Rothschild's porcupine


Rothschild's porcupine, "Coendou rothschildi", is a species of rodent in the family Erethizontidae. It is usually considered endemic to Panama. A population in western Ecuador belongs either to this species or to "Coendou bicolor". Because of the confusion over its taxonomic status and because its ecology is little known, the IUCN has listed its conservation status as "data deficient". "Mammal Species of the World" treats "Coendou rothschildi" as a valid species endemic to Panama but states that it is possibly a subspecies

Due to its adaptability to a wide range of habitats and food types, the Indian crested porcupine is listed by the IUCN as Least Concern as of 2008. Populations are stable and not severely fragmented, and while population status varies across its range, in many places it is common enough to be considered a pest.

The African brush-tailed porcupine ("Atherurus africanus") is a species of rat-like Old World porcupine, indigenous to a broad belt of Africa ranging from Guinea on the west coast to Kenya on the east. This is a common species with a very wide range, and despite being used extensively for bushmeat, the International Union for Conservation of Nature has rated its conservation status as being of "least concern". The brush-tailed porcupine reaches 40 to 50 cm in length, not counting the tail.

Population numbers, trends and species' conservation status can be found at the lists of organisms by population. The conservation status of a species indicates the likelihood that it will become extinct. Many factors are considered when assessing the status of a species; e.g., such statistics as the number remaining, the overall increase or decrease in the population over time, breeding success rates, or known threats.

The North American porcupine has a long gestation period relative to other rodents. The female's pregnancy lasts for 202 days. By contrast, the North American beaver, which is comparable in size, has a gestation period of 128 days. The eastern grey squirrel ("Sciurus carolinensis") has a gestation period of just 44 days.

The 2013 assessment by the International Union for Conservation of Nature (IUCN) on their IUCN redlist assigns a status of species of least concern. It notes the species has become less common and locally extinct and the population trend is declining due

Lollipop catshark


. Reproduction is aplacental viviparous, with females retaining egg cases internally two at a time until they hatch. There is no fishery interest in this species, and the International Union for Conservation of Nature (IUCN) lacks sufficient information to assess its conservation status. The lollipop catshark was originally described by American ichthyologist Charles Henry Gilbert as "Catulus cephalus", in the 1892 14th volume of "Proceedings of the United States National Museum". His description was based on a long adult male caught from a depth of off Clarion Island

In one case, when a baby had fallen to its death from a tree, the mother came down and stayed by her baby's side for hours waiting vainly for the baby to revive. North American porcupines have a relatively long life expectancy. Some individuals have been found to live up to 30 years of age. Common causes of mortality include predation and starvation.

Nepenthes mikei


undisclosed for conservation purposes, "N. mikei" grows alongside "N. flava". The conservation status of "N. mikei" is listed as Vulnerable on the IUCN Red List, based on an assessment carried out in 2000. This agrees with an informal assessment made by Charles Clarke in 2001, who also classified the species as Vulnerable based on the IUCN criteria. However, Clarke noted that since substantial populations of "N. mikei" lie within protected areas, they "are unlikely to become threatened in the foreseeable future".

Data deficient


A data deficient (DD) species is one which has been categorized by the International Union for Conservation of Nature (IUCN) as offering insufficient information for a proper assessment of conservation status to be made. This does not necessarily indicate that the species has not been extensively studied; but it does indicate that little or no information is available on the abundance and distribution of the species. The IUCN recommends that care be taken to avoid classing species as "data deficient" when the absence of records may indicate dangerously low abundance:

No subpopulations of birds have been evaluated by the IUCN. Additionally 61 avian species (0.59% of those evaluated) are listed as "data deficient", meaning there is insufficient information for a full assessment of conservation status. As these species

Astatotilapia bloyeti


Astatotilapia bloyeti is a species of haplochromine cichlid from the coastal river systems of Tanzania. Reports from other areas of Africa are considered to refer to related species. The IUCN considers it to be endemic to the Pangani River and includes Kenya in its range. This species taxonomic status is uncertain and some authorities place it in the genus "Haplochromis" while others retain it in "Astatotilapia". This taxonomic uncertainty has led the IUCN to classify this species conservation status as Data Deficient. The specific name honours the collector of the type

Phanogomphus diminutus is a species of clubtail dragonfly in the family Gomphidae. It is endemic to the southeastern United States. Its natural habitats are boggy trickles and slow, small streams and lakes, all with part sand, part silt bottoms, and Sphagnum moss margins. The IUCN conservation status of "Phanogomphus diminutus" is "LC", least concern, with no immediate threat to the species' survival. The IUCN status was reviewed in 2018. The species had a Red List assessment of "rare" from 1986 to 1994

The Cape porcupine or South African porcupine, ("Hystrix africaeaustralis"), is a species of Old World porcupine native to central and southern Africa.

Cape porcupines seem to be the world's fourth heaviest living rodents, after the capybara and the Eurasian and North American beavers. They are similar in appearance to, and only slightly larger than, their close relatives, the crested porcupines, and can most easily be distinguished from them by the

Little is known in terms of population numbers elsewhere in Eurasia, with the IUCN estimating between 100 and 10,000 individuals each in China and in Russia, numbers that suggest the species occurs very sparsely in these massive countries. In North Africa, the main occurrence is in Morocco, which is estimated to hold 200 to 500 breeding pairs. There appear to much fewer in other North African

However, the International Union for Conservation of Nature (IUCN) currently lacks enough information to assess its conservation status. In 1906, the Carnegie Museum purchased an extensive collection of fishes assembled from the markets of Takao (Kaohsiung), Taiwan by Hans Sauter.

This species is not dangerous to humans and has no commercial significance; the International Union for Conservation of Nature (IUCN) does not have enough data to assess its conservation status. The blotched catshark was first scientifically described in 1966 by American ichthyologist Stewart Springer, based on a long immature male caught off Cape Canaveral, Florida. He named it after Giles W. Mead, who brought the original specimen to his attention. From 1970 to 1979

The protected area status exists to protect the island as a breeding area for sea birds such as little penguins and silver gulls. The conservation park is classified as an IUCN Category IA protected area. In 1980, it was
