Dark organisms, for example, tend to absorb heat more quickly than China lighter individuals, which could influence their responses to temperature. Therefore, 3College of Marine and Environmental Science, James Cook University, Townsville, temperature- related traits such as morphology may affect patterns of species abun- QLD, Australia dance, richness, and community assembly across a broad range of spatial scales.
