Algae Diverse group of photosynthetic eukaryotic organisms

Algae is an informal term for a large and diverse group of photosynthetic eukaryotic organisms. It is a polyphyletic grouping that includes species from multiple distinct clades. Included organisms range from unicellular microalgae, such as Chlorella, Prototheca and the diatoms, to multicellular forms, such as the giant kelp, a large brown alga which may grow up to 50 metres (160 ft) in length. Most are aquatic and autotrophic and lack many of the distinct cell and tissue types, such as stomata, xylem and phloem, which are found in land plants. The largest and most complex marine algae are called seaweeds, while the most complex freshwater forms are the Charophyta, a division of green algae which includes, for example, Spirogyra and stoneworts.

Brown algae Large group of multicellular algae, comprising the class Phaeophyceae

The brown algae, comprising the class Phaeophyceae, are a large group of multicellular algae, including many seaweeds located in colder waters within the Northern Hemisphere. Most brown algae live in marine environments, where they play an important role both as food and as a potential habitat. For instance, Macrocystis, a kelp of the order Laminariales, may reach 60 m (200 ft) in length and forms prominent underwater kelp forests. Kelp forests like these contain a high level of biodiversity. Another example is Sargassum, which creates unique floating mats of seaweed in the tropical waters of the Sargasso Sea that serve as the habitats for many species. Many brown algae, such as members of the order Fucales, commonly grow along rocky seashores. Some members of the class, such as kelps, are used by humans as food.

Sea lettuce Genus of seaweeds

The sea lettuces comprise the genus Ulva, a group of edible green algae that is widely distributed along the coasts of the world's oceans. The type species within the genus Ulva is Ulva lactuca, lactuca being Latin for "lettuce". The genus also includes the species previously classified under the genus Enteromorpha, the former members of which are known under the common name green nori.

The rusty pipistrelle is a species of vesper bat. It is found in Angola, Botswana, Burkina Faso, Central African Republic, Chad, Ethiopia, Ghana, Kenya, Malawi, Mozambique, Namibia, Nigeria, Senegal, South Africa, Sudan, Tanzania, Uganda, Zambia, and Zimbabwe. Its natural habitats are dry and moist savanna. It is of note as perhaps Africa's smallest bat, at average weight of 3.5 g (0.12 oz).

<i>Herpestes</i> Genus within the mongoose family

Herpestes is a genus within the mongoose family Herpestidae. It is the type genus of the family and comprises ten living species, with several subspecies. Fossil remains of three prehistoric species were excavated in France and described in 1853.

Viverrinae Subfamily of carnivores

The Viverrinae represent the largest subfamily within the Viverridae comprising five genera, which are subdivided into 22 species native to Africa and Southeast Asia. This subfamily was denominated and first described by John Edward Gray in 1864.

<i>Viverra</i> Genus of carnivores

Viverra is a mammalian genus that was first nominated and described by Carl Linnaeus in 1758 as comprising several species including the large Indian civet. The genus was subordinated to the viverrid family by John Edward Gray in 1821.

Plant Kingdom of mainly multicellular, predominantly photosynthetic eukaryotes

Plants are mainly multicellular organisms, predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, plants were treated as one of two kingdoms including all living things that were not animals, and all algae and fungi were treated as plants. However, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes. By one definition, plants form the clade Viridiplantae, a group that includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, mosses, and the green algae, but excludes the red and brown algae.

Red algae Division of archaeplastids

Red algae, or Rhodophyta, are one of the oldest groups of eukaryotic algae. The Rhodophyta also comprises one of the largest phyla of algae, containing over 7,000 currently recognized species with taxonomic revisions ongoing. The majority of species (6,793) are found in the Florideophyceae (class), and mostly consist of multicellular, marine algae, including many notable seaweeds. Red algae are abundant in marine habitats but are relatively rare in freshwaters. Approximately 5% of the red algae occur in freshwater environments with greater concentrations found in warmer areas. Except for two coastal cave dwelling species in the asexual class Cyanidiophyceae, there are no terrestrial species, which may be due to an evolutionary bottleneck where the last common ancestor lost about 25% of its core genes and much of its evolutionary plasticity.

The Worlds 25 Most Endangered Primates Wikipedia list article

The World's 25 Most Endangered Primates is a list of highly endangered primate species selected and published by the International Union for Conservation of Nature Species Survival Commission Primate Specialist Group, the International Primatological Society (IPS), and Conservation International (CI). The 2012–2014 list added the Bristol Conservation and Science Foundation (BCSF) to the list of publishers. The IUCN/SSC PSG worked with CI to start the list in 2000, but in 2002, during the 19th Congress of the International Primatological Society, primatologists reviewed and debated the list, resulting in the 2002–2004 revision and the endorsement of the IPS. The publication has since been a joint project between the three conservation organizations and has been revised every two years following the biannual Congress of the IPS. Starting with the 2004–2006 report, the title changed to "Primates in Peril: The World's 25 Most Endangered Primates". That same year, the list began to provide information about each species, including their conservation status and the threats they face in the wild. The species text is written in collaboration with experts from the field, with 60 people contributing to the 2006–2008 report and 85 people contributing to the 2008–2010 report. The 2004–2006 and 2006–2008 reports were published in the IUCN/SSC PSG journal Primate Conservation, while the 2008–2010 and 2010-2012 report were published as independent publications by all three contributing organizations.

<i>Porolithon</i> Genus of algae

Porolithon is a genus of red algae comprising 24 species. The Porolithon are the primary reef building algae. When coral reefs reach sea level, the corals break under the high energy impact of the waves, while the coralline red algae, primarily Porolithon, continuing building and cementing the reef structure.

Lobophora is a genus of thalloid brown alga comprising approximately ten species. The thalli are flattened against the substrate or erect and grow from a matted, rhizoidal holdfast. The fronds are up to 20 cm (8 in) long and are broadly fan-shaped or have irregularly arranged lateral branches. The sporangial sori are scattered on both surfaces of the thalli or are arranged in concentric bands.

Acrosorium is a genus of marine red algae. The species name origin is Latin, which means finely-veined.

Acrosorium polyneurum is a species of red algae first described by Okamura. It grows in intertidal and shallow subtidal waters in Japan where it is grazed by the sea urchin Hemicentrotus pulcherrimus.
