“…The world is heading towards the SSP5-8.5 scenario, which predicts an increase in temperature of 1.9 • C to 3.0 • C by 2060 [33] due to the continuous increase in CO 2 emissions caused mainly by the burning of fossil fuels, deforestation, and industrial processes. In the study of Urena lobata L., the results of ecological modeling showed the extinction of the species by 2070 for the most pessimistic scenario (SSP5-8.5) [49].…”

“…The migration of forest species from the Eastern Amazon to other regions has been observed as a response to climate change, mainly due to increasing temperatures and changes in rainfall patterns [49]. These changes could lead to a decrease in water availability in some areas, affecting the survival of plants, animals, and insects that migrate and are part of the maintenance ecosystem.…”

“…In addition to the studies carried out that address bioclimatic variables with the geospatial distribution of plants, experimental studies can be conducted under controlled conditions to clarify how rising temperatures can affect the optimal conditions necessary for the growth and survival of specific plant species. Such research should include monitoring, at different temperatures, for the same species, pollen production, pollination, fruiting, growth, and mortality of plant populations, as well as the evaluation of physiological responses, such as photosynthesis and transpiration rates [49].…”

“…The deforestation registered in 2013 was responsible for a decline of 7% in estimated occurrence areas of Amazon tree species, and it will achieve a rise of 19-33% by 2050, considering the projected deforestation analyses [49]. It is recommended to adopt conservation strategies to reduce deforestation, recover degraded areas, promote the proper management of natural resources, and protect hotspots for biodiversity.…”

Studies using ecological niche models highlight the vulnerability of forest species to climate change. This work aimed to analyze the distribution of timber species Aspidosperma desmanthum, Cariniana micranta, Clarisia racemosa, Couratari oblongifolia, and Vouchysia guianensis, which are targets of deforestation, to predict the impacts of climate change and identify areas for their conservation in the Amazon. For this purpose, 37 environmental variables were used, including climatic and edaphic factors. The models were fitted using five algorithms, and their performance was evaluated by the metrics Area Under the Curve (AUC), True Skill Statistic, and Sorensen Index. The deforestation analysis was conducted using data accumulated over a period of 14 years. The study indicated that under the most pessimistic predictions, considering continued high emissions of greenhouse gases (GHGs) from the use of fossil fuels, SSP5–8.5, potential habitat loss for the studied species was more significant. Analyses of the species show that the Western Amazon has a greater climatic suitability area for the conservation of its genetic resources. Further study of the accumulated deforestation over 14 years showed a reduction in area for all species. Therefore, in situ conservation policies and deforestation reduction are recommended for the perpetuation of the analyzed forest species.

This study aimed to identify challenges in the management of conservation units through a literature review and validate them from the perspective of professionals in the field, considering the context of the Amazon Region. To achieve this, a literature review and a survey were conducted with professionals working in the field of conservation unit management. The collected data were analyzed using the Lawshe method. The results indicated that ten out of fifteen analyzed challenges were validated by the professionals. The validated challenges included: lack of financial resources, urbanization advancement, land conflicts, monitoring and enforcement, climate change, deforestation and illegal exploitation, lack of environmental education, political bureaucracy, conflicts with local communities, and corruption. The validated challenges mainly relate to management issues and the lack of more efficient governance strategies. The findings provide valuable insights for the promotion of sustainable conservation policies in the Amazon.

Astrocaryum aculeatum Mart. Moreover, Astrocaryum acaule Mart. are palm trees with ecological and extractive importance in the Amazon. These are hearty species that have been associated with archaeological sites and thrive in the presence of humans in certain areas. This work aimed to verify the effect of global climate change on the potential geographic distribution of A. acaule and A. aculeatum in the current period and future climate scenarios using ecological niche modeling in Brazilian phytogeographic domains. The modeling was based on 19 bioclimatic variables obtained from the Worldclim website and four algorithms (Climate space model, Envelope Score, Niche Mosaic, and Environmental Distance). Additionally, the Environmental Distance algorithm showed greater similarity regarding species distribution with potential occurrence in the five Brazilian domains (Amazon, Pantanal, Caatinga, Cerrado, and Atlantic Forest). The dispersion patterns were very similar between the two Astrocaryum palms though A. aculeatum was more sensitive to climatic variations. A. acaule may be more resilient to changes, as demonstrated by being able to recolonize in the southern portion of the Amazon in future scenarios in the year 2070. The modeling helped to delimit potential areas for A. aculeatum and A. acaule, indicating the need for the conservation of the species in more sensitive regions.
