Historical vertebrate herbivory drives ontogenetic shifts in plant defense across oceanic islands

Ecology, Volume 107, Issue 7, July 2026.
Abstract Islands with contrasting herbivore histories provide a natural framework to investigate the evolution of plant defenses. Theory predicts that on islands with historically intense vertebrate herbivory, juveniles maintain strong defenses while adults may reduce them once out of reach, whereas islands lacking vertebrate browsers show minimal ...

Forest Responses to Fire Regime in the Humid Chaco of Paraguay

Applied Vegetation Science, Volume 29, Issue 3, July/September 2026.
Fire regimes are increasingly shaping vegetation dynamics in the Humid Chaco of Paraguay, a poorly studied fire‐prone region. Our findings highlight resprouting as a key functional trait associated with fire disturbance. Although vegetation structure varied little among regimes, preserving forest patches may help maintain landscape heterogeneity and ...
