“…The soil mesofauna extracted from soil + litterfall materials collected in the 105 sample points (1900 cm 2 , 9880 cm 3 ) totaled 619 individuals from three orders: 499 Collembola (80.6% of the soil mesofauna), 118 Acarina (19.1%) and two Diplura (<1.0%). This quantity of taxonomic groups (orders) is three to four-fold lower than that reported by Santos et al (2017) (9 orders) and Almeida, Souto, and Souto (2013) (13 orders), respectively, for a remnant of caatinga vegetation in Santana do Ipanema, AL, Brazil, and a 30-year-old preserved caatinga forest in Barra de Santa Rosa, PB, Brazil. These data indicate that the soil mesofauna order diversity was negatively and strongly affected by the removal of forest cover and overgrazing.…”

Environmental degradation impacts negatively the diversity and quantity of invertebrates living in the soil, mainly in semiarid regions. Generally, a high diversity of invertebrates indicates good biofunctionality and sustainable use of the soil. We evaluated the effects of 14 years of grazing deferment and the presence of the native trees Mimosa tenuiflora and Cnidoscolus quercifolius on the soil mesofauna of a degraded Caatinga area, according to the χ 2 test, applied to assess the abundance of these microorganisms. The grazing deferment alone more than tripled the soil mesofauna. The abundance of the mesofauna under M. tenuiflora canopies increased by a factor of 3.17 and 3.41 in grazed and ungrazed areas, respectively, and under C. quercifolius canopies increased by a factor of 22.6 in the ungrazed area. The effect of M. tenuiflora in the grazed area was similar to 14 years of grazing deferment. The quantity of mesofauna under C. quercifolius canopies after 14 years of grazing deferment was 6.6-fold higher than that under M. tenuiflora canopies, under similar conditions. The grazing deferment and trees, especially C. quercifolius, increased the soil mesofauna; however, full recovery of such organisms in degraded Caatinga areas may need more than 14 years. Considering the current scenario of increasing environmental degradation, our findings regarding the relationships between soil mesofauna, grazing deferment and native trees are important to devise strategies and procedures for the recovery of degraded areas in the Caatinga biome.

“…O estabelecimento do preço é uma ação muito importante para garantir o bom funcionamento das micro e pequenas empresas. No entanto, determinar o preço de produtos ou serviços não é uma atividade simples, pois é essencial que todos os custos relativos a esses produtos ou serviços oferecidos sejam apurados (SANTOS, 2020).…”

Faced with the current reality, in wich there is a large number of individual micro-enterprises involved, the need for structuring this type of business emerges, as it is also seen, at the same time, a high number of closures of these companies due to failures in cost management and in the revenue generation, which are directly influenced by the selling price of the products offered. In this context, the objective of this work is to analyze the selling prices touched by an individual micro-entrepreneur in the food industry, with the purpose of proposing appropriate selling prices for her business. This study is characterized as applied research, with a qualitative and quantitative approach to the problem, its objective is described as descriptive and the technical procedures as a case study. The research involved a survey of the items that make up the sale price and the application of tools relevant to cost management, such as the contribution margin and the break-even point that can effectively contribute to sales strategies and, consequently, to an increase in revenue and markup for product pricing. Finally, the products that generate the highest therapeutic returns and new sales price standards for all products were identified, according to the analyzed analyses, with these suggested values being higher than those already transmitted. It is noteworthy that this work seeks to clarify the individual microentrepreneur about the importance of managing their costs and how to start this practice, which directly contributes to the development of their business.

“…Ao passo que o uso de fertilizantes amoniacais e práticas que degradam e expõem o solo contribuem drasticamente para a perda da maior parte da mesofaúna no solo (Primavesi, 2002), considerados indicadores de qualidade do solo (Silva et al, 2019). Assim, a avaliação da comunidade do solo, como bioindicadores, tem se mostrado eficiente nas comparações de diferentes condições ambientais (Santos et al, 2017).…”

O uso intenso e/ou inadequado dos solos acarreta perda dos atributos químicos necessários para manutenção da produção agropecuária. A fertilidade do solo é apenas um entre vários fatores que determinam a magnitude do rendimento das culturas, e interfere grandemente na produtividade agrícola. Nesse contexto, objetivou-se avaliar o os efeitos nas propriedades químicas do solo frente a dois tipos de manejo com e sem métodos agroecológicos. O solo 1 recebeu manejo agroecológico (irrigação, adubação orgânica, capina, cobertura morta) e o solo 2 foi recebeu apenas gradagem e capina manual. Foram analisados o pH, as quantidades de P, K+, Ca+2, Mg+2, Na+, Al+3, H++Al+3, COT, MO, CTC, SB, V (%) e m (%) no período de agosto à setembro de 2016. O delineamento experimental utilizado foi o DBC com o fatorial 4 x 2 com 10 repetições. 4 níveis de profundidade (0-5, 5-10, 10-15 e 15-20 cm) x 2 tipos de solo. O manejo empregado no solo 1 condiciona valores de pH, CTC, SB, V (%), K2+, Ca2+, superiores ao solo 2, juntamente com Na+. 2. Ambos os solos apresentaram teores similares de Mg2+ embora a SB e V (%) seja maiores para o solo 1. 3. Os valores de Al3+, H++Al3+, m (%) foram maiores no solo 2, do mesmo a MO e o COT se encontra em nível superior.
