Counterintuitively, scincines from India and Sri Lanka have distinct biogeographical origins despite a long tectonic association between these landmasses, suggesting at least two independent, long-distance, trans-oceanic dispersal events into the subcontinent. Our biogeographic analyses suggest that scincines likely originated in East and Southeast Asia during the late Cretaceous (&lt;i&gt;ca&lt;/i&gt;. 70 Ma), and eventually dispersed westwards to Africa and Madagascar, where their greatest current-day species richness occurs.&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;Our study demonstrates the concomitant roles of dispersal and extinction in shaping modern-day assemblages of ancient clades such as scincine lizards.

The Nanyang Basin and surrounding mountains regions (NBSM) was identified as a critical shared refuge and hybrid zone, facilitating interspecific introgression through at least two putative hybridisation events. During the Late Pleistocene glacial cycles, introgressive hybridisation of these species occurred in the NBSM, followed by rapid expansion and colonisation of heterogenous habitats during interglacial cycles, with dispersal corridors largely aligning with the local river system.

We identified 60 consensus indicator species, mostly species of forest-steppe habitats, with species of mesic grasslands also well represented. The current maxima of vascular plant species richness exceed 110 species per 10–16 m&lt;sup&gt;2&lt;/sup&gt;. These maxima have been recorded in three regions: the Prut-Siret Interfluve in western Ukraine, the NW Transylvanian Basin in Romania and the White Carpathian Mts in the Czech Republic.&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;The extremely species-rich peri-Carpathian forest-steppe grasslands are confined to a geographically well-defined area of East-Central Europe. The observed fine-scale species richness of vascular plants is currently the highest known in the world.

Such surveys may accumulate large datasets that could further elucidate trends in abundance and distribution. However, the as-needed surveying of proposed activities may impart a sample site selection bias on the data if used for another purpose. Management of a threatened, forest-nesting seabird offered an example of this. Here we assessed how resource management planning and survey requirements can bias clearance monitoring survey data collected prior to proposed timber harvests, if those data are used for other purposes.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Location</h3>\u0000 \u0000 <p>Oregon and Washington, USA.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Taxon</h3>\u0000 \u0000 <p>Marbled Murrelet (<i>Brachyramphus marmoratus</i>).</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Methods</h3>\u0000 \u0000 <p>To assess how timber planning and other factors influenced marbled murrelet survey location selection, we used logistic regression models to examine habitat associations of marbled murrelet survey sites (<i>n</i> = 9178) encompassing proposed timber harvests, and the survey stations (<i>n</i> = 38,923) therein, across the murrelet's inland range in Washington and Oregon, USA between 1989 and 2021.

The strength of selection for each covariate changed over time, such that a habitat characteristic strongly influenced location selection in a year but was less influential in another year.
