A government wants to exploit a renewable resource, yielding a time-varying flow of rent, by leasing it at a fixed rate. Leasing contracts can be expropriated before expiration, albeit at a cost. To minimise transactions costs and avoid the ‘resource curse’ the government would prefer to enter into an infinitely long contract (i.e.

Unique high Arctic methane metabolizing community revealed through in situ 13CH4-DNA-SIP enrichment in concert with genome binning

open access: yesScientific Reports, 2022
Greenhouse gas (GHG) emissions from Arctic permafrost soils create a positive feedback loop of climate warming and further GHG emissions. Active methane uptake in these soils can reduce the impact of GHG on future Arctic warming potential.

The unpredictably eruptive dynamics of spruce budworm populations in eastern Canada

open access: yesPopulation Ecology, EarlyView.
We examine historical population data for spruce budworm from several locations through the period 1930–1997, and use density‐dependent recruitment curves to test whether the pattern of population growth over time is more consistent with Royama's (1984; Ecological Monographs 54:429–462) linear R(t) model of harmonic oscillation at Green River New ...
