We study a discrete time model of the growth of two species of plankton with competitive and allelopathic effects on each other N1(k + 1) = N1(k)exp{r1(k)− a11(k)N1(k)− a12(k)N2(k) − b1(k)N1(k)N2(k)}, N2(k + 1) = N2(k)exp{r2(k) − a21(k)N1(k) − a22(k) N2(k)− b2(k)N1(k)N2(k)}. A set of sufficient conditions is obtained for the existence of multiple positive periodic solutions for this model. The ...

Abstract The sustainable management of the environment and crop production in modern agriculture involves dealing with challenges from climate change, environmental pollution, depletion natural resources, as well pressure to cope dependence on agricultural inputs. Balancing productivity sustainability is one main for worldwide. emergence weeds resistant synthetic herbicides generates huge econo...

Many coral reefs have phase shifted from coral to macroalgal dominance. Ocean acidification (OA) due to elevated CO2 is hypothesised to advantage macroalgae over corals, contributing to these shifts, but the mechanisms affecting coral-macroalgal interactions under OA are unknown. Here, we show that (i) three common macroalgae are more damaging to a common coral when they compete under CO2 conce...

BACKGROUND AND AIMS Is the release of allelochemicals by the dominant tussock grass Festuca paniculata responsible for its dominance by inhibiting growth of neighbour grasses in subalpine grasslands? As such a community is also structured by mowing practices, what could be the impact of mowing on allelopathy? METHODS A design was used that isolated allelopathy from resource competition by sep...

Allelochemicals, otherwise known as the inherent silent tool of self-protection among plants, have witnessed a dramatic increase in research in recent years. The potentials of these allelochemicals becoming new bioactive chemicals useful for more sustainable agriculture and safe food production for humanity have been realized for quite sometime. We have recently started a new project entitled, ...

We study the properties of almost periodic solutions for a general discrete system of plankton allelopathy with feedback controls and establish a theorem on the uniformly asymptotic stability of almost periodic solutions.
