Environmental and disturbance covariates fitted in dynamic occupancy models for mammals detected over a period of 8 years in the Udzungwa Mountains of Tanzania
| Variable | Notation | Description | Hypotheses |
|---|---|---|---|
| Elevation | ELEV | Elevation of camera‐trapping sites (m a.s.l.). | Species‐specific variability in response to elevation as proxy for habitat type, for example, positive effect on interior species (Sanje mangabey, Abbott's duiker). |
| Elevation squared | ELEV2 | Square term for the effect of elevation. | Mid‐altitude peaks in species‐specific distribution for species ranging across the elevation gradient (e.g., suni). |
| N of snares | SNARES | The number of snares for illegal hunting collected by the field team during the deployment of each array of camera traps in every sampling season. | Negative effect especially for species most targeted by hunting, for example, forest antelopes. |
| Firewood collection activity | BAN | Binary year‐specific covariate, which describes the state of the forest in terms of firewood collection activity (allowed/not allowed). Firewood collection was allowed in the forest until 2011. | Positive effect for species preferring edge/low elevation species (e.g., Harvey's duiker, suni) |
The hypothesized relationship is also indicated.
