Data from: Undocumented beetle diversity in the Southeastern United States: a case study of the minute clubbed beetles (Coleoptera: Monotomidae)
Studies of the saproxylic and predatory beetle family Monotomidae (Coleoptera: Cucujoidea) in the southeastern USA increased the known diversity for the family in the state of Georgia by one genus and nine species. Online records of Monotomidae from Georgia increased from 0 to 885. This work highlights the lack of basic diversity information about small beetles that inhabit wood, leaf litter, and other decaying plant matter in this region.

XFP-056-16 Whale bone club, Sanak Island, Alaska
Whale bone club, Sanak Island, Alaska. CAT# XFP-056-16 XFP-056 is a group of large house depressions on the south shore of Pauloff Harbor, Sanak Island, Alaska. Multiple radiocarbon dates place it from 300 CE to 800 CE, although the upper most levels may date to the 13th century. These artifacts were scanned with either a Faro Edge Arm or a Minolta Vivid 9i. Processed in Geomagic or Polyworks. 4-8 photos were used for texture in ZBrush. The Sanak Island artifacts are presented as a result of the research conducted under grants NSF 0326584, NSF 0508101, NSF 1139266, NSF 1321411. H. Maschner, Principal Investigator. Original digitizing work done at the IVL at Id. St. Univ. Subsequent processing completed at Global Digital Heritage.

Epidermal club cell densities in fathead minnows: assessment of method and application to a case study
<p><strong>Abstract</strong></p> <p>Many fishes possess epidermal club cells that are the presumptive source of chemical alarm cues and also play a role in innate immune defense. Club cell density has been estimated in some studies but a standardized method for quantifying these cells is lacking.</p> <p>Here, we assess the repeatability of estimating club cell density in fathead minnows (<em>Pimephales promelas</em>). Thin-sectioned histological samples of fathead minnows were stained and mounted on slides and then digitally scanned for scoring. We estimated epidermal area using the segment tool in ImageJ to simulate the traditional method of scoring microscope slides using an ocular micrometer, where epidermal area was estimated by the lengths of straight-line segments of epidermal thickness and length of the tissue sample. The second approach measured epidermal area using the freehand tool in ImageJ.</p> <p>The R<sup>2</sup> value for repeated estimates of club cell density (club cells/mm<sup>2</sup>) ranged from 0.959 and 0.969, depending on the method used to estimate epidermal area. Measurement error in estimates of epidermal area was greater than measurement error in cell counts and the freehand tool was more repeatable than the segment tool as a method to measure epidermal area.</p> <p>We applied these methods to test differences in club cell densities between two sources of fathead minnows; wild-caught fish versus lab-reared fish provided by the Environmental Protection Agency. Lab-reared fish had higher densities of club cells than wild-caught fish did, likely reflecting differences in body condition.epidermal club cells</p>

FIGURE 2. Kalanchoe luciae, plants of which are the largest-growing of the species included in K. sect.
