Did amphibians give rise to reptiles?

What are some examples of reptiles in biology?

Reptiles have an extremely diverse evolutionary history that has led to biological successes, such as dinosaurs, pterosaurs, plesiosaurs, mosasaurs, and ichthyosaurs . This section does not cite any sources. Please help improve this section by adding citations to reliable sources.

Is the global distribution of tetrapods relevant for Reptile Conservation?

In contrast, the global distributions of reptiles, representing a third of terrestrial vertebrate d … The global distribution of tetrapods reveals a need for targeted reptile conservation Nat Ecol Evol. 2017 Nov;1(11):1677-1682.doi: 10.1038/s41559-017-0332-2.

Why aren’t reptiles included in global conservation-prioritization analyses?

Because global assessments have been lacking, reptiles have been omitted from conservation-prioritization analyses that encompass other tetrapods 4, 5, 6, 7. Reptiles are unusually diverse in arid regions, suggesting that they may have different conservation needs 6.

Are nature reserves effective in conserving threatened terrestrial vertebrates in China?

In this study, we developed a distribution database of threatened terrestrial vertebrates in China, then explored the patterns of the threatened terrestrial vertebrates and evaluated the effectiveness of current nature reserves in terms of their conservation, further identified the conservation priorities for these species in China.

What is the Global Reptile assessment?

The Global Reptile Assessment (GRA) is currently carrying out assessments via regional workshops, which bring together species experts to discuss extinction risk and conservation priorities.

Are reptiles threatened with extinction?

Global assessments reveal that, among tetrapods, 40.7% of amphibians, 25.4% of mammals and 13.6% of birds are threatened with extinction 3. Because global assessments have been lacking, reptiles have been omitted from conservation-prioritization analyses that encompass other tetrapods 4, 5, 6, 7.

How important is the global distribution of reptiles to global biodiversity?

In contrast, the global distributions of reptiles, representing a third of terrestrial vertebrate diversity, have been unavailable. This prevented the incorporation of reptiles into conservation planning and biased our understanding of the underlying processes governing global vertebrate biodiversity.

What can I do to help reptiles?

Small sites can be valuable for reptiles. Gardens, allotments and school grounds can all be managed to benefit reptiles. Connections between these area with nearby ‘countryside’ or with other gardens are important for encouraging colonisation and for sustaining populations.

Are reptiles more threatened than other vertebrates?

We’ve already been able to compare our results to those for other vertebrate groups on the IUCN Red List in a separate study, and demonstrate that reptiles as a group are more threatened than birds, but less than mammals and amphibians,” said Dr Bruce Young, Chief Zoologist and Senior Conservation Scientist at NatureServe.

Is the current nature reserve network sufficient to protect threatened species?

The current nature reserve network is inadequate to capture the threatened vertebrate species. The nature reserves were found to cover 30.47% of the hotspots and 38.65% of the ranges of these species on average, with quite a few conservation hotspot and species gaps.

How do wetland reserves contribute to the conservation of wildlife in China?

Due to the construction of wetland reserves in China, the contribution of wetland NNRs and NWPs to the conservation of wildlife has improved steadily, thereby promoting the protection and management of wildlife and their habitats throughout the country.

What is China’s role in biodiversity conservation?

China, as one of the world’s megadiverse countries, plays a critical role in global biodiversity conservation. The upcoming 15th Conference of Parties (COP15) for Convention on Biological Diversity (CBD) serves as an opportunity for China to make ambitious but pragmatic commitments to elevate its wildlife conservation and management activities.

Is the green vine snake threatened with extinction?

The green vine snake (Ahaetulla nasuta ) is among the world’s reptiles that face extinction. Nearly one in five of the world’s estimated 10,000 species of lizards, snakes, turtles, crocodiles and other reptiles are threatened with extinction, according to a study conducted by 200 experts.

Are we doing enough to protect reptiles?

Moreover, existing protected areas, sites of biodiversity significance and global conservation schemes represent birds and mammals better than reptiles. We show that additional conservation actions are needed to effectively protect reptiles, particularly lizards and turtles.

Which animals are best surrogates for Reptile Conservation?

Birds, mammals and amphibians are unexpectedly good surrogates for the conservation of reptiles, although threatened reptiles with the smallest ranges tend to be isolated from other threatened tetrapods.

What percentage of China’s land is protected by nature reserves?

China’s nature reserves encompass 15.1% of the country’s land surface. They capture 17.9% and 16.4% of the entire habitat area for threatened mammals and birds, but only 13.1% for plants, 10.0% for amphibians, and 8.5% for reptiles.

How effective is the protection of wildlife in China?

At present, the network of protected wetlands in China preserves most of the national key protected and endangered wild animals, and the overall effectiveness of the protection of wildlife is relatively high.

How effective are wetland National Nature Reserves and national wetland parks?

The results showed that a wetland National Nature Reserve and National Wetland Park network have been constructed in China and they have gradually increased in size, where the wildlife conservation efficacy is high and the proportion protected has increased.

Does conservation beyond the protected area network improve species and habitat representation?

Conservation beyond the existing protected area network is required to improve species and habitat representation in a global biodiversity hotspot We evaluated the representation of wildlife and forest types within protected areas. Current protected area network underrepresented wildlife species and forest types.

How effective are nature reserves in protecting biodiversity?

Habitat degradation and loss threaten the survival of many species, especially vertebrates. The establishment of nature reserves is an efficient approach to protect biodiversity. However, fulfilling conservation targets depends largely on the effectiveness of these nature reserves in capturing the targeted species.

What is the primary cause of loss of biodiversity in China?

While the primary current cause of loss in diversity of species, populations and ecosystems in China is over-exploitation, in the U.S. it is habitat destruction.

What is the Asian government doing to protect biodiversity?

Policies—and actions—by Asian governments, civil society and the private sector are fundamental to biodiversity conservation, viable ecosystems, sustainable resource utilisation and rebuilding natural capital. Current policies are predominately ‘command 3

How does China’s Biodiversity Conservation compare to the United States?

This essay analyzes the contrasting approaches taken to biodiversity conservation by the world’s third largest nation-state, China, as compared to the fourth, the United States. While the primary current cause of loss in diversity of species, populations and ecosystems in China is over-exploitation, in the U.S. it is habitat destruction.

What is China’s “ecological civilization?

“Ecological civilization” was written into China’s constitution as the ideological framework for the country’s sustainable development. The national and provincial social and economic development five-year plans also include ecological conservation as a key element.

What has the center done to protect amphibians and reptiles?

The Center outdid itself in protecting these amazing creatures in 2012, when we made the biggest-ever move to protect amphibians and reptiles in the United States, filing a mega-petition requesting Endangered Species Action protection for 53 amphibians and reptiles in 45 states.
