Data from: Trunk dental tissue evolved independently from underlying dermal bony plates but is associated to surface bones in living odontode-bearing catfish
Although oral dental tissue is a vertebrate attribute, trunk dental tissue evolved in several extinct vertebrate lineages but is rare among living species. The question of which processes trigger dental-tissue formation in the trunk remains open, and would shed light on odontogenesis evolution. Extra-oral dental structures (odontodes) in the trunk are associated with underlying dermal bony plates, leading us to ask whether the formation of trunk bony plates is necessary for trunk odontodes to emerge. To address this question, we focus on Loricarioidei: an extant, highly diverse group of catfish whose species all have odontodes. We examined the location and cover of odontodes and trunk dermal bony plates for all six loricarioid families and 17 non-loricarioid catfish families for comparison. We inferred the phylogeny of Loricarioidei using a new 10-gene dataset, eight time-calibration points, and noise-reduction techniques. Based on this phylogeny, we reconstructed the ancestral states of odontode and bony plate cover, and find that trunk odontodes emerged before dermal bony plates in Loricarioidei. Yet we discovered that when bony plates are absent, other surface bones are always associated with odontodes, suggesting a link between osteogenic and odontogenic developmental pathways, and indicating a remarkable trunk odontogenic potential in Loricarioidei.
Data from: Primary dermal fibroblasts and pectoralis muscle show similar patterns of oxidative stress in tropical and temperate birds despite differing life-histories
<p><span>Tropical birds have a "slower pace of life," with lower rates of whole-animal metabolism, smaller metabolically active organs, and lower cellular metabolic rates than their temperate counterparts. Oxidative stress is a physiological mechanism that may dictate differing life-histories such as those found between tropical and temperate birds. <span>Oxygen is required to make ATP, resulting in the production of reactive oxygen species (ROS)</span>. If left unchecked, ROS can structurally alter proteins, induce mutations in DNA, and damage structural lipids. To combat accumulating oxidative damage, organisms have evolved an elaborate and costly antioxidant system that serves to sequester ROS before they wreak cellular havoc. We examined whether oxidative stress would differ between tropical and temperate birds. We used isolated primary dermal fibroblasts and pectoralis muscle tissue for measurements. We measured four aspects of oxidative stress in primary fibroblasts – reduced glutathione (GSH) concentration, ROS production, mitochondrial content, and lipid peroxidation (LPO) damage. We found no significant differences in the four variables between temperate and tropical birds.. In muscle tissue, we measured catalase (CAT), superoxide dismutase (SOD) glutathione peroxidase (GPx) activity, peroxyl and hydroxyl scavenging capacity, and LPO damage. We found that peroxyl scavenging capacity was significantly higher in tropical birds compared with temperate birds. </span></p>
FIGURES 29–32 in Metaperipatus inae sp. nov. (Onychophora: Peripatopsidae) from Chile with a novel ovarian type and dermal insemination
FIGURES 29–32. Spermatophores from body surface of different females in Metaperipatus inae sp. nov.. 29, Light micrograph of a spermatophore (arrow) attached to the ventral body surface. 30, SEM micrograph of a spermatophore (sp) from the dorsal body surface. 31–32, TEM micrographs of a sectioned spermatophore containing sperm (sz). 31, Overview. Note the close association of the spermatophore with the female's body surface. The arrow points to the region where the envelope is lacking and the lumen of the spermatophore directly borders the female's cuticle. 32, Detail of spermatophore envelope (en) closely associated with the female's cuticle (cu). Within the envelope, irregularly-shaped inclusions (in) are found. Br = sensory bristle, cu = cuticle, dp = dermal papilla, en = envelope of spermatophore, ep = epidermis, ex = exterior, in = irregular inclusions, le = walking legs (numbered), lu = lumen of spermatophore, nu = nuclei of epidermal cells, sp = spermatophore, sz = sperm cells, vm = ventral midline, vp = ventral pits (usually termed "ventral organs").

In both species, there are four spinous footpads (numbered). The fourth pad is narrow, fragmented (and hardly recognized by light microscopy). The nephridial tubercle (ne) is placed in the middle of the third footpad. 15–16, Feet of adult specimens showing paired claws (cl) and distal foot papillae (arrows) that are duplicated in most cases. Circular insets represent feet in one day (M. inae sp. nov.), and two days old juveniles (M. blainvillei), respectively. Note that in juveniles, there are 3–4 distal papillae that are not duplicated or triplicated yet. Cl = claws, ft = foot, ne = nephridial tubercle.
