The most dramatic biological pattern on Earth, the gradient of increasing diversity of species and major groups from the poles to the tropics, is well-documented but the processes generating and maintaining this pattern remains poorly understood. Understanding the factors behind the latitudinal diversity gradient is crucial for developing a more rigorous picture of the dynamics of biodiversity, and for better management of marine biodiversity informed by history to predict species' responses to future global changes. To investigate those processes, this research will inventory the past and present spatial distributions of species in an ecologically and economically important group, the marine bivalves, an ideal target because their excellent fossil record can track the origin, spread, and range-contraction of lineages in response to past episodes of global change. Factors potentially shaping the present-day diversity gradient, such as the rate of environmental change and features of the species themselves, such as food source and body size, will be evaluated by synthesizing museum collections and published records. The work will contribute a large block of data to the public Paleobiology Database, support training of undergraduates and a postdoctoral scholar, and produce on-line educational resources, including a high-school teaching module derived from the research.

地球上最引人注目的生物模式是物种和主要群体从两极到热带的多样性逐渐增加的梯度，这是有据可查的，但对产生和维持这种模式的过程仍然知之甚少。了解纬度多样性梯度背后的因素，对于更准确地描绘生物多样性的动态，更好地管理以历史为依据的海洋生物多样性，以预测物种对未来全球变化的反应，至关重要。为了研究这些过程，本研究将清点过去和现在的空间分布的物种在生态和经济上的重要群体，海洋双壳类，一个理想的目标，因为他们优秀的化石记录可以跟踪起源，传播和范围收缩的谱系，以应对过去的全球变化。将通过综合博物馆收藏品和出版记录，评估可能形成当今多样性梯度的因素，如环境变化的速度和物种本身的特征，如食物来源和体型。这项工作将为公共古生物学数据库提供大量数据，支持本科生和博士后学者的培训，并制作在线教育资源，包括从研究中派生的高中教学模块。
