The ongoing sixth mass species extinction is the result of the destruction of component populations leading to eventual extirpation of entire species. Populations and species extinctions have severe implications for society through the degradation of ecosystem services. Here we assess the extinction crisis from a different perspective. We examine 29,400 species of terrestrial vertebrates, and determine which are on the brink of extinction because they have fewer than 1,000 individuals. There are 515 species on the brink (1.7% of the evaluated vertebrates).
The state of ecosystems and the health and well-being of people that depend on them are fundamentally linked. However, these links are often obscured – geographically, as globalised trade separates production of goods and ecosystem services from consumers; across time, as physical and mental impacts accumulate across lifespans; and through the complexity of competing socio-economic and cultural influences. Pervasive societal dualisms like nature-culture, and even social-ecological, fragment thinking and decision-making. Definitions differ across sectors.
The UN Biodiversity Lab is an online platform that allows policymakers and other partners to access global data layers, upload and manipulate their own datasets, and query multiple datasets to provide key information on the Aichi Biodiversity Targets and nature-based Sustainable Development Goals.
The ecosystems of small islands in the Southwest Pacific (the sixth expedition of the SS "Callisto") / J.C. Pernetta and H.I. Manner (eds.)
The main objective of the expedition was to compare as large a series of islands of different climatic conditions, ages and geological origins as possible. This necessitated short visits to each selected island. The structure and components of the ecosystem under study were the focus of attention, while their functioning was considered to be of secondary importance.

The Wetland Education and Training (WET) Program at Sydney Olympic Park is offering the following webinar in December.
In June 5–9, 2017, during the United Nations (UN) Ocean Conference, 143 governments, signatory parties of the Convention on Biological Diversity (CBD) declared their commitment and strategies to reach several objectives of the Sustainable Development Goal (SDG) 14, which stands to “conserve and sustainably use the oceans, seas and marine resources for sustainable development”.
The magnitude and pace of global change demand rapid assessment of nature and its contributions to people. We present a fine-scale global modeling of current status and future scenarios for several contributions: water quality regulation, coastal risk reduction, and crop pollination. We find that where people’s needs for nature are now greatest, nature’s ability to meet those needs is declining. Up to 5 billion people face higher water pollution and insufficient pollination for nutrition under future scenarios of land use and climate change, particularly in Africa and South Asia.
Coral reefs underpin a range of ecosystem goods and services that contribute to the well‐being of millions of people. However, tropical coral reefs in the Anthropocene are likely to be functionally different from reefs in the past. In this perspective piece, we ask, what does the Anthropocene mean for the provision of ecosystem services from coral reefs? This synthesis of the coral reef ecosystem services literature suggests the field is poorly prepared to understand the changing service provision anticipated in the Anthropocene.
In Hawai‘i, reefs provide more than $836 million in flood protection benefits to people, property and jobs every year—more than every other state and territory in the nation, according to a new report released by the U.S.
