Detection and decay rates of prey and prey symbionts in the gut of a predator through metagenomics. Author(s): PAULA, D. P.; LINARD, B.; ANDOW, D. A.; SUJII, E. R.; PIRES, C. S. S.; VOGLER, A. P. DNA methods are useful to identify ingested prey items from the gut of predators, but reliable detection is hampered by low amounts of degraded DNA. PCR-based methods can retrieve minute amounts of st... ... Repository: BDPA Publication year: 2015
Short-term retrieval of water transparency from a caged-fish farm using Landsat-8/OLI images. Author(s): GOMES, A. C. C.; PENTEAN, R.; PORTINHO, J. L.; VICENTE, L. E.; ARAUJO, L. S. de; MANZATTO, C. V.; ALCÂNTARA, E. Abstract: The intense growth of fish farming in Brazil requires an operational monitoring of water quality.

Modeling enteric methane emission from beef cattle in Brazil: a proposed equation performed by principal component analysis and mixed modeling multiple regression. Author(s): MEDEIROS, S. R. de; BARIONI, L. G.; BERNDT, A.; FREUA, M. C.; ALBERTINI, T. Z.; COSTA JUNIOR, C.; FELTRIN, G. B. Brazil has the largest commercial beef cattle herd in the world but does not have its own model to predict methane (CH4 ) emission. The aim of this study was to create the first empirical enteric CH4... ... Repository: BDPA Publication year: 2014
