Today’s #SundayFishSketch is my nemesis, the cichlid Astatotilapia burtoni. The sex determination system in these guys is the source of at least 3 of my current headaches 😒

In crater Lake Masoko one fish species is splitting into shallow and deep-living ecotypes occupying different light environments. New research shows their visual systems are diverging, and how colours of male eggspots have changed to maximise their visibility. doi.org/10.1093/molb...
Lake Masoko in Southern Tanzania, also known as Lake Kisiba, is only ~40m deep and 600m in diameter. It was formed around 50,000 years ago, and is isolated from all nearby rivers and lakes. Genetic data suggest it was colonised by Astatotilapia calliptera around 10,000 years ago. In Lake Masoko, Astatotilapia calliptera has two ecotypes. The shallow living "littoral" ecotype has yellowish males, while the deep living "benthic" ecotype has blueish males. Recently published research led by Madeleine Carruthers and colleagues shows how these fish occupy different light regimes, and have correspondingly different visual sensitivities. Males of these ecotypes have brightly coloured eggspots, used to signal their prowess. The colours of those spots have shifted to maximise their visibility to other fish of the same ecotype. Genetic data suggest these ecotypes are largely reproductively isolated, and started to separate only 1000 years ago. Photos are kindly provided by Ad Konings.

Our new iScience study with @todthiele.bsky.social and @arrenberglab.bsky.social asks: how do larval cichlids actually perform this behavior?

los Astatotilapia burtoni realizan fecundación oral de los huevos, Rhodeus amarus introduce huevos dentro de almejas vivas para que los protejan y las Aspidoscelis neomexicanus se reproducen sin machos (no existen en la especie). Si quiere buscar cosas alienígenas que mire datos de peces.

Good morning, #SBN2026! The cichlid Astatotilapia burtoni (researchers) are taking over Niagara Falls! Three trainees from the Alward lab are presenting at today’s poster session. See flier below. Come by P9 (Lauren), P26 (Maddy), and P41 (Lexi) to see what we’ve been up to! @sbn-bsky.bsky.social

Very cool study by Sebastian Alvarado looking at how a cichlid species, Astatotilapia burtoni, raised in different gravel colors (blue versus yellow) changes the fishes color and behavior - and that’s influenced by DNA methylation #Evol2024

Our first Frank A. Beach Award winner was Dr. Beau Alward, who gave a wonderful talk on the nuances of steroid action in the brain on territoriality and mating behavior in Astatotilapia. 🐟️ Congrats to Dr. Alward for this well-deserved award!! 🎉

Smith, Musilova & @astridboehne@bsky.social find new sex chromosomes in a group of cichlids from Lake Tanganyika and show that while these involve the same chromosome pairs, the sex chromosomes evolved independently.

GBE | Same Sex Chromosomes With Independent Origins in Haplochromine Cichlids Known sex chromosomes, and sex-linked regions thereof, of African haplochromine cichlid fishes, relative to the genome of Astatotilapia calliptera (bottom-left illustration). While there is great diversity of sex chromosomes and regions of sex linkage across this clade, LG5 and LG7 frequently reappear as sex-linked, particularly within the Lake Tanganyika-specific tribe of haplochromines, the Tropheini. Sex-linked regions on LG5 and LG7 are shown, highlighted in blue for XY systems and orange for ZW systems. In species in which sex-linkage is not known, this is marked with ‘?’. Other known sex chromosomes are listed on the right. Species included in this study are marked in bold. Proposed origins of different sex determination systems or genes are shown with yellow arrows on tree branches, while losses are shown with black arrows.

They can’t take it back now 🏃🏼‍♀️ Time to finish packing to move to Michigan!
Pic of the new grad next to the Testudo turtle mascot statue in front of the library. Fun fact the OG Testudo was a female and she died a horrific death 🥲 In my natural habitat… rockin the bright red regalia in the fish room. Definitely cool brand new PhD aggressively pointing at an Astatotilapia burtoni that really would rather be fed, thanks.

I think we can say that there is a paraphyletic 'riverine' assemblage that will never join the Victorian Haplochromis clade unless that clade also includes every haplochromine endemic to Lake Malawi. I propose we call that Astatotilapia for now.
