sea mink extinction date

The last substantiated report has led to an estimated extinction date of around 1860, [3] although a specimen was reported as sold to a fur-buyer in Maine in 1880. Hardy (1903) seems to have been the 1st to connect the archaeological specimens to accounts by locals of a large, reddish-furred mink with a distinctive odor and a fatter body than that of the American mink (Manville 1966; Seton 1926). (2004) and Van Valkenburgh and Wayne (1994), the length of the carnassial tooth was used as an estimate of body size. Possibly the first description of this species was made by Sir Humphrey Gilbert The highly prized fur of the Sea Mink caused hunters to kill every single last one in order to retrieve the fur and make a profit out of it. The mean estimate of divergence between N. macrodon and N. vison (0.43) was comparable to the mean estimate of divergence in 28 regressions of 2 different species of Mustela or Neovison (0.41, range 0.14–0.79). Sexual dimorphism in dental proportions appears to contribute little to the perceived differences between American mink and sea mink (Fig. In both N. macrodon and the archaeological sample of N. vison, the mandibles disproportionately belonged to larger individuals, presumably males. The 1st principal component analysis axis, representing 91% of the variation, was interpreted as representing size differences among the various species, and the remaining axes as reflecting differences in shape. "The Extinct Sea Mink, with Taxonomic Notes. Thus, although no pairs of archaeological maxillaries and mandibles used in this study were known to belong to the same individual, the sizes of the maxillaries relative to the mandibles could be estimated. The sea mink was hunted to extinction in the latter part of the 19th century, even before it was taxonomically described or scientifically studied (Black et al. 2000; Mead and Spiess 2001). ScienceDaily, 5 October 2020. Pediatric Mock Exam 1; Pediatric Sonography Mock Exam 2; Pediatric Sonography Review; NEOUS Fall 2018 Symposium; NEOUS Fall 2019 Symposium The ranging behavior of the sea mink was probably similar to that of its relatives, and its mating system was probably polygynan-drous, as in Mustela and N. vison. A) Histogram of ml length, a standard proxy for body size, in the Turner Farm mink mandibles. Most sea mink remains are unearthed on the coast of Maine. It was described as a "fish" that looked superficially like a monk. Archaeological mandibular specimens.—In the Carnivora, the length of the lower 1st molar (ml; Fig. American mink. The sea mink (Neovison macrodon (Prentiss, 1903): Mustelinae) was an unusual late-Cenozoic example of an organism that had rapidly evolved toward a marine niche. The sea mink (Neovison macrodon (Prentiss, 1903)) inhabited the shores of New England and possibly the Canadian Maritime Provinces. Even when fossils are found, inferences about the adaptations and behavioral ecology of extinct species are largely based on studies of extant species. Because the resolution of the fossil record is low, little is understood about the evolution of longer-established marine lineages such as the Cetacea and the Pinnipedia. Analyses of covariance or t-tests also were performed on selected mandibular measurements and measurement ratios to analyze differences in these measurements adjusted for body size and allometric scaling between sea mink and American mink (Table 2). Another measurement taken on some species, N1MP = distance between the apexes of the protoconid and metaconid cusps, did not exist in the sea mink and is not shown. [4][13][20] In 1929, Ernest Thompson Seton, a wildlife artist, concluded that the probable dimensions for this animal are 91.4 centimeters (36 in) from head to tail, with the tail being 25.4 centimeters (10 in) long. PNAS , 2020 DOI: 10.1073/pnas.2009397117 Cite This Page : The only known remains are bone fragments unearthed in Native American shell middens. [4], The taxonomy of the minks was revised in 2000, resulting in the formation of a new genus, Neovison, which includes only the sea mink and the American mink. 1998; Campbell 1988; Hollister 1965; Seton 1926; Youngman 1989). 3A).

A previous caliper and camera lucida analysis of the same dental measurements (Popowics 2003) produced nearly identical measures of N. vison (Pearson's product-moment correlation coefficient r > 0.99). Musteloids occupy nearly all continents, inhabit latitudes from the arctic to the sub-antarctic, and the superfamily is arguably the most species-rich in the Carnivora. Like other weasels, the sea mink was probably polygynandrous, with both sexes mating with multiple individuals. The youngest direct date of 2,720–2,350 calendar years B.P., combined with the absence of Chendytesbones from hundreds of late Holocene sites, suggests that the species was extinct by ≈2,400 years ago. One hundred mink mandibular samples and 11 mink maxillary samples were sufficiently well preserved for use in this analysis ( Appendix I). ... (1961) Former range of the sea mink. (2000) obtained individuals of N. vison from nearly the full extent of this species' range, including Alaska, Pacific offshore islands, and the east coast of North America, my study only incorporated specimens from the continental United States and southern Canada (subspecies energumenos, letifera, mink, and vison). [13], Fur traders who hunted it gave the sea mink various names, including water marten, red otter, and fisher cat. Most recently, Mead et al. The last two recorded kills of a sea mink were made in Maine in 1880 near Jonesport, Maine, and Campobello Island, New Brunswick, in 1894,[14] although the 1894 kill is speculated to be of large American minks. Based on comparisons with American mink, it appears likely that the archaeological specimens included primarily N. macrodon but also N. vison. Acronyms of measurements are as defined in Fig. Type locality “Brook-lin, Hancock County, Maine.”. [4], Like other minks, individual sea minks may have maintained home ranges, and since the males were larger and required more food, males would have had larger territorial claims. I also thank J. Monge, W. Bock, C. Long, S. Bell, S. Sealfon, Y. Ge, J. Altmann, and A. Spiess for advice and comments on the manuscript. However, the sea otter (Enhydra lutris) is a specialist feeder on shelled invertebrates and possesses particularly large crushing surfaces (Popowics 2003). (2000). It was nearly twice as large as the common American mink, and had a slightly redder hue, so was highly prized by hunters. Sea Mink. The latter is most likely, as no other mink remains have been discovered between Casco Bay in Maine and southeastern Massachusetts. [4], As marine mammal species often play a large part in their ecosystems, it is possible that the sea mink was an important intertidal predator. [16] Mead concluded that only American minks inhabited the mainland and that sea minks were restricted to islands off the coast. Because of these attributes, the Musteloidea is a highly suitable lineage for paleontological studies of mac-roevolutionary niche shift. [13], The type specimen was collected by Prentiss and Frederick True, a biologist, in 1897 in Brooklin, Maine, the remains of which consist of a maxilla, parts of the nasal bone, and the palate. Department of Ecology and Evolutionary Biology, Princeton University, Princeton, NJ 08544, USA. This is an incomplete list of extinct animals of North America.This list covers only extinctions from the Holocene epoch, a geological period that extends from the present day back to about 10,000 radiocarbon years, approximately 11,430 ± 130 calendar years BP (between 9560 and 9300 BC). 1991). Little is known about this species as it was exterminated from its native range before any scientists could analyze it. This last morphological character may have contributed to the decision of Prentiss (1903) to name the sea mink Lutreola macrodon. The sea mink was a type of mink that was hunted to extinction for its fur. It may have exhibited behavior similar to the American mink, in that it probably maintained home ranges, was polygynandrous, and had a similar diet, though more seaward-oriented. The terrestrial lineages are adapted for following their prey into many types of environments, including burrows and tree canopies. Most sea mink remains, nearly all of them skull fragments, have come from shell middens, but a complete specimen has never been found. In contrast, only one native land mammal in North America - the sea mink - became extinct during the same time period. Because otters (Lutrinae) and Mustela species generally grouped together and the subspecies of N. vison clustered quite tightly, these axes appeared to provide a reasonable estimate of phylogenetic relatedness. The teeth are all present on the right side of the palate, and the left side consists of the incisors and one premolar. 3D). To test the reliability of the measurements, triplicate analyses of the same photographs were performed days or weeks apart. The Manhattan distance of the residuals obtained was small, suggesting that any bias in the sex composition of the sample of N. macrodon was insufficient to account for the differences observed in the regression of N. macrodon against N. vison (Fig. For principal component analysis, comparisons were made with published measurements of 6 specimens representing N. vison and 78 specimens representing 13 additional musteloid species (Popowics 2003). Sexual dimorphism in each measurement in the American mink. "Proceedings of the United States National Museum. The oligobunids went extinct around 10 million years ago, possibly outcompeted by a new wave of modern mustelids that evolved in Asia and spread into North America. The Manhattan distances of the residuals for the largest sea mink and the several subspecies of American mink (range 0.66–1.29) were greater than the Manhattan distances for all combinations of subspecies of N. vison in this analysis (range 0.13–0.46). (2000). The following museum curators graciously provided assistance during visits to collections: S. Bell, J. Galkin, and E. Westwig, American Museum of Natural History; R. Lewis, B. Bourque, and P.

Content retrieved from Wikipedia, and managed by the Marine Mammal Science Education Committee. But it didn’t look like any other mustelid. Thus, in agreement with both Nowak (1999) and Wozencraft (2005), this study supports recognition of the sea mink (N. macrodon) as a species separate from N. vison. D&D Beyond The sea mink's wider carnassial teeth and blunter carnassial blades suggest that they crushed hard shells more often than did the teeth of the American mink. A.. Thom M. D. Harrington L. A. Macdonald D. W.. Oxford University Press is a department of the University of Oxford. [8] A study conducted in 2000 by Mead et al. 1.) This was attributed to sexual selection acting on the canines, although males do feed on somewhat larger prey. [16] The sea mink may have reached that area by traveling up rivers, or may have been brought there by Native Americans. A larger relative of the American mink (N. vison), it inhabited the shores of New England and possibly the Canadian Maritime Provinces until it was hunted to extinction in the 19th century. Last day 1 week 1 month all. These results suggest that all the maxillary specimens taken from the archaeological site were N. macrodon. The largest of the minks, the sea mink was more desirable to fur traders and became extinct in the late 19th or early 20th century. It was probably found on the New England coast and the Maritime Provinces, though its range may have stretched further south during the last glacial period. In the principal component analyses, these measurements were used to provide additional groups for comparison. It is established that several lineages of Mustelinae, especially Neovison, evolved aquatic adaptations independently of the otters (Lutrinae). You can make this change permanent at your preferences.. Gallery For most analyses, especially those of average trends in the evolution of several dental features, measurements were converted to their natural logarithms (In) to linearize the allometry equation (Jolicoeur and Mosimann 1960). Although many of the sex differences in these dental proportions approached or exceeded significance (see “Results” and Table 1), the actual size of the difference was slight. Axis 1, which was interpreted as representing size differences, described 91% of the variation among the musteloid species. Likewise, their larger size may have allowed the males to target larger prey than the females, and they may have had to defend females during mating seasons. 3E. The most divergent populations within a single species may still be much less different than separate species, a situation that is probably the case for N. vison. Fandom Apps Take your favorite fandoms with you and never miss a beat. Axis 3 represented 27% of the remaining variation, and axis 4 represented 7.6%. Screenshots of Neovison macrodon in ImageJ illustrating the linear and area measurements that were taken based on a protocol in Popowics (2003) for quantifying shearing and crushing tooth surfaces. Despite the small sample size for maxillaries of N. macrodon, highly significant and size-independent differences were found in comparisons of N. vison and N. macrodon (Table 2). (2004) argue that they should not be grouped together because their divergence is too great. 1998; Waters and Ray 1961). 1998; Campbell 1988; Hollister 1965; Seton 1926; Youngman 1989). v. energumenos (6): AMNH 40858 (male); AMNH 1460, 24421, 63983, 120592, 121551 (sex unknown). They were also more robust and broader in appearance. But it didn’t look like any other mustelid. To compare all 7 maxillary characters of sea mink with those of the entire musteloid data set, average measurements for all musteloid species were analyzed using principal component analysis. N. vison eats both aquatic and terrestrial prey, primarily vertebrates, but its diet also includes invertebrates. 2004; Van Valkenburgh and Wayne 1994).

It is interesting, however, that sexual dimorphism virtually disappeared in this analysis of postcanine dental characters that are implicated primarily in feeding ecology rather than other characters that are implicated in both feeding ecology and sexual selection. I read a very depressing book called “The Sea of Slaughter” by Farley Mowat, and that had a short chapter about the way the sea mink was hounded to extinction for its pelt. NS = nonsignificant, int = intercept. The sum of the talonid and m2 areas, a measure of molar crushing surface, was slightly but significantly smaller in the sea mink when adjusted for the length of the lower 1st molar (ANCOVA, F = 642.8, d.f = 2, 68, P < 0.02), even though the absolute size of this measurement was larger. If it was hiding, it was smoked out and suffocated. Vermeij listed a date of “about 1900.” Monachus tropicalis : Knudtson ( 67 ) noted that the last authenticated sighting was in 1952 on Serranilla Bank in the western Caribbean. 4), representing 7.6% of the non-size-related variation. ; 10 = Aonyx capensis; 11 = Arctonyx collaris; 12 = Eira barbara; 13 = Gulo gulo; 14 = Ictonyx striatus; 15 = Lontra canadensis; 16 = Martes americana; 17 = Meles meles; 18 = Mellivora capensis; 19 = Mephitis mephitis; 20 = Mydaus javanensis; 21 = Taxidea taxus. You will need to be logged in to be able to change category appearance. (2000) reported the existence of numerous mink osteological specimens, including postcranial remains, in the Maine State Museum. Although land-to-sea evolutionary transitions are extremely uncommon, the sea mink is a late-Cenozoic example of a species that recently and rapidly became marine. The taxa measured for this study included the 4 American mink subspecies as well as 10 additional species. The detailed measurements of the mustelid postcanine dentition (described by Popowics [2003]) and their corresponding relationship to dietary niche space have not been used previously to test whether the 2 sexes function as different morphospecies. The unregulated fur trade eventually led to its extinction, which is thought to have occurred between 1860 and 1920. The width-to-length ratio of the lower 1st molar, which showed no significant correlation with the length of the molar in either the 50 largest sea mink (r = 0.041, P = 0.78) or the museum American mink (r = −0.0093, P = 0.95), was significantly larger in the largest sea mink (t = −4.21, d.f. It was valuable because of its large size so the pelt fetched a higher price and it was actively sought by trappers. My analysis suggests the 2 sexes function as 1 morphospecies, at least for these characters in American mink. Fur traders mad… The unregulated fur trade eventually led to its extinction, which is thought to have occurred between 1860 and 1920. 2000), and the 2 species are usually placed in the same subgenus Putorius. Plesiogulo sp. The ml in the larger archaeological group, which contained 75 specimens, was larger than any N. vison measured (9.27–10.73 mm). Specimens are known from about 5,000 to 150 years ago. Specimens are known from about 5,000 to 150 years ago. Within extant Musteloidea, the otters (Lutrinae) are some of the most dentally specialized for crushing. Skeletal and skin specimens were not collected by zoologists, but the former are known from Native American archaeological sites. The morphological distance between N. macrodon and N. vison, as assessed by dental proportions, was comparable to the distance between pairs of known musteloid species in the same subfamily. 3B and 3C). Pteronura brasiliensis (10).—AMNH 30191, 71859, 74431, 74432, 214394 (female); AMNH 73587, 91711, 91712, 93121, 98594 (male). Remains of toad sculpins and ocean pout were the most common around their dens, and garden banded snails were also reported to have been part of their diet. Unlike the anterior dentition, which is used to obtain food and also may be implicated in sexual selection (Thom et al. [4], Since the sea mink has only been described by fragmentary remains, its appearance and behaviors are not well-documented. The sea mink is thought to have been exterminated around about 1894 thanks to constant trapping for their fur. Accounts from Native Americans in the New England/Atlantic Canadian regions reported that the sea mink had a fatter body than the American mink. Although pairs of species within the Lutrinae and genus Mustela showed divergence comparable to that of N. vison and N. macrodon, the dental proportions of male and female N. vison and of the several N. vison subspecies were nearly identical. Mink and river otters enter the water largely to forage, and the behavioral ecology of these high-trophic-level predators is greatly affected by food availability (Dunstone 1993; Kruuk 1995). Point numbers correspond to the measurements described in Fig. The differences between the sea mink and American mink measurements (Manhattan distance of residuals, X̄ = 0.92) were comparable to or greater than the differences between species pairs in the Mustelinae (Manhattan distance of residuals, X̄ = 0.66, range 0.25–1.45; Fig. Its actual size is speculative, based largely on tooth remains. 2A and 2B). The nasal bone has an abrupter ascension, and the carnassial teeth make a more acute angle with the gums than those of the common mink (N. v. [13] Their seafood-oriented diet may have increased their size. The sea mink was first described as Lutreola macrodon, distinct from the American mink, by Daniel Webster Prentiss, a medical doctor and ornithologist, in 1903 after it became extinct. Land-to-sea evolutionary transitions are of particular interest because of the drastically different adaptive requirements for surviving in terrestrial and marine environments (e.g., see Bajpai and Gingerich 1998). ... (1961) Former range of the sea mink. To test the hypothesis that the differences in dental proportions between the largest N. macrodon and the museum N. vison were due to sexual dimorphism rather than evolutionary divergence, vectors representing the geometric means of male and female N. vison were compared (Fig. "Archaeological records of the extinct sea mink, "The extinct mink from the Maine shell heaps", Subscription to the Marine Mammal Science journal. [14][15] The bones of a specimen unearthed in Middleboro, Massachusetts, were dated to be around 4,300±300 years old, 19 kilometers (12 mi) from salt water. Mandibles (100): MSM 2991, 29916, 29921, 29923, 29924, 29928, 29931, 29942, 29944, 29947, 29948, 29952, 29953, 29955, 29970, 29971, 29974, 29975, 29979, 29982, 29983, 29985, 29986, 29993, 29994 (2 individuals), 29995, 29996, 299100, 299104, 299105, 299106, 299115, 299117, 299119, 299120, 299122, 299124, 299287, 299288 (2 individuals), 299290, 299291, 299294, 299295, 299297, 299298, 299300, 299310, 299314, 299315, 299319 (2 individuals), 299321, 299322, 299324, 299331 (3 individuals), 299334, 299337, 299339, 299344, 299346 (2 individuals), 299347, 299350, 299354 (3 individuals), 299361, 299362, 299369, 299374, 299377, 299379, 299380, 299381, 299482, 299488, 299490, 299492, 299505, 299508, 299517 (2 individuals), 299526, 299532, 299544, 299557, 299565, 299566, 299568, 299573, 299580, 299582, 299583, 299584 (2 individuals), 299587. For example, the island fox (Urocyon littoralis) was isolated on California's Channel Islands in this time period and is considered a separate species from the gray fox (Urocyon einereoargenteus—Wayne et al. In many instances, a sufficiently large sample size could only be obtained by incorporating individuals of unidentified sex ( Appendix I). [15] Their large size was probably in response to their coastal environment, as the largest extant subspecies of American mink, the Alaskan mink (N. v. nesolestes), inhabits the Alexander Archipelago in Alaska, an area with a habitat similar to the Gulf of Maine. 2000), Kurtén and Anderson (1980) suggested it is conspecific with the allopatric steppe polecat (Mustela eversmanii) which can interbreed with both M. nigripes and the European polecat (Mustela putorius) in captivity. ScienceDaily. They had a long, bushy tail and the body was covered with a reddish-brown coarser coat. The dentition of N. vison, although similar to that of rodent-specialist mustelids such as Mustela erminea and M. frenata, shows larger crushing surfaces. [6], During the last glacial period, ending 12,000 years ago, the sea mink's range may have extended south of the Gulf of Maine. A ruler included in each image was positioned level with and parallel to the alveolar rim of the carnassial tooth. Their body was flatter than that of the American mink. The regression of the most geographically separated subspecies pair, N. v. energumenos of western North America and N. v. mink of eastern North America, is shown in Fig. Neovison macrodon Baryshnikov and Abramov, 1997:1399– 1410.

Specimens were included in the analysis if some or all of the relevant teeth were preserved, there was sufficiently little breakage for tooth proportions to be reliably determined, and there was sufficiently little wear for distances between the apexes of tooth cusps to be measured reliably. Those who argue that the sea mink was a subspecies often refer to it as Neovison vison macrodon. If significant (P < 0.1), the differences between allometric scaling of males and females are listed. Although the lower layers of the shell midden appear to have included large specimens of N. macrodon, remains of N. macrodon older than about 5,000 years have not been described. Axes 3 and 4 from a principal component analysis of all 7 maxillary measurements from 14 subspecies, species, and genera analyzed in this study, including measurements from 13 additional species reported in Popowics (2003). Other species include: 1 = Mustela erminea; 2 = M.frenata; 3 = M. nigripes; 4 = M. putorius; 5 = Aonyx cinerea; 6 = Lutra lutra; 7= Hydrictis maculicollis; 8 = Pteronura brasiliensis; 9 = Plesiogulo sp. [9] Graham challenged that hypothesis, stating that it is unlikely that all sea mink specimens originate from one population. 6 hours 12 hours 1 day 3 days all. Six individuals from each of the following species also were measured by Popowics (2003): Aonyx capensis, Arctonyx collaris, Eira barbara, Enhydra lutris, Gulo gulo, Ictonyx striatus, Lontra canadensis, Martes americana, Meles meles, Mellivora capensis, Mephitis mephitis, Mydaus javanensis, and Taxidea taxus. = 75.54, P = 6.9 × 10−5). Each specimen was regressed against both the mean N. vison and the mean of the 50 largest specimens of N. macrodon, as determined by carnassial length. Other carnivoran species are thought to have diverged as recently as 10,000–16,000 years ago. N. v. vison (18): AMNH 5340, 8211, 8212, 9985 (female); AMNH 5339, 8213, 8215, 9986, 22749 (male); AMNH 11470–11472, 77887, 128507–128510, 128512 (sex unknown). He suggested assigning all the archaeological specimens analyzed by Mead et al. Manville, Richard H. 1966. Except for the otters, it was probably the most aquatic member of the Musteloidea. The hypothesis that the sea mink showed dental divergence from N. vison, an indication of systematic and ecological distinctness, was tested on 111 dentally mature mink specimens originally collected from the Turner Farm archaeological site (Penobscot Bay, Maine). For example, N. macrodon possessed broader upper and lower carnassial teeth and shorter upper carnassial blades, independently of body size and allometric scaling. Evaluation of N. macrodon divergence.—Principal component analysis was used to explore relationships among the dental measurements in multiple species of Musteloidea. The exception was N. v. letifera, for which the oldest available specimens date to the 1950s. These results are consistent with previous studies of American mink and other carnivorans, in that the carnassials showed significant but slight sexual dimorphism in relative proportions (e.g., Dayan and Simberloff 1996; Holmes and Powell 1994; Lynch and Hayden 1995; Meiri et al. Specimens are known from about 5,000 to 150 years ago. Extant taxa viewed included 4 subspecies of N. vison, 4 species of the related genus Mustela, and 5 species in the Lutrinae. The Turner Farm specimens are presently housed at the Maine State Museum in Augusta, Maine. The highly prized fur of the Sea Mink caused hunters to kill every single last one in order to retrieve the fur and make a profit out of it. Animals that became extinct in the last 2,000 years go in this category. However, this was not truly a marine mammal Science Education Committee 1860 and 1920 independently of the relevant were.
