“…To reduce the potential effects of including species from different phylogenetic lineages, we focus on one single lineage of abundant, diverse and ecologically important plants in the study area: bamboos (Fadrique et al 2020). Woody bamboos (family Poaceae, subfamily Bambusoideae, tribe Bambuseae) are a native and conspicuous element of many forests from the lowland Amazon up to 4000 m a.s.l.…”

Widespread changes in temperature and precipitation patterns present plant species with new and combined stresses that affect their performance and distribution. Functional traits are indicators of plant resource use–acquisition strategies and thus they are commonly used to understand the geographic distributions of plant species and species' potential responses to climate change. To date, most studies have targeted a few easy‐to‐measure leaf traits even though other traits, such as climatic tolerances, could provide valuable information directly related with species' current and future distributions. Here, we measured both leaf functional traits and indices of physiological tolerance to heat (T50) and drought (cell membrane stability) in 28 woody bamboo populations from 22 narrow‐ranged species along a > 3000 m elevation gradient in the southern Peruvian Andes. We found that bamboo leaf functional traits remain fairly constant with a combination indicative of an acquisitive strategy (low leaf mass area and high nitrogen per mass) along the elevation gradient, despite drastic changes in environment and fast species turnover. Heat and drought tolerances of bamboos varied widely along the gradient and were negatively correlated to each other. Drought tolerance of bamboo populations was positively related with elevation and with precipitation seasonality while heat tolerance decreased at higher, colder elevations. When analyzed for individuals within each species or for individuals within each elevation, the two metrics of climatic tolerances did not show a consistent relationship, contrasting with the expectation of a potential tradeoff between heat and drought tolerance. We also found that the measured leaf functional traits were not good predictors of climatic tolerances. Our results illustrate the diversity and complexity of the relationships between functional strategies and environmental gradients and highlight the limitations of using basic (i.e. ‘soft') leaf traits to understand plant distributions and climatic tolerances.

“…Individual clumps were visually defined in the field. Although we did not follow any specific rules during our data collection in 2017, in order to increase the representation and visibility of bamboo in forest surveys, a recently published protocol provides guidelines for sampling and monitoring bamboo in tropical forests (Fadrique et al., 2020).…”

Forest fires facilitate growth of herbaceous bamboos in central Amazonia

et al. 2021

Severe droughts in Amazonia caused by El Niño and Atlantic dipole events are expected to become more frequent due to anthropogenic climate change. These droughts lead the tropical forests of central Amazonia to become increasingly exposed to fire. Forest-fire disturbances can create ideal scenarios for opportunistic plants, such as some bamboos. In this study, we investigate the influence of forest fires, canopy openness, and vertical distance to channel network (VDCN-a proxy for soil moisture availability) on the growth and expansion of Olyra latifolia and Taquara micrantha in the municipality of Autazes, Amazonas, Brazil. The density of these herbaceous bamboos was represented by the density of clumps (clumps ha -1 ) and of culms (culms ha -1 ), while bamboo growth was expressed as culms per clump and the average height of clumps. Forest disturbed by fire had a density of culms 116% higher than the value found in the control treatment. Plots affected by fire, which were at lower VDCN, showed evidence of higher potential for fire ignition in the low areas.The average number of culms per clump was significantly higher in post-burn forests. While canopy opening revealed a significant positive linear relationship with the abundance of herbaceous bamboo in our study area, VDCN had a negative effect on bamboo growth, suggesting that, in addition to fire, light in the understory and access to the water table are limiting factors for these two species in the upland forests of central Amazonia.

“…The bamboo-driven structural changes in forest communities are generally triggered by changes to tree recruitment and tree mortality (Guilherme et al, 2004). Bamboos do not affect all forest species and their maturity stages alike (Lacerda and Kellermann, 2019;Fadrique et al, 2020). Tall canopy and pioneer trees are the least affected as they both have the ability to break free from the dominance caused by bamboos, while the understory trees suffer the worst.…”
