Research Graph
This page is generated from the same canonical sources that drive the rest of the website. It is a relationship layer rather than a second catalogue: domain metadata remain authoritative in Publications, Talks, Software, Teaching, Posts, and Research.
Public graph: canonical public mirrors and curated registries only. Private repository metadata is excluded before serialization.
Environmental variability and pressure-state relationships
Research question: How do climate and oceanographic variability, natural forcing, fishing pressure, and their interactions alter productivity and the state of pelagic populations? Why it matters: Eastern Boundary Upwelling Systems are highly variable, so separating environmental forcing from fishing effects is essential for detecting pressure-state relationships, thresholds, and regime changes.

Fisheries dynamics and adaptive management
Research question: How do pelagic fisheries reorganize through seasons, environmental variability, fleet behaviour, and management interventions, and how can those dynamics inform adaptive decisions? Why it matters: Fast changes in resource availability and fishing operations require diagnostics that separate ecological availability, biological risk, fishing pressure, and fleet response.

Reproductive biology, growth and condition
Research question: How do reproduction, growth, and individual condition vary through time, and how do these life-history processes contribute to changes in pelagic population state? Why it matters: Maturity, spawning, growth, and condition can respond before biomass does, providing complementary information on population performance and resilience.

Scientific computing and research software
Research question: How can statistical methods, reproducible workflows, and research software make complex marine and fisheries analyses more transparent, reusable, and auditable? Why it matters: Heterogeneous marine data and complex models create hidden analytical variation; reusable software and reproducible workflows improve validation, transferability, and scientific efficiency.

Spatial ecology, species distribution and biodiversity
Research question: How do pelagic species, associated fauna, and non-target interactions vary across space and time, and which environmental processes shape habitat suitability and species distributions? Why it matters: Spatially explicit information from niche models, species distribution models, biodiversity observations, and bycatch patterns is needed to interpret ecosystem change and support spatial fisheries management.
Stock assessment and population dynamics
Research question: How do population processes, productivity, and model assumptions shape inference about the state and dynamics of exploited pelagic populations? Why it matters: Reliable assessment requires integrating biomass with recruitment, mortality, selectivity, and productivity while accounting for structural uncertainty in the models used for fisheries advice.

Provenance and graph contract
The graph is generated from public scholarly mirrors and curated website registries. Repository metadata enters the public graph only after it has been selected for a public Project, Software, or Teaching catalogue. ORCID and OpenAlex contribute public scholarly records and metrics; the raw repository catalogue is not serialized into this website graph.
