Entomologia Experimentalis et Applicata, Volume 171, Issue 4, Page 258-267, April 2023., 2023 Cryptic colouration is an adaptative mechanism against predation. In a computer experiment, we analysed the cryptic effectiveness of male and female colour patterns of Sphenarium zapotecum (Orthoptera: Pyrogomorphidae) grasshoppers. Males were most disruptive and females had higher background matching.

The effect of microlevel and macrolevel signaling on learning with 360° videos
Applied Cognitive Psychology, Volume 37, Issue 1, Page 232-246, January/February 2023., 2023 Abstract The application of 360° videos raised the attention of educators and researchers, as it appears to be an approachable option to mediate complete environments in educational settings. However, challenges emerge from the perspective of educational psychology.

Reduced predation risk for melanistic pygmy grasshoppers in post‐fire environments
Ecology and Evolution, 2012 AbstractThe existence of melanistic (black) color forms in many species represents interesting model systems that have played important roles for our understanding of selective processes, evolution of adaptations, and the maintenance of variation. A recent study reported on rapid evolutionary shifts in frequencies of the melanistic forms in replicated ...

COEVOLUTION OF COLOR PATTERN AND THERMOREGULATORY BEHAVIOR IN POLYMORPHIC PYGMY GRASSHOPPERS TETRIX UNDULATA [PDF]
Evolution, 2002 Ectothermic organisms, such as insects and reptiles, rely on external heat sources to control body temperature and possess physiological and behavioral traits that are temperature dependent. It has therefore been hypothesised that differences in body temperature resulting from phenotypic properties, such as color pattern, may translate into selection ...

Bite force estimates and morphological correlations of jaw muscles in parrots
The Anatomical Record, EarlyView.Abstract Parrots (Order: Psittaciformes) are renowned for their high bite force (BF) and morphological correlates thereof, including a highly mobile skull and two unique mandibular adductor muscles—m. pseudomasseter and m. ethmomandibularis, with the former being hypothesized to increase force output.

A new tribe of the pygmy grasshoppers subfamily Cladonotinae (Orthoptera: Tetrigidae)
Far Eastern entomologist, 2023 New tribe Epitettigini trib. n. is proposed for five genera with uncertain tribal position within subfamily Cladonotinae. It consists of the genera Epitettix Hancock, 1907, Devriesetettix Tumbrinck, 2014, Ingrischitettix Tumbrinck, 2014, Pseudohyboella Günther, 1938, and Yunnantettix Zheng, 1995.

Rapid ideal habitat selection in a homogeneous environment
Ecosphere, Volume 17, Issue 3, March 2026.Abstract Studies of density‐dependent habitat selection typically assess choices between two or more distinctly different habitat opportunities. Although such studies can clearly document habitat choice, they cannot unambiguously differentiate the effects of density from underlying differences in habitat and their associated cues for choosing some ...
