Author Tom Iliffe leads scientists on a cave dive.
Scientific fieldwork that happens underground and underwater in spectacular but dangerous caves opens a window on a largely unknown world.
In the Global Biodiversity Information Facility there are 682,447 records of human encounters with dandelions.
Does big data threaten how humans explore the natural world? We need to protect our impulses to observe, compare, play, discover and love, no matter what technological capabilities are available.
Autumn edible mushrooms, mostly Boletus edulis.
The global mushroom industry is worth $35 billion yearly and growing. But mushrooms and other fungi play important ecological roles that scientists are still learning about – and some may be endangered.
Peruvian potatoes and black corn.
Over half the calories humans eat today come from corn, wheat and rice. Raising a greater diversity of types of crops and animals (agrobiodiversity) makes diets healthier and farming more resilient.
Seagrass is a nursery ground for fish.

Seagrass medows support rich biodiversity. New research shows what you can do to protect them.
Citizen scientists collecting soil and fine-roots from under unhealthy plants.

Humans - the very "carriers" who can spread dangerous microbes unthinkingly from their equipment and shoes - can instead become the first line of defence against a possible microscopic invasion.
A long-term monitoring project in Simpson Desert provides crucial information about the ecosystem.
Australia is among seven countries contributing to more than half of the world's biodiversity loss. Yet next month, a crucial network of long-term research sites will lose funding.
Sulawesi, part of the biogeographical region of Wallacea, is home to tarsiers – tiny, goggle-eyed creatures look more like mammalian tree frogs than monkeys.
The central islands of Indonesia, also known as Wallacea, is a place of wonder, a living laboratory for the study of evolution.
A synthesis centre in Africa would get an African perspective on global socio-environmental challenges.
A synthesis centre in Africa would massively improve the ability of researchers to understand complex scientific problems.
Orca family group at the Bremer Canyon off WA’s south coast.
The government aims to dramatically reduce the areas offered full protection and expand zones where fishing is allowed, while also claiming that this will still deliver good conservation.
Adélie penguin at the Mt Siple breeding colony, West Antarctica.
Climate change is set to expand Antarctica's ice-free area, potentially helping native species to flourish but also paving the way for invasive species to gain a foothold.
The High Line in New York City, a former elevated railroad trestle converted to a public park.
In an urbanizing world, people increasingly are seeking out nature in cities. Research shows that diverse species of animals, plants and insects can thrive in areas that humans have altered.
Gyala Peri and Namcha Barwa - Tibet.
On the Tibetan plateau, the village of Yunta shows that animals and humans can live peacefully and care for each other.
Angustoniscus amieuensis, a New Caledonian cockroach that lives in the moist forests of the island.
The theory that New Caledonia was a piece of land that separated from the ancient supercontinent of Gondwana was a seductive one. But then a cockroach rose up to challenge it.
Hundreds of large old trees were removed when the Hume Highway was widened.
When the Hume Highway was widened, hundreds of nest boxes were installed to replace habitat for three threatened species. Four years of monitoring has concluded the program is entirely unsuccessful.
Dingoes can help manage devastating red fox and feral cat numbers, but only if we let enough of them live in key areas.
Dingoes and wolves can help control destructive smaller predators, new research shows, but only if we encourage them across wide areas.
The Pinocchio anole lizard (Anolis probiscis) was first described in Ecuador in 1953, then believed to have become extinct until it was rediscovered in 2005.

'Doom and gloom' messages about nature are less effective than positive ones. The Lost & Found project tells the stories of creatures thought long gone but eventually rediscovered.
The declining fishing yield in the Lake Tanganyika region is being exacerbated by an influx of refugees.
Climate change, deforestation, overfishing and hydrocarbon exploitation threatens one of Africa's oldest lake's, Lake Tanganyika.
The future of cities?
Pollution, poverty, disease and death: future cities will be grim places, unless we do things differently.
Fish leave bits of DNA behind that researchers can collect.

Animals shed bits of DNA as they go about their lives. A new study of the Hudson River estuary tracked spring migration of ocean fish by collecting water samples and seeing whose DNA was present when.
