Differences of fl oral resource use between honey bees and wild bees in an intensive farming system

  1. Bees provide an essential pollination service for crops
  2. and wild plants. However, substantial declines in bee
  3. populations and diversity have been observed in Europe
  4. and North America for the past 50 years, partly due to the
  5. loss of natural habitats and reduction of plant diversity
  6. resulting from agricultural intensifi cation. To mitigate
  7. the negative effects of agricultural intensifi cation, agrienvironmental
  8. schemes (AES) have been proposed to
  9. sustain bees and other pollinators in agrosystems. AES
  10. include the preservation of semi-natural habitats such as
  11. grasslands, fallows, woodlots, hedgerows or set-aside
  12. fi eld margins. However, empirical evidence suggests that
  13. the use of those semi-natural habitats by bees may vary
  14. greatly among bee functional groups and may further
  15. be infl uenced by the presence of alternative foraging
  16. habitats such as mass-fl owering crops. The present study
  17. sets out to investigate whether the three bee groups
  18. typically targeted by AES (honey bees, bumble bees
  19. and other wild bees) differ in the way they use those
  20. semi-natural habitats relative to common mass-fl owering
  21. crops (oilseed rape, sunfl ower, alfalfa) in an intensive
  22. agricultural farming system. A clear segregation pattern in
  23. the use of fl oral resources appeared between honey bees
  24. and wild bees, with the former being tightly associated
  25. with mass-fl owering crops and the latter with semi-natural
  26. habitats. Bumble bees had an intermediate strategy and
  27. behaved as habitat generalists. Therefore, it would be
  28. sensible to treat the three bee groups with distinct AES
  29. management strategies, and to further consider potential
  30. effects on AES effi ciency of alternative foraging habitats in
  31. the surrounding. This study also stresses the importance
  32. of native fl oral resources, particularly in semi-natural
  33. herbaceous habitats, for sustaining wild bee populations.

Eight rules for walks in the country Posted by Tom Cox

  1. “It’s quite an up and down kind of walk,” said my friend
  2. Emma. “Oh,” added Emma, “and it gets a bit blowy up there,
  3. so I’d leave your credit card back here if I were you.” I gave
  4. her a searching look, wondering how a credit card might
  5. relate to a strong wind. “I took mine up there the other week
  6. and it blew out of my hand into the sea,” she clarifi ed. “I had
  7. to order a new one.”
  8. I fell in love with walking because it lifted my spirit
  9. and took me to parts of my local area that I would never
  10. have _________ otherwise, but also because there was
  11. something brilliantly ridiculous about the idea of _________
  12. yourself, on a whim, alone, in a bit of countryside you’d never
  13. _________ before, with no real goal apart from putting one
  14. foot in front of the other.
  15. I’ve never really dressed in any walking-specifi c clothing
  16. or taken any special supplies out with me, but I do think
  17. there are a few things I’ve learned about “how to walk” in
  18. gentle terrain that might help others. I have compiled some
  19. of the main ones: always be assertive in saying “Hello!”
  20. to fellow walkers, unless in a built-up area; learn to
  21. fold your map properly; show strange dogs and cows
  22. who is boss; don’t be afraid of dictaphones*; try not to
  23. have a beard, but if you do have a beard, have a dog as
  24. well; try to avoid headwear, unless strictly necessary;
  25. choose an apt soundtrack for your walk; watch out for
  26. fookwits and loonies!
  27. This last one doesn’t apply specifi cally to country walks.
  28. It’s just something that my dad tells me every time I see him,
  29. and it’s worked fairly well as a general rule for life over the
  30. years, so it probably works for walking as well. *voice recorders
