Description

Absorbotrophic mixotrophy

Photosynthesis, Botany

Selosse et al. 2017, Ecology Letters, 20: 246–263.
Absorbotrophic (=osmotrophic) mixotrophy: uptake of soluble organic matter found in the environment, e.g., low molecular-weight molecules (...

Accessory combs

Accessory combs are conspicuous intermembranellar ridges. The term was introduced by Campbell (1926); the alternative names “Begleitkämme” (Entz 1909b) and “crêtes adorales” (Laval-Peuto 1994)...

Adoral zone of membranelles

The adoral zone of membranelles is an orderly arrangement of membranelles around the peristomial field, terminating in the buccal cavity. The term was probably introduced by Bütschli (1887-1889)...

Alveoli

Taxonomy

Anisogamous

Life cycle

Sexual reproduction in which the gametes differ from each other morphologically. 

Antapex

Taxonomy

The posterior-most part of the cell. 

Antapical

Taxonomy

In Dinophyceae, the posterior pole of the cell.

Antapical plates

Taxonomy

In thecated Dinophyceae, the plates covering the posterior end of the cell, not in contact with the cingulum. 

Anterior

Taxonomy

The top part of the cell.

Apical

Taxonomy

The anterior pole of the cell. 

Apical pore complex (APC)

Taxonomy

This feature is located on the epitheca of many marine, armoured thecated Dinophyceae. It includes an apical pore plate (Po), which bears an apical pore (ap), and often times, small periferal...

Apical complex

Parasitology, Taxonomy

A cell invasion apparatus positioned near the anterior end of apicomplexan cells consisting primarily of a microtubular conoid, a polar ring and unique secretory organelles such as the rhoptries...

Apical groove

Taxonomy

see Apical structure complex (ASC)

Apical pore plate (APC)

Taxonomy

Part of the apical pore complex (APC). A feature located on the epitheca of many marine thecated Dinophyceae. 

Apical structure complex (ASC)

Taxonomy

The apical groove and adjacent rows of amphiesmal vesicles on the epicone. Also called the sulcal furrox or acrobase. This structure plays a central role in food uptake (predatory). The path of...

Armoured (thecated)

Taxonomy

Dinoflagellate species that have thecal plates of varying thickness and orientation in identifiable tabulation series. Often the plates are thickened or ornamented with reticulations, spines,...

Auxosome

Biogeography

Ecology

The descriptive and explanatory study of the spatial patterning of biodiversity.

Biotrophic

Symbiosis

Interspecific trophic interaction, mutualistic or parasitic, where the two partners stay alive.

Biotrophic mixotrophy

Symbiosis, Photosynthesis

Definition by Selosse et al. 2017, Ecology Letters, 20: 246–263.
Biotrophic (= symbiotic) mixotrophy: uptake of organic matter derived from interactions with other living organisms (‘...
