“…Cupania vernalis is considered frequent and common in both vegetation types in open or closed areas of MOF or DOF (Reitz 1980), as is Ilex paraguariensis, which follows the same pattern Rodriguésia 74: e01542021. 2023 (Silva et al 2018). This species was considered an indicator of montane gradient in the FOD of the Serra da Prata (Blum & Roderjan 2007).…”

The study aimed to evaluate the degree of conservation, analyse the structural and floristic similarity of the woody and herbaceous layers of two ecotone forest communities and evaluate the indicator species of a Mixed Ombrophilous Forest (MOF) and Dense Ombrophilous Forest (DOF). We outlined 30 sampling units of 100 m2 in each area (West and East), where we measured three woody and one herbaceous layers. Each species was classified into ecological groups, phytogeographic distribution and conservation status. We selected other 13 studies performed on similar ecosystems to carry out cluster and indicator species analyses. We registered 213 species, arranged into 63 families. The richest families were Myrtaceae, Lauraceae and Fabaceae. In the woody layers Araucaria angustifolia, Allophylus edulis and Cupania vernalis highlighted in West area, while Casearia sylvestris, Cyathea phalerata and Ilex paraguariensis highlighted in East area. Ctenitis paranaensis predominates in herbaceous layer of both areas. Our cluster analysis has formed two groups (MOF; DOF), including both study areas in MOF group. The study areas are in a maturation process. Serra da Baitaca State Park presents high conservationist importance. We list indicator species of montane MOF and DOF forests in the Paraná State, which can be used for monitoring alterations in vegetation caused by environmental changes.

“…Regarding future projections based on climate change, Silva et al (2018) the distribution areas of these species will tend to decrease. This reduction corroborates the estimates by Bergamin et al (2019), who stated that Araucaria Forest areas will continue to be reduced under projected future climate change.…”

With the occurrence of intensive climate change, there is a risk of irreversible damage to global biodiversity, resulting in reduction of geographical distribution and species extinction. The objective of this study was to evaluate the current distribution and the future projection of the areas of occurrence of Curitiba prismatica. Current occurrence data accessed in the SpeciesLink database and scientific studies were collected, which were correlated with the bioclimatic data available in WorldClim, for the current and future periods (2070), in the optimistic (RCP 4.5) and pessimistic scenarios (RCP 8.5) of the HadGEM2-ES model. In the current scenario, a species presents suitability restricted to mixed ombrophilous forest (MOF), with limited distribution to the center-south of the state of Paraná and the north of the state of Santa Catarina. For the future, there were reductions in the areas of climatic susceptibility for the species, both in the optimistic and pessimistic scenarios. In the RCP 4.5 scenario, the predictive reduction was found in the midwest region of Paraná, unlike the RCP 8.5 scenario, which showed a low reduction in this region. Therefore, in the future, areas with high suitability will tend to contract, but restricted to the regions of the first and second plateau of Paraná and the north of Santa Catarina. In this sense, these areas are indicated for commercial planting and in situ and ex situ conservation of the species.

“…The spatial extent of the environmental variables used to train and project models also varied between species, adapting the approach used by Senay et al (2013). An ensemble of three different modelling approaches was used across Africa: Bioclim (Busby, 1991), Maxent (Phillips et al, 2006) and Random Forest (Cutler et al, 2007).…”

Herbaria are renowned as collections of specimens for research in plant taxonomy, plant identification and more recently in plant phylogenetics. The production of Floras and monographs in herbaria is fundamental to the understanding of plant taxonomy and plant biogeography. Herbaria have played an important role in providing the raw geographic data behind plant species distributions which form the basis of the most commonly used biodiversity metric: species richness. Less well recognised is the potential for using comprehensive species checklists, produced by herbaria, as a sampling frame when projecting biodiversity metrics. Functional diversity metrics derived from plant trait values are growing in importance in biodiversity monitoring; however, it is unclear whether the trait-based functional attributes are responsive to changes in species richness in all geographic areas. Modelling of the spatial distribution of trait values is one way to investigate the limits of biodiversity monitoring reliant on trait values. The research outputs of herbaria are arguably an untapped resource of such trait data. Greater digitisation of published Flora treatments as well as continuing digitisation of herbarium specimens is increasingly making these resources more available. With appropriate methods to ameliorate known biases in the species locality and plant trait data held by herbaria, these institutions can play an important role in building spatial models of plant trait distributions. Such models help to establish the relationships between species richness and plant functional diversity metrics in different biomes required for trait-led biodiversity monitoring. Here we present a six-step method to allow data held by herbaria to be used to establish a spatial model of functional diversity metrics at a continental scale.
