Key research themes
1. How have diatom studies evolved in Brazil and what are the current gaps in understanding their biodiversity and ecological roles?
This theme investigates the historical progression, geographic distribution, and focus areas of diatom research in Brazil, emphasizing gaps in taxonomic knowledge and geographic sampling bias. It matters because diatoms play crucial roles in aquatic ecosystems as primary producers and bioindicators, yet their full biodiversity and ecological functions remain underexplored in many Brazilian regions, especially in semi-arid and northern areas.
2. What are the ecological characteristics and species composition of coastal reef fish communities in southern Brazil?
Research under this theme focuses on quantifying species richness, abundance, and community structure of reef fish assemblages inhabiting rocky islands off the coast of Santa Catarina in southern Brazil. Understanding these aspects is critical for managing biodiversity hotspots, informing conservation strategies, and sustaining fisheries in coastal marine ecosystems.
3. What evidence exists on the distribution and biology of the little-known medusa Drymonema dalmatinum in the Adriatic Sea and Mediterranean?
This theme addresses the rarity, historical observations, recent sightings, and morphological characterization of Drymonema dalmatinum—a large scyphozoan jellyfish—in the Adriatic and wider Mediterranean Sea. Understanding its distribution and ecological role is significant given its size, rarity, and taxonomic distinctiveness, contributing to marine biodiversity knowledge and potential ecosystem impact assessments.
