R seed sorts and genus of visitor. Video measurements: elapsed time
R seed sorts and genus of visitor. Video measurements: elapsed time per visit. To evaluate elapsed time (time that visitors invest removing seed from dishes), we constructed linear mixed models with all the nlme package in R [24, 22]. We employed the logtransformed elapsed time because the response variable, with the fixed effects of genus, seed form, and dish form. We employed the random intercept of station only (season nested inside station did not strengthen model match). We removed visitation by Sylvilagus as a consequence of low sample sizes. Because of this, the evaluation evaluating time spent removing seed focuses on preference for dish and seed variety among the 3 rodent genera: Chaetodipus, Peromyscus, and Dipodomys. We constructed exactly the same seven models as described for “Video measurements: quantity of visits” and employed AIC to pick the strongest model. We performed leastsquares suggests and contrasts to evaluate variations inside the number of visits for seed sorts and genus of visitor. Mass of seed MedChemExpress PF-04929113 (Mesylate) removal with video measurements. To evaluate seed removal making use of video predictors, we took a linear mixed effects approach applying the nlme package in R [24, 22]. We applied mass of seed removed (g) as the response variable, with presence of every single genus, seed variety, and dish type as the fixed effects. We made use of season nested inside station because the random intercept term. Lastly, we added variance structures to account for heteroscedasticity for Sylvilagus presence and season. We made use of leastsquares indicates and contrasts to evaluate variations in seed removal involving genera. We compared ten models, that are listed and described in Table . Apart from the interactions among seed variety, dish type, and genera, 
this evaluation also incorporates applicable genusgenus interactions (it was not doable to include a genusgenus interaction for genera thatPLOS One DOI:0.37journal.pone.065024 October 20,6 Remote Cameras and Seed PredationTable . Model comparisons for linear mixedeffects model applying mass of seed removed as the response variable. Every model incorporated the random effect of season nested inside station, and also a variance structure to account for heteroscedasticity for Sylvilagus presence and season. Delta AIC values indicate the distinction in between the highest performing model and every on the competing models.
