The influence of climate on morphometric traits of fossil populations of Microtus arvalis and M .  agrestis from the Carpathian Basin, northern Hungary

Abstract

In this study, we analysed morphometrically fossil populations of Microtus arvalis and M. agrestis from eight late Middle to Late Pleistocene archaeological and palaeontological sites in the Carpathian Basin, northern Hungary. The intra‐ and interspecific variations in both species can be related to climatic oscillations linked to the onset of the Eemian interglacial and the first phases of Marine Isotope Stage 5. The size of M. agrestis can be correlated with the presence/absence of relatively humid climatic and environmental conditions and of surface water resources (such as marshes and flooded areas). A possible immigration event of M. arvalis populations into the Carpathian Basin, also related to the Eemian interglacial, is also identified.

Morphotype and Multivariate Analysis of the Occlusal Pattern of the First Lower Molar in European and Asian Arvicoline Species (Rodentia, Microtus, Alexandromys)

“…Teeth with T6 and T7 fusion were found in fossil M. agrestis from Belarus (Ivanov, 2008) and south-eastern Serbia (Bogićević et al, 2012) with a frequency of 4.2 to 5.4 %. Teeth with such pattern are absent in recent M. agrestis from the highlands of the Ukrainian Carpathians (our data) and from Germany (Kapischke et al, 2009), as well as in fossil M. agrestis from Poland (Nadachowski, 1982) and northern Hungary (Luzi et al, 2019).…”

The Tien Shan vole (Microtus ilaeus; Rodentia: Cricetidae) as a new species in the Late Pleistocene of Europe

“…La/Li indices were calculated to quantify the degree of asymmetry between triangles T4 and T5 according to the method prescribed by Nadachowski ( 1984a ) and modified by Cuenca‐Bescós and Laplana ( 1995 ). This morphometric parameter is useful to distinguish vole species with an arvaloid morphology (e.g., Bogićević et al, 2012 ; Luzi & López‐García, 2019 ; Luzi et al, 2019 ; Nadachowski, 1984a , 1984b ).…”

“…In the Late Pleistocene of south‐eastern Europe, only two species of the arvalis group are recognized, namely, the common vole ( M . arvalis ), which has been detected in the Balkans and Pannonian Basin (e.g., Bogićević et al, 2017 ; Luzi et al, 2019 ; Mauch Lenardić, 2007 ; Popov, 2018 ) but is absent in the western and northern fringes of the Black Sea (Krokhmal & Rekovets, 2010 ; Petculescu & Ştiucă, 2008 ), and M . obscurus , which has been detected only in Crimea (Markova, 2011 ; Ridush et al, 2013 ).…”
