Andreas Bruder (Co-Chair)
Andreas is a freshwater ecologist with a focus on functional biodiversity and ecosystem processes. He mainly uses detritus-based food webs in streams to study how these elements of ecosystems are interlinked and modified by anthropogenic change. He established a laboratory to study all aspects of the biodiversity, ecology and biogeography of aquatic hyphomycetes, a diverse but understudied group of freshwater saprobic fungi. He applies the knowledge gained from these studies in collaborative projects with stakeholders, for instance to develop functional bioindicators or knowledge on understudied organism groups. He’s also Co-Chair of the Freshwater Biodiversity Observation Network, a part of GEOBON.



Angélica María Batista-Morales
Angélica has a graduate degree in Biological Sciences from the Universidad Nacional de Colombia and an MSc in Biological Sciences at the Universidad de Los Andes, Colombia. Angelica does research in Ecology, Limnology, and Genetics. She currently works at the Alexander von Humboldt Biological Resources Research Institute as a researcher of freshwater ecology, in the Research program of monitoring and evaluation of biodiversity. She works in the design of protocols, programs, and indicators of aquatic biodiversity and ecosystems. She supports the national mercury research plan in the expert committee for biota monitoring of the Minamata Convention, and the national monitoring ecosystem program of Colombia. She is one of the Latin America coordinators for Freshwater BON (FWBON) - GEOBON. She is interested in deepening the role of the dendritic structure of river networks on their biodiversity, the use of eDNA to analyze metacommunities, restoration, ecological connectivity, and developing strategies from macroecology to address management.



Aventino Kasangaki
An Ugandan ecologist, conservationist, consultant and academic, Aventino’s ecology and conservation work focuses on the integrity of freshwater ecosystems especially on how humans impact aquatic ecosystems and development of monitoring tools for assessing these impacts. He is passionate about the ecosystem goods and services communities derive from aquatic habitats. Over the last 23 years Aventino has worked as a wildlife researcher, consultant and lecturer in various fields of ecology and conservation of freshwater systems in Uganda and neighbouring countries.  He has authored over 20 publications in peer reviewed journals and written several technical reports for various projects. Born 52 years ago in rural western Uganda, he continues to champion biodiversity research and conservation through community outreach, teaching and development of biodiversity indicators aimed at assessing attainment of sustainable development goals.



Craig Macadam
Following 11 years in the water industry as an Engineering technician, Environmental Policy Officer and Drinking Water Scientist and time as a Biodiversity Officer and independent Consultant, I now head up the Conservation team with Buglife – The Invertebrate Conservation Trust. I have been studying freshwater invertebrates, particularly mayflies, stoneflies and caddisflies (the ‘riverflies’) for over 30 years and regularly deliver training on the identification of freshwater invertebrates. My particular interests are the effects of climate change on riverfly populations, the life histories of mayfly and stonefly species, and various aspects of urban biodiversity. I am co-chair of the IUCN Mayflies, Stoneflies and Caddisflies Specialist Group, a founder member of the Riverfly Partnership, a fellow of the Freshwater Biological Association, and a Scientific Associate of the Natural History Museum, London.



James Stribling
I am an aquatic ecologist with Tetra Tech, Inc.’s Center for Ecological Sciences, Owings Mills, Maryland, USA. I have >30 years of experience in developing aquatic monitoring and assessment datasets for use in environmental management decision-making. Much of my work has been assisting with continuous implementation of the United States’ Clean Water Act, using indicators of biological and ecological integrity as objective statements of ecological health. My academic background is in insect taxonomy and phylogenetic systematics, though in recent years have focused on developing a framework and procedures for defining data quality and performance measures. I developed an objective approach for quantifying taxonomic identification error rates associated with benthic macroinvertebrate data in monitoring and assessment datasets, and have been leading quality control (QC) analyses for the US Environmental Protection Agency in most of its National Aquatic Resources Surveys (NARS) since 2004.


Jennifer Lento
Dr. Jennifer Lento is a Research Scientist with the Canadian Rivers Institute at the University of New Brunswick (Fredericton, Canada).

She is also a co-chair of the Freshwater Biodiversity Observation Network (FW BON). Her research focuses on patterns in biodiversity and ecological function of freshwater food webs, particularly benthic macroinvertebrates. Her research evaluates structural and functional biotic responses to natural drivers and anthropogenic stressors as a way to inform practical applications of biomonitoring, including the development of biomonitoring designs and testing of appropriate biotic response metrics. Through her Arctic research, she has worked on developing and promoting harmonized sample collection and large-scale coordination of biodiversity assessment.

Nick Rivers-Moore
With a PhD in environmental hydrology, and as an established researcher and consulting aquatic ecologist, I have built up extensive expertise and professional experience working in river systems over the past 20 years. My research interests primarily focus on the field of environmental hydrology, where I have applied my skills across disciplines including freshwater conservation planning; climate change; ecological modelling; pest blackfly and trout ecology; and catchment-level predictions of wetland occurrence, types and ecological condition. A core research area for the past 15 years has been on river ecology and blackfly dynamics, where I have published work on system switches (clear to turbid conditions) and how this promotes pest outbreaks. I have considerable experience in fish and aquatic macroinvertebrate sampling, and collection and analysis of water temperature data, facilitated through a suite of metrics I developed to assess changes in magnitudes, frequency, duration and timing of thermal stress events. These skills are complemented by extensive experience in water temperature modelling, and development of ecological response models based on flow and water temperature inputs, also applied in climate change scenario impacts. I am currently co-editor for the African Journal of Aquatic Science, and subject editor for Water SA.
