The ecology and significance of below-ground bud banks in plants

Publications Posted on: July 10, 2019
Background: Below-ground bud banks have experienced much recent interest due to discoveries that they (1) account for the majority of seasonal population renewal in many communities, (2) are crucial to regeneration following disturbance, and (3) have important consequences for plant population dynamics and plant and ecosystem function across a number of habitats.

Integrating Sunda clouded leopard (Neofelis diardi) conservation into development and restoration planning in Sabah (Borneo)

Publications Posted on: May 16, 2019
Changes in land use/cover are the main drivers of global biodiversity loss, and thus tools to evaluate effects of landscape change on biodiversity are crucial.

Sprawling and diverse: The changing U.S. population and implications for public lands in the 21st Century

Publications Posted on: June 29, 2018
Public lands are typically established in recognition of their unique ecological value, yet both ecological and social values of public lands change over time, along with human distribution and land use. These transformations are evident even in developed countries with long histories of public land management, such as the United States.

Tree demography records and last recorded fire dates from the Pinaleño Demography Project, Arizona USA

Datasets Posted on: March 15, 2018
This data publication includes tree measurements taken from 2008-2013 across a gradient of forest types in the Pinaleño Mountains in southeastern Arizona, USA. Tree data include: species, pith date, and last recorded fire date. These data were collected as part of the USDA Forest Service, Rocky Mountain Research Station (RMRS) Growth and Demography of Pinaleño High Elevation Forests research project.

Forests transformed by fire exclusion help us understand climate resilience

Science Spotlights Posted on: November 06, 2017
The onset of fire exclusion in western North American forests in the late 1800s began one of the largest unintended landscape ecology experiments in human history. The current ecology of these forests and the ecological impacts of returning fire to these forests is strongly influenced by the amount of forest change that has occurred during the fire-free period. Understanding how different forest types responded to fire exclusion is important for implementing management strategies that restore fire as a natural process, promote forest health, and maintain well-functioning forests for future generations.  

Disturbance and productivity interactions mediate stability of forest composition and structure

Publications Posted on: April 14, 2017
Fire is returning to many conifer-dominated forests where species composition and structure have been altered by fire exclusion. Ecological effects of these fires are influenced strongly by the degree of forest change during the fire-free period. Response of fire-adapted species assemblages to extended fire-free intervals is highly variable, even in communities with similar historical fire regimes.

Applications of landscape genetics to connectivity research in terrestrial animals [Chapter 12]

Publications Posted on: August 18, 2016
Landscape genetic studies have focused on terrestrial animals more than any other taxonomic group. This chapter focuses on applications of landscape genetics for understanding connectivity of terrestrial animal populations. It starts with a general introduction covering unique characteristics and challenges of the terrestrial study system.

A dynamical model for bark beetle outbreaks

Publications Posted on: August 17, 2016
Tree-killing bark beetles are major disturbance agents affecting coniferous forest ecosystems. The role of environmental conditions on driving beetle outbreaks is becoming increasingly important as global climatic change alters environmental factors, such as drought stress, that, in turn, govern tree resistance.

The Northern Goshawk: Ecology and management: Proceedings of a symposium of the Cooper Ornithological Society

Publications Posted on: May 12, 2016
This collection of 22 papers summarizes the current state of knowledge on Northern Goshawks (Accipiter gentilis) within the scientific and management communities. The proceedings are presented in three sections. Research Approaches and Management Concepts contains overviews of research and management for goshawks, forest management to provide goshawk habitat, and field techniques.
