Figure 1.
Effects of lamp type and weather parameters on moth species richness (a) and abundance (b).
The parameter estimates and 95% CI are derived from model averaging. All estimates are on a comparable scale due to standardisation of the models.
Table 1.
Standardised parameter estimates for the models of the effects of lamp type and climate on trap performance including standard error (SE), 95% confidence interval (CI) and relative variable importance for moth species richness and abundance.
Figure 2.
Nightly catches of moth species (a) and individuals (b).
Different symbols represent different light sources (○ = 250W; • = 40W) and the line represents temperature.
Figure 3.
The number of species caught in each month with each light source, and the number of shared species between consecutive months.
The Jaccard and Simpson indices reflect similarities in species composition and species richness, respectively. Total species richness for the period was 372 species.
Figure 4.
Proportion of species with a peak in abundance in each month.
Figure 5.
Sample-based rarefaction curves with 95% confidence intervals generated from data obtained using four sampling strategies and the traps with a 40 W black light bulb (a) and a 250 W mercury lamp (b).
The strategies were: ALL – sampling during all nights (n = 225); SUMMER – sampling only in nights in June, July and August (n = 92); WARMEST SUMMER – sampling only in the warmest nights in June, July and August (n = 23); and WARMEST MONTHLY – sampling only in the warmest nights in each month (n = 56). Warm nights belonged to the warmest quartile of each time period. The figure is restricted to a maximum of 100 sample nights.
