Data from: A quantitative framework to estimate the relative importance of environment, spatial variation and patch connectivity in driving community compositionViviane F. Monteiro, Paulo C. Paiva & Pedro R. Peres-Neto
Perhaps the most widely used quantitative approach in metacommunity ecology is the estimation of the importance of local environment vs. spatial structuring using the variation partitioning framework. Contrary to metapopulation models, however, current empirical studies of metacommunity structure using variation partitioning assume a space-for-dispersal substitution due to the lack of analytical frameworks that incorporate patch connectivity predictors of dispersal dynamics. Here, a method is presented that allows estimating the relative importance of environment, spatial variation...
Data from: Northeastern North America as a potential refugium for boreal forests in a warming climateLoïc D'Orangeville, Louis Duchesne, Daniel Houle, Daniel Kneeshaw, Benoît Côté & Neil Pederson
High precipitation in boreal northeastern North America could help forests withstand the expected temperature-driven increase in evaporative demand, but definitive evidence is lacking. Using a network of tree-ring collections from 16,450 stands across 583,000 km2 of boreal forests in Québec, Canada, we observe a latitudinal shift in the correlation of black spruce growth with temperature and reduced precipitation, from negative south of 49°N to largely positive to the north of that latitude. Our results suggest...
Females in many animal taxa incur significant costs from mating in the form of injury or infection, which can drastically reduce survival. Therefore, immune function during reproduction can be important in determining lifetime fitness. Trade-offs between reproduction and immunity have been extensively studied, yet a growing number of studies demonstrate that mated females have a stronger immune response than virgins. Here, we use the Texas field cricket, Gryllus texensis, to test multiple hypotheses proposed to...
Data from: Shade tolerance and the functional trait - demography relationship in temperate and boreal forestsAitor Ameztegui, Alain Paquette, Bill Shipley, Michael Heym, Christian Messier & Dominique Gravel
Despite being instrumental in forest ecology, the definition and nature of shade tolerance are complex and not beyond controversy. Moreover, the role it plays in the trait – demography relationship remains unclear. Here, we hypothesize that shade tolerance can be achieved by alternative combinations of traits depending on the species’ functional group (evergreen vs. deciduous species), and that its ability to explain the array of traits involved in demography will also vary between these two...
Data from: Partitioning the effect of composition and diversity of tree communities on leaf litter decomposition and soil respirationMark Davidson Jewell, Bill Shipley, Etienne Low-Decarie, Cornelia M. Tobner, Alain Paquette, Christian Messier & Peter B. Reich
The decomposition of plant material is an important ecosystem process influencing both carbon cycling and soil nutrient availability. Quantifying how plant diversity affects decomposition is thus crucial for predicting the effect of the global decline in plant diversity on ecosystem functioning. Plant diversity could affect the decomposition process both directly through the diversity of the litter, and/or indirectly through the diversity of the host plant community and its affect on the decomposition environment. Using a...
