As the urgency to evaluate the impacts of climate change on marine ecosystems increases, there is a need to develop robust projections and improve the uptake of ecosystem model outputs in policy and planning. Standardizing input and output data is a crucial step in evaluating and communicating results, but can be challenging when using models with...

Interdisciplinary marine research is pivotal for addressing ocean sustainability challenges but may exclude diverse socio-economic, cultural, or identity groups. Drawing on perspectives of marine Early Career Researchers, we highlight the importance of Diversity, Equity, and Inclusion (DEI) in advancing interdisciplinary marine science and present...

Interdisciplinary marine research is pivotal for addressing ocean sustainability challenges. While interdisciplinary research brings together a diversity of disciplines, we ask: ‘does it bring together individuals and groups from diverse socio-economic, cultural, or identity backgrounds or does it favour only certain groups?’ This paper draws on th...

Shifts in spawning phenology may impact the early life stages of small pelagic fishes, affecting their first-year survival and recruitment. In Prince William Sound, Pacific herring is a key forage species that once supported commercial and subsistence fisheries for many decades, but collapsed in 1993 and has yet to recover. Starting in 1980, spawn...

Small pelagics, or forage fish, link lower and higher trophic levels in marine food webs. Recently, attention has been given to the management of forage fish, including anadromous river herring (Alewife Alosa pseudoharengus, blueback herring A. aestivalis) and American shad (A. sapidissima) due to their current depleted status and historically impo...

North Pacific marine heatwave, unprecedented sightings of juvenile white sharks (Carcharodon carcharias) emerged in central California. These records contradicted the species established life history, where juveniles remain in warmer waters in the southern California Current. This spatial shift is significant as it creates potential conflicts with...

The costs of monitoring species of concern in data-limited regions can hinder effective management. However, careful biological survey design can improve monitoring of critical areas, and help develop ecosystem-based approaches, including spatial management frameworks. The current study aims to reduce the cost of environmental monitoring of sea tur...

Reduction of ecosystem connectivity has long-lasting impacts on food webs. Anadromous fish, which migrate from marine to freshwater ecosystems to complete reproduction, have seen their historically larger ecosystem role undercut by widespread riverine habitat fragmentation and other impacts mainly derived from anthropogenic sources. The result has...

The wetland dynamics in eastern Amazon region during the last thousand years were studied by pollen analysis and AMS radiocarbon date. Three sediment cores were sampled from the Marajó Island, which is located at the mouth of the Amazon River. Marajó Island is covered mainly by Amazon coastal forest, herbaceous and varzea vegetation. One core was o...
