Gender equality in marine science? Not yet…

Gender equality is an unavoidable topic that has been defined as a United Nations goal for 2030 , along with women empowerment. Gender equality ensures that everyone has the same rights and responsibilities, with the same opportunities and resources, without preferential treatment according to gender. The question of gender equality has been raised in research for several years. At the CNRS, a French scientific research organization, since 2013, an analysis has been made of gender parity in the mathematics community, for example. But biology attracts more women than men, compared to other sciences (Anneke et al., 2019). What’s the current scenario of the presence of women in marine biology research? Unsurprisingly, many studies prove that it is far from a given. In particular, a team of 11 female researchers from around the world showed that gender biases are real and persistent (Giakoumi et al., 2021).


Researcher Sylvaine Giakoumi and her 10 co-authors conducted a study on the presence and visibility of women in the natural sciences in several research institutions in the European Union, with no possibility of distinguishing between positions in marine biology. The CNRS (Centre National de Recherche Scientifique) in France, the CSIC (Consejo Superior de Investigaciones CientĂ­ficas – Superior Council of Scientific Research) in Spain and the Academia in Italy reported the proportions of men and women employed at different career levels*. While women slightly outnumber men in doctoral and post-doctoral positions (short term contracts), the trend is clearly reversed for permanent research positions. And the higher the hierarchical level, the fewer women there are in these positions (Fig. 1). These results agree with many other marine-related studies (Arismendi and Penaluna, 2016; Shellock et al., 2022; Legg et al., 2023). This raises the question of why women, who are equally numerous at the beginning of their doctoral studies, have a harder time obtaining a research position in Europe and do not move up the ladder afterwards. Eaton et al. (2020) have shown gender and ethnic biases in recruitment, which probably contribute to this trend.

Giakoumi et al. (2021) also analyzed scientific publications’ authorship of EU researchers in marine biology. They showed that women are less often present as first authors of publications**, especially in prestigious journals. These results are found worldwide and globally in biology and (Holman et al., 2016; Bendels et al., 2018). Ahmadia et al. (2021) found similar results in coral science papers both within and outside of OECD (Organization for Economic Cooperation and Development) countries. Women also receive fewer research grants (Giakoumi et al., 2021).

While these results are real and confirmed by multiple publications, the novelty of this article lies in the analysis of gender bias made by the authors. They asked researchers how they perceived the under-representation of women. They sent questionnaires to many researchers around the world and processed the answers, analyzing the answers of men and women. One surprising point is the number of respondents per gender. There were only 25% male respondents, although there are more male in the research field. This is a finding in itself: it seems that men take less time to respond to a gender survey than women (Giakoumi et al., 2021). And looking at the responses, it turns out that regardless of the question asked, men feel less gender inequality (Fig. 2), whether it is in the number of positions, publication in journals, or even their ability to obtain research grants.

The presence of women is minor in decision-making positions in marine biology, even though their leadership has been shown to lead to greater efficiency and more innovative measures in marine research (Blyhte and Cvitanovic, 2020). It has also been shown that various options could be implemented to increase the presence of women in marine biology research (Johannesen et al. 2022), and in biology in general. For example, Shellock et al. (2023) propose solutions based on the experience of women leaders in marine biology to increase the proportion of women in biology research. These solutions need to be adapted to the country and the cultural and political environment. For the sake of the oceans and their preservation, things must change, and women must have the same opportunities to reach positions of responsibility as men, based on skills and not gender. It should also be remembered that gender bias is compounded by nationality, ethnicity and age, making access to research even more difficult for some people.

*As female and male genders are the only ones available in the databases of the various European institutions, the authors were unable to include the other genders.

**The first author of a scientific publication is often the person who conducted the study and wrote the article. The other authors are named in order of contribution to the research. In some occasions (not always) the last author is the supervisor of the work.
