AbstractCentral North Greenland, an uninhabited and rarely visited region bordering the Arctic Ocean, supports arctic hare, collared lemming, wolf, arctic fox, polar bear, stoat, ringed seal and musk ox. Their distribution and abundance were noted during Geological Survey of Greenland expeditions in 1984–85, which visited virtually all land areas in the region, including nunataks and islands. Bones of reindeer, bearded seal and narwhal were also found. Ringed seal and reindeer are known to have been present in the region by the early Holocene.

Kalluk, Celina.  Sweetest Kulu. Illus. Alexandria Neonakis.  Iqaluit, NU:  Inhabit Media Inc., 2014.  Print.“Kulu” is an Inuktitut term of endearment for babies and small children.  In this work, traditional throat singer and author, Celina Kalluk, shows all of the gifts that nature brings to a newborn baby.  The images show the baby cradled and adored by many creatures.  Each creature brings a character trait as a gift for the baby.  “Caribou chose patience for you, cutest Kulu.  He gave you the ability to look to the stars, so that you will always know where you are and may gently lead the way”.  With each gift, Kalluk uses a different adjective to describe the baby – happy Kulu, admired Kulu, beloved Kulu. Illustrator, Alexandria Neonakis has created an image for each animal in rich and deep colours.  The images spread over two facing pages with text over-printed. Each image is gentle and tender.  The baby is shown nestled between the front hooves of a musk-ox, curled up against a polar bear or snuggled up in the paws of an Arctic hare.  The baby is reflected in the water when the Arctic char brings a gift of tenderness.This book is a beautiful representation of a mother’s love for her baby reflected in the traditional Inuit connection to the land and nature.  It is a calming and peaceful book, which will become a bedtime read-aloud favourite. Highly recommended for elementary school libraries, public libraries and babies’ rooms everywhere.Highly Recommended:   4 stars out of 4Reviewer:  Sandy CampbellSandy is a Health Sciences Librarian at the University of Alberta, who has written hundreds of book reviews across many disciplines.  Sandy thinks that sharing books with children is one of the greatest gifts anyone can give.

Arctic Hare

Unlike other lagomorphs or any other mammals living in a cold environment, the basal metabolic rate of the arctic hare, Lepus arcticus monstrabilis (0.36 cm3 O2/g per hour) was only 62–83% of the values predicted from its body weight. The minimum thermal conductance (0.010 cm3 O2/g per hour per degree centigrade) was also reduced to only 51–59% of its weight-specific value (0.019–0.017 cm3 O2/g per hour per degree centigrade). The normal body temperature (38.9C), however, was comparable to that of other lagomorphs. The daily energy consumption between ambient temperatures of −24 and 12.5C was between 262 and 133 kcal, which is 6–43% above the minimum resting values at corresponding ambient temperatures.It is concluded that the reduction of surface area to volume ratio and the effectiveness of its insulation are sufficient compensations so that the arctic hare can maintain a normal body temperature with a depressed basal metabolic rate. Such a reduction of metabolism is energetically adaptive for a species living exclusively in a cold and relatively barren habitat.

Composite Samples

Morphometric variation in 21 characters of 470 skulls of Lepus arcticus from Canada and Greenland was analysed statistically. Geographic trends in variation were assessed separately in Canada and Greenland using composite samples derived from groupings of geographically contiguous localities. For most characters, univariate analyses revealed clines of decreasing size from the polar regions southwards, though jugal maxillary ridge width exhibited a reverse cline and maxilla orbital process width varied irregularly among samples. Discriminant analysis synthesized these trends such that the phenetic positions of the samples in discriminant space were approximately congruent with their geographic positions. The smoothness of the cline is interrupted between the Queen Elizabeth Islands and the islands of the lower Arctic Archipelago and is not paralleled by similar sharp environmental transitions. Gene flow across the water gap therefore seems to be very restricted. Discontinuities among the Greenland samples can be attributed partly to sampling or distributional hiatuses, but infraspecific differentiation appears to be occurring on either side of the Melville Bay glacial barrier. Statistically significant multiple regressions of factor scores of climatic variables on factor scores of skull morphology suggest thermoregulatory adaptation as a result of selection for increased skull size in colder climates, as is subsumed by Bergmann's rule.

Hare Population

We determined demographic attributes of an arctic hare (Lepus arcticus) population in the Southern Long Range Mountains of Newfoundland. Twenty-four adult hares were livetrapped, radio collared, and monitored from July 1981 through July 1984. From livetrapping and an aerial census we estimated mean density at about 1 adult/km2. A single litter was born annually and natality averaged 3.0 young/female. Mean dates of conception and parturition were 19 April and 8 June, respectively. Annual survival rate of radio-collared adults was 0.78; calculated 1st-year survival rate of juveniles was 0.15. Natural mortality was mainly from red foxes (Vulpes vulpes). One-year-old individuals comprised 18% of 68 adult hares shot in May. Sex ratios were biased towards males in both trapped and shot samples. Summer home range size of three adult females (52–69 ha) averaged half that of three adult males (116–155 ha). Movements increased in March and April with onset of breeding activity. It is unlikely that winter food shortage affected survival, as hares collected in May had both kidney fat and relatively high levels of bone marrow fat. Annual differences in these condition indices were, however, reflected in several reproductive parameters. We hypothesize that the single litter and small litter size which combine to give Newfoundland arctic hares the lowest reproductive potential of any known hare population are a consequence of (i) the late spring that delays onset of breeding until April, and (ii) the shorter day length in April and hence lower gonadotrophin levels at this southernmost limit of distribution. We believe that predation on juveniles is the paramount limitation on growth of this arctic hare population, and primarily responsible for the stabilization at low densities.

Arctic Hare

The grey wolf (Canis lupus Linnaeus, 1758) is one of the most widespread large carnivores on Earth, and occurs throughout the Arctic. Although wolf diet is well studied, we have scant information from high Arctic areas. Global warming is expected to increase the importance of predation for ecosystem regulation in Arctic environments. To improve our ability to manage Arctic ecosystems under environmental change, we therefore need knowledge about Arctic predator diets. Prey remains in 54 wolf scats collected at three sites in the high Arctic region surrounding the Hall Basin (Judge Daly Promontory, Ellesmere Island, Canada, and Washington Land and Hall Land, both in northwestern Greenland) pointed to a dietary importance of arctic hare (Lepus arcticus Ross, 1819; 55% frequency of occurrence) and muskoxen (Ovibos moschatus (Zimmermann, 1780); 39% frequency of occurrence), although we observed diet variation among the sites. A literature compilation suggested that arctic wolves (Canis lupus arctos Pocock, 1935) preferentially feed on caribou (Rangifer tarandus (Linnaeus, 1758)) and muskoxen, but can sustain themselves on arctic hares and Greenland collared lemmings (Dicrostonyx groenlandicus (Traill, 1823)) in areas with limited or no ungulate populations. We suggest that climate change may alter the dynamics among wolves, arctic hare, muskoxen, and caribou, and we encourage further studies evaluating how climate change influences predator–prey interactions in high Arctic environments.

Arctic Hare

The Arctic hare is a traditional favorite hunting object in Russia. One of the main tasks of ecology is the study of populations. The most important quantitative parameter for a biological community is the change in the number of its specimen. On the basis of official data on animal counts over the past 25 years, we have established some characteristics that provide information on the state of the Arctic hare resources in the Ryazan and Tula regions. The aim of this work was to carry out a population analysis of the Arctic hare resources in the south of the Moscow region in the Ryazan and Tula regions over the past 25 years. The population analysis included studying static (the number and density of the hare population, the volume of prey, as well as the long-term average value of the number) and dynamic (the dynamics of the number and volume of prey, the absolute and relative rate of change in the population size) indicators. Primary data on the population of hares were collected using the winter route accounting method. The population density of hares was determined on the total territory of the hunting grounds in the corresponding territory. Basing on the data obtained, it was revealed that over the past quarter of a century, the number of Arctic hares in the Ryazan region has a tendency to decrease. The population density of Arctic hares in 1995 and 2019 in the Tula region remained practically at the same level. The indicator of the Arctic hare kill in both Ryazan and Tula regions tends to decrease.

Rumbolt, Paula Ikuutaq. The Origin of Day and Night. Iqaluit, NV, Inhabit Media, 2018. This book is another in Inhabit Media’s collection of works that document traditional Inuit stories. Origin stories, which explain why things are the way they are, are common in Inuit storytelling. This one tells us how night and day came to be. In the time when animals and words had special powers, the Tiri, the Arctic fox, and Ukaliq, the Arctic hare, both want to hunt. The fox can see in the dark, so he uses his words to keep the world dark. The hare needs light to see, so she uses her words to bring light. They change night to day and day to night, frustrating each other, until they agree to give each other “enough time to find a meal or two” before changing the light. As a result, we have night and day.  Lenny Lishchenko’s illustrations are simple, but support the story effectively. They are mainly in blacks, blues and whites, appropriate to night and day. The animals are outlined in black on white or white on black, with a few details added. There are a few reds and yellows, for the animals’ eyes, the sun, meat and berries.  This rendition of the story will capture the interest of the young children, who are the intended audience. Highly recommended for public and elementary school libraries, as well as collections that specialize in polar children’s literature. Highly Recommended:  4 out of 4 starsReviewer:  Sandy Campbell Sandy is a Health Sciences Librarian at the University of Alberta, who has written hundreds of book reviews across many disciplines. Sandy thinks that sharing books with children is one of the greatest gifts anyone can give.
