Resilience Practices and Post‐Traumatic Growth Among Sudanese IDPs

Conflict Resolution Quarterly, Volume 43, Issue 4, Page 629-641, Summer 2026.
ABSTRACT In this paper we examine the resilience of internally displaced persons (IDPs) in Sudan who have endured various forms of suffering resulting from being targeted or trapped by militants involved in large‐scale violence. Upon escaping the conflict zones, the civilians exhibit strength, adaptability, and wisdom in the face of various threats to ...

Alternative Control of the Leaf-Cutting Ant Atta bisphaerica Forel (Hymenoptera: Formicidae) Via Homeopathic Baits

Sociobiology, 2013
Leaf-cutting ants are pests that afflict diverse crops, and are most efficiently controlled by chemical methods that are widely utilized. Other methods have been investigated aiming to efficiently control these insects while reducing the environmental ...

Direct and indirect effects of leaf-cutting ants (Atta) on vegetation dynamic in a neotropical savanna

, 2013
Ants are fundamental organisms in the dynamics of several terrestrial ecosystems. In the Neotropical region, leaf-cutting ants detach because their herbivory activity and nest construction have direct and indirect effects on grow, reproduction and ...

Wake Up and Smell the Infected Bees: Volatile Cues of Vairimorpha Infection in Honey Bees

Ecology and Evolution, Volume 16, Issue 6, June 2026.
Infection can modify host volatile emissions, yet effects in adult honey bees remain unexplored. Using dynamic headspace sampling and GC × GC–MS, we show that Vairimorpha spp. infection significantly alters the volatile profile of adult worker honey bees over a 14‐day time series, producing stage‐specific shifts in multivariate odour structure.

The Cognitive Foundations of Teaching

Evolutionary Anthropology: Issues, News, and Reviews, Volume 35, Issue 2, June 2026.
ABSTRACT The propensity to teach is vital to human cultural evolution and to our ecological dominance of the planet, but its cognitive foundations remain poorly understood. Traditional explanations argue that teaching hinges on particular cognitive pre‐requisites, such as Theory of Mind.

Lifespan Trajectories of Asymmetry in White Matter Tracts

Human Brain Mapping, Volume 47, Issue 8, June 1, 2026.
(A) Large‐scale lifespan modeling of white matter asymmetry. Diffusion MRI data from 35,000+ individuals (0‐100 years) across 50 cohorts were used to generate normative lifespan trajectories of white matter asymmetry. Thirty bilateral tracts were segmented, and microstructural (FA, MD, AD, RD) and macrostructural (volume, length) features were ...

Diversity of Resilin Incidence in the Insect Leg

Journal of Morphology, Volume 287, Issue 6, June 2026.
Resilin incidences in the insect cuticle are commonly detected by fluorescence microscopy using the property of Resilin protein matrices to emit blue light after excitation with UV light. This indirect method produces significant background signal.

Fire buffers drought impacts on reproduction in a resprouting Mediterranean shrub

Oikos, Volume 2026, Issue 6, June 2026.
Fire and drought increasingly co‐occur, exposing plants to greater drought stress during post‐fire resprouting. Yet, the effect of this combination of disturbances on plant fitness remains poorly understood. Here, we examine how post‐fire resprouting influences reproductive success under drought conditions in the Mediterranean shrub Anthyllis ...
