Reexamining Sexual and Species Recognition in Butterflies: The Partner‐Hazard Space Framework

Ecology and Evolution, Volume 16, Issue 8, August 2026.
Our review found no evidence that butterflies recognize the same sex or their own species. Behaviors previously interpreted as sexual or species recognition are indistinguishable from those interpreted as mate choice. Butterfly interactions can therefore be explained by assuming a sexual‐partner template that elicits mating behavior and a hazard ...

Departing With the Wind: Spring Migration Timing in Brent Geese From Their Most Important Staging and Wintering Site, the Wadden Sea World Heritage Site

Ecology and Evolution, Volume 16, Issue 8, August 2026.
The timing of migratory departure reflects a balance between endogenous schedules and transient environmental opportunities. By linking GPS‐derived departure events with hourly atmospheric data, we demonstrate that wind assistance strongly increases departure probability in Brent Geese, while this selectivity weakens over time as migratory urgency ...

Universal vortex formation time of flapping flight

Proceedings of the National Academy of Sciences
Biological flyers periodically flap their appendages to generate aerodynamic forces. Extensive studies have made significant progress in explaining the physics behind their propulsion in cruising by developing scaling laws of their flight kinematics.

Geolocation with a magnetic sensor

Methods in Ecology and Evolution, Volume 17, Issue 8, Page 2395-2407, August 2026.
Abstract Many migratory animals use spatial variation in the Earth's magnetic field for orientation and navigation. This raises the possibility of exploiting these same cues to geolocate and track migratory animals throughout their annual journeys. Magnetic‐based geolocation could be particularly valuable for small aerial and aquatic species, for which

A Century Later: Taxonomic Review of the Neotropical Genus Hyptiocheta Becker, 1922 (Diptera: Dolichopodidae), With Description of Three New Andean Species

Austral Entomology, Volume 65, Issue 3, August 2026.
ABSTRACT The previously monotypic Neotropical genus Hyptiocheta Becker, 1922 is reviewed. Hyptiocheta convexa Becker, 1922 is redescribed, and three new species are described and illustrated from South America: H. archaeoptera Quevedo, Soares & Lamas sp. nov. (Ecuador), H. chuspi Quevedo, Soares & Gutiérrez‐Bustamante sp. nov. (Peru) and H.

Trimerous magnoliid flowers with a unique set of floral and pollen traits from the Late Cretaceous of Southern Bohemia (Czech Republic)

New Phytologist, Volume 251, Issue 4, Page 2266-2283, August 2026.
Morphospace position and phylogenetic placements of Trimeriantha monopolyada. Summary Floral structure is a key aspect of angiosperm diversity. Recent research revealed that significant floral disparity was already present in the Cretaceous. However, our understanding of early floral diversity remains limited, as it is directly dependent on the fossil ...

Temporal Variations of Jupiter's Plasma Disk Observed by Juno

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract In Jupiter's magnetosphere, a key question is how plasma is transported outward from its source near Io to the distant magnetotail. Since 2016, the plasma disk has been extensively observed by the Juno mission. Using plasma data from the JADE instrument, we perform an analysis revealing significant temporal variation. For different Juno orbits,
