Diversification dynamics of the Arabian squamate reptiles spatial and temporal patterns and their key predictors (GJ18-15286Y)

the Arabian reptiles as a study system. Reptiles dominate arid regions and are therefore reptiles was generated. We will further identify factors that shaped the distribution of Arabian reptiles by triggering shif...

Developmental and evolutionary aspects of polyphyodont and heterodont dentition in reptiles (KJB601110910)

Reptiles are characterized by polyphyodont homodont dentition mostly with unicuspid or bicuspid teeth. The heterodont dentition appears in several reptilian, the molecular mechanisms of polyphyodont and heterodont teeth development in re...

Evolution of sex determining systems in squamate reptiles molecular cytogenetic test of multiple independent origins of sex chromosomes (GAP506/10/0718)

Sex determination in reptiles occurs in basically two different modes: the sex is determined eitherby sex chromosomes (genotypic sex determination, GSD), or by environmental factors(environmental sex determination, ESD). In squamate rept...

Evolution of sex chromosomes in toxicoferan reptiles (GJ17-22141Y)

their sex is determined. Among vertebrates, reptiles demonstrate a vast variability in Toxicofera, one of the most species-rich groups of reptiles. Our aim is to expand our hypotheses about transitions of sex determination systems ...

How does the genome feel the heat? Effect of incubation temperatures on gene expression, transposon activity and recombination in squamate reptiles. (GA25-16674S)

The oviparous reptiles are especially vulnerable to ambient temperature during the egg incubation period because of their high physiological response to thermal conditions and the absence of parental care in most species. Previous studies do...

Environmental sex determination in amniote vertebrates a stress‐related mechanism? (GA23-07658S)

Several reptile lineages possess environmental sex determination (ESD) where the sex of an individual is determined by non-genetic processes. Many aspects of ESD temperatures might represent in fact a stressor and that reptile ESD c...

Evolutionary diversity of desert reptiles across phylogenetic and spatial scales hotspots, refugia, and their conservation (GA25-17736S)

Extreme deserts are among the harshest environments to live in. Yet, they support a unique biota perfectly adapted to the torrid conditions and shaped by particular ecological processes. Squamates dominate deserts and are thus a good model for studyi...
