Local intraspecific aggregation in phytoplankton model communities: spatial scales of occurrence and implications for coexistence

1 code implementation • 20 Oct 2022 • Coralie Picoche, William R. Young, Frédéric Barraquand

Local spatial aggregation can hinder competitive exclusion since individuals then interact mostly with other individuals of their own species, rather than competitors from different species.

Seed banks can help to maintain the diversity of interacting phytoplankton species

1 code implementation • 22 Mar 2021 • Coralie Picoche, Frédéric Barraquand

Seed formation is part of the reproductive cycle, leading to the accumulation of resistance stages that can withstand harsh environmental conditions for long periods of time.

Inferring species interactions using Granger causality and convergent cross mapping

1 code implementation • 2 Sep 2019 • Frederic Barraquand, Coralie Picoche, Matteo Detto, Florian Hartig

Our results therefore imply that Granger causality, even in its linear MAR($p$) formulation, is a valid method for inferring interactions in nonlinear ecological networks; using GC or CCM (or both) can instead be decided based on the aims and specifics of the analysis.
