How Many More Brazilian Environmental Defenders Have to Perish Before We Act? President Lula\u27s Challenge to Protect Environmental Quilombola Defenders

The Global South has been historically marginalized and continues to suffer from systemic oppression, impeding the realization of their human rights. Afro-descendants and other minority populations in the Global South live in disproportionately environmentally unsafe conditions and are disproportionately more vulnerable to climate change and environmental harm. One of those populations are Quilombolas. Quilombolas are Brazilian Afro-descendant communities who continue to fight to protect their community rights to ancestral lands, natural resources, and survival as a people. The Brazilian government under former Brazilian President Bolsonaro engaged in a persistent and systematic campaign to target, attack, and kill defenders, including Quilombola defenders, who sought to protect the environment and human rights. His government engaged in the systematic deforestation and extraction of natural resources in the Amazon. It is up to Brazil’s re-elected President Luiz Inácio Lula da Silva and his new administration to ensure that the Amazon is protected, and that human rights defenders, including Quilombola defenders, are protected and are able to have justice and accountability for their human rights violations. We must hold the Brazilian state and private actors responsible for human rights violations through the existing rights-based framework through the newly ratified Regional Agreement on Access to Information, Public Participation and Justice in Environmental Matters in Latin America and the Caribbean (“Escazú Agreement”) and the Esperanza Protocol

Time to Wake Up! Pushing the Boundaries in the Americas to Protect the Most Vulnerable, 39 UCLA J. Envtl. L. & Pol\u27y 123 (2021)

It is time to wake up and push for the protection of the environment and against climate change. Vulnerable communities around the world are living in polluted, highly toxic, and unsustainable environments. It is time to protect them through a human rights-based framework. This article proposes that the Inter-American right to a healthy environment provides the possibility of protecting the human rights of the most vulnerable in the Americas by providing a rights-based framework for them to vindicate their environmental human rights. This article focuses on vulnerable populations who have been historically marginalized and discriminated against and/or who are reliant on the natural resources in their environments. This article posits that the greening of human rights, which is the traditional approach to the protection of environmental human rights, is not sufficient to protect vulnerable non-indigenous populations without protection. It is for this reason that we, as a society, must think creatively about environmental human rights advocacy, and create a system that moves forward the development of the right to a healthy environment. We must hold States responsible for their actions and for their support of corporations who exploit natural resources and populations living in them. If we know that so much human suffering is already happening due to environmental harm and climate change, why are we continuing on this path

Discovery of Endangered Mexican Blindcat, Prietella phreatophila, in Texas: Implications for International Groundwater Management and Evolution of the Regional Karst Aquifer Biota

Paper presented July 15, 2017 at the annual Joint Meeting of Ichthyologists and Herpetologists in Austin, Texas, USA (http://conferences.k-state.edu/JMIH-Austin-2017/). The oral presentation of this content mentioned questions about the taxonomy and phylogenetic position of Prietella lundbergi and the only specimens attributed to P. lundbergi apart from the holotype. Since the presentation, we obtained high resolution CT scans of both the holotype and a specimen (TNHC 25767) from Cueva del Nacimiento del Río Frio, not far north of the type locality. The anatomy revealed in those CT scans suggests that these specimens represent a single species, and that P. lundbergi is only remotely related to Prietella phreatophila, which would be consistent with results of Wilcox, T.P., F.J. Garcı́a de León, Dean A. Hendrickson, and D.M. Hillis. 2004. “Convergence among Cave Catfishes: Long-Branch Attraction and a Bayesian Relative Rates Test.” Molecular Phylogenetics and Evolution 31 (3): 1101–13. doi:10.1016/j.ympev.2003.11.006). Thus, further research is in progress by Hendrickson, Lundberg, Luckenbill and Arce that may result in taxonomic revision removing P. lundbergi from Prietella.Mexican blindcat, Prietella phreatophila, described in 1954 from a cave system near the town of Múzquiz in central Coahuila state, and considered a Mexican endemic, was listed by the U.S. Fish and Wildlife Service as a foreign endangered species (protected "wherever found") in 1970. Explorations in the 1990s discovered many new localities extending nearly to the international border, and in 2016 the species was discovered in Amistad National Recreation Area (ANRA) in Texas, just north of the international border near Del Rio. Not only does the discovery support the aquifer of this fish being an internationally shared resource, but the stygobitic invertebrate biota found with the fish indicates a potentially large extent of the aquifer, and thus possibly the fish, in Texas. Invertebrate faunal connections (historic or current) extend from the Amistad Lake area of the new occurrence west into the Trans-Pecos region and east into the Edwards Aquifer of central Texas. We explore implications of this for both water management and evolutionary history of this and other blind ictalurids, and suggest that population genetic studies of both stygobitic fishes and invertebrates could help hydrogeologists better define often difficult to map aquifer extents and interconnections. While NPS is continuing to support the cave explorations of ANRA that produced the Texas discovery, we propose a broader bi-national sampling effort for both the fish and invertebrates extending well beyond the current known distribution of P. phreatophila. We also pointed out questions about phylogenetic relatedness of P. phreatophila and P. lundbergi further south, as well as the possibility of a monophyletic clade of blindcats, including those of the Edwards Aquifer, Satan and Trogloglanis. If substantiated, that evolutionary history would imply broader historic inter-aquifer connections ranging from the San Antonio area as far south as southernmost Tamaulipas. Finally, we report establishment of a small captive population of Prietella phreatophila at San Antonio Zoo for research and possibly eventual conservation applications.U.S. National Park Service; San Antonio Zoo; University of Texas at Austin College of Natural Sciences and Department of Integrative BiologyIntegrative Biolog

Discovery of the Mexican Blindcat, Prietella phreatophila, in the U.S., and an update on its rangewide conservation status

presented at the 2017 meeting of the Texas Academy of Science at Mary Hardin Baylor University, Belton, TexasMexican blindcat, Prietella phreatophila, was described in 1954 from a single locality in Northern Coahuila, México. Long listed as endangered by the Mexican federal government, it was listed by the U.S. Fish and Wildlife Service as a foreign endangered species in 1970, and the most recent (1996) update of its assessment for the IUCN Red List considers it endangered as well. Explorations in the late 1990s discovered many new localities extending nearly to the international border, and a captive population established provided insights into the species’ basic biology and behavior. In 2016 the species was discovered in a cave in the Amistad National Recreation Area (ANRA), just north of the Río Grande in Texas. The 1970 listing instantly gave the TX population full protection under the U.S. Endangered Species Act. The species’ subterranean and mostly inaccessible habitat endows it with extremely low detectability and its actual range is likely broader than physical sampling of specimens has revealed. We review all prior and new knowledge of the species and its habitat to provide an updated international reassessment of its overall conservation status and threats, which most notably include aquifer depletion and contamination in both the Mexican and U.S. portions of its known range. A live captive population of two specimens collected in 1997 in Coahuila and one Texas specimen is now at the San Antonio Zoo, we are working with NPS to further explore ANRA caves and hope eventually to return to Coahuila to more fully update the species’ conservation status.Integrative Biolog
