Article
Full-text available
The South African coast is known to harbor four different species of intertidal oribatid mites and their distribution strongly correlates with marine ecoregions. Relatively little is known about the dispersal of these organisms and how populations of different locations are connected. To test dispersal abilities and connectivity of these South Afri...

Background Elasmoid scales are one of the most common dermal appendages and can be found in almost all species of bony fish differing greatly in their shape. Whilst the genetic underpinnings behind elasmoid scale development have been investigated, not much is known about the mechanisms involved in moulding of scales. To investigate the links betwe...

We investigated the epibiotic community along Cymodocea nodosa leaves in a seagrass meadow in the Northern Adriatic Sea. In accordance with previous studies, we found that autotrophic organisms dominated throughout the study period (May-October 2014) and showed a clear temporal occurrence pattern with highest occurrence frequencies during summertim...

Aim In the Mediterranean biodiversity hotspot, freshwater fishes are key biogeographic indicators, while their habitats are vulnerable to ongoing anthropogenic pressures. The freshwater blenny is a widespread endemic taxon in this area. However, our understanding of the overall diversity of specific populations and their phylogenetic relationships...

Background: Elasmoid scales are one of the most common dermal appendages and can be found in almost all species of bony fish differing greatly in their shape. Whilst the genetic underpinnings behind elasmoid scale development have been investigated, not much is known about the mechanisms involved in the shaping of scales. To investigate the links b...
Article
Beaches are good indicators for local microplastic distribution and pollution. Multiple methods have been developed for extracting microplastics from sediment through density separation. However, the chemicals applied are often expensive and harmful to the user or the environment. We briefly review the problems associated with the use of these chem...
Article
Full-text available
A comprehensive study of the intertidal oribatid mite fauna of southern Japanese islands revealed the presence of the selenoribatid Arotrobates granulatus Luxton, 1992 and two yet undescribed species. The latter are herein described as Indopacifica taiyo n. sp., occurring from the Southern to the Central Ryukyus, and Indopacifica tyida n. sp., whic...
Article
Full-text available
High-quality and complete reference genome assemblies are fundamental for the application of genomics to biology, disease, and biodiversity conservation. However, such assemblies are available for only a few non-microbial species1–4. To address this issue, the international Genome 10K (G10K) consortium5,6 has worked over a five-year period to evalu...
Article
Full-text available
The clingfish (Gobiesocidae) genus Gouania (Nardo 1833) is endemic to the Mediterranean Sea and inhabits, unlike any other vertebrate species in Europe, the harsh intertidal environment of gravel beaches. Following up on a previous phylogenetic study, we revise the diversity and taxonomy of this genus, by analysing a comprehensive set of morphologi...
Article
Full-text available
Otolith morphology is a widely accepted tool for species identification in teleost fish, but whether this holds true for very small species remains to be explored. Here, the saccular otoliths of the cryptobenthic Mediterranean clingfish Gouania (Gobiesocidae) are described for the first time. Our new data, although preliminary, indicate that otolit...

Beaches are good indicators for microplastic distribution and local microplastic pollution. Multiple methods have been developed for extracting microplastics from sediment, mainly through density separation. However, the chemicals applied are often expensive and harmful for the user or to the environment. We briefly review the problems associated w...
Article
Full-text available
Aim Population connectivity of benthic marine organisms depends strongly on planktonic larval dispersal and is controlled by geographic distance and oceanographic structure. We examine isolation by distance versus resistance to barriers (ocean current boundaries) against a background of post‐glacial habitat expansion in a small benthic fish of the...
Article
Full-text available
Growth patterns of the lesser Neptune grass, Cymodocea nodosa, and the distribution of epifauna and epiflora along its leaves were studied from May to October 2014 at two different depths (1.5 and 5 m) in the northern Adriatic Sea (Pula, Croatia). Generally, seagrass biomass, shoot density and number of leaves per shoot were higher in the shallow w...

Article
Full-text available
The Japanese islands represent one of the world's biodiversity hotspots. Their geological history and present geography resulted in a high number of endemic species in nearly all major metazoan clades. We investigated the phylogeography of three different intertidal mite species from the Ryukyu islands and southern mainland by means of morphometry...
Article
Full-text available
The Ameronothridae are recorded for the first time from Japanese coasts with the new species Ameronothrus yoichi sp. n. from Hokkaido. The report of this species represents the most southern occurrence of an Ameronothrus species in the Asian Pacific region. Ameronothrus yoichi sp. n. can be easily distinguished from its congeners by the conspicuous...

The Cornish sucker, Lepadogaster purpurea (Bonnaterre, 1788), a clingfish species thus far known from the north-eastern Atlantic south to western Africa, the Canary Islands and Madeira, and the western Mediterranean basin, was recently collected in Sicily (Italy), Croatia and Greece. Species identification was based on morphological and/or molecula...

Project
Main goals of this PhD-project are: 1) The taxonomical and systematical revision of the genus Gouania and a pan-mediterranean diversity screening. 2) To unncover the phylogenetic context of the Gouania radiation by applying (phylo-)genomics methods to the recently produced high-quality genomes. 3) Gaining insights into the microevolutionary processes leading to species formation by applying populations genetics and genomics. 4) To conduct studies on microhabitat association, morphological convergence and gut-content analyses.
Project
The goal of this project is to unite scientists that are currently working on Mediterranean clingfish diversity, ecology and evolution.
Project
I investigate the biology, biogeography, ecology and evolution of intertidal oribatid mites. Presently, I focus on the bio- and phylogeography of Caribbean intertidal mites.
