You will hear part of a lecture about the study on desert animals. First, you have some time to look at questions thirty-one to forty. 00:00:22,240 Now listen carefully and answer questions thirty-one to forty. 00:00:52,900 Good morning and welcome to the Westgate Zoo's special presentation on desert animals. We would like to thank you for attending. We appreciate the opportunity to educate as many people as we can on the importance of the desert environment to our planet. 00:01:10,500 Many people think that the desert is barren and devoid of life. 00:01:15,260 However, we are here to convince you today that that's far from true and that the deserts are in fact beautiful places teeming with life. 00:01:26,940 As you know, the fine balance of ecosystems is an essential part of our planet. In every environment, from the desert to the jungle to the deepest ocean, we see that species rely on each other, and any disturbance to one member of an ecosystem has a ripple effect on everything else. Today, the first topic I would like to share with you is how two different species react to each other's behavior, namely their interaction. When it comes to desert, we tend to think that in such a sterile environment, every creature will fight fiercely with each other for food and water since they are so scarce. 00:02:10,240 That's true to some extent. Both things can also be different. Here we can bring quite a few examples on how one species can coexist with another in the desert. 00:02:22,620 One excellent example is mice and lizards. They are animals of a similar size and treat each other with a wary tolerance. 00:02:31,840 Neither will attack or eat the other, but they do share something in common: their food source. Although mice will also eat seeds and plants, and lizards sometimes eat other small lizards, their common food source is insects such as spiders, ants, and other bugs, which are high in protein and other nutrients as well. So they don't need to hunt for food until they get hungry next time. Most of the time, the two species will not interfere with each other's eating preferences. However, they do compete for food at times, but it rarely results in a direct fight as there is usually plenty of food for both of them. 00:03:19,380 Now let's undertake our second topic. Instead of studying how two species get along with each other or how they are similar to one another, we will explore for more information through comparison. This time we have two completely contrasting species, and we will see the way in which both species use their own way of adapting to a changing environment and even how they find additional resources in harsh environments. 00:03:48,650 The example here is kangaroos and locusts, both of which have adapted well to the changing environment. 00:03:56,220 Rather than reducing in number like many animals when humans encroach on their habitat, kangaroos can live and feed just as well on golf courses and lawns as they can on their own native grasses. 00:04:11,240 Incredibly, the population of kangaroos in Australia has increased dramatically to nearly forty-four million. In some parts, kangaroos are even culled in large numbers because they have become a pest. In a similar way, as the areas being used for farmland have increased, locusts have taken advantage of the extra food, much to the dismay of the farmers. 00:04:37,580 And studies have shown that the size of the creature is seven percent larger than ten years ago. So as you can see in these two cases, some species are able to adapt very well to living with the changing environment. On another topic now, we often hear about symbiotic or cooperative relationships between species where they are mutually beneficial to each other. You have probably heard about this kind of cooperation in species such as sea anemones and clownfish, sharks and canna fish, as well as leafcutter ants and fungus. 00:05:16,320 Well, the example I have for you today is fire ants and some plants. 00:05:22,940 The former can benefit from the protection offered by the latter. 00:05:27,510 The plants have ways to ensure that ants defend them from attacks and also spread their seeds. 00:05:35,540 The ants look for various kinds of seeds, and some seeds are not completely consumed, meaning that the kernels of the seeds are scattered around their nests, effectively spreading the seeds to grow into new plants. 00:05:51,520 Studies have shown that the amount of ants can be doubled when they are near these particular plants simply because of the shelter they provide. 00:06:00,700 This is a terrific example of how species can work together to be mutually beneficial, and this is something humans need to consider more in their own environments. 00:06:12,280 Well, I hope that my talk has helped open your eyes to the beauty that the desert holds. Are there any questions? 00:06:20,620 That's the end of part four. You now have half a minute to check your answers. ## 题目与答案 ### 31. | Topic | Aim | Conclusions | | --- | --- | --- | | The 31_____ between two species | ·To see how species 32..... in a desert
