Amphibian diseases

Minimaliseren

Emerging infectious diseases have become an important factor in global amphibian declines. The Netherlands are no exception and a multitude of species and communities have been affected by these pathogens. Reptile, Amphibian and Fish Conservation the Netherlands is conducting several studies concerning infectious diseases and parasites.

ITEM: AMPHIBIANS

  • Disappearing rate in amphibian populations
    When you find one dead frog it often means that more dead frogs are likely in the area. But how many more? This is just question that we would like to explore. This is essential information for how disease outbreaks behave in terms of mortality rates in time and space. We are looking for an intern that that can design a study to answer this question and can also conduct (part) of the study.

    LEVEL: BSc or MSc student
    EXTENT OF THE INTERNSHIP: Design study (fall, winter and early spring), fieldwork (spring, summer, early fall)
    SUPERVISORS: Annemarieke Spitzen

ITEM: AMPHIBIOCYSTIDIUM

  • Monitoring Amphibiocystidium in the Netherlands
    To date we know little about the effects of the amphibian parasite Amphibiocystidium on individual amphibian species and amphibian communities. This disease can manifest itself als small lesions and/or bloat. In the Netherlands there are several regions where this disease is known to be prevalent. We would like to investigate what the effects are on amphibian communities and especially on palmate newt populations in the long term.

    LEVEL: BSc or MSc student
    EXTENT OF THE INTERNSHIP: 4-5 months
    START DATE: February/ June 
    SUPERVISORS: Annemarieke Spitzen, Tariq Stark

ITEM: RANAVIRUS

  • Recently several outbreak of Ranavirus have occurred which resulted in thousands of dead amphibians. It is unknown what the long term effects are on amphibian communities. In collaboration with the Dutch Wildlife Health center we would like to monitor two outbreak locations during an entire field season.

    LEVEL: BSc or MSc student
    EXTENT OF THE INTERNSHIP: 7-8 months
    START DATE: February / October
    SUPERVISORS: Annemarieke Spitzen (RAVON) & DWHC (www.DWHC.nl)

ITEM: Batrachochytrium salamandrivorans

  • Fire salamanders and Batrachochytrium salamandrivorans
    In 2010 Fire salamander populations collapsed entirely. Currently the populations have been reduced to 99.9 % of their former numbers. We have learned that a novel fungal disease was the root cause of these dramatic population declines. In order to learn more about the developments post population collapse we need to study and monitor these populations. Does reproduction still take place, does water quality have an effect and what are the current population dynamics?

    LEVEL: BSc or MSc student
    EXTENT OF THE INTERNSHIP: 7-8 months
    START DATE: January / August 
    SUPERVISORS: Wilbert Bosman and Annemarieke Spitzen
