Identifiability of linear stochastic state-space models with application to ecology
Frederic Barraquand, Julien Gibaud
State-space models are dynamical systems defined by a latent and an observed process. In ecology, stochastic state-space models in discrete time are most often used to describe the…
Local intraspecific aggregation in phytoplankton model communities: spatial scales of occurrence and implications for coexistence
Coralie Picoche, William R. Young, Frédéric Barraquand
The coexistence of multiple phytoplankton species despite their reliance on similar resources is often explained with mean-field models assuming mixed populations. In reality, obse…
No sensitivity to functional forms in the Rosenzweig-MacArthur model with strong environmental stochasticity
Frédéric Barraquand
The classic Rosenzweig-MacArthur predator-prey model has been shown to exhibit, like other coupled nonlinear ordinary differential equations (ODEs) from ecology, worrying sensitivi…
The evidence contained in the P-value is context dependent
Florian Hartig, Frédéric Barraquand
In a recent opinion article, Muff et al. recapitulate well-known objections to the Neyman-Pearson Null-Hypothesis Significance Testing (NHST) framework and call for reforming our p…
The Traill island model for lemming dynamics, how it compares to Fennoscandian vole dynamics models, and a proposed simplification
Frédéric Barraquand, John-André Henden, Olivier Gilg +2
The Traill island model of Gilg et al. (2003) is a landmark attempt at mechanistic modelling of the cyclic population dynamics of rodents, focusing on a high Arctic community. It m…
Effects of stage structure on coexistence: mixed benefits
Gaël Bardon, Frédéric Barraquand
The properties of competition models where all individuals are identical are relatively well-understood; however, juveniles and adults can experience or generate competition differ…
Seed banks can help to maintain the diversity of interacting phytoplankton species
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. At th…
The effect of seasonal strength and abruptness on predator-prey dynamics
Alix M. C. Sauve, Rachel A. Taylor, Frédéric Barraquand
Coupled dynamical systems in ecology are known to respond to the seasonal forcing of their parameters with multiple dynamical behaviours, ranging from seasonal cycles to chaos. Sea…
Inferring species interactions using Granger causality and convergent cross mapping
Frederic Barraquand, Coralie Picoche, Matteo Detto +1
Identifying directed interactions between species from time series of their population densities has many uses in ecology. This key statistical task is equivalent to causal time se…
How self-regulation, the storage effect and their interaction contribute to coexistence in stochastic and seasonal environments
Coralie Picoche, Frederic Barraquand
Explaining coexistence in species-rich communities of primary producers remains a challenge for ecologists because of their likely competition for shared resources. Following Hutch…
Fitting stochastic predator-prey models using both population density and kill rate data
Frederic Barraquand, Olivier Gimenez
Most mechanistic predator-prey modelling has involved either parameterization from process rate data or inverse modelling. Here, we take a median road: we aim at identifying the po…
Indirect effects of primary prey population dynamics on alternative prey
Frederic Barraquand, Leslie F. New, Stephen Redpath +1
We develop a theory of generalist predation showing how alternative prey species are affected by changes in both mean abundance and variability (coefficient of variation) of their…
