Biologists are finding new evidence that these ocean invertebrate grazers don't just ingest whatever they catch. They can actually be picky eaters – and their choices might influence ocean food webs.
Pacific seabirds, such as this Great Blue Heron, can accumulate mercury in their bodies from the fish they eat.
Mercury levels in seabirds living off the coast of British Columbia have been stable in recent years. New research suggests that this may be due to changes in their diet, not pollution control.
Scientists are pioneering a new way of monitoring water species, using techniques more familiar to fans of crime scene TV shows.

Viruses are not all bad. In fact, many ecosystems would not function without them.
The word "virus" strikes terror into the hearts of most people. But most viruses are actually vital to our very existence.
‘I don’t do public transport.’
Bat populations have been hammered by deforestation. Efforts like tree-planting schemes are a step forward, but they're doomed to fail unless we apply a bit more local knowledge.
Thylacines are extinct - and perhaps we just have to accept it.
Many ecosystems have changed so radically that it is no longer possible to restore them to what they once were and in other situations it is not appropriate.
Each year more than 15 billion trees are lost worldwide, according to a major new study.
Waterbugs are used for the monitoring of river ecosystem health across the world.
Around the world, waterbugs are the most widely-used indicator of environmental health and pollution of rivers, lakes and wetlands.
You couldn’t just plop dinosaurs anywhere and expect them to survive.
A "Pleistocene Park" might be a more realistic scenario.
They might look static, but trees are dynamic living things - just on a different time scale to us.

Trees are more like us than you might think. They even have a pulse. They just operate over much slower timescales.
Coral reefs are like an underwater metropolis – and function in similar ways.
Consensus is growing that we are steering towards a sixth mass extinction event. There are calls for increased efforts to stop the accelerating loss of plants and animals. But do we really need to protect…
Every living organism needs the same five basic processes – and we can now model ecosystems on them.
It may sound overly simple, but just five processes can define us as animals: eating, metabolism, reproduction, dispersal and death. They might not seem like much, but, thanks to a mathematical model from…
Are you feeling inspired from watching the Chelsea Flower Show? Do you long for an immaculate, well-designed garden, full of well-behaved plants, brimming with colourful flowers and attractive foliage…
Ducking for cover.
Declining numbers of zebra, antelope and other big grazers cause rodent populations to rapidly increase, a new study has shown. Published in the Proceedings of the National Academy of Sciences, Hillary…
