SGER: Scales of Spatial and Temporal Patterns of Microbes Inhabiting Rodent Dens

本研究旨在确定两种沙漠啮齿动物（袋鼠鼠和木鼠）在Sevilleta LTER站点的洞穴中真菌的时空格局。众所周知，这些洞穴是真菌种群的聚集地，它们影响着群落动态和生态系统过程的许多方面，从啮齿动物的食物储存行为到木质材料的分解。将小管放置在洞穴中并用作采样端口，允许在洞穴内的同一位置重复采样。在六个相邻的核心洞穴内的六个地点，每年将进行四次采样，为期两年。与此同时，将在距离核心洞穴3.2公里处以几何方式增加采样，每个采样点为六个洞穴的两个样条。这些样品将被分析真菌的多样性、生长特性和生长兼容性。结果将揭示微生物动力学的重要方面，已知是生态重要的设置。

This study is designed to identify the spatial and temporal patterns of fungi in the dens of two species of desert rodents, (kangaroo rats and woodrats) at the Sevilleta LTER site. These dens are known to be foci of fungal populations, which influence many aspects of community dynamics and ecosystem processes, from food storage behavior of the rodents to decomposition of woody material. Small tubes will be placed in the dens and used as sampling ports, allowing repeated sampling from the same location within the dens. Six locations within six adjacent, core, dens will be sampled four times a year for two years. Concurrently, two transects of six dens each will be sampled at geometrically increasing distances up to 3.2 km from the core dens. The samples will be analyzed for fungal diversity, growth characteristics, and growth compatibility. The results will reveal important aspects of microbial dynamics in settings that are known to be ecologically important.
