Sexual dimorphism and geographical male polymorphism in the ghost moth Hepialus humuli (Lepidoptera: Hepialidae): Scale ultrastructure and evolutionary aspects

open access: yesEuropean Journal of Entomology, 2009
Throughout most of its range the Palaearctic moth Hepialus humuli shows a striking sexual dimorphism correlated with a dimorphism in wing scale ultrastructure.

3D anatomical atlas of the heads of male and female adult Chamaeleo calyptratus

open access: yesThe Anatomical Record, Volume 309, Issue 8, Page 1937-1969, August 2026.
The veiled chameleon is a model organism in reptile development research. Utilizing contrast‐enhanced microCT and deep learning segmentation models, we have generated the first digital atlases of the skull, nervous system, cranial muscles and hyolingual muscles.

Sexual dimorphism in the structural colours of the wings of the black soldier fly (BSF) Hermetia illucens (Diptera: Stratiomyidae)

open access: yesScientific Reports
The black soldier fly (BSF) Hermetia illucens (Diptera: Stratiomyidae) plays a significant role at the larval stage in the circular economy due to its ability to convert organic waste into valuable products for energy, food, feed, and agricultural ...

Biometric variability and sexual size dimorphism in the Great Knot Calidris tenuirostris

open access: yesThe European Zoological Journal
The Great Knot is a species from the Scolopacidae family of waders migrating within the East Asian-Australasian Flyway, and studies on this species have contributed greatly to understanding of migration ecophysiology and migration strategies in long ...

Comparative Neuroanatomy of Hydrothermal Vent Shrimps: Ecological Differentiation Among Four Alvinocaridid Species

open access: yesJournal of Comparative Neurology, Volume 534, Issue 8, August 2026.
Hydrothermal vent shrimps share a conserved brain architecture with enlarged mushroom bodies and terminal medullae, shaped by similar environmental pressures. Despite this similarity, some anatomical features near the brain vary between species, suggesting that some ecological factors, such as microhabitat and trophic strategies, also influence nervous

Latitudinal gradient in response of wing polymorphism to photoperiod in a flightless bug, Pyrrhocoris apterus (Heteroptera: Pyrrhocoridae)

open access: yesEuropean Journal of Entomology, 2001
The aim of this study was to determine if there is a latitudinal gradient in the photoperiodic regulation of wing dimorphism in the flightless bug, Pyrrhocoris apterus (L.).

Home Range and Habitat Selection of the Endangered Red Goshawk (Erythrotriorchis radiatus) Across Australia's Tropical Savannas

open access: yesEcology and Evolution, Volume 16, Issue 8, August 2026.
We used long‐term GPS tracking to quantify home‐range size and habitat selection of the endangered Red Goshawk across tropical savannas of northern Australia. Red Goshawks occupied extensive overall home ranges, with well‐defined core ranges centred on nest sites.

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

open access: yesEcology 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 ...

Life history correlates of adult size in the malaria vector Anopheles darlingi

open access: yesMemorias do Instituto Oswaldo Cruz, 1995
Adult dry weights of laboratory-reared Anopheles darlingi were highly correlated with wing lengths, which were used to estimate size variation in natural populations of this species.

Defying Expectations: Extended Lifespan and Age‐Related Telomere Dynamics in the Tropical Bat Species, Molossus molossus

open access: yesEcology and Evolution, Volume 16, Issue 8, August 2026.
We investigated age‐related telomere dynamics in the tropical bat Molossus molossus using a long‐term mark‐recapture study of 492 individuals from Panama. We documented a female surviving to at least 13 years, more than doubling the previously reported maximum lifespan, while finding no consistent evidence of age‐related telomere shortening.
