The inoculation fallacy: why early enrichment cannot compensate for poor adult environments

Early-life environmental enrichment (EE) is widely promoted as a route to building resilience and competence, yet these benefits rarely persist when adult environments lack opportunities for agency. Resilience and competence are behavioral properties of current reinforcement contingencies, not internal traits....

What is your tattoo ink telling you?

Tattooing traumatizes the skin, which can result in microbial infections with the severity ranging from minor to life-threating septicemia. Additionally, the metals in colored tattoo ink are known to cause dermal inflammation in some people. In the laboratory animal research...

Harm-benefit analysis may not be the best approach to ensure minimal harms and maximal benefits of animal research—Alternatives should be explored

Using animals in scientific research is commonly justified on the utilitarian basis that the benefits of scientific progress to human health and society exceed by far the harm inflicted on animals. In an attempt to ensure that this is indeed...

Too cute to kill? The need for objective measurements of quality of life

The recognition of animal suffering is influenced by cultural and societal prejudices and the cuteness of an animal leads to bias in the way it is treated. It is important to consider the animal’s behaviour and its environment—not just its...

Towards more compassionate wildlife research through the 3Rs principles: Moving from invasive to noninvasive methods

Research in ecology and wildlife biology remains crucial for increasing our knowledge and improving species management and conservation in the midst of the current biodiversity crisis. However, obtaining information on population status often involves invasive sampling of a certain number...

Where are we heading? Challenges in evidence-based severity assessment

Evidence-based severity assessment in laboratory animals is, apart from the ethical responsibility, imperative to generate reproducible, standardized and valid data. However, the path towards a valid study design determining the degree of pain, distress and suffering experienced by the animal...

A ten-stage protocol for assessing the welfare of individual non-captive wild animals: Free-roaming horses (Equus ferus caballus) as an example

Knowledge of the welfare status of wild animals is vital for informing debates about the ways in which we interact with wild animals and their habitats. Currently, there is no published information about how to scientifically assess the welfare of...

Defining and managing pain in stroke and traumatic brain injury research

Neurologic conditions such as stroke and traumatic brain injury are challenging conditions to study in humans. Animal models are necessary to uncover disease processes and develop novel therapies. When attempting to model these or other neurologic diseases, the accompanying anesthesia...

The natural behavior debate: Two conceptions of animal welfare

The performance of natural behavior is commonly used as a criterion in the determination of animal welfare. This is still true, despite many authors having demonstrated that it is not a necessary component of welfare – some natural behaviors may...

The power of a positive human–animal relationship for animal welfare

Domestic animals often seek and enjoy interacting with humans. Positive human–animal relationships can elicit positive emotions and other positive welfare outcomes. Nevertheless, our understanding of the underlying processes that govern the positive perception of humans by animals is incomplete. We...
