Fig. 2 in Carabid Beetle (Coleoptera: Carabidae) Abundance and Habitat Preference in Northeastern São Paulo State, Brazil
Fig. 2. Perceptual map of correspondence analysis showing carabid species occurrence in the forest fragment (traps along transect 10–100 m inside the fragment), at the edge (traps along transect of 1–4 m), and in the crop (traps along transect 10–100 m inside the crop). Carabid species names are abbreviated with the first three letters of their genus and first four letters of the species epithet (see Table 1 for complete species names). Small circle represents the location of carabid species; large circle, square, and plus sign indicate the location of traps in edge, forest fragment and crop, respectively.

Inferring quantitative species interactions of seeds and seed-feeding carabid beetles from ecological survey data
<p>Here, we develop a trait-based approach suitable for creating quantitative networks, i.e. with varying interaction strengths. We applied this method to existing ecological survey data from an arable field of carabid ground beetles (Coleoptera: Carabidae) from pitfall traps and plant seeds from seed rain traps. We used existing data in the literature to predict a per-individual interaction cost index from carabid and seed size, based on frequency-dependent prey selection and the energetic intake of seeds by carabids. This was scaled up to the population level to create predicted inferred weighted networks using the sampled abundance of carabids and seeds, energetic intake rates in the literature, and assuming bottom up control. From this we calculated a novel predation pressure ratio which was the predicted seed predation (the sum of interaction strengths) relative to seed abundance.</p> <p>This is made available as an R markdown file with associated data files.</p>
Data from: Quantitative genetic analysis of subspecific differences in body shape in the snail-feeding carabid beetle Damaster blaptoides
A dimorphic pattern of macrocephalic (wide, short) and stenocephalic (narrow, long) body shapes is observed in snail-feeding carabid beetles globally. The former exhibits high performance in crushing snail shells with powerful jaws, whereas the latter specializes in eating snails' soft body directly by inserting the head into the shell. In the snail-feeding species Damaster blaptoides, the subspecies D. b. capito has a wide short forebody, and D. b. fortunei has a narrow, long forebody. They exhibit distinct morphologies despite their geographic and phylogenetic proximity. To examine the genetic basis of the morphological differences between these two subspecies, we conducted quantitative genetic analyses by crossing these subspecies and producing F_1 and backcross hybrids. The hybrids had body shapes intermediate between the parental subspecies. The variation between wide, short and narrow, long forebodies was based on negative geneti c correlations between width and length of the head and thorax. Between one and eight genetic factors were involved in the morphological differences between subspecies. We suggest that the morphological integration of forebody parts in a small number of loci has facilitated the marked morphological diversification between subspecies of D. blaptoides.
Data from: The effect of plant identity and mixed feeding on the detection of seed DNA in regurgitates of carabid beetles
Carabids are abundant in temperate agroecosystems and play a pivotal role as biocontrol agents for weed seed and pest regulation. While there is good knowledge regarding their effects on invertebrate pests, direct evidence for seed predation in the field is missing. Molecular approaches are ideally suited to investigate these feeding interactions; however, the effects of an omnivorous diet, which is characteristic for many carabid species, and seed identity on the detection success of seed DNA has not yet been investigated. In a series of feeding experiments, seeds of six different Central European weed species were fed to beetles of the species Pseudoophonus rufipes, to determine post-feeding seed DNA detection rates and how these are affected by plant identity, meal size and chemical seed composition. Moreover, we investigated the effect of a mixed diet of seed and mealworm on prey DNA detection. Four out of six seed species were detectable for up to five days after consumption and seed species identity significantly affected post-feeding detection rates. Detectability was negatively influenced by protein content and seed mass, whereas oil content and meal size had a positive effect. The mixed diet led to both increased detection rates and post-feeding detection intervals of seed DNA. This suggests that mixed feeding leads to an enhancement of food detection intervals in carabid beetles and that seed identity, their chemical composition and meal size can affect DNA detection of consumed seeds. These aspects and potential implications of this non-invasive approach are discussed as they can become highly relevant for interpreting field derived data.
