As large marine predators, seabirds usually sit at the top of the food chain. But our new study, published in The American Naturalist, demonstrates this isn’t always the case.
We show how large, predatory arthropods can play an important role in the food webs of island ecosystems. And the Phillip Island centipede achieves this through its highly varied diet. Read more:
A well-armed predator stirs in the night
This centipede can grow to almost one foot (or 30.5cm) in length. It is armed with a potent venom encased in two pincer-like appendages called “forcipules”, which it uses to immobilise its prey. Its body is protected by shield-like armoured plates that line each of the many segments that make up its length.
¿Ayudan los árboles invasores a mitigar el cambio climático?

¿Contribuyen los árboles invasores a mitigar el cambio climático? Un buen número de expertos defiende desde hace años que plantar especies arbóreas foráneas (eucaliptos, pinos y acacias en España) en ecosistemas sin árboles, como pastizales y estepas, es una de las alternativas planteadas por algunos expertos para mitigar el
calentamiento global, al considerar que ayuda a capturar parte del carbono liberado a la atmósfera en forma de dióxido de carbono (CO2). Pero un reciente estudio científico ha venido a cuestionar esta opción.
Have you been researching the ecology of R. attenuata for a long time?
No, this discovery happened by chance. Some years ago, I began studying the defensive behaviors of various insect species that live in farmland areas. Up until now, I have provided frogs with over 50 insect species to investigate their defenses against frogs. I place a frog and an insect in a plastic case and observe their interaction. Frogs can catch insects with their tongues in the blink of an eye. In order to investigate what kind of defense mechanism the insect used, and to confirm whether it was eaten or managed to escape, I film this interaction and then play it back in slow motion.
