Virtual fencing systems have emerged as a promising technology for managing the distribution of livestock in extensive grazing environments. This study provides comprehensive documentation of the learning process involving two conditional behavioral mechanisms and the documentation of efficient, effective, and safe animal training for virtual fence applications on nursing Brangus cows. Two hypotheses were examined: (1) animals would learn to avoid restricted zones by increasing their use of containment zones within a virtual fence polygon, and (2) animals would progressively receive fewer audio-electric cues over time and increasingly rely on auditory cues for behavioral modification. Data from GPS coordinates, behavioral metrics derived from the collar data, and cueing events were analyzed to evaluate these hypotheses. The results supported hypothesis 1, revealing that virtual fence activation significantly increased the time spent in containment zones and reduced time in restricted zones compared to when the virtual fence was deactivated. Concurrently, behavioral metrics mirrored these findings, with cows adjusting their daily travel distances, exploration area, and cumulative activity counts in response to the allocation of areas with different virtual fence configurations. Hypothesis 2 was also supported by the results, with a decrease in cueing events over time and increased reliance with animals on audio cueing to avert receiving the mild electric pulse. These outcomes underscore the rapid learning capabilities of groups of nursing cows in responding to virtual fence boundaries.

COVID-19 lockdowns in early 2020 reduced human mobility, providing an opportunity to disentangle its effectson animals from those of landscape modifications. Using GPS data, we compared movements and roadavoidance of 2300 terrestrial mammals (43 species) during the lockdowns to the same period in 2019.Individual responses were variable with no change in average movements or road avoidance behavior, likely dueto variable lockdown conditions. However, under strict lockdowns 10-day 95th percentile displacementsincreased by 73%, suggesting increased landscape permeability. Animals’1-hour 95th percentiledisplacements declined by 12% and animals were 36% closer to roads in areas of high human footprint,indicating reduced avoidance during lockdowns. Overall, lockdowns rapidly altered some spatial behaviors,highlighting variable but substantial impacts of human mobility on wildlife worldwide.

Landbruket er en særdeles viktig bidragsyter til norsk beredskap. Mat og innsatsfaktorer til matproduksjon utgjør våpen i geopolitiske konflikter. Matsikkerhet er derfor avgjørende for stabile og trygge samfunn, og for å forhindre konflikter. Betydningen av dette er bragt til nye høyder de siste årene gjennom krig, pandemi, klimakrise og uår. Drøvtyggerne er fermenteringseksperter som omdanner ufordøyelige beitevekster til energi og fullverdig protein for mennesker. Ressursgrunnlaget i Norge tilsier at det bør satses på disse husdyra - ikke minst i Nord-Norge. Dette er viktig for å øke norsk selvforsyning og matsikkerhet.
