A new method to investigate almost periodic solutions for an Nicholson's blowflies model with time-varying delays and a linear harvesting term.

open access: yesMathematical biosciences and engineering : MBE, 2019
In this paper, a delayed Nicholson's blowflies model with a linear harvesting term is investigated. By transforming the model into an equivalent integral equation, and applying a fixed point theorem inc ones, we establish a sufficient condition which ...

Positive periodic solutions generated by impulses for the delay Nicholson's blowflies model

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2016
In this paper, by using Krasnoselskii's fixed point theorem, we study the existence and multiplicity of positive periodic solutions for the delay Nicholson's blowflies model with impulsive effects.

Pseudo-almost periodicity on a Nicholson’s blowflies model involving multiple iterative terms

open access: yesAdvances in Continuous and Discrete Models
This paper focuses on the investigation of a class of non-autonomous Nicholson’s blowflies models incorporating multiple iterative terms. Through the construction of suitable invariant sets and the integration of differential inequality techniques with ...

Generation cycles in experimental populations of a multivoltine insect

open access: yesJournal of Animal Ecology, Volume 95, Issue 5, Page 782-794, May 2026.
Although theory suggests various mechanisms by which environmental and ecological factors may drive generational fluctuations, our field‐cage experiment is the first to demonstrate how internal dynamics and external disturbances jointly produce synchronised, large‐scale outbreak cycles.

Complex Dynamics on the Routes to Chaos in a Discrete Predator‐Prey System with Crowley‐Martin Type Functional Response

open access: yesDiscrete Dynamics in Nature and Society, Volume 2018, Issue 1, 2018., 2018
We present in this paper an investigation on a discrete predator‐prey system with Crowley‐Martin type functional response to know its complex dynamics on the routes to chaos which are induced by bifurcations. Via application of the center manifold theorem and bifurcation theorems, occurrence conditions for flip bifurcation and Neimark‐Sacker ...

Permanence, Extinction, and Almost Periodic Solution of a Nicholson's Blowflies Model with Feedback Control and Time Delay

open access: yesDiscrete Dynamics in Nature and Society, 2013
A Nicholson's blowflies model with feedback control and time delay is studied. By applying the comparison theorem of the differential equation and fluctuation lemma and constructing a suitable Lyapunov functional, sufficient conditions which guarantee ...

Mosquito‐derived ingested DNA as a tool for monitoring terrestrial vertebrates within a peri‐urban environment

open access: yesEcosphere, Volume 16, Issue 1, January 2025.
Abstract Global biodiversity is declining at an alarming rate. Consequently, there is a pivotal need to determine the occurrences and distributions of threatened species. Monitoring and detection approaches are traditionally reliant on capture (traps and cameras), as well as observations.
