Rescue or murder? The effect of prey adaptation to the predator subjected to fisheries

Ecology and Evolution
The concept of “indirect evolutionary rescue” refers to the evolutionary adaptation of an interacting species that can save a focal species from extinction in an unfavorable environment.

A Study of a Diseased Prey-Predator Model with Refuge in Prey and Harvesting from Predator

Journal of Applied Mathematics, 2018
In this paper, a mathematical model of a prey-predator system with infectious disease in the prey population is proposed and studied. It is assumed that there is a constant refuge in prey as a defensive property against predation and harvesting from the ...

Edible Pneumatic Battery for Sustained and Repeated Robot Actuation

Advanced Science, EarlyView.
This work presents an edible energy source and valve system to power soft, pneumatically driven edible robots. A chemical reaction between sodium bicarbonate and citric acid generates carbon dioxide gas, and a pressure‐triggered edible valve enables self‐repetitive motion of the edible actuator.

Comprehensive Profiling of N6‐methyladnosine (m6A) Readouts Reveals Novel m6A Readers That Regulate Human Embryonic Stem Cell Differentiation

Advanced Science, EarlyView.
This research deciphers the m6A transcriptome by profiling its sites and functional readout effects: from mRNA stability, translation to alternative splicing, across five different cell types. Machine learning model identifies novel m6A‐binding proteins DDX6 and FXR2 and novel m6A reader proteins FUBP3 and L1TD1.

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.

A predator–prey system with L1 data

Journal of Mathematical Analysis and Applications, 2003
The authors consider a system of semilinear differential equations of parabolic type modeling a predator-prey system in heterogeneous habitats. Preys are assumed to follow a logistic growth in the absence of predation, and predators are assumed to feed on preys with a Holding type II functional response to prey density.
