Forest disturbance by an ecosystem engineer: beaver in boreal forest landscapes [PDF]

, 2013
Natural disturbances are important for forest ecosystem dynamics and maintenance of biodiversity. In the boreal forest, large-scale disturbances such as wildfires and windstorms have been emphasized, while disturbance agents acting at smaller scales have

How BFAST Trend and Seasonal Model Components Affect Disturbance Detection in Tropical Dry Forest and Temperate Forest

, 2021
Time series analysis has gained popularity in forest disturbance monitoring thanks to the availability of satellite and airborne remote sensing images and the development of different time series methods for change detection.

Daily Maximum Temperatures Induce Lagged Effects on Leaf Unfolding in Temperate Woody Species Across Large Elevational Gradients

Frontiers in Plant Science, 2019
The timing of leaf unfolding in temperate woody species is predominantly controlled by the seasonal course of temperature in late winter and early spring. However, quantifying lagged temperature effects on spring phenology is still challenging.

Monitoring disturbance intervals in forests: a case study of increasing forest disturbance in Minnesota [PDF]

Annals of Forest Science, 2019
We develop analytical methods and explore trends in disturbance interval via systematic forest inventory observations at a bioregional scale.ContextOur study spans the dynamic ecotone at the intersection of southern boreal forest, mixed hardwood forest, and tall-grass prairie ecosystems in Minnesota, USA.

Forest Age Mapping Using Landsat Time-Series Stacks Data Based on Forest Disturbance and Empirical Relationships between Age and Height

, 2023
Forest age is a critical parameter for the status and potential of carbon sequestration in forest ecosystems and reflects major forest disturbance information. However, reliable forest age data with high spatial resolution are lacking to date.

Interaction Diversity Maintains Resiliency in a Frequently Disturbed Ecosystem

Frontiers in Ecology and Evolution, 2019
Frequently disturbed ecosystems are characterized by resilience to ecological disturbances. Longleaf pine ecosystems are not only resilient to frequent fire disturbance, but this feature sustains biodiversity.

A novel approach to fuel biomass sampling for 3D fuel characterization

MethodsX, 2018
Surface fuels are the critical link between structure and function in frequently burned pine ecosystems, which are found globally (Williamson and Black, 1981; Rebertus et al., 1989; Glitzenstein et al., 1995) [1–3].

Circular RNA expression landscapes in myelodysplastic neoplasms: Associations with mutational signatures and disease progression

Molecular Oncology, EarlyView.
In this explorative study, the abundance of circular RNA molecules in bone marrow stem cells was found to be elevated in patients with high‐risk myelodysplastic neoplasms, and to be associated with an increased risk of progression to acute myeloid leukemia.

The Rapid Initial Community Builder (RICB) V1.1 for LANDIS-II

MethodsX
Forest succession, or ecosystem process models, can aid in many land management decisions as they inherently incorporate ecological processes to predict how disturbances impact the resilience of the forest and its potential future structure.
