“…Such phenomenon could be invoked to explain the skewed sex ratio favoring pine marten males at Cova Fosca. However, we doubt that this could have been the case for, in contrast to the marked size differences that males and females of the Genera Neovison and Mustela exhibit, the sexual size dimorphism in the Genus Martes is far more attenuated, rendering it more unlikely the asymmetrical sexual displacement response that Barrientos (2015) described.…”

“…Thus, in addition to traditional explanations invoking habitat exclusion and trophic competition, the vulnerability of the native females in the light of aggressive behaviors of the invading males has been recently reported for carnivores. Barrientos (2015) noted that, after establishing contact with populations of the American mink (Neovison vison Schreber, 1777), populations of the European polecat (Mustela putorius Linnaeus, 1758) exhibited a biased sex ratio disfavoring females. A steady reduction of females, on which the productivity of the population resides, would become a critical factor dictating an eventual local demise of the native species.…”

a b s t r a c tZooarchaeological and palaeontological records indicate that whereas the pine marten (Martes martes, L.) constitutes a genuine element of the European fauna, the beech marten (Martes foina E.) is a recent colonizer whose invasion was fostered by the spread of the Neolithic economies. In this paper: (1) we provide the first direct radiocarbon date for the appearance of the beech marten in the Iberian Peninsula and Europe, (2) assess the evolution of the abundances of the two species in the eastern Iberian site of Cova Fosca (13,360e4522 cal BC), and (3) explore the causes that may have played a role in the expansion of the beech marten and the retreat of the pine marten to the northern fringe of the Iberian Peninsula. Our study suggests that whereas the beech marten might have benefited from landscape transformations that the Neolithic agropastoral communities fostered, hunting pressure along with a combination of natural and anthropic landscape changes that took place in eastern Iberia after the onset of the Neolithic (ca. 5600 cal BC onwards) may have sealed the fate of the pine marten in the region.

“…The authors concluded that more male mink may be born in the wild, which is also suggested by Zwiernik et al (2008) and Schüttler et al (2010). The wild population of the European polecat has also been reported to consist of more males than females (Brzesiński et al, 1992;Barrientos, 2015).…”

Abstract. The aim of the study was to analyse the sex ratio of American mink litters in relation to dam's age, gestation length, and time interval between the first and second mating. The observations were carried out on a mink farm located in northern Poland. The analysis involved litters of 207 females, aged 1 (n=107) and 2 years (n=100), which successfully raised all the born kits. The sex of the offspring was identified on weaning. The kits were assigned to groups according to their dam's gestation length, mating date, and first-to-second mating interval. It was found that female kits quantitatively predominated over male offspring. Longer pregnancies, delayed mating time, and greater interval between the first and second mating was accompanied by a higher number of female births in relation to male births.

“…Polecats have spread into central, eastern, and southern England, although they have not yet recolonised parts of northern England or Scotland (Croose ). In Belarus, American mink out‐compete female polecats and exclude them from aquatic habitats (Sidorovich et al ), and, throughout their European range, the proportion of reproductive females in the polecat population is lower where they co‐occur with mink (Barrientos ). There is no evidence that the recovery of polecats in Great Britain has been hindered by the presence of mink (see, e.g.…”

Current status of American mink Neovison vison in Great Britain: a review of the evidence for a population decline

The American mink Neovison vison in Great Britain is an invasive alien species, with significant impacts on native prey species. There have been suggestions that populations of mink in Britain have declined since the 1990s. Three nationwide data sets include data on mink distribution and abundance. Scat surveys and the National Game Bag Census suggest population declines, but the latter does not take account of survey effort (which may also have declined) and the former is misleading because there is evidence that mink change their marking behaviour in the presence of otters Lutra lutra. National Biodiversity Network data suggest an increase in mink numbers, but this can be explained by a concomitant increase in mammal recording. Although intra‐guild competition between invasive mink and native otters is likely, there is no evidence that otters have caused a decline in mink numbers. There is little information on the impact of disease, or exposure to rodenticides, on wild mink – both warrant further attention. Eradication efforts can have an impact on mink populations, but currently neither implementation nor monitoring is sufficient to generate effects throughout Great Britain or to assess the impact of cumulative local and regional efforts. We conclude that it is not possible, on the basis of currently available data for Great Britain, to ascertain the status of mink or assess the underlying trend in their population. We stress the importance of collaboration, coordination, and record keeping (and sharing) in future, proper interpretation of existing data, and the use of alternative data sources. We call for greater, and better, effort in both mink management and monitoring of management in Great Britain.
