How can the analysis of reserve dynamics after fire support the phenological insight of Bulbostylis paradoxa (Spreng.) Lindm (Cyperaceae)?

Speedy blooming in Cerrado after fire is not uncommon: New records of Cyperaceae species flowering 24 h after burning

“…terminalis presents a rigid and thick rhizome protected by dead sheaths (Figure 1d). The mechanism by which these species rapidly bloom within a few hours after fire passage likely involves the rapid mobilization of resources from these reserve systems (Medwecka‐Kornaś & Kornaś, 1985; Rosalem et al, 2022). Apparently, this is a unique process associated with the Cyperaceae family and should be further investigated.…”

“…Rhynchospora confusa F.Ballard (synonym Rhynchospora velloziiformis T.Koyama)-an appropriate name considering its confusing morphological vegetative structure-produced flowers in <24 h after fire, as another well-known sedge Bulbostylis paradoxa (Spreng.) Lindm., from Brazilian tropical grasslands and savannas (Fidelis et al, 2019;Rosalem et al, 2022). It is not a novelty that various species in the Cerrado ground layer and in other fire-prone ecosystems around the world have fire-stimulated flowering (Lamont & Downes, 2011;Medwecka-Kornaś & Kornaś, 1985;Pilon et al, 2018;Pyke, 2017;Warming, 1908).…”

How Eutrophication Promotes Exotic Aquatic Plant Invasion in the Lake Littoral Zone?

“…In general, there is a trade-off between competition and tolerance in plants. , Invasive plants are highly competitive, with high capacity for resource acquisition, uptake and assimilation, and rapid relative growth rates (RGR), allowing them to rapidly occupy vacant ecological niches. ,, In contrast, environmentally tolerant plants have low photosynthetic and respiration rates, slow RGR, and large carbon reserves, and they have high tolerance to environmental stress. ,, Thus, biomass and RGR respond to the plant growth rate, while the ramet number and plant height can reflect the ability of plants to expand spatially, and these four traits can be used to predict the competitive ability of plants. , In addition, carbohydrate reserves, such as starch, are key traits for plant maintenance and growth in stressful environments. ,, Phenolics give the plants the ability to withstand external animal feeding, cold weather, and drought events. − Thus, starch and phenolics can be used to address the ability of plants to tolerate external disturbances. Although the high competitive ability of invasive plants is widely recognized, ,, two issues remain unclear: (1) how the trade-off between competition and tolerance of invasive and native plants responds to eutrophication in the littoral zone, and (2) what the implications of this trade-off are for plant invasion of the littoral zone.…”
