Evolution &Development, EarlyView.By performing a genetic association study in cave × surface fish F2 hybrids, we discovered that premaxilla width, dentary length, and maxillary length are all significantly associated with a region on Chromosome 13 containing 109 genes. ABSTRACT The regulation of bone size is a poorly understood and complex developmental process.

Tit for Tat in the Dear Enemy Relationship Between Territorial Females of a Cichlid Fish
Frontiers in Ecology and Evolution, 2018 Many territorial animals reduce aggression toward their neighbors once territorial boundaries are established. This relationship is called the dear enemy phenomenon, hypothetically based on a conditional strategy like tit for tat (TFT).

Serial monogamy benefits both sexes in the biparental convict cichlid [PDF]
PeerJ, 2019 Monogamy can be either long-term or serial, with new pairs formed with each breeding bout. Costs and benefits are associated with each strategy. Because biparental convict cichlids (Amatitlania nigrofasciata) typically switch mates, exhibiting serial ...

Changes in feeding biology of Nile tilapia, Oreochromis niloticus (L.), after invasion of water hyacinth, Eichhornia crassipes (Mart.) Solms, in Lake Victoria, Kenya [PDF]
, 1999 Oreochrimis niloticus (L.) was introduced to Lake victoria in the 1950s. It remained relatively uncommon in catches until 1965, when the numbers began to increase dramatically.

The invasion of an introduced predator, Nile perch (Lates niloticus, L.) in Lake Victoria (East Africa): chronology and causes [PDF]
Nile perch, a large predatory fish, was introduced into Lake Victoria in 1954. The upsurge of Nile perch in Lake Victoria was first observed in the Nyanza Gulf, Kenya, in 1979.

Computer Simulations to Study Sympatric Speciation Processes [PDF]
arXiv, 2005 We perform simulations based on the Penna model for biological ageing, now with the purpose of studying sympatric speciation, that is, the division of a single species into two or more populations, reproductively isolated, but without any physical barrier separating them.

Field Guide to Nonindigenous Marine Fishes of Florida [PDF]
, 2009 The purpose of this field guide is to provide information on nonindigenous (i.e., non-native) fishes that have been observed in Florida’s marine waters. Introductions of non-native marine fishes into Florida’s waters could be intentional or unintentional,

BMC Biology, 2014 BackgroundLake Tanganyika, an ancient lake in the Great Rift Valley, is famous for the adaptive radiation of cichlids. Five tribes of the Cichlidae family have acquired herbivory, with five ecomorphs: grazers, browsers, scrapers, biters and scoopers ...

Climate‐Mediated Hybridisation and the Future of Andean Forests
Journal of Biogeography, EarlyView.ABSTRACT The tropical Andes face unprecedented warming and shifting precipitation patterns due to climate change and land‐use alteration, challenging the future of Andean forests. During the Quaternary, many Andean trees responded to climate change through upslope migrations but, while there is evidence of such ongoing migrations in many species, they ...
