Solitary, observer, parallel, and social object play in the bottlenose dolphin (Tursiops truncatus)

Many comparative studies have focused on the emergence of solitary and social play in early development, however, few consider observer and parallel forms of play. In this study, we analyzed approximately 21 h of video recordings and revealed a significant difference...

Personality in the longsnout seahorse, Hippocampus reidi Ginsburg, 1933: Are males shyer than females?

Individual responses, particularly based on personality, can have important consequences for individual fitness, based upon success in exploring new habitats, feeding on novel foods, and aggressiveness in competitive interactions. We conducted laboratory experiments to analyze individual responses to different artificial...

The effects of environmental enrichment and social isolation and their reversion on anxiety and fear conditioning

Animal models of fear and anxiety provide important insight into anxiety-related symptoms in humans. Environmental physical conditions and social contact influence behavior and brain plasticity particularly at early developmental stages and have long lasting effects reaching even adulthood. The potential...

Positive and negative emotions in dairy cows: Can ear postures be used as a measure?

Applying objective measures to assess the emotional states of animals is an important area of research and essential for improving animal welfare. In this study, we have built upon previous research to test whether ear postures can be used as...

Song practice as a rewarding form of play in songbirds

In adult songbirds, the primary functions of song are mate attraction and territory defense; yet, many songbirds sing at high rates as juveniles and outside these primary contexts as adults. Singing outside primary contexts is critical for song learning and...

The impact of changeability of enriched environment on exploration in rats

Although the positive effect of environmental enrichment on animals' cognitive capacities is well-known, it remains unclear what role changeability plays in this context. Our study aims to analyse the impact of environmental changeability on the level of exploration and the...

Return to home cage’ as a reward for maze learning in young and old genetically heterogeneous mice

Recent studies have shown that 'return to home cage' can serve as a reward for maze learning in adult male mice. The present study examined whether the same reward is an effective motivator of learning in young and old mice...

Returning to home cage serves as an effective reward for maze learning in rats

This study examined the effectiveness in rats of ‘returning to home cage' as a reward for learning a Lashley III maze. Rats could return to their home cage directly (Direct HC group) or they could be removed manually by an...

Particle motion and sound pressure in fish tanks: A behavioural exploration of acoustic sensitivity in the zebrafish

Underwater sound fields can be complex, both in open water and small tank environments. Here we measured 1) spatial variation in artificially elevated sound levels in a small fish tank for both particle motion and sound pressure. We confirmed that...

Executing specific foraging behaviours does not represent a general goal state of foraging in dry sows (Sus scrofa)

Intensively housed domestic pigs (Sus scrofa) have little opportunity to perform diverse foraging behaviour though they still seem strongly motivated to do so. Here, we investigated whether the execution of specific behaviours may in itself satisfy their foraging motivation. We...
