Once the fish factories and ‘kidneys’ of colder seas, Australia’s decimated shellfish reefs are coming back

Tue, 09/08/2022 - 04:58
Only 200 years ago, Australian waters were full of oyster and shellfish reefs. Then they collapsed. Now large scale restoration efforts are underway.

Artificial light at night can change the behaviour of all animals, not just humans

Thu, 28/07/2022 - 03:59
While artificially illuminating the night allows humans to make use of the the night, in doing so we catastrophically change the environment for all other species. How can we fix this?

The living world above our heads: how city trees help shape biodiversity

Tue, 12/07/2022 - 19:36
Trees were already known for cooling and cleaning the air of cities. A Europe-wide, participative science project shows how much their density matters for urban biodiversity.

Trophy hunting will not save Africa's lions – so the UK ban on imports is a positive step for wildlife conservation

Wed, 29/06/2022 - 12:23
An Africa-based conservation expert explains why trophy hunting has not delivered for wildlife in most parts of Africa, and that local communities benefit next to nothing from its continued practice Hans Bauer, Research fellow: Northern Lion Conservation, University of Oxford Licensed as Creative Commons – attribution, no derivatives.

The common eider sea duck contributes to its own conservation by donating its feathers

We know heatwaves kill animals. But new research shows the survivors don’t get off scot-free

Mon, 13/06/2022 - 21:04
Exposure to hot and dry conditions can damage the DNA of nestling birds in their first few days of life – meaning they age earlier and produce less offspring.
