“…The Cerrado biome in central Brazil covers about 2 million km 2 . It represents a diverse ecosystem, harboring 4800 endemic plant and vertebrate species (Strassburg et al , 2017), and, as most of the Brazilian basins originate in central Brazil, is an important source of freshwater (Lima et al , 2011). However, despite its high biodiversity and socioeconomic importance, the destruction of this ecosystem is continuing at an accelerated rate (Vieira et al , 2022).…”

A paleoecologic analysis of pollen, macrocharcoal and trace elements from a lacustrine sediment core located at Lake Feia, central Cerrado (Goiás State, Brazil), was used to evaluate the relationship between vegetation, fire and climate during the Holocene. The development of cerrado vegetation appears to have begun 6000 years ago, initially with the establishment of an open cerrado, followed from 4800 cal a bp by a change to a woody cerrado driven by an increase in summer insolation. The increases in precipitation levels in the central Cerrado during the last 5000 years are related to the increased influence of the Amazon in central Brazil, which has facilitated biomass burning and anthropogenic activities in the region of Lake Feia. Multi‐centennial‐scale changes in water level‐related and gallery forest pollen assemblages indicate three main dry episodes, at 3440–2760, 2700–1690 and 1330–1150 cal a bp, linked to regional shifts between northern and southern South American summer monsoon boundaries. The presence of low continuous fire activity does not appear to have affected vegetation recovery, whereas two intervals with increased fire activity, at ~3300 and ~1300 cal a bp, indicated a slower recovery.

“…After the mesocarp is extracted, pulverized and resuspended in water, it can be used as a food supplement (Silva et al, 2019). Several studies also report its use in the treatment of infectious diseases, due to its proven anti-inflammatory and analgesic properties, being indicated as a healing agent (Batista et al, 2006), in the treatment of menstrual pain (Sudre et al, 2015), antitumor (Rennó et al, 2008), antithrombotic (De Lima et al, 2020), antimicrobial (Barroqueiro et al, 2016) and in the treatment of rheumatic diseases (Azevedo et al, 2007).…”

The objective was to characterize the physical-chemical, thermal and mechanical properties of a polymer blend based on babassu coconut mesocarp starch, with the addition of glycerin, melamine/formaldehyde. The babassu coconut mesocarp was used as raw material and the plasticizers glycerin, melamine/formaldehyde were added. Thermogravimetric analysis (TGA), Differential Scanning Calorimetry (DSC), Fourier Transform Infrared (FTIR), Visible Ultraviolet (UV-Vis), X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM) and traction. The polymer blend showed non-homogeneous distribution with irregular and rough undulations, small differences in color and melamine concentrates, presence of starch residues, without pores and fissures. TGA revealed that the degradation ranges of starch and most organic compounds ranged from 210 ºC to 400 ºC. The DSC showed a predominance of endothermic events. The FTIR identified the starch present and the peaks of melamine and glycerin compounds. UV-Vis showed maximum lengths between 220 and 247 nm, and an accentuated shoulder at 281 nm referring to the electronic transitions of the double bonds present in melamine and starch. The blend is amorphous, with points of crystallinity due to starch and/or overlapping with melamine. The tensile mechanical behavior was of the ductile type. It is concluded that the proposed methodology for the formation of a polymer blend based on babassu coconut mesocarp starch showed good results for physical-chemical, mechanical and thermal properties, being an innovative product with possible potential for different applications.

With the crisis and the increase of agricultural pests, there was the need for evolution in the correct management of insects in major crops. Biological control provides for the use of natural inputs as toxicological agents against existing enemies in organic farming. In this way, the use of botanical insecticides regulates the natural balance of species. In order to obtain new methods of control and management, essential oils were used to eliminate aphids present in cabbage specimens, thus allowing the continuity of vegetable productions away from pests. In this study, we will be able to evaluate the viability of different vegetable oils as a natural insecticide on aphids of cabbage. It is concluded that, the mortality rate showed its 100% efficiency on aphids, among the concentrations of 10%, 25%, 50% and 100%, in different oils tested. According to what was observed, the mortality time showed that Mauritia flexuosa obtained the shortest time as being the best to kill the aphids, followed by the other oils. It is worth noting that for use on leaf specimens only the concentrations 10%, 25%, regardless of the oils offered no commercial damage.
