The Evolution of Hutchinsonian Climatic Niche Hypervolumes in Gymnosperms

open access: yesGlobal Ecology and Biogeography, Volume 35, Issue 6, June 2026.
ABSTRACT Aim The niche is a fundamental concept in theoretical and experimental ecology and is used to describe a wide range of ecological processes from species' interactions with the environment to community assemblies. A common way to represent the niche is through a multidimensional geometry known as the Hutchinsonian niche hypervolume.

Dietary Overlap of Sympatric Polyphagous Alpine Grasshoppers Includes Invasive Plant Species

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
The diets of three sympatric grasshopper species were compared using mandible morphological analysis, microhistological examination, and DNA metabarcoding of gut contents. Although mandible morphology differed across species and sexes, dietary divergence was not evident.

Implications of leaf and shoot physiology in Podocarpaceae

open access: yes, 2003
The morphology of many genera in the Podocarpaceae has converged towards compression and reorientation of short shoots to form bilaterally compressed photosynthetic surfaces analogous to broad leaves in angiosperms.
