'''''Mayorella''''' is a [[genus (biology)|genus]] of small [[amoeboid]] [[protists]] in the phylum [[Amoebozoa]]. The genus consists of amoebae that exhibit [[pseudopodia]] and feed on a variety of organisms through [[phagocytosis]], making them an important group in [[microbial ecology]] across most environments worldwide. ''Mayorella'' species have been found in soil, freshwater and marine environments.<ref name="Mayorella marianaensis"/>
== Etymology ==
''Mayorella'' was named in the honor of [[Alfred G. Mayer|Alfred G. Mayor]], [[curator]] of [[natural sciences]] of the [[Brooklyn Institute of Arts and Sciences]], the founder and first director of the Tortugas Marine Laboratory where the author of the genus, {{ill|Asa Arthur Schaeffer|de}}, was working at the time of the genus' description in 1926.<ref name="Glotova et al. 2018"/>
== Characteristics and ecology ==
''Mayorella'' amoebae use [[protoplasmic streaming]] for their movement and feeding. Like many other amoebae, they feed on [[bacteria]], [[fungi]] and [[algae]] through [[phagocytosis]]. Their feeding promotes nutrient regeneration for the habitats, and regulates the populations of algae and bacteria. For this reason they are an important functional group in the [[ecology]] of worldwide [[microbial communities]], for which they gain increasing recognition.<ref name="Mayorella marianaensis"/>


Most species of ''Mayorella'' have been isolated from soil or freshwater environments, while a few have been reported from marine habitats, two of them from deep-sea areas.<ref name="Mayorella marianaensis"/>
'''''Mayorella''''' is a genus of [[Amoebozoa]].
== Classification ==
=== Taxonomic history ===
In 1926 the zoologist {{ill|Asa Arthur Schaeffer|de}} established the order ''Mayorella'' in the [[monotypic]] [[family (biology)|family]] '''Mayorellidae'''.<ref name="Schaeffer 1926"/> The taxonomic history of the genus was complex. Many amoebae had similar morphology to ''Mayorella'' had either a thick, multi-layered cell coat (or [[cuticle]]), or scales on the surface of the [[cell membrane]]. The zoologist Frederick C. Page created the genus ''[[Hollandella]]'' to gather all ''Mayorella''-like species with cuticle, but the type species of this genus had scales instead of a cuticle, so the genus was abandoned. The species with scales were instead placed under the genus ''[[Dactylamoeba]]'', which was later formally replaced with the name ''[[Korotnevella]]''.<ref name="Glotova et al. 2018"/>


The diversity of ''Mayorella''-like amoebae is high, but the distinction between species of the genus is difficult and requires [[electron microscopy]] of the cell surface.

Mayorella is a genus of small amoeboid protists in the phylum Amoebozoa. The genus consists of amoebae that exhibit pseudopodia and feed on a variety of organisms through phagocytosis, making them an important group in microbial ecology across most environments worldwide. Mayorella species have been found in soil, freshwater and marine environments.[2]

Etymology

Mayorella was named in the honor of Alfred G. Mayor, curator of natural sciences of the Brooklyn Institute of Arts and Sciences, the founder and first director of the Tortugas Marine Laboratory where the author of the genus, Asa Arthur Schaeffer [de], was working at the time of the genus' description in 1926.[3]

Characteristics and ecology

Mayorella amoebae use protoplasmic streaming for their movement and feeding. Like many other amoebae, they feed on bacteria, fungi and algae through phagocytosis. Their feeding promotes nutrient regeneration for the habitats, and regulates the populations of algae and bacteria. For this reason they are an important functional group in the ecology of worldwide microbial communities, for which they gain increasing recognition.[2]

Most species of Mayorella have been isolated from soil or freshwater environments, while a few have been reported from marine habitats, two of them from deep-sea areas.[2]

Classification

Taxonomic history

In 1926 the zoologist Asa Arthur Schaeffer [de] established the order Mayorella in the monotypic family Mayorellidae.[1] The taxonomic history of the genus was complex. Many amoebae had similar morphology to Mayorella had either a thick, multi-layered cell coat (or cuticle), or scales on the surface of the cell membrane. The zoologist Frederick C. Page created the genus Hollandella to gather all Mayorella-like species with cuticle, but the type species of this genus had scales instead of a cuticle, so the genus was abandoned. The species with scales were instead placed under the genus Dactylamoeba, which was later formally replaced with the name Korotnevella.[3]

The diversity of Mayorella-like amoebae is high, but the distinction between species of the genus is difficult and requires electron microscopy of the cell surface. Many species that were described by light microscopy are hardly recognizable and do not have reliable available descriptions.[3]

In 2004 it was placed in the order Dermamoebida, whose members are naked amoebae with a thick glycocalyx.[4]
