A survey of the morphology of pads within the Viverridae has been related to locomotion, ecology, ethology and to other morphological features. Species with digitigrade hind foot are lacking metatarsal pads, have an elongated pes, a short tail, and non retractile claws. They are terrestrial and their fur is spotted. Species with plantigrade hind foot, have broad and long metatarsal pads, which form a bare sole. They have retractile claws, a long tail, and fur with few markings or are one-coloured. They are arboreal and most of them are omnivorous or fruit-eaters. The genets and Poiana are intermediate forms because they have digitigrade feet, but possess long metatarsal pads, retractile claws, a long tail and spotted coat. However, some of them are close to the plantigrade state and have a plantigrade manus. The form of the pes of the genets is an adaptation for jumping. Prionodon is arboreal but have no metatarsal pads and is digitigrade. The ancestral condition is assumed to be plantigrady and arboreality and the presence of all the pads, which could be approach by some genets or Poiana, while the morphology of the foot of the Paradoxurinae, Nandinia and Cryptoprocta seems to be a secondary condition.

We investigated fluctuating asymmetry in 13 traits of the skulls and jaws of historical and contemporary populations of Scandinavian gray wolves (Canis lupus). We hypothesized that there is a higher level of fluctuating asymmetry in the inbred contemporary population than in the historical population. Our analyses did not detect any difference in the level of fluctuating asymmetry as predicted. We propose different explanation for this lack of change in fluctuating asymmetry. It is assumed that a large number of studies have failed to find a positive correlation between the level of genetic stress and developmental instability and have therefore never been published, which hampers a good understanding of fluctuating asymmetry as an indicator of developmental instability. The current study is thus important in this context. The gray wolf population in Scandinavia is characterized by an extreme bottleneck followed by two and a half decades of strong inbreeding, but no associated change in fluctuating asymmetry is detected.

“Miacid” carnivorans comprise one of the modern mammal groups appearing around the Palaeocene–Eocene Thermal Maximum (PETM) in the Northern Hemisphere. Here we describe a new very small “miacid” carnivoran from the earliest Eocene of Dormaal, Belgium, that shares a particular dental morphology with the species “Miacis” winkleri and “Miacis” rosei from the early Eocene of North America. The three species present very gracile and sharp teeth, and are hereby placed in the new genus Gracilocyon. Comparative dental analysis of Gracilocyon with other early “miacids” contributes to better resolve the polarity of dental characters and indicates that this genus is one of the most primitive members of the family. Diversity of early modern carnivorans is greater than previously considered and early “miacids” seem to have dispersed into North America from two different geographic origins.

Knowledge of a species’ distribution and habitat preferences is of paramount importance when assessing its conservation status. We used accurately recorded occurrence records and ecological niche modeling to predict the distribution of two poorly known small carnivore species that occur in Asia, the spotted linsang (Prionodon pardicolor) and banded linsang (Prionodon linsang), and analyzed their niche overlaps for habitat and elevation. We then assessed the loss of their suitable habitat and estimated the proportion of predicted presence under protected areas. We identified and assessed possible anthropogenic threats, and used our modeling predictions to recommend surveying priorities. Our study confirmed that these two linsangs are geographically separated, with no known overlap of their distributions. Our results indicated that the habitat and elevation niches of these two linsangs are similar: they both occur primarily in evergreen forest and can be found at all elevations up to around 3,000 m. Although these two linsangs might be allopatric due to intense interspecific competition between them, other explanations could explain their distribution patterns, such as biogeographical and ecological barriers. Our findings suggest that these two linsangs might be threatened by the loss, degradation, and fragmentation of tropical evergreen forests. Urgent field studies are thus needed to learn more about their habitat requirements and the impact of anthropogenic threats, including tropical forest disturbance and hunting.

nr 1

Thirty-four helminth species were obtained from the helminthological analysis of 399 foxes in the Iberian Peninsula. The species found were classified into three groups. Uncinada stenocephala, Eucoleus aerophilus and Pearsonema plica were classified as core species. The secondary species included Mesocestoides spp., Taenia polyacantha, Toxascaris leonina, Toxocara canis, Angiostrongylus vasorum, Crenosoma vulpis, Pterygodermatites affinis and Physaloptera sibirica. The remainder, including Alaria alata, Brachylaima sp., Metorchis bilis, Opistliorchis felineus, Taenia crassiceps, T. hydatigena, T. taeniaeformis, T. pisiformis, Echinococcus granulosus, Joyeuxiella pasqualei, J. echinorhynchoides, Diplopylidium noelleri, Aonchotheca putorii, Trichuris vulpis, Dirofilaria immitis, Toxocara cati, Ancylostoma caninum, Vigisospirura potekhinae, Molineus patens, M. legerae, Spirocerca lupi, Mastophorus maris and Macracanthorhynchus catulinus were considered as satellite species. A significantly high prevalence of trematodes was found in certain peninsular areas. The most prevalent and abundant cestodes were Mesocestoides spp. Nematodes were the most numerous set of species encompassing several of the most prevalent species. The findings of A. putorii and V. potekhinae constitute new host records for Vulpes vulpes, in the Iberian Peninsula (in the case of the capillariid) and in its entire geographical range (in the case of the spirurid). D. noelleri is also reported for the first time as parasitizing foxes in Europe. The majority of the species found are host generalists and have indirect life cycles. The richness of the helminth community seems to be strongly influenced by the broadness of the alimentary spectrum in different peninsular areas.

Morphometrical and biochemical-genetic comparisons were performed between wild IMustela vison energúmenos Bangs, 1896) and ranch mink (Dark Standard strain) to investigate intraspecific differences and to characterize effects of the domestication in this species. All animals were kept under similar conditions in larger open air enclosures prior to dissection to keep modificatory influences on the measures low and comparable. In the morphometrical part of this study weights of the total body, brain, eyes, thoracal viscera, heart, abdominal viscera, liver, spleen, kidneys, adrenals, and pancreas of 82 (39 males, 43 females) wild and 97 (50 males, 47 females) ranch mink were compared using the allometrical method with the net carcas weight as the reference parameter. Only three organs were significantly smaller in size in the ranch mink group: brain, heart, and spleen. Size decreases may result from reductions of central nervous and circulatory functions in the domesticated organism. They were compared with results in other species and evaluated as a genetically linked intraspecific adaptation to the special ecological demands of domestication. Twenty five proteins encoded by products of 44 genetic loci were compared electrophoretically between 7 wild and 7 ranch mink. Except for one esterase isozyme locus all genes examined were monomorphic. The protein heterozygosity was rather low in both groups. These results were discussed in connection with certain bottleneck situations, with investigations in other species, and with the short domestication time of ranch mink.

Gastrointestinal parasites were collected from 7 free-ranging Geoffroy's cats, Oncifelis geoffroyi from Lihué Calel National Park, Argentina. Also, fecal samples were analyzed from these animals and 3 other sympatric ones. The helminths were identified as Vigosospirura potekhina, Didelphonema longispiculata, Pterygodermatites cahirensis, Trichuris campanula, Ancylostoma tubaeforme, Toxocara cati, and Taenia sp. Fecal analysis revealed the presence of eggs of Capillaria sp. and an unidentified anoplocephalid tapeworm, and coccidian oocysts. The findings of V. potekhina, D. longispiculata, P. cahirensis, and T. campanula represent first records of these species in O. geoffroyi. Further, the former three had never been reported in South America.

The present study analyses the helminth communities found in one hundred and two specimens of Martes martes from the Iberian Peninsula and the Balearic Archipelago. The component community is constituted by seventeen helminth species, which frequency and mean abundance show a bimodal pattern. The set of core species is constituted by the trichurids Pearsonema plica, Eucoleus aerophilus and Aonchotheca putorii (72.2% of total helminth individuals found), while the remaining can be considered satellite species. Significant co-occurrences were found among E. aerophilus/A. putorii and E. aerophilus/P. plica. These results demonstrate the great importance of earthworms within the diet of pine marten and contribute to the knowledge of the pine marten’s food ethology, since this kind of prey normally goes undetected in diet studies. Several helminth species, as Sobolevingylus petrowi, Centrorhynchus aluconis, Uncinaria criniformis, Mastophorus muris and Spirura rytipleurites seurati seem to show geographical distributions limited to insular ecosystems. Moreover, helminth communities of M. martes among four Spanish territories, including mainland and insular areas, are characterized and compared.

The European mink (M. lutreola) and the American mink (M. vison) are riparian mustelids inhabiting Spain. During the last few decades, M. lutreola populations have declined almost everywhere, but, since being introduced in Europe, the American mink has become wide spread there. The present study presents the first comprehensive helminthological data of both mink species in Western Europe and analyses the possible cross-transmission of some pathogenic helminths between neighbouring Spanish populations of both mustelids. One hundred and forty specimens (28 M. lutreola and 112 M. vison) from several Spanish zones were analysed. A total of thirteen helminth species were found: Metorchis bilis, Parametorchis sp., Pseudamphistomum truncatum, Euryhelmis squamula and Apophallus donicus (Trematoda), Taenia martis and T. tenuicollis (Cestoda), Aonchotheca putorii, Strongyloides mustelorum, Molineus patens, Crenosoma melesi and Aelurostrongylus pridhami (Nematoda), and Centrorhynchus ninnii (Acanthocephala). The helminth fauna of M. lutreola was qualitatively and quantitatively richer than that of M. vison. This fact was particularly evident amongst digeneans with four species (M. bilis, Parametorchis sp., P. truncatum and A. donicus) exclusively present in M. lutreola. Twenty-five M. lutreola individuals were infected with parasitic worms (89.3%). In contrast, less than half (41.1%) of the American minks analysed were infected by helminths. The helminth fauna of both European and American minks in Spain are compared with those of both mustelids in Belarus, where another important population of M. lutreola is present. Also considered are some epidemiological and pathogenic aspects of the helminth fauna of both mink species that might act as regulatory factors over the Spanish population of M. lutreola.
