Dynamical study of the theta-logistic predator-prey model incorporating gregarious behavior of prey

open access: yesMathematics in Applied Sciences and Engineering, 2023
Relation between species and their livelihood environment in ecological systems is very complex. For that reason, in order to study predator-prey  relations, modeling is essential in biomathematics.

Influence of habitat complexity on the prey mortality in IGP system involving insect predators (Heteroptera) and prey (Diptera): Implications in biological control.

open access: yesPLoS ONE, 2022
Intraguild predation (IGP) is common in the freshwater insect communities, involving a top predator, intraguild prey (IG prey) and a shared prey. Influence of the habitat complexity on the prey-predator interactions is well established through several ...

Evolutionary Diversification of Prey and Predator Species Facilitated by Asymmetric Interactions. [PDF]

open access: yesPLoS ONE, 2016
We investigate the influence of asymmetric interactions on coevolutionary dynamics of a predator-prey system by using the theory of adaptive dynamics.

Competition and Dispersal in Predator–Prey Waves

open access: yesTheoretical Population Biology, 1999
Dispersing predators and prey can exhibit complex spatio-temporal wave-like patterns if the interactions between them cause oscillatory dynamics. We study the effect of these predator-prey density waves on the competition between prey populations and between predator populations with different dispersal strategies.

Invasion of a stream food web by a new top predator. [PDF]

open access: yes, 1999
PhDA large predator, the nymph of the dragonfly Cordulegaster boltonii (Anisoptera) (Donovan), has recently invaded Broadstone Stream, an acid headwater in southern England.

The behavioral response of prey fish to predators: the role of predator size [PDF]

open access: yesPeerJ, 2017
Predation is one of the key factors governing patterns in natural systems, and adjustments of prey behaviors in response to a predator stimulus can have important ecological implications for wild fish.

Prey–predator optimal harvesting mathematical model in the presence of toxic prey under interval uncertainty

open access: yesScientific African, 2023
This paper explores a multispecies prey–predator harvesting system based on Lotka–Volterra model with two preys (palatable and toxic prey) and one predator with interval biological parameters.

Invertebrate attack rates in crop fields are driven by prey toughness rather than size

open access: yesBasic and Applied Ecology
Insect pests vary in size and toughness across species and life stages, and are attacked to varying degrees by different predators. Feeding experiments suggest that both prey and predator (e.g. carabid) traits shape these predator–prey interactions. Here,

Coordinated Architectural and Chemical Reinforcement in the Crushing Mandible of a Soldier Termite

open access: yesAdvanced Functional Materials, EarlyView.
The crushing mandible of a soldier termite withstands substantial biting loads despite lacking mineral. Its cuticle is partitioned: convex teeth pair hardness and zinc enrichment with aligned chitin fibers for contact durability, while stiffer concave regions between teeth carry bending loads.

Effects of Behavioral Tactics of Predators on Dynamics of a Predator-Prey System

open access: yesAdvances in Mathematical Physics, 2014
A predator-prey model incorporating individual behavior is presented, where the predator-prey interaction is described by a classical Lotka-Volterra model with self-limiting prey; predators can use the behavioral tactics of rock-paper-scissors to dispute
