Publication: Retinal anatomy and fish vision
Environment and lifestyle exert selective pressure on, and shape the evolution of, visual systems. Eye anatomy thus often reveals specialisations to ecological niches and light environments. Roland Fritsch et al. (Front. Neuro-anatomy) analysed retinal anatomy of the benthic Mediterranean fish Tripterygion delaisi using retinal wholemounts and histology. The spatial distri-bution, patterns, and density of photoreceptors and retinal ganglion cells revealed a pronounced fovea and other adaptations to a micro-predatory and cryptobenthic lifestyle.

|02 Jun 2017||Hand entheses patterns archive human occupation|
|Reconstructing human lifestyle remains a prime challenge in archeology. New work by Alexandros Karakostis et al. (Am. J. Physic. Anthropol.) now validated a technique to infer prime occupational activity from hand entheses patterns. Individuals involved in intense manual labor during their lifetime presented a distinctive pattern of hand entheses, consistent with the application of high grip force. By contrast, individuals with less strenuous and/or highly mechanized occupations showed an entheseal pattern related to the thumb intrinsic muscles.|
|30 May 2017||Egyptian mummy genomes suggest increased Sub-Saharan ancestry in post-Roman periods|
|An international team of scientists including EVEREST student Alexander Peltzer successfully recovered and analyzed ancient DNA from Egyptian mummies dating from ~ 1400 BCE to 400 CE, establishing ancient Egyptian mummies as a reliable source for genetic material. The study (Nature Commun.) found that modern Egyptians share more ancestry with Sub-Saharan Africans than ancient Egyptians did. In contrast, ancient Egyptians were most closely related to ancient people from the Near East.|
|28 April 2017||First evidence for adaptive function of red fluorescence in fish|
|Many marine fish show striking red fluorescence, but whether these patterns are adaptive remains elusive. In new work by Ulrike Harant et al. (BMC Ecology), red fluorescent fish were more successful in catching copepods under red fluorescence-friendly ambient light spectra compared to broad-white illumination. This suggests that active photolocation might indeed be present in the tested species, and that red fluorescent colours provide and adaptive benefit in "red-deprived" marine environments.|
|07 April 2017||Andrea Schuster has graduated|
EVEREST PhD student Andrea Schuster has successfully defended her disseration entitled "Individual differences in behaviour and cognition of Eurasian Harvest Mice".
Congratulations from the whole EVEREST team!
|27 March 2017||A behavioral syndrome linking personality with cognition|
|Many animals exhibit correlated personality traits, then forming so-called behavioral syncromes. Andrea C. Schuster et al. (Front. Ecol.) now characterise a behavioural syndrome in Eurasian Harvest Mice. They found correlations between personality and spatial cognitive traits where fast behavioural types learned a spatial orientation task faster than slow types, and shyer harvest mice made decisions quicker than bolder mice. These data are among the first to provide insights into the relationship between personality and spatial cognition in animals.|
|09 March 2017||A novel form of eyeshine in marine fish|
|Eyeshine is the phenomenon of (seemingly) glowing eyes, e.g. cat eyes at night. Roland Fritsch et al. (Front. Zool.) describe a previously unknown form of eyeshine in the Mediterranean triplefin T. delaisi that is based on transmission of light through the head and optic nerve, thus termed optic-nerve-transmitted (ONT) eyeshine. Factors increasing ONT eyeshine intensity include locally reduced head pigmentation, a thin skull, and the potential light-guiding properties of the optic nerve. The authors suggest that ONT eyeshine is widespread among small fish species, and discuss how ONT eyeshine might affect visual performance and if it could serve a function.|
|03 March 2017||Animal personality in behaviour, but not cognition?|
|New work by Andrea C. Schuster et al. (Sci. Nat. / Naturwissenschaften) shows that Eurasian harvest mice behave consistently both within and between life-history stages, meeting two prerequisites to qualify animal personality. Personality traits (exploration, activity and boldness) were repeatable in juveniles and adults, and consistent before and after maturation, as well as before and after first sexual contact. In contrast, spatial recognition measured in a Y-Maze was only repeatable in adult mice and provided little evidence for consistency. This is among the first studies to investigate animal personality in a cognitive trait, and calls for further research on cognitive repeatability.|

|16 Dec 2016||Modern Syphilis infections traced back to their common ancestors|
|Syphilis is widely recognized as a re-emerging disease spreading the globe. Its causative agent, Treponema pallidum, is non-cultivable, restricting research on its origin. Researchers from Zurich and Tuebingen Universities, among them EVEREST student Alexander Peltzer, applied ancient genomics to tackle create a first phylogenetic tree to infer evolutionary history of current Syphilis strains from 13 countries around the globe (Nature Microbiology). The study suggests that current Syphilis strains share a common ancestor between 1611 and 1859.|
|16 Nov 2016||Best practice in measuring sexual selection|
|Sexual selection is a key area of behavioural and evolutionary research. Most studies rely on summarizing metrics that quantify sexual selection, such as the Bateman gradient. EVEREST alumni Ines Häderer et al. (Methods Ecol. Evol.) scrutinize the methodology underlying these metrics, raise attention to systematic biases due to study design, and derive best-practice guidelines for future work.|
|15 Nov 2016||Phylogenetic patterns of fluorescence in fish|
|Red fluorescent pigments are widespread among benthic marine fish, but their adaptive function remains elusive. EVEREST alumni Tobias Gerlach and coworkers (Front. Ecol. Evol.) desribe the diversity of fluorescent patterns across marine fishes, and test whether their phylogenetic distribution is consistent with proposed adaptive functions. The data support the idea that fluorescence is involved in camouflage, active photolocation, and sexual signalling.|
|03 Nov 2016||New publication|
A new study by Julia Geue et al. (Ecology and Evolution) indicates that environmental selection is a main driver of population divergence in house sparrows (Passer domesticus) in Romania and Bulgaria. This adds further evidence to the idea that adaptive evolution may be a major driver of population divergence.
|27 Oct 2016||Meeting StEvE on Nov 4|

|05 Oct 2016||New publication|
New work by Peter Pogoda et al. (Amphibia-Reptilia) enhances our understanding of sexual dimorphism in caecilians, snake-like amphibians with almost inexistent sexual differentiation. The new study reveals sex-differences in cloacal disc size and tail width, and describes unexpected cryptic, ontogeny-related variation in nuchal collars.
26 Sep 2016: New publication
Eleanor Gibson-Forty co-authors a study (Frontiers in Plant Science) that introduces a unique global change field experiment. Using rainout shelters, it simulates predicted changes in rainfall to understand how grassland ecosystems respond to climate change.
26 Sep 2016: Retreat
Some of our students just returned from a very successful PhD retreat to Blaubeuren. Watch out for a full update on our 'Information for Students, PhD retreat' page, soon.
23 Sep 2016: New publication
Martin Vallon et al. (Ecology and Evolution) study the evolutionary conundrum that brood-caring male fish routinely eat their own young. Egg cannibalism specifically targeted mould-infected eggs, while males could not distinguish eggs sired by themselves vs. sneaker-males.
21 Sep 2016: New publication
New work by Alexander Immel et al. (Scientific Reports) is the first to document how X-ray irradiation detrimentally affects the quantity and quality of DNA extracted from archeological finds. The study shows how to subject bones to computer tomography without affecting their aDNA.
