Phylogenetic insights into Dyopsinae (Lepidoptera, Noctuidae): Resolving the systematic position of Thiacidinae

open access: yesSystematic Entomology, Volume 51, Issue 2, April‐June 2026.
In this study, a new phylogenetic study reclassifies the moth subfamilies Dyopsinae and Thiacidinae. For the first time, Thiacidas postica—the type species of Thiacidinae—was sequenced and shown to belong within Dyopsinae, in the Ceroctena clade. As a result, Thiacidinae is reinstated as the tribe Thiacidini (stat. nov.) within Dyopsinae.

Insect‐Derived Bioactives for Glycemic Control and Gut Health: A Review

open access: yesFood Frontiers, Volume 7, Issue 2, March 2026.
Insect‐derived bioactive compounds (e.g., peptides, polysaccharides) effectively regulate blood glucose through dual mechanisms: directly inhibiting carbohydrate‐digesting enzymes and glucose transporters, and indirectly modulating gut microbiota to enhance intestinal barrier integrity.

Patterns of Tree Species Abundance and Diversity on Urban Sidewalks in Macapá, Amapá, Brazil

open access: yesEcological Research, Volume 41, Issue 2, March 2026.
This study presents the first systematic inventory of street trees in Macapá, Northeastern Brazilian Amazon. Results reveal a dominance of exotic and fruit‐bearing species, low tree density, and a replacement of large canopy trees by smaller ones, indicating potential losses in ecosystem services and the need for more biodiversity‐focused afforestation

Soil Properties and Plant Species Identity Independently Influence Arbuscular Mycorrhizal Fungal Composition Across Lowland Tropical Forests

open access: yesBiotropica, Volume 58, Issue 2, March 2026.
We found that plant species identity and soil properties, especially soil phosphorus availability, independently structured arbuscular mycorrhizal fungal (AMF) community composition in tropical forests across central Panama. We also found that soil nutrient availability may mediate the interaction networks between plants and AMF. ABSTRACT Plant species

Distributional patterns of cecropia (Cecropiaceae): a panbiogeographic analysis

open access: yesCaldasia, 1997
A panbiogeographic analysis of the distributional patterns of 60 species of Cecropia was carried out. Based on the distributional ranges of 36 species, we found eight generalized tracks for Cecropia species.

A New Species of Neotropical Carpenter Ant in the Genus Camponotus (Hymenoptera: Formicidae), Apparently without Major Workers

open access: yesPsyche: A Journal of Entomology, 2012
We describe a new species of carpenter ants from Ecuador, which apparently has an obligatory relationship with the ant plants Cecropia membranacea Trécul, C. herthae Diels and C. marginalis Cuatrec.

Interspecific variation in leaf phenology and its relationship with plant traits in a seasonal tropical forest

open access: yesFunctional Ecology, Volume 40, Issue 2, Page 433-450, February 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Leaf phenology plays an important role in plant life‐history strategies and in determining ecosystem‐level fluxes of carbon and water. In seasonal tropical forests, leaf phenology is highly variable among tree species, but limited quantitative data have hindered our ...

The Habitat Affects the Ecological Interactions between Azteca Forel (Hymenoptera: Formicidae) and Cecropia Loefl. (Urticaceae Juss.)

open access: yesSociobiology, 2018
In order to understand the effects of human impacts on structure and functioning of tropical forests, we should consider studies on animal-plant interactions such as antplant mutualistic interactions.We investigated the mutualistic interactions between ...
