Changes in vegetation structure can alter the physical habitat structure, thermal environment, and food available to arthropods, which play an important role in the structure and functioning of Arctic ecosystems. Not only do they provide key ecosystem services such as pollination and nutrient cycling, they are an essential food source for migratory birds. In this study I examined the relationships between the abundance, diversity, and community composition of arthropods and the height and cover of several shrub species across a tundra-shrub gradient in northwestern Alaska. To characterize nestling diet of common passerines that occupy this gradient, I used next-generation sequencing of fecal matter. Willow cover was strongly and consistently associated with abundance and biomass of arthropods and significant shifts in arthropod community composition and diversity. -
Micmac Migration to Western Newfoundland
MICMAC MIGRATION TO WESTERN NEWFOUNDLAND DENNIS A. BARTELS Department of Anthropology Sir Wilfred Grenfell College Memorial University of Newfoundland Corner Brook, Newfoundland Canada, and OLAF UWE JANZEN Department of History Sir Wilfred Grenfell College Memorial University of Newfoundland Corner Brook, Newfoundland Canada, ABSTRACT / RESUME The Micmac of Cape Breton are known to have had a long history of seasonal contact with Newfoundland. It is generally accepted that they resided there permanently by the early 19th century. The authors review the available evidence and conclude that the permanent occupation of Newfoundland by the Micmac began in the 1760s. On sait que les Micmac de cap-Breton ont eu une longue histoire du contact saisonnier avec la Terre-Neuve. Il est généralement admis qu'ils y habitèrent en permanence au début du XIXe siècle. Les auteurs examinent l'évidence disponible et concluent que l'occupation permanente de la Terre-Neuve par les Micmac a commencé dans les années 1760. 72 Dennis A. Bartel/Olaf Uwe Janzen INTRODUCTION It is generally conceded that the Micmac of Cape Breton Island were a maritime-adapted people with sufficient seafaring skills to extend their territorial range as far into the Gulf of St. Lawrence as the Magdalen Islands and as far east as St. Pierre and Miquelon.1 By the eighteenth century, the Micmac were able to maintain a persistent presence in southern and southwestern Newfoundland. Some scholars have concluded from this that southwestern Newfoundland could have been a regular part of the territorial range of the Cape Breton Micmac since prehistoric times.2 In the absence of archaeological evidence to support such a conclusion, others, such as Marshall (1988) and Upton (1979:64) are unwilling to concede more than a seasonal exploitation of Newfoundland. -

This was the second series of open consultations with inshore fish harvesters, the first series took place in the fall and winter of 2017-18. The purpose of these consultations was to provide a forum for individual harvesters and their representatives to raise concerns and ask questions During the meetings on a wide range of fishery management topics. The meetings featured fish harvesters asked flexible agendas and allowed significant harvester participation. questions and offered During the meetings fish harvesters asked questions and offered their their perspectives about perspectives about various aspects of fisheries management and science. Fisheries and Oceans Canada (DFO) also took the opportunity to address various aspects of the questions and concerns raised during the previous consultations in fisheries management 2017-18. and science. Topics discussed and questions raised in the meetings centred upon five general themes: • The timing of fishery openings and closures; • The way fishery overlap privileges near the boundaries of major fishing zones are managed; • Sharing arrangements for fish stocks, particularly those in which harvesters from neighbouring regions are allocated greater shares than harvesters from Newfoundland and Labrador; • Permitting more buddy-up arrangements; and • Vessel length restrictions and vessel replacement rules. -
Spiders (Araneae) of Churchill, Manitoba: DNA Barcodes And
Blagoev et al. BMC Ecology 2013, 13:44 http://www.biomedcentral.com/1472-6785/13/44 RESEARCH ARTICLE Open Access Spiders (Araneae) of Churchill, Manitoba: DNA barcodes and morphology reveal high species diversity and new Canadian records Gergin A Blagoev1*, Nadya I Nikolova1, Crystal N Sobel1, Paul DN Hebert1,2 and Sarah J Adamowicz1,2 Abstract Background: Arctic ecosystems, especially those near transition zones, are expected to be strongly impacted by climate change. Because it is positioned on the ecotone between tundra and boreal forest, the Churchill area is a strategic locality for the analysis of shifts in faunal composition. This fact has motivated the effort to develop a comprehensive biodiversity inventory for the Churchill region by coupling DNA barcoding with morphological studies. The present study represents one element of this effort; it focuses on analysis of the spider fauna at Churchill. Results: 198 species were detected among 2704 spiders analyzed, tripling the count for the Churchill region. Estimates of overall diversity suggest that another 10–20 species await detection. Most species displayed little intraspecific sequence variation (maximum <1%) in the barcode region of the cytochrome c oxidase subunit I (COI) gene, but four species showed considerably higher values (maximum = 4.1-6.2%), suggesting cryptic species. All recognized species possessed a distinct haplotype array at COI with nearest-neighbour interspecific distances averaging 8.57%. Three species new to Canada were detected: Robertus lyrifer (Theridiidae), Baryphyma trifrons (Linyphiidae), and Satilatlas monticola (Linyphiidae). The first two species may represent human-mediated introductions linked to the port in Churchill, but the other species represents a range extension from the USA. -

THE BIOLOGY AND POPULATION ECOLOGY OF flACROSTELES SEXNOTATUS (FALLEN) (CICADELLIDAE, HEnIPTERA) by Miriam Becker, M.Sc. (Brazil) December, 1974 A thesis submitted for the degree of Doctor of Philosophy of the University of London and for the Diploma of Imperial College Imperial College of Science and Technology, Silwood Park, Ascot, Berkshire. 2 ABSTRACT Studies in the laboratory and under field conditions were made on the biology and population ecology of Macrosteles sexnotatus (Fall6n) (Cicadellidae, Hemiptera). Laboratory studies on the biology were carried out under a set of constant temperature conditions. The rela- tionship between temperature and rates of egg and nymphal development are presented and discussed. Effects of tempera- ture on fecundity and longevity were also studied, and choice of oviposition sites under laboratory and field conditions were investigated. Studies were carried out to induce hatching of diapausing eggs and also to induce diapause in the eggs. The internal reproductive organs of males and females are described and illustrated. Illustrated descrip- tions are also given of the five nymphal stages and sexes are distinguished from third instar onwards. Descriptions and illustrations are given of a short winged form which occurred in the laboratory cultures. Population studies_of M. sexnotatus in an catfield • were carried out from 1972 to 1974. Adults and nymphs were sampled regularly with a D-vac suction sampler and occa- sionally with a sweep net. Weekly population estimates were made from June to late September for 1973 and 1974 and for August and September of 1972. Population budgets are presented and causes of mortality are discussed. Losses caused by parasitism in the nymphal and adult stages are 3 shown to be smaller than those within the egg stage. -
Distribution of Spiders in Coastal Grey Dunes

The knowledge of dispersal evolution, motivation, its effect on metapopulation dynamics and species distribution at multiple scales is poorly understood and many questions remain unsolved or require empirical verification. In this thesis we contribute to the knowledge of dispersal, by studying both ecological and evolutionary aspects of spider dispersal in fragmented grey dunes. Studies were performed at the individual, population and assemblage level and indicate that behavioural traits narrowly linked to dispersal, con- siderably show [adaptive] variation in function of habitat quality and geometry. Dispersal also determines spider distribution patterns and metapopulation dynamics. Consequently, our results stress the need to integrate knowledge on behavioural ecology within the study of ecological landscapes. / Promotor: Prof. Dr. Eckhart Kuijken [Ghent University & Institute of Nature Dries Bonte Conservation] Co-promotor: Prf.

Do Incremental Increases of the Herbicide Glyphosate Have Indirect Consequences for Spider Communities?
2002. The Journal of Arachnology 30:288±297 DO INCREMENTAL INCREASES OF THE HERBICIDE GLYPHOSATE HAVE INDIRECT CONSEQUENCES FOR SPIDER COMMUNITIES? James R. Bell: School of Life Sciences, University of Surrey Roehampton, Whitelands College, West Hill, London SW15 3SN, UK Alison J. Haughton1: Crop and Environment Research Centre, Harper Adams University College, Newport, Shropshire, TF10 8NB, UK Nigel D. Boatman2: Allerton Research and Educational Trust, Loddington House, Loddington, Leicestershire, LE7 9XE, UK Andrew Wilcox: Crop and Environment Research Centre, Harper Adams University College, Newport, Shropshire, TF10 8NB, UK ABSTRACT. We examined the indirect effect of the herbicide glyphosate on ®eld margin spider com- munities. Glyphosate was applied to two replicated (n 5 8 per treatment) randomized ®eld experiments over two years in 1997±1998. Spiders were sampled using a modi®ed garden vac monthly from May± October in the following treatments: 1997 comprised 90g, 180g, & 360g active ingredient (a.i.) glyphosate ha21 treatments and an unsprayed control; 1998 comprised 360g, 720g and 1440g a.i. glyphosate ha21 treatments and an unsprayed control. We examined the indirect effect of glyphosate on the spider com- munity using DECORANA (DCA), an indirect form of gradient analysis. We subjected DCA-derived Euclidean distances (one a measure of beta diversity and the other a measure of variability), to the scrutiny of a repeated measures ANOVA design. We found that species turnover and cluster variation did not differ signi®cantly between treatments. We attribute the lack of any effect to a large number of common agricultural species which are never eliminated from a habitat, but are instead signi®cantly reduced. -
