Podocnemis Expansa
The Arrau turtle (''Podocnemis expansa''), also known as the South American river turtle, giant South American turtle, giant Amazon River turtle, Arrau sideneck turtle, Amazon River turtle or simply the Arrau, is the largest of the side-neck turtles (Pleurodira) and the largest freshwater turtle in Latin America. The species primarily feeds on plant material and typically nests in large groups on beaches. Due to hunting of adults, collecting of their eggs, pollution, habitat loss, and dams, the Arrau turtle is seriously threatened. Range and habitat Arrau turtles are found in the Amazon, Orinoco and Essequibo basins in Brazil, Bolivia, Peru, Ecuador, Colombia, Venezuela and Guyana. On occasion, typically after floods, individuals turn up in Trinidad. They are found in deep rivers, ponds, freshwater lagoons and flooded forest in white-, black- and clear-water. Appearance Arrau turtles can reach up to in weight and the carapace length is up to . Most individuals are conside ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The IUCN Red List Of Threatened Species
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is an inventory of the global conservation status and extinction risk of biological species. A series of Regional Red Lists, which assess the risk of extinction to species within a political management unit, are also produced by countries and organizations. The goals of the Red List are to provide scientifically based information on the status of species and subspecies at a global level, to draw attention to the magnitude and importance of threatened biodiversity, to influence national and international policy and decision-making, and to provide information to guide actions to conserve biological diversity. Major species assessors include BirdLife International, the Institute of Zoology (the research division of the Zoological Society of London), the World Conservation Monitoring Centre, and many Specialist Groups within th ...

Turtle Farming
Turtle farming is the practice of raising turtles and tortoises of various species commercially. Raised animals are sold for use as gourmet food, traditional medicine ingredients, or as pets. Some farms also sell young animals to other farms, either as breeding stock, or more commonly to be raised there to a larger size for subsequent resale.Darrell Senneke, "" Turtle farms primarily raise freshwater turtles (primarily, Chinese softshell turtles as a food source and sliders and cooter turtles for the pet trade);Links from therefore, turtle farming is usually classified as aquaculture. However, some terrestrial tortoises (e.g. '' Cuora mouhotii'') are also raised on farms for the pet trade. Only three serious attempts are believed to have been made to farm sea turtles. Only one of them, in Cayman Islands, continues to operate. The one in Australia's Torres Strait Islands folded after a few years of operation, and the one in Réunion has been converted to a public aquarium (K� ...

CITES Appendix II
CITES (shorter acronym for the Convention on International Trade in Endangered Species of Wild Fauna and Flora, also known as the Washington Convention) is a multilateral treaty to protect endangered plants and animals from the threats of international trade. It was drafted as a result of a resolution adopted in 1963 at a meeting of members of the International Union for Conservation of Nature (IUCN). The convention was opened for signature in 1973 and CITES entered into force on 1 July 1975. Its aim is to ensure that international trade (import/export) in specimens of animals and plants included under CITES does not threaten the survival of the species in the wild. This is achieved via a system of permits and certificates. CITES affords varying degrees of protection to more than 40,900 species. , the Secretary-General of CITES is Ivonne Higuero. Background CITES is one of the largest and oldest conservation and sustainable use agreements in existence. There are three working ...

Traditional Medicine
Traditional medicine (also known as indigenous medicine or folk medicine) refers to the knowledge, skills, and practices rooted in the cultural beliefs of various societies, especially Indigenous groups, used for maintaining health and treating illness. In some Asia, Asian and Africa, African countries, up to 80% of people rely on traditional medicine for primary health care. Traditional medicine includes systems like Ayurveda, traditional Chinese medicine, and Unani medicine, Unani. The World Health Organization supports their integration, but warns of potential risks and calls for more research on their safety and effectiveness. The use of medicinal herbs spans over 5,000 years, beginning with ancient civilizations like the Sumer, Sumerians, Ancient Egypt, Egyptians, Indian people, Indians, and Chinese people, Chinese, evolving through Ancient Greece, Greek, Ancient Rome, Roman, Islam, Islamic, and Middle Ages, medieval European traditions, and continuing into Colonial histo ...

Critically Endangered
An IUCN Red List critically endangered (CR or sometimes CE) species is one that has been categorized by the International Union for Conservation of Nature as facing an extremely high risk of extinction in the wild. As of December 2023, of the 157,190 species currently on the IUCN Red List, 9,760 of those are listed as critically endangered, with 1,302 being possibly extinct and 67 possibly extinct in the wild. The IUCN Red List provides the public with information regarding the conservation status of animal, fungi, and plant species. It divides various species into seven different categories of conservation that are based on habitat range, population size, habitat, threats, etc. Each category represents a different level of global extinction risk. Species that are considered to be critically endangered are placed within the "Threatened" category. As the IUCN Red List does not consider a species extinct until extensive targeted surveys have been conducted, species that a ...

IUCN Species Survival Commission
The IUCN Species Survival Commission (IUCN SSC) is one of the six commissions of the International Union for Conservation of Nature (IUCN). The Species Survival Commission, the largest of the IUCN's six commissions, is a science-driven network consisting of 9,000 volunteer experts working in more than 160 Specialist Groups, including 17 invertebrate groups, Red List Authorities, and Task Forces. The IUCN Species Strategic Plan outlines conservation priorities, with the current plan covering the period from 2021 to 2025. Since 2016, Jon Paul Rodríguez is the chair of the commission. Specialist Groups SSC Specialist Groups are primarily taxon-specific volunteer organizations made up mostly of research biologists and natural historians. Some groups focus on conservation issues specific to certain plants, animals, and fungi, while others work on broader goals like species reintroduction into former habitats, addressing climate change, wildlife health, and promoting sustainable us ...

Temperature-dependent Sex Determination
Temperature-dependent sex determination (TSD) is a type of environmental sex determination in which the temperatures experienced during embryonic/larval development determine the sex of the offspring. It is observed in reptiles and teleost fish, with some reports of it occurring in species of shrimp. TSD differs from the chromosomal sex-determination systems common among vertebrates. It is the most studied type of environmental sex determination (ESD). Some other conditions, e.g. density, pH, and environmental background color, are also observed to alter sex ratio, which could be classified either as temperature-dependent sex determination or temperature-dependent sex differentiation, depending on the involved mechanisms. As sex-determining mechanisms, TSD and genetic sex determination (GSD) should be considered in an equivalent manner, which can lead to reconsidering the status of fish species that are claimed to have TSD when submitted to extreme temperatures instead of the temp ...
