An individual-based simulation framework exploring the ecology and mechanistic underpinnings of larval crowding in laboratory populations of Drosophila

S. Venkitachalam, A. Joshi

The paper develops an individual-based simulation framework to explore how feeding band density influences larval competition and evolutionary outcomes in Drosophila cultures.

More than just density: the role of egg number, food volume and container dimensions in mediating larval competition in Drosophila melanogaster

S. Venkitachalam, S. V.S., A. Joshi

This study shows that larval competition in Drosophila melanogaster depends on egg number, food volume, and container dimensions, not just density, and introduces effective density as a better metric.

The role of greater competitive ability in countering age disadvantages in larval competition in Drosophila melanogaster

S. Venkitachalam, A. Deep, S. Das, A. Joshi

This study shows that Drosophila melanogaster populations adapted to larval crowding better counter age disadvantages in competition than low-density controls, but differences in egg size and hatching time among these populations do not improve their performance against age-disadvantaged competitors.

The evolution of competitive effectiveness and tolerance in populations of Drosophila melanogaster adapted to chronic larval crowding at varying combinations of egg number and food volume

S. Venkitachalam, C. Temura, R. Kokile, A. Joshi

This study examines how competitive effectiveness and tolerance evolve in Drosophila melanogaster under different chronic larval crowding conditions and finds they vary with selection regime and outcome traits.

Density-dependent selection in Drosophila: evolution of egg size and hatching time

S. Venkitachalam, S. Das, A. Deep, A. Joshi

This study shows that egg size and hatching time evolve in response to different larval crowding regimes in Drosophila, with egg size consistently correlating with increased competitive ability.

The EphB2-MYC Axis is a Major Determinant of Barrett's Pathobiology and a Therapeutic Vulnerability in Esophageal Cancer

S. Venkitachalam, D. Babu, D. Ravillah, R. M. Katabathula, P. Joseph, S. Singh, B. Udhayakumar, Y. Miao, O. Martinez-Uribe, J. A. Hogue, A. M. Kresak, D. Dawson, T. LaFramboise, J. E. Willis, A. Chak, , K. Guda

This study identifies the EphB2-MYC axis as a key driver of Barrett's Esophagus progression to esophageal adenocarcinoma and a potential therapeutic target.
