Coral reefs: climate change and pesticides could conspire to crash fish populations

Coral reefs: climate change and pesticides could conspire to crash fish populations
Australia barely had time to recover from record breaking fires at the start of 2020 before the Great Barrier Reef experienced its third mass coral bleaching event in the past five years. Only five of these have occurred since records began in the 1980s. High water temperatures and marine heatwaves, caused by climate change, are making coral bleaching an almost regular occurrence in some parts of the world. Coral reefs are among the most vibrant ...

Importance of sediment flow for mangrove conservation and restoration

Mangroves
New guide will assist practitioners to assess role of sediment flows in mangrove conservation and restoration projects. Mangroves are an amazingly rich ecosystem, supporting biodiversity, providing natural resources and services – and thus supporting livelihoods – and storing carbon. They also offer a very effective defense against the effects of climate change on tropical coasts, protecting deltas from shrinking and sinking. But mangrove forests...

Blue Acceleration: our dash for ocean resources mirrors what we’ve already done to the land

Oil Rig
Humans are leaving a heavy footprint on the Earth, but when did we become the main driver of change in the planet's ecosystems? Many scientists point to the 1950s, when all kinds of socioeconomic trends began accelerating. Since then, the world population has tripled. Fertiliser and water use expanded as more food was grown than ever before. The construction of motorways sped up to accommodate rising car ownership while international flights took...

Microplastic pollution is everywhere, but scientists are still learning how it harms wildlife

Plastic
Plastic pollution is a growing global concern. Large pieces of plastic have been found almost everywhere on Earth, from the most visited beaches to remote, uninhabited islands. Because wildlife are regularly exposed to plastic pollution, we often ask what effects plastics have on the animals. Over time, macroplastics (plastic debris larger than five millimetres in size) break up into tiny particles called microplastics (smaller than five millimet...
