Genomic Selection (GS) has been studied in several crops with potential to increase the rates of genetic gain and reduce the length of breeding cycle. Despite the relevance, there is a modest number of reports applied to the genus Coffea. Nevertheless, the effective implementation depends on the ability to consider genomic models that represent with adequate reliability the breeding scenario in which the specie are inserted. Coffee experimentation, in general, is represented for evaluations in multiples sites and harvests (MET), in order to understand the interaction magnitude and predicting the performance of untested genotypes. Therefore, the main objective of this study was investigate GS models that accommodate MET modeling. A expansion of the traditional GBLUP was proposed in order to accommodate the interactions in the GS model. Different scenarios that mimic the coffee breeding and models commonly used in the analysis were compared. In terms of goodness of fit this approach showed the lowest AIC and BIC values and, consequently, the best goodness of fit. The predictive capacity was measured by cross-validation and, in contrast with the GBLUP, the incorporation of the MET modeling showed higher predictive accuracy (on average 10-17% higher) and lower prediction errors. All the genomic analysis were performed using the Genotyping-by-sequencing (GBS) approach, which showed a good potential to be used in coffee breeding programs. Thus, as conclusion, the results achieved may be used as basis for additional studies into the Genus Coffea and expanded for other perennial crops, that have a similar experimentation design.

We investigated ecological patterns of richness and abundance of Anastrepha fruit flies, based on a long-term series with a dataset from 1998 to 2010, subdivided into four subseries describing pest management through the systems approach (integration of different measures, at least two of which act independently, with cumulative effects), and its impact on abundance and diversity of fruit flies. Richness and abundance were influenced by time and distance but to different extents. Spatio-temporal analysis taking into account the implementation of the systems approach revealed
clear effects of the pest management on fruit fly richness and abundance. However, abundance was affected by the systems approach three years before richness was. Abundance and richness also showed different relationships with time and distance between orchards and forest. The Gompertz
model, used to describe the relationship between area and species richness, was the function that showed the best fit to the data. The richness-partitioning analysis, which decomposes beta diversity, indicated different distributions of richness values and predictions for additive partitioning that were directly associated with the implementation of the systems approach. The spectral analysis projected different trends for peaks, indicating that the systems approach is able to delay the time for new population peaks of fruit flies. |
