Abstract:

This article examines several ways in which animals are brought into skiing in British Columbia, Canada. Discourse analysis, interviews with skiers, and field observation are used to analyze how skiing joins together skiers, mountain landscapes, and non-human animals. First, animals enter ski industry discourse primarily as symbols of nature, or as species that ski corporations manage through habitat stewardship. Second, environmentalists recruit animals—particularly bears and mountain caribou—into a discourse of wildlife and wilderness values that are threatened by ski industry expansion. From this standpoint, skiing landscapes transform wildlife landscapes to meet the needs of a global tourist economy. Finally, skiers' talk about their own encounters with animals illustrates how embodied animals also shape skiers' experience of mountainous nature.

Abstract:

Un programme de suivi à long terme permet d’évaluer l’efficacité des mesures d’atténuation installées sur l’autoroute Transcanadienne qui traverse le parc national de Banff, en Alberta, Canada. Depuis 1996, les passages fauniques conçus pour la grande faune ont été traversés plus de 218 000 fois. Les cerfs ont effectué 62 % des traversées contre 19 % pour les wapitis et < 8 % pour les grands carnivores. À disponibilité égale, les ours grizzlis, les orignaux, les cerfs et les wapitis ont semblé préférer les passages supérieurs (par-dessus la route) aux passages inférieurs, alors que les cougars et les coyotes ont utilisé les 2 types de structure également. Nous avons estimé que le temps d’adaptation aux passages fauniques variait entre 3 ans (cougar, ours noir) et 9 ans (ours grizzli, loup gris). En moyenne, pour les 8 espèces étudiées, la période d’adaptation initiale était de 4,4 ans, alors que la période d’adaptation complète était de 5,9 ans. Au cours des 15 dernières années, nous avons contribué à la recherche environnementale ainsi qu’à la gestion et la planification des transports, afin de concevoir des routes mieux adaptées aux populations animales.

Abstract:

The documentary film Grizzly Man (2005), directed by Werner Herzog, is of special interest among ecocritics and environmental advocates because it deals directly with the topic of wildlife depiction, conservationism and, above all the interspecies relationship between grizzlies and man. This article investigates five problematic elements of Grizzly Man as an ecological film: the wildlife documentary as a genre, the highly controversial figure of Timothy Treadwell who produced the original footage, the grizzlies in the background, the voice and hand of the director Herzog in this film, and the film’s ending. The analysis of these five areas may deepen the audiences’ understanding of both the film and the ecocritical approach to literature. Apart from highlighting certain contradictions in the film’s ecological message and its representation of wild animal, the article tries, in its conclusion, to examine the film’s potential to generate environmentally positive responses and create a better understanding of both wildlife and the key human figure in this film.

Abstract:

Radio-collared grizzly bears (Ursus arctos) were sighted daily for approximately 1-month periods during spring, summer, and fall to estimate predation rates. Predation rates on adult moose (Alces alces) were highest in spring, lowest in summer, and intermediate in fall. The highest kill rates were by male grizzlies killing cow moose during the calving period. We estimated that each adult male grizzly killed 3.3–3.9 adult moose annually, each female without cub(s) killed 0.6–0.8 adult moose and 0.9–1.0 adult caribou (Rangifer tarandus) annually, and each adult bear killed at least 5.4 moose calves annually. Grizzly predation rates on calves and grizzly density were independent of moose density and are probably more related to area-specific factors, e.g., availability of alternative foods. An important implication of our results is that managers should not allow moose densities to decline to low levels, because grizzlies can have a greater relative impact on low- than on high-density moose populations and because grizzly predation can be difficult to reduce. Grizzly bears were primarily predators, rather than scavengers, in this area of low prey availability (11 moose/grizzly bear); bears killed four times more animal biomass than they scavenged.

Abstract:

Activity pattern and food habits of Grizzled Giant Squirrel were investigated in Srivilliputhur Grizzled Giant Squirrel Wildlife Sanctuary from December 2011 to March 2012. Focal animal sampling method was used to record the activity pattern and food habits. Sampling was done in three different habitats viz., Private land, Reserve forest and Temple land. Feeding was the dominant activity accounting for 35.4% of the activity period. Bimodal feeding pattern was observed in Squirrels, the observations were made from early morning hours to till (0600-1800) late evening hours. The Squirrels feed upon 23 plant species; among them 11 were trees species, 10 climbers and 2 shrubs. Seven types of plant parts were used by Squirrels. Leaf consumption was high (38%) followed by fruit (24%). The high consumption of leaves was due to easy availability of leaves and limited availability of other plant parts. Squirrel’s invasion into Private Land and Temple Land was observed which can be attributed to abundance and easy availability of food plants, canopy continuity and less predatory pressure.

Abstract:

Domestic pigeons have high polymorphism in plumage morphs and colours. The genes that affect colour and coat patterns can be used to estimate genetic profiles that allow us to deduce the structures of populations, establish whether they are in a population equilibrium and learn the genetic similarity among them. This article tested these population components and the existing relationships among cities in northern South America, Western Europe and Singapore (Southeast Asia) through the inventory of phenotypic frequencies and the estimation of allele frequencies for the Pattern, Grizzle, Background colour, Spread, Crest, Recessive white and Feathered feet loci. The Hardy–Weinberg equilibrium was evaluated based on the Pattern and Grizzle loci. The results showed a higher genetic diversity in populations from northern South America with respect to the one from Western Europe, although the differentiation among cities was low ( GST = 0.0759). Several populations were not in the Hardy–Weinberg equilibrium for the evaluated loci, and a significant correlation between genetic and geographic distances was not found. The relatively small home range of the pigeons and the dispersion carried out by humans are discussed as possible explanations for the current genetic profiles.

Abstract:

Abstract Aegialomys galapagoensis (Waterhouse, 1839) is a sigmodontine rodent commonly called the Galapagos rice rat. It is a medium-sized rodent, characterized by dense, soft, yellow or copper, weakly grizzled pelage; the dorsum is grayish or brownish and the ventral pelage is pale. It is endemic to the open habitats of the Galapagos Archipelago, occurring on three islands, Santa Fé Island (Barrington Island), San Cristóbal Island (Chatham Island), and Santiago Island (James Island). Restricted populations are considered a major threat to A. galapagoensis conservation throughout most of its range, as well as competition with Rattus rattus. A. galapagoensis is listed as “Vulnerable” by the International Union for Conservation of Nature and Natural Resources, and is listed as “Critically Endangered” on the Ecuador National list.

Abstract:

The Grizzled Giant Squirrel (GGS) Ratufa macroura (Pennant, 1769) is a ‘Near Threatened’ and endemic giant squirrel distributed in southern India and Sri Lanka. In India, the species is distributed in more than 10 locations between Cauvery Wildlife Sanctuary in Karnataka in the north and Srivilliputhur Grizzled Squirrel Wildlife Sanctuary in Tamil Nadu in the south. A study was conducted in the riparian habitats of Chinnar Wildlife Sanctuary in Kerala to understand the habitat characteristics, including the drey site use of GGS. The vegetation of the GGS habitat was studied using the quadrat method, and the dreys were counted using the transects. A total of 95 species of trees were identified from the riverine vegetation, and the GGS used 36 species of trees for drey construction. Most of the dreys were found on Mangifera indica, Terminalia arjuna, Ficus microcarpa, Diospyros ebenum, and Pongamia pinnata. However, the GGS may prefer trees such as Mitragyna parviflora, Diospyros ebenum, Ficus microcarpa, Albizia procera, Acacia nilotica, and Acacia leucophloea for drey construction. The study also highlights the usage of large trees with extensive crown by the GGS for various activities such as feeding, resting, moving, and nesting, thus signifying the necessity for protecting the remaining riverine habitat at Chinnar Wildlife Sanctuary to ensure the long-term conservation of GGS. We recommend an urgent restoration by restocking with already existing, native tree species of the riverine habitat due to the extremely poor regeneration of trees in the riverine habitat that support the only population of the GGS in Kerala.

Abstract:

The mussel leech Batracobdella kasmiana (Oka, 1910) (Hirudinida: Glossiphoniidae) inhabits the mantle cavity of large freshwater mussels (Sawyer 1986; Lai & Chen 2010). This specific lifestyle is unusual in leeches although a few additional parasitic species from mussels have been reported (Grizzle & Brunner 2009). The known localities of B. kasmiana are situated in Japan (Honshu), continental China and Taiwan (Oka 1910, 1917; Gee 1919; Yang 1996; Yamauchi et al. 2008; Lai & Chen 2010). The majority of records were reported from continental China, in which this species is widely distributed across the eastern half of the country from Yunnan to Beijing (Yang 1996). It has never been mentioned as a member of the Russian fauna (Lukin 1976). A few naiad species in the family Unionidae are known hosts of B. kasmiana, including Sinanodonta spp., Cristaria plicata (Leach, 1815), and Nodularia douglasiae (Griffith and Pidgeon, 1833) (Oka 1917; Yang 1996; Yamauchi et al. 2008). The biology and ecological preferences of this leech species are poorly known (Yang 1996; Yamauchi et al. 2008; Lai & Chen 2010).

“Gallery Interactives: From Grizzlies to Polar Bears”. Canadian Museum of Nature, 16 Dec. 2009, http://nature.ca/discover/exm/frmgrzzlstplrbrs/index_e.html. Accessed 14 Feb. 2017.This short, educational game is designed to teach children about both polar and grizzly bears’ adaptations. It uses matching to allow users to choose between two different versions of an adaptation and drag them to either the polar or grizzly bear side. With the correct answer, a picture demonstrating that adaptation will appear and a box will pop up that explains in more detail the different adaptations. This game is educational in that it provides detailed information explained in simple language. It is also clear the user must drag the answer to a side, and what buttons to press once the box of information comes up. It holds the user’s hand almost too much but does not disrupt interaction. The interactivity of the game is limited because the only decisions users can make are by choosing the answers and if the wrong side is chosen, it moves back to the center. The graphic design is simple, using a muted blue color scheme, simple shapes, and a few static images but it could have used brighter colours or videos with audio to bring the animals to life. There also does not seem to be anything inventive because it is simply a matching game, with only two choices for each of the five levels, three of which focus on appearance. By having some incentive for the user to learn about each of the bears such as a mission or a problem to be solved, or by having more intuitive ways of choosing the answers, it would allow users to demonstrate their perceptiveness, build confidence and give them a feeling of investment in the material. For example, they could learn about the claws/pads by examining a trail of bear tracks. Overall this game is sufficient in its educational purpose but could do more to engage users.Recommended with reservations: 2 stars out of 4 Reviewer: Ellen NorlanderEllen Norlander is currently an MLIS student at the University of Alberta and hopes to enter the fields of either health sciences or academic librarianship.

Abstract:

AbstractWe assessed the distribution and relative abundance of giant squirrels and flying squirrels in the state of Karnataka, India. Two species of giant squirrels, the Indian giant squirrel and the grizzled giant squirrel, and two species of flying squirrel, the large brown flying squirrel and the small Travancore flying squirrel, were found to occur in Karnataka. Indian giant squirrels and large brown flying squirrels were more widely distributed than the other two species. The distributional range included the forests of the Western and Eastern Ghats. However, their distribution was confined only to forests with tall trees. Indian giant squirrels and large brown flying squirrels occur in both deciduous and evergreen forests. Small Travancore flying squirrels occupied high-rainfall evergreen forests on western slopes in the Western Ghats, and the grizzled giant squirrels occupy riverine forests. This report of the small Travancore flying squirrel is the first of this species from Karnataka, and this population is the most northern population of its distributional range. Hunting was found to be a major threat, and influenced the abundance of all species except the grizzled giant squirrel. Hunting was primarily for domestic consumption.

Abstract:

The concept of «partblood» most are based on assumptions about longing action of genes that control is taken part in polygenic traits productivity and their system of uniform distribution of landed offspring. The literature describes few actual studies of genetic processes that occur in the offspring of crosses purebred animals. In this regard, the task of our study included a comparative analysis of the genetic structure of the source rocks (symentaly, grizzled red–Holstein) and their offspring landed the «share of blood» 1/2 (F1) and 3/4 (F2). Analysis of the genetic structure of all four groups of animals by polymorphic genetic and biochemical systems showed that transferrin locus for the particular animals are different from parental forms. So a group of animals with 1/2 blood (F1) display of high frequency of allelic variant Tf D2 (0,646). According to AM–1 locus in the studied groups manifestation of the highest frequency in the group of animals 1/2 halfblood (F–1) – 0.712 and this group is just as close to a group of purebred symentaliv (0.806). For purynnukleotydfosforylazy locus was found a high frequency of phenotypes at high activity in a group of purebred symentaliv (NP–H – 0,25). Cluster analysis showed that for genetic and biochemical systems group symentaliv (bedrock) form one cluster, and the Local animals (F–1 i F–2), and a group of red Holstein (parent rock) differs from them with a group black and other forms black Holstein, an independent cluster.

Abstract. Husodo T, Shanida SS, Febrianto P, Pujianto MP, Megantara EN. 2019. Mammalian diversity in West Java, Indonesia. Biodiversitas 20: 1846-1858. Protected forests in West Java are wider than conservation forests, whereas mammalian diversity in protected forests is as high as mammalian diversity in conservation forests. Mammals in protected forests are not protected by regional protection regulations, while anthropogenic factors in Java are quite high. This is possible that mammals who have high conservation status will experience local extinction. This study aims to determine (i) the composition of mammalian species and (ii) the species that are always found in studies of mammalian diversity in West Java. The study was conducted through a qualitative approach by combining several methods such as interview, camera trapping, sign survey, observation and transect, and collapsible traps. Mammalia in West Java found 54 species, 21 families, and nine orders with details of three species of Artiodactyla, 12 species of Carnivores, seven species of Chiroptera, one species of Dermoptera, one species of Euphotyphla, one species of Pholidota, five species of Primates, 21 species of Rodentia, and three species of Scandentia. The species that are always found in all study locations are nine species, including wild boar, Javan leopard, leopard cat, Javan mongoose, oriental small-clawed otter, Asian palm civet, grizzled leaf monkey, Javan langur, and Javan tree shrew. The results presented here may facilitate improvements in the mammalian diversity database, especially in the non-conservation area.
