Hymenophyllum refrondescens is a species of fern in the family Hymenophyllaceae. It is endemic to Ecuador. Its natural habitat is subtropical or tropical moist lowland forests. It is threatened by habitat loss.
The conservation status of a group of organisms indicates whether the group still exists and how likely the group is to become extinct in the near future. Many factors are taken into account when assessing conservation status: not simply the number of individuals remaining, but the overall increase or decrease in the population over time, breeding success rates, and known threats. Various systems of conservation status exist and are in use at international, multi-country, national and local levels as well as for consumer use.
Notiosorex cockrumi, also called Cockrum's gray shrew or Cockrum's desert shrew, is a tiny species of shrews named in 2003. This red-toothed shrew, which is as light as a penny, is the first new mammal species from Arizona since 1977. Its range extends from Arizona to central Sonora, Mexico.
A species that is extinct in the wild (EW) is one that has been categorized by the International Union for Conservation of Nature as known only by living members kept in captivity or as a naturalized population outside its historic range due to massive habitat loss.
Bannerman's weaver is a species of bird in the weaver family, Ploceidae. It is found in Cameroon and Nigeria. Its natural habitat is subtropical or tropical moist montane forests. It is threatened by habitat loss.
The Somali hedgehog is a species of mammal in the family Erinaceidae. It is endemic to Somalia and Somaliland. The Somali hedgehog is nocturnal.
Bulimulus sp. nov. 'josevillani' is an undescribed species of tropical air-breathing land snail, a pulmonate gastropod mollusk in the subfamily Bulimulinae.
Hymenophyllum alveolatum is a species of fern in the family Hymenophyllaceae. It is endemic to Ecuador. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist montane forests. It is threatened by habitat loss.
Hymenophyllum is a genus of ferns in the family Hymenophyllaceae. Its name means "membranous leaf", referring to the very thin translucent tissue of the fronds, which gives rise to the common name filmy fern for this and other thin-leaved ferns. The leaves are generally only one cell thick and lack stomata, making them vulnerable to desiccation. Consequently, they are found only in very humid areas, such as in moist forests and among sheltered rocks. They are small and easy to overlook.
Hymenophyllum brachypus is a species of fern in the family Hymenophyllaceae. It is endemic to Ecuador. Its natural habitat is subtropical or tropical moist lowland forests. It is threatened by habitat loss.
Hymenophyllum contractile is a species of fern in the family Hymenophyllaceae. It is endemic to Ecuador. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist montane forests. It is threatened by habitat loss.
Hymenophyllum cristatum is a species of fern in the family Hymenophyllaceae. It is endemic to Ecuador. Its natural habitats are subtropical or tropical moist montane forests and subtropical or tropical high-altitude grassland. It is threatened by habitat loss.
Hymenophyllum helicoideum is a species of fern in the family Hymenophyllaceae. It is endemic to Ecuador. Its natural habitat is subtropical or tropical moist lowland forests. It is threatened by habitat loss.
Hymenophyllum megistocarpum is a species of fern in the family Hymenophyllaceae. It is endemic to Ecuador, where it has not been seen since the original collection in 1935. It was found in wet forest habitat at an elevation of 3200 meters in the Andes. The area is undergoing habitat degradation.
Hymenophyllum nanum is a species of fern in the family Hymenophyllaceae. It is endemic to Ecuador, where it is known from two old collections in Pichincha Province. Its natural habitat is the forest of the lower Andes. It is threatened by habitat loss.
Hymenophyllum sodiroi is a species of fern in the family Hymenophyllaceae. It is endemic to Ecuador. Its natural habitat is subtropical or tropical moist montane forests. It is threatened by habitat loss.
Hymenophyllum tenerum is a species of fern in the family Hymenophyllaceae. It is endemic to Ecuador. Its natural habitat is subtropical or tropical moist montane forests. It is threatened by habitat loss.
Hymenophyllum trifidum is a species of fern in the family Hymenophyllaceae. It is endemic to Ecuador. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist montane forests. It is threatened by habitat loss.
Hymenophyllum tunbrigense, the Tunbridge filmy fern or Tunbridge filmy-fern, is a small, fragile perennial leptosporangiate fern which forms large dense colonies of overlapping leaves from creeping rhizomes. The common name derives from the leaves which are very thin, only a single cell thick, and translucent, giving the appearance of a wet film. The evergreen fronds are bipinnatifid, deeply and irregularly dissected, about 3 to 6 cm long, 2 cm across with dark winged stipes. In contrast to the similar H. wilsonii the fronds are more divided, flattened, appressed to the substrate and tend to have a bluish tint.
