Forest productivity mitigates human disturbance effects on late-seral prey exposed to apparent competitors and predators

Scientific Reports, 2017
Primary production can determine the outcome of management actions on ecosystem properties, thereby defining sustainable management. Yet human agencies commonly overlook spatio-temporal variations in productivity by recommending fixed resource extraction

The causal effect of agricultural landscape simplification on Germany's grasslands during a compound drought and heatwave in 2018

American Journal of Agricultural Economics, EarlyView.
Abstract Preserving ecosystem services, along with economic and environmental benefits, will require future landscape policies to identify and incorporate relevant landscape features. In this paper, we investigate the causal effect of agricultural landscape simplification on drought‐related grassland damages.

Income sharing for common pool resources with uncertain productivity

American Journal of Agricultural Economics, EarlyView.
Abstract We address the interconnected issues of externalities in the use of a natural common‐pool resource system and adverse effects of environmental uncertainty on risk‐averse resource users. We set up a simple analytical model and derive conditions such that insurance by means of an income sharing mechanism mitigates externalities and hence ...

The relationships between ecosystem CO₂ fluxes: gross ecosystem productivity (GEP) (filled cycles and solid lines), ecosystem respiration (ER) (filled triangles and dashed lines), and net ecosystem CO₂ exchange (NEE) (open cycles and dotted lines), and aboveground biomass: total biomass, graminoid biomass, forb biomass, and biomass ratio of graminiod/forb across 2012 to 2014.

Assessing the Carbon Budget Dynamics of Terrestrial Ecosystems in the Amur River Basin

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
In the context of climate change, understanding the carbon cycle of terrestrial ecosystem is important for projecting the future climate. Toward this end, it is essential to determine the roles of different terrestrial ecosystems as either carbon sources

Reproductive stages in lowbush blueberry (Vaccinium angustifolium) occur earlier with increasing temperature

American Journal of Botany, EarlyView.
Abstract Premise Climate change is altering the timing of many plant phenological events, yet most studies focus on flowering, with less attention given to later reproductive stages such as fruit development and ripening. Vaccinium angustifolium (lowbush blueberry) is an important perennial berry species that may be sensitive to these changes.

The Distributional impact of dams: Evidence from cropland productivity in Africa [PDF]

We examine the distributional impact of major dams on cropland productivity in Africa. As our unit of analysis we use a scientifically based spatial breakdown of the continent that allows one to exactly define regions in terms of their upstream ...

Success of coastal sage scrub restoration is influenced by local adaptations of shrub species

American Journal of Botany, EarlyView.
Abstract Premise Restoring plant communities is increasingly challenging with climate change. While practitioners have traditionally used local seed sources, many are recommending assisted migration, possibly from more extreme environments such as inland rather than coastal environments, for restoration.

Response mechanism of subtropical forest carbon balance to climate change based on InTEC model

Frontiers in Forests and Global Change
IntroductionSubtropical forests play an important role in the global carbon cycle, and their carbon balance response mechanism to climate change not only has important theoretical value, but also has practical reference significance for forest management

Expectations and Reality: The Lived Experiences of Australians With Psychosocial Disability Within the NDIS

Australian Journal of Social Issues, EarlyView.
ABSTRACT While Australia's National Disability Insurance Scheme (NDIS) was founded on principles of choice and control, for people with significant mental health challenges (what the NDIS calls ‘psychosocial disability’) these ideals often remain elusive. Support systems continue to be fractured and in the context of ongoing policy reforms, it is vital
