Ecology and Evolution, 2020 Recent studies have demonstrated the great advantages of marine reserves in solving bycatch problems by maintaining the persistence (i.e., avoid extinction) of endangered species without sacrificing the fisheries yields of target species.

Invasion and effective size of graph-structured populations. [PDF]
PLoS Computational Biology, 2018 Population structure can strongly affect evolutionary dynamics. The most general way to describe population structures are graphs. An important observable on evolutionary graphs is the probability that a novel mutation spreads through the entire ...

Abstraction of Markov Population Dynamics via Generative Adversarial Nets
, 2021 Markov Population Models are a widespread formalism used to model the dynamics of complex systems, with applications in Systems Biology and many other fields. The associated Markov stochastic process in continuous time is often analyzed by simulation, which can be costly for large or stiff systems, particularly when a massive number of simulations has ...

New Zealand regions, 1986-2001: Population dynamics [PDF]
, 2005 New Zealand regions have markedly different population dynamics. Population change in a region is driven by three different factors: fertility, mortality and migration.

Chimera dynamics of generalized Kuramoto–Sakaguchi oscillators in two-population networks
Journal of Physics A: Mathematical and Theoretical, 2023 Abstract Chimera dynamics, an intriguing phenomenon of coupled oscillators, is characterized by the coexistence of coherence and incoherence, arising from a symmetry-breaking mechanism. Extensive research has been performed in various systems, focusing on a system of Kuramoto–Sakaguchi (KS) phase oscillators.

Non-linear analysis indicates chaotic dynamics and reduced resilience in model-based Daphnia populations exposed to environmental stress. [PDF]
PLoS ONE, 2014 In this study we present evidence that anthropogenic stressors can reduce the resilience of age-structured populations. Enhancement of disturbance in a model-based Daphnia population lead to a repression of chaotic population dynamics at the same time ...

Embedding population dynamics in mark-recapture models [PDF]
, 2009 Mark-recapture methods use repeated captures of individually identifiable animals to provide estimates of properties of populations. Different models allow estimates to be obtained for population size and rates of processes governing population dynamics.
