Bugs, bees and beasties- Bio-diversity matters

If you are a student you will have an athens code. You will have to ask the college for it. You can access all sorts of stuff from scientific papers and journals to maps and all the bs standards for free

nobody told me that! I would have been downloading science papers like a loon otherwise!

 

Thanks gibbon

Thats a very well researched and written paper (IMO) it is interesting but should not surprise anyone that Long Term Ecological Research at WARRA in Tasmania has established almost identical obligate relationships between certain saproxylic beetles and large diameter deadwood (Euc) habitat - along with associated wood decay fungi - of course!

The bees in japan have evolved ways of dealing with this, they the hornets, are just another expression of natures imagination and another example of adaptions within a species to a problem.

 

got to love that biodiversity

■ Saproxylic beetles play an important role in

decomposition processes and thus for nutrientcycling in natural ecosystems. Many are also involved

in pollination.

■ Many saproxylic beetle species remain widely

distributed in Europe, although their populations and

ranges have suffered significant long-term decline.

■ Much is left to learn about the saproxylic beetles of

Europe. The knowledge of the biology and therefore

the status of many species is still largely insufficient.

■ Few European countries - if any - have any kind of

organised and systematic monitoring for saproxylic

beetle species. There is a clear need for drawing

together information on all initiatives under way or

planned, and for a wider European saproxylic beetle

conservation action plan to be explored, developed,

and undertaken.

■ The main long-term threats identified are habitat loss

in relation to logging and wood harvesting and the

decline of veteran trees throughout the landscape, as

well as lack of land management targeted at promotion

of recruitment of new generations of trees. More

short-term and localised threats arise from (often illinformed) sanitation and removal of old trees due

to (often misconceived) safety constraints, in places

heavily used by people.

■ Raising awareness among conservation professionals

and resources managers about the needs of saproxylic

organisms is crucial, as they depend on the dynamics

of tree aging and wood decay processes, which in

turn have implications for land management - nonintervention or minimum intervention in former

wood pasture can prevent the renewal of old trees

and be very damaging and livestock grazing can be

essential to maintain adequate habitats.

■ Historical continuity of suitable veteran trees is also

important - old growth - but this is not addressed yet

by the EU Habitats Directive process and there is an

urgent need of attention.

■ This new analysis of the European threat status of the

selected saproxylic beetles will provide an important

resource for when the current lists on the Habitats

Directive Annexes and on the Bern Convention

Appendices are next reviewed.

■ This project contributes to improving the coverage of

invertebrates on the global IUCN Red List, thanks

to the assessment of endemic European saproxylic

beetles.

■ The taxonomic coverage of this Red List requires

expanding as only a small proportion of Eu

Your post about the Japanese Hornet reminded me of this news story from a week or so back.. Wasps drop ants to take their food - ABC News (Australian Broadcasting Corporation)

Sounds kinda funny cunjures up all kinds of imagery...and the video lives up to all that... [ame=http://www.youtube.com/watch?v=DILNPkA9vwY]YouTube - Ant dropping behaviour by wasps[/ame]
