  1. 1. Bacillus anthracis : naturliga utbrott, bioattacker och veterinärens roll

    University essay from SLU/Dept. of Biomedical Sciences and Veterinary Public Health

    Author : Olivia Nordfeldt; [2017]
    Keywords : Bacillus anthracis; antrax; biovapen; biologiska krigföring; bioterrorism;

    Abstract : Biologisk krigföring är inte ett nytt begrepp, tvärtom har forskare hittat mängder av exempel på sådana attacker redan från medeltiden, och ännu längre bakåt i tiden. Framväxten av den moderna mikrobiologin på 1900-talet, startade dock ett helt nytt kapitel och det var plötsligt möjligt att uppföröka stora mängder patogener. READ MORE

  2. 2. Shifts within the carbon cycle in response to the absence of keystone herbivore Ovibos moschatus in a high arctic mire

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Joel White; [2017]
    Keywords : vegetation; carbon; wetland.; methane; Arctic; Physical Geography Ecosystem Science; herbivory; Earth and Environmental Sciences;

    Abstract : Tundra ecosystems are generally recognized as globally important carbon sinks, yet the knowledge on threats to such ecosystems is narrow. Climate change is predicted to reduce the number of muskox (Ovibos moschatus) in the arctic, it is therefore essential to understand the effect herbivores induce on the arctic ecosystem. READ MORE

  3. 3. Risky places and risky times : vegetation cover and carnivore olfactory cues influence patch selection and antipredator behavior of African ungulates

    Keywords : predation risk; African ungulates; savanna; visibility; scats; Hluhluwe-iMfolozi; patch selection; large carnivore; hunting modes; vigilance; group size;

    Abstract : Foraging behaviour and vigilance of African ungulates are considered to be influenced by their perception of predation risk. In this experiment, I tried to obtain a better understanding of the relative importance of spatial and temporal drivers of perceived predation risk for African ungulates of various sizes. READ MORE

  4. 4. Perspectives of the human wildlife conflict situation from the standpoint of environmental justice : a case study of Hwange National Park, in Zimbabwe

    Keywords : environmental justice; human wildlife conflicts; wildlife;

    Abstract : Human wildlife conflicts in Zimbabwe have escalated due to human population growth which results in the expansion of settlements in areas close to national parks causing an overlap thereby causing clashes between humans and wildlife. Human wildlife conflicts are still a major problem in the country, mostly affecting people who rely on subsistence farming and livestock rearing. READ MORE

  5. 5. The repulsive shrub : impact of an invasive shrub on habitat selection by African large herbivores

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : David Rozen-Rechels; [2015]
    Keywords : invasive plants; large herbivores; savanna; habitat selection; clearing;

    Abstract : Invasive plants, growing and spreading outside of their native range, can severely modify ecosystems. Herbivory has often been seen as a potential control of invasions, but has rarely been considered as a potential impacted trophic level. READ MORE
