Beetles within this genus can live on all continents except Antarctica.
The parasite doesn't affect the harlequin but fatally overwhelms seven-spotted lady beetles within 2 weeks of infection, researchers report online today in Science.
Infested plots had at least 80% of the overstory ponderosa pine trees attacked by bark beetles within 2 years of our measurements.
To define retention targets for stump harvesting operations, we compared abundance and species richness of saproxylic beetles within individual stumps as well as species accumulation curves in replicated pairs of clear cuts with and without stump harvesting in northern Sweden.
The tribe Aciliini Thomson, 1867 belongs to the subfamily Dytiscinae, comprising most of the larger diving beetles within Dytiscidae.
These data provide evidence for functional redundancy of dung beetles within primary forest and emphasize the high value of logged forests as refugia for biodiversity.
These data provide evidence for functional redundancy of dung beetles within primary forest, as also suggested for birds in Amazonian forests (Hidasi-Neto, Barlow & Cianciaruso, 2012).
The two hybrid lines showed intermediate characteristics, relative to their parents, with the FemSW beetles starting oviposition approximately 3 weeks and the FemIT beetles within 4 weeks following emergence (Fig. 1).
In contrast, conversion of forest to oil palm greatly reduced taxonomic and functional diversity, with a marked decrease in the abundance of nocturnal foragers, a higher proportion of species with small body sizes and the complete loss of telecoprid species (dung-rollers), all indicating a decrease in the functional capacity of dung beetles within plantations.
The common eastern firefly, Photinus pyralis, is actually a beetle, and within the confines of New York City, may actually be more common now than a few dozen years ago.
