  2. 1. Effects of landscape patterns on small mammal abundance

    Author : Frauke Ecke; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Landscape Ecology; Landskapsekologi;

    Abstract : Several studies indicate a long-term decline in the numbers of voles in northern Fennoscandia. Altered land use and forest management practices have been proposed as possible causes of the decline. READ MORE

  4. 2. Population dynamics of small mammals in relation to habitat factors in natural and managed forests

    Author : Frauke Ecke; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Landscape Ecology; Landskapsekologi;

    Abstract : The influence of forest age and structural habitat factors on species richness and the population dynamics of small mammals were evaluated. Small mammals were monitored both in old-growth and in immature managed forests, and habitat factors were recorded. READ MORE

  5. 3. Large-scale simulation of neuronal systems

    Author : Mikael Djurfeldt; Örjan Ekeberg; Charles Peck; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap;

    Abstract : Biologically detailed computational models of large-scale neuronal networks have now become feasible due to the development of increasingly powerful massively parallel supercomputers. We report here about the methodology involved in simulation of very large neuronal networks. READ MORE

  6. 4. Genetic structure, demographic change and extinction dynamics in the collared lemming and woolly mammoth

    Author : Eleftheria Palkopoulou; Love Dalén; Richard Edward Green; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Systematic Zoology; zoologisk systematik och evolutionsforskning;

    Abstract : In light of current climate change it is critical to understand how different species have been affected in the past by well-known climatic events. In this thesis, DNA was retrieved from ancient material to study the population dynamics of two cold-adapted taxa that capture the extremes of body size range in mammals: the collared lemming (Dicrostonyx sp.

  7. 5. Effects of Dehydration and Blockade of the Renin-Angiotensin System in the One-humped Camel (Camelus dromedarius)

    Author : Mahmoud Al Haj; Fred Nyberg; Santi Spampinato; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Blood; biochemical analysis; catecholamine; colorimetric assay; cortisol; dehydration; dromedary camel; glutathione; hematological analysis; HPLC; insulin- like growth factor-1; losartan; plasma; receptors; radioimmunoassay; serum; Pharmaceutical Science; Farmaceutisk vetenskap;

    Abstract : The one-humped or the dromedarian camel is a pseudo-ruminant mammal, well adapted to the hot and dry climates of the desert. Its ability to withstand torrid heat and extreme desiccation is of paramount importance to its survival. READ MORE
