Preventing the next invasion: Lessons from aquaculture for the safe expansion of insect farming
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 ...

Wild boar feeding habits before versus after wolf recolonization
By analyzing wild boar diet before and after wolf recolonization in a Mediterranean coastal area, we evaluated whether the return of wolves facilitated feeding on deer carcasses by wild boar. While deer hair was never reported in samples of wild boar feces in 1991–1994, we found it in c.

Crayfish invading Europe: the case study ofProcambarus clarkii [PDF]
The red swamp crayfish, Procambarus clarkii, native to northeastern Mexico and southcentral USA, is today the dominant macroinvertebrate in several European countries. While the first introduction of this species into Spain is well-documented, little is known about its pathways of invasion and the reason for its rapid spread in several European ...

The aim of this study was to evaluate the effect of acoustic stimulus on the behavioural and biochemical responses of two species of crayfish, Cherax destructor and Cherax quadricarinatus. Our results showed that exposure to noise significantly affects in both species motility parameters, agonistic interactions and acoustic signals emitted. In terms of

Command Interneurons in the Crayfish Central Nervous System [PDF]
The motor effects evoked by stimulation of each of eight command fibres in the circumoesophageal commissures of the crayfish are described. The fibres obtained appeared to have widespread connexions in all or most of the lower ganglia. For certain fibres

Applicazione di un protocollo di immuno-stimolazione su individui di Pracambarus clarkii mirato alla produzione di peptidi con attività biologica [PDF]
Uno dei principali problemi inerenti l’identificazione e l’analisi di nuovi peptidi naturali di origine marina è la disponibilità in termini quantitativi del materiale bioattivo (Cragg et al., 1997).
