项目摘要

The objective of the proposed research is to develop a new approach to basic research in conservation biology--Species-Centered Environmental Analysis--and to apply it to an extensive study of the population dynamics of the endangered red-cockaded woodpecker in relation to its environment. The USDA Forest service has agreed to conduct an experimental 5-year prescribed-burning program in the longleaf pine forests of the Apalachicola National Forest in Florida in 60 management compartments where we will be able to monitor the birds and the ground cover vegetation. In a subset of 24 compartments, we will monitor the arthropod fauna of the pine trees and the movement of nutrients through the system. In 12 of the 24 compartments we will conduct a nutrient enrichment experiment in which treatments will include supplemental calcium with and without supplemental phosphorus and nitrogen. The major questions being asked are (1) Is the movement of nutrients through this ecosystem affected by the season and frequency of prescribed fire; and (2) Does this movement affect the nutritional quality of arboreal arthropods, the main diet of the woodpeckers. This project is an example of ecosystem management--the experimental application of management alternatives that allows the results of basic research in population and ecosystem ecology to be used to select among future management options.

本研究的目的是开发一种新的保护生物学基础研究方法——以物种为中心的环境分析方法，并将其应用于濒危红冠啄木鸟种群动态与环境的广泛研究。美国农业部林业局已经同意在佛罗里达州阿巴拉契科拉国家森林的长叶松林中进行一项为期5年的实验性处方燃烧项目，该项目分为60个管理区域，我们将能够在这些区域监测鸟类和地面植被。在24个隔间的一个子集中，我们将监测松树的节肢动物区系和营养物质在系统中的运动。在24个隔间中的12个隔间中，我们将进行营养富集实验，其中的处理包括补充钙和不补充磷和氮。主要的问题是：(1)营养物质在这个生态系统中的运动是否受到季节和规定火灾频率的影响；(2)这种运动是否会影响啄木鸟的主要食物——树栖节肢动物的营养质量。该项目是生态系统管理的一个例子——管理方案的实验性应用，允许使用人口和生态系统生态学的基础研究结果来选择未来的管理方案。
