Hypothesis
How effective and consistent are different indicator groups in representing mammal species in the Brazilian Cerrado and Atlantic Forest?
Conclusion
Restricted-range species are the most effective and consistent indicator group for representing mammal diversity in both the Cerrado and Atlantic Forest.
Supporting Evidence
- Restricted-range species consistently captured high diversity of mammals in both biodiversity hotspots.
- Indicator groups required less than 2% of the area to effectively represent target species.
- Random species sets performed worse than selected indicator groups in representing mammal diversity.
Takeaway
Some groups of animals can help scientists decide where to protect nature, but only one group, the restricted-range species, works well in different places.
Methodology
The study examined nine indicator groups' effectiveness in representing mammal species across two biodiversity hotspots by comparing their performance in site selection.
Potential Biases
The use of range maps may overestimate species distributions, affecting the effectiveness of indicator groups.
Limitations
The study's results are based on a limited conservation goal and may not account for other important biodiversity aspects.
Participant Demographics
The study focused on terrestrial mammals in the Brazilian Cerrado and Atlantic Forest.
