Conspecific Negative Distance‐Dependence and New Zealand Podocarp Forest Dynamics

open access: yesAustral Ecology, Volume 51, Issue 9, September 2026.
ABSTRACT The Janzen‐Connell hypothesis proposed that conspecific negative density or distance dependence (CNDDD) helps maintain the species richness of tropical rainforests through the action of specialist natural enemies that suppress conspecific recruitment beneath canopy trees.

Migration of the Butterfly Panacea prola (Nymphalidae: Biblidinae) in the Southeastern Peruvian Amazon

open access: yesBiotropica, Volume 58, Issue 5, September 2026.
We document an annual dry season migration of the butterfly Panacea prola across a 5‐year period at a lowland Amazonian site in southeastern Peru, adding to our extremely limited knowledge of insect migration in the world's largest and most biodiverse rainforest.

Human Disturbances and Woody Flora Diversity Along a Caatinga–Brejo de Altitude Gradient in Northeastern Brazil

open access: yesBiotropica, Volume 58, Issue 5, September 2026.
ABSTRACT Tropical dry forests are among the ecosystems most threatened by human activities worldwide. The Caatinga, a seasonally dry tropical forest restricted to northeastern Brazil, exemplifies this scenario, as local human populations strongly depend on forest resources.

Dovetailing the Genetic, Developmental and Functional Bases of the Adaptation of Stomatal Traits to Climate

open access: yesEcology Letters, Volume 29, Issue 9, September 2026.
For diverse ecotypes of Arabidopsis thaliana grown in a common garden, we tested a three‐tier approach to clarifying the drivers of gmax. Our analyses yielded novel findings for this wide‐ranging species: a larger gmax was achieved through greater epidermal allocation to stomata, via a higher stomatal index and smaller epidermal pavement cells; larger ...

From hindrance to indirect protection: Ant‐mediated enemy‐free space for gall midges (Cecidomyiidae) on Macaranga myrmecophytes (Euphorbiaceae)

open access: yesEntomological Science, Volume 29, Issue 3, September 2026.
Ant presence was associated with lower gall density on Macaranga beccariana, whereas trees lacking ant defense had more galls and showed different parasitism patterns. Results from this natural experiment suggest that plant‐ants may indirectly influence gall midges through their effects on multitrophic interactions.

Forest disturbance and the spread of invasive species disrupt diel activity patterns in New Guinea ant communities

open access: yesInsect Conservation and Diversity, Volume 19, Issue 5, Page 1140-1155, September 2026.
Primary forests hosted more diurnal species and exhibited significant diel specialization. Secondary forests were less species‐rich, dominated by invasive ants, with reduced diel partitioning and more species active at night. Although the overall ant activity was higher during the day, this pattern was stratum‐dependent: arboreal and terrestrial ants ...
