Phytoplankton require light for photosynthesis. Yet, most phytoplankton species are heavier than water and therefore sink. How can these sinking species persist? Somehow, the answer should lie in theâ€¦ (More)

Mathematical models predict that species interactions such as competition and predation can generate chaos. However, experimental demonstrations of chaos in ecology are scarce, and have been limitedâ€¦ (More)

Intertidal sediments usually contain a high amount of dimethylsulfoniopropionate (DMSP) and therefore represent environments with a potentially high emission of dimethylsulfide (DMS). However,â€¦ (More)

We show that there is a large class of nonspecial effective divisors of relatively small degree on real algebraic curves having many real components i.e. on M -curves. We apply to 1. complete linearâ€¦ (More)

A real hyperelliptic curve X is said to be Gaussian if there is an automorphism Î± : XC â†’ XC such that Î± = [âˆ’1]C â—¦ Î±, where [âˆ’1] denotes the hyperelliptic involution on X. Gaussian curves ariseâ€¦ (More)

We analyze the predictions of a reaction advection di usion model to pinpoint the nec essary conditions for bloom development of sinking phytoplankton species in strati ed waters This reveals thatâ€¦ (More)

Irigoien et al. reply - We agree with Dolan's concern that simple morphological traits reveal only part of the zooplankton biodiversity. We argue, however, that this is unlikely to affect ourâ€¦ (More)
