  1. 1. INTEREST RATES AND VENTURE CAPITAL INVESTMENTS: Early evidence of the heterogeneous effects of rising interest rates across funding stages

    D-uppsats, Handelshögskolan i Stockholm/Institutionen för finansiell ekonomi

    Författare :Eric Persson; Johan Skantz; [2023]
    Nyckelord :Venture Capital Investments; VC; Monetary Policy; Interest Rates;

    Sammanfattning : This thesis examines the impact of rising central bank interest rates on European venture capital investment activity between 2016 and the first quarter of 2023. Using a comprehensive dataset of 32,832 funding rounds across different funding stages, we run a set of regressions to study the relationship between interest rates and VC investments measured by total invested amounts, number of rounds, and average round size.

  3. 2. Secrets of the Seeds : exploring the relationship between seed morphology and seed quality in Lepidium campestre, a novel oil crop for Northern Sweden

    Kandidat-uppsats, SLU/Dept. of Plant Breeding (from 130101)

    Författare :Ludvig Pettersson Landgren; [2023]
    Nyckelord :Lepidium campestre; field cress; oil crop; plant breeding; domestication; seed morphology; seed colour; seed analysis; Northern Sweden; glucosinolate;

    Sammanfattning : This study set out to explore relationships between seed morphology and qualitative traits in field cress, Lepidium campestre, with the goal of assisting the breeding process of this crop under domestication. A collection of seeds of L. campestre as well as related species was analysed for weight and size using a MARViN seed analyser. LÄS MER

  4. 3. The Effects of Climate Change on Zirben (Pinus cembra) Distribution in the Italian Alps

    Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Nicholas Asplin; [2023]
    Nyckelord :Pinus Cembra; Tree line; Tree line shift; Alps; Climate change; Earth and Environmental Sciences;

    Sammanfattning : Anthropogenic climate change has caused temperature increases all across the globe. Mountainous areas are among the most affected and are experiencing alarming rates of warming. Such rapid warming will have effects on alpine vegetation and their distribution throughout the alps. LÄS MER

  5. 4. Carabids as weed seed control agent : impact of soil cultivation on carabid weed seed regulation

    Master-uppsats, SLU/Dept. of Crop Production Ecology

    Författare :Ellen Dahlgren; [2023]
    Nyckelord :weed seed predation; weed seed bank regulation; weed seed predation strength; seed predation strength; carabid beetles; tillage; piecewise structural equation model;

    Sammanfattning : As weed seed predators, carabid beetles can regulate the weed seed bank within agricultural fields. Little is anyhow known about how weed seed bank regulation by carabids is affected by different tillage treatments with decreasing intensity, why this was here examined. LÄS MER

  7. 5. Hyggesfritt skogsbruk i boreal skog – tidsstudie och kostnader för föryngringsåtgärder vid luckhuggning i ett tallbestånd i Vätteskogen, Skinnskatteberg

    Kandidat-uppsats, SLU/School for Forest Management

    Författare :Niclas Segerfur; [2022]
    Nyckelord :markberedning; plantering; sådd;

    Sammanfattning : I Sverige är trakthyggesbruket den dominerande metoden inom skogsbruket, men intresset för hyggesfria alternativ ökar ständigt. Luckhuggning är en hyggesfri avverkningsmetod speciellt lämpad för pionjärträdslag som tall. LÄS MER
