Hyalella azteca is a widespread and abundant

waterfowl
.

Description

Hyalella azteca has body plan similar to most amphipods and is a classic freshwater example of the order. They grow to a length of 3–8 millimetres (0.12–0.31 in), with males being larger than females.[1] Their color is variable, but the most frequent hues are white, green and brown.[1]

They are identified from other similar species by antenna 1 being equal or shorter than antenna 2, 1 spine on each plate 3rd and 4th from the last on the dorsal side, Pereopod I and II are gnathopod with males having a visibly larger gnathopod.

Distribution

Hyalella azteca is found across

freshwater, including lakes and rivers,[1] extending into tidal fresh water, and freshwater barrier lagoons.[2] It is "the most abundant amphipod of lakes [in North America]",[3]
with golf course ponds sometimes supporting large populations.

Ecology

In contrast to other species of Hyalella, H. azteca is extremely common and has wide ecological tolerances.[4] It can tolerate alkaline waters and brackish waters, but cannot tolerate a pH lower (more acidic) than 6.0.[4]

The main foodstuffs of H. azteca are

leaf litter.[5] It can, however, assimilate 60%–90% of the bacterial biomass that it ingests.[5]

Hyalella azteca is an important food for many

waterfowl. In Saskatchewan, 97% of the diet of female white-winged scoters was observed to be H. azteca, and it also makes up a significant part of the diet of lesser scaup.[6]

Insecticide resistance

Some H. azteca have evolved

fitness cost under higher temperatures.[7]

Life cycle

Hyalella azteca passes through a minimum of nine instars during its development.[4] Sexes can first be distinguished at the 6th instar, with the first mating occurring in the 8th instar. Subsequent instars, of which there may be 15–20, are considered adulthood.[4]

Uses

Hyalella azteca are used in various aquatic bioassays [8] (also called toxicity tests). Because of their wide distribution, ease of captive reproduction, and its niche in lake sediments, Hyalella azteca are used in aquatic toxicology assays in sediments [9] Hyalella azteca have been used to test bioaccumulation of different contaminants such as manufactured nanomaterials [1], pesticides [2], and metals [3]. [4] [5][6]

Taxonomic history

Hyalella azteca was first described by

junior synonyms, including:[12]

  • Hyalella dentata S. I. Smith, 1874
  • Hyalella fluvialis Lockington, 1877
  • Hyalella inermis S. I. Smith, 1875
  • Hyalella knickerbockeri Bate, 1862
  • Hyalella ornata Pearse, 1911

When Sidney Irving Smith erected the genus Hyalella in 1874, H. azteca was the only included species, and therefore the type species.[13] The genus now includes dozens of species, mostly in South America.[13]

H. azteca is now thought to represent a

morphotypes are known to coexist in some areas.[10] Two local populations have been described as separate species – Hyalella texana from the Edwards Plateau of Texas, and Hyalella montezuma from Montezuma Well, Arizona.[10]
In addition to being a species complex, laboratory work sequencing and analyzing the genome of lab populations of Hyalella azteca revealed Hyalella azteca shares characteristics of other model organisms. [8]. How these crustaceans interact with contaminants can provide insight about how other species will interact with those same contaminants.

Genome Sequencing Project

There is an ongoing Hyalella azteca genome sequencing project.[14][15] [16]

This is part of a larger project being led by the Baylor college of Medicine Human Genome Sequencing Center (BCM-HGSC) ; in which 28 arthropod genomes are being sequenced.[14]

The sequencing of these genomes serves as a beginning to the larger i5k initiative, which has an end goal of sequencing 5,000 Arthropoda. Scientists looking to contribute to this research are able to nominate species to sequence, and download and share data to i5k website.[14] Data can also be submitted to the Global Genome biodiversity workshop Biodiversity Repository.[14]
