About this event

IAS Visiting Fellow Dr Alberto Doretto delivers a seminar on their research -

Siltation (i.e. the excessive accumulation of fine sediment on the riverbed) is globally recognized as one of the greatest impacts in lotic ecosystems due to the intensification of hydro-morphological (i.e. sediment flushing from dams) and land-use (i.e. deforestation, agriculture, urbanization) pressures. However, the ability to identify general cause-effect mechanisms of biological and morphological impairment are often limited by the context-dependency of individual studies. This seminar will consider a range of different studies and experimental approaches dealing with the response of stream benthic macroinvertebrate communities to fine sediment deposition. The examples include Alpine streams in Northen Italy as well as lowland rivers in UK, thus highlighting parallels and contrasts in the response of macroinvertebrate communities to fine sediment pressure within two different geographical settings. These findings provide valuable insights into biomonitoring approaches including how to monitor the effects of anthropogenically induced siltation in streams.

Arrivals from 11.45am for a 12pm start. For those joining in-person, lunch will be served after the seminar from 1pm.

    Supreme Court ruling: Update on practical implications for staff, students and visitors to campus accessing toilet facilities

    Following the UK Supreme Court ruling that in the Equality Act 2010 ‘sex’ means biological sex and as such, workplaces need to provide single sex toilet facilities. The EHRC has provided interim guidance that organisations should continue to adhere to the Equality Act 2010 and ensure protection for all protected characteristics, including trans and non-binary people.

    Israel’s peace movement offers a ray of hope amid the pain of Gaza conflict

    The first thing I do when going back to Israel for a visit is go for a run. After more than two years abroad, it is a good opportunity to refamiliarise myself with the home I left to pursue my academic career more than eight years ago.
