  1. 1. Arbete med biologisk mångfald på Kungliga Djurgården : med fokus på rödlistade och invasiva arter

    University essay from SLU/Dept. of Ecology

    Author : Vanda Barkstedt; [2023]
    Keywords : biologisk mångfald; rödlistade arter; invasiva arter; skötselåtgärder; bekämpningsåtgärder; Kungliga Djurgården; Kungliga Djurgårdens förvaltning;

    Abstract : Fler och fler arter hotas av förändrad markanvändning, klimatförändringar, spridning av invasiva arter m.m. För att motverka den negativa utvecklingen har urbana grönområden blivit allt viktigare. READ MORE

  3. 2. Animal personality in ants : Does the red wood ant (Formica rufa) express personality traits?

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Malin Sjöberg; [2023]
    Keywords : Animal personality; Scototaxis; Formica rufa;

    Abstract : A recent theory within behavioural ecology suggests that some animal behaviour traits are consistent over time and over different contexts as part of an animals’ “personality”. Animal personality has generally been accepted within vertebrates, but the idea of invertebrates expressing personality has long been meet with scepticism. READ MORE

  4. 3. Body patterning and cognition in cephalopods - a literature review

    University essay from SLU/Dept. of Animal Environment and Health

    Author : Georgina Chu; [2023]
    Keywords : cephalopods; octopus; body patterning; colour alteration; chromatophores; pigment cells; cognition; learning and memory;

    Abstract : Cephalopods are a valuable model for studying the evolution of cognition due to their distinctive brain structure, organisation, and connectivity patterns compared to vertebrates. The development of large brains and behavioural complexities are believed to be triggered by evolutionary pressures stemming from factors like heightened predation, more demanding foraging conditions, and intense mating competition.

  5. 4. The evolutionary origins of consciousness

    University essay from Högskolan i Skövde/Institutionen för biovetenskap

    Author : Azadeh Karamali; [2023]
    Keywords : Phenomenal consciousness; evolutionary origin; animal consciousness; sentience;

    Abstract : Some unanswered questions about consciousness as a biological phenomenon lie in its evolutionary origin and distribution among living organisms. Which animals are conscious and when did consciousness appear in the history of life on earth? The purpose of this thesis is to shed light on these long-standing questions by reviewing the literature on the evolutionary approaches to the fundamental concept of phenomenal consciousness.

  6. 5. Turing's model for pattern formation

    University essay from KTH/Fysik

    Author : Oskar Forsström; Oskar Falgén Nikula; [2022]
    Keywords : Reaction-diffusion; Turing pattern; morphogen; Grier-Meinhardt; Schnakenberg; numerical analysis; minimum energy control;

    Abstract : In an attempt to describe how patterns emerge in biological systems, Alan Turing proposed a mathematical model encapsulating the properties of such processes. It details a partial differential equation governing the dynamics of two or more substances, called morphogens, reacting and diffusing in a specific manner, in turn generating what has now come to be denoted as Turing patterns.
