“…Overall, we found a total number of 39 monogonont rotifer species belonging to 20 genera. Although our study detected a lower number of rotifer species compared to other large-scale studies conducted in Italy, Russia, Poland, Mexico and USA (Braioni & Gelmini, 1983; Kutikova, 1998; Ejsmont-Karabin et al, 2004; Sarma et al, 2021; Brown et al, 2020), our findings suggest that a single sampling of spatio-temporal reservoirs of resting eggs can detect a sufficiently high number of species for diversity assessment and related community/metacommunity analysis. Most importantly, many of the species we detected (25) have not been previously reported from the region, substantially adding to the rotifer diversity in Israel.…”

“…Epiphanes brachionus, a recognized indicator species for North America playa habitats (i.e., temporary and semi-permanent water bodies of various sizes; Sublette & Sublette, 1967;Brown et al, 2020), which are comparable in their environmental characteristics (i.e., hydroperiod) to our study system, was found to be extensively distributed in the Mediterranean coast and mountain regions.…”

Temporary ponds represent ecologically important habitats that support high species diversity and provide essential ecosystem services, particularly in certain countries surrounding the Mediterranean Sea, where natural lakes are scarce. Israel is located along the southeastern Mediterranean coast and features Mediterranean and arid climatic zones that vary in a variety of meteorological parameters. Temporary ponds are prevalent throughout Israel, including the Mediterranean coast, Mediterranean mountain (i.e., Galilee region), and arid climatic zones. These temporal ponds harbor diverse invertebrate communities that exhibit significant spatial and temporal variations. Among these communities, Monogonont rotifers are notably one of the most diverse and abundant groups. Despite their significant role in aquatic food webs, rotifers are often overlooked in environmental studies, likely due to their small size and difficulties associated with their taxonomy. Resilient resting eggs produced by Monogonont rotifers during periods of unsuitable environmental conditions serve as significant source of propagules that drive the recolonization of temporary ponds upon rehydration, thereby influencing the dynamics of the pond community and metacommunity organization. Here, we examined the diversity of Monogonont rotifers by rehydrating sediment from 30 temporary ponds across Israel. Our analysis identified 39 species, with 25 (64%) of them being reported for the first time in Israel. We found the highest diversity of Monogonont rotifers in the Mediterranean coast region, which is characterized by low altitude, long hydroperiod, and relatively low mean summer daily maximum temperature, while the lowest diversity was found in the Arid region which is characterized by high altitude, short hydroperiod, and high mean summer daily maximum temperature. Our findings suggest that altitude, hydroperiod and mean summer daily maximum temperature are important parameters associated with the observed biodiversity patterns. Our metacommunity analysis further revealed a small contribution of geographic distance (2%) and environmental factors (1%) in shaping rotifer metacommunities. We also found a significant positive correlation among community composition, environmental distance (i.e., Gower’s distance) and geographic distance, possibly due to a linearity in the sampling set-up. Overall, our study highlights the importance of temporary ponds as significant habitats for diverse rotifer communities and emphasizes the need to further study “micro” invertebrate diversity in these unique ecosystems.

“…Second, even though the regional species accumulation curve suggests that the regional species richness value ( 21) is close to the actual species richness present in the lakes of the PNLM, two methodological concerns must be mentioned. a) Most rotifer studies use nets with smaller mesh size (35-µm or 25-µm, References [56][57][58]) than our (54-µm). b) Rotifer biodiversity studies usually report species from both the littoral and the pelagic zones (e.g., References [7][8][9]12]), while ours included just the pelagic zone.…”

Regional Pelagic Rotifer Biodiversity in a Tropical Karst Lake District

2020

The species richness, composition, abundance, and biomass of pelagic rotifers were determined in 17 karst lakes of the “Lagunas de Montebello” National Park, Chiapas, Mexico. The species richness of the region (21 species) and single lakes (1–12 species) was smaller than that of other Mexican, tropical, and temperate lakes. It is worth noting the high dissimilarity in species composition—about half (52%) of the species were observed in only 1–3 lakes. A total of eight rotifer families, all from the Monogononta subclass, were recorded. Keratella americana was the species with the highest occurrence (13 lakes), followed by Ptygura sp. (8 lakes). The abundance (0 to 536 ind L−1) and biomass (0 to 21 µg L−1) of rotifers were low. The highest values of species richness, abundance, and biomass were found in eutrophic lakes, and the lowest in oligotrophic lakes. The low values of rotifer biodiversity, abundance, and biomass in the Montebello lakes are probably the product of the interaction of different factors—such as environmental homogeneity (all water bodies are karst lakes), the low availability of “good-quality” food, and predation by cyclopoid copepods in the eutrophic lakes, and the low availability of food, and competitive interference by calanoid copepods and cladocerans in the oligotrophic lakes.

Rotifer Species Diversity in Mexico: An Updated Checklist

2021

View full text Add to dashboard Cite

A review of the Mexican rotifer species diversity is presented here. To date, 402 species of rotifers have been recorded from Mexico, besides a few infraspecific taxa such as subspecies and varieties. The rotifers from Mexico represent 27 families and 75 genera. Molecular analysis showed about 20 cryptic taxa from species complexes. The genera Lecane, Trichocerca, Brachionus, Lepadella, Cephalodella, Keratella, Ptygura, and Notommata accounted for more than 50% of all species recorded from the Mexican territory. The diversity of rotifers from the different states of Mexico was highly heterogeneous. Only five federal entities (the State of Mexico, Michoacán, Veracruz, Mexico City, Aguascalientes, and Quintana Roo) had more than 100 species. Extrapolation of rotifer species recorded from Mexico indicated the possible occurrence of more than 600 species in Mexican water bodies, hence more sampling effort is needed. In the current review, we also comment on the importance of seasonal sampling in enhancing the species richness and detecting exotic rotifer taxa in Mexico.
