… In this respect it is interesting that in the second deepest lake in Nicaragua, Crater Lake
Xiloá (maximum estimated depth, 100 m), an elongated morphotype of the Midas cichlid occurs …

The recurrent evolution of convergent forms is a widespread phenomenon in adaptive
radiations (eg, [1–9]). For example, similar ecotypes of anoles lizards have evolved on different …

… , laboratory grown, with intact bodies and intact or slightly damaged shells (in case the snail
was deemed too large), (2) snail bodies, where the shells were manually removed, and (3) M…

… Lake Victoria is located in East Africa at an altitude of 1135 m above sea level (m asl). Overall,
… in the highlands at 1950 m asl, it ranges around 14.3 C and at 3250 m asl around 7.1 C. …

… Specifically, there are some 50 N e m (number of effective migrants per generation) in
populations found in the same locality and ~5–10 N e m in populations separated by 1–10 km 13,…

The field of paleolimnology has made tremendous progress in reconstructing past biotic and
abiotic environmental conditions of aquatic ecosystems based on sediment records. This, …

The evolution of convergent phenotypes is one of the most interesting outcomes of replicate
adaptive radiations. Remarkable cases of convergence involve the thick‐lipped phenotype …

… The deepest point of the lake is 68 m and our deepest core LV4 is at 63 m. Our deepest …
6 m water depth); sublittoral (6–20 m water depth); and deep waters (greater than 20 m water …

The interplay between selection and aspects of the genetic architecture of traits (such as
linkage, dominance, and epistasis) can either drive or constrain speciation [1–3]. Despite …

The types of mutations affecting adaptation in the wild are only beginning to be understood.
In particular, whether structural changes shape adaptation by suppressing recombination or …
