<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial",sans-serif">Dear ILTER friends and colleagues,<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial",sans-serif"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial",sans-serif">As most of you know the decline in insect biomass that was recently published in a paper by Hallmann et al. in PlosOne (October 2017) raised enormous attention across the globe.
The underlying data were compiled by hobby entomologists over approximately 30 years in different German nature reserves.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial",sans-serif">I believe you all may agree that such a decline is not restricted to nature reserves in Germany but is most likely a common pattern across several parts of the world and also
not only restricted to insects. However this has to be proven.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial",sans-serif"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial",sans-serif">I wonder if there might be similar long-term datasets from various ILTER sites? If so, we may compile these data and write a joined paper on cross-taxa and cross-realm patterns
in global biodiversity decline?<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial",sans-serif">I am aware that similar studies have been done before (e.g. Bowler et al. 2017 Nature Ecology and Evolution) but I believe that there are still many unanswered questions and
many taxa groups that have never been included in such studies.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial",sans-serif"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial",sans-serif">I am sure you need to know more about the planned paper project than just a draft title. However, as we currently do not know how many datasets over which time periods, from
which ecosystems and countries might be available, we would rather like starting to draft an outline of such a paper after knowing what data might be available.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial",sans-serif"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial",sans-serif">Therefore, I would be happy if you could let me know if you may have long-term biodiversity data from an ILTER site that fulfills the following criteria:<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial",sans-serif"><o:p> </o:p></span></p>

<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial",sans-serif">- at least 10 sampling events during that time that are evenly distributed within the 15 years<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial",sans-serif">- no changes in sampling method, taxonomic resolution and season<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial",sans-serif">- the data of a certain time series are from the same site (no space-for-time substitution!)<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial",sans-serif">- data are digitalized and could be submitted within a few weeks<o:p></o:p></span></p>
