There is a lack of comparison between future warming and its most recent climate analogue 3.25 million years ago during the mid-Piacenzian warm period. We have attempted to fill this knowledge gap by modelling the zonation of woody plant communities during the mid-Pliocene and comparing it with their current distribution and predictions of their future distribution.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Location&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;Europe.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Time Period&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;3.25–3 million years ago, 1970–2000, and 2081–2100.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Taxon&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;European tree species.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Methods&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;In this study, we selected 15 European tree species from three main European forest ecosystems: Mediterranean, temperate and boreal species that had ancestors present in Europe during the mPWP. Then we applied an ensemble model using climatic data from the mPWP, modern and two future climate scenarios. In order to compare the models, we assessed the overlapped area as well as Dutilleul's modified t-test in order to assess the spatial similarities in forest communities distribution between the mPWP and future warming.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Results&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;Our results showed that there is a clear northern trend in the northward shift of forest communities under all warming scenarios. Across all species, there is a clear drop in suitable area with the exception of Mediterranean species, where suitable area increased in all warm scenarios. When comparing the mPWP with future warming, there is evidence to support that RCP 4.5 will potentially exhibit similar conditions, while RCP 8.5 may result in highly novel habitats.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Main Conclusions&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;Although mid-Pliocene conditions are more analogous to the RCP 4.5, it raises an urgent ecological concern for adaptive forest management.

This enormous level of plant diversity has played a fundamental role in the diversification of the eriophyoids. Ozman-Sullivan and Sullivan (2023) estimated there are at least 250,000 eriophyoid species, with most species highly likely to be in the largely neglected subtropical and tropical regions. Li and Xue (2024) argued that there could be far less than 250,000 eriophyoid species. We assert that this high number is realistic and possibly conservative. As an example, Ozman-Sullivan and Sullivan (2023) reported that just 11 well-studied plant species collectively host ~200 eriophyoid species. Habitat destruction and climate change represent increasingly dire threats to the existence of thousands of plant species and their dependent eriophyoid species across the world.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Location</h3>\u0000 \u0000 <p>Global.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Taxon</h3>\u0000 \u0000 <p>Eriophyoid mites (Acari: Eriophyoidea).</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusions</h3>\u0000 \u0000 <p>We present more evidence to support our estimate of at least 250,000 eriophyoid species, including a substantial tropical majority.
