Sequential hermaphroditism, where males change to females (protandry) or the reverse (protogyny), is widespread in animals and plants and can be an Evolutionarily Stable Strategy (ESS) if fecundity rises faster with age in the second sex. Sequential... Read More about Consequences of sex change for effective population size.

Persistence of environmental DNA in marine systems (2018)
Journal Article

As environmental DNA (eDNA) becomes an increasingly valuable resource for marine eco-system monitoring, understanding variation in its persistence across contrasting environments is critical. Here, we quantify the breakdown of macrobial eDNA over a s... Read More about Persistence of environmental DNA in marine systems.

Metabarcoding of shrimp stomach content: harnessing a natural sampler for fish biodiversity monitoring (2018)

Given their positioning and biological productivity, estuaries have long represented key providers of ecosystem services, and consequently remain under remarkable pressure from numerous forms of anthropogenic impact. The monitoring of fish communitie... Read More about Metabarcoding of shrimp stomach content: harnessing a natural sampler for fish biodiversity monitoring.

DNA metabarcoding unveils multi-scale trophic variation in a widespread coastal opportunist (2018)
Journal Article
Siegenthaler, A., Wangensteen, O., Benvenuto, C., Campos, J., & Mariani, S. (2019). DNA metabarcoding unveils multi-scale trophic variation in a widespread coastal opportunist. Molecular Ecology, 28(2), 232-249. https://doi.org/10.1111/mec.14886

A thorough understanding of ecological networks relies on comprehensive information on trophic relationships among species. Since unpicking the diet of many organisms is unattainable using traditional morphology-based approaches, the application of h...

Hidden diversity hampers conservation efforts in a highly impacted neotropical river system (2018)
Journal Article
Sales, N., Mariani, S., Salvador, G., Pessali, T., & Carvalho, D. (2018). Hidden diversity hampers conservation efforts in a highly impacted neotropical river system. Frontiers in Genetics, 9, #271. https://doi.org/10.3389/fgene.2018.00271

Neotropical Rivers host a highly diverse ichthyofauna, but taxonomic uncertainty prevents appropriate conservation measures. The Doce River Basin (DRB), lying within two Brazilian threatened hotspots (Atlantic Forest and Brazilian Savanna) in south-e...

Delineating conservation units is a fundamental step in recovery planning for endangered species. Yet, challenges remain in the application and validation of scientifically evaluated conservation units in management practice. The Canadian government...

Generic names and mislabelling conceal high species diversity in global fisheries markets (2018)
Journal Article
Cawthorn, D., Baillie, C., & Mariani, S. (2018). Generic names and mislabelling conceal high species diversity in global fisheries markets. Conservation Letters, 11(5), e12573. https://doi.org/10.1111/conl.12573

Consumers have the power to influence conservation of marine fishes by selectively purchasing sustainably-harvested species. Yet, this power is hindered by vague labelling and seafood fraud, which may mask market biodiversity and lead to inadvertent...
