The Journal of Wildlife Management, EarlyView.Caribou forage lichens were present in post‐burn lodgepole pine stands multiple decades before stem‐density was likely open enough to attract wintering caribou. We posit that the prolonged self‐thinning of lodgepole pine after fire may be a greater limiting factor than lichen abundance for habitat recovery in lodgepole pine forests.

Land Degradation &Development, EarlyView.ABSTRACT Land‐use changes related to cultivated land significantly affect the regional carbon budget in major grain‐producing regions, yet the ecological network characteristics of cultivated land carbon flows remain insufficiently understood. This study developed an integrated framework that combined ecological network analysis with spatial analysis ...

International Journal of Osteoarchaeology, EarlyView.ABSTRACT This study examines faunal assemblages from paired semisubterranean houses and middens at 10 Early Inuit sites spanning the North American Arctic (ca. 1200–1500 ce) to evaluate whether local resource bases or other factors primarily structure zooarchaeological variability.

Oikos, EarlyView.Biodiversity can underpin stability in communities, allowing them to withstand environmental fluctuations without changes in aggregate properties like total abundance or biomass. We investigated the influence of biodiversity on two crucial population‐level mechanisms governing abundance stability in mesopredatory coral reef fishes: 1) ‘community ...

Interplanetary frontiers: terraforming from an invasion science perspective
Oikos, EarlyView.The pursuit of a multi‐planetary existence represents one of humanity's greatest frontiers. If applied justly, it offers an opportunity to extend its civilization's lifespan amid escalating sustainability crises on Earth. One approach increasingly gaining traction is terraforming, a hitherto theoretical ecological and evolutionary experiment revolving ...

Mesoclimatic origin affects alpine plant germination but not its plasticity
Oikos, EarlyView.Mountain ecosystems are disproportionately exposed to global warming, which may put alpine plant species in particular at risk. Plant species' migration and persistence depend on successful seed regeneration, with demographic traits such as germination being strongly sensitive to both present and ancestral climate.

Saving Planetary Systems: Dead Zones and Planetary Migration [PDF]
Astrophysical Journal, 2007 The tidal interaction between a disk and a planet leads to the planet's migration. A long-standing question regarding this mechanism is how to stop the migration before planets plunge into their central stars. In this paper, we propose a new, simple mechanism to significantly slow down planet migration, and test the possibility by using a hybrid ...

The dynamical role of the circumplanetary disc in planetary migration [PDF]
Astronomy and Astrophysics, 2009 Numerical simulations of planets embedded in protoplanetary gaseous discs are a precious tool for studying the planetary migration ; however, some approximations have to be made. Most often, the selfgravity of the gas is neglected. In that case, it is not clear in the literature how the material inside the Roche lobe of the planet should be taken into ...

Migration-Induced Architectures of Planetary Systems [PDF]
Origins of Life and Evolution of Biospheres, 2012 The recent increase in number of known multi-planet systems gives a unique opportunity to study the processes responsible for planetary formation and evolution. Special attention is given to the occurrence of mean-motion resonances, because they carry important information about the history of the planetary systems. At the early stages of the evolution,

Planetary Migration in Protoplanetary Disks [PDF]
, 2018 The known exoplanet population displays a great diversity of orbital architectures, and explaining the origin of this is a major challenge for planet formation theories. The gravitational interaction between young planets and their protoplanetary disks provides one way in which planetary orbits can be shaped during the formation epoch.
