“…Wetlands, water corridors, natural lakes and a pond are part of the remnants of the Xochimilco and Chalco extinct saline lakes (located in the southwestern part of the urban area of the city). These water bodies have alkaline pH and a high content of organic matter [45,46]. Interestingly, regardless of its size and freshwater capacity (470, 625 m 3 ; [47]), canoe canals harbored only three species: Cx .…”

Since past century, vector-borne diseases have been a major public health concern in several states of Mexico. However, Mexico City continues to be free of endemic mosquito-borne viral diseases. The city is the most important politic and economic state of Mexico and one of the most important city of Latin America. Its subtropical highland climate and high elevation (2240 masl) had historically made the occurrence of Aedes species unlikely. However, the presence of other potential disease vectors ( Culex spp, Culiseta spp), and the current intermittent introductions of Aedes aegypti , have revealed that control programs must adopt routine vector surveillance in the city. In this study, we provide an updated species list from a five-years of vector surveillance performed in Mexico City. A total of 18,553 mosquito larvae were collected. Twenty-two species from genus Culex , Aedes , Culiseta , Anopheles , Lutzia and Uranotaenia were observed. Nine new mosquito records for the city were found. Ae . albopictus was recorded for the first time in Mexico City. Interestingly, a new record, Ae . epactius was the most frequent species reported. C x . pipiens quinquefasciatus exhibited the highest number of individuals collected. We detected six areas which harbor the highest mosquito species records in the city. Cemeteries included 68.9% of our collection sites. Temporarily ponds showed the highest species diversity. We detected an increasing presence of Ae . aegypti , which was detected for three consecutive years (2015–2017), predominantly in the warmer microclimates of the city. We found a possible correlation between increasing temperature and Ae . aegypti and Ae . albopictus expanding range. This study provides a starting point for developing strategies related to environmental management for mosquito control. The promotion of mosquito control practices through community participation, mass media and education programmes in schools should be introduced in the city.

“…For example, most works have shown the dominance of Brachionidae (e.g., Keratella, Anuraeopsis) and Polyarthra (Jiménez-Contreras et al, 2009;FigueroaSanchez et al, 2014) in drinking water reservoirs, while in recreational waterbodies such as Llano Reservior, Trichocerca and bdelloids often dominate (Muñoz-Colmenares et al, 2017). On the other hand, in shallow waterbodies such as Lake Xochimilco, species of Brachionus (B. calyciflorus, B. havanaensis, B. angularis and B. caudatus), Keratella (K. cochlearis, K. tropica) and Lecane (L. bulla) are dominant (Nandini et al, 2016;Gayosso-Morales et al, 2017). In deep lakes such as El Sol and La Luna the dominant rotifers are Polyarthra dolichoptera and Conochilus unicornis, bdelloids, Lecane lunaris and Lepadella accuminata (Dimas-Flores et al, 2008).…”

To understand the population growth potential of different species of rotifers in nature, field collections through seasons are essential. We sampled zooplankton (and measured selected physicochemical variables) from the Madín reservoir, a high altitude eutrophic urban waterbody from Mexico, every month for a year. Qualitative analysis of zooplankton revealed 28 rotifer species and four cladoceran crustaceans plus one unidentified copepod. Cephalodella catellina (1400 ind L -1 ), Horaella thomassoni (550 ind L -1 ), Conochilus dossuarius (380 ind L -1 ) and Filinia longiseta (25 ind L -1 ) had higher peak density than other rotifers. Based on the concentrations of nitrates and phosphates, chlorophyll a levels or different diversity indices (e.g., Carlson, Shannon-Wiener, Pantle and Buck, Ejsmont-Karabin's TSI Rot ), the waterbody is eutrophic to hypertrophic, depending on the season. In this waterbody we observed high densities of Aphanothece sp. which is a toxic picocyanobacterium. During the blooms of Aphanothece, we also recorded higher densities of H. thomassoni and C. catellina. Based on the gut contents we found that both these rotifer species feed on Aphanothece in this waterbody. This study thus suggests the potential growth of Horaella, Cephalodella, Conochilus and Filinia in this eutrophic reservoir containing blooms of Aphanothece.

“…The conditions present in our study area are probably not due to the high nutrient values (Table ), because no algal blooms occurred during the study and chlorophyll a levels rarely reach maximum values of 600 µg/ml (present study; Enríquez‐García et al, ; Nandini et al, ). However, in a nearby area, which is popular as a canoeing venue, algal blooms are common; there chlorophyll a reaches levels >1,200 µg/ml (Gayosso‐Morales, Nandini, Martínez‐Jeronimo, & Sarma, ).…”

To better understand the sessile rotifer community of a shallow, eutrophic lake, we monitored over a 1‐year period the monthly changes in the density and diversity of rotifers on the roots of the common water hyacinth, Eichhornia crassipes, which served as a representative hydrophyte. Selected physical and chemical parameters of the water were also determined. Mean annual density of all sessile species was 630 individuals per ml. Species of Collothecacea (n = 7) were most abundant. Of the 12 species of Flosculariaceae (Flosculariidae), Sinantherina socialis occurred seasonally, while Ptygura beauchampi was most common across all seasons. The Shannon–Wiener diversity index was highest (H′ = 2.8) in April, but decreased in January (H′ = 1.3). Applying the concept of the guild ratio (functional‐based analysis) we found that raptorial species (Collothecacea) were dominant over most of the year (June–February), while microphagous Flosculariidae were dominant during the warm, drier season (March–May). BEST (optimal matching of biota to environment, including stepwise search) analysis and canonical correspondence revealed that temperature, dissolved oxygen, pH, turbidity, and transparency strongly influenced sessile rotifer dynamics. We also found significant correlations between the density of some species and physicochemical variables. These species included Collotheca ambigua, C. coronetta, C. ornata, C. campanulata, C. tenuilobata, and Stephanoceros millsii in the Collothecacea; and Beauchampia crucigere, Limnias melicerta, L. ceratophylli, Ptygura crystallina, P. melicerta, and Sinantherina ariprepes in the Flosculariidae. Our study shows that the communities of sessile rotifers were structured by abiotic factors and that the guild ratio is useful for understanding the relationship between sessile rotifers and their substrata.
