Environmentally similar but isolated regions have distinct assemblages of mammals and birds

He suggested, and showed evidence that sea level and climate change over time, and what we see now may not have been a long time ago. This helped explain why we see the distribution of species we see today.

• The total number of species (or other taxonomic level, or genetic varriation) in a given location.

• •Alpha diversity: diversity within a given region
• •Beta diversity: diversity between different regions
• •Gamma diversity: total area biodiversity
