The effect of climate warming on species' physiological parameters, including growth rate, mortality rate and handling time, is well established from empirical data. However, with an alarming rise in global temperature more than ever, predicting the interactive influence these changes mutualistic communities remains uncertain. Using 139 real plant-pollinator networks sampled across globe a modelling approach, we study impact individual thermal responses communities. We show that at low...
Many complex networks are known to exhibit sudden transitions between alternative steady states with contrasting properties. Such a transition demonstrates network's resilience, which is the ability of system persist in face perturbations. Most research on network resilience has focused from one equilibrium state an state. Although presence non-equilibrium dynamics some nodes may advance or delay and give early warning signals impending collapse, it not been studied much context resilience....
Anthropogenic global warming in this century can act as a leading factor for large scale species extinctions the near future. Species, order to survive, need develop dispersal strategies depending upon their environmental niche. Based on empirical evidence only few previous studies have addressed how evolve with changing temperature. However, analytical tractability, there is an explicit model ask temperature-dependent alters ecological dynamics. We investigate persistence of spatial model,...

Network structure or connectivity patterns are critical in determining collective dynamics among interacting species ecosystems. Conventional research on persistence spatial populations has focused static network structure, though most real structures change time, forming time-varying networks. This raises the question, metacommunities, how does pattern of synchrony vary with temporal evolution structure. The synchronous known to reduce metacommunity persistence. Here we consider a...
Consumer-resource cycles are widespread in ecosystems, and seasonal forcing is known to influence them profoundly. Typically, perturbs an ecosystem with time-varying frequency; however, previous studies have explored the dynamics of such systems under oscillatory constant frequency. Studies effect frequency on stability lacking. Here we investigate isolated network models a cyclic consumer-resource driving subjected modulation. We show that modulation can induce system form stable...
