Ecologist Daniel H. Janzen has spent virtually all of his half-century career trying to catalogue and understand the creatures in a patch of dry tropical forest in northwestern Costa Rica. Little did he realize his efforts would evolve into building a sea-to-summit conservation area — and a drive to inventory all million species in the country in partnership with the Costa Rican government.
Plants have to defend themselves against drought, enemies and disease. But different threats demand different responses. So how do plants know what’s attacking them?
The moss world will never be the same. The moss Norwegian researchers thought they knew has played a trick on them. In return, researchers are calling on the Norwegian public to name a new species.
The fungus kills frogs, toads and salamanders, and now we know where it emerged. The pet trade may be to blame.
A lot of birdwatchers like the bullfinch. They’ve probably noticed that the female can chase off the more colourful male from the bird feeder. That makes this species different.
Should we reintroduce animal species that have died out? New technology may offer opportunities that no one could imagine a few decades ago. But the answer may not be as simple as you think.
The passenger pigeon was once among the most numerous species on earth. The last passenger pigeon died in the Cinncinati Zoo just over 100 years ago. How did it all go so wrong?
The NTNU University Museum’s animal collection is approaching a landmark one million specimens. We take a peek behind the scenes.
A group of researchers spent twelve seasons making some house sparrows bigger and others smaller. Their experiment yielded some important answers.
The relationship children have with their parents can sometimes influence the relationship they have with their teachers. Now we know more about why.
Why do some sparrows hatch six chicks while others don’t hatch any? How does upbringing affect the remainder of their lives? Physiological stress in the nest can actually affect birds’ DNA and possibly their lifespan.
Did some of our human features evolve while our ancestors were living in water? The aquatic ape theory has been disregarded by paleoanthropologists, but it deserves another chance.
Bird songs have many functions, but their main purpose is to attract a mate. Some of the best avian singers are described below.
Whether you are religious or not does not matter so much. You regret one-night stands about as much as other people do.
The Japanese eat one in ten of the world’s fish, and 80 per cent of the planet’s prized —and critically threatened — Bluefin tuna. Tuna aquaculture pioneered at Kindai University in Japan offers hope for both fish lovers and the fish.
Women regret saying yes to casual sex much more often than men do. Men – almost exclusively – regret saying no. Why?
Advances in our understanding of the developmental history of plants is turning botanical gardens worldwide on end.
