Most biodiversity research programs now use biomolecules (DNA and RNA) to help identify, determine evolutionary relationships, or study population biology of species. To meet this need, the North Carolina Museum of Natural Sciences, the largest natural history museum in the Southeast U.S., routinely preserves biomolecules in the form of tissue samples taken from voucher specimens. The collection contains tissues from many species of vertebrates and aquatic invertebrates, including rare and not easily replaced species, and the number of tissue loans made by the museum to external scientific researchers is beginning to outpace that of traditional museum specimens. This important genetic resources collection has been at risk because ultra-cold facilities are not available at the museum to prevent biomolecules from degrading over time at warmer storage temperatures. This project addresses this shortcoming by providing two ultra-cold freezers, associated tissue storage supplies, and technician time to transfer the collection into ultra-cold storage and update the online collections database.Ensuring the long-term preservation of this collection will greatly improve its utility to a wide variety of user groups in the scientific and resource management communities, especially those in the fields of systematics, population genetics, and conservation genetics. Such research will facilitate informed decisions by conservation planners mitigating loss of biodiversity. The positive scientific impacts of this project will be shared with the U.S. public through three exhibits on biodiversity research at the museum, which is free-of-charge and potentially reaching over 800,000 visitors annually.

现在，大多数生物多样性研究计划现在都使用生物分子（DNA和RNA）来帮助识别，确定物种的进化关系或研究种群生物学。为了满足这一需求，北卡罗来纳州自然科学博物馆是美国东南部最大的自然历史博物馆，通常以从优惠券标本采集的组织样本形式保存生物分子。该系列包含来自许多脊椎动物和水生无脊椎动物的组织，包括稀有和不容易替代的物种，博物馆向外部科学研究人员提供的组织贷款数量开始超过传统博物馆标本的空间。这项重要的遗传资源收集处于危险之中，因为博物馆无法使用超冷的设施来防止生物分子在较高的储存温度下随着时间的推移降解。该项目通过提供两个超冷的冷冻机，相关的组织存储供应以及技术人员的时间来解决这一缺点，以将其转移到超冷的存储中并更新在线收藏数据库。避免对该系列的长期保存将大大改善其实用性，将其实用性改善其对科学和资源管理社区中各种各样的用户群体的实用性，尤其是这些领域的系统，尤其是SystoneSics of Systomats of Systomats of Systomats of Synecsics of Synectsics of Synect，基因基因，以及基因的基因，以及基因的基因，以及基因的基因研究。这样的研究将通过保护计划者来促进明智的决定，从而减轻生物多样性的丧失。该项目的积极科学影响将通过博物馆的三个生物多样性研究展览与美国公众分享，该展览是免费的，该展览是免费的，每年有可能吸引80万多名访客。
