Towards a set of agrosystem-specific cropland mapping methods to address the global cropland diversity por Waldner, François, De Abelleyra, Diego, Veron, Santiago Ramón, Zhang, Miao, Wu, Bingfang, Plotnikov, Dmitry, Bartalev, Sergey, Lavreniuk, Mykola, Skakun, Sergii, Kussul, Nataliia, Le Maire, Guerric, Dupuy, Stéphane, Jarvis, Ian, Defourny, Pierre

“…The robustness of the accuracy with respect to a reduction of the quantity of calibration data available was also assessed by a bootstrap approach in which the amount of training data was systematically reduced. Methods reached overall accuracies ranging from 85% to 95%, which demonstrates the ability of 250 m imagery to resolve fields down to 20 ha. …”

Cell size regulation and proliferation fluctuations in single-cell derived colonies por Nieto, César, Vargas García, César, Pedraza, Juan Manuel, Singh, Abhyudai

“…In contrast, in classical size-independent proliferation models, where cell division occurs based on a pure timing mechanism, fluctuations in cell number increase monotonically over time to approach a nonzero value. We systematically study these differences and the convergence speed using different size control strategies.…”

Genomic resources to guide improvement of the shea tree por Hale, I., Ma, X., Melo, A.T.O., Padi, Francis K, Hendre, P.S., Kingan, S.B., Sullivan, S.T., Chen, S., Boffa, J.-M., Muchugi, Alice, Danquah, A., Barnor, M.T., Jamnadass, Ramni H., Peer, Y. van de, Deynze, A. van

“…Despite its economic and cultural value, however, not to mention the ecological roles it plays as a dominant parkland species, shea remains semi-domesticated with virtually no history of systematic genetic improvement. In truth, shea’s extended juvenile period makes traditional breeding approaches untenable; but the opportunity for genome-assisted breeding is immense, provided the foundational resources are available. …”
