Climate change and disruptions to global fire activity
Tập 3 Số 6 - Trang 1-22 - 2012
Future disruptions to fire activity will threaten ecosystems and human
well‐being throughout the world, yet there are few fire projections at global
scales and almost none from a broad range of global climate models (GCMs). Here
we integrate global fire datasets and environmental covariates to build spatial
statistical models of fire probability at a 0.5° resolution and examine
environmental contr...
A global perspective on wetland salinization: ecological consequences of a growing threat to freshwater wetlands
Tập 6 Số 10 - Trang 1-43 - 2015
Salinization, a widespread threat to the structure and ecological functioning of
inland and coastal wetlands, is currently occurring at an unprecedented rate and
geographic scale. The causes of salinization are diverse and include alterations
to freshwater flows, land‐clearance, irrigation, disposal of wastewater
effluent, sea level rise, storm surges, and applications of de‐icing salts.
Climate c...
Grasslands—more important for ecosystem services than you might think
Tập 10 Số 2 - 2019
AbstractExtensively managed grasslands are recognized globally for their high
biodiversity and their social and cultural values. However, their capacity to
deliver multiple ecosystem services (ES) as parts of agricultural systems is
surprisingly understudied compared to other production systems. We undertook a
comprehensive overview of ES provided by natural and semi‐natural grasslands,
using sout...
The fire frequency‐severity relationship and the legacy of fire suppression in California forests
Tập 6 Số 1 - Trang 1-23 - 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. Reference fire regimes in forested
ecosystems can be categorized along a gradient ranging from “fuel‐limited” to
“climate‐limited” where the former types are often characterized by frequent,
lower‐seve...
Wildfire‐mediated vegetation change in boreal forests of Alberta, Canada
Tập 9 Số 3 - 2018
AbstractClimate‐induced vegetation change may be delayed in the absence of
disturbance catalysts. However, increases in wildfire activity may accelerate
these transitions in many areas, including the western boreal region of Canada.
To better understand factors influencing decadal‐scale changes in upland boreal
forest vegetation, we developed a hybrid modeling approach that constrains
projections ...
Fungal community homogenization, shift in dominant trophic guild, and appearance of novel taxa with biotic invasion
Tập 8 Số 9 - 2017
AbstractInvasion by non‐native plants may fundamentally restructure the soil
fungal community. The invasive plant, Alliaria petiolata, produces secondary
compounds suppressive to mycorrhizal fungi and may therefore be expected to have
generally negative effects on other components of the fungal community. Here, we
compared fungal biomass, diversity, community composition, and the relative
abundanc...
Locally adapted arbuscular mycorrhizal fungi improve vigor and resistance to herbivory of native prairie plant species
Tập 6 Số 12 - Trang 1-16 - 2015
Soil microbial communities contribute to ecosystem function and structure plant
communities, but are altered by anthropogenic disturbance. Successful
restoration may require microbial community restoration. Inoculation of plants
with arbuscular mycorrhizal fungi (AMF) may improve ecological restoration, but
AMF species that are locally adapted to native plant communities are often
unavailable and ...
Plant preferential allocation and fungal reward decline with soil phosphorus: implications for mycorrhizal mutualism
Tập 7 Số 5 - 2016
AbstractExplaining the persistence of mutualism remains a challenge in ecology
and evolutionary biology. The evolutionary stability of arbuscular mycorrhiza, a
most widespread and ancient mutualistic association, is particularly intriguing
because plants lack apparent mechanisms to prevent cheaters from gaining
competitive advantages over cooperators. We developed a triple isotopic labeling
method...
Restoration of fire in managed forests: a model to prioritize landscapes and analyze tradeoffs
Tập 4 Số 2 - Trang 1-19 - 2013
Ongoing forest restoration on public lands in the western US is a concerted
effort to counter the growing incidence of uncharacteristic wildfire in
fire‐adapted ecosystems. Restoration projects cover 725,000 ha annually, and
include thinning and underburning to remove ladder and surface fuel, and seeding
of fire‐adapted native grasses and shrubs. The backlog of areas in need of
restoration combine...
Ecohydrology with unmanned aerial vehicles
Tập 5 Số 10 - Trang 1-14 - 2014
High‐resolution characterizations and predictions are a grand challenge for
ecohydrology. Recent advances in flight control, robotics and miniaturized
sensors using unmanned aerial vehicles (UAVs) provide an unprecedented
opportunity for characterizing, monitoring and modeling ecohydrologic systems at
high‐resolution (<1 m) over a range of scales. How can the ecologic and
hydrologic communities mo...
