1.The scientific study included all biota, every animal and plant in the forest.

2 Mary knew that the birds were members of the same species because they

were able to breed.

3. The research team was concerned about an illness spreading among the squirrel

population.

4 Luke studied biotic factors, produced by living  organisms.

5 A healthy deer population was introduced to the forest in order to promote

genetic diversity.

6 Once trees were replanted, the animals were returned to their natural habitat.

Forester: Thanks for coming out to the forest today, Jana.

Gracias por venir al bosque hoy, Jana.

Ecologist: Thank you for the invitation. I’m looking forward to seeing the new growth.

Gracias por la invitación. Espero ver el nuevo crecimiento.

Forester: I think that you will be pleased by the improvements in the 1) ecosystem.

Creo que le agradarán las mejoras en el ecosistema.

Ecologist: Your company has done a lot of work through the 2) replanting program.

Forester: Yes. But that’s just one 3) component of the work our scientists are doing.

Si. Pero ese es solo un componente del trabajo que están haciendo nuestros científicos.

Ecologist: What else are they working on? Tell me about it.

Forester: For one thing, our researchers are making efforts to 4) monitor biodiversity.

Ecologist: How do they do that?

Forester: They monitor several 5) species, including plants and animals.

Ecologist: Are they finding rising population numbers as you replant trees?

¿Están encontrando ellos que los números de la población están aumentando mientras replantan los árboles?

Forester: Yes. They are finding more 6) genetic diversity among bird populations, too.

Si, ellos están encontrando más diversidad genética entre las poblaciones de pájaros, también.

Ecologist: That’s great news. It means that the bird populations will be healthier overall.

Eso son buenas noticias. Esro significa que las.. serán
