To continue our unit on biodiversity in forest ecology, let’s consider how some squirrels contribute to the healthy diversity of forests through the effective spreading of seeds. Animals that hide seeds contribute to seed survival, which makes the growth of healthy new trees possible. So let’s review what we know about squirrels. Squirrels are among the most diverse mammals with around 280 species, and they share the behavior of saving seeds for later consumption. Squirrels are rodents, a group that includes rats, mice, and beavers. The teeth of rodents constantly grow and must be worn down through chewing.
To ensure their survival, squirrels gather and save as much food as possible. Researchers describe two seed saving methods：storing and scattering. Storing is when squirrels bury seeds together underground for long－term storage. This action does not contribute greatly to forest development, whereas the other behavior, called scattering, does.
So what is scattering？ Scattering is when squirrels hide each seed separately under leaves on the ground over a wide area far from their original source. Squirrels only eat a small number of the seeds they hide. The rest of the scattered seeds may get stolen by other squirrels or competing animals while some are merely forgotten. It is these forgotten scattered seeds that contribute most to healthy diverse forests.
However, in order for the scattered seeds to become trees, two additional conditions are required. First, the seeds scattered by squirrels must be distant from other rival seeds originating from the same parent tree. Second, they must also be far away from older trees that may be diseased. Under these conditions, seeds will grow successfully and this will lead to the healthy expansion of forests.

あなたは、講義の要約を書く準備をしています。グループのメンバーA、Bと口頭で内容を確認しています。
Student A：
When squirrels hide seeds too close to parent or diseased trees, it’s less likely that healthy diverse forests will develop.
Student B：
Because squirrels eat only some of the seeds they have scattered, the rest have the potential to become trees.

あなたは、JoeとMayとの三人で、後の図表を見ながら、講義の内容についてディスカッションの準備をしています。
May：The graph from this experimental study shows the seed－spreading rate by squirrels in forests.
Joe：It looks like the amount of spreading varies depending on whether mice are present.
May：That’s because when squirrels and mice are together, squirrels need to scatter and hide more seeds in case mice try to take them.
講義、JoeとMayの会話及び図表の内容からどのようなことが言えるか、最も適切なものを、四つの選択肢のうちから一つ選びなさい。

講義、JoeとMayの会話及び図表の内容からどのようなことが言えるか、最も適切なものを、四つの選択肢のうちから一つ選びなさい。
- When competing animals are present, squirrel behavior changes and forest growth increases.
- When mice and squirrels compete for food, the growth of forests is limited.
- When mice and squirrels store seeds underground, seeds are more likely to become trees.
- When there are no competing animals, squirrels gather more seeds, which helps forest growth.
