The division name was derived from the genus name Marchantia, named by French botanist Jean Marchant after his father. It is estimated that there are about 9000 species of liverworts. [ 4 ] Some of the more familiar species grow as a flattened leafless thallus , but most species are leafy with a form very much like a flattened moss .
The name comes from the Ancient Greek word ἀνωφελής anōphelḗs 'useless', derived from ἀν-an-, 'not', 'un-' and ὄφελος óphelos 'profit'. [8] The taxonomy of the genus was greatly advanced in 1901 when the English entomologist Frederick Vincent Theobald described 39 Anopheles species in his 5-volume monograph on the ...
The resulting thinning of the forest canopy leads to the drying of the moss mats that are essential for the spider's survival, as it requires climates of high and constant humidity. [3] These spiders have survived in temperatures that range between -17.8 °C or 0 °F and 19.8 °C or 67.6 °F within mountainous regions of the Southern Appalachians.
Ctenizidae (/ ˈ t ə n ɪ z ə d iː / tə-NIZZ-ə-dee) [2] is a small family of mygalomorph spiders that construct burrows with a cork-like trapdoor made of soil, vegetation, and silk. . They may be called trapdoor spiders, as are other, similar species, such as those of the families Liphistiidae, Barychelidae, and Cyrtaucheniidae, and some species in the Idiopidae and Nemesiid
The moss life-cycle starts with a haploid spore that germinates to produce a protonema (pl. protonemata), which is either a mass of thread-like filaments or thalloid (flat and thallus-like). Massed moss protonemata typically look like a thin green felt, and may grow on damp soil, tree bark, rocks, concrete, or almost any other reasonably stable ...
Latrodectus is a broadly distributed genus of spiders with several species that are commonly known as the true widows.This group is composed of those often loosely called black widow spiders, brown widow spiders, and similar spiders.
The name mantodea is formed from the Ancient Greek words μάντις (mantis) meaning "prophet", and εἶδος (eidos) meaning "form" or "type". It was coined in 1838 by the German entomologist Hermann Burmeister. [2] [3] The name "mantid" properly refers only to members of the family Mantidae, which was, historically, the only family in the ...
