A graph based advection framework for climate-driven species distribution
Pranali Roy Chowdhury, Soumyendu Raha
Climate change is reshaping species interactions and movement across fragmented landscapes. Despite this, most mathematical models assume random diffusion, overlooking the influenc…
Pollutant-induced changes in fish pigmentation and spatial patterns
Pranali Roy Chowdhury, Tian Xu Wang, Abbey MacDonald +2
Pigmentation abnormalities, ranging from hypo- to hyperpigmentation, can serve as biomarkers of developmental disruption in fish exposed to environmental contaminants. However, the…
The silent threat of methane to ecosystems: Insights from mechanistic modelling
Pranali Roy Chowdhury, Tianxu Wang, Shohel Ahmed +1
Over the past century, atmospheric methane levels have nearly doubled, posing a significant threat to ecosystems. Despite this, studies on its direct impact on species interactions…
Normal form for singular Bautin bifurcation in a slow-fast system with Holling type III functional response
Tapan Saha, Pranali Roy Chowdhury, Pallav Jyoti Pal +1
Over the last few decades, complex oscillations of slow-fast systems have been a key area of research. In the theory of slow-fast systems, the location of singular Hopf bifurcation…
Attractors and long transients in a spatio-temporal slow-fast Bazykin's model
Pranali Roy Chowdhury, Sergei Petrovskii, Vitaly Volpert +1
Spatio-temporal complexity of ecological dynamics has been a major focus of research for a few decades. Pattern formation, chaos, regime shifts and long transients are frequently o…
Stationary and non-stationary pattern formation over fragmented habitat
Malay Banerjee, Swadesh Pal, Pranali Roy Chowdhury
Spatio-temporal pattern formation over the square and rectangular domain has received significant attention from researchers. A wide range of stationary and non-stationary patterns…
Oscillations and pattern formation in a slow-fast prey-predator system
Pranali Roy Chowdhury, Sergei Petrovskii, Malay Banerjee
We consider the properties of a slow-fast prey-predator system in time and space. We first argue that the simplicity of prey-predator system is apparent rather than real and there…
