Currently, freshwater zooplankton sampling and identification methodologies have remained virtually unchanged since they were first established in the beginning of the XX century. One major contributing factor to this slow progress is the limited success of modern genetic methodologies, such as DNA barcoding, in several of the main groups. This study demonstrates improved protocols which enable the rapid assessment of most animal taxa inhabiting any freshwater system by combining the use of light traps, careful fixation at low temperatures using ethanol, and zooplankton‐specific primers. We DNA‐barcoded 2,136 specimens from a diverse array of taxonomic assemblages (rotifers, mollusks, mites, crustaceans, insects, and fishes) from several Canadian and Mexican lakes with an average sequence success rate of 85.3%. In total, 325 Barcode Index Numbers (BINs) were detected with only three BINs (two cladocerans and one copepod) shared between Canada and Mexico, suggesting a much narrower distribution range of freshwater zooplankton than previously thought. This study is the first to broadly explore the metazoan biodiversity of freshwater systems with DNA barcodes to construct a reference library that represents the first step for future programs which aim to monitor ecosystem health, track invasive species, or improve knowledge of the ecology and distribution of freshwater zooplankton.

“…Both genetic analyses and morphology, have been employed to successfully discriminate sibling species of marine and freshwater copepods [24], [25], cladocerans [23], rotifers [26], polychaetes [27], and others. These descriptions based on morphology and molecular data, are part of the integrative taxonomy [28], a new approach where different types of evidence converge to support the species discovery that currently is revitalizing this discipline [29].…”

An Example of How Barcodes Can Clarify Cryptic Species: The Case of the Calanoid Copepod Mastigodiaptomus albuquerquensis (Herrick)

2014

BackgroundThe freshwater calanoid Mastigodiaptomus is a genus with high richness in the Americas and is composed of nine species, seven recorded in Mexico and four that are apparently endemic to small areas. Mastigodiaptomus albuquerquensis is a common, widely distributed species ranging from the southern USA to Central America. This species can be easily identified by a notable butterfly-like sclerotization on the basis of the right fifth leg of males. Nevertheless, morphological differences observed among populations throughout this species distributional range have led to the description of several related species or subspecies, such as M. albuquerquensis patzcuarensis from Lake Pátzcuaro in the Central Plateau of Mexico.MethodsGenetic results based on barcodes, morphology based on scanning electron and light microscopy images, and morphometric analyses were used to describe cryptic species within the M. albuquerquensis complex.ResultsThe morphological analyses coincided partially with the genetic markers, suggesting the existence of at least two sibling species: M. albuquerquensis s. str. and M. patzcuarensis. A third species was genetically separated but was morphologically indistinguishable from the M. patzcuarensis group.ConclusionsHidden diversity has been a major problem in establishing real patterns of species distribution and genetic acquisition from megadiverse hotspots such as Mexico, where the Nearctic and the Neotropical regions of the Americas meet. Barcodes can help taxonomists to reveal and formally name these new species. Here, we describe two of three potential species highlighted by the use of barcodes: M. albuquerquensis s. str. in the northern semi-desert and M. patzcuarensis on the Central Plateau at more than 2000 m above sea level.

“…Identification of the animals was based on the keys of Kutikova () Koste (, ), Einsle (), Nogrady et al (), Nogrady and Segers (), Segers (, ), De Smet (, ), Gulyás and Forró (, ), and Flössner (). Members of the Acanthocyclops robustus species complex were identified according to Mirabdullayev and Defaye (, ) and Miracle et al (). In the case of bdelloid rotifers, identification is impossible from preserved samples, hence we used the category “bdelloids” in the species list.…”

Despite the high conservation value of intermittent soda pans, these habitats were mostly targeted by small‐scale studies and little is known about their microscopic fauna. We sampled all the remaining 110 representatives of this habitat type (including recently restored ones) in Europe in an area covering approximately 125 000 km2. We analyzed spring and summer zooplankton species composition including rotifers, copepods, and cladocerans. We found 105 Rotifera, 26 Cladocera, and 26 Copepoda taxa, with local species richness ranging between 1 and 38 taxa. Alpha diversity was comparable in the two main groups (Rotifera, Crustacea), while beta and gamma diversity was higher in rotifers. The most frequently occurring zooplankters were crustaceans, while rotifer taxa were rarer as the most frequent species inhabited less than half of the pans. Dominance of the natronophilic Arctodiaptomus spinosus proved to be a reliable indicator for high quality soda pans. We concluded that the most typical soda pan zooplankton communities developed by early summer, in the concentrated pans, thus we would suggest considering this period as a reference for ecological state monitoring, and especially for evaluating the success of soda pan rehabilitations or reconstructions with the help of zooplankton. Based on these criteria, restorations could be considered only moderately successful.
