title: Small skeletons show size-specific scaling: an exploration of allometry in the mammalian lumbar spine

description: Studies of vertebrate bone biomechanics often focus on skeletal
 adaptations at upper extremes of body mass, ignoring the importance of
 skeletal adaptations at lower extremes. Yet mammals are ancestrally small
 and most modern species have masses under 5 kg, so the evolution of
 morphology and function at small size should be prioritized for
 understanding how mammals make a living. We examined allometric scaling of
 lumbar vertebrae in the small-bodied Philippine endemic rodents known as
 cloud rats, which vary in mass across two orders of magnitude
 (15.5g-2700g). External vertebral dimensions scale with isometry or
 positive allometry, likely relating to body size and nuances in
 quadrupedal posture. In contrast to most mammalian trabecular bone
 studies, bone volume fraction and trabecular thickness scale with positive
 allometry and isometry, respectively. It is physiologically impossible for
 these trends to continue to the upper extremes of mammalian body size, and
 we demonstrate a fundamental difference in trabecular bone allometry
 between large- and small-bodied mammals. These findings have important
 implications for the biomechanical capabilities of mammalian bone at small
 body size, for the selective pressures that govern skeletal evolution in
 small mammals, and for the way we define “small” and “large” in the
 context of vertebrate skeletons.
description: Scans of murine vertebral columns (museum specimens sourced from
 the Field Museum of Natural History) were collected using a GE Phoenix
 v|tome|x µCT scanner. Spherical VOIs were chosen and segmented in ORS
 Dragonfly 2021. Trabecular bone morphological data were collected from
 medullary cavity VOIs using Dragonfly and BoneJ. See the publication
 Methods section for additional details.

In review. ## Data and File Overview ### Summary Metrics * File count: 5 * Total file size: 22.0 MB * Range of individual file sizes: 1.78 MB - 6.43 MB * File formats: .zip, with individual images within the file structure saved as 8-bit .tiffs. See the data structure below for details. ### Table of Contents * Batomys_tb_and_spacing_VOIs.zip * Carpomys_tb_and_spacing_VOIs.zip * Crateromys_tb_and_spacing_VOIs.zip * Musseromys_tb_and_spacing_VOIs.zip * Phloeomys_tb_and_spacing_VOIs.zip ### Setup * Recommended software/tools: ImageJ v.1.53t, BoneJ2 v.7.0.11 ## Data structure Each .zip file contains subfolders for each specimen of a single genus included in our analyses. Each specimen folder has two subfolders which contain two different versions of segmented vertebral trabecular bone images from the third lumbar vertebra of that specimen. Each version of the segmented data has a folder: trabecular bone segmentations are in folders ending in \_tball and non-bone/background segmentations are in folders ending in \_forspacing. For specific uses of these two versions of the data, see the associated manuscript, particularly Methods, Figure 2, and Supplemental Methods. All images are 8-bit .tiff. The structure of nested folders is shown below. ### Batomys\_tb\_and\_spacing\_VOIs.zip #### *Batomys granti* \|-- FMNH_188323_Batomys_granti_VOIs.zip # Zipped parent file for images from Field Museum of Natural History (FMNH) specimen no. 188323, *Batomys granti* \| |-- FMNH_188323_Batomys_granti_VOIs #
