“…The different nesting site preferences of waterbirds may, therefore, be an important factor influencing the probability of depredation by mink. It seems that species which build their nests in the littoral zone of water bodies are at greatest risk of mink predation because mink are mostly active along a narrow strip of river or lake bank (Brzeziński, Marzec, & Żmihorski, ; Melero, Palazón, Revilla, Martelo, & Gosàlbez, ; Yamaguchi, Rushton, & Macdonald, ). Our results, as well as those of some former studies (e.g.…”

Aim: Theory predicts that the evolutionary adaptations of prey to reduce predator pressure often fail in confrontation with non-native predators; thus, their predation usually leads to sharp declines of prey populations. However, over time, prey can develop anti-predator adaptations, reduce predator impact and recover its population. We analyse the numerical response of multiple prey species to the impact of a non-native predator on a large spatiotemporal scale. Location: Poland.Methods: Long-term population dynamics of 13 waterbird species breeding in 123 sites were analysed with reference to the present and historical distribution of mink over 40 years. We rescaled the temporal waterbird dynamics to the time elapsed since the mink colonized each site. Results:The steepest waterbird declines were recorded up to 15 years after establishment of the mink population, and in that period, waterbird abundance averaged across the 13 studied species declined by 50% but certain species showed different patterns: the abundance of eight species declined linearly or nonlinearly, whereas the breeding populations of five other species did not change significantly. Over time, the abundance of some declining species increased slightly and tended to stabilize at a lower level. The temporal pattern of waterbird dynamics averaged across species correlated closely with temporal changes of mink density with a 4-year time-lag.A projection of the observed patterns shows that waterbird decline following the expansion of mink has the shape of a wave travelling from the north to the south of Poland. Main conclusions:We conclude that the impact of the invasive American mink should be considered an important factor affecting waterbird populations at a large geographical scale. The waterbird vulnerability to mink predation is species-specific, and over time the negative impact grows weak as mink population densities decline.

“…First, each species may specialize on distinct resources or respond in a different way to competitors [ 5 , 8 , 9 ]. Second, they may use resources or avoid enemies at different times [ 10 – 13 ], or thirdly, in different spaces [ 14 , 15 ]. Such ecological niche differentiation is often assumed to be the result of past competitive interactions between species (the ghost of competition past) [ 16 , 17 ].…”

Spatial Niche Segregation of Sympatric Stone Marten and Pine Marten – Avoidance of Competition or Selection of Optimal Habitat?

Coexistence of ecologically similar species relies on differences in one or more dimensions of their ecological niches, such as space, time and resources in diel and/or seasonal scales. However, niche differentiation may result from other mechanisms such as avoidance of high predation pressure, different adaptations or requirements of ecologically similar species. Stone marten (Martes foina) and pine marten (Martes martes) occur sympatrically over a large area in Central Europe and utilize similar habitats and food, therefore it is expected that their coexistence requires differentiation in at least one of their niche dimensions or the mechanisms through which these dimensions are used. To test this hypothesis, we used differences in the species activity patterns and habitat selection, estimated with a resource selection function (RSF), to predict the relative probability of occurrence of the two species within a large forest complex in the northern geographic range of the stone marten. Stone martens were significantly heavier, have a longer body and a better body condition than pine martens. We found weak evidence for temporal niche segregation between the species. Stone and pine martens were both primarily nocturnal, but pine martens were active more frequently during the day and significantly reduced the duration of activity during autumn-winter. Stone and pine martens utilized different habitats and almost completely separated their habitat niches. Stone marten strongly preferred developed areas and avoided meadows and coniferous or deciduous forests. Pine marten preferred deciduous forest and small patches covered by trees, and avoided developed areas and meadows. We conclude that complete habitat segregation of the two marten species facilitates sympatric coexistence in this area. However, spatial niche segregation between these species was more likely due to differences in adaptation to cold climate, avoidance of high predator pressure and/or food preferences by both species than competitive interaction between them.

“…DISCUSSION Spatio-temporal coexistence of American mink and several different animals, all in the carnivora order, offers an interesting point of view in terms of their comparison. Coexistence of American mink and European polecat (M.putorius) has been matter of numerous studies (Brzezinski et al, 2010). This appears to be possible in habitats offering sufficient food and shelter, but where these resources are less abundant, interspecific competition may lead to the decline and exclusion of the weaker competitor.…”

The mink is a strict carnivore and a seasonal breeder, which may be used as an experimental model for other carnivores. Using anatomical methods, 32 brains of the N. American mink were examined. It was found that the brain consists of four ventricles. Also, it was noted that the posterior horn was missing and that the olfactory recess was present in the lateral ventricle, a large-size interthalamic connection was present in the third ventricle, and a flat, necklace like bottom in the fourth ventricle. Only recently, the ins and outs of the mink's anatomical structure have begun to absorb the attention of anatomists. Apparently, it is related to the fact that fury animals, among them the mink, are being domesticated. For this reason and because of easy access to the material, the purpose of brain dissection is to familiarize with the three dimensional structure of the brain and teach one of the great methods of studying the brain: looking at its structure.
