Coastal fisheries adaptations to increasing climate change exposure in Japan
People and Nature, Volume 6, Issue 6, Page 2339-2356, December 2024.Abstract Climate change‐driven ocean warming is altering the geographic ranges of species, leading to a poleward shift of tropical species into temperate regions (tropicalisation). This threatens the native marine community assemblages by changing the availability of traditional marine resources, thus impacting the livelihood and well‐being of coastal ...

Impact of fear in a prey-predator system with herd behaviour
Computational and Mathematical Biophysics, 2021 Fear of predation plays an important role in the growth of a prey species in a prey-predator system. In this work, a two-species model is formulated where the prey species move in a herd to protect themselves and so it acts as a defense strategy.

Solvability of boundary value problems for fractional order elastic beam equations
Advances in Differential Equations, 2014 In this article, the existence results for solutions of a boundary value problem for nonlinear singular fractional order elastic beam equations are established. The analysis relies on the well-known Schauder’s fixed point theorem. MSC:92D25, 34A37, 34K15.

An eco-epidemiological model with predator switching behavior
Computational and Mathematical Biophysics, 2023 Switching mechanism is adopted by predator populations when they are provided with two types of prey: susceptible and infected. In this study, we propose a modification of an eco-epidemiological model with the predator switching mechanism.

An analysis of hybrid impulsive prey-predator-mutualist system on nonuniform time domains
Computational and Mathematical BiophysicsIn this work, we propose a hybrid impulsive prey-predator-mutualist model on nonuniform time domains. We have investigated the permanence/persistence results for the proposed model using the comparison theorems of impulsive differential equations and ...

Global Stability Analysis of a General Model of Zika Virus
Nonautonomous Dynamical Systems, 2019 Mathematical models of Zika virus dynamics are relatively new, and they mostly focus on either vector and horizontal, or vector and vertical transmission only.

Existence of Bistable Waves in a Competitive Recursion System with Ricker Nonlinearity [PDF]
, 2013 Using an abstract scheme of monotone semiflows, the existence of bistable traveling wave solutions of a competitive recursion system with Ricker nonlinearity is established. The traveling wave solutions formulate the strong inter-specific actions between

Stability analysis of a host parasite model
, 2013 Host parasite models are similar to host parasitoid models except that the parasite does not necessarily kill the host. Leslie/Gower model (Leslie and Gower in Biometrika 47(3/4):219-234, 1960) played a historical role in ecology.

A two-strain ecoepidemic competition model
, 2014 In this paper we consider a competition system in which two diseases spread by contact. We characterize the system behavior, establishing that only some configurations are possible.
