Seedkeeping can create a sense of home, reconnect communities with ancestral crops and preserve biodiversity and culturally significant crops for future generations.
Trees and shrubs in cold-weather climates rely on certain signals, such as temperature and light, to know when to leaf out and bloom. Climate change is scrambling those signals.
We identify a few harmless spiders you’ve probably seen around the house and backyard — and a few that are best avoided.
With their vibrant blooms and a lineage tracing back to the ancient supercontinent of Gondwana, wattles have a lot going for them.
The weather is warming up, and snakes are coming out to bask in the sun. But we don’t need to tell tall tales to appreciate snakes – the truth is far more fascinating.
Global warming has increased plant growth and helped offset increases in carbon dioxide emissions.
One bee may lay thousands of offspring in late spring. Give her room to build a nest and manage her reproductive duties.
Humans obtain bacteria through the foods they eat. But how do bees collect bacteria that live in and on them? And where do they pick up these microbes?
While many plant species fail to germinate, some mammals may wake up to a landscape devoid of prey.
Climate change has advanced the arrival of spring by as much as several weeks in some parts of the US. This can mean major crop losses and disconnects between species that need each other to thrive.
If you get hay fever, minimising your exposure to grass pollen is likely to be useful. Fortunately, it’s becoming easier to keep track of the pollen count. But what do you do when it’s high?
Monitoring the timing of recurring biological events is key to understanding the effects of climate change.
Dry and warm conditions in winter are set to continue into spring, and the likely culprit is the positive Indian Ocean Dipole
Why does the impact of rain in a puddle look different from when it falls elsewhere, like in a lake or the ocean? A ‘puddle equation’ dives deep into the secret math of ripples.
If you are bitten by a tick, you need to find out what species it was, fast. A research team has developed a website to help people in Quebec, Ontario and New Brunswick do just that.
Easter is actually a mish-mash of different traditions celebrating the coming of spring.
Record heat in February 2019 caused shock and delight in equal measure. Behind the balmy weather lie challenges for British wildlife.
The reason we have seasons is because, during its journey around the Sun, the Earth is tilted.
Study shows that the availability of springs may have controlled human evolution.
