Taxonomy of the Haploporinae Nicoll, 1914 and Bunocotylinae Dollfus, 1950 (Digenea) from Mediterranean mullets (Teleostei): morphological and molecular approaches
The thesis aimed at developing a modern taxonomic framework of two major groups of mullet digeneans, the subfamily Bunocotylinae of the Hemiuridae and the subfamily Haploporinae of the Haploporidae, by combining morphological and molecular data. Saturnius is revised, three new species are described: S. minutus n. sp., S. dimitrovi n. sp. and S. overstreeti n. sp.; S. papernai is redescribed, a new diagnosis and a key to the species is provided. A taxonomic revision of the Mediterranean haploporid genera Haploporus, Dicrogaster, Forticulcita, Lecithobotrys and Saccocoelium was carried out. New generic diagnoses are provided for all genera. Haploporus and Lecithobotrys are considered monotypi…
Beyond counting species : a new way to look at biodiversity
In modern ecology, the traditional diversity indices (usually of richness, abundance, and species evenness) have been highly revealing and useful for monitoring community and ecosystem processes. However, around two decades ago, a pioneering research team noticed that these indices did not completely resolve their open questions. Thus, they suggested changing the way biodiversity was measured. At its base, this new methodology considers the distance between species (in phylogenetic or functional terms) before subsequently applying the appropriate biodiversity indices. Including phylogenetic and functional elements in the evaluation of diversity allows us to approach the concept of biodivers…
