Neolanidae
Desidae is a family of spiders, some of which are known as intertidal spiders. The family is named for the genus '' Desis'', members of which live in a very unusual location — between the tides. The family has been reevaluated in recent years and now includes inland genera and species as well, such as ''Badumna'' and ''Phryganoporus''. In 2017, the family Amphinectidae was merged into Desidae. The family Toxopidae has been separated off. Those intertidal spiders that are truly marine commonly live in barnacle shells, which they seal up with silk; this allows them to maintain an air bubble during high tide. They emerge at night to feed on various small arthropods that live in the intertidal zone. Distribution As now circumscribed, the family Desidae is mainly found in South America and Australasia, with some species reaching north to Malaysia. ''Metaltella simoni'' has been introduced in a large part of the Southern United States (records exist from California, Louisiana, Mississ ...

Badumna Insignis
The black house spider or common black spider (''Badumna insignis'') is a common species of cribellate Australian spider, introduced to New Zealand and Japan. A closely related species, ''Badumna longinqua'', the grey house spider, has a similar distribution, but has also been introduced to the Americas. Ludwig Carl Christian Koch described ''Badumna insignis'' in 1872. Description ''B. insignis'' is a dark, robust spider. The female grows up to 18 mm, with a 30 mm leg span. As with most spiders, the males are smaller (10 mm) and have longer legs in relation to their body size. In both sexes, the carapace and legs are dark brown to black, and the abdomen is charcoal grey with a dorsal pattern of light markings (sometimes indistinct) and a dense covering of fine, velvety hair. ''B. longinqua'' is slightly bigger (14 mm) with a greyish carapace and black-brown legs. Habits, mating, and reproduction The web of ''B. insignis'' is a messy-looking construct of i ...

World Spider Catalog
The World Spider Catalog (WSC) is an online searchable database concerned with spider taxonomy. It aims to list all accepted families, genera and species, as well as provide access to the related taxonomic literature. The WSC began as a series of individual web pages in 2000, created by Norman I. Platnick of the American Museum of Natural History. After Platnick's retirement in 2014, the Natural History Museum of Bern (Switzerland) took over the catalog, converting it to a relational database. , 50,151 accepted species were listed. The order Araneae Spiders (order Araneae) are air-breathing arthropods that have eight legs, chelicerae with fangs generally able to inject venom, and spinnerets that extrude silk. They are the largest order of arachnids and rank seventh in total species dive ... (spiders) has the seventh-most species of all orders. The existence of the World Spider Catalog makes spiders the largest taxon with an online listing that is updated regularly. It ha ...

Titanoecidae
Titanoecidae is a family of araneomorph spiders first described by Pekka T. Lehtinen in 1967. It is fairly widespread in the New World and Eurasia with five genera and more than 50 species worldwide. These are mostly dark-colored builders of "woolly" (cribellate) silk webs. Several species are found at relatively high altitudes in mountain ranges and may be very common in such habitats. Genera , the World Spider Catalog accepts the following genera: *''Anuvinda'' Lehtinen, 1967 – Asia *''Goeldia'' Keyserling, 1891 – South America, Mexico *''Nurscia'' Simon, 1874 – Asia, Europe *''Pandava'' Lehtinen, 1967 – Asia, Africa, Papua New Guinea *''Titanoeca'' Thorell, 1870 – Asia, North America, Europe, Ecuador, Algeria See also * List of Titanoecidae species * Titanoecoidea The Titanoecoidea or titanoecoids are a proposed taxon of araneomorph spiders at the superfamily rank.

Local Extinction
Local extinction, also known as extirpation, refers to a species (or other taxon) of plant or animal that ceases to exist in a chosen geographic area of study, though it still exists elsewhere. Local extinctions are contrasted with global extinctions. Local extinctions mark a change in the ecology of an area. In recent times, local extinction has sometimes been followed by a replacement of the species taken from other locations; wolf reintroduction is an example of this. The term "local extinction" is highly vernacular. The more proper biological term is ''extirpation''. Discussion Glaciation can lead to local extinction. This was the case during the Pleistocene glaciation event in North America. During this period, most of the native North American species of earthworm were killed in places covered by glaciation. This left them open for colonization by European earthworms brought over in soil from Europe. Species naturally become extirpated from islands over time. The number ...

Invasive Species
An invasive species otherwise known as an alien is an introduced organism that becomes overpopulated and harms its new environment. Although most introduced species are neutral or beneficial with respect to other species, invasive species adversely affect habitats and bioregions, causing ecological, environmental, and/or economic damage. The term can also be used for native species that become harmful to their native environment after human alterations to its food webfor example the purple sea urchin (''Strongylocentrotus purpuratus'') which has decimated kelp forests along the northern California coast due to overharvesting of its natural predator, the California sea otter (''Enhydra lutris''). Since the 20th century, invasive species have become a serious economic, social, and environmental threat. Invasion of long-established ecosystems by organisms is a natural phenomenon, but human-facilitated introductions have greatly increased the rate, scale, and geographic range of ...
