“…At an intraspecific level, north‐central and southern populations may be discriminated by the morphology of the first lower molar. Interestingly, the same pattern is also known at an interspecific level within the subgenus Microtus ( Terricola ) between northern and southern species in western Europe …”

Savi's pine vole (Microtus savii) is a rodent species of the Cricetidae family, inhabiting southern European agroecosystems. It is considered to be the main cause of rodent-attributed damage in Italy. To achieve an effective management, detailed knowledge of this species is needed. However, the available information about this species is fragmentary and incomplete. In this paper, the existing knowledge of Savi's pine vole taxonomy, reproduction, population dynamics, habitat and food preferences is reviewed in order to organise available information and identify priority areas of future research. Some of the changes in farming practices that have occurred in recent decades may have increased the impact of Savi's pine vole populations in crop fields. To manage this pest species effectively, an integrated strategy is recommended (involving habitat management, trapping and, when appropriate, the use of rodenticides). The apparent lack of cyclical population outbreaks and the relatively small litter size and long gestation and interpartum period of this species suggest that it could be more manageable than other vole species, while its strict herbivorous diet, stable population size in open habitats and wide distribution seem to indicate it as an ideal model species for risk assessment studies.

“…Indeed, not just molar proportions but also tooth pattern began to be highly specialized (prismatic pattern and increasing highcrown molars) as food became very abrasive. In comparison with the pattern found in other groups of rodents during quaternary time (i.e., bunodont form), the prismatic pattern of vole molars could provide a better adaptation to the abrasive vegetation found in steppes and meadows in which voles and lemmings usually live (Nadachowski 1984;Marchand et al 2003;Montuire and Brunet-Lecomte 2004;Nappi et al 2006). Nevertheless, essentially three features can be distinguished on the structure of tooth row: (1) molar proportions, (2) occlusal tooth design and enamel structure (e.g., bunodont, lophodont, prismatic: see von Koenisgwald 1980Koenisgwald , 1982Janis 1995Janis , 2000Evans et al 2005Evans et al , 2007Lucas et al 2008), and (3) crown growth (hypsodonty versus brachyodonty; see Jernvall et al 2000b;Jernvall and Fortelius 2002;Fortelius et al 2003;MacFadden 2005).…”

“…Recently, dental phenotypic variability has been investigated with character measurements on both extant and fossil populations to detect the causal effects leading to arvicoline diversification (Nadachowski 1984; Marchand et al 2003; Montuire and Brunet‐Lecomte 2004; Nappi et al 2006). We project arvicoline fossil data onto the developmental model of Kavanagh et al (2007).…”

Evolution of Mammal Tooth Patterns: New Insights From a Developmental Prediction Model

The study of mammalian evolution is often based on insights into the evolution of teeth. Developmental studies may attempt to address the mechanisms that guide evolutionary changes. One example is the new developmental model proposed by Kavanagh et al. (2007), which provides a high-level testable model to predict mammalian tooth evolution. It is constructed on an inhibitory cascade model based on a dynamic balance of activators and inhibitors, regulating differences in molar size along the lower dental row. Nevertheless, molar sizes in some mammals differ from this inhibitory cascade model, in particular in voles. The aim of this study is to point out arvicoline and murine differences within this model and to suggest an alternative model. Here we demonstrate that the inhibitory cascade is not followed, due to the arvicoline's greatly elongated first lower molar. We broaden the scope of the macroevolutionary model by projecting a time scale onto the developmental model. We demonstrate that arvicoline evolution is rather characterized by a large gap from the oldest vole to more recent genera, with the rapid acquisition of a large first lower molar contemporaneous to their radiation. Our study provides alternative evolutionary hypotheses for mammals with different trajectories of development.K E Y W O R D S : Arvicolinae, evo-devo, evolution, inhibitory cascade, rodents.

“…For instance, in a fossil series of the arvicoline Terricola savii, the length-to-width ratio increased over time [23] and also varies among contemporary populations [55] indicating a length-width evolutionary allometry deviating from isometry (i.e. b = 1).…”

The allometric-constraint hypothesis states that evolutionary divergence of morphological traits is restricted by integrated growth regulation. In this study, we test this hypothesis on a time-calibrated and well-documented palaeontological sequence of dental measurements on the Pleistocene arvicoline rodent species Mimomys savini from the Iberian Peninsula. Based on 507 specimens representing nine populations regularly spaced over 600 000 years, we compare static (within-population) and evolutionary (among-population) allometric slopes between the width and the length of the first lower molar. We find that the static allometric slope remains evolutionary stable and predicts the evolutionary allometry quite well. These results support the hypothesis that the macroevolutionary divergence of molar traits is constrained by static allometric relationships.
