Neotropical Cave Entrances as Environmental Filters for Vascular Plant Communities Along Low‐Light and Soil Resource Gradients

open access: yesJournal of Vegetation Science, Volume 37, Issue 4, July/August 2026.
Conceptual representation of cave entrances as ecological filters along the epigean forest–cave continuum in Neotropical quartzite systems. Vascular plant richness declines sharply from the well‐lit, organic‐rich forest toward the low‐light, quartz‐rich cave interior, while community composition and β‐diversity are shaped by the combined effects of ...

Height and phytotelm size affect the invertebrate communities of epiphytic bromeliads in the Amazon rainforest

open access: yesEcological Entomology, Volume 51, Issue 2, Page 221-234, April 2026.
The height at which epiphytic bromeliads are found affects the invertebrate community composition within them. The size of epiphytic bromeliads is positively correlated with species richness of both aquatic and terrestrial invertebrates. Whether bromeliads were found in primary or secondary forest did not have a significant effect on the community of ...

Human Eye Visualization With an Attention Mechanism: Enhancing Flower Detection and Classification With Visual Attention and Photometric Principles Inspired by Human Vision

open access: yesEngineering Reports, Volume 8, Issue 3, March 2026.
The graphical abstract illustrates a flower classification model relying on the human visual system. The model captures images, simulates visual attention and photometric perception, extracts features of shape and color, and classifies flowers by using an optimized neural network that enhances recognition accuracy by mimicking the human eye's focusing ...
