What are two ways in which water availability affects the distibution and abundance of species in Australia?
To understand how water availability affects the distribution and abundance of species in Australia, we can look into two main factors: precipitation patterns and water sources. Here's how you can explore these aspects:
1. Precipitation Patterns:
a. Analyze rainfall data: You can study historical rainfall patterns in different regions of Australia to understand how water availability varies across the country. Look for datasets provided by meteorological agencies, which often have rainfall records over extended periods.
b. Examine impact on ecosystems: Once you have rainfall data, consider its impact on various ecosystems. Identify areas with high rainfall, such as the tropical regions of the north, where water abundance supports diverse species. Compare this with arid and semi-arid regions in the center and west, which face water scarcity, leading to specific adaptations and limited species diversity.
2. Water Sources:
a. Investigate surface water: Explore the presence and variability of surface water bodies such as rivers, lakes, and wetlands using maps or satellite imagery. Understand how water availability affects the distribution of species that depend on these water sources for survival.
b. Study groundwater accessibility: Assess the availability of groundwater by examining geological surveys or hydrological studies. Groundwater can play a significant role in sustaining species in areas with limited surface water. Look for areas where species concentration aligns with accessible groundwater sources.
By considering these aspects of precipitation patterns and water sources, you can gain insights into how water availability influences species distribution and abundance in different parts of Australia.
