Interactions between large high-severity fires and salvage logging on a short return interval reduce the regrowth of fire-prone serotinous forests [PDF]

Forest Ecology and Management, 2018
Abstract New fire disturbance regimes under accelerating global environmental change can have unprecedented consequences for ecosystem resilience, lessening ecosystem natural regeneration. In the Mediterranean Basin, fire-dependent obligate seeder forests that are prone to increasingly frequent stand-replacing fires and then salvaged logged ...

Distribution and frequency of wildfire in California riparian ecosystems

Environmental Research Letters, 2017
Although wildfire has been recognized as having important ecological impacts on California’s riparian environments, understanding of its occurrence is largely anecdotal, based on studies of fire impacts in scattered locations.

Management and climate variability effects on understory productivity of forest and savanna ecosystems in Oklahoma, USA

Ecosphere, 2021
The productivity of herbaceous and understory woody vegetation is critical for wildlife habitat, livestock forage, and biodiversity, and is influenced by both annual weather patterns and tree dominance.

Climate change, fire return intervals and the growing risk of permanent forest loss in boreal Eurasia

, 2021
Climate change has driven an increase in the frequency and severity of fires in Eurasian boreal forests. A growing number of field studies have linked the change in fire regime to post-fire recruitment failure and permanent forest loss. In this study we used four burnt area and two forest loss datasets to calculate the landscape-scale fire return ...

The fire frequency‐severity relationship and the legacy of fire suppression in California forests

Ecosphere, 2015
Fire is one of the most important natural disturbance processes in the western United States and ecosystems differ markedly with respect to their ecological and evolutionary relationships with fire.

Impacts of prescribed burning on Sphagnum mosses in a long-term peatland field experiment. [PDF]

PLoS ONE, 2018
Understanding fire impacts on peatland vegetation can inform management to support function and prevent degradation of these important ecosystems. However, time since burn, interval between burns and number of past burns all have the potential to modify ...

Effects of overstory structure and fire regime upon diversity and abundance of selected understory species in longleaf pine (Pinus palustris Mill.) forests in southeastern Georgia

Journal of Forest Science, 2003
We examined the impacts of variation in overstory structure and burning regime on understory vegetation in the longleaf pine (Pinus palustris Mill.) forest of the Okefenokee National Wildlife Refuge in southeastern Georgia, U.S.A.

A Holocene fire history from Terra Nova National Park, Newfoundland, Canada: vegetation and climate change both influenced the fire regime

Frontiers in Ecology and Evolution
Fire is the largest natural disturbance factor in the boreal forest and plays a critical role in the composition, structure, and succession of stands and landscapes.

Vegetation response to a short interval between high-severity wildfires in a mixed-evergreen forest [PDF]

, 2009
1 Variations in disturbance regime strongly influence ecosystem structure and function. A prominent form of such variation is when multiple high-severity wildfires occur in rapid succession (i.e. short-interval (SI) severe fires, or ‘re-burns’).

Entropy‐Driven Design of Low‐Melting‐Point Alloys via Compositionally Complex Strategy

Advanced Engineering Materials, EarlyView.
Conventional low‐melting‐point alloys (LMPAs) are limited by a narrow compositional space and inherent property trade‐offs. This review presents an entropy‐driven design strategy that overcomes these limitations, ushering in a new class of low‐melting‐point compositionally complex alloys (LMCCAs).
