Lagged climate‐driven range shifts at species' leading, but not trailing, range edges revealed by multispecies seed addition experiment

open access: yesEcography, EarlyView.
Climate change is causing many species' ranges to shift upslope to higher elevations as species track their climatic requirements. However, many species have not shifted in pace with recent warming (i.e. ‘range stasis'), possibly due to demographic lags or microclimatic buffering.

Predation on Artificial Caterpillars Varies With Vertical Stratification but Not Light Gradients in a Sugar Maple Temperate Forest

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Predation pressure varies vertically, with highest arthropod predation in the understory and highest bird predation in the canopy. Light availability differs across vertical strata, but predation patterns are more strongly influenced by height and forest structure than by light gradients.

Competition and payments to African chiefs on the Gold Coast during the slave trade, 1679‒1704

open access: yesThe Economic History Review, EarlyView.
Abstract The manuscript records of the Royal African Company show that the Company paid African chiefs for access to trade along the caravan routes on the Gold Coast in the seventeenth century. This paper documents and examines these payments. Using an event study, I establish that after the Glorious Revolution in 1688 when the Company's monopoly in ...

When Similar Individuals Don't Attract: Absence of Assortative Mating by Coloration in a Damselfly With Honest Signaling

open access: yesEthology, EarlyView.
In Acanthagrion lancea damselflies, both sexes display blue ornamentation, but do they choose mates based on it? We tested whether mutual mate choice and time constraints influence ornament evolution. Blue coloration correlated with individual quality, but individuals did not choose mates based on color, and this was unaffected by time constraints over

Human Disturbance but Not Predation Risk Is Associated With Increased Vigilance in Roe Deer

open access: yesEthology, EarlyView.
Roe deer vigilance is lower in natural than in modified habitats, decreases with group size, but is not significantly influenced by stable wolf presence, suggesting habitat‐driven risk perception and reliance on spatial avoidance over increased alertness.
