“…Apuleia leiocarpa is an appreciated forest tree for its wood quality and medicinal uses. Its distribution in Brazil, is principally concentrated in the State of Rio de Janeiro, with a slight presence in the state of Minas Gerais, according the current records and also as was mentioned in various studies(Zimmerman et al 2013;Lauterjung et al 2019;Martins et al 2020). The results of our study brought a novelty in relation to areas favored for planting Apuleia leiocarpa, especially in the south-eastern region of the state of Minas Gerais.Climate, soil variables, topography, and photosynthesis activity are important variables.…”

“…Apuleia leiocarpa (Vogel) J. F. Macbr. is a native monoic species of the Brazilian Atlantic Forest domain (Lauterjung et al 2019), and it is widely recognized due to the high quality of the wood, beekeeping, medicinal, landscape, and forestry potential of this species. The A. leiocarpa has a signi cant environmental and industrial role because it is used in wood products and the reforestation of degraded areas.…”

Sustainable wood production is one of the current challenges due to the increasing demand for wood worldwide. Despite, forest planting has proved to be a good solution; the high wood productivity can be achieved only under favorable bioclimatic conditions, which makes this study of great value for government policies. This study aimed to assess the impact of climate on the distribution of Apuleia leiocarpa in Rio de Janeiro and Minas Gerais, Brazil. The Species Distribution Models (SDMs) were performed using the MaxEnt model-based on-field survey of A. leiocarpa (n = 54). Pedological and bioclimatic data were used to identify suitable areas and climate change effects on the distribution of this species. Ours results have shown that the MaxEnt presented a good performance in modelling the distribution of the A. leiocarpa. The temperature was the main controlling variable of the distribution of this species. The pedological models overestimated of the suitable area. Despite that, the results provide useful information to be considered in the future in order to refine the selection of variables for a better characterization of the ecological niche. Regarding the projection of the future A. leiocarpa distribution, there was found an alarming scenario, which it must be taken into the consideration for the local authorities in order to establish a successful species-replanting program.

“…Furthermore, most Atlantic Forest loss occurred in the past 50 to 70 years, which, for many tree species, falls within two to three GLs into the past. So, despite the smaller Atlantic Forest deforestation today, the effects of past habitat loss, fragmentation, and selective logging on these long-lived species may not have had enough time to fully express themselves ( 38 ), which suggests an extinction debt yet to be paid in the coming decades ( 39 , 40 ).…”

Biodiversity is declining globally, yet many biodiversity hotspots still lack comprehensive species conservation assessments. Using multiple International Union for Conservation of Nature (IUCN) Red List criteria to evaluate extinction risks and millions of herbarium and forest inventory records, we present automated conservation assessments for all tree species of the Atlantic Forest biodiversity hotspot, including ~1100 heretofore unassessed species. About 65% of all species and 82% of endemic species are classified as threatened. We rediscovered five species classified as Extinct on the IUCN Red List and identified 13 endemics as possibly extinct. Uncertainties in species information had little influence on the assessments, but using fewer Red List criteria severely underestimated threat levels. We suggest that the conservation status of tropical forests worldwide is worse than previously reported.

“…Intensive historical exploitation and distribution in severely anthropogenic environments are factors contributing to the high f value (Reis et al 2012), a trend described for other species (de Sousa et al 2020;Mariot et al 2020). For example, in a study of six plant species, Lauterjung et al (2019) concluded that heavily exploited species in the past exhibited concerning genetic indices. Another factor that may have infl uenced a high f value is the signifi cant genetic structure found in the evaluated population (Bittencourt and Sebbenn, 2009;Meirmans 2015).…”

Ecological restoration mitigates the negative effects of fragmentation and habitat loss. This practice allows the conservation of key species, such as Ocotea porosa, a tree native to the Araucaria Forest and extremely endangered. A key point in restoration projects is the source of seeds, as well as guidelines for collection. When carried out under technical criteria, the collection allows the maintenance of genetic diversity and adaptive potential in restoration plantations. Given the importance of seed source, genetic diversity, and adaptive potential, this study aimed to define areas and criteria for collecting seeds by characterizing the demography, genetics, and reproductive phenology of an O. porosa population. A plot of 16 hectares was installed in the municipality of Passos Maia, Santa Catarina, Brazil, and a demographic survey of trees with diameter at breast height (DBH) > 15 cm was carried out. Indices of diversity and internal genetic structure (IGS) were estimated using allozyme markers. The reproductive phenology of 67 individuals was evaluated during 8 months. The studied population showed a high density of individuals (10.7 ind. ha-1) with normal diametric distribution. The phenological pattern of the species is regular, seasonal, and annual. The evaluated population showed high genetic diversity, high fixation index, and significant IGS up to 80 meters away. Based on these results, the evaluated fragment can be used as a seed collection area. It has high genetic diversity, density, and area size sufficient to contain several demes. In addition, it is highly recommended that the matrices be at least 80 meters apart to avoid the effects of significant IGS.
