Assessing the Impact of Urbanization on Grasshopper Behaviour—A Fieldwork Approach

Journal of Applied Entomology, EarlyView.
ABSTRACT Urbanization is one of the most significant land‐use changes globally, profoundly impacting biodiversity across taxa. Insects, including grasshoppers (Orthoptera), are particularly sensitive to urban pressures, often exhibiting both morphological and behavioural adaptations.

Control Strategies in Guanine Biocrystallization

Angewandte Chemie, Volume 138, Issue 18, 27 April 2026.
Biological guanine crystals produce spectacular photonic phenomena in animals and hold great promise as new, sustainable optical materials. We review how organisms precisely control the structure, morphologies, and resulting optical properties of these crystals using a set of ingenious ‘design’ strategies, including control of pH, template‐directed ...

Gut Microbiome Diversity, Functional Potential, and Ecological Relevance of Hottentotta tamulus

MicrobiologyOpen, Volume 15, Issue 5, October 2026.
Long‐read 16S sequencing uncovers the gut microbiome of H. tamulus. A highly conserved and low‐diversity bacterial community dominates the gut fauna. Bacillus and Mycoplasma lineages emerge as predominant candidate endosymbionts. Exploratory profiles reveal potential sex‐specific trends in microbial abundance.

Health Expectations, Volume 29, Issue 5, October 2026.
ABSTRACT Introduction Young‐onset dementia (YOD) is a term used when people demonstrate symptoms or are diagnosed with dementia before 65 years of age. YOD can be challenging to diagnose because health practitioners often do not initially consider dementia as the cause of someone's change in health or function in their 40 s, 50 s or even early 60 s ...

Urban Environments Aid Invasion of Brown Widows (Theridiidae: Latrodectus geometricus) in North America, Constraining Regions of Overlap and Mitigating Potential Impact on Native Widows

Frontiers in Ecology and Evolution, 2021
Urbanization is a major cause of biotic homogenization and habitat fragmentation for native communities. However, the role of urbanization on the success of biological invasions on a continental scale has yet to be explored.
