The uptake of the biosphere integrity planetary boundary concept into national and international environmental policy
The biosphere integrity planetary boundary was, at least partly, developed to aid policymakers in addressing the dangerous decline of Earth’s biodiversity. However, just over a decade since its origination the extent and speed of its adoption as a policy tool remains unclear. Here, we review the…

Assessing changing baleen whale distributions and reported incidents relative to vessel activity in the Northwest Atlantic.
Baleen whales are among the largest marine megafauna, and while mostly well-protected from direct exploitation, they are increasingly affected by vessel traffic, interactions with fisheries, and climate change. Adverse interactions, notably vessel strikes and fishing gear entanglement, often result…

Current and future patterns of global marine mammal biodiversity.
Quantifying the spatial distribution of taxa is an important prerequisite for the preservation of biodiversity, and can provide a baseline against which to measure the impacts of climate change. Here we analyse patterns of marine mammal species richness based on predictions of global distributional…

The biodiversity adaptation gap: Management actions for marine protected areas in the face of climate change
Abstract Marine protected areas (MPAs) are a crucial component of international biodiversity conservation commitments, yet are increasingly affected by climate change. No synthesis or analysis exists of the specific on‐the‐ground management actions that have been taken by MPA managers in response…

How many species are there on Earth and in the ocean?
The diversity of life is one of the most striking aspects of our planet; hence knowing how many species inhabit Earth is among the most fundamental questions in science. Yet the answer to this question remains enigmatic, as efforts to sample the world's biodiversity to date have been limited and…

Future ocean biomass losses may widen socioeconomic equity gaps
Numerous marine ecosystem models are used to project animal biomass over time but integrating them can be challenging. Here the authors develop a test for statistical significance in multi-model ensemble trends, and thus relate future biomass trends to current patterns of ecological and…

Future Climate‐Driven Ecological Disruption in a Network of Marine Protected Areas on Canada's East Coast
ABSTRACT Climate‐induced species range shifts alter ecological assemblages, yet little is known of the consequences for ecosystem functioning. We combine species distribution model (SDM) projections with species traits to develop a spatially explicit risk index for assessing climate change impacts…

A database of mapped global fishing activity 1950–2017
Abstract A new database on historical country-level fishing fleet capacity and effort is described, derived from a range of publicly available sources that were harmonized, converted to fishing effort, and mapped to 30-min spatial cells. The resulting data is comparable with widely used but more…

AquaX: An enhanced and revised AquaMaps framework to model marine species distributions and biodiversity
Marine biodiversity underpins ecosystem health and is critical for the provision of essential ecological services. Global efforts to mitigate biodiversity loss are underway but require comprehensive knowledge on the biogeography of species to be effective. However, key challenges limit…

Emergent Global Patterns of Ecosystem Structure and Function from a Mechanistic General Ecosystem Model
: This paper presents the first mathematical model that attempts to represent the biology and behavior of all individual organisms globally, taking us a step closer to holistic ecological and conservation science founded on mechanistic predictions. Anthropogenic activities are causing widespread…

Differing marine animal biomass shifts under 21st century climate change between Canada’s three oceans
Under climate change, species composition and abundances in high-latitude waters are expected to substantially reconfigure with consequences for trophic relationships and ecosystem services. Outcomes are challenging to project at national scales, despite their importance for management decisions…

Operationalizing climate risk in a global warming hotspot
Abstract Climate change is a looming threat to marine life, creating an urgent need to develop climate-informed conservation strategies. The Climate Risk Index for Biodiversity was designed to assess the climate risk for marine species in a manner that supports decision-making. Yet, its regional…

Advancing Global Ecological Modeling Capabilities to Simulate Future Trajectories of Change in Marine Ecosystems
Considerable effort is being deployed to predict the impacts of climate change and anthropogenic activities on the ocean's biophysical environment, biodiversity, and natural resources to better understand how marine ecosystems and provided services to humans are likely to change and explore…

Evaluating the relationships between the legal and illegal international wildlife trades
Abstract The international legal trade in wildlife can provide economic and other benefits, but when unsustainable can be a driver of population declines. This impact is magnified by the additional burden of illegal trade, yet how it covaries with legal trade remains little explored. We combined…

The Past and Future of the Fisheries and Marine Ecosystem Model Intercomparison Project
Abstract Climate change is increasingly affecting the world's ocean ecosystems, necessitating urgent guidance on adaptation strategies to limit or prevent catastrophic impacts. The Fisheries and Marine Ecosystem Model Intercomparison Project (FishMIP) is a network and framework that provides…
