What does "Species Distribution Models" mean?
Table of Contents
Species Distribution Models (SDMs) are tools used by scientists to show where different plants and animals are likely to live. These models look at factors like climate and the environment to predict where species can be found.
Importance of SDMs
With many species facing extinction due to climate change and other threats, SDMs help us understand how these changes impact habitats. By knowing where species thrive, we can better protect them and their ecosystems.
Data Sources
Initially, SDMs faced challenges because there weren't enough observations of species. However, with the help of citizen science—where everyday people contribute data—more information is available. This has made the models more reliable.
Class Imbalance Issue
One big issue with these models is that some species are much rarer than others. This imbalance can lead to less attention for the rare species, which are often crucial for conservation. To improve the situation, researchers are developing better ways to train these models so that they pay more attention to rare species.
Future Predictions
SDMs are also useful for predicting how climate change will affect species in the future. By considering different scenarios, scientists can estimate how species distributions may shift over time. This information helps in planning conservation efforts and understanding the overall impact of climate change on biodiversity.
Conclusion
Overall, Species Distribution Models are essential for studying and protecting wildlife. They help scientists understand where species live and how changes in the environment can affect them, guiding efforts to save those most at risk.
