Tayassu — LLMpedia

Contents

Tayassu is a genus of New World peccaries native to the Americas, historically important in Neotropical ecosystems and human cultures. Members of this genus have been studied across disciplines by researchers from institutions such as Smithsonian Institution, Natural History Museum, London, American Museum of Natural History, University of California, Berkeley, and National Autonomous University of Mexico. Their fossil record and modern ecology connect to research by groups including Paleontological Society, Society of Vertebrate Paleontology, International Union for Conservation of Nature, World Wildlife Fund, and regional agencies like CONABIO and Instituto Nacional de Pesquisas da Amazônia.

Taxonomy and evolution

Tayassu taxonomy has been treated in revisions by taxonomists affiliated with Linnaeus Museum-style traditions and modern molecular labs at Harvard University, Stanford University, University of Oxford, University of Cambridge, and Max Planck Society units. Early systematic work referenced comparative collections at Royal Ontario Museum, Field Museum of Natural History, and Museo Nacional de Antropología; later phylogenetic analyses used DNA from samples processed in facilities such as Sanger Institute and Broad Institute. Paleontological context for Tayassu involves Pliocene and Pleistocene faunas studied in formations associated with La Brea Tar Pits, Santa Fe Formation, Chiapas Basin, and Amazon Basin deposits, and fossils cataloged at American Museum of Natural History and Museo de La Plata. Evolutionary scenarios integrate evidence from studies of convergent traits in Sus scrofa comparisons, biogeographic models by Ernst Mayr-inspired frameworks, and cladistic matrices used by researchers at University of Michigan and Smithsonian Institution.

Members of the genus display compact, robust morphology documented in anatomical studies from laboratories at Johns Hopkins University, University of Chicago, and University of Wisconsin–Madison. Skull morphology and dentition comparisons have been published in journals affiliated with Royal Society and Proceedings of the National Academy of Sciences. External traits—coarse pelage, fused toes, and short limbs—are often compared in field guides by Audubon Society, National Geographic Society, Encyclopædia Britannica, Inc. and regional manuals from Instituto de Biología UNAM. Morphometric datasets held by Global Biodiversity Information Facility, VertNet, and GBIF reflect measurements standardized by committees at International Commission on Zoological Nomenclature. Comparative morphology discussions reference specimens examined at Natural History Museum, London, Museo Argentino de Ciencias Naturales, and Museo Nacional de Historia Natural, Chile.

Geographic occurrence maps in atlases produced by IUCN Red List, BirdLife International (for comparative range methods), CONABIO, and Instituto Nacional de Pesquisas da Amazônia show Tayassu across Neotropical regions studied in projects with Pan American Health Organization and regional conservation NGOs such as Rainforest Alliance and Conservation International. Habitats discussed in fieldwork reports often reference ecosystems cataloged by United Nations Environment Programme, Ramsar Convention assessments, and national parks like Yasuní National Park, Calakmul Biosphere Reserve, Pantanal Matogrossense National Park, and Sierra de San Pedro Mártir National Park. Range shifts have been modeled using climate scenarios from Intergovernmental Panel on Climate Change and land-use analyses by Food and Agriculture Organization teams.

Behavioral ecology literature on Tayassu includes studies by researchers associated with University of Florida, University of Texas at Austin, Arizona State University, and international collaborators from Universidad de Los Andes and Universidad de Costa Rica. Social structure, foraging, and diel activity patterns are compared to work on ungulates published in outlets tied to Ecological Society of America and Journal of Mammalogy committees. Predator-prey interactions reference predators cataloged in regional faunal lists such as Panthera onca research by Panthera and carnivore studies at Wildlife Conservation Society, while seed dispersal roles link to publications involving Royal Botanic Gardens, Kew and Missouri Botanical Garden. Disease ecology integrates surveillance data from Centers for Disease Control and Prevention, World Organisation for Animal Health, and regional veterinary services.

Reproductive biology findings derive from captive and wild studies reported by institutions including Smithsonian Conservation Biology Institute, San Diego Zoo Global, Bronx Zoo, and university veterinary programs at Cornell University and University of Pennsylvania School of Veterinary Medicine. Life-history parameters—litter size, gestation, juvenile development—are discussed in conservation plans prepared by IUCN Species Survival Commission and regional wildlife agencies such as Secretaría de Medio Ambiente y Recursos Naturales and Instituto Brasileiro do Meio Ambiente e dos Recursos Naturais Renováveis. Demographic modeling often employs techniques from groups like Population Association of America and statistical frameworks from R Project for Statistical Computing.

Conservation assessments produced by IUCN Red List, national red lists such as Lista Nacional de Especies Protegidas (Mexico), and NGOs including World Wildlife Fund, Conservation International, and Wildlife Conservation Society evaluate threats like habitat loss documented in reports by Food and Agriculture Organization, United Nations Development Programme, and Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services. Hunting pressure, land conversion, and disease spillover are focal concerns in management strategies coordinated with agencies including U.S. Fish and Wildlife Service, Instituto Nacional de Pesquisas da Amazônia, and regional ministries of environment. Conservation actions reference protected areas such as Yasuní National Park, Calakmul Biosphere Reserve, and community initiatives supported by The Nature Conservancy and indigenous organizations like Confederación de Nacionalidades Indígenas del Ecuador.
