ABSTRACT Aim Belowground biomass, including roots and belowground bud‐bearing organs, is crucial in tropical open ecosystems, particularly during post‐fire regeneration. However, we still do not understand how variation fire regime modulates the allocation of biomass these parts. In two distinct regimes, investigated aboveground as well distribution composition organs ecosystems. Location Five ecosystems Brazil (from northern to southeast Brazil). Methods We assessed above‐ plant across 100 plots (10 for each treatment conditions i.e. frequently burnt excluded, at five sites total). sorted out live aboveground, coarse (> 2 mm) fine (< mm). Bud‐bearing were classified into morphological categories (e.g., xylopodia, woody rhizome fleshy rhizome). Results Fire‐excluded areas had a lower root‐to‐shoot ratio total belowground‐to‐aboveground than burnt. The root organ remained unchanged with exclusion. changed towards lateral spread, such rhizomes, when was excluded. Conclusions More 10 years exclusion did affect but Even after 12 exclusion, present community, ensuring resilience even if they burned regularly.

Practitioner tools for addressing knowing–doing gaps in seed‐based restoration

The increasing impact of global change drivers, including climate change, wildfires, and invasive plant species, is significantly transforming native communities in the western United States, prompting a strong focus on ecological restoration. One prominent restoration strategy involves using seeds. However, achieving successful seed‐based faces several logistical challenges. Ecological obstacles can include seed predation, unsuccessful germination, early seedling mortality, while issues involve ensuring availability suitability seeds for specific sites. To address these challenges, range tools, species selection climate‐adapted handling resources, trait databases, information portals, have been developed to assist practitioners. Despite significant gap exists between research produced by scientists its application Bridging this “knowing–doing” requires making more available, relevant, current, understandable end users. Our goal highlight online tools that knowing–doing provide resource individuals who are interested in: (1) learning about available (2) creating Efforts improve tool usability, training, encourage knowledge exchange essential enhancing outcomes effectively mitigate effects change.
