Mountaineers have noted that as they climb, for example, up to the 12,633–foot Humphreys Peak in the San Francisco Peaks in Arizona, plant life changes radically. Starting among the cacti of the Sonoran Desert, one climbs into a pine forest at 7,000 feet and a treeless alpine tundra at the summit. It may seem that plants at a given altitude are associated in what can be called “communities” – groupings of interacting species. The idea is that over time, plants that require particular climate and soil conditions come to live in the same places, and hence are frequently to be found together. Scientists who study the history of plant life are known as paleobotanists, or paleobots for short. They build up a picture of how groups of plants have responded to climate changes and how ecosystems develop. But are these associations, which are real in the present, permanent?

A great natural experiment took place on this planet between 25,000 and 10,000 years ago, when small changes in the earth’s orbit and axis of rotation caused great sheets of ice to spread from the poles. These glaciers covered much of North America and Europe to depths of up to two miles, and then, as the climate warmed, they retreated. During this retreat, they left behind newly uncovered land for living things to colonize, and as those living things moved in they laid down a record we can read now. As the ice retreated and plants started to grow near a lake, they would release pollen. Some would fall into the lake, sink to the bottom, and be incorporated into the sediment. By drilling into the lake bottom it is possible to read the record of successive plant life around the lake. The fossil record seems clear; there is little or no evidence that entire groups of plants moved north together. Things that lived together in the past don’t live together now, and things that live together now didn’t live together in the past. Each individual organism moved at its own pace. The fossil record seems to be telling us that we should be thinking about preserving species by giving them room to maneuver – to respond to environmental changes.

Which of the following can be inferred from the passage?

A. That the migratory patterns of plants are dependent upon changes in climate

B. That current associations of plants are similar to those in the past

C. That modern conservation methods should consider the migratory patterns of plants

D. That another ice age is likely to occur at some time

Điều gì có thể được suy ra từ đoạn văn?

A. Các kiểu di cư của thực vật phụ thuộc vào sự thay đổi của khí hậu.

B. Các quần thể thực vật hiện nay tương tự như trong quá khứ.

C. Phương pháp bảo tồn hiện đại nên xem xét các mô hình di cư của thực vật.

D. Một kỷ băng hà khác có khả năng xảy ra vào một lúc nào đó.

Thông tin: Each individual organism moved at its own pace. The fossil record seems to be telling us that we should be thinking about preserving species by giving them room to maneuver – to respond to environmental changes.

Tạm dịch: Mỗi sinh vật riêng lẻ di chuyển theo tốc độ riêng của nó. Mẫu hóa thạch dường như đang nói với chúng ta rằng chúng ta nên suy nghĩ về việc bảo tồn các loài bằng cách cho chúng cơ hội để vận động – để thích ứng với những thay đổi môi trường.

Dịch bài đọc:

Những người leo núi đã chú ý rằng khi họ leo núi, ví dụ, lên đến đỉnh Humphreys cao 12,633 feet ở Đỉnh San Francisco ở Arizona, đời sống thực vật thay đổi hoàn toàn. Bắt đầu giữa những cây xương rồng của sa mạc Sonoran, một người leo lên một khu rừng thông ở độ cao 7,000 feet và một lãnh nguyên núi cao vô tận ở đỉnh núi. Dường như các loài thực vật ở độ cao nhất định có liên quan đến những gì có thể được gọi là “quần xã” – nhóm các loài tương tác. Ý tưởng là theo thời gian, các loài thực vật đòi hỏi điều kiện khí hậu và đất đai đặc biệt đến sống ở cùng một nơi, và do đó thường được tìm thấy cùng nhau. Các nhà khoa học nghiên cứu về lịch sử của đời sống thực vật được gọi là các nhà cổ sinh vật học (paleobotanists), hay viết tắt là “paleobots”. Họ phác họa nên một bức tranh về cách các nhóm thực vật đã ứng phó với biến đổi khí hậu và cách các hệ sinh thái phát triển. Nhưng những mối quan hệ đang xảy ra trên thực tế này có kéo dài mãi mãi?

Một thí nghiệm tự nhiên tuyệt vời đã diễn ra trên hành tinh này từ giữa 25,000 đến 10,000 năm trước, khi những thay đổi nhỏ trong quỹ đạo và trục quay của Trái đất khiến những tảng băng lớn lan ra từ các cực. Những dòng sông băng bao phủ phần lớn Bắc Mỹ và châu Âu tới độ sâu lên đến hai dặm, và sau đó, khi khí hậu ấm lên, chúng tan ra. Trong suốt quá trình tan chảy, chúng đã bỏ lại vùng đất mới chưa được khám phá để sinh vật sống, và khi những sinh vật đó chuyển đến chúng đã lập một kỷ lục chúng ta có thể đọc ngay bây giờ. Khi băng tan và thực vật bắt đầu mọc gần hồ, chúng sẽ tỏa ra phấn hoa. Một số sẽ rơi xuống hồ, chìm xuống đáy và tạo thành trầm tích. Bằng cách khoan vào đáy hồ, người ta có thể đọc được sự phát triển của đời sống thực vật kế tiếp quanh hồ. Mẫu hóa thạch có vẻ rõ ràng; có rất ít hoặc không có bằng chứng cho thấy toàn bộ các nhóm thực vật di chuyển về phía bắc cùng nhau. Những thứ sống cùng nhau trong quá khứ hiện đang không sống cùng nhau và những thứ sống cùng nhau bây giờ đã không sống cùng nhau trong quá khứ. Mỗi sinh vật riêng lẻ di chuyển theo tốc độ riêng của nó. Mẫu hóa thạch dường như đang nói với chúng ta rằng chúng ta nên suy nghĩ về việc bảo tồn các loài bằng cách cho chúng cơ hội để vận động – để thích ứng với những thay đổi môi trường.
