Potencial de pseudomonas spp. fluorescentes para biocontrole de alternaria ricini em mamoneira Potential of fluorescent pseudomonas spp. For biological control of alternaria ricini on castorbean

The potential of fluorescent Pseudomonas spp.to control Alternaria leaf spot on EHF castorbean, caused by Alternaria ricini, was studied under greenhouse conditions.Two periods for antagonist applications were tested: 48h before and simultaneously to the pathogen inoculation.Among the antagonists tested JA4 and BJ22 were the most effectives showing

Spatial modelling of Calanus finmarchicus and Calanus helgolandicus: parameter differences explain differences in biogeography

The North Atlantic copepods Calanus finmarchicus and C.helgolandicus are moving north in response to rising temperatures.Understanding the drivers of their relative geographic distributions is required in order to anticipate future changes.To explore this, we created a new spatially explicit stage-structured model of their populations throughout th
