Fig. 1. Mean (+ SE) number of Scyphophorus acupunctatus captured per trap baited with different amounts of fresh agave tissue in 2 trials. The 1st trial was performed from 18 Jan to 8 Feb 2013 (A), while the 2nd trial was carried out from 11 Apr to 23 May 2013 (B). Bars with the same letter are not significantly different (Tukey's, a = 0.05).

Fig. 2 in Effect of food deprivation on hydrilla tip mining midge survival and subsequent development

Fig. 2. Effect of starvation post-hatch on the eclosion of Cricotopus lebetis adults from hydrilla (Hydrilla verticillata) stems in test tubes. Midge eclosion was defined as observing an adult C. lebetis in the test tube. Bars represent mean percentage midge eclosion ± standard error of the mean. Statistical differences between the midge eclosion observed afer different starvation periods post-hatch are indicated by different letters.

Fig. 1 in Effect of food deprivation on hydrilla tip mining midge survival and subsequent development

Fig. 1. Effect of food deprivation on larval survival of the hydrilla tip mining midge, Cricotopus lebetis. Number of larvae alive recorded for each day posthatch in 96-well plates. Mean percentage survival ± standard error of the mean. The number of larvae alive decreased significantly each day (P <0.05).

Fig. 1 in Distant-dependent capture probabilities of Mediterranean and oriental fruit flies (Diptera: Tephritidae) in a food-based trap in a Hawaiian mango orchard

Fig. 1. Number of captures (A) and percentage of captures (B: captures divided by released) for Bactrocera dorsalis released from 5, 10, or 20 m from a centrally located trap baited with torula yeast borax solution. For a given replicate, 200 individuals of each sex were released. Symbols represent means with standard error (N = 7 replicates in all cases). Within each sex, numbers of captures differed significantly between distances marked with different upper case letters. Within a distance, numbers of captures differed significantly between the sexes if marked with different lower case letters.

Fig. 3 in The role of cladocerans in green and brown food web coupling

Fig. 3. The proportion of the contribution of POC, phytoplankton, and biofilm to cladoceran biomass in the three PIAP lagoons. Boxplots show the quartiles of 97.5%, 75%, 50%, 25%, and 2.5%. The lower and upper boxes indicate the 25% and 50% quartiles. Likewise, the lower and upper vertical lines indicate the 97.5% and 2.5% quartiles and the horizontal lines show the mode of contribution.

Fig. 2 in Trophic relationships in fish assemblages of Neotropical floodplain lakes: selectivity and feeding overlap mediated by food availability

Fig. 2. Ordination by principal coordinate analysis (PCoA) of the food resource availability for six floodplain lakes along the Upper Paraná River, Paraná-Mato Grosso do Sul. AQI = aquatic insects; OAI = other aquatic invertebrates; OTI = other terrestrial invertebrates; PLA = plants; TRI = terrestrial insects.

Fig.5. Relationship between the mean of the proportional overlap Index (IS) and the scores of the first PCoA axis of resource availability in isolated floodplain lakes along the upper Paraná River.Values of IS closer to 1 indicates greater diet overlap. The mean IS was calculated based on individuals of 3 (ZÉ = ZÉ Marinho), 7 (Carioca = Car), 4 (TiÃo = Tia), 5 (Genipapo = Gen), 2 (CidÃo = Cid) and 5 species (Canal = Can).AQI = aquatic insects; PLA = plants.
