Floristic Diversity and Indicator Species Analysis Along Altitudinal Gradients of the Upper Indus Basin, Northern Pakistan

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
Altitudinal gradients substantially influence floristic diversity and indicator species. Three vegetation communities were identified, each shaped by specific environmental variables. Mantel test shows that altitude, Ca, K, Na are key drivers of species diversity and association.

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 ...

The role of Alpine botanical gardens in integrating germplasm bank collections and mission

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 2, Page 680-692, March 2026.
This study underscores the vital role of Alpine botanical gardens (ABGs) in safeguarding Europe's alpine biodiversity amid climate change and habitat loss. By acting as living laboratories and reservoirs of plant genetic resources, ABGs bridge ex situ and in situ conservation, supporting ecosystem resilience and informing restoration strategies.

A broad typology of dry rainforests on the western slopes of New South Wales [PDF]

open access: yes, 2013
Dry rainforests are those communities that have floristic and structural affinities to mesic rainforests and occur in parts of eastern and northern Australia where rainfall is comparatively low and often highly seasonal.

Century‐long trends in plant diversity of temperate mountain vegetation are modulated along elevation gradient

open access: yesJournal of Ecology, Volume 114, Issue 3, March 2026.
Resurvey studies in mountain forests of the Tatra Mountains (Central Europe) show that plant diversity has increased over the past century, particularly at lower elevations. These shifts were associated more with increased nitrogen deposition and reduced grazing pressure than with direct climate warming.

Testing macroevolutionary predictions of the Grant‐Stebbins model in the origin of Aeschynanthus acuminatus

open access: yesNew Phytologist, Volume 249, Issue 6, Page 3137-3148, March 2026.
Summary The Grant‐Stebbins model predicts that a plant species encountering different pollinators across its range may undergo local adaptation and, subsequently, ecological speciation. We tested whether this could explain the origin of Aeschynanthus acuminatus (Gesneriaceae), a species phylogenetically derived from sunbird specialist ancestors.
