<p>Nematodes of the genus <em>Elaphostrongylus</em>&nbsp;collected from moose (<em>Alces alces</em> L.), reindeer (<em>Rangifer tarandus tarandus</em> L.), and red deer (<em>Cervus elaphus</em> L.), respectively, were studied by means of scanning electron microscopy. Morphological differences in the ribs of the genital bursa were demonstrated. The <em>Elaphostrongylus</em> species from reindeer and red deer differed from each other in four ribs of the genital bursa. These results agree with the morphological characters of <em>E. cervi</em> and <em>E. rangiferi</em> described by Cameron (1931) and Mitskevitch (1960). The genital bursa of <em>Elaphostrongylus</em> sp. from moose, in accordance with the description of <em>E. alces</em> by Steen <em>et al</em>. (1989) showed characteristics differing from those found in <em>Elaphostrongylus</em> spp. from reindeer and red deer respectively. These results support the hypothesis that there are three separate species of <em>Elaphostrongylus</em> present in Scandinavian Cervidae.

To test the hypothesis that palearctic cervids are infected with several species of Elaphostrongylus, reindeer (Rangifer tarandus tarandus) calves were inoculated with third-stage larvae grown in Arianta arbustorum from first-stage larvae extracted from reindeer, red deer (Cervus elaphus atlanticus), and moose (Alces alces) feces. None of the five reindeer calves inoculated with larvae from red deer and none of the three reindeer calves inoculated with larvae from moose became infected. Twelve of the 14 reindeer calves inoculated with larvae from reindeer became infected. Infection was demonstrated by finding first-stage larvae in the feces and (or) by finding worms at necropsy. These results suggest that several species of Elaphostrongylus parasitize palearctic cervids. In view of our results and the need for further taxonomic work on the group, it is argued that the names Elaphostrongylus cervi and Elaphostrongylus rangiferi should be reserved for worms from red deer and reindeer, respectively. Worms from moose may belong to an undescribed species.

Gammaherpesvirus infections have been described in cervids worldwide, mainly the genera Macavirus or Rhadinovirus. However, little is known about the gammaherpesviruses species infecting cervids in Norway and Fennoscandia. Blood samples from semi-domesticated (n = 39) and wild (n = 35) Eurasian tundra reindeer (Rangifer tarandus tarandus), moose (Alces alces, n = 51), and red deer (Cervus elaphus, n = 41) were tested using a panherpesvirus DNA polymerase (DPOL) PCR. DPOL-PCR-positive samples were subsequently tested for the presence of glycoprotein B (gB) gene. The viral DPOL gene was amplified in 28.2% (11/39) of the semi-domesticated reindeer and in 48.6% (17/35) of the wild reindeer. All moose and red deer tested negative. Additionally, gB gene was amplified in 4 of 11 semi-domesticated and 15 of 17 wild Eurasian reindeer DPOL-PCR-positive samples. All the obtained DPOL and gB sequences were highly similar among them, and corresponded to a novel gammaherpesvirus species, tentatively named Rangiferine gammaherpesvirus 1, that seemed to belong to a genus different from Macavirus and Rhadinovirus. This is the first report of a likely host-specific gammaherpesvirus in semi-domesticated reindeer, an economic and cultural important animal, and in wild tundra reindeer, the lastpopulation in Europe. Future studies are required to clarify the potential impact of this gammaherpesvirus on reindeer health.

AbstractThe rumen microbiota comprises a community of microorganisms which specialise in the degradation of complex carbohydrates from plant-based feed. These microbes play a highly important role in ruminant nutrition and could also act as sources of industrially useful enzymes. In this study, we performed a metagenomic analysis of samples taken from the ruminal contents of cow (Bos Taurus), sheep (Ovis aries), reindeer (Rangifer tarandus) and red deer (Cervus elaphus). We constructed 391 metagenome-assembled genomes originating from 16 microbial phyla. We compared our genomes to other publically available microbial genomes and found that they contained 279 novel species. We also found significant differences between the microbiota of different ruminant species in terms of the abundance of microbial taxonomies, carbohydrate-active enzyme genes and KEGG orthologs. We present a dataset of rumen-derived genomes which in combination with other publicly-available rumen genomes can be used as a reference dataset in future metagenomic studies.

SummaryTwo shoulder blades with healed lesions found at the Mesolithic settlement Star Carr are described, one of an elk (Alces alces (L.)) and the other front red deer (Cervus elaphus L.). Their presence at the site throws light on the question of seasonal occupation, indicating that the site has been populated at least during winter time. In addition, some comments are made on the supposed lesions on the elk from High Furlong, Lancashire.

AbstractThe rumen microbiota comprises a community of microorganisms which specialise in the degradation of complex carbohydrates from plant-based feed. These microbes play a highly important role in ruminant nutrition and could also act as sources of industrially useful enzymes. In this study, we performed a metagenomic analysis of samples taken from the ruminal contents of cattle (Bos Taurus), sheep (Ovis aries), reindeer (Rangifer tarandus) and red deer (Cervus elaphus). We constructed 391 metagenome-assembled genomes originating from 16 microbial phyla. We compared our genomes to other publically available microbial genomes and found that they contained 279 novel species. We also found significant differences between the microbiota of different ruminant species in terms of the abundance of microbial taxonomies, carbohydrate-active enzyme genes and KEGG orthologs. However, we found that the vast majority of carbohydrate-active enzymes were present in all of our sample types, which may indicate that there is a core set of these enzymes which are present across ruminants and are independent of diet and environmental conditions. We present a dataset of rumen-derived genomes which in combination with other publicly-available rumen genomes can be used as a reference dataset in future metagenomic studies.Data SummaryThe paired-read fastq files supporting the conclusions of this article are available in the European Nucleotide Archive repository (https://www.ebi.ac.uk/ena/browser/view/PRJEB34458).

Seven third instar larvae of the reindeer warble fly (Hypoderma (=Oedemagena) tarandi) were found in a 2-3 year old male red deer {Cervus elaphus) shot on 14 November 1985 at Todalen, western Norway. This it, the first report of H. tarandi from red deer. In reindeer third instar larvae are found from February to June, and the unusual date of this record indicates a delayed development of the larvae due to abnormal host reactions. Warble fly larvae, probably H. tarandi, are also reported from moose {Alces alces) in northern Norway.

Coptoformica Müller, 1923 is a subgenus of Formica Linnaeus, 1758 that consists of c. a dozen species of ants that typically inhabit open grassy habitats and build small nest mounds. The most recent addition to the group is Formica fennica Seifert, 2000. The description was based on morphological characters, but the species status has not been confirmed by molecular methods. In this study, we use thirteen DNA microsatellite markers and a partial mitochondrial COI gene sequence to assess the species status of F. fennica, by comparing the genetic variation among samples identified as F. fennica and six other boreal Formica (Coptoformica) species. Most of the species studied form separate, discontinuous clusters in phylogenetic and spatial analyses with only little intraspecific genetic variation. However, both nuclear and mitochondrial markers fail to separate the species pair F. exsecta Nylander, 1846 and F. fennica despite established morphological differences. The genetic variation within the F. exsecta/fennica group is extensive, but reflects spatial rather than morphological differences. Finnish F. fennica populations studied so far should not be considered a separate species, but merely a morph of F. exsecta.
