  1. 1. Aspects of locomotor evolution in the Carnivora (Mammalia)

    Author : Ki Andersson; Lars E. Holmer; Lars Werdelin; Margaret E. Lewis; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Morphology; Mammalia; Carnivora; Locomotion; Cranial; Elbow joint; Morphology; Morphometrics; Landmarks; Multivariate statistics; Allometry; Ecomorphology; Dental; Body size; Morfologi; Morphology; cell biology; pathology; Morfologi; cellbiologi; patologi;

    Abstract : In this thesis, the shape of the distal humerus trochlea is analysed using landmark-based morphometrics and multivariate methods, with the aim of exploring locomotor evolution in carnivorans. Elbow joint morphology is used together with body size and craniodental morphology to characterize past and present carnivorans. READ MORE

  2. 2. Modeling and Control for Emission Management in Hybrid Electric Commercial Vehicles

    Author : Olov Holmer; Lars Eriksson; Christopher Onder; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Electrification of powertrains is a major trend in the vehicle industry. The reason behind this is mainly that electrification of a powertrain generally results in better fuel economy, by eliminating inefficient, low load, operation of the engine. READ MORE

  3. 3. The Cambrian lophotrochozoans of the Transantarctic Mountains, Antarctica

    Author : Lewis Bassett-Butt; Lars Holmer; Glenn Brock; Christian Skovsted; Jan Ove Ebbestad; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Brachiopoda; Dailyatia; Cambrian; Drumian; Middle Cambrian; Early Cambrian; Antarctica; tommotiid; camenellan; palaeobiology; small shelly fossils; Earth Science with specialization in Historical Geology and Palaeontology; Geovetenskap med inriktning mot historisk geologi och paleontologi;

    Abstract : The origin of many lophotrochozoan groups can be traced to “small shelly fossil” (SSF) faunas of the Early Cambrian. Antarctica is a key region of study, due to the continent’s known close geographical proximity to well-studied Australian and Indian basins in in the Cambrian. READ MORE

  4. 4. Decoding the fossil record of early lophophorates : Systematics and phylogeny of problematic Cambrian Lophotrochozoa

    Author : Aodhán D. Butler; Michael Streng; Lars E. Holmer; Russell Garwood; Maggie Cusack; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Brachiopoda; Chengjiang; Lagerstätte; Cambrian Explosion; palaeobiology; stem-group; entoproct; phoronid; tommotiid; exceptional preservation; Earth Science with specialization in Historical Geology and Palaeontology; Geovetenskap med inriktning mot historisk geologi och paleontologi;

    Abstract : The evolutionary origins of animal phyla are intimately linked with the Cambrian explosion, a period of radical ecological and evolutionary innovation that begins approximately 540 Mya and continues for some 20 million years, during which most major animal groups appear. Lophotrochozoa, a major group of protostome animals that includes molluscs, annelids and brachiopods, represent a significant component of the oldest known fossil records of biomineralised animals, as disclosed by the enigmatic ‘small shelly fossil’ faunas of the early Cambrian.

  5. 5. Exceptionally Preserved Cambrian Lophotrochozoa : Taxonomy, Systematics and Taphonomy of Chengjiang and Indian Springs Lophophorates

    Author : Aodhán D. Butler; Michael Streng; Lars E. Holmer; Christian Skovsted; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Brachiopoda; Chengjiang; Lagerstätte; Cambrian Explosion; palaeobiology; stem-group; entoproct; phoronid; tommotiid; exceptional preservation.; Earth Science with specialization in Historical Geology and Palaeontology; Geovetenskap med inriktning mot historisk geologi och paleontologi;

    Abstract : The origin and evolution of Lophotrochozoa can be traced to the plethora of lower Cambrian scleritome taxa.  We aim to determine the character suites linking these stem-Lophotrochozoa to their extant crown relatives, in particular the small shelly tommotiids and the stem-group brachiopods.
