Something New Under the Sun: Assessing the Relative Influence of Sunlight Irradiance and Temperature on Activity Patterns in a Conspicuous Dragonfly

open access: yesNew Zealand Journal of Zoology, Volume 53, Issue 3, September 2026.
In amberwing dragonfly (Perithemis tenera), solar irradiance in the 550–700 nm range (orange arrows) is only reflected by the colored wings of males (fully orange individuals). Therefore, sunlight intensity may be an important factor driving the effectiveness of their conspicuous wing displays during territorial contests and mating behavior.

Methodological Effects on Plant–Hummingbird Networks: A Comparison of Pollen Load and Focal Observation Approaches in Colombian Andean Ecosystems

open access: yesBiotropica, Volume 58, Issue 5, September 2026.
ABSTRACT Ecological interactions, such as plant–pollinator interactions, are fundamental to maintaining biodiversity and sustaining ecosystem functions. In tropical ecosystems, hummingbirds serve as key pollinators due to their specialized morphological traits, which facilitate plant–pollinator interactions.

Pronounced and prevalent intersexuality does not impede the ‘Demon Shrimp’ invasion

open access: yes, 2014
Crustacean intersexuality is widespread and often linked to infection by sex-distorting parasites. However, unlike vertebrate intersexuality, its association with sexual dysfunction is unclear and remains a matter of debate.
