Improved fisheries management could offset many negative effects of climate change

The world’s oceans supply food and livelihood to billions of people, yet species’ shifting geographic ranges and changes in productivity arising from climate change are expected to profoundly affect these benefits. We ask how improvements in fishery management can offset the negative consequences of climate change; we find that the answer hinges on the current status of stocks.

Global change in marine aquaculture production potential under climate change

Climate change is an immediate and future threat to food security globally. The consequences for fisheries and agriculture production potential are well studied, yet the possible outcomes for aquaculture (that is, aquatic farming)—one of the fastest growing food sectors on the planet—remain a major gap in scientific understanding. With over one-third of aquaculture produced in marine waters and this proportion increasing, it is critical to anticipate new opportunities and challenges in marine production under climate change.

Unintended habitat loss on private land from grazing restrictions on public rangelands

Management of public lands, and who should have access to them, is often contentious. Most ranches in the western US rely upon seasonal grazing access to public lands, and conflict over biodiversity management has led to proposals to restrict grazing access on public lands.

Ecosystem-based management of Amazon fisheries and wetland

Infrastructure development and overfishing in the Amazon make it imperative to de- fine adequate scales for the ecosystem-based management of commercial fisheries and the wetlands on which they depend. We mapped fisheries and fish ecology data from Brazil, Peru, Bolivia and Colombia to an explicit GIS framework of river basins and mainstems. Migratory species account for more than 80% of the known maxi- mum catches of commercial fisheries across the Amazon.

University of California Strategies for Decarbonization: Replacing Natural Gas

The TomKat UC Carbon Neutrality Project was established in 2016 to develop and deploy solutions to mitigate climate change by capitalizing on the vast resources and researchers within the University of California (UC) system. The goal of the Project is to support innovative multidisciplinary research projects that will substantially accelerate progress of the University of California Carbon Neutrality Initiative. The Natural Gas Exit Strategies Working Group makes available its final report below.

Ambient changes exceed treatment effects on plant species abundance in global change experiments

The responses of species to environmental changes will determine future community composition and ecosystem function. Many syntheses of global change experiments examine the magnitude of treatment effect sizes, but we lack an understanding of how plant responses to treatments compare to ongoing changes in the unmanipulated (ambient or background) system. We used a database of long‐term global change studies manipulating CO2, nutrients, water, and temperature to answer three questions: (a) How do changes in plant species abundance in ambient plots relate to those in treated plots?

Asynchrony among local communities stabilises ecosystem function of metacommunities

Temporal stability of ecosystem functioning increases the predictability and reliability of ecosystem services, and understanding the drivers of stability across spatial scales is important for land management and policy decisions. We used species‐level abundance data from 62 plant communities across five continents to assess mechanisms of temporal stability across spatial scales. We assessed how asynchrony (i.e. different units responding dissimilarly through time) of species and local communities stabilised metacommunity ecosystem function.
