Agrobiont spider species are well adapted to arable systems, which have fairly uniform vegetation structure and pest assemblages over continent-wide areas. We wanted to study, whether agrobiont spider subassemblages and the life history of the most prominent agrobiont, Pardosa agrestis, show any regional variation within Hungary, where only modest climatic differences exist between the NW and S...

Predation by specialist mammalian predators has been hypothesized to be the primary cause of multi-annual density fluctuations (‘population cycles’) in voles. Using a series of replicated field experiments, Isla Graham and Xavier Lambin have now shown that specialist mammalian predators are neither necessary nor sufficient to drive field vole Microtus agrestis population cycles. These findings ...

Electrical stimulation of the anterior hypothalamus of the vole, Microtus agrestis, usually results in ovulation, whereas stimulation of areas in the posterior hypothalamus do not. Ovulation can also be elicited by injections of sheep median-eminence extracts, and by preparations ofsheep luteinizing hormone. Observations on the number of corpora lutea formed, and ripe Graafian follicles remaini...

The heligmonellid nematode Carolinensis minutus (Dujardin, 1845) Travassos, 1937 is recorded for the first time in Microtus agrestis (Linnaeus, 1761) United Kingdom. Small heligmosomoid specimens were recovered from a M. vole inhabiting mole ( Talpa europaea Linnaeus, 1758) tunnels mid Wales. identity of these was confirmed as C. by >99% nucleotide with internally transcribed spacer (ITS) 1 ...

The genus Microtus has high karyotypic diversity. The existence of notable differences in the length of its sex chromosomes contributes to this variation. Variations in size are attributed to the enlargement of their heterochromatin content, which is of such magnitude in some species that they are referred to as "giant sex chromosomes". Here, we perform an intra- and interspecific analysis of t...
