| Open AccessEstimating economic losses to tourism in Africa from the illegal killing of elephants
An ongoing elephant poaching crisis is threatening not only elephant populations but also the local economies that rely on nature-based tourism. Here, Naidoo and colleagues use an economic model to estimate the financial contribution of elephants to tourism and the possible consequences of their loss.

| Open AccessLand-use choices follow profitability at the expense of ecological functions in Indonesian smallholder landscapes
Small-scale farmers in Southeast Asia are increasingly turning to monocultures of oil palm and rubber to maximize income. Clough and colleagues demonstrate that this land-use change in Indonesia comes at a cost to a wide array of ecosystem functions and biodiversity.

| Open AccessDisaggregating the evidence linking biodiversity and ecosystem services
Biodiversity can enhance ecosystem services such as crop pollination. Here, Ricketts et al. synthesize 14 years of literature to show that biodiversity-ecosystem services relationships depend on the service, how services and biodiversity are each measured, and the approach used to link them.

| Open AccessClimate analogues suggest limited potential for intensification of production on current croplands under climate change
Simulations of the impact of future climate change on crop yield vary considerably. Here, the authors use a climate analogue approach to estimate the response of maximum attainable yield to climate change and predict that large shifts in land use and crop choice would be required to meet demand.

| Open AccessCompositional diversity of rehabilitated tropical lands supports multiple ecosystem services and buffers uncertainties
Land use becomes more diverse when it considers uncertain interactions of multiple ecosystem services. Here, Knoke and colleagues show that uncertainty plays a larger role if ecosystem services are optimized only for a single service, or if services correlate.

Correlated loss of ecosystem services in coupled mutualistic networks
Species interactions are known to promote biodiversity and ecosystem stability. Here, the authors assess the effect of habitat alteration on a species network that considers multiple interaction types, and find that plants mediate the response of pollinators and seed dispersers to habitat degradation.

| Open AccessCaribbean-wide decline in carbonate production threatens coral reef growth
Coral reef health is declining globally and is projected to lead to net loss of reef structure. This study shows that ecological change across the Caribbean has reduced reef growth rates to levels lower than those measured over the last ~8,000 years, threatening the ability of reefs to keep pace with future sea-level rise.

| Open AccessHigher levels of multiple ecosystem services are found in forests with more tree species
Tree diversity is thought to benefit forest ecosystems, but evidence from large-scale studies is scarce. This study of a 400,000 km2forest area shows that higher tree species richness supports higher levels of multiple ecosystem services, and therefore also a more sustainable management of production forests.

| Open AccessAnts and termites increase crop yield in a dry climate
The presence of earthworms is known to enhance the quality and moisture of soil in cool and wet climates. Evanset al. show that termites and ants can improve soil quality in warmer and drier climates—their presence results in elevated water infiltration and nitrogen content, leading to increased wheat yields.
