Habitat‐Dependent Effects of Canopy Cover on Insect Predation in a Tropical Dry Forest Landscape

open access: yesEcological Research, Volume 41, Issue 1, January 2026.
Our results reveal that arthropods, particularly chewing arthropods, were the dominant predators, and their activity was strongly influenced by both habitat type and canopy cover. Predation probability increased with canopy cover in forest plots but decreased in silvo‐pastures, highlighting an important interaction between vegetation structure and ...

Influence of Cadmium and Arbuscular Mycorrhizae on Growth and Chlorophyll Content in Theobroma cacao and Theobroma grandiflorum Plants

open access: yesAdvances in Agriculture, Volume 2026, Issue 1, 2026.
Inoculation of arbuscular mycorrhizal fungi (AMF) has important benefits, not only for plant growth but also for reducing Cd absorption in Theobroma plants. This study aimed to investigate the influence of cadmium (Cd) and arbuscular mycorrhizae (AM) on growth and chlorophyll content (CC) in Theobroma plants.
