  2. 6. Ontogenetic scaling and the development of within-cohort size structure

    Author : Magnus Huss; Lennart Persson; Pär Byström; David Post; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cannibalism; competition; density-dependence; resource feedbacks; hatching; growth; ontogenetic niche shifts; Perca fluviatilis; size variation; larval fish; Freshwater ecology; Limnisk ekologi; zooekologi; Animal Ecology;

    Abstract : It is increasingly recognized that individuals of the same species differ from each other and influence and respond to their environment in unique ways. This thesis deals with size variation among individuals that not only are of the same species but also of similar age. READ MORE

  4. 7. Development and maintenance of quality indicators in pheasants

    Author : Thomas Ohlsson; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PHA; ELISA; immunocompetence; carotenoid coloration; male ornaments; fluctuating asymmetry; growth; early development; Phasianus colchicus; egg size; sexual selection; Animal ecology; Djurekologi; Ecology; Ekologi;

    Abstract : Females often base their choice of mates on the expression, size or intensity, of male sexual ornaments. Indicator models of sexual selection assume that females assess male genetic quality through the expression of these secondary sexual characters. READ MORE

  5. 8. Biology, ecology and anthropogenic threats of Indo-Pacific bottlenose dolphins in east Africa

    Author : Omar A. Amir; Per Berggren; Graham Pierce; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Growth; reproduction; feeding ecology; bycatch; organohalogen compounds; dolphins; Tursiops aduncus; Zanzibar; East Africa; Marine ecology; Marin ekologi; zoologisk ekologi; Animal Ecology;

    Abstract : This thesis examines the biology, ecology and anthropogenic threats of Indo-Pacific bottlenose dolphins (Tursiops aduncus) off Zanzibar, Tanzania, based on research conducted and samples collected between 2000 and 2008. Distribution and occurrence are described based on incidental catches (bycatch) in gillnet fisheries. READ MORE

  6. 9. Mechanics and Growth of Articular Cartilage Around a Localized Metal Implant

    Author : Krishnagoud Manda; Anders Eriksson; Nico Verdonschot; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; finite element analysis; articular cartilage defects; growth; knee; focal knee resurfacing; metal implant; poroelastic; porohyperelastic; biphasic;

    Abstract : Articular cartilage is a specialized connective soft tissue that resides on the ends of long-bones, and transfers the load smoothly between the bones in diarthrodial joints by providing almost frictionless, wear resistant sliding surfaces during joint articulation. Focal chondral or osteochondral defects in articular cartilage are common and show limited capacity for biological repair. READ MORE

  7. 10. A forage-only diet and reduced high intensity training distance in standardbred horses : growth, health and performance

    Author : Sara Ringmark; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : This thesis examined growth, health and performance in sixteen 1.5-3-year-old Standardbred horses fed a forage-only diet and trained to race as 3-year-olds in either a control training programme (C-group) or a training programme in which the high intensity training distance was reduced by 30% (R-group).
