ANNUAL ACTIVITY OF THE NOBLE CRAYFISH (ASTACUS ASTACUS) IN THE ORLJAVA RIVER (CROATIA) [PDF]
Bulletin Français de la Pêche et de la Pisciculture, 2006 We studied the annual activity of the noble crayfish (Astacus astacus) at three sites along the Orljava River, in the continental part of Croatia, between August 2003 and September 2004. Each site represented the typical characteristics of the upper, middle and lower section of the river (5, 30 and 50 km from the spring, respectively).

Sex‐Specific Control and Incomplete Matings: Sperm Removal Behavior in a Bush Cricket Species
Ethology, Volume 132, Issue 3, Page 194-203, March 2026.In this study, we investigated which sex influences the duration of sperm removal behaviour (SRB) in the ornate bush cricket, Metaplastes ornatus. Female traits showed a weak effect on SRB duration, and lighter females mated more frequently. Frequent unsuccessful mating terminations shortened SRB indicating high level of sexual conflict.

Preventing the next invasion: Lessons from aquaculture for the safe expansion of insect farming
Journal of Applied Ecology, Volume 63, Issue 2, February 2026.We argue that preemptive risk assessments, species screening and transferable, adaptive regulatory frameworks developed for aquaculture offer a critical foundation for safeguarding against insect#x02010;driven invasions. Proactive governance that embeds these safeguards before large#x02010;scale expansion offers a rare opportunity to prevent invasion ...
