Introduction to the Axolotl and Its Current Status
The University National Autonomous of Mexico (UNAM) has reported the discovery of the Axolotl of the Highlands (Ambystoma velasci) in Querétaro, a species not sighted for 15 years. This finding is of great importance as the Axolotl is classified as endangered due to habitat degradation, urbanization, and water pollution.
The Discovery: A Persevering Effort
Led by researcher Diego de Jesús Chaparro Herrera and bilogist Julio César Parra Escobar, the team’s perseverance paid off when they located a population of Axolotls in an artificial lake (bordo) near Amealco de Bonfil. This lake serves as a refuge, protected from human interference and thus safeguarding the Axolotls along with their surrounding environment, including water resources and forests.
The Significance of the Finding
The team found approximately 50 Axolotls, suggesting that this species could serve as an umbrella species, warranting public resources for its protection by local, state, and federal governments. The researchers aim to designate the area as a Natural Protected Zone to preserve not only the Axolotl but also other species inhabiting the region.
Conservation Efforts and Challenges
The research team conducted a water quality analysis, examining parameters such as dissolved oxygen percentages, acidity, conductivity, temperature, suspended and dissolved solids, bacteria counts, and the number of Axolotls found in the water system.
A census is being carried out, documenting each Axolotl’s age, sex, health status, weight, and measurements. Researchers identify individual Axolotls by unique markings on their left side.
The Axolotl’s habitat spans temperate forests, pastures, and cold-water streams in central Mexico, including the states of Puebla, Hidalgo, Querétaro, Guanajuato, Morelos, and Veracruz. Historically, it was only found in restricted areas of Mexico State and Hidalgo but has recently been spotted as far north as Chihuahua and Durango.
Addressing Water Pollution
Chaparro Herrera emphasized the need to raise awareness about the Axolotl’s importance, as there is a lack of focus on this species. He highlighted that water bodies where Axolotls were previously reported have excessive nutrient, ammonia, phosphate, and nitrogen concentrations, along with harmful bacteria levels.
These pollutants accumulate in agricultural areas during rainwater percolation, contaminating the water sources that Axolotls rely on. To tackle this issue, it is crucial to decrease contamination levels in Amealco, requiring collaboration between authorities and farmers to provide alternative cultivation and irrigation methods.
Key Questions and Answers
- What is the Axolotl of the Highlands? The Axolotl of the Highlands, or Ambystoma velasci, is an endangered salamander species native to central Mexico.
- Why is this discovery significant? This discovery is crucial as it confirms the Axolotl’s presence in Querétaro after a 15-year absence, providing hope for its conservation.
- What challenges does the Axolotl face? The Axolotl is threatened by habitat loss, urbanization, and water pollution.
- What are the researchers planning to do? Researchers aim to conduct a four-year study, potentially implementing conservation actions similar to those in Xochimilco to protect Axolotls and their ecosystem.
- What is the impact of water pollution on Axolotls? Water pollution from agricultural runoff has led to excessive nutrient and bacteria levels in Axolotl habitats, threatening their survival.
