Hopf bifurcation and stability in a Beddington-DeAngelis predator-prey model with stage structure for predator and time delay incorporating prey refuge

Open Mathematics, 2019
In this paper, we consider a Beddington-DeAngelis predator-prey system with stage structure for predator and time delay incorporating prey refuge. By analyzing the characteristic equations, we study the local stability of the equilibrium of the system ...

Absorbing Phase Transition in a Four State Predator Prey Model in One Dimension

, 2011
The model of competition between densities of two different species, called predator and prey, is studied on a one dimensional periodic lattice, where each site can be in one of the four states say, empty, or occupied by a single predator, or occupied by

Intertidal Warfare: Synergistic Allelopathy Mediates Spatial Competition between Two Marine Calcareous‐Shelled Sessile Organisms

Advanced Science, EarlyView.
This study reveals a hidden chemical weapon among calcareous‐shelled sessile organisms in the intertidal zone: the barnacle Balanus albicostatus releases a synergistic blend of palmitic acid and 1‐palmitoyl‐sn‐glycero‐3‐phosphocholine as the allelochemical with the inhibitory activity against attachment of the mussel Vignadula atrata, which may mediate

Cooperative hunting in a discrete predator-prey system

, 2018
We propose and investigate a discrete-time predator-prey system with cooperative hunting in the predator population. The model is constructed from the classical Nicholson-Bailey host-parasitoid system with density dependent growth rate.

MDP25‐VDAC3 Complex Orchestrates Actin Remodeling and Mitochondrial Dynamics to Modulate Innate Immunity in Arabidopsis

Advanced Science, EarlyView.
This study reveals that actin remodeling regulates mitochondrial elongation as a defense strategy in plants. Flagellin perception induces fusion‐dependent elongation, supported by cortical actin bundles, to repair damage and boost ATP and ROS production.

Phase transitions in dependence of apex predator decaying ratio in a cyclic dominant system

, 2018
Cyclic dominant systems, like rock-paper-scissors game, are frequently used to explain biodiversity in nature, where mobility, reproduction and intransitive competition are on stage to provide the coexistence of competitors. A significantly new situation

Mechanism‐Driven Screening of Membrane‐Targeting and Pore‐Forming Antimicrobial Peptides

Advanced Science, EarlyView.
To combat antibiotic resistance, this study employs mechanism‐driven screening with machine learning to identify pore‐forming antimicrobial peptides from amphibian and human metaproteomes. Seven peptides are validated, showing minimal toxicity and membrane disruption.

Feedback control and its impact on generalist predator–prey system with prey harvesting

Nonlinear Analysis, 2019
This article examines the effectiveness of feedback control as a management policy on a generalist predator–prey system with prey harvesting. We discuss the result of implementing feedback control with respect to prey and predator separately.

A Non‐Mitophagy Activity of BNIP3L/NIX in Amygdala Glutamatergic Neurons is Essential for Contextual Fear Memory Formation

Advanced Science, EarlyView.
Contextual fear conditioning induces BNIP3L‐dependent mitochondrial fission in glutamatergic neurons of the BLA, independently of mitophagy. Loss of BNIP3L elevates Drp1Ser637 phosphorylation, thereby suppressing mitochondrial fission, compromising ATP production, and attenuating excitatory synaptic transmission.

Extinction and Permanence of a General Predator-Prey System with Impulsive Perturbations

Journal of Applied Mathematics, 2012
A general predator-prey system is studied in a scheme where there is periodic impulsive perturbations. This scheme has the potential to protect the predator from extinction but under some conditions may also serve to lead to extinction of the prey ...
