There's been quite a bit of discussion on these subjects lately, in this
forum.
 
A new publication brings together 18 scientific papers under the title 'The
conservation of bees'.  To quote from the dust jacket:
 
Bees form a vital part of many natural and farmed landscapes all over
the world.  Both as pollinators and as a part of the wider insect
community, their activities not only promote healthy ecosystems but in
many cases are essential to the life cycles of particular plant species.
Their complex coevolutionary relationships to their forage plants are a
subject of fascination to biologists and conservationists, and of
economic importance to crop managers.
 
But everywhere bees are under pressure, both from the direct impact of
pesticides in the environment as well as the indirect effects of habitat
alteration and destruction.
 
This volume focuses on a number of important topics in bee biology and
conservation in the temperate regions of four continents.  The varieties
of habitats needed for bees to thrive, the essential links and interactions
between bees and many plant species, and the current state of bee
biodiversity and conservation are all dealt with by an international cast of
authors.
 
Anyone with an interest in bees, or in insect and plant conservation in
general, will find important subjects discussed in this book.
 
End of quote.
