Exposure to an enriched environment exerts anxiolytic effects in Sardinian alcohol-preferring rats

Exposure to an enriched environment (EE) has been reported to generate multiple beneficial effects in rodents, including – among the many – amelioration of anxiety-related behaviors. The present study investigated whether living in an EE produced anxiolytic effects also in...

A new tool for quantifying mouse facial expressions

Facial expressions are an increasingly used tool to assess emotional experience and affective state during experimental procedures in animal models. Previous studies have successfully related specific facial features with different positive and negative valence situations, most notably in relation to...

Preterm rat survival is enhanced by gestational environmental enrichment

Throughout the last decade, the estimated global human preterm birth rate was 10.6 %, with higher rates in Asia, South America, and Africa. Preterm individuals, even in adulthood, are more likely to develop cardiorespiratory, renal, and metabolic disorders. On the...

Reassessing cow comfort measures on Canadian dairy farms after a recommendation of improvements

In a previous study (Assessment 1), an on-farm assessment tool was used to establish a standard across 60 Quebec dairy farms using animal-, stall-, and management-based measures of cow comfort. The objective of the present follow-up study (Assessment 2) was...

Different housing conditions for zebrafish: What are the effects?

Zebrafish is a popular experimental model in several research areas but little is known about the effects of using different strains or housing conditions. Poor control of genetic background and housing conditions could affect experimental results and data reproducibility. Here...

Atypical play experiences in the juvenile period has an impact on the development of the medial prefrontal cortex in both male and female rats

In rats reared without play, or with limited access to play during the juvenile period, the dendrites of pyramidal neurons of the medial prefrontal cortex (mPFC) exhibit more branching than rats reared with more typical levels of play. This suggests...

Initial compatibility during a “Speed-Dating” test predicts postpairing affiliation in titi monkeys (Plecturocebus cupreus)

Behavioral compatibility plays a critical role in shaping how potential mates interact with and evaluate each other and whether they choose to pursue a relationship. Compatibility is especially important for mate choice and relationship quality in pair-bonding species that form...

Urinary cytokine measurements do not reflect surgery-induced inflammation in rhesus macaques

Measurement of the health and disease status of free-ranging primates is often limited by a lack of available biomarkers of immune activation and inflammation that can be applied noninvasively via the measurement of urine or fecal samples. Here, we evaluate...

Do bumble bees play?

A variety of animals have been found to interact with and manipulate inanimate objects ‘just for fun', that is, to play. Most clear examples of object play come from mammals and birds. However, whether insects interact with inanimate objects as...

Residency and swimming behavior of Acanthopagrus schlegelii, Trachinotus blochii, and Acanthopagrus latus in relation to artificial reef models in a captivity experiment

Global capture fisheries production has declined rapidly over the past decades because of the growing demand for fisheries resources. To restore fisheries resources, artificial reefs (ARs) are deployed on the seafloor to provide new habitats for marine life. However, the...
