“…In Brazil, cloud forests are found in the Serra do Mar and Serra da Mantiqueira regions (Pompeu et al, 2018), near to major urban centres, where a large part of the Brazilian population (Becker et al, 2013), and related public utility problems, are located (Vasconcelos et al, 2019). In this way, these forests are at risk of anthropic disturbances (Ribeiro et al, 2009), and our findings highlight the importance of prioritizing the conservation of these forests in order to offer hydrological services to the population.…”

“…In Brazil, TMCF occur mainly in areas with an altitude above 700 m, in two mountain ranges on the Atlantic coast: the Serra do Mar and the Serra da Mantiqueira (Pompeu et al, 2018). Currently, it is estimated that in Brazil around 60% of the original area of cloud forests has been converted for other uses, which places it in second place in terms of loss of total area of cloud forests (Mulligan, 2010).…”

Regeneration of tropical montane cloud forests increases water yield in the Brazilian Atlantic Forest

et al. 2021

Tropical montane cloud forests (TMCF) have paramount importance with regards to hydrological and ecological functions. Despite such importance in terms of water provision, they are one of the most endangered ecosystems on the planet. One important topic that is still unclear is related to TMCF regeneration: can it recover the hydrological function of such critical ecosystems? In the present paper, the hydrological effects of the natural regeneration of TMCF were examined. We selected three catchments with different degrees of TMCF, and we examined the relationship between the amount of TMCF over time and hydrological variables such as water yields and baseflow using a time series (1984–2011). Our results suggest that the increase in TMCF cover can contribute to increases in water yield. This pattern was found in a catchment with an increase of approximately 20% of forest cover. In catchments with TMCF increase lower than this threshold, water yield and flow path were influenced by hydroclimatic variables such as air temperature and rainfall. The effect of the reduction in water yield, in accordance with the increase in mean temperature, sheds light on possible consequences of climate change on ecosystem services produced in foggy environments. In light of these findings, aiming to increase the water yield, we recommend that regions frequently affected by fog are prioritized for forest restoration or conservation. To ensure significant effects, regeneration and/or successional development of TMCF has to reach at least 20% of a catchment area.

“…From a conservationist point of view, cloud forests are a refugee which has yet to be explored, as their occurrence is restricted to high altitude regions above sea level (Carvalho, Fontes, & Oliveira-Filho, 2000;Bertoncello et al, 2011;Pompeu et al, 2018). There are very few locations in Southeast Brazil which present this characteristic, being more commonly found in Serra da Mantiqueira, Ibitipoca and cities of Aiuruoca, Baependí and Itamonte.…”

“…The region's landscape also has areas with other montane phytophysiognomies in addition to the phytophysiognomies of the Cerrado domain, such as Semi-deciduous forests, Cloud Forests and the Candeais. Limited knowledge about the floristic composition and biogeography of the Cloud Forest (Bertoncello, Yamamoto, Meireles, & Sheperd, 2011;Pompeu et al, 2018) and Candeais makes it difficult to implement an effective management plan which focuses on its conservation (Scolforo, Oliveira, Davide, & Camolesi, 2002), and consequently the fauna which use it which is considered threatened (Moura et al, 2021).…”

Brazil has a high diversity of birds and presents the largest number of threatened bird species in the neotropical region. Even so, there are gaps in the bird knowledge, especially in ecotonal montane regions. Given this panorama, this study aimed to analyse the bird community distribution (richness, composition, and beta diversity between phytophysiognomies) of an ecotonal montane landscape of southeastern Brazil, with the purpose of detecting substitution patterns of bird species on a meso-scale. Using bird data performed during the years 1998 to 2015 in 46 sampling points, we found high bird richness in montane phytophysiognomies along an ecotone between Cerrado and Atlantic Forest hotspots. The composition present species of both domains, with high turnover component. We highlight the field environments and candeais are considered homogeneous and threathened, which would directly affect birds. The present study contributes to future conservation strategies, as it demonstrates ecotonal regions as transition zones and reinforces the need to consider as particular ecological units. These ecotonal regions are key locations for understanding ecological patterns in response to environmental changes or phytophysiognomies. Knowing how partitioning of the composition occurs within an environmental mosaic is essential to understand the limits and distributions of the species and conserve them.

“…This technique relates species observations data to environmental predictor variables using statistical approaches, resulting in an ensemble of ecological requirements of the species (Guisan et al 2017). It has been applied for multiple reasons, such as climate change distribution impacts (Wrege et al 2017), contribution to priority conservation areas (Pompeu et al 2018), biogeographic studies (Werneck et al 2012) and as a tool for the extrapolation of possible potential areas for species cultivation, as in the study by Garcia et al (2014).…”

The use of renewable materials and more sustainable processes are essential to minimize the negative impacts of population growth. Bamboo is a viable alternative, because it is a product with potential properties for wood replacement. However, to achieve a good yield, it is necessary to identify suitable sites for the forestry of the species. This study aimed to forecast favorable areas for the best establishment and development of Bambusa vulgaris and Dendrocalamus giganteus in the Brazilian territory, functioning as a zoning for edaphoclimatic aptitude that can support decision-making. It was performed using georeferenced points of natural occurrence for the species, collected from a virtual herbarium. The environmental variables were extracted from the WorldClim, MOD16 and SoilGrids databases. In order to select the set of variables to be used for modeling each species, a correlation test was performed. From this result, ten environmental variables were used for each species, and non-correlated variables were chosen. A principal component analyses was applied to select the variables that better explained variability. For the distribution map, the Maxent algorithm was used, based on the principle of maximum entropy, evaluated by the AUC and TSS metrics. Bambusa vulgaris presents a large area for adaptation in the Brazilian territory, unlike the Dendrocalamus giganteus species, which showed a limited aptitude area.
