  1. 21. Investigating the use of olfactory cues to re-direct African savannah elephant pathways. A potential conflict mitigation tool.

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Vera Ruijs; [2023-06-30]
    Keywords : African savannah elephants – conflict mitigation – elephant pathways – human-elephant conflict – olfactory cues;

    Abstract : Human-elephant conflict resulting from, for example crop raiding behaviour, poses a significant threat to the conservation of African savannah elephants (Loxodonta africana). These conflicts can lead to fatalities in both humans and elephants. READ MORE

  3. 22. Estimating historic ranges of extinct scavenging birds from North America during the late Pleistocene using co-occurrence data from the fossil record

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Melissa Miranda; [2023-06-30]
    Keywords : Scavenging birds; Vultures; Co-occurrence Data; Range Estimates; Spatial Autoregressive Models; Co-extinction;

    Abstract : The aim of my study was to estimate and compare the historic range of nine scavenging birds from North America that went jointly extinct with their mammalian megafaunal prey in the Late Pleistocene. Although the severity and timing of their co-extinction are strongly correlated, there has been little analytical support in providing estimates for the possible geographic distribution of scavenging birds prior to the extinction event.

  4. 23. Role of androgen receptor signaling in the activation and differentiation of plasmacytoid dendritic cells

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Faiza Tahsin Rashid; [2023-06-27]
    Keywords : ;

    Abstract : Androgens are steroid hormones essential for the development and maintenance of male reproductive organs and secondary sexual characteristics. Plasmacytoid dendritic cells (pDCs) are immune cells that act as the first line of defense against viral infections. READ MORE

  5. 24. The bzzzt of frirends. Interspecific competition in Arctic plants for pollination services.

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Malin Olsson; [2023-06-27]
    Keywords : the Arctic; pollinator networks; competition; autonomous selfing; Arktis; pollinationsnätverk; konkurrens; autonom självpollinering;

    Abstract : The Arctic has a harsh environment that is challenging for the flora and fauna that inhabits the region. The ruling abiotic factors of the region results is a low species richness that creates a potential challenge for the region’s plant species. READ MORE

  6. 25. IDENTIFICATION OF ENVIRONMENTALLY RELEVANT BENTHIC FORAMINIFERA FROM THE SKAGERRAK FJORDS BY DEEP LEARNING IMAGE MODELING

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Marko Plavetic; [2023-06-26]
    Keywords : benthic foraminifera; deep learning; environmental monitoring; YOLOv7;

    Abstract : Over the several past decades, there has been increasing interest in using foraminifera as environmental indicators for coastal marine environments. As compared to macrofauna, which are currently used in environmental studies, foraminifera offer several distinct advantages as bioindicators, including short generation times, a high number of individuals per small sample volume, hard and durable tests with high preservation potential, and low cost of sample extraction.
