About

I'm a professor of Animal Behaviour, studying and teaching animal behaviour in the context of ecology and evolution. My main research interest has always been to understand behavioural and other adaptations to breed successfully - how evolution and ecology has shaped what the animals do as partners and parents, what they look like, and how they allocate their resources through life. Central topics of my research include sexual selection, parental care, and life history. Currently, I study how such processes are affected by variation in climate. I teach on these same topics, on animal behaviour broadly, and on the methods of doing science. I have also been extensively engaged in dissemination of science to the general public, and have regularly engaged in public discourse on science.

My research has been published in a range of international scientific journals, including major journals of ecology (e.g. Ecology, Journal of Animal Ecology, American Naturalist), evolution (e.g. Evolution, Journal of Evolutionary Biology, Trends in Ecology and Evolution) and animal behaviour (e.g. Behavioral Ecology, Animal Behaviour), as well as the broader-scope journals Nature, PNAS and Proceedings of the Royal Society B. I have also co-edited an international book on Animal Signaling, along with former NTNU colleagues Yngve Espmark and Gunilla Rosenqvist.

While I love exploring nature's wonders in research, I equally much enjoy training the new generation of biologists through teaching and supervision, and to engage in dissemination of science and academic matters to the general public.

In 2019, I received the NTNU Public Dissemination of Science Award, and in 2022, I received, together with my co-manager Aline M. Lee and a team of dedicated teachers, the Faculty of Natural Sciences Outstanding Pedagogical Activity Award for the upgrade of the course BI1003 Ecology, Behaviour and Evolution. My research has been reported in major media general and popular science outlets around the World, including New York Times, National Geographic, Scientific American and Science.

Research focus: diversity and dynamics of sexual selection in a changing climate

More or less throughout my whole life as a scientist, I have been been drawn to neglected or emerging fields, most notably the neglect of females in the study of sexual selection. In my research, I have challenged the traditional notion that sexual selection mainly forms male animals, and have contributed in studying how sexual selection may act also on females, and the female role in reproductive dynamics. In recent years, my main interest has been to understand the dynamical nature of sexual behaviours, sex roles and sexual selection - and the drivers of these dynamics and the variation in sexual behaviours we see in nature. Notably, 'sexual behaviours' in this context is not so much about the act of sex as such, but more about the behaviours that precede mating - courtship of the opposite sex, and competition with same-sex individuals, in both sexes. It is also about other traits of attraction in the mating game - beautiful colours, plumes, fins and other extravaganza - and it is about traits that help males and females win contests, like body size and condition.

In the current DYNAMAR project, we explore the connections between climate and sexual selection, using the Scandinavian coastline as a "natural climate laboratory".

Education and appointments

I have worked at NTNU (and its predecessor AVH) since 1991. Before that, I did my biology studies at the University of Oslo, including most of my PhD work. I was supervised for my MSc by professor Tore Slagsvold, and for the PhD by Slagsvold and professor Nils Christian Stenseth. I also have education in Environmental Science from former Telemark College (now University of South-East Norway). I have been a visiting researcher and conducted studies in a number of countries (primarily Norway, Sweden, Finland and Australia).

I very much enjoy doing science, but equally much to teach science to the next generation and to the general public. I greatly enjoy field work - the wonderful combination of experiencing nature while handling the intellectual and logistic challenges of studying biology IRL (in the wild, or sometimes in indoor experiments). I never stop being fascinated by the overwhelming diversity of nature that we are not even close to fully understanding.

Model organisms: birds and fishes

During the first half of my career, I mostly used birds as model organisms to investigate questions related to parental care, sexual selection and related topics. Study species included seabirds (e.g. European shags, Antarctic seabirds), woodland birds (titmice, pied flycatchers), and mountain birds (bluethroats). For the last few decades, I have turned to using fishes as model organisms. This is partly because of an interest and fascination for coastal ecosystems, and because we know so much less about marine than terrestrial life. But it is also because fishes offer opportunities for studying the dynamics of sexual selection, in the wild and in captivity, that cannot easily be achieved with, for instance, birds or mammals. Fishes are also the most diverse and dynamic in their styles of life among vertebrates, offering a plethora of mysteries to be resolved and a unique scope for investigations. Most of my fish work has used small marine goby fishes, in particular the two-spotted goby, as model organisms. I have also worked on coral reef fishes (damselfishes), aiming to contribute in understanding the reasons behind their splendid colours.

I am a member of the Marine Sciences Group of the Department of Biology.

Research

My  research  is  focused  on  the  evolutionary  understanding  of  animal  behaviour.  I  have  conducted  research  on  several  issues  related  to  parental  care  and  sexual  selection,  and  the  interplay  between  the  two  processes.  In  addressing  these  topics,   I  have  studied  a  wide  range  of  fish  and  bird  species.  My  current  research  is  focused  on  three  main  issues:  (1)  Sex  role  dynamics,  (2)  Female  ornamentation  in  relation  to  male  mate  choice  and  female‐female  competition,  and  (2)  Social  and  genetic  mating  systems;  all  of  these  relating  to  the  larger  issue  of  animal  signaling.  My  current  main  model  species  is  the  two‐spotted  goby  (Pomatoschistus  flavescens),  a  small  but  ecologically  important  marine  fish inhabiting shallow-water kelp and seaweed forests of the East Atlantic.  The  research is  focused  on  reproductive  dynamics,  including  behavioral  and  ecological  factors  that  promote  or  restrain  reproduction.  I  have  also studied related questions using coral  reef  fishes  as models, with a focus on their often splendid coloration, but recently also effects of coral bleaching and coral mortality on reef fishes. While the majority of my work has aimed to understand basic biological phenomena and processes, I am also involved in projects related to conservation biology and climate change.  My  research  involves  collaboration  with  specialists  around  the  world and researchers  at  our  NTNU  lab. 

The research of my lab has been funded by grants from the Research Council of Norway (main source of funding, FRIFORSK and MARINFORSK programs), EU and EEA grants (mobility, networking), the Nordic Council (Nordforsk, Nordic Marine Academy), the Royal Norwegian Society for Sciences and Letters (DKNVS), the Norwegian Academy of Science (DNVA), the Royal Swedish Academy of Science (KVA), and other sources.

FishDrone is a small-scale project to explore the use of simple underwater drones (ROVs) for efficient mapping of two-spotted goby prevalence by location and depth, supported by the DKNVS. The project was carried out in conjunction with ClimateFish.

Publications

Animal Signals: Signalling and Signal Design in Animal Communication

Together with colleagues Yngve Espmark and Gunilla Rosenqvist, I edited the book Animal Signals, based on contributions from leading scientists at a workshop with the same title and funded by the Royal Norwegian Society for Sciences and Letters (DKNVS).

Sex Roles and Sexual Selection: Lessons from a Dynamic Model System

This article summarizes what we have learnt by using the small goby fish Pomatoschistus flavescens as a model organism to understand reproductive dynamics in animals. It provides the foundation for our current work on climate and reproduction (DYNAMAR).

Why are Female Birds Ornamented?

This is by far my most cited article, on the much neglected field of sexual selection in females. Building on the history of sexual selection research, the article discussed empirical and theoretical advances and provided guidelines for future research.

I have published my research in major journals of science (Nature, PNAS), in leading journals of my research fields ecology (e.g. Ecology, Journal of Animal Ecology, Trends in Ecology and Evolution), evolution (e.g. Evolution, Journal of Evolution), and behaviour (e.g. Behavioral Ecology, Animal Behaviour). I have also published in specialized journals for the organisms I have studied (e.g. Journal of Avian Biology, Journal of Fish Biology) and their environments (Marine Biology, Coral Reefs).

I have also written essays and opinion pieces for major Norwegian newspapers (e.g. Aftenposten, Dagbladet), for science websites (e.g. forskning.no), and for NRK (nrk.no), and have often been interviewed by the same outlets, and many others, about my own and related research, and on broader matters of science or science controversies. I have often contributed to radio (NRK and other, many channels and programs) and sometimes to TV programs, reporting on own or related science, or debating/discussing in-focus or controversial science matters.

My research has been covered by a range of international newspapers (e.g. New York Times, The Independent, Folha de Sao Paulo), magazines (e.g. National Geographic) and web sites (e.g. ScienceNOW), as well as a wide variety of Norwegian outlets (local newspapers, magazines, web-based outlets).

Teaching

Courses

Teaching and supervision

I enjoy teaching and teach at all levels, from introductory undergraduate to PhD level. Topics for courses teach or have taught include general animal behaviour, communication and reproductive behaviour, sexual selection, and the theory and philosophy of biological science. I also enjoy supervising MSc and PhD students, and mentoring postdocs and researchers.

In 2020, I was the manager of a major upgrade of the first-year BI1003 Ecology, Behaviour & Evolution course (below), including pedagogical upgrades (a diversity of student-active learning tools and activities), improved topical integration, a new team of teachers, and introducing Global Environmental Challenges and Sustainability as an overarching theme for the course. I was supported by co-manager Aline M. Lee and an excellent team of teachers. In 2021, Aline took over as main manager of the course.

In 2022, the BI1003 Team received the Outstanding Pedagogical Activity Award of the Faculty of Natural Sciences, NTNU, for the course revision implemented in 2020/21 (and later followed up), emphasizing sustainability, pedagogical diversity and student-active learning.

Main current courses

BI1003 Ecology, Behaviour og Evolution

First-year course in evolution, behaviour and ecology - the very first biology course in the study program of the Department. I am responsible for teaching behaviour, life history (and a bit evolution. The course is tought in Norwegian, and includes lectures and a supervised student group project on an assigned topic related to environmental challenges sustainability. The current (2022 onwards) main course manager is Associate Professor Aline M. Lee.

BI2045 Sexual Selection and Communication

This course explores communication, sexual selection and reproductive behaviour in animals. It fits into the curriculum towards the end of a BSc degree. The course is based on lectures and a supervised literature review project, and is taught in English. I am the manager and main teacher of the course.

A selection of courses previously taught (and developed)

How To Do Science

Introductory course for the MSc in biology. I am responsible for teaching Theory of Science. The course is taught in English. The course manager is Martin Wagner.

BI3052 Study Design

This MSc course aims to provide an extensive and hands-on introduction to good study design for MSc projects and in general. I developed the couurse along with professors Jon Wright and Christophe Pélabon. My part of the course was on "Testing Hypotheses in Science", "Experimental vs Observational Studies", and "Laboratory vs Field Studies". Currently, the course is taught (and updated) by a new team of teachers, but with the same overarching aims. The current course manager is Professor Cameron Ghalambor. The course is taught in English, and involves extensive student-teacher interaction and group assignments.

MN 8000 Doing science: methods, ethics and dissemination

This course provides a down-to-earth introduction to the fundamental issues of doing science - the challenges and potentials of the scientific endeavour. It also deals with contemporary controversial issues related to the interaction between science and society. I was once instrumental in initiating and developing this course, which to a large extent was modelled on my previous course BI8092 Theory of Science in Biology, for biology PhD students. The current BI8000 course is a PhD course that is mandatory for all PhD candidates at the Faculty of Natural Sciences and Technology (the "NT Faculty"), normally to be taken at the start of the PhD study. The course is intensive course and is taught during January - February. The course includes plenary sessions for all students (e.g. scientific writing, dissemination, history of science) and seminar sessions focusing on fundamental issues of doing science. These seminars are split by topic/department. I am responsible for the seminars for biology and biotechnology candidates (and potentially for biophysics). The current course manager is Professor Brian Grimes.

Supervision

I have extensive experience from supervising MSc and BSc projects, and from mentoring/hosting postdocs and researchers.

I currently supervise or host the following:

Ivain Martinossi, postdoc 2021-2025, DYNAMAR project (host)

Håvard Kaland, PhD candidate, NTNU Ålesund (co-supervisor, main supervisor: Grethe Hansen Aas).

Linn Amalie Sveen Aaresvik, MSc student Ocean Resources

Eirin Jetmundsen Eknes, MSc student Ocean Resources

Tilde Tveraa Røilid, MSc student Ocean Resources

(The PhD-students are co-supervised with Postdoc Ivain Martinossi as main supervisor)

Outreach

Outreach: important & enjoyable

I like communicating science to lay audiences, and do so through lectures, newspapers, magazines, radio, TV, etc, in Norway and internationally. In 2019, I received the NTNU Award for Excellence in Science Dissemination.

Artenes utryddelse (Samfundet, Trondheim)

A talk on the future on coral reefs, and debate on the threats to biodiversity, at a meeting on "Artenes utryddelse" (the Exctinction of Species) at the Student Union (Samfundet) in Trondheim. I have given related talks to a range of audiences.

Nordiske Mediedager: Om netthets og netthat

I was once invited to address "hatred on the web from a biological perspective", and was very close to turn down the invite, but then thought "maybe scope to teach some biology to a new audience" :-) and went for it... Nordiske Mediedager, Bergen.

"World record in mating"

When dissemination gets tabloid and headlines out of control: Having reported an exceptionally large ("World record?") goby brood to friends on Facebook, all sorts of media tapped in. First time for sexual selection on NRK news? (from about 13:30 in clip)
