Global biodiversity change is one of the most pressing environmental issues of our time. Here, we review current scientific knowledge on global biodiversity change and identify the main knowledge gaps. We discuss two components of biodiversity change—biodiversity alterations and biodiversity loss—across four dimensions of biodiversity: species extinctions, species abundances, species distributions, and genetic diversity. We briefly review the impacts that modern humans and their ancestors have…

Global Climate Change and Biodiversity: Issues and Future Research

Biological diversity, commonly referred to as biodiversity, is a measure of variation of life forms within a given species, ecosystem, biome, or planet [1-3]. Biodiversity includes diversity within
Essential Biodiversity Change Indicators for Evaluating the Effects of Anthropocene in Ecosystems at a Global Scale
Understanding and predicting the impact of global change drivers on biodiversity, the basis of the delivery of goods and services to humans, is a critical task in the Anthropocene Era. This has led
Biodiversity scenarios neglect future land‐use changes
It is argued that the current state of integration between ecological and land system sciences is leading to biased estimation of actual risks and therefore constrains the implementation of forward-looking policy responses to biodiversity decline and suggests research directions at the crossroads between ecology and environmental sciences to face the challenge of developing interoperable and plausible projections of future environmental changes.
Biodiversity monitoring, earth observations and the ecology of scale.
From this analysis emerges an actionable approach for measuring, monitoring and forecasting biodiversity change, highlighting key opportunities to establish EO as the backbone of global-scale, science-driven conservation.
Global meta-analysis reveals no net change in local-scale plant biodiversity over time
No general tendency for local-scale plant species diversity to decline over the last century is found, calling into question the widespread use of ecosystem function experiments and directly contradicts the key assumption linking experimental results to ecosystem function as a motivation for biodiversity conservation in nature.
Interactions between climate change and land use change on biodiversity: attribution problems, risks, and opportunities
Global change drivers are known to interact in their effects on biodiversity, but much research to date ignores this complexity. As a consequence, there are problems in the attribution of
Spatial and topical imbalances in biodiversity research
The distinct spatial imbalances in biodiversity research must be filled, research capacity built, particularly in the Global South, and spatially-explicit biodiversity data bases improved, curated and shared.
International cooperation for biodiversity conservation : an economic analysis
Biodiversity decline poses significant threats to current and future generations. Although species extinction has been a natural process since the formation of Earth, recent rates of extinction are


Impacts of climate change on the future of biodiversity.
Overall, this review shows that current estimates of future biodiversity are very variable, depending on the method, taxonomic group, biodiversity loss metrics, spatial scales and time periods considered.
Biodiversity Conservation: Challenges Beyond 2010
It is argued that more radical changes are required that recognize biodiversity as a global public good, that integrate biodiversity conservation into policies and decision frameworks for resource production and consumption, and that focus on wider institutional and societal changes to enable more effective implementation of policy.
Beyond Predictions: Biodiversity Conservation in a Changing Climate
This work introduces a framework that uses information from different sources to identify vulnerability and to support the design of conservation responses, and reviews the insights that different approaches bring to anticipating and managing the biodiversity consequences of climate change.
Scenarios for Global Biodiversity in the 21st Century
Scenarios consistently indicate that biodiversity will continue to decline over the 21st century, however, the range of projected changes is much broader than most studies suggest, partly because there are major opportunities to intervene through better policies, but also because of large uncertainties in projections.
Modeling biodiversity dynamics in countryside landscapes.
A framework for assessing the relative vulnerability of species to extinction in the countryside, based on the Skellam model of population dynamics, is presented and the resulting ranking of vulnerabilities is significantly correlated with the World Conservation Union (IUCN) Red List assessment.
Towards the global monitoring of biodiversity change.
Global State of Biodiversity and Loss
The dimensions and nature of the Earth's terrestrial biodiversity are examined, and the scientific facts concerning the rate of loss of biodiversity and the drivers of this loss are reviewed.
The Impact of Conservation on the Status of the World’s Vertebrates
Though the threat of extinction is increasing, overall declines would have been worse in the absence of conservation, and current conservation efforts remain insufficient to offset the main drivers of biodiversity loss in these groups.
Global Biodiversity: Indicators of Recent Declines
Most indicators of the state of biodiversity showed declines, with no significant recent reductions in rate, whereas indicators of pressures on biodiversity showed increases, indicating that the Convention on Biological Diversity’s 2010 targets have not been met.
Wildlife in a changing world : an analysis of the 2008 IUCN red list of threatened species
Wildlife in a Changing World presents an analysis of the 2008 IUCN Red List of Threatened Species, and provides the latest information on the patterns of species facing extinction in some of the most important ecosystems in the world.
