O objetivo do estudo foi analisar a predição da distribuição de espécies florestais madeireiras, em escala local, utilizando dados de ocorrência agrupados por classe diamétrica. Para estimar a distribuição foi utilizado o método de máxima entropia (Maxent) e as ocorrências são de inventário florestal de planos de manejo. Foram selecionadas seis variáveis preditoras, por espécie, pelo método de todas as regressões possíveis. Os modelos tiveram em média bom desempenho (AUC = 0,7; taxa de omissão = 8,8%), demonstrando a viabilidade de se predizer a distribuição de espécies por classe diamétrica. De acordo com os modelos, Astonium lecointei, Clarisia racemosa e Ceiba pentandra com diâmetro a altura do peito (DAP) ≥ 100 cm têm maior probabilidade de ocorrer em locais com altitudes mais elevadas do terreno. Esse procedimento de modelagem é eficiente para ampliar o conhecimento sobre as preferências de habitat e a distribuição geográfica de espécies na paisagem. The aim of the study was to analyze the predicting the distribution of forest tree species, on a local scale, using occurrence data grouped by diameter class. To estimate the distribution of species was used the maximum entropy method (Maxent) and the occurrence data are forest management plan. Six predictor variables were selected by species by method of all possible regressions. The models, by species and diameter class, had an average good performance (AUC = 0.7; omission rate = 8.8%), demonstrate the viability of predicting distribution of species by diameter class. According to the models, trees Astonium lecointei, Clarisia racemosa and Ceiba pentandra with diameter at breast height (DBH) ≥ 100 cm are more likely to occur in localized at higher elevations. This modeling procedure is efficient to increase knowledge about habitat preferences and geographical distribution of species in the landscape.

Artificial hybridization plays a fundamental role in plant breeding programs since it generates new genotypic combinations that can result in desirable phenotypes. Depending on the species and mode of reproduction, controlled crosses may be challenging, and contaminating individuals can be introduced accidentally. In this context, the identification of such contaminants is important to avoid compromising further selection cycles, as well as genetic and genomic studies. The main objective of this work was to propose an automated multivariate methodology for the detection and classification of putative contaminants, including apomictic clones (ACs), self-fertilized individuals, half-siblings (HSs), and full contaminants (FCs), in biparental polyploid progenies of tropical forage grasses. We established a pipeline to identify contaminants in genotyping-by-sequencing (GBS) data encoded as allele dosages of single nucleotide polymorphism (SNP) markers by integrating principal component analysis (PCA), genotypic analysis (GA) measures based on Mendelian segregation, and clustering analysis (CA). The combination of these methods allowed for the correct identification of all contaminants in all simulated progenies and the detection of putative contaminants in three real progenies of tropical forage grasses, providing an easy and promising methodology for the identification of contaminants in biparental progenies of tetraploid and hexaploid species. The proposed pipeline was made available through the polyCID Shiny app and can be easily coupled with traditional genetic approaches, such as linkage map construction, thereby increasing the efficiency of breeding programs.
