FIGURE 6 in Ortalis remota: a forgotten and critically endangered species of chachalaca (Galliformes: Cracidae) from Eastern Brazil

FIGURE 6. Satellite image showing the great habitat alteration on the upper Parana River system—the range of Ortalis remota—due to the construction of dams and deforestation. Red lines: major dams; lemon-yellow symbols: localities where O. remota was recorded (star = type-locality). The major rivers mentioned in the text are indicated by their names; the inset map is the same as Figure 1. Based on image by Google Earth (Feb. 2017).

Inset shows a map of West Africa showing the location of the Atewa Range in Ghana (upper left), known localities of Conraua sagyimase sp. nov. are shown in red and know localities of Conraua derooi in yellow. Stars indicate type localities. Altitudinal range is indicated with shading from lowlands (light) to high elevation (dark). Sources: OpenStreetMap (2020), U.S. Geological Survey (2020).

Fig. 1 in A Stable Isotope Investigation into the Feeding Behavior of Brychius Hungerfordi Spangler (Coleoptera: Haliplidae), a Federally Endangered Crawling Water Beetle

Fig. 1. Keeling Plots of carbon (a) and nitrogen (b) signals against the reciprocal of the mass. The y-intercept is the isotopic value of the source dominating the mixture of Cocconeis and Dichotomosiphon and agrees well with the observed isotopic signature of Dichotomosiphon.

Fig. 8 in Efficient New Above-Ground Bucket Traps Produce Comparable Data to that of Standard Transects for the Endangered American Burying Beetle,Nicrophorus AmericanusOlivier (Coleoptera: Silphidae)

Fig. 8. Suggested improvements to above-ground bucket trap design using a wooden rain cover and landing pad to reduce disturbances from scavengers, reduce maintenance, and increase bait-life.

Fig. 5 in Efficient New Above-Ground Bucket Traps Produce Comparable Data to that of Standard Transects for the Endangered American Burying Beetle,Nicrophorus AmericanusOlivier (Coleoptera: Silphidae)

Fig. 5. Average differences in abundance estimates for Nicrophorus americanus between methods using various sample-effort conversion rates (n = 20). Normalized average differences are mean differences divided by their standard deviations to provide a standardized scale for comparisons because abundance estimates—and therefore differences between them—are inherently smaller when trap-nights are artificially increased.

Fig. 4 in Efficient New Above-Ground Bucket Traps Produce Comparable Data to that of Standard Transects for the Endangered American Burying Beetle,Nicrophorus AmericanusOlivier (Coleoptera: Silphidae)

Fig. 4. Sample site layout (n = 28) showing 800-m site buffers (open circles). The order in which trap methods were used during the two sample periods at each site included buckets then transects (circles), transects then buckets (squares), and transects during both sample periods at control sites (triangles).

Fig. 7 in Efficient New Above-Ground Bucket Traps Produce Comparable Data to that of Standard Transects for the Endangered American Burying Beetle,Nicrophorus AmericanusOlivier (Coleoptera: Silphidae)

Fig. 7. ANOVA group means showing the relationship between beetle captures and the numbers of disturbed traps. Beetle abundance values were ranked for the three sample nights at each site such that increasing rank represented increasing abundance. Precision was low in groups 4 and 5 due to small sample sizes (n = 6 and n = 4, respectively).
