Integrative Taxonomy of Costa Rican Tetrigidae (Orthoptera) Reveals Eight New Species

open access: yesDiversity
Tetrigidae is one of the largest orthopteran families, but very few studies so far have integrated molecular and morphological data. Unsurprisingly, few species have been DNA barcoded, and the unresolved taxonomy makes Tetrigidae a difficult group to ...

What's on the menu? Examining native apex‐ and invasive meso‐predator diets to understand impacts on ecosystems

open access: yesEcological Solutions and Evidence, Volume 6, Issue 2, April–June 2025.
When comparing the diets of native and invasive predator species in semi‐arid Australia, we found that native apex dingoes primarily consume large kangaroos, wallabies and emus, whereas invasive cats and foxes consume smaller prey groups, including 8–9 times the volume of threatened and vulnerable native mammals.

Role of body size and shape in animal camouflage

open access: yesEcology and Evolution, Volume 14, Issue 5, May 2024.
In this review, we analyzed the research on the impact of animal body size and shape on their camouflage and outlined existing research issues and challenges. Overall, we found a negative correlation between body size and the effectiveness of disruptive coloration and background matching as camouflage strategies.

The effect of micro‐level and macro‐level signalling on learning with 360° videos

open access: yesApplied Cognitive Psychology, Volume 38, Issue 2, March/April 2024.
Abstract 360° videos raised the attention of educators, as they can mediate complex environments in educational settings. However, learning irrelevant cognitive strains might be imposed because it is necessary to navigate through spherical material. These downsides could be compensated by using signalling techniques. In a two (macro‐level vs.
