    Author : Felix Fridh; [2023]
    Keywords : chytridiomycosis; amphibians; fungi; fungus; thermal mismatch hypothesis; bufobufo; common toad; Batrachochytrium dendrobatidis; Bd;

    Abstract : Batrachochytrium dendrobatidis (Bd) is a fungus that causes chytridiomycosis in amphibians. This fungus is an invasive species that has spread all over the world and is causing mass deaths in many areas. Bd has an efficient life cycle which targets suitable hosts and causes disturbances in amphibian osmoregulation and eventually death. READ MORE

  3. 2. The use of environmental DNA (eDNA) in biological monitoring of the Natterjack toad (Epidalea calamita)

    University essay from Lunds universitet/Examensarbeten i biologi

    Author : Lærke Breum Blom; [2018]
    Keywords : Biology and Life Sciences;

    Abstract : Environmental DNA (eDNA) is a promising new tool in the field of conservation management, which can contribute to non-destructive species determination as well as improved data on species occurrence. Still, it is important to gain knowledge on how eDNA works compared to conventional monitoring methods in order to evaluate the detection efficiency. READ MORE

  4. 3. Planning green infrastructure using habitat modelling : a case study of the common toad in Lomma Municipality

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : William Walker; [2014]
    Keywords : adaption to climate change; green infrastructure; planning; ecosystem services; habitat model; common toad; Bufo bufo; Earth and Environmental Sciences;

    Abstract : For an ecosystem to be able to continue to provide important services to society, it must be able to adapt to change. As part of an ecosystem, the ability of a species to migrate in the landscape is vital for the adaption to change. A green infrastructure allows the movement of species in a landscape fragmented by human influenced land use. READ MORE
