Quantitative Support for the Metabolic Load Hypothesis: Metabolic Rate Measures Reveal Host‐Dependent Growth Costs in a Polyphagous Herbivore

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
The metabolic load hypothesis was tested in Polygonia c‐album caterpillars by comparing metabolic costs across three host plants. Larvae feeding on a chemically challenging host showed higher energy demands per unit of growth and reduced performance.

Biogeography and evolutionary patterns of temperate deciduous forests in the Northern Hemisphere

open access: yesEcography, Volume 2025, Issue 12, December 2025.
Temperate deciduous forests of North America, west Eurasia, and east Eurasia share a common origin but were later separated by major geographic barriers. Here, we examine their diverging biodiversity and evolutionary patterns by analyzing floristic richness, phylogenetic turnover, and community evolutionary distinctiveness (CED).
