Today in our environmental science lecture, we're discussing the impact of urban development on local wildlife. A recent study in Melbourne observed that the presence of community gardens significantly increased the number of native bee species in surrounding areas. However, the researchers noted that these gardens alone are not sufficient. They recommend a network of green spaces, including rooftop gardens and tree-lined streets, to support biodiversity. Interestingly, the study found that the size of the garden mattered less than the variety of flowering plants. This suggests that even small, well-planned gardens can attract diverse pollinators, but only if they are connected to other habitats.
❓ Según la conferencia, ¿qué descubrió el estudio en Melbourne sobre los jardines comunitarios?
A. Son el único factor necesario para aumentar las especies de abejas nativas.
B. Su tamaño es más importante que la variedad de plantas.
C. Ayudan a las abejas nativas, pero necesitan estar conectados con otros espacios verdes.
D. No tienen ningún efecto sobre la vida silvestre en áreas urbanas.
✅ 正确答案
They help native bees but need to be connected to other green spaces.
