Tie Insects of flast-ftpeenland. By J. G. Nielsen. 1907. XXIX T h e following Catalogue of the Insect Fauna of East-Green- land, has chiefly been worked out from material collected by the Danish Expeditions. In recent years, three Expeditions have been sent from Den­ mark to the East Coast of Greenland. In the years 1883— 85, the “ Konebaads”-Expedition investigated the coast line from Kap Farvel to Angmagsalik under the direction of Capts G. Holm and Y. Garde, on this occasion P. Eberlin collected a few Insects. The main quantity of Insects from the East Coast, however, were collected by H. Deichmann, who took partin the Ryder Expedition to the district round Scoresby Sund in 1891— 92, from which place a few Insects were also brought back by H. Bay. On the Carlsberg Fund Expedition to East-Greenland which in the years 1898— 1900, under the direction of Lieutenant G. Am - dr u p , examined the coast from 66° N. to 72° N. H. Deic hm ann, together with the late Zoologist Soren Jensen and Dr. Knud Poulsen, also collected a quantity of Insects. Besides the knowledge that has been gained from these collections, notice is also taken here of all the previously published works on Insects from the East Coast. Of especial interest here is AuriviIlius’ work on the Lepidoptera and Coleoptera collected by the Swedish Expedition. The Greenland Insect Fauna resembles to a great extent the European. The greater quantity of the species belongs to 366 the common, North and Central European forms; a few of the species occur as alpine forms in the Central European moun­ tains and the Pyrenees, and are conspicuous by their absence in the intermediate low lying countries. Besides these, the Fauna includes pure arctic forms, that for the greater part have a wide distribution round the Polar Regions, and a pro­ portionally large quantity are described for the first time from Greenland and it is at present unknown whether they occur in other localities; they will most probably be found to have a much greater range, however, when the other Arctic countries are as carefully worked as Greenland. With the exception of the Strepsiptera, all the Orders of Insects are represented, but in a proportionally great difference of numbers. The D iptera are by far the largest order, with about 160 species, from this is a large spring to the Hymeno- p tera , M allophaga, Lepidoptera and Coleoptera with 52, 40, 39 and 26 species respectively; after these follow the Collembola and JSeuroptera with 13 and 6, while the remaining Orders are only represented by very few species. The East-Greenland Fauna is, to a great extent, the same as the West-Greenlands, the same species occurring in both places. The number of species appears to be lower in the first, than in the last named place; but this difference will, in all probability, be altered when the East coast has been more fully worked. While since Otto Fabricius’ time, collections have been made by the Danish inhabitants and Naturalists in West- Greenland, and the only special Entomological Expedition (Lundbeck 1889—90) alone worked the West, all that ‘has been done with the Insects from the East coast, has been done the few times that Expeditions have visited that part of the country. The order Coleoptera is represented in West-Greenland by 26 species, of which 8 (9) occur in the East, which has no species 367 that are specially confined to that portion of the country (with possibly the exception of one species of Homalota mentioned later). It is a strange occurrence that the family Carabidce, of which four species (three quite common) are found in the West, should be so wery poorly represented, as only one species, taken in a few specimens has occurred, and it is this family that goes highest North, and localities occur everywhere that are suitable to it. The number of imported Goleoptera in West- Greenland, has, in the course of time, reached no small number, of which two are found in the East (Cryptophagus validus and G. acutangulus), which have without doubt been brought up with the different Expeditions. The Hymenoptera follow after the D iptera with the greatest number of species (52). With the exceptions of two Humble- bees, that are common to both the East and West, and the three saw-flies, of which two are found in the West and one in the East, all the remainder belong to the Ichneumon-forms. All four families of the Ichneumons are represented in West- Greenland, but up to the present no representative of the Procto- trupidce has occurred in the East. Of the 52 species, 14 are common to both Coast lines, whilst 34 are exclusively belonging to the West- and 4 to East- Greenland, and in both localities there are a few species that are at present undetermined. The D iptera has by far the greatest number of representa­ tives in the Greenland fauna, in all about 160 species, of which a proportionally large number are only found in Greenland. Of these only 30 (31) species are common to both the East and West coasts, whilst 14 are only found in East-Greenland and the rest only in the West. With respect to the order Suctoria, at present only 5 species have been found in Greenland, of which 2 are common to both coast lines, 1 to the East only and 2 to the West. 368 The Lepidoptera number 39 species in Greenland, of which 14 are common to both coasts, 22 only in the West- and 3 in East-Greenland. The Rhopalocera appear to be more common in the East, for besides the two common species, Colias hecla and Argynnis chariclea var. arctica, two others occur, A rgynnis polaris, and Lyccena orbitulus var. aquilo, which appear to be rather common, whilst they have only been found a few times in West-Greenland on the northernmost part of the coast line. The Heterocera on the contrary, are much better represented in the West than the East, but as several of the species, for example of the two genera A grotis and P lusia, are exceedingly rare and in most cases are only represented by single old specimens, collected over a period of many years, it is pos­ sible that they have escaped the attention of the collectors on the East coast. Of the Neuroptera, 7 species are found in West-Greenland, of which only one species Apatania arctica also occurs in the East, while Pseudo-neuroptera and Orthoptera are only repre­ sented in the West. Of the Orthoptera, only the larva of a Blatta has been found on the West coast. The Hemiptera in West-Greenland reach the total of 12 species (4 Homoptera and 8 Heteroptera), of the first Group only one specimen has been found in East-Greenland, and of the second Group, two. Of the Mallophaga 40 species have been found, of which only 6 are common to both coasts, but as the birds that are hosts for these parasitic forms are, for the most part, widly distributed in both East- and West-Greenland, it is most pro­ bable that the number of species common to both parts will be greatly increased when more material is forthcoming. Of the Physopoda the common European species Physopus vulgatissimus, is in all probability found commonly both in the East and West. 369 Of the Collembola the Greenland fauna includes 13 species of which 6 occur only in the West, two in the East and 6 are common to both coasts. Catalogue of tlie Greenland Insects with, special reference to their geographical distribution. In the following list of the Insect fauna of Greenland the distribution given with each species is partly taken from the following list of Scientific Works, partly from a small collection of Insects from West-Greenland made by DrMeldorff in the neighbourhood of Julianehaab and partly from Vanhoffen’s x) list of Greenlands Fauna. The mention of the occurrence of Hemerobius orotypus in West-Greenland, is due to Mr. Esben Petersen, who received a specimen from Godthaab. Professor 0. G. Reuter of Helsingfors, who has received specimens of the Greenland Hemiptera from the Zoological Museum of Copenhagen, has kindly sent me the names of the species.

    SURVEYS FOR GYRFALCONS IN THE SCORESBYSUND REGION OF NORTHEAST GREENLAND IN 1999 TOM J. CADE1 AND ÓLAFUR K. NIELSEN2 1The Peregrine Fund, 5668 Flying Hawk Lane, Boise, Idaho 83709, USA. E-mail: [email protected] 2Icelandic Institute of Natural History, Urriðaholtsstræti 6–8, P.O. Box 125,212 Garðabær, Iceland ABSTRACT.—We conducted a helicopter survey over approximately 6,000 km2 of Jameson Land, East Greenland, on 9–10 June 1999 in search of nesting areas for Gyrfalcons (Falco rusticolus). An associate also carried out an overland skiing survey between Scoresbysund village and Self- eldene Peninsula on the Liverpool Coast in the later part of May, returning across the mountains of Liverpool Land to Constable Point. The authors also did a trip in dog-sledges between Scores- bysund village and Cape Höegh on the Liverpool Coast. We found 20 areas that showed signs of current, recent, and historical Gyrfalcon breeding activity, four on the Liverpool Coast and 16 in Jameson Land. Five had confirmed incubating females, seven others had apparent non-breeding pairs (n=2) or single adults present, and three could not be determined because of bad flying con- ditions. Kap Tobin, located near the entrance of Scoresbysund on its north side, appeared to be a suitable location for a trapping, banding, and marking station for fall migrating Gyrfalcons, and this assumption proved to be correct in 2004 and 2005. Comparing our findings with historical information from the 20th Century, while indicating that there could have been an overall decline of 50 percent in the nesting population of Gyrfalcons in NE Greenland since the mid-1900s, still the current population is substantial, and Scoresbysund remains an important location for studying the migratory movements of falcons along the East Greenland coast and associated marine habi- tats.

  • Geology of East Greenland
    The James Cresswell (UK) geologyof East Greenland ighty percent of Greenland is covered by ice and, in places, Ethis is up to 3.4km thick. So, Greenland might not immediately spring to mind as a place to go to observe rocks. However, it is a huge country and the ice-free area, at 410,000km2, is nearly twice the size of the UK. This is generally sparsely vegetated, leaving the rocks beautifully exposed and the geology incredibly easy to see. The area of East Greenland around Scoresby Sund, Kong Oscar and Kejser Franz Joseph Fjords is the largest ice-free area in Greenland. It also has incredible geodiversity, with basement rocks as old as three billion years, an almost complete sedimentary record of the last 1.6byrs and huge volumes of flood basalts from the splitting of the Atlantic. If you were an alien and wanted to try to piece together the geological story of Planet Earth - but could only visit one area - East Greenland would be the place to go. The geological history of Greenland is vastly long and spans 3.8byrs. Its oldest rocks are the 3.8byr-old Isua Complex, situated in West Greenland, near the capital Nuuk. These rocks are the Earth’s oldest, Fig 1.

  • Oxford University Liverpool Land Expedition Surrounding The
    Oxford University Liverpool Land expedition Surrounding the settlement of Ittoqqortoormiit, at the mouth of Scoresby Sund in North-East Greenland, is a geological terrain that records evidence of subduction to ultra-high pressures (depths of over 100km). These so called ‘ultra-high-pressure terrains’, typically found within mountain belts, provide a direct record of a poorly understood process: the subduction of continental crust. The Liverpool Land terrain, located in a steeply mountainous area within the Arctic Circle, is inaccessible even by the standards of ultra-high-pressure terrains and is therefore particularly understudied. The combination of excellent geology combined with a mountaineering challenge was part of the motivation for organising an Oxford University expedition during the summer of 2018. The aim of this expedition was to understand the metamorphic and structural history of this geological unit and collect samples for further petrological work, to archive with the geological survey of Denmark. As per any expedition plan, it was modified and changed on arrival into Greenland to account for weather, terrain and polar bears. The boat journey from Constable point across Hurry Inlet was relatively short and was reliant on my navigation skills using a 1:250,000 scale map whilst trying not to get sea sick or lose any maps to the wind. We were set down on the western side of the field area with a plan to back pack east onto the ‘plateau’ where we be in an ideal position to move around the area. As soon as we landed, many of the team members looked at the terrain sloping quite steeply to the east up to a high point of 700m, the incised rivers forming deep canyons filled with snow, the long, frozen lakes which feed these rivers and force you on a huge detour, and the miles of boulder fields with few or no campsites.

  • Towards an Integrated Jurassic Biostratigraphy for Eastern Greenland
    Volumina Jurassica, 2015, Xiii (1): 43–64 Doi: 10.5604/17313708 .1148657 Towards an integrated Jurassic biostratigraphy for eastern Greenland Simon R.A. KELLY 1, F. John GREGORY 2, William BRAHAM 3, Dominic P. STROGEN 4, Andrew G. WHITHAM 1 Key words: Jurassic, integrated biostratigraphy, ammonites, palynology, micropalaeontology, Greenland. Abstract. The thick and relatively complete Jurassic succession of eastern Greenland provides a unique biostratigraphic record for the North Atlantic region. The main biostratigraphic control for the succession has been provided by molluscs, especially ammonites and to a lesser extent by bivalves and belemnites. The late John Callomon and colleagues recognised 93 Boreal ammonite-bearing horizons in the Mid to Late Jurassic. This provides a reliable backbone to the biostratigraphy of these strata, prompting a palynological colleague to com- ment that they are the “Policemen of Jurassic Stratigraphy”. Other biostratigraphically significant microfossil and palynological groups, can be calibrated against this standard, but on their own cannot achieve the same precision. The Early Jurassic of eastern Greenland does not have such fine control as later parts of the period. No single biostratigraphic group can be used successfully throughout the interval, and there are only three significant ammonite faunas during this period. Reliance on various dif- ferent organisms is necessary to cope with the changing range of marine to non-marine environments. CASP field-work from 1990 to 2012 has resulted in the collection of much biostratigraphic material. In this article, published data are sum- marised together with previously unpublished data in the form of a unified table. The integrated chart shows detailed columns for the whole eastern Greenland Jurassic.
