Oil palm seed distribution [PDF]

open access: yesOléagineux, Corps gras, Lipides, 2005
For a tropical plant, the oil palm commodity chain has the peculiarity of possessing a major seed production sector for reasons that are primarily genetic. This seed sector has numerous original aspects. Breeders are also propagators and usually also distribute their seeds. Oil palm seeds are semi-recalcitrant: they display pseudo-dormancy.

Copepod manipulation of oil droplet size distribution [PDF]

open access: yesScientific Reports, 2019
AbstractOil spills are one of the most dangerous sources of pollution in aquatic ecosystems. Owing to their pivotal position in the food web, pelagic copepods can provide crucial intermediary transferring oil between trophic levels. In this study we show that the calanoidParacartia granican actively modify the size-spectrum of oil droplets.

Are benefits from oil - stocks diversification gone? New evidence from a dynamic copula and high frequency data [PDF]

open access: yes, 2015
Oil is perceived as a good diversification tool for stock markets. To fully understand this potential, we propose a new empirical methodology that combines generalized autoregressive score copula functions with high frequency data and allows us to ...
