"San Antonio Zoo Animals' Reactions to April 8 Solar Eclipse Caught on Video"

The San Antonio Zoo released video clips showing how animals reacted during the solar eclipse, with meerkats running through their habitat, whooping cranes "dancing," and flamingos clustering. The animals' activities, though not uncommon, were performed in a different context than usual, with the meerkats displaying evening activity patterns during totality. Zoos across the country were excited to study animals' behavior during the eclipse, as researchers have found that many animals display behaviors connected with an early dusk.

The Dark Secrets of Female Meerkat Infanticide Revealed

Female meerkats exhibit aggressive behavior towards rivals, including evicting them and killing their offspring. A recent study suggests that dominant female meerkats possess unique gene expression not found in lower-status individuals. These high-ranking females have higher levels of androgen, associated with aggressiveness, and show an upregulation of genes related to inflammatory response, indicating better immune function. This genetic advantage helps them maintain their dominant status and reproductive success, resulting in a significant skew in offspring distribution within meerkat social groups. The study highlights the importance of social status in regulating immune genes and reproductive competition among social animals.

Unveiling the Dark Side: The Hidden Motives of Female Meerkats

Dominant female meerkats exhibit a brutal behavior of killing female relatives and eating their offspring to maintain control of the mob. A new study suggests that these murderous matriarchs have a sex-specific signature of dominance that gives them super-immunity, resembling immunity genes seen in male baboons. Dominant female meerkats control up to 80% of breeding and have higher levels of cortisol and androgen hormones, as well as a higher body mass. They also show an increased response to inflammatory stimuli, indicating better preparedness to fight infections. The findings support the hypothesis that social status is dependent on the energy needed to achieve dominance and highlights the impact of social interactions on molecular processes in animals.

Meerkat deaths at Philadelphia Zoo linked to suspected poisoning.

All five meerkats at Philadelphia Zoo have died within a month, with officials suspecting that they may have accidentally consumed a toxic dye used to mark them. The dye, Nyanzol-D, is thought to be the culprit. A necropsy is pending, and the zoo is coordinating with the US Department of Agriculture and the Association of Zoos and Aquarium to identify the cause of the deaths. The zoo currently houses more than 1,900 animals.

Philadelphia Zoo's Meerkat Tragedy: Poisoning Suspected.

The Philadelphia Zoo is investigating the deaths of its five meerkats, which occurred within two weeks. The zoo suspects that the agricultural dye Nyanzol-D, used to differentiate some of the animals, may have caused a toxic reaction. The dye had been used on the meerkats before, and the zoo has now stopped using it. The zoo is working with the Association of Zoos and Aquariums and the US Department of Agriculture to determine the official cause of the animals' deaths, which could take weeks or months.

Mystery surrounds death of 5 meerkats at Philadelphia Zoo.

The Philadelphia Zoo is investigating the sudden deaths of all five meerkats, which occurred within weeks of each other. The zoo suspects that an animal dye used for decades might be the cause of their deaths. The meerkats were siblings and came to the zoo in 2013. The zoo has stopped using the dye on all animals out of caution and is working with regulatory bodies on the investigation. The zoo staff is devastated by the loss of the animals.
