We collected long-term data on the abundance of European ground squirrels, Spermophilus citellus, in 64 colonies as part of the Hungarian Biodiversity Monitoring System to investigate the abiotic factors that could explain the spatial and temporal dynamics of populations in Hungary. We used information theory-based modelling and multi-model inference to investigate the effects of environmental and climate variables on relative population densities, using monitoring records of burrow counts as proxies for density collected annually between 2000 and 2018. We examined data carefully for any clues of inconsistencies, errors, or missing data, which resulted in 57% of the complete dataset. Results Our generalised additive models (GAM) with splines identified geographical location, year, and principal components reflecting winter temperature, precipitation, and summer temperature to affect population densities. Contour plots derived from the best GAM model uncovered increasing density in the Kiskunság and Kisalföld meso-regions with favourable water management characteristics and decreasing densities in the northern and southern regions, which in fact, cover floodplain of River Tisza and other flash-flood regions. Ambient temperature and precipitation of the wettest and warmest months during hibernation and summer contributed most to counts fluctuations, though these factors were dwarfed by spatial effects. Increased temperatures and aridification in the Kiskunság, because of the warming Pannonian ecoregion, seemed to positively affect counts. Conclusions Analysis of our reduced dataset indicated unidentified local factors or a spatial effect on demographic variability of ground squirrel populations. Those fluctuations underscore the necessity of research and management on local populations to identify the reasons of declines and adapt management accordingly to stop or change decreasing population trajectories. true false 2026 true true true false true false GOLD 2026-05-08 false http://www.frontiersinzoology.com/ 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 14 14 D1 false false false false 2026-07-09T08:01:13.599+0000 Talajtérképezési és Környezetinformatikai Osztály (HRN ATK / TAKI) 2 14 1 5 0 true Language 10002 /api/language/10002 Angol English true 2 true PersonAuthorship 137150343 /api/authorship/137150343 1 0.2 true false false Author 10019720 /api/author/10019720 Gedeon Csongor István true 10019720 true Gedeon Csongor István true false false AuthorshipType 1 /api/authorshiptype/1 0 true 0 true false true PersonAuthorship 137150344 /api/authorship/137150344 2 0.2 false false false Váczi Olivér true false false AuthorshipType 1 /api/authorshiptype/1 0 true 0 true false true PersonAuthorship 137150345 /api/authorship/137150345 3 0.2 false false false Knauer Felix true false false AuthorshipType 1 /api/authorshiptype/1 0 true 0 true false true PersonAuthorship 137150346 /api/authorship/137150346 4 0.2 false false true Author 10037338 /api/author/10037338 Árvai Mátyás true 10037338 true Árvai Mátyás true false false AuthorshipType 1 /api/authorshiptype/1 0 true 0 true false true PersonAuthorship 137150347 /api/authorship/137150347 5 0.2 false true false Suchentrunk Franz true false false AuthorshipType 1 /api/authorshiptype/1 0 true 0 true false true PublicationIdentifier 31815544 /api/publicationidentifier/31815544 PlainSource 6 /api/publicationsource/6 PublicationSourceType 10001 /api/publicationsourcetype/10001 true true true DOI DOI https://doi.org/@@@ true true 6 true IDENTICAL 10.1186/s12983-026-00608-3 https://doi.org/10.1186/s12983-026-00608-3 false true PublicationIdentifier 31815545 /api/publicationidentifier/31815545 PlainSource 40 /api/publicationsource/40 PublicationSourceType 10006 /api/publicationsourcetype/10006 true true true Egyéb URL Other URL @@@ true true 40 true IDENTICAL https://link.springer.com/10.1186/s12983-026-00608-3 https://link.springer.com/10.1186/s12983-026-00608-3 false true SjrRating 11656161 /api/sjrrating/11656161 49 0.1 journal RatingType 10002 /api/ratingtype/10002 sjr true true ClassificationExternal 1103 /api/classificationexternal/1103 true 1103 true D1 FROM_LAST_YEAR true true /api/publication/37069266 <div class="JournalArticle Publication long-list"> <div class="authors"> <img title="Forrásközlemény" style="float: left" src="/frontend/resources/grid/publication-core-icon.png"> <img title="Idézőközlemény" style="float: left" src="/frontend/resources/grid/publication-citation-icon.png"> <div class="autype autype0"> <span class="author-name" mtid="10019720"><a href="/gui2/?type=authors&mode=browse&sel=10019720" target="_blank">Gedeon Csongor István (<span class="authorship-author-name">Gedeon Csongor István</span> <span class="authorAux-mtmt"> Gedeon Csongor</span>) </a> </span> <span class="author-affil"><span title="HUN-REN Agrártudományi Kutatóközpont">HRN ATK</span>/<span title="Talajtani Intézet">TAKI</span>/Talajtérképezési és Környezetinformatikai Osztály</span> ;&nbsp;&nbsp;&nbsp;
