Human populations near the a quarter(equator) involve(evolved) dark skin over many generations because of the exposure to the serious(fierce) rays of the Sun. A seminal(silimar) phenomenal has also occurred in other parts of animal kingdom, the African grass mouse is a good example. Most mice are nocturnal, but African mouse is active during daylight hours. This means that it spends its days searching for food in semi-dry bush and scorp(scrub) habitats of eastern and southern of Africa. Its fur is striped, like a mice which helps it blend in with its environment, because it spends a lot of time in the tense tropical sun, the grass mouse has also evolved two separate safe guards against the sun’s ultraviolet radiation. First, like the population of humans in this region of the world, the skin of mouse contains a lot of melanin or dark pigment. Second and quite unusual, this mouse has a layer of melanin-pigmented tissue between its scope(skull) and the skin. This unique cap provides an extra measure of protection for the grace mouse and other type of African mouse like rodents that active during the day. The only other specials(species) scientists identify with the same sort of skull is the quite(white) tent of making bat of the central of the American tropics. Although these bats sleeping in the day, they do so curled up with their heads exposed in the sun.

8 m) J6 n, ?1 Y, FOK, in the last class we talked about the classification of trees, and we ended up with a basic$ _0 Q4 ^- Q g& L
description of angiosperms. You remember that those are plants with true flowers and seeds that develope inside fruits, the common broadly(broadleaf) trees we have on campus fall into this categeory(category), but our pines do not. Now, I hope you all followed my advice and wore 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 broadleaf trees we have in front of us, I am sure you have all noticed this brand(big) tree behind the(next to) hall. It is a black walnut that must be 80 feet tall. As a matter of fact there is a plack(plaque) identifying it as the tallest black walnut in the state. And from here we can see the beautiful artial(archway) of trees at the commons, they have American elms…. The ones along the commons were planted when the college was founded 120 years ago. They have the distinctive dark green leaves that look sides(lopsided) because the two sides of the leaf are unequal. I want you to notice the elm right outside Jackson Hall… Some of its leaves have withered and turned yellow, maybe due to the Dutch elm diseases. Only a few branches seem affected so far, but if this tree is sick, it will have to be call down. Well let’s move on and I will describe what we see as we go.

1 V- |: Q; Z; B- E+ h# uToday I want to talk to you about warsp(wasps) and their nests. You recalled that biologists divide species warsp into two groups: solitary and social. Solitary warsp, as the name implies, do not live together with other warsps, in most species the male and female get together only to made(mate). And then females does all the work of building the nest and providing food for offspring by herself. Solitary wasps makes nest in the ground and they separate the timber(chambers) for individual offspring with bits of grass, stone, or mod(mud) whatever is handy . What about social warsps, they form community and work together to build and maintain the nest. A nest begins in the spring when a fertile female, called the queen, builds the first few conponents(compartments) of the nest and lays eggs. The first offspring are small females that can not lay eggs, these female called workers athen bulit a lot of new compartments, and queen lays more eggs. They also care for the new offsprings and defend the nest with stingers, by the way, only female warsps have stingers. Most social warsps make nests of papper, the females produce the paper by chewing up plant fibers or old wood. They spread the paper in thin layers to make cells in which the queen lays eggs, most of you, have been seen these nests susbend(suspended) from trees, they may also be built on the ground(underground), in the band(abandoned) rodent burrows
