Table 3.
Comparison of models used to explain viral richness, ectoparasite and endoparasite species richness in Southeast Asian bats using independent contrasts. The initial model included the following variables: sampling effort (number of hosts sampled for a given virus: hsv); investigating effort (number of publications on parasites for a given host: pubn); host body mass (body mass); colony size (colony); breeding seasons (breeding); geographical distribution range size (range); and shape of the geographical distribution (fragmentation). Models are ranked from the least to the most supported according to corrected Akaike information criteria (AIC).
| Dependent variables | Model ranks | AIC |
|---|---|---|
| Viral richness | Fragmentation + colony + pubn | 31.0 |
| Fragmentation + colony + breeding + pubn | 31.1 | |
| Range + fragmentation + colony + breeding + pubn | 32.6 | |
| Range + fragmentation + colony + breeding + hsv + pubn | 34.3 | |
| Body mass + range + fragmentation + colony + breeding + pubn | 36.2 | |
| Ectoparasite species richness | Body mass + colony + pubn | 98.4 |
| Body mass + colony + breeding + pubn | 99.7 | |
| Body mass + fragmentation + colony + breeding + pubn | 100.8 | |
| Body mass + range + fragmentation + colony + breeding + pubn | 102.3 | |
| Endoparasite species richness | Fragmentation + pubn | 41.3 |
| Body mass + fragmentation + pubn | 42.7 | |
| Body mass + fragmentation + breeding + pubn | 44.6 | |
| Body mass + fragmentation + colony + breeding + pubn | 46.6 | |
| Body mass + range + fragmentation + colony + breeding + pubn | 48.6 | |
