Multiple Periodic Solutions for Discrete Nicholson’s Blowflies Type System

Abstract and Applied Analysis, 2014
This paper is concerned with the existence of multiple periodic solutions for discrete Nicholson’s blowflies type system. By using the Leggett-Williams fixed point theorem, we obtain the existence of three nonnegative periodic solutions for discrete ...

Effect of temperature on the rate of ageing: an experimental study of the blowfly Calliphora stygia. [PDF]

PLoS ONE, 2013
All organisms age, the rate of which can be measured by demographic analysis of mortality rates. The rate of ageing is thermally sensitive in ectothermic invertebrates and we examined the effects of temperature on both demographic rates of ageing and on ...

Environmental Drivers on Blue Tit Nest Microbiome: An Experimental Study

Ecology and Evolution, Volume 16, Issue 7, July 2026.
Elevated humidity and temperature altered nest microbial composition and its associations with parasitism and nestling condition. These findings identify nest microclimate as an important driver of nest microbiomes with consequences for avian development.

Expanding the Ecological Application of Invertebrate‐Derived DNA (iDNA) for Monitoring Terrestrial Mammals Using a Single‐Species Approach

Environmental DNA, Volume 8, Issue 4, July‐August 2026.
A novel single‐species, invertebrate‐derived eDNA (iDNA) method is presented for identifying European Brown Bear presence. Fly‐borne bear DNA remains readily identifiable for 24 h within flies and can be detected when just one fly in 20 has fed on bear scat. The method is effective both in laboratory and field settings. ABSTRACT Successful conservation

Recovery of male DNA acquired from carrion‐feeding insects in a simulated sexual assault scenario

Journal of Forensic Sciences, Volume 71, Issue 4, Page 1576-1591, July 2026.
Abstract When bodies of sexual assault victims are discovered in advanced stages of decomposition, the recovery of direct DNA evidence is often compromised, posing a challenge in criminal investigations. This study aimed to determine insect colonization and succession patterns on pig carcasses inoculated with semen and to assess the feasibility of ...

Insects and Survival: A Review of Primary and Secondary Defense Strategies

Entomologia Experimentalis et Applicata, Volume 174, Issue 7, Page 601-624, July 2026.
Based on a review of three decades of literature, insect defense mechanisms are classified into primary (I) and secondary (II) mechanisms of behavioral, morphological, and chemical nature. These mechanisms have been recorded in 22 (I) and 20 (II) orders, respectively.

Whole System Ecohydrological Change Following Natural Flood Management and a Five‐Year Beaver Reintroduction Trial

Ecohydrology, Volume 19, Issue 4, June 2026.
ABSTRACT Once‐common beavers have been absent from the British landscape for centuries, but wild beaver populations have returned in recent years as part of reintroduction schemes, including releases into monitored enclosures. In North Yorkshire, such a release of Eurasian beavers took place in 2019.

Beyond birds: rethinking bird‐centered pathogen models in light of insect migration

Ecography, Volume 2026, Issue 6, June 2026.
Migration redistributes biomass, nutrients, and pathogens across ecosystems. For decades, migratory birds have been treated as the default long‐distance pathogen vectors, shaping both conceptual frameworks and empirical models of disease ecology.
