Grass Communities Differ Floristically Under Different Dominant Trees in Savannas in Thailand and Cambodia

open access: yesBiotropica, Volume 58, Issue 2, March 2026.
In total, we recorded 160 unique grass species across four savanna ecosystems dominated by different tree genera. These savannas support distinct grassy assemblages, but common grasses are often shared between ecosystems. ABSTRACT Southeast Asian savannas are some of the least studied ecosystems, with understanding of their function and resilience ...

Hyperspectral leaf reflectance of grasses varies with evolutionary lineage more than with site

open access: yesEcosphere, Volume 16, Issue 4, April 2025.
Abstract To predict ecological responses at broad environmental scales, grass species are commonly grouped into two broad functional types based on photosynthetic pathway. However, closely related species may have distinctive anatomical and physiological attributes that influence ecological responses, beyond those related to photosynthetic pathway ...
