Abstract
Anisophylly is a peculiar leaf trait in some opposite-leaved taxa where opposing leaves are distinctly unequal. This study uses an expert-curated specimen dataset to explore relationships of canopy cover and climate with the presence and intraspecific variation of anisophylly in the genus Triolena. Canopy and climate conditions are investigated between species and within a single species through beta regression models. No relationship was found between canopy cover and anisophylly. However, anisophylly is associated with conditions of high precipitation and high isothermality, which is evident across Triolena and within a single species. In addition, partitioned ecoregion analyses illustrate that different types of anisophyllous leaf states occur in distinct ranges of precipitation and isothermality. Results suggest that anisophylly is associated with climate in Triolena.
期刊介绍：
Ranked by the ISI index, Biotropica is a highly regarded source of original research on the ecology, conservation and management of all tropical ecosystems, and on the evolution, behavior, and population biology of tropical organisms. Published on behalf of the Association of Tropical Biology and Conservation, the journal''s Special Issues and Special Sections quickly become indispensable references for researchers in the field. Biotropica publishes timely Papers, Reviews, Commentaries, and Insights. Commentaries generate thought-provoking ideas that frequently initiate fruitful debate and discussion, while Reviews provide authoritative and analytical overviews of topics of current conservation or ecological importance. The newly instituted category Insights replaces Short Communications.
