Lyapunov stability analysis for nonlinear delay systems under random effects and stochastic perturbations with applications in finance and ecology

Advances in Difference Equations, 2021
This manuscript is involved in the study of stability of the solutions of functional differential equations (FDEs) with random coefficients and/or stochastic terms.

A Comparative Study of iDNA and airDNA for Biodiversity Assessments in Tropical Forest Fragments

Environmental DNA, Volume 8, Issue 3, May–June 2026.
Comparing invertebrate‐derived DNA and airborne eDNA across fragmented tropical forests, we show that iDNA recovers higher vertebrate richness from fewer samples, while airDNA offers greater field reliability. Together, both methods capture functional diversity gradients, supporting a combined approach for agroforestry biodiversity monitoring ...

Generation cycles in experimental populations of a multivoltine insect

Journal 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.

Evaluating the Molecular Potential and Interpretability of DNA in Historical Spirit Collection Media

Molecular Ecology Resources, Volume 26, Issue 4, May 2026.
ABSTRACT Advancements in historical genomics increasingly leverage museum collections to study past ecosystems, species interactions and biodiversity. Formalin‐fixed, ethanol‐preserved specimens, once thought inaccessible to molecular analyses due to DNA degradation, are emerging as valuable genomic resources.

Inventario de los Calyptratae (Insecta: Diptera) saprófagos en los espacios verdes urbanos de la ciudad de Buenos Aires [PDF]

, 2015
El inventario de la biodiversidad es una tarea urgente para la conservación de los insectos. En particular, los espacios verdes urbanos (áreas sin edificaciones) dentro de entornos urbanos son un elemento fundamental para el mantenimiento y restauración ...

Dichotomy results for delay differential equations with negative Schwarzian

, 2008
We gain further insight into the use of the Schwarzian derivative to obtain new results for a family of functional differential equations including the famous Wright's equation and the Mackey-Glass type delay differential equations.

Integrating Physiological Rates of Thermal Stress and Repair Predicts Heat Failure During Temperature Fluctuations

Ecology Letters, Volume 29, Issue 5, May 2026.
As the frequency and intensity of extreme heat events are increasing, it is urgently important to understand how organisms respond to and recover from heat stress. Here we extend the existing Thermal Death Time framework to include the antagonistic processes of accumulation and repair of thermal injury, which operate at stressful and permissive ...

Armadilha atrativa padronizada e de baixo custo para coleta de Diptera (Insecta) atraídos por substratos proteicos

Entomological Communications
The use of baited traps is essential for sampling necrophagous Diptera Linnaeus, 1758 in both ecological and forensic studies. Ferreira's trap is a widely used model in Brazil; however, traditional versions can present logistical challenges under field ...

Genetic Diversity and Phylogenetic Relationships of Coevolving Symbiont-Harboring Insect Trypanosomatids, and Their Neotropical Dispersal by Invader African Blowflies (Calliphoridae)

Frontiers in Microbiology, 2018
This study is about the inter- and intra-specific genetic diversity of trypanosomatids of the genus Angomonas, and their association with Calliphoridae (blowflies) in Neotropical and Afrotropical regions. Microscopic examination of 3,900 flies of various
