Workshop: Phosphorus Cycling in Terrestrial Ecosystems: Advancing our fundamental understanding through an improved model-data connection; Spring, 2016; Moab, Utah

在广泛的生态系统中，磷(P)已被证明限制了许多基本的生态系统过程。然而，尽管它很重要，大多数地球系统模型目前都没有包括P周期的任何方面。这妨碍了这些模型在产生和检验假设以及预测全球变化影响方面的效用。重要的是，P建模工作面临的关键挑战也是整个科学界面临的关键挑战；也就是说，确定一条前进的道路，以提高我们对P周期的关键驱动因素、过程和全球变化响应的理解。汇集P专家将通过对P循环动力学的更综合的理解和概念化，整合各种P相关数据，改进基于过程的P循环建模以及P数据模型集成来解决这一需求。另一个潜在的进步源于研究P循环的经验主义者和考虑将P包含在一系列不同模型中的建模者之间明确合作的力量。该研讨会将包括所有职业阶段的科学家，包括学生和博士后，以及来自代表性不足群体的参与者。研讨会参与者将代表不同的理论、经验和数值模拟观点，这些观点对于提高我们对全球变化背景下陆地P循环的理解至关重要。会议将包括来自不同研究视角和方法的专家，预计将取得五项成果：1)通过各种评估提高对陆地磷循环的理解；2)可公开用于分析和建模的合成数据集；3)提交给同行评议期刊发表的会议报告和一套基于数据的补充论文；4)一套合作研究项目和资助计划，以确定获取关键领域所需知识的方法；5)一个致力于促进P研究跨学科方法的个人网络。

Phosphorus (P) has been shown to limit a number of fundamental ecosystem processes in a wide range of ecosystems. Despite its importance, however, most Earth system models do not currently include any aspect of the P cycle. This hinders the utility of these models for generating and testing hypotheses and for forecasting the effects of global change. Importantly, a critical challenge for P modeling efforts is also a critical challenge for the scientific community as a whole; namely, determining a way forward for improving our understanding of the key drivers, processes, and global change responses of the P cycle. Bringing together P experts will address this need through a more synthetic understanding and conceptualization of P cycle dynamics, integration of varied P-related data, improved process-based modeling of the P cycle, and P data-model integration. Another potential advance stems from the power of explicit collaborations between empiricists who study P cycling and modelers considering the inclusion of P in a range of different models. The workshop will include scientists at all career stages including students and postdocs, as well as participants from underrepresented groups. Workshop participants will represent diverse theoretical, empirical, and numerical modeling perspectives that are critical for improving our understanding of the terrestrial P cycle in the context of global change. The meeting will include experts that span a variety of research perspectives and methods and is expected to have five outcomes: 1) an improved understanding of terrestrial P cycling from varied assessments; 2) synthesized datasets that will be publicly available for analysis and modeling; 3) a meeting report that will be submitted for publication in a peer-reviewed journal and a complementary set of data-based papers; 4) a set of plans for collaborative research projects and grants to identify approaches to obtain the knowledge necessary for improved understanding in critical areas; and 5) a network of individuals dedicated to fostering cross-disciplinary approaches to P research.
