“…Its permanent dentition thus comprises 44 teeth, this being the primitive number of the Eutheria (Thenius, 1989). Dental abnormalities, like absence of teeth, supernumerary teeth or teeth rotation have been recorded for wild and domestic pigs (Feldhammer & McCann, 2004). Sus scrofa generally exhibit more dental anomalies than other suids (Miles & Grigson, 1990).…”

“…Sex was established by the presence of large, rootless permanent mandibular tusk. The relative size of teeth (Albarella & Payne, 2005) and the presence of well-developed P 1 (missing antemortem) (Feldhammer & McCann, 2004) showed on mandible as belonging to a wild boar. …”

“…They usually result from the splitting of a bud or from local hyperactivity of the dental lamina (Garvey et al, 1999), although the topic is not resolved yet (Henderson & Greene, 1975). Studies of such anomalies in wild and domestic pigs have been carried out for quite a while (Gupta, 1978;Miles & Grigson, 1990;Feldhammer & McCann, 2004;Kierdorf et al, 2004b;Konjevic et al, 2006, and so on). However, most of the studies are focused on tusk abnormalities of modern animals (Kierdorf et al, 2000;Kierdorf and Kierdorf, 2003;,b,c, 2005Konjevic et al, 2004aKonjevic et al, ,b, 2006 with little or no information on archeological material (Magnell & Carter, 2007).…”

“…Among nonhuman primates, the highest frequencies of supernumerary teeth are concentrated within a single group (the hominoids), suggesting a phylogenetic (and thus a hered-itary) influence. Supernumerary teeth are generally less common in eutherian mammals retaining less derived dental formulae [Feldhamer and McCann, 2004;Gisburne and Feldhamer, 2005], for example pigs and wild canids ( table 3 ). Among primates, supernumerary teeth are most common in the large-bodied nonhuman hominoids (ranging from 2.9 to 7.9%; table 3 ), which have a more derived dental formula compared to most prosimians [Cuozzo and Yamashita, 2006].…”

“…Jablonski [1992] reported a 33.3% frequency of premolar agenesis in a sample of Rhinopithecus roxellana. Agenesis is also common among other mammals (gray foxes and wild pigs), with frequencies approaching or even exceeding 20% in some samples [Feldhamer and McCann, 2004;Gisburne and Feldhamer, 2005]. In modern humans, agenesis primarily occurs at the third molar position, with most examples of congenitally missing teeth across both the cercopithecoids and hominoids being molars [Lavelle and Moore, 1973].…”

While understanding somatic variability among wild primates can provide insight into natural patterns of developmental plasticity, published data for living populations are rare. Here we provide such information for two distinct wild populations of Lemur catta. Variants observed include microtia, athelia, and female virilization. Dental variants observed include individuals with supernumerary teeth, rotated teeth, maxillary incisor agenesis, and severe malocclusion. There was a sex bias in incisor agenesis, with 5 of 7 examples (71%) found in males. The frequency of dental variants in our sample is lower than that seen in many other lemuriformes, as well as other primates. This may be a product of their less derived dental formula and/or their relatively fast dental development. Amassing such data is a critical first step to assess if wild primate populations are exhibiting normal variability or are being affected by potential inbreeding and/or environmental effects.

Development and evaluation of a bait station for selectively dispensing bait to invasive wild pigs

et al. 2018

Populations of invasive wild pigs (Sus scrofa; hereafter, wild pigs) are expanding, requiring costeffective tools for control, and disease prevention, such as toxic or vaccine baits. Specifically, development of a novel and humane toxicant is underway for control of wild pigs in the United States and Australia. A speciesspecific bait station for delivering the toxic bait must be used to protect nontarget animals. Further, a bait station must be designed to maximize feeding by wild pigs by accommodating their group-feeding behaviors. We sought to develop a bait station that delivered bait to the maximum proportion of wild pigs and excluded the most ubiquitous nontarget species, specifically white-tailed deer (Odocoileus virginianus) and raccoons (Procyon lotor). We used direct observations and cameras during 2015 to evaluate wild pig feeding behavior and nontarget access for various sizes, arrangements, and construction materials of prototype bait stations in pen and field settings in Texas, USA. We found that a bait station constructed of 2 back-to-back troughs, 1.1 m in length, without a divider was sufficient for feeding the largest proportion of wild pigs in pens. Using this design of bait station at 30 field sites, we found that wild pigs fed more frequently from plastic than metal bait stations, although both bait stations reduced feeding by wild pigs compared with control sites. From near-video imagery at 3 field sites, we identified that 80% of wild pigs (33 of 41), 0% of white-tailed deer (0 of 7), and 17% of raccoons (1 of 6) accessed the bait stations on the final night of testing following a 2-week acclimation and training period. Future steps toward development of a wild pig-specific bait station include adding resistance to the lids of bait stations to completely exclude raccoons and identify baiting strategies that most efficiently acclimate wild pigs to using bait stations. Published 2018. This article is a U.S. Government work and is in the public domain in the USA.
