Pollinator efficiency, rather than bee decline, explains a shift to hummingbird pollination in tropical montane forests

open access: yesNew Phytologist, Volume 251, Issue 4, Page 2237-2247, August 2026.
Hummingbird pollination is a hallmark of American plant diversity and has long been thought to evolve in tropical mountains due to declining bee activity. Using sister species of Costus specialized on bees (C. kuntzei) and hummingbirds (C. wilsonii), we show that this shift is not driven by reduced bee visitation with elevation, but by greater ...

Changes in Aperiodic (1/f Slope) Activity During a Picture‐Word Interference Task: Effects of Congruency and Sequence Manipulations

open access: yesPsychophysiology, Volume 63, Issue 8, August 2026.
ABSTRACT Aperiodic neural activity (1/f EEG) has been proposed to reflect the balance between excitatory and inhibitory (E/I) inputs, with steeper spectral slopes reflecting increased inhibition and flatter slopes indicating excitation. This activity is also thought to reflect the temporal coordination of neural firing, offering insights into ...
