to stimulate weak heart. There is, however, a problem with doing research on [color=red]these frogs[/color]. [color=red]Those that are caught in the wild[/color] will produce their poison until [color=red]they[/color] die, however, those that are[color=red] born in captivity[/color], like the ones you see here, will not produce any poison at all.

[font=Tahoma][size=12pt]13 Raptor[/size][/font]4KD^J6v/BlI&G0z
[font=Tahoma][size=12pt]As Dr. Miller mentioned, we’re trying to recruit volunteers for the [color=red]Hawk Mountain Sanctuary[/color]. But before we get into the [color=red]details[/color] of the volunteer program, I’d [color=red]just[/color] like to tell you a little about what we do there. One of our main jobs is to keep [color=red]detailed records[/color] [color=red]of[/color] the migration [color=red]patterns of raptors[/color]. For those of you who don’t know, raptors are birds of prey, like hawks and [b]eagles[/b]. Between [color=red]August[/color] and December, we see around twenty different species migrating from Canada [color=red]and[/color] New England, about twenty thousand birds. Part of what attracts them to Hawk Mountain is the location[color=red] on the east ridge of the Appalachian Mountains[/color]. What happens is that the sun warms the [color=red]ridge[/color] in such a way that air currents are formed. The birds just sort of[color=red] glide along on[/color] the air, so they use up very little energy. As volunteers you will be helping [color=red]us[/color] keeping accurate [color=red]counts[/color] of [color=red]the[/color] raptors. Any drop in number [color=red]could[/color] mean something[color=red]’s[/color] [color=red]gone[/color] wrong [color=red]in[/color] the environment because of pesticides or disease even hunting. We just [color=red]had a scare with the broad-winged[/color] hawks. Their numbers have dropped [color=red]drastically[/color] over the last ten years. It [color=red]was[/color] suggested [color=red]that[/color] the birds may have changed their [b]migratory[/b] route. So for eleven days, we had several hundred volunteers, stationed every five miles, to observe and [color=red]count[/color]. And sure enough, they discovered that instead of [color=red]hugging the Appalachians[/color] as they’d always done, the broad wings were [color=red]cutting a wide path over the Delaware River[/color]. Needless to say, we were greatly [b]relieved[/b]. [/size][/font]
