When dogs interact with humans, they often show appropriate reactions to human intentional action. But it is unclear from these everyday observations whether the dogs simply respond to the action outcomes or whether they are able to discriminate between
Animals were euthanized by CO2-asphyxiation on the same day of capture, then immediately processed for retinal tissue analysis or preservation. All experimentas were approved by and carried out in accordance with the regulations of The Purdue Institutional Animal Care and Use Committee (protocols ...
Scientific American is the essential guide to the most awe-inspiring advances in science and technology, explaining how they change our understanding of the world and shape our lives.
The resulting increase in scientific knowledge on the abilities of animals will hopefully help to change people's perceptions of animals and will have varying implications for practices and industries. In this study we have reviewed articles published from 1990 to 2012 and identified the taxa being ...
This introduction places these articles into the broader contexts of the literature in these three domains of interest. Across the world, urbanization, migration, armed conflict, epidemics, and famine disrupt families. Add poverty, abuse, neglect, and parental incapacity due to and mental health ...
Some examples of effects of RFR on male fertility factors in studies with experimental animals at SARs below 4 W/kg include: a decrease in sperm count and an increase in ROS in rats exposed to mobile phone frequencies 2 hr./day, for 35 days (SAR = 0.9 W/kg) [59]; inc...
Information about the geological timeframe during which animals radiated into their major subclades is crucial to understanding early animal ecology and evolution. Unfortunately, the pre-Cambrian fossil record is sparse and its interpretation controversi
We rather argue that representation of own actions, one form of representation of the self, has evolved in this species, that is phylogenetically distant from humans, and may have evolved in a range of other social animals too. We acknowledge that this study was conducted on a relatively ...
