General

My group and I research how ecological and evolutionary processes interact to determine the fluctuations of populations. Within this context we focus on identifying the population consequences of variation in the expression of polymorphisms (genetic colour polymorphism in Eleonora's falcon [Laura Gangoso]) en polyphenisms (alternative male reproductive strategies [Tom van den Beuken, Flor Rhebergen] and dispersal polyphenism in bulb mites [Jacques Deere, Kat Stewart]) induced by e.g. environmental change or harvesting. To develop and test our hypotheses we use laboratory experiments on mites, statistical analysis of data and the construction and analysis of mathematical models. We recently applied our methods to field data on threatened populations of reef manta rays to analyse the population consequences of overfishing, and are also applying the models to the bioturbator Orchestia gammarellus in collaboration with Matty Berg (VU). On these webpages you can find out who we are and what we work on.

Information for students:

The alumni page provides an overview of previous student projects. Please contact me if you are interested in doing a research project on behavioural ecology, population biology, demography, either using experimental methods or theoretical tools (or both). 

The DynaMite research group consists of a diverse group of biologists that are interested in range of topics that include behavioural ecology, eco-evolutionary dynamics, life history theory, energy budget theory, and demography. Below you will find all group members.

Isabel Smallegange (group leader)

My research aims at developing a mechanistic framework to link ecology and evolution on the basis of the processes that drive the dynamics of heritable life history traits. I focus on understanding the maintenance and evolution of male dimorphism and the role of harvesting and environmental change in experimental and field populations. FUNDING: MacGillavry Fellowship (2013 - 2018), MEERVOUD (2014 - 2018) and VIDI (2015 - 2020) (NWO).

 

Jacques Deere (Post Doc)

Jacques investigates, using the bulb mite ( Rhizoglyphus robini) as a study species, the influence of dispersal propensity on population size and structure, life histories and how these change with stochastic environments.

Kathryn (Kat) Stewart (Post Doc)

Kat investigates how alternative mating tactics arise and are maintained within species, employing experimental approaches that incorporate environmental and demographic parameters with population genetics. Her research interests pivot around the origins and maintenance of biodiversity from the level of local adaptation and limiting gene flow in single landscapes, through the genetics of entire species' ranges, to understanding the causes of diversification of entire clades. FUNDING: VIDI Fellowship (awarded to I.M. Smallegange).

Laura Gangoso (Post Doc)

Laura has a Marie Curie Fellowship, is based in the group of Willem Bouten and also collaborates with Isabel. In her Post Doc she studies the ecological and evolutionary consequences of predator-prey phenological match-mismatch driven by climate change using Eleonora's falcon as a study system. Interestingly, Eleonora's falcon has a genetically determined colour polymorphism that covaries with behavioural traits and, together with Isabel, she will explore the eco-evolutionary dynamics of variation in this colour polymorphism using integral projection models.

Tom van den Beuken (PhD student)

Many species exhibit two discrete male morphs: fighters and sneakers. Fighters are large and possess weapons that they use to kill rival males. Sneakers are small without weapons but can sneak matings. Tom's PhD research focuses on finding out why such discrete morphs can coexist in single populations and what drivers underlie the expression of such dimorphisms. FUNDING: MacGillavry Fellowship (awarded to I.M. Smallegange).

 

 

Flor Rhebergen (PhD student)

A PhD project by Flor Rhebergen investigating how harvesting and environmental variability affect the joint dynamics of life history traits and population biomass dynamics of 'fast' Rhizoglyphus robini and 'slow' Naiadacarus arboricola populations in the lab and in the field. FUNDING: VIDI Fellowship (awarded to I.M. Smallegange).

And in 2017 we have many students working in the lab:

  • Chris Duinmeijer, working on sperm competition in the bulb mite (supervisor: Tom van den Beuken)
  • Naomi Eeltink, working on a cross-level test of the DEB-IPM (supervisor: Isabel Smallegange)
  • Hidde de Graaff, working on male morph expression in relation to competition in the bulb mite (supervisor: Flor Rhebergen)
  • Charlotte Gredall, testing life history theory using the bulb mite (supervisor: Flor Rhebergen)
  • Felicia Rook, literature review on foraging behaviour in great apes (supervisors: Isabel Smallegange & Karline Janmaat)
  • Logan Stockwell, working on cannibalism in the bulb mite (supervisor: Tom van den Beuken)
  • Dapnhe Vink, literature review on eco-evolutionary feedbacks in single populations (supervisor: Isabel Smallegange)

23 november 2017 presenteert De Amsterdamse Academie (DAA) zich om 16.00 uur in Voxpop op het BG-terrein.

De medezeggenschapsvereniging De Amsterdamse Academie wil actief deelnemen aan ondernemingsraden van de UvA op een kritische en constructieve wijze. Zij wil hiermee een alternatief bieden voor de verkiezingslijsten die ontstaan zijn naar aanleiding van de Maagdenhuisbezetting van 2015 en de traditionele vakbondslijsten. In 2018 zullen nieuwe verkiezingen plaatsvinden. De Amsterdamse Academie wil in alle faculteiten aan deze verkiezingen deelnemen. Zie ook het bericht in Folia.

In het (zelfbenoemde) oprichtingsbestuur van DAA zitten (vlnr) Han van der Maas (lid), Cees Kleverlaan (secretaris), Isabel Smallegange (penningmeester), Gerwin van der Pol (voorzitter), en Annemie Ploeger (lid).

6-10 November 2017

Transmitting Science organised another great course on understanding and constructing integral projection models.

October 2017: new paper out!

Jacques' paper on how dispersal expression affects natal population growth and structure has now been accepted by Ecological Modelling. Congratulations!

.

June 2017: new paper out!

The student projects of Rianne Fernandes and Jasper Croll are now published in Oikos. Great work!

.

June 2017: DynaMite goes on tour! NVTB meeting 2017, 1-2 June.

Come join us at the mite-modelling-mini-session at the annual meeting of the Dutch society of theoretical biology. Both Jacques Deere and Isabel Smallegange will talk about integral projection models parameterised for mites. The keynote speaker, Willem Bouten, will also touch upon this topic!

May 2017

David Reznick from UC Riverside and the leading PI on the Trinidadian guppy project came to visit IBED, and also the DynaMite lab.

Jan 2017: Laura Gangoso has been awarded a Marie Curie Fellowship!

Laura will be based in the group of Willem Bouten at IBED/UvA and will start her Fellowship later this year. She will be working on the ecological and evolutionary consequences of predator-prey phenological match-mismatch driven by climate change using Eleonora's falcon as a study system. For part of her project she will work with us to construct an integral projection model for this species, which has a genetically based colour polymorphism. Exciting!

Jan 2017: a warm welcome to Kathryn Stewart!

Kat just travelled halfway across the globe from Shanghai to Amsterdam to start a 2-year post doc on the genetics of eco-evolutionary dynamics. She has a strong background in genetics, and we welcome her expertise! 

Eco-evolutionary symposium at ESEB 2017 (20-25 Aug)

Jacques Deere, along with four other including Martijn Egas from IBED, are organising a symposium on eco-evolutionary dynamics at the ESEB Congress in Groningen. Keynote speakers are: Jen Schweitzer, Jonathan Pruitt, Isabel Smallegange and Andrew Hendry. Come join us at ESEB!
