Macroecological variation in movement profiles: body size does not explain it all

The paper analyzes movement profiles across vertebrates to show that body size does not fully explain movement distances, highlighting the role of ecological and biomechanical constraints.

Linking intrinsic scales of ecological processes to characteristic scales of biodiversity and functioning patterns

This study uses simulations to explore how different ecological process scales affect biodiversity and ecosystem functioning patterns, finding that dispersal and species interactions have opposing effects on spatial heterogeneity.

Dispersal across habitat boundaries: uncovering the demographic fates of populations in unsuitable habitat

The paper investigates the demographic outcomes of individuals crossing habitat boundaries in a fragmented grassland, finding that seed dormancy allows patch specialists to persist in unsuitable habitat and potentially reach suitable patches, while invasive species struggle to establish in patches.

Climate warming weakens local adaptation

The paper quantifies how climate change impacts population performance by analyzing temperature and precipitation effects, finding that local adaptation to temperature is critical and deviations reduce performance.

Environmental variability and the evolution of bet hedging strategies

This study examines bet-hedging strategies in plants, finding that dormancy and dispersal evolve to address different environmental heterogeneities rather than covarying as predicted.

An experimental manipulation of species’ phenologies overturns competitive hierarchies

The paper manipulates germination timing of two grass species to show that phenological separation reduces within-year coexistence but allows long-term coexistence through annual variation.
