Data from: Historic disturbance regimes promote tree diversity only under low browsing regimes in eastern deciduous forest

Tim Nuttle, Alejandro A. Royo, Mary Beth Adams & Walter P. Carson
Eastern deciduous forests are changing in species composition and diversity outside of classical successional trajectories. Three disturbance mechanisms appear central to this phenomenon: fire frequency is reduced, canopy gaps are smaller, and browsers are more abundant. Which factor is most responsible is a matter of great debate and remains unclear, at least partly because few studies have simultaneously investigated more than one process. We conducted a large-scale experiment in mesophytic forests of West Virginia, USA,...

Data from: Spatial variation in the relationship between performance and metabolic rate in wild juvenile Atlantic salmon

Grethe Robertsen, John D. Armstrong, Keith H. Nislow, Ivar Herfindal, Simon McKelvey & Sigurd Einum
1. Maintenance metabolic rate (MR, the energy cost of self-maintenance) is linked to behavioural traits and fitness and varies substantially within populations. Despite having received much attention, the causes and consequences of this variation remain obscure. 2. Theoretically, such within-population variation in fitness-related traits can be maintained by environmental heterogeneity in selection patterns, but for MR this has rarely been tested in nature. 3. Here, we experimentally test if the relationship between MR and performance...
