Abstract: The aim of this study was to explore spatial patterns of genetic structure in sheep breeds sampled in Brazil using Single Nucleotide Polymorphisms (SNPs) in order to evaluate whether or not the genetic and geographic dis-tances are interrelated in this species. Samples genotyped using the 50KSheepSNPChip (Illumina) included 215 animals from eight different sheep breeds. All collection sites were georeferenced and data analyzed to determine geographic patterns from genetic data. To evaluate the correlation between genetic and geographic distances Mantel tests, Allelic Aggregation Index Analyses (AAIA), and spatial autocorrelation were performed. Genetic Landscape Shape procedure and Monmonier?s Algorithm were used to generate graphical visualization of the genetic distances across the landscape. The observed correlation observed between genetic and geographical distances was 0.552 (P <0.00099). Observed AAIA results (Rave =0.16, P <0.001) indicated a non-random distribution of genotypes across the landscape. High genetic differentiation was observed in the Southern re-gions of Brazil, separating wool and hair sheep. Low genetic distances were observed between flocks and breeds from north and center-west regions, and may be the result of unrecorded introgressions resulting from past unknown crossbreeding events. Observed Spatial Autocorrelation Analyses results indicate a minimum distance of 400 km should be used between collection sites to maximize genetic variability in future germplasm samplings for conservation of genetic resources.

Abstract: Studies of the successive application of manure as fertilizer and its combined effect with long-term soil management systems are important to the identification of the interdependence of physical attributes. The aim of this study was to evaluate changes in the physical properties of a Rhodic Kandiudox under management systems employing successive applications of pig slurry and poultry litter, and select physical indicators that distinguish these systems using canonical discriminant analysis (CDA). The systems consisting of treatments including land use, management and the application time of organic fertilizers are described as follows: silage maize under no-tillage (NT-M7 years); silage maize under conventional tillage (CT-M20 years); annual pasture with chisel plowing (CP-P3 years); annual pasture with chisel plowing (CP-P15 years); perennial pasture without tillage (NT-PP20 years); and no-tillage yerba mate (NT-YM20 years) and were compared with native forest (NF) and native pasture (NP). Soil samples were collected from the layers at the following depths: 0.0-0.05, 0.05-0.10, and 0.10-0.20 m, and were analyzed for bulk density, porosity, aggregation, flocculation, penetration resistance, water availability and total clay content. Canonical discriminant analysis was an important tool in the study of physical indicators of soil quality. Organic fertilization, along with soil management, influences soil structure and its porosity. Total porosity was the most important physical property in the distinction of areas with management systems and application times of manure for the 0.0-0.05 and 0.10-0.20 m layers. Soil aeration and micropores differentiated areas in the 0.05-0.10 m layer. Animal trampling and machinery traffic were the main factors inducing compaction of this clayey soil. Resumo: Estudos da aplicação sucessiva de esterco como fertilizante e seu efeito combinado com sistemas de manejo do solo a longo prazo são importantes para a identificação da interdependência de atributos físicos. O objetivo deste estudo foi avaliar as mudanças nas propriedades físicas de um sistema Rhodic Kandiudox sob manejo empregando aplicações sucessivas de dejetos de suínos e de cama de frango, e selecionar indicadores físicos que distinguem esses sistemas usando análise discriminante canônica (CDA). Os sistemas que consistem em tratamentos, incluindo o uso da terra, manejo e o tempo de aplicação dos fertilizantes orgânicos são descritos a seguir: silagem de milho sob plantio direto (NT-M7 anos); silagem de milho sob preparo convencional (CT-M20 anos); pastagem anual com armação de cinzel (CP-P3 anos); pastagem anual com cinzeladura (CP-P15 anos); pastagem perene sem plantio direto (NT-PP20 anos); e erva-mate de plantio direto (NT-YM20 anos) e foram comparados com floresta nativa (NF) e pastagem nativa (PN). Amostras de solo foram coletadas nas seguintes profundidades: 0,0-0,05, 0,05-0,10 e 0,10-0,20 me analisadas quanto à densidade do solo, porosidade, agregação, floculação, resistência à penetração, disponibilidade de água e teor de argila total. A análise discriminante canônica foi uma importante ferramenta no estudo de indicadores físicos de qualidade do solo. A adubação orgânica, juntamente com o manejo do solo, influencia a estrutura do solo e sua porosidade. A porosidade total foi a propriedade física mais importante na distinção de áreas com sistemas de manejo e tempos de aplicação de esterco para as camadas de 0,0-0,05 e 0,10-0,20 m. Aeração do solo e áreas diferenciadas com microporos na camada de 0,05-0,10 m. O pisoteio animal e o tráfego de máquinas foram os principais fatores que induziram a compactação deste solo argiloso.
