Abstract:
In many tropical areas one of the main drivers of biodiversity loss is the degradation and fragmentation of pristine habitats. Different species cope differently with environmental stressors and some survive better than others. In cooperatively breeding species, subordinates provide extra care and/or protect a brood against predators. Breeding females of these species can apply multiple pre- and post-hatching strategies to optimize the trade-off between current and future reproduction. Such female behavioural plasticity may buffer natural variation in critical resources and thus in habitat quality. For instance, investment in offspring can be increased under harsh conditions, or alternatively, decreased when times are benign to benefit the breeding female. To what extent human-induced environmental change may trigger plastic maternal strategies in cooperative breeders, however, remains unclear. We study how habitat fragmentation affects breeding behavior, i.e. egg investment and nestling provisioning, and reproductive success, i.e. fledging success, of wild populations of Placid Greenbuls (Phyllastrephus placidus) - a forest specialist bird species that breeds in the cloud forest remnants of the Taita Hills of Kenya that are part of the Eastern Afromontane Biodiversity Hotspot. We study different populations of greenbuls that live in forest fragments varying in habitat size and quality ranging from large, undisturbed to small degraded patches. We hypothesize that females adjust their investment in eggs and nestlings depending on number of helpers and habitat quality. Thereby cooperative breeding may mitigate the negative effects of habitat degradation.

After the seminar (ca. 16:00 h), everybody is welcome to join us for drinks and munchies in the „coffee corner on the second floor“.

    Ingrid Vukusic and Georg Zimmermann were awarded the Hans-Stegbuchner Prize for outstanding scientific work in the Department of Mathematics at the University of Salzburg on the 19th November 2020.
    Prof. Tuulia Ortner, Prof. Hannes Winner, Prof. Norbert Christian Wolf und Prof. Michael Zichy were awarded the Kurt-Zopf Prize for the year 2019. This award honours high-ranking and internationally recognised publications from scientists at the University of Salzburg.
    The Paris Lodron University of Salzburg has launched an in-house mentoring program for new students as part of the “On Track” project. And it has come at the right time, because the lockdown has made the start of their studies into a real challenge for many first-semester students.
    The recording of the PLUS Talks "Studies and Teaching WS 2020/21“ from 25.11.2020 is now available.

    24 very easy exercises on 24 cards can be found in the SALTO advent calendar. The exercise ideas are ideal for children from the age of three and are also easy for the whole family to carry out in a small space. With the support of the Kinder Büro (Children's Office), this combinable contribution should benefit as many as possible.
    Researchers led by Salzburg's geoinformatics scientist Christian Neuwirth had already developed and presented a mathematical model for Covid-19 in May 2020 which examines the question of how long and intensively social distancing measures have to be maintained in order to reduce corona deaths further.
    Results of the study on media use by children and families during lockdown. Home schooling could be improved, but is on the right track. Secondary schools have a better profile. Families have learned to deal with lockdown and homeschooling.
    Digitization has led to an enormous spread of different forms of mobile working. Corona has brought an additional boost and has introduced home office in areas and for activities that were previously unimaginable.
    During the time of Corona, in particular, it became clear just how important it is to support students digitally in their every day university life. The project „On Track“ – stay on track combines digital and social worlds. It is starting at the right time!
