Loiseau Nicolas


I am an ecologist of marine communities. My primary research interests have been consistently focused on contributing to a better understanding of variability in coral reef fish biodiversity.  Specifically, my long-term research goal is to bring together innovative field-survey tools and computing methods in order to uncover the extent of marine diversity. Beyond these practical applications, my research has aimed to investigate theoretical questions regarding the properties and performance of diversity indices. In these ways, my research has centred on and continues to centre on a variety of themes, including: 

 -  the spatio-temporel patterns of coral reef fish communities

 - quantitative ecology

 - development of autonomous underwater video sampling​

PhD student at CRIOBE (Perpignan)

My research interests include macroecology, community ecology, functional ecology and conservation. During my PhD I will quantify ecosystem functions, provided by reef fish and investigate their effect on the resilience of coral reef ecosystems.

I am based at the GEOMAR Helmholtz Centre for Ocean Research Kiel in Germany, and also affiliated to the University of Kiel and the Smithsonian Tropical Research Institute in Panama.

Recent evolutionary radiations such as Darwin’s finches, East African cichlids or Heliconius butterflies have served as model systems to understand how novel variation and new species arise. These systems, clearly in the early stages of divergence, have stimulated research into the behavioral, ecological, and genetic bases of reproductive isolation that have arguably transformed our understanding of the origins of biodiversity. However, no analogous classic radiation comes to mind in the largest ecosystem on earth, the ocean. The overarching goal of our research is to develop the hamlets (Hypoplectrus spp, Serranidae, photographs below), simultaneously hermaphroditic reef fishes from the wider Caribbean, into a model system for the study of marine speciation.

The hamlets are diverse, with a variety of color patterns and geographic distributions that provide the opportunity to repeat comparisons both taxonomically and geographically. They encapsulate the entire spectrum of divergence, from genomic similarity to well-diverged species. Mate choice and spawning can be directly observed in the field throughout the year, providing a handle on reproductive isolation which surpasses nearly any other marine group for the sheer number and quality of behavioral observations that can be made in natural populations. Color pattern has been identified as an important ecological trait that is also used for mate choice, and specific hypotheses regarding the role played by natural and sexual selection in speciation have been developed. Finally, a number of genomic resources are available for the group.
