| Allelopathy is an adaptation plants use to chemically compete with other plants and can occur both interspecifically and intraspecifically. |
| In the eastern United States, wintering Red-headed and Red-bellied Woodpeckers will defend territories interspecifically. |
| Due to the observed differences in morphology, some of the details of these interspecifically variable characters were not included in the generic diagnosis given above. |
| This is demonstrated by the negative correlations between antipredation behavior and antipredation related morphology in snails, intraspecifically and interspecifically. |
| That effect may occur interspecifically as well, in that species that carry higher relative fuel loads are also more at risk than species with lower relative fuel loads. |
