Temporal dynamics in functional fruit traits of native and invasive fleshy fruited plants in subtropical Andean forests

Functional Ecology, Volume 40, Issue 5, Page 1221-1232, May 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Fruits encompass the energetic and material flow between both interacting parties in frugivore‐mediated seed dispersal. Since fruit traits matter in frugivores' foraging decisions, the temporal dynamics of fruit traits might influence interaction outcomes.

Community‐level effects of Müllerian mimicry on pollinator diversity and functioning

Functional Ecology, Volume 40, Issue 3, Page 599-610, March 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Müllerian mimicry, a mutualistic interaction in which harmful species evolve similar warning signals, is often accompanied by niche divergence among mimetic species. While these aspects have traditionally been studied in an evolutionary context, their community‐level ...

Movement Strategies of Neotropical Nectarivorous Birds: Insights From High‐Andean Hummingbirds and Flowerpiercers

Biotropica, Volume 58, Issue 1, January 2026.
Nectar is a highly variable, mostly unpredictable resource in tropical mountains. How do nectarivorous birds such as this male Great Sapphirewing cope? Fine‐scaled tracking of hummingbirds and flowerpiercers shows flexibility in daily movement strategies in the high Andes, possibly in response to fluctuating local conditions such as weather and ...

Phylogenomic insights into helmet evolution in neotropical treehoppers (Hemiptera: Membracidae): Conserved morphological complexity across five subfamilies

Systematic Entomology, Volume 51, Issue 1, January‐March 2026.
Phylogenomic analyses of 2539 nuclear loci reveal robust relationships among major Membracidae lineages. Helmet shape complexity shows strong phylogenetic conservatism across genera, tribes and subfamilies. Pronotal modularity evolves across lineages, highlighting the developmental diversity of treehopper morphologies. Abstract We utilized genomic data

Influence of sex‐organ positions on pollen transfer and self‐interference in plants with stylar polymorphisms: An experimental approach using three‐dimensional printed flowers

Functional Ecology, Volume 39, Issue 9, Page 2526-2538, September 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Heterostylous plants are defined by the reciprocal positioning of stigmas and anthers in floral morphs—a trait proposed by Darwin to enhance the efficiency of disassortative (intermorph) pollen transfer.

Community‐level trait variation of epiphytic bryophytes supports trade‐off aligned with leaf‐economic spectrum in vertically stratified tropical montane cloud forest canopies

Functional Ecology, Volume 39, Issue 9, Page 2300-2313, September 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Tropical montane cloud forests are among the most biodiverse ecosystems on earth and are vulnerable to climate change due to reliance on atmospheric moisture. Epiphytic bryophytes (i.e.

Strong scale‐dependent relationships between fine‐root function and soil properties uncovered with spatially coupled sampling

New Phytologist, Volume 246, Issue 6, Page 2506-2521, June 2025.
Summary Substantial fine‐root trait variation is found at fine spatial scales but rarely linked to edaphic variation. We assessed the spatial scales of variation in fine‐root traits and adjacent soils using a spatially coupled, nested sampling scheme along a fertility gradient in a seasonally dry tropical forest tree, Handroanthus ochraceus.

Pyraloid Moth Assemblages Exhibit Complex Morphological Patterns Across an Ecuadorian Mountainous Forest

Biotropica, Volume 57, Issue 3, May 2025.
In this study, we examined how morphological traits and species diversity of Pyraloidea moths vary with temperature and vegetation cover along an Andean rainforest gradient in Ecuador. Using 4161 individuals (212 species) and cross‐validating with a larger dataset of 10,337 individuals (749 morpho‐species), we found a near‐linear decrease in diversity ...

Geographic variation in developmental plasticity among populations of the canyon treefrog in response to temperature and pond‐drying

Journal of Zoology, Volume 324, Issue 2, Page 103-117, October 2024.
This study focuses on the responses of the canyon tree frog (Dryophytes arenicolor) larvae to temperature and pond‐drying. Conducting a common garden experiment with larvae from three distinct populations, we found significant geographic variation in plastic responses and observed that populations exhibit specific responses to each treatment in both ...
