Graduate student Paul Kemp proposes to study the relationship between tissue and shell growth in gastropods, using a combination of shell morphometrics, computer modelling and controlled growth experiments. Based on his published undergraduate thesis, Kemp hypothesizes that variations in the growth rate of body tissue has a profound effect on the both the thickness and coiling geometry of the snail's shell. In that study, Kemp found striking shell differences within a species that differed principally in food supply. He proposes to raise populations at varying levels of food and calcium in the substrate. The project has broad implications not only for systematic practices among gastropod workers, but for the integration of biological and morphometric studies. Systematists will gain new insight into the direct effects of environemntal conditions on those characteristics often used to distinguish species. Paul Kemp is a quadriplegic. The proposal requests a specially modified microcomputer-based image analysis system. This award will support a valuable dissertation research project, allow Mr. Kemp to pursue a career in research, and aid in the design and development of research equipment for spine-injured scientists.

研究生保罗·肯普（Paul Kemp）打算利用贝壳形态测量学、计算机建模和受控生长实验相结合的方法，研究腹足类动物组织和贝壳生长之间的关系。根据他发表的本科论文，肯普假设身体组织生长速度的变化对蜗牛壳的厚度和盘绕几何形状都有深远的影响。在那项研究中，肯普发现了一个物种内部惊人的外壳差异，主要是食物供应的不同。他建议在不同的食物水平和基质中钙含量的情况下提高种群数量。该项目不仅对腹足动物工作者的系统实践有广泛的影响，而且对生物学和形态计量学研究的整合也有广泛的影响。系统学家将获得新的见解，了解环境条件对那些经常用来区分物种的特征的直接影响。保罗·肯普四肢瘫痪。该提案要求一个特别改进的基于微机的图像分析系统。该奖项将支持一项有价值的论文研究项目，允许Kemp先生从事研究事业，并帮助脊椎受伤的科学家设计和开发研究设备。
