“…The number of endemic species of Brazil and of the Atlantic Forest in the present study was lower than the number recorded in a study carried out in the municipality of Faria Lemos, MG (Rocha et al, 2017) and higher than that found in the Brazilian Amazon (Oliveira et al, 2017). When evaluating the EG -Ecological Group: P -Pioneer; IS -Initial Secondary; LS -Late Secondary.…”

Understanding the dynamics of endemic tree component species based on natural regeneration (NR) and adult trees (AT) is essential for formulating conservation strategies for protecting these species. The objective of the present study was to identify endemic species in a preserved area of secondary forest in the Atlantic Forest domain in Brazil and to evaluate their dynamics over 24 years. Based on inventories carried out from 1992 to 2016 of the NR (diameter at breast height - dbh ≤ 5 cm) and of the AT (dbh ≥ 5 cm) in ten sites with different characteristics (physiographic, edaphic, and successional), it was possible to, initially, identify 58 species classified as endemic to Brazil (EBR) and/or those exclusive to the Brazilian Atlantic Forest (EAF), among the 226 species in the entire survey. Subsequently, this classification was reassessed based on updated information on its occurrence, and only 38 of these species were maintained as endemic to Brazil and/or to the Atlantic Forest. Some species were recorded in the AT and NR strata, in different sites, throughout the study period, while others occurred in only one level (AT or NR), some with low abundance. Among these endemic species, eight are included in the endangered species lists, and 15 can be classified as rare, as there was only one individual in the survey. Considering the two arboreal strata it was observed that some species were abundant in the forest in all inventories and several sites, while others went throughout the study period with few individuals and, in some cases, disappeared due to mortality. These results contribute to understanding the factors that can affect the local abundance of endemic species over time, allowing the definition of conservation actions for protecting these vulnerable species, thus avoiding their extinction.

“…Among the greatest phytogeographic domains in the world, the Amazon is considered the largest tropical forest (Oliveira et al 2017), sheltering a signifi cant portion of biodiversity with different levels of richness (Vieira et al 2018). The variability of fauna and fl ora species of different taxonomic groups in this region has been lost with deforestation, a consequence of anthropic spatial occupation that is one of the most predatory forms of land use (Yanai et al 2015).…”

Scientifi c collections are important sources of information on biodiversity that can be useful for faunistic, taxonomic and phylogenetic studies. The aim of this study was to investigate the fauna of Passalidae deposited in the zoological collections in the States of the Brazilian Amazon. 14,652 Passalidae specimens are deposited in scientifi c collections, distributed in two subfamilies, 7 genera and 82 species. The species that had the highest number of deposited individuals were: Passalus interstitialis, Passalus interruptus, Veturius transversus and Paxillus leachi. Passalinae was the richest subfamily(n = 57) species, followed by Proculinae (n = 25). Passalus was the richest genus (n = 39) followed by Veturius (n = 21). The State of Amazonas was the richest (s = 67) followed by Pará (s = 45). The Instituto Nacional de Pesquisas da Amazônia was the institution with the highest number of deposited specimens. The species accumulation curve did not reach asymptote and Chao2 estimated 142 species more than the observed richness (s = 82 species). The richness of the bess beetle fauna from the Brazilian Amazon may be greater than recorded. The scientifi c collections provided quantitative and important data that allowed to determine a large fraction of the Amazon bess beetle fauna.

“…One of the strategies to reduce the pressure of forest exploitation and reduce the risk of extinction of several species is through planting in agroforestry systems, or in monoculture (OLIVEIRA et al, 2017), which allows, in addition to the production of wood with economic potential (VIEIRA et al, 2011), increase the sustainability of the sector, reducing the negative impacts that exploration causes.…”

Germination ecology of cerejeira (Amburana acreana (Ducke) A. C. Sm.) seed as a function of temperature and photoperiod

et al. 2022

The expansion of agricultural areas over the Amazon biome and illegal logging has caused a reduction in forest areas and the risk of extinction of several native species. Thus, cultivation in agroforestry or monoculture systems is essential for the economic and environmental sustainability of the sector. For this, it is necessary to understand the physiological parameters of seeds and establish protocols that help growers and nurseries during the seedling production phase. The objective of this work was to develop methods to evaluate the germination of Amburana acreana seeds at different temperatures and photoperiods. The seeds were submitted to germination tests, germination speed and average germination time at constant temperatures of 25 °C, 30 °C, 35 °C and 40 °C and two photoperiods, 12 and 24 hours of light. The temperature of 40°C inhibited germination. The germination process of A. acreana seeds is favored with a temperature of 30 °C under 24 h of light, promoting up to 100% germination.
