Fire regimes shape biodiversity: responses of avian guilds to burned forests in Andean temperate ecosystems of southern Chile

open access: yesAvian Conservation and Ecology, 2021
Fire regimes of forests, i.e., time interval, frequency, extent, and severity of fire events, influence structural changes in the vegetation, and thus shape the composition of avian communities.

“Fire and Society in Modern China: Fire Disasters and Natural Landscapes in East Asian Environmental History” (1820-1965)

open access: yesThe ASIANetwork Exchange: A Journal for Asian Studies in the Liberal Arts, 2012
Land clearance and agriculture have long been associated with fire.  Open fire, whether from natural or human ignition, has changed the face of many natural landscapes, especially in frontier regions.

Fire history and tree population dynamics in Białowieża Forest, Poland and Belarus [PDF]

open access: yes, 2016
Fire history and fire regime parameters in relation to the long-term tree population dynamics were studied with dendroecological methods across coniferous habitats of Białowieża Forest (E Poland and W Belarus), a semi-natural European temperate woodland ...

Multiobjective Codesign Optimization of a Planar Pneumatic Artificial Muscle‐Based Snake‐Like Robot for Enhanced Agility and Energy Efficiency

open access: yesAdvanced Robotics Research, EarlyView.
A codesign multiobjective optimization framework was developed to enhance the morphology and controller of a snake‐like robot driven by artificial muscles. It improved planar locomotion, agility, and power efficiency. The approach optimized link geometry and controller gains, revealing that shorter muscles near joints and longer linkages maximize ...

Fire and climate in Mongolia (1532–2010 Common Era)

open access: yesGeophysical Research Letters, 2016
Recent increases in wildland fire, warming temperatures, and land use change have coincided in many forested regions, making it difficult to parse causes of elevated fire activity. Here we use 20 multicentury fire scar chronologies (464 fire scar samples)

Significant Tropospheric O3 Production from Extratropical Forest Fires:When? When Not? [PDF]

open access: yes
There is significant controversy on whether extratropical fires contribute importantly to widespread ozone productionabsent the addition of urban pollutant nitrogen oxides (Jaffe and Widger, 2012, Singh et al., 2012,2013). Wereport a significant range of

Cell Cycle Control of Nuclear Metabolism Couples Phosphatidylinositol Signaling to Histone Methylation

open access: yesAdvanced Science, EarlyView.
Nuclear metabolism oscillates during cell cycle progression. Quantitative chromatome proteomics and imaging reveal phase‐specific dynamics of PIP5K1A and nuclear PIP2, linking phosphatidylinositol metabolism to histone methylation. This work identifies nuclear lipid metabolism as a previously unrecognized regulatory axis coordinating chromatin ...

Innovations spread more like wildfires than like infections [PDF]

open access: yes
Conventional theory says that innovations first diffuse slowly, then at faster paces, and finally at asymptotically declining rates. Economists and others explain such behavior with a variety of logistic models.
