After the grinding stage of yam tubers, ultrasonic treatment (UT) is comparedto traditional starch extraction. Different sonication conditions of amplitude(12, 40, and 68%) and time (3, 6, and 9 min) are evaluated along two othertreatments: a control (0% amplitude) and 70% amplitude for 15 min, in order tocompare the traditional extraction method and extreme ultrasonic conditions.Extraction yield, centesimal composition, color instrumental analysis, scanningelectron microscopy, optical microscopy, particle size, x-ray diffraction, swellingpower and solubility, paste clarity, pasting properties, thermal properties, andabsolute density are used to evaluate the isolated starches. Yield increased from29.85% (control) to 32.09% (70% amplitude, 15 min). The surface of certainsonicated treated starch becomes damaged, also amorphous region is reduced,but no change in the crystalline pattern of starch is observed, characterized as Btype. Except for treated starches at 70% amplitude for 15 min, all others showedno change or slight increase of peak viscosity. Despite the increase in yield,ultrasound caused changes on physical and chemical characteristics, dependingon time and amplitude, hence it may be used as alternative technique forphysical starch modification, for example, for producing thickeners agent. |

In Brazil, the country with the highest plant species richness in the world, biodiverse savannas and grasslands ? i.e., grassy ecosystems, which occupy 27% of the country ? have historically been neglected in conservation and scientific treatments. Reasons for this neglect include misconceptions about the characteristics and dynamics of these ecosystems, as well as inconsistent or regionally restricted terminology that impeded a more adequate communication about Brazil's savannas and grasslands, both within the country and internationally. Toward improved communication and recognition of Brazil?s diversity of ecosystems, we present the key drivers that control the main types of grassy ecosystems across Brazil (including in regions of the country where forests dominate). In doing so, we synthesize the main features of each grassy ecosystem in terms of physiognomy and ecological dynamics (e.g., relationships with herbivores and fire). We propose a terminology both for major grassland regions and for regionally relevant vegetation physiognomies. We also discuss terms associated with human land management and restoration of grassy ecosystems. Finally, we suggest key research needs to advance our understanding of the ecology and conservation values of Brazil?s grassy ecosystems. We expect that a common and shared terminology and understanding, as proposed here, will stimulate more integrative research that will be fundamental to developing improved conservation and restoration strategies.
