Female mortality and low fertilization rate, and genital lock‐and‐key appears to exert significant selection against hybridization in the hybrid zone of these carabid beetles.
Evolutionary Relationships Among Food Habit, Loss of Flight, and Reproductive Traits: Life-History Evolution in the Silphinae (Coleoptera: Silphidae)
It was found that total egg production increased with flight loss and egg size increased with decreased egg number following food habit changes in the lineage leading to predaceous species, suggesting that selection for larger larvae intensified with the food habit change.
Diverse diet compositions among harpaline ground beetle species revealed by mixing model analyses of stable isotope ratios
The objective was to determine variation in diet composition among harpaline ground beetle species occurring in a riverside grassland.
Flight capabilities and feeding habits of silphine beetles: are flightless species really “carrion beetles”?
The flight capabilities and feeding habits of adults of nine silphine beetle species are determined and some have isotopic ratios close to those of the nicrophorine species, suggesting that these species mainly feed on vertebrate carcasses.
Discovery of mycangia and the associated xylose-fermenting yeasts in stag beetles (Coleoptera: Lucanidae)
The discovery of the microbe-storage organ (mycangium) in stag beetles (Coleoptera: Lucanidae), which develop in decayed wood, is reported here.
Species status and phylogeography of two closely related Coptolabrus species (Coleoptera: Carabidae) in South Korea inferred from mitochondrial and nuclear gene sequences
Investigating the species status and intraspecific phylogeography in South Korea of two ground beetle species found that although these two species represent a notable case of trans‐species polymorphisms in both mitochondrial and nuclear gene sequences, their status as separate species was evidenced by the nonrandom association between species and nested clades at various nesting levels.
Mechanical barriers to introgressive hybridization revealed by mitochondrial introgression patterns in Ohomopterus ground beetle assemblages
Mechanical isolation mechanisms reduce the chance of introgressive hybridization between closely related species through mechanical isolation, highlighting the role of morphological divergence in speciation and assemblage formation processes through mechanical isolate.
Different phylogeographic patterns in two Japanese Silpha species (Coleoptera: Silphidae) affected by climatic gradients and topography
This study demonstrates that, even between closely related species, interactions among biology, latitudinal climatic gradients and topography can produce different phylogeographic patterns.
Niche differentiation of burying beetles (Coleoptera: Silphidae: Nicrophorinae) in carcass use in relation to body size: Estimation from stable isotope analysis
The largest and smallest Nicrophorus species in Japan showed the highest δ15N and the smallest showed the lowest δ13C and δ 15N among all NicroPHorus species, suggesting that their niches are differentiated from those of other species in carcass resource.
