Thirty Years of the Biology of Spermatozoa: The Rise and Future of an Evolutionary Paradigm

open access: yesEcology and Evolution, Volume 16, Issue 1, January 2026.
A sperm bundle taken from the seminal vescicles of the dung beetle, Onthophagus taurus. Image credit: Leigh W. Simmons. ABSTRACT In the early 1970s, Geoff Parker recognised that because females frequently mate with multiple males, competition for fertilizations will impose significant sexual selection on males and their ejaculates.

Partial Characterization of Digestive Proteases in the Common Snook Centropomus undecimalis

open access: yesInternational Journal of Biology, 2016
<p class="1Body">Common snook (<em>Centropomus undecimalis</em>) is a marine species with high aquaculture potential; although its digestive physiology is still unknown and knowledge of that could allow the development of a balanced feed for commercial culture of this fish. The objective of this study was to partially characterize the

The Interplay of Biotic and Abiotic Factors in Shaping Genetic Variation at 6Pgdh in the Bulb Mite

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
We used experimental evolution to track changes in 6Pgdh allele frequencies in bulb mites over 13 generations under different temperatures and sexual selection intensities. Our results show that the F allele increases in frequency only at low temperatures under strong sexual selection, indicating that the maintenance of genetic variation in this system

Reality Check on Formal Methods in Industry: A Study of Verum Dezyne

open access: yesJournal of Software: Evolution and Process, Volume 37, Issue 12, December 2025.
ABSTRACT Many of the classical questions reflecting the actionable use of formal methods in the software industry—“do they scale?” or “are they easily integrated?”—remain without a definitive answer, with many potentially adoptable formal notations being exploited in industry, but in a rather stove‐piped and siloed fashion, and with rather few ...
