Life‐history traits and survival responses to light and water of the rare endemic species Cuphea gaumeri Koehne (Lythraceae)

open access: yesPlant Species Biology, Volume 41, Issue 1, January 2026.
Cuphea gaumeri is a rare endemic species that faces conservation challenges due to climatic variation. Our experiment showed that germination and growth were highest under high water availability and shade. At the same time, reproduction was delayed under low water and shade, and survival was greatest with high water and sunlight exposure.

Interspecific Hybridization in Cuphea

open access: yesHortScience, 1988
Abstract Eighteen interspecific hybrids from eight different Cuphea species have been confirmed morphologically and cytologically. Seven hybrids from reciprocal crosses of various accessions of the herbaceous annual C. procumbens (N = 9) and the semiwoody perennial C. llavea (N = 9) exhibited a relatively high degree of fertility.

DNA Metabarcoding as a Complementary Approach to Traditional Surveys for Monitoring the Plant Diversity in the Amazon canga

open access: yesEnvironmental DNA, Volume 7, Issue 4, July–August 2025.
The canga of the Serra dos Carajás in the Eastern Amazon is a biologically rich region with important iron ore deposits. We used a comprehensive DNA barcode library to test the implementation of DNA metabarcoding for plant species monitoring. In this study, we observed that soil eDNA was more efficient in assessing canga plant diversity, revealing a ...
