Topics about "parasites" include:

  1. Autumn leaf colouration
    Autumn colours are likely to be adaptive, as the 'default' is simply to remain green up to leaf fall, and both red and yellow leaf colouration have evolved independently on many occasions in gymnosperms and woody angiosperms.

Topics containing the search term "parasites" are:

  1. Dicyemids and chromidinids: enigmatic endoparasites
    Dicyemids and chromidinids are tiny, worm-like or 'vermiform' creatures that typically live inside the kidneys ('renal organs') of cephalopod molluscs such as octopus, squid and cuttlefish.

  2. Brood parasitism in cuckoos and other birds
    Obligate brood parasitism has evolved several times independently in birds. Apart from the cuckoos, it can be found in four other, only distantly related families.

  3. Malodorous flowering plants
    Several groups of angiosperms have flower structures that produce foul odours to attract pollinating insects. This strategy is convergent, being found in species as distantly related as the 'Titan arum' Amorphophallus titanium (a monocot) and the 'Corpse flower' Rafflesia (a eudicot).

  4. Foam nests in animals
    Nests crop up everywhere, but one made out of foam? Might not sound like a great idea, but it is. And no surprise, it has evolved several times...

  5. Mimicry in fungi
    Insects pollinating flowers are a familiar sight. But what happens when the "flower" is actually a fungus? Still "pollination", but now it is fungal spores. Read on to learn more about the fungi that mimic flowers...

  6. Explosive discharge in fungi and plants
    The very rapid release of reproductive bodies is perhaps most famous in the fungi, where several methods of flinging spores at high velocity have evolved independently.

  7. Autumn leaf colouration
    Autumn colours are likely to be adaptive, as the 'default' is simply to remain green up to leaf fall, and both red and yellow leaf colouration have evolved independently on many occasions in gymnosperms and woody angiosperms.

  8. Mushrooms and their relatives (Basidiomycota)
    Mushrooms are not only tasty, but also provide numerous examples of evolutionary convergence...

  9. Corneal nipple arrays in insect eyes
    Anti-reflection coating? Not only on mobile phone displays, but also on insect eyes...

  10. Biological uses of silk: from webs to ballooning
    What material is so versatile that it can be used for capturing prey, building nests, communication and even cleaning? The answer: that most remarkable of biomaterials - silk.

  11. Ants: insights into convergence
    Trap-jaws, silk and agriculture – just a few examples of convergence in the arguably most successful group of insects, the ants…

  12. Transparent tissues: eyes, bodies and reflective surfaces
    Read on if you want to know about the numerous animal equivalents to the invisible man...
