“…Of the seven silphid beetle species identified, they found that three Nicrophorus species, including N. marginatus, were more abundant in loessal soils and two Nicrophorus species were more abundant in granitic soils. Similar niche partitioning associated with soil type was found for several Nebraska burying beetles in areas without ABB presence (Bishop et al, 2002). Soil texture candidate variables were not part of the best subset of variables for the Loess Canyon's ABB suitability models and the region has high silt content, which is very different from the sandy soils of the Sandhills.…”

“…These differences could be attributed to soil texture and compaction or other land cover variables. Additional information on the distribution and density of other carrion beetles found in the Sandhills ecoregion could be utilized in future modelling efforts because of the possible influence of niche partitioning (Bishop et al, 2002;Dobesh, 2007). Crawford & Hoagland (2010) pointed out a number of difficulties in modelling ABB occurrence, such as problems determining grain size (i.e.…”

“…Moreover, for United States Fish and Wildlife Service (USFWS) personnel involved in making decisions about proposed habitat alterations, the identification of basic habitat affinities of ABBs, even within localized regions, would be very useful. Bishop et al (2002) found that some carrion beetles in Nebraska showed preference for soil textures and land use, but did not include the ABB in the study. In Oklahoma, Crawford & Hoagland (2010) identified elevation, slope, soil association, surface geology, land cover, forest cover, annual temperature, days below freezing, last growing season day and May precipitation as predictor variables of ABB occurrence using a Maxent model.…”

Conservation efforts leading to the recovery of the federally endangered American burying beetle (ABB), Nicrophorus americanus Olivier, have been challenging because of the unknown causes of its decline, difficulty in establishing habitat requirements, and unclear population distribution across the species' range. Extant populations of this widespread generalist species occur in broadly separated regions of North America with varying habitat characteristics. A habitat suitability model for ABB in the Nebraska Sandhills was developed over the course of 3 years resulting in a final crossvalidated spatial model. The succession of models from 2009 to 2011 indicated that most of the predictive variables stayed constant, but biased sampling and extrapolation areas affected classifier values differently. Variables associated with ABB occurrence were loamy sand, wetland and precipitation. Five variables, loam soil, agriculture, woodland, the average maximum temperature, and urban development, were associated with ABB absence. The 2011 cross-validated model produced an AUC value of 0.82 and provided areas designated as highly likely to support ABBs. By limiting the model extent to the Sandhills ecoregion and using threshold-dependent classifiers, the final habitat suitability model could be an important resource for wildlife managers engaged in the recovery of this habitat generalist.

“…There is a huge literature on contact zones in a multitude of taxa, and many important papers on the influence of environmental factors (e.g. Reinert, 1984a; Bishop et al ., 2002). However, few studies have addressed this relationship spatially, using Geographical Information System (GIS) tools (but see Anderson et al ., 2002; Swenson, 2006), and usually these studies performed over broad regions, such as continents (but see Brito & Crespo, 2002).…”

The current range of European vipers is mostly parapatric but local‐scale allopatric distribution is common and few cases of sympatry are known. In the High Course of Ebro River, northern Spain, there is a contact zone between Vipera aspis, V. latastei, and V. seoanei. Sympatry was detected between aspis and latastei and also specimens with intermediate morphological traits. Presence‐data at a local scale (1 × 1 km) and ecological niche‐based models manipulated in a GIS were used to (1) identify how environmental factors correlate with the distribution of the three vipers and with the location of the sympatry area, and (2) identify potential areas for viper occurrence and sympatry. Ensemble for casting with 10 Maximum Entropy models identified a mixture of topographical (altitude, slope), climatic (precipitation, evapotranspiration, and minimum and maximum temperature), and habitat factors (land cover) as predictors for viper occurrence. Similar predicted probabilities according to the variation of some environmental factors (indicating probable sympatry) were observed only for aspis‐latastei and aspis‐seoanei. In fact, areas of probable occurrence of vipers were generally allopatric but probable sympatry between vipers was identified for aspis‐latastei in 76 UTM 1 × 1 km squares, for aspis‐seoanei in 23 squares, and latastei‐seoanei in two squares. Environmental factors correlate with the location of this contact zone by shaping the species range: some enhance spatial exclusion and constrain distribution to spatially non‐overlapping ranges, while others allow contact between species. The distribution in the contact zone apparently results from the balance between the pressures exerted by the different environmental factors and in the sympatry area probably by interspecific competition. Further ecological and genetical data are needed to evaluate the dynamics of the probable hybrid zone. GIS and niche‐modelling tools proved to be powerful tools to identify environmental factors sustaining the location of contact zones.

“…Other silphid species (e.g. N. orbicollis ) are found in moister areas, such as forests near water, and are active at night; thus, they may have even higher water‐loss rates (Bishop et al ., 2002).…”

High water‐loss rates and rapid dehydration in the burying beetle, Nicrophorus marginatus

During the summer months, there is a high mortality of burying beetle (Coleoptera: Silphidae) species in pitfall traps containing dry soil. The present study investigated the possibility that the burying beetle Nicrophorus marginatus is highly susceptible to death from desiccation. In the laboratory, adult beetles lose 1-5% body mass per hour in low humidity conditions (25-30% relative humidity), depending on temperature. This rate of water-loss results in a 50% mortality within 7-16 h at temperatures between 16 and 28 C. Nicrophorus marginatus produces oral and anal defensive secretions when disturbed but these secretions do not significantly contribute to the high rate of water loss. Beetles readily drink and thus beetles with access to water or in high humidity conditions suffer near zero mortality. For comparison, the similarly sized mesic bess beetle (Coleoptera: Passalidae), Odontotaenius disjunctus, and a large nocturnal tiger beetle (Coleoptera: Cicindelidae), Amblychila cylindriformis, are exposed to dehydrating conditions. Nicrophorus marginatus have higher rates of water-loss (by 26% and 79%, respectively). It is predicted that the diurnal N. marginatus uses behavioural mechanisms to avoid lethal water loss. In the field, N. marginatus displays a strong bimodal activity pattern, avoiding the hottest hours of the day. The significance of these findings is that N. marginatus defies normal predictions of association between water-loss rates and habitat type, and has extended its range into apparently unfavourable habitats despite high water-loss rates. In addition, the results suggest that researchers should provide moisture when studying burying beetles, including the endangered American burying beetle (Nicrophorus americanus).
