“…Owing to the difficulty to clearly identify species in sub-adult or non-breeding life stages underwater and the ongoing debate and steady changes in species classification, the overall number of Amphilophus spp. individuals was counted and no attempts were made to distinguish species, hybrids, or morphotypes (e.g., Barlow, 1976;McKaye et al, 2002;Bunje et al, 2007;Stauffer et al, 2008). In this visual survey a minimal bias among and within observers is expected due to individual survey differences (Thompson & Mapstone, 1997).…”

“…Furthermore, they differ in the number of cichlid species. Crater Lake Apoyo is suggested to harbor six endemic species of the Amphilophus complex (Barlow, 1976;Stauffer et al, 2008;Geiger et al, 2010b) (Supplementary Table 1), which most likely go back to a seeding lineage from adjacent Lake Nicaragua (Barluenga et al, 2006); together with Parachromis managuense and the recently introduced African species Oreochromis aureus and O. niloticus, these are the only cichlids found in this lake. In Lake Xiloá three to four endemic species of the Amphilophus species complex are described (Supplementary Table 1), which derive from the close-by Lake Managua stocks (Barluenga & Meyer, 2010).…”

Depth-dependent abundance of Midas Cichlid fish (Amphilophus spp.) in two Nicaraguan crater lakes

et al. 2012

The Midas Cichlid species complex (Amphilophus spp.) in Central America serves as a prominent model system to study sympatric speciation and parallel adaptive radiation, since small arrays of equivalent ecotype morphs have evolved independently in different crater lakes. While the taxonomy and evolutionary history of the different species are well resolved, little is known about basic ecological parameters of Midas Cichlid assemblages. Here, we use a line transect survey to investigate the depth-dependent abundance of Amphilophus spp. along the shores of two Nicaraguan crater lakes, Apoyo and Xiloá. We find a considerable higher density of Midas cichlids in Lake Xiloá as compared to Lake Apoyo, especially at the shallowest depth level. This might be due to the higher eutrophication level of Lake Xiloá and associated differences in food availability, and/or the presence of a greater diversity of niches in that lake. In any case, convergent forms evolved despite noticeable differences in size, age, eutrophication level, and carrying capacity. Further, our data provide abundance and density estimates for Midas Cichlid fish, which serve as baseline for future surveys of these ecosystems and are also relevant to past and future modeling of ecological speciation.

“…Fish heads or whole fish were taken as vouchers and stored in 70% ethanol. Species were initially taxonomically classified on site based on diagnostic keys and species descriptions [18][19][20]32,33 and later confirmed independently from photographs. Species were assigned to limnetic or benthic ecomorphs based on species descriptions and previous publications 16,[18][19][20]34 and confirmed by a canonical variates analysis (see 'Body shape and size' under the methods section) that separated A. zaliosus in Apoyo and A. sagittae in Xiloá from all sympatric species (hereafter Limnetics ¼ A. zaliosus and A. sagittae; Benthics ¼ all other species; Supplementary Fig.…”

Parallel evolution of Nicaraguan crater lake cichlid fishes via non-parallel routes

et al. 2014

Fundamental to understanding how biodiversity arises and adapts is whether evolution is predictable in the face of stochastic genetic and demographic factors. Here we show rapid parallel evolution across two closely related but geographically isolated radiations of Nicaraguan crater lake cichlid fishes. We find significant morphological, ecological and genetic differentiation between ecomorphs in sympatry, reflected primarily in elongated versus high-bodied shape, differential ecological niche use and genetic differentiation. These eco-morphological divergences are significantly parallel across radiations. Based on 442,644 genome-wide single nucleotide polymorphisms, we identify strong support for the monophyly of, and subsequent sympatric divergence within, each radiation. However, the order of speciation differs across radiations; in one lake the limnetic ecomorph diverged first while in the other a benthic ecomorph. Overall our results demonstrate that complex parallel phenotypes can evolve very rapidly and repeatedly in similar environments, probably due to natural selection, yet this evolution can proceed along different evolutionary genetic routes.

“…(d) Midas cichlid diversity and the question of species An overall assessment of the Midas cichlid species complex was due, given that in recent years six new species have been described (Stauffer & McKaye 2002;Stauffer et al 2008). Prior to those species descriptions, Klingenberg et al (2003) analysed body shape differences among the species that were at that time properly taxonomically described:…”

The polychromatic and trophically polymorphic Midas cichlid fish species complex (Amphilophus cf. citrinellus) is an excellent model system for studying the mechanisms of speciation and patterns of phenotypic diversification in allopatry and in sympatry. Here, we first review research to date on the species complex and the geological history of its habitat. We analyse body shape variation from all currently described species in the complex, sampled from six crater lakes (maximally 1.2 -23.9 kyr old) and both great lakes in Nicaragua. We find that Midas cichlid populations in each lake have their own characteristic body shape. In lakes with multiple sympatric species of Midas cichlid, each species has a distinct body shape. Across the species complex, most body shape change relates to body depth, head, snout and mouth shape and caudal peduncle length. There is independent parallel evolution of an elongate limnetic species in at least two crater lakes. Mitochondrial genetic diversity is higher in crater lakes with multiple species. Midas cichlid species richness increases with the size and age of the crater lakes, though no such relationship exists for the other syntopic fishes. We suggest that crater lake Midas cichlids follow the predicted pattern of an adaptive radiation, with early divergence of each crater lake colonization, followed by intralacustrine diversification and speciation by ecological adaptation and sexual selection.
