Modifications in fire frequency impact belowground plant components in old-growth grasslands, posing risks to their resilience. [PDF]
Am J BotAbstract Premise In edaphic old‐growth grasslands, the low nutrient content of the soil restricts plant species establishment. Additionally, fire remains an important factor in shaping vegetation structure and belowground biomass investment in old‐growth grasslands, such as the campos rupestres.

Biosilicification in monocots: Comparative analysis highlights contrasting patterns of deposition. [PDF]
Am J BotAbstract Premise New insights into biomineral uptake and sequestration are important for understanding how plants grow. Some plants accumulate silica accretions in precise locations in particular cells. Among monocots, controlled biosilicification occurs in several different forms and is restricted to commelinids and orchids. Methods We utilized energy‐

Global analysis of Poales diversification - parallel evolution in space and time into open and closed habitats. [PDF]
New PhytolSummary Poales are one of the most species‐rich, ecologically and economically important orders of plants and often characterise open habitats, enabled by unique suites of traits. We test six hypotheses regarding the evolution and assembly of Poales in open and closed habitats throughout the world, and examine whether diversification patterns ...

A First Quantification of Plant Endemism in the Manica Highlands (Zimbabwe-Mozambique) and the Significance of Open Habitats. [PDF]
Ecol EvolWe present here the first quantitative assessment of plant endemics from the Manica Highlands (Zimbabwe‐Mozambique), totalling 216 taxa, representing over 9% of the estimated total flora. A major finding is that 173 (80%) endemic taxa are principally or entirely confined to open montane habitats such as grassland, bare rock, crags and scrub or dwarf ...

A mosaic of colors: The influence of biotic and abiotic factors shaping flower color diversity across a tropical mountain ecosystem. [PDF]
Am J BotAbstract Premise Flower color diversity within communities is shaped by biotic and abiotic factors. Pollinators often prefer specific colors, and floral pigments also help protect against abiotic factors such as ultraviolet (UV) radiation, precipitation, and temperature.

American Journal of Botany, Volume 108, Issue 7, Page 1066-1086, July 2021., 2021 Premise Resolving relationships within order Commelinales has posed quite a challenge, as reflected in its unstable infra‐familial classification. Thus, we investigated (1) relationships across families and genera of Commelinales; (2) phylogenetic placement of never‐before sequenced genera; (3) how well off‐target plastid data integrate with other ...

Rheophytes of the middle Caquetá River, Colombian Amazonia
Caldasia, 2022 We studied the rheophytic vascular flora of the middle Caquetá River basin in the Colombian Amazon, by sampling along the margins and islands of its two largest rapids, Angostura and Araracuara, along the rapids of the black-water Yarí river, its second ...
