[email protected] Abstract Microbial interactions are crucial for Earth ecosystem function, yet our knowledge about them is limited and has so far mainly existed as scattered records. Here, we have surveyed the literature involving planktonic protist interactions and gathered the information in a manually curated Protist Interaction DAtabase (PIDA). In total, we have registered ~2,500 ecological interactions from ~500 publications, spanning the last 150 years.

Cyanobacteria Cyanobacteria, also known as blue-green algae, are microscopic organisms found in both marine and fresh water environments. Under favorable conditions of sunlight, temperature, and nutrient concentrations, cyanobacteria can form massive blooms that discolor the water and often result in a scums and floating mats on the water’s surface.

  • Highlights • the Type Species of Cochlodinium, C. Strangulatum, Is
    1 Highlights • The type species of Cochlodinium, C. strangulatum, is widespread, but was mistaken for large cells of Gyrodinium. • First molecular data of a Cochlodinium heterotrophic species, the generic type Cochlodinium strangulatum. • The morphology and molecular phylogeny of Cochlodinium polykrikoides is distantly related to the generic type. • New genus, Margalefidinium gen. nov., and combinations for Cochlodinium polykrikoides and allied species. 2 Molecular characterization and morphology of Cochlodinium strangulatum, the type species of Cochlodinium, and Margalefidinium gen. nov. for C. polykrikoides and allied species (Gymnodiniales, Dinophyceae) Fernando Gómeza,*, Mindy L.

Gómez) 3 ABSTRACT Photosynthetic species of the dinoflagellate genus Cochlodinium such as C. polykrikoides, one of the most harmful bloom-forming dinoflagellates, have been extensively investigated. Little is known about the heterotrophic forms of Cochlodinium, such as its type species, Cochlodinium strangulatum. This is an uncommon, large (~200 µm long), solitary, and phagotrophic species, with numerous refractile bodies, a central nucleus enclosed in a distinct perinuclear capsule, and a cell surface with fine longitudinal striae and a circular apical groove. The morphology of C. polykrikoides and allied species is different from the generic type. It is a bloom-forming species with single, two or four-celled chains, small cell size (25–40 µm long) with elongated chloroplasts arranged longitudinally and in parallel, anterior nucleus, eye-spot in the anterior dorsal side, and a cell surface smooth with U-shaped apical groove.

[email protected] Abstract.- The naked dinoflagellate Cochlodinium fulvescens was rarely observed in Bahía de La Paz since 2008. Sporadic observations were made in 2010 and 2012. The species re-appeared from October 2012 to April 2013. Abundance of C. fulvescens ranged from 600 to 45,800 cells L–1 during this period in seawater temperature at 22-27°C and salinity of 35.25- 35.75. This species appeared as single cells or two-celled chains and co-occurred with Cochlodinium polykrikoides at the end of the bloom.
