“…In the lakes of Montebello, Chiapas, the families Chironomidae, Hyalellidae, Coenagrionidae and Scirtidae are recorded as the most dominant (Guadarrama-Hernández et al, 2015;Orozco-Martínez, 2016). The high mountain lakes, El Sol and La Luna del Nevado de Toluca (Oseguera et al, 2016), recognize only eight species of macroinvertebrates, mainly oligochaetes, chironomids and bivalves standing out for their abundance.…”

Studies related to macroinvertebrates that have been carried out within the Lagunas de Zempoala National Park (PNLZ), Morelos, Mexico, have focused mainly on three of the four lakes that still have water resources available. With this, it can be considered that the information on the macroinvertebrate communities in this area continues to be relatively unknown. The present work is aimed at recording the biodiversity of macroinvertebrates that inhabit the coastal zone of Lake Acoyotongo of the PNLZ. Four collection campaigns were carried out, considering the rainy and dry seasons. A total of 7,822 organisms were obtained, distributed in three phyla, six taxonomic classes: Arachnida, Clitellata, Entognatha, Gastropoda, Insecta and Malacostraca; 14 orders and 26 families. The Insecta class presented six orders obtaining the greatest richness of species: Hemiptera with five families; Coleoptera, Diptera and Odonata with three families each; Ephemeroptera and Lepidoptera with one family each. The study defined the ecological state of the lake, since its members reflect how the community relates in the sense of the functionality of the system.

“…For zooplankton biomass, we took the reported average biomass [ 35 ] and multiplied it by the zooplankton carbon percentage measured in this study. For benthic organisms, we used the reported biomass directly [ 47 ], except for gastropods, because this is the first study that sampled and reported gastropods ( Physa sp.) in El Sol; for those, we used an average biomass value to calculate a neutral hyperparameter α and to avoid further bias in their contribution to the rainbow trout diet.…”

Food web differences between two neighboring tropical high mountain lakes and the influence of introducing a new top predator

High mountain lakes (HMLs) are considered unique and comparable ecosystems for monitoring global climate change. The food web structure can indicate the response of these ecosystems to ecological threats, such as fish introduction, by analyzing the trophic dynamics. Nonetheless, the food webs of tropical HMLs are less well-studied than temperate HMLs. The present study assessed the food webs of two neighboring (600 m apart) tropical HMLs, El Sol and La Luna, inside the crater of the Nevado de Toluca volcano, Mexico. It used stable isotopes (δ13C and δ15N) and Bayesian mixing models with different trophic discrimination factors and priors to assess the impacts of introduced rainbow trout, persisting only in the larger lake, El Sol. The food web in Lake El Sol was more complex than in Lake La Luna, mainly due to its larger size, extensive vegetated littoral zone, and being fueled by autochthonous primary production. In contrast, the smaller and fishless Lake La Luna has a reduced and bare littoral zone that harbored a simple food web substantially sustained by allochthonous carbon inputs. The persistence of introduced rainbow trout in Lake El Sol but not in Lake La Luna accentuated the differences between the lakes. The models suggested that rainbow trout fed on key consumers of littoral macroinvertebrates (70–80%) and pelagic zooplankton (20–30%), increasing the linkage between sub-networks. In both tropical HMLs, the species richness and herbivorous fraction were elevated compared with temperate HMLs, while the linkage density and omnivorous fraction were lower. Basal nodes dominated these tropical HMLs, and the vegetated littoral zone of Lake El Sol had more intermediate (omnivore) nodes. Our results showed the convenience of food web analysis to compare the effects of introduced fish in originally fishless lakes in different latitudes.
