Shifting in the shadows: Morphofunctional variations of Miconia sellowiana Naudin (Melastomataceae) associated with cave environments

Plant Biology, Volume 28, Issue 2, Page 441-451, March 2026.
Cave environments filter plant traits, selecting thinner, smaller leaves with reduced photosynthetic and vascular structures. Abstract Caves present unique ecological conditions that influence the distribution and adaptation of species, yet studies on cave‐associated vegetation remain limited.

The response of neotropical dragonflies (Insecta: Odonata) to local and regional abiotic factors in small streams of the Amazon [PDF]

, 2019
Since the relative role of local and regional abiotic factors on the Odonata diversity in rainforest streams is still poorly understood, we evaluated the effects of these factors on adult Odonata (Insecta) from preserved and altered streams in the ...

Quantifying leaf herbivory: A guide to methodological trade‐offs and best practices

Ecology, Volume 107, Issue 2, February 2026.
Abstract Leaf herbivory is a ubiquitous ecological interaction that varies significantly in intensity across species, habitats, and biogeographic regions. Although quantification of leaf damage is crucial for understanding many ecological processes, the accuracy and precision of various damage estimation methods used by researchers, including visual ...

Large emissions from floodplain trees close the Amazon methane budget [PDF]

, 2017
Wetlands are the largest global source of atmospheric methane (CH4), a potent greenhouse gas. However, methane emission inventories from the Amazon floodplain, the largest natural geographic source of CH4 in the tropics, consistently underestimate the ...

The role of tropical forest fragment vegetation in maintaining arthropod diversity and spillover to adjacent sugarcane fields O papel da vegetação de fragmentos de floresta tropical na manutenção da diversidade de artrópodes e na sua disseminação para campos de cana‐de‐açúcar adjacentes

Agricultural and Forest Entomology, Volume 28, Issue 1, Page 82-93, February 2026.
Tree diversity increases arthropod richness and the abundance of beneficial arthropod groups within Atlantic Forest fragments. Higher insect richness in forest fragments is associated with greater richness in adjacent sugarcane fields, and both habitats share insect families, suggesting spillover.

Forest Loss Influences Biomass Distribution Across Trophic Groups of Amazonian Stream Insects

Freshwater Biology, Volume 71, Issue 2, February 2026.
ABSTRACT Changes in resource availability caused by deforestation can negatively impact freshwater ecosystems, with implications for trophic chains. We investigated both the direct and indirect effects of forest cover and allochthonous resource availability on the biomass distribution of larvae of aquatic insects (Ephemeroptera, Plecoptera, Trichoptera
