Defensive Strategies of a Noctuid Caterpillar in a Myrmecophytic Plant: are Dyops Larvae Immune to Azteca Ants?

open access: yesSociobiology, 2018
Immature stages of insects are generally susceptive to their natural enemies, but many species developed defensive and evasive mechanisms to circumvent predation. Gregarious larvae of the noctuid moth Dyops cf. cuprescens feed on leaves of young Cecropia

Arboreal ants use the "Velcro(R) principle" to capture very large prey. [PDF]

open access: yesPLoS ONE, 2010
Plant-ants live in a mutualistic association with host plants known as "myrmecophytes" that provide them with a nesting place and sometimes with extra-floral nectar (EFN) and/or food bodies (FBs); the ants can also attend sap-sucking Hemiptera for their ...

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

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 ...

Forest structure and connectivity drive the functional recovery of seed rain

open access: yesJournal of Ecology, Volume 114, Issue 2, February 2026.
Local forest structure and landscape‐scale connectivity shape distinct but complementary pathways of the functional recovery of seed rain in tropical forests. Structural complexity promotes functionally diverse plant–frugivore interactions locally, while connectivity facilitates the arrival of late‐successional seeds from external sources.

Dynamics and trajectories of secondary succession in Central Amazonia [PDF]

open access: yesBoletim do Museu Paraense Emílio Goeldi. Ciências Naturais, 2012
Land use history is a primary driver of secondary succession in the Central Amazon, resulting in the establishment of distinct trajectories differing in structure, composition, biomass and dynamics. Intensive use with prescribed fire to maintain pastures

Transcriptomic, proteomic and biochemical comparison of luminescent and non‐luminescent Keroplatinae larvae (Diptera: Keroplatidae)

open access: yesInsect Molecular Biology, Volume 35, Issue 1, Page 34-47, February 2026.
Transcriptomic and proteomic comparison of luminescent O. fultoni and non‐luminescent Neoditomyia sp show that the substrate binding fraction (SBF) has a similar abundance of hexamerins and the presence of flavin‐dependent reductases. In addition to the high content of keroplatin, SBF also contains considerable amounts of riboflavin and displays ...

Temperature and Morphology Affect the Performance and Cost of Flight in Spruce Budworm Females

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
Forewing length and wing surface are the key morphological traits to explain the biomechanics of the flight performance in spruce budworm. Large budworm females benefit from more energy reserves that can be allocated daily to flight and a relative energy saving during flight due to their mass.
