“…Only a few efforts have been completed. De la Rosa et al (2012) found evidence of differentiation between the Texanus, Carminis, Veracrusis, Yucatanensis, and Sinaloe WTD subspecies, and Ambriz (2012) found specific variations in genes at mitochondrial level among those subspecies. These findings might suggest the specific genetic or lineage background and necessity for protecting their own genetic diversity; the same assumptions can be made in regions without a geographic barrier and with the same agro-climatic condition, but analyses remain to be done.…”

The white-tailed deer (Odocoileus virginianus) is one of the most important species related to sport hunting in northern Mexico. During the last decade, this species has been subjected to intensive breeding to achieve improvements in certain desired traits (i.e., antlers). This alleged intensive management of bringing originally wild populations into captivity might have harmful consequences on genetic diversity. In this short research paper we estimate and discuss the consequences of that transition, as assessed by a microsatellite genetic marker analysis. The results show that no short-term changes in genetic diversity parameters were promoted by captivity; however, a genetic diversity condition maintained by artificial genetic flow was identified, perhaps allowing for the required introgression of gene diversity into this closed population. A wider analysis is recommended and the implications are discussed. Within a realistic forecast of expanding sport hunting, the achievement of useful, pragmatic, and strict conservancy programs of this species, considering approaches such as those used here, will be necessary.

“…In other populations of O. virginianus, Hernández (2010), in his work on space-time dynam-ics of O. virginianus, compared different populations belonging to UMA, obtaining low heterozygosity values (H o = 0.60, H e = 0.82). In another study, De la Rosa-Reyna et al (2012) when evaluating subspecies of O. virginianus from different geographic regions of Mexico, found that heterozygosity was different between subspecies and the H o was less than H e (H o = 0.59, H e = 0.76; H o = 0.53, H e = 0.85; H o = 0.64, H e = 0.78). Kollars et al (2004) report a low H o (0.19 -0.22) for five populations of O. virginianus in the state of Tennessee, USA.…”

“…Blood samples were stored in refrigeration at 15 °C (Serna-Lagunes et al 2012) and the DNA was extracted with PROMEGA E. Z. N. A. Tissue DNA KIT, following the Blood and Body Fluids protocol. To characterize the genetic diversity of the population of deer, six microsatellite markers were genotyped: BM203, BM4208, D, BM848, TGLA126 and MSTN01, which were initially described for genetic exclusion studies (DeYoung et al 2003a) and have been tested in O. v. veraecrucis and other subspecies (De la Rosa-Reyna et al 2012).…”

“…The PCR amplification program included the following stages: initial denaturation at 95 for 2 min, denaturation at 95 °C at 1 min, alignment at 54 °C for 30 s, extension at 72 °C for 1 min; final extension at 72 °C for 5 min, and at 4 °C until samples are withdrawn. These conditions were adapted based on those reported by De la Rosa-Reyna et al (2012). The amplified PCR products were verified on 1.5% agarose gels; those microsatellites that did not amplify on a first occasion or where the amplification was not clear were subjected to PCR again until a reliable amplification was obtained.…”

The genetic diversity and effective population size (Ne) of a population of Odocoileus virginianus veraecrucis in captivity were characterized in the Wildlife Management Unit “El Pochote”, located in Ixtaczoquitlán, Veracruz, Mexico. Blood tissue was collected from 20 individuals of the reproductive nucleus, its genomic DNA was extracted, and genetic diversity was characterized by six microsatellites amplified by PCR and visualized in polyacrylamide gels. With four polymorphic microsatellites, 66.7% of the population’s genetic variation was explained, which was characterized by an allelic diversity that fluctuated between 9 and 28 alleles (18 average alleles), suggesting a mean allelic diversity (Shannon index = 2.6 ± 0.25), but only 12 ± 2.9 effective alleles would be fixed in the next generation. The heterozygosity observed (Ho= 0.81) exceeded that expected (He= 0.79) and these were significantly different (P> 0.05), as a result of a low genetic structure in the population (fixation index F = -0.112 ± 0.03), due to the genetic heterogeneity that each sample contributed, since the specimens came from different geographical regions. The Ne was 625 individuals and a 1:25 male:female ratio, with which 100% of the genetic diversity observed can be maintained for 100 years. The information obtained in the study can help in the design of a reproductive management program to maintain the present genetic diversity, without risk of losses due to genetic drift and inbreeding.

“…Overall, genetic diversity in the confined deer population is comparable to white-tailed deer populations in other parts of their range. This includes populations with no history of population size reductions [45,[49][50][51] and populations that have undergone bottlenecks or founder events (e.g., through translocation or introductions) [31,52]. Genetic diversity of deer within our study population is considerably higher than in populations with known long-term isolation and small population sizes, such as Key deer (O. v. clavium) [53] and Columbian white-tailed deer (O. v. leucurus) [54].…”

Fencing wildlife populations can aid wildlife management goals, but potential benefits may not always outweigh costs of confinement. Population isolation can erode genetic diversity and lead to the accumulation of inbreeding, reducing viability and limiting adaptive potential. We used microsatellite and mitochondrial DNA data collected from 640 white-tailed deer confined within a 1184 ha fence to quantify changes in genetic diversity and inbreeding over the first 12 years of confinement. Genetic diversity was sustained over the course of the study, remaining comparable to unconfined white-tailed deer populations. Uneroded genetic diversity suggests that genetic drift is mitigated by a low level of gene flow, which supports field observations that the fence is not completely impermeable. In year 9 of the study, we observed an unexpected influx of mtDNA diversity and drop in inbreeding as measured by FIS. A male harvest restriction imposed that year increased male survival, and more diverse mating may have contributed to the inbreeding reduction and temporary genetic diversity boost we observed. These data add to our understanding of the long-term impacts of fences on wildlife, but also highlight the importance of continued monitoring of confined populations.
