ECOLOGICAL-NICHE FACTOR ANALYSIS: HOW TO COMPUTE HABITAT-SUITABILITY MAPS WITHOUT ABSENCE DATA?
We propose a multivariate approach to the study of geographic species dis- tribution which does not require absence data. Building on Hutchinson's concept of the ecological niche, this factorExpand
Molecular phylogeny and evolution of Sorex shrews (Soricidae: insectivora) inferred from mitochondrial DNA sequence data.
TLDR
The molecular data suggest that Sorex comprises two major monophyletic lineages, one restricted mostly to the New World and one with a primarily Palearctic distribution, and estimates from the fossil record greatly underestimate divergence dates among SoreX taxa. Expand
Origin and evolution of homologous repeated sequences in the mitochondrial DNA control region of shrews.
TLDR
The pattern of sequence and length variation within and between species, together with the capability of the arrays to form stable secondary structures, suggests that the dominant mechanism involved in the evolution of these arrays in unidirectional replication slippage is related to asymmetry in the replication of each strand of the mtDNA molecule. Expand
Is the Gibraltar Strait a barrier to gene flow for the bat Myotis myotis (Chiroptera: Vespertilionidae)?
TLDR
Variability at 600 bp of a mitochondrial gene confirms the existence of two genetically distinct and perfectly segregating clades, which diverged several million years ago and suggests that the North African clade is possibly a distinct taxon warranting full species rank. Expand
MICROSATELLITES CAN BE MISLEADING: AN EMPIRICAL AND SIMULATION STUDY
TLDR
Estimates of genetic differentiation in a contact zone between two chromosome races of the common shrew based on 10 autosomal microsatellites, a newly developed Y‐chromosome microsatellite, and mitochondrial DNA show that all gene exchange between races is mediated by females, and the absence of male‐mediated gene flow most likely results from male hybrid sterility.

CHROMOSOMAL VERSUS MITOCHONDRIAL DNA EVOLUTION: TRACKING THE EVOLUTIONARY HISTORY OF THE SOUTHWESTERN EUROPEAN POPULATIONS OF THE SOREX ARANEUS GROUP (MAMMALIA, INSECTIVORA)
TLDR
The shrews of the Sorex araneus group have undergone a spectacular chromosome evolution, and available data suggest that the impressive chromosome polymorphism of this group is quite a recent phenomenon. Expand
Trophic resource partitioning and competition between the two sibling bat species Myotis myotis and Myotis blythii
TLDR
It is suggested that active interspecific competition is not the underlying mechanism responsible for the niche partitioning which is currently observed between M. myotis and M. blythii, and clearcut partitioning of resources may allow the stable, intimate coexistence observed under sympatric conditions. Expand
The List of the Chromosome Races of the Common Shrew (Sorex Araneus)
The list of chromosome races of the common shrew (Sorex araneus) was compiled, the vast literature has been scrutinized, and unpublished data have been added. Altogether, 50 chromosome races could beExpand
The list of the chromosome races of the common shrew Sorex araneus (updated 2002)
TLDR
L'ISACC (International Sorex araneus Cytogenetics Committee) a publie en 1996 la premiere liste de races chromosomiques de S. Araneus, qui comprend actuellement 68 races. Expand
Threatened rodents in Europe: species status and some suggestions for conservation strategies
A definition of a chromosome race of the common shrew (Sorex araneus) is proposed, and supplemented by rules and conventions to name, group and describe the races.
