“…The greater ecological dominance of Joannesia princeps and Spondias venulosa (which showed large size and higher density of individuals in most treatments), is in line with the results observed by França and Stehmann (2013), who also highlight Joannesia princeps in primary and secondary forests of the Atlantic Forest. In this sense, as presented by Doust et al (2006) and Tunjai and Elliott (2012), characteristics such as seed size can influence the germination process and establishment of plant species used (larger seeds generally have greater germination potential).…”

This study was carried out at the Vale Natural Reserve in Linhares, Espírito Santo, Brazil, with the objective of testing the use of direct seeding as a forest restoration method in Tabuleiro Forest (also called Tableland Forest outside of Brazil) 16 years after its implantation. Three different treatments were evaluated in which 29 native species with different area preparations were used, namely: Total manual mowing + residue burning + herbicide (T1); Total manual mowing + residue burning (T2); and Total manual mowing (T3). Each treatment had an area of 100m² (10x10m) and an interval between plots of 2 m. The survival of the individuals implanted in the direct seeding was evaluated, as well as the natural regeneration of the new individuals with Diameter at Breast Height (DBH) = 15 cm. As a result, after 16 years we can see the presence of 16 species and 106 individuals, as well as a Shannon’s diversity index of (H’) = 1.917 and Pielou’s index (P) = 0.691, demonstrating a low floristic diversity in the area. The species which stood out the most (most individuals) were: Joannesia princeps Vell. L.C.; Spondias venulosa (Engl.) Engl.; and Peltophorum dubium (Spreng.) Taub. As a suggestion, it is recommended to use direct seeding in a complementary manner to other restoration techniques, and there should be monitoring of the area in order to assess the evolution of the process and the need for any interventions to assertively assist the entire process.

“…A floristic inventory was performed from fertile specimens collected in preserved fragments in the Rio Doce State Park located in the Doce River basin. Species identification was done by comparing the material from BHCB Herbarium from the Federal University of Minas Gerais as described by França and Stehmann (2013). Another floristic survey was undertaken in an impacted riparian area of Gualaxo River located at Paracatú de Baixo (Fig.…”

Understanding the Environmental Impact of a Mine Dam Rupture in Brazil: Prospects for Remediation

et al. 2019

The rupture of the Fundão mine dam in Mariana municipality, Minas Gerais State, Brazil, spilled the tailings across the Doce River basin. These tailings, composed of residues discarded from the beneficiation of iron ore, are rich in SiO 2 and Al 2 O 3 , as well as some ether amine compounds and NaOH. The aim of this study was to assess the distribution of these sediments, as well as their effect on the riparian zones reached, as compared with preserved sites. Sediment deposition in the river resulted in a morphological change from a meandering profile to a braided aspect. The nutrient and mineral content (P, K, Ca, Mg, Cu, Fe, Mn, Zn, and NO 3 − ) and soil organic matter of the sediments were depleted, whereas NH 4 + , Na, and pH increased. A random presence of ether amines in the sediments was confirmed by quantitative and chromatographic analyses, with concentrations ranging from 0 to 57.8 mg kg −1 ; Na reached values as high as 150 mg kg −1 . The impact of the dam tailings on biota was assessed by estimating total microbial biomass (phospholipid fatty acids), which were depleted in sediments relative to soils from preserved sites. Overall plant mortality, as well as a low resilience capacity, were also observed. Ether amines and Na present in the sediments had a strong toxic effect in the environment. Identification of these substances as the main impact factors will help guide future remediation efforts.

“…The palynomorphs encompass five distinct vegetation structures (i.e., swamp, Cerrado, Atlantic Forest, gallery forest, and altitudinal forest) that experienced continuous historical changes from fluvial to lake ecosystems (Fonseca‐Silva et al, 2019). The native Atlantic Forest in this region is mainly composed of typical families of seasonal semideciduous forests, with the predominance of Fabaceae, Myrtaceae, Lauraceae, and Rubiaceae species (França & Stehmann, 2013). The region contains approximately 300 lakes, of which 42 are within the Park limits (Latini & Petrere, 2004; Maillard et al., 2012).…”

Forest–lake ecotones in a tropical forest: Terrestrial invertebrate inputs to lakes decrease with forest distance

et al. 2022

View full text Add to dashboard Cite

Ecotones between tropical forests and lakes compose an ecosystem interconnection with a high abundance of terrestrial invertebrates, which represent an outstanding resource for the aquatic fauna. However, there is still little quantitative information on tropical forest contribution in terms of invertebrate inputs into lacustrine systems and the factors controlling this flux. To quantify the terrestrial invertebrate contribution into tropical lakes, we selected six lakes located in the Atlantic rainforest, south‐eastern Brazil, and used pan traps placed in the lakeshore. We focused on total abundance, biomass, and richness of insect orders. To assess the influence of forest and lake morphometry on terrestrial invertebrate inputs into lakes, we measured the forest–lake distance and considered the morphometric characteristics of each lake. Distance from forest negatively affected the invertebrate biomass reaching the lakes. The dissimilarity across different ecotones also increased with distance from the forest. Perimeter‐to‐area ratio negatively affected the invertebrate abundance, suggesting that more dendritic lakes receive more invertebrates from the forest. We estimated that annually, on average 21 tons of terrestrial invertebrates fall into the studied lakes, representing a massive food resource for the aquatic ecosystem. Hence, if the distance from the forest increases due, for instance, to severe drought or deforestation, it will create an herbaceous environment unable to provide such a quantity of insects to the water ecosystems, compromising aquatic and terrestrial trophic webs dynamics.
