Portable X‐Ray Fluorescence Spectrometry in the Investigation of Coastal Rock Art at the Pedra do Maçaranduba Site (Piauí, Brazil)

open access: yesX-Ray Spectrometry, EarlyView.
ABSTRACT This study aims to understand the composition and application of red rock art from the Pedra do Maçaranduba archaeological site, located on the coast of Piauí (Brazil). This is a pioneering study of archaeological rock art sites found in the coastal region of Brazil.

Optimal performance design of bat algorithm: An adaptive multi‐stage structure

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
Abstract The bat algorithm (BA) is a metaheuristic algorithm for global optimisation that simulates the echolocation behaviour of bats with varying pulse rates of emission and loudness, which can be used to find the globally optimal solutions for various optimisation problems. Knowing the recent criticises of the originality of equations, the principle

The Hill‐Type Equation Reveals the Regulatory Principle of Target Protein Expression Led by p53 Pulsing

open access: yesFASEB BioAdvances, EarlyView.
The central dogma indicates the direction of gene expression pathways. Taking p53 pulsing as an example, I proved that the average fold changes in mRNA and target protein expression are the same, and the Hill‐type equation can describe such fold changes. This equation reveals the principle of target protein expression. Amplitude modulation is effective

The evolution of sensitive periods beyond early ontogeny: Bridging theory and data

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Sensitive periods, in which experiences have a large impact on phenotypic development, are most common early in ontogeny. Yet, they may also occur at later ontogenetic stages, such as adolescence.

Influence of temperature on host location and multisensory orientation in the parasitoid Pimpla turionellae (L.) (Hymenoptera) [PDF]

open access: yes, 2008
The ichneumonid wasp Pimpla turionellae (L.) (Hymenoptera) is a specialist parasitoid of lepidopteran pupae, and has to overcome the challenge of reduced chemical and visual cues as pupae are immobile, do not feed and do not emit excrements.

Spiroacetals and the rise of Campanula specialists: Receptor sensitivity to host‐specific floral scents

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Campanula flowers (Campanulaceae) are visited by generalist and specialist bees of different families. While generalists rely on common volatiles within the floral scent of Campanula, specialist Megachilidae mainly use unusual spiroacetals for host flower recognition ...

Do lifetime contest costs affect the evolution of assessment strategies? A meta‐analysis

open access: yesJournal of Animal Ecology, EarlyView.
Our meta‐analysis reveals unexpected patterns in the evolution of assessment strategies during animal contests. We show that self‐assessment dominates in high‐cost fights, challenging existing theories. This study provides novel insights into the link between fighting costs and behavioural evolution, with implications for understanding fitness ...
