SOS Report 1 State of Observed Species 2010 FAQs Why are 2008 numbers reported? Species are described in thousands of journals, books, and other publications around the globe. We report numbers for the most recent calendar year for which reasonably complete compilations exist. Thus, SOS 2010 summarizes those species officially described and named in 2008.

What is a “new species”? New species didn’t just appear. We estimate that Earth is home to more than 10,000,000 plants and animals and perhaps tens of millions of microbes. Scientists add an average of two species per hour or about 18,000 species each year to our inventory of life. Thousands of scientists are searching for new species at field study sites in every ecosystem on our planet and are steadily improving our knowledge of them. Most species remain unknown to science, inaccessible to those who seek to study, conserve, or use them.

The most difficult part of recognizing a species as new to science is learning every species already known in a group. Taxonomists master a body of knowledge that dates from 1753 (for plants) or 1758 (for most animals) in order to know a new species when they encounter one. Many new species are discovered in the course of compre- hensive comparative studies of all species of a group. Such studies are known as taxonomic revisions or mono- graphs. Between revisions, hundreds or thousands of specimens may have accumulated in natural history muse- ums or herbaria around the world. Among them will be specimens that refine and improve our understanding of already known species and others representing species new to science. These, combined with specimens newly collected in the field, are the raw material for new species.

Who are the species explorers? Taxonomy is the science of species exploration. Taxonomists are responsible for discovering, describing, naming, and classifying species. There are so many species on Earth that no one is capable of learning them all. Taxono- mists thus specialize, focusing on the study of particular groups such as plants (botany), insects (entomology), or fishes (ichthyology).

What are type specimens? Types are designated from among the original specimens from which new species are named and described. Types are not necessarily typical in any particular anatomical or genetic sense, but rather add stability to the use of scien- tific names. As new evidence is collected and our knowledge of species improves, a previously described species might be divided into more than one species or combined with some other species. Wherever the type specimen falls in regard to the latest theory of species, the name follows.

Natural history collections (and type culture collections in the case of many microbes) are the necessary physical evidence of species diversity and the material basis for taxonomy. It is estimated that there are about 3 billion specimens in the world’s natural history collections. These make theories about species testable and verifiable.

What is “cybertaxonomy”? Taxonomists are currently modernizing their science, adapting information science infrastructure and tools to accel- erate the process of species exploration. Such cyber-enabled taxonomy is called “cybertaxonomy”. This includes both the specialized tools that allow taxonomists to do taxonomy better and faster (such as accessing museum specimens, historical literature, and digital instruments), as well as a new generation of Web accessible resources for users of taxonomic information. Examples of the latter include the Encyclopedia of Life which is creating a Web page for every species ( www.eol.org ); ZooBank that is striving to register new species of animals to make them immediately accessible ( www.zoobank.org ); the Global Biodiversity Information Facility (GBIF) which is mobilizing data records for billions of specimens in natural history collections around the world ( www.gbif.org ); and the Biodi- versity Heritage Library project which has already scanned more than 29,000,000 pages of historical natural history publications ( www.biodiversitylibrary.org ).

data summaries

Mammalia: Of the 213 mammals discovered in 2008, only 41 new species (19.25%) were extant – i.e., currently living. Almost 32% of these new living mammals were rodents and almost all of these were Muridae , the largest Family of living mammals which includes rats, mice and gerbils.

Fishes: Across all living Chordata, the 505 new fishes comprised the largest group of species described in 2008 (58.8%). Almost 84% (n = 423) of these new fish species were in the Class Actinopterygii and over half of the new Actinopterygii were in the Order Perciformes (n = 138) or the Order Siluriformes (n = 108).

Aves (Birds): Only 32 species of birds were described as new in 2008 and of those, just seven (21.9%) are currently living. These extant species represented the Order Passeriformes (n=6) and Order Procel- lariiformes (n=1) and spanned six Families: Hydrobatidae (Storm-petrels, the smallest seabirds), Sylvii- dae (the Old World or “True” Warblers), Timaliidae (Old World Babblers), Turdidae (Thrushes), Tyranni- dae (Tyrant Flycatchers) and the Zosteropidae (the White-eyes).

Amphibia & Reptilia: The newly described amphibians and reptiles in 2008 were tied for extant species at 129 each. This represented 15% of the new Chordata but less than 1% of the total new extant species reported across the Kingdoms and Phyla. Almost 90% of the extant amphibians were frogs — the Order Anura (n=116) — and over 37% of the total newly described reptiles (n=206) were fossil species (n = 77 fossils). These reptile fossils included the dinosaur Orders Saurischia (n=15) and Ptero- sauria (n = 7).

Dinosaurs: Offering evidence of migration from Asia to the Western Hemisphere, one of the newly described reptiles in 2008 was Albertonykus borealis — a type of tyrannosaur about the size of a chicken and believed to be the smallest North American dinosaur yet discovered ( Longrich et al, 2008 ). Also newly described in 2008 was the Nemicolopterus crypticus, a “winged lizard” or flying dinosaur from the Pterodactyloidea suborder — more commonly known as the pterodactyls.

Insecta: Insects represent the greatest number of animal species on the planet and almost half (48.25%) of all living new species described in 2008 were Insecta. Over 36% of the newly described insects in 2008 were in the Order Coleoptera (beetles) followed by moths & butterflies (Order Lepidop- tera) at 15.7% and the “true flies” (Order Diptera) at 15.2%.

Mollusca: Newly described fossil Mollusca species easily surpassed the newly described fossil Insecta (n=327) in 2008. Over one-fifth of the new fossil animalia species in 2008 were mollusks (n = 448) and was by far, the greatest number of new fossils across all animal Phyla and Classes.

Gastropoda: The gastropod Class— terrestrial, marine and freshwater slugs and snails — comprised the vast majority of the 880 new living species of mollusks described in 2008 (83.0%). Almost 60% of the new gastropods described in 2008 were the marine Hypsogastropoda (or seasnails).

& facts

Crustacea: 1,014 extant Crustacea were newly described in 2008 and of these, over 46% were in the Class Ostracoda, or seed shrimp. Reports of known or described living Crustracean are estimated at 50,000 species. Within Crustracea, the Ostracoda class has 65,000 total species with approximately 20% of those species living (Brusca, R.C. and G.J. Brusca. Invertebrates. 2nd edition . Sinauer Associ- ates, Sunderland, MA. 936 pp). In 2008, 594 new ostracods were described and of those, 21.2% were fossils.

Arachnida: Over 90% of the 1,320 extant Arachnida species newly described in 2008 were in two Or- ders: Araneae (n = 612) — the spiders — and the Acari (n = 578) e.g., ticks and mites. Two of the new Araneae species were Amazon tarantulas in the Genus Pamphobeteus which includes some of the largest spiders in the world ( Bertani et al, 2008 ). Seven new Arachnida fossils were described in 2008 which was less than 1% of the total new Arachnids reported (n = 1,327).

Plantae: Of the 2,080 vascular plants that were described in 2008, over 31% belonged to just two groups: Order Asparagales (n = 510) and Order Lamiales (n = 136). Over 26% belonged to just two families: Orchidaceae (n = 428) and Asteraceae (n = 131).

Orchids: The Bulbophyllum genus in the Orchidaceae family is considered to be the largest genus in the Plantae kingdom with over 1900 species including several species that have been recognized by the IUCN has having threatened status. In 2008, 94 new species were discovered in this very diverse genus — the most of any plant genus.

Mints: Over one-third of the new Lamiales species described in 2008 belonged to the mint Family La- miaceae (n = 48) and 13 of those new Lamiaceae were in the genus Hemigenia. Another 11 newly described species were in the genus Salvia which is much commonly known as sage but also contains ornamental flowers simply called Salvia.

Algae: Nearly species of algae have been described since 1753 — or, about 112 new algae species per year (Michael Guiry, 2010). 2008 represents the lowest number of newly described algae species in the past 10 years (n = 61) while the most new algae descriptions in the same time period occurred in year 2000 with 232 new species. The rate of algae exploration in 2008 is surprising given the increased interest in algae in alternative fuel research.

Fungi: In 2008, 1,344 new extant species were described and over 48% of those were in the Division Ascomycota. Sometimes called sac fungi, a few of the better known Ascomycota (or ascomycetes) are truffles, brewer’s/baker’s yeast (for beer and bread), and as pathogens for plants (e.g., Dutch Elm’s Dis- ease) and humans (yeast infections). Probably the best known Ascomycota is the mold, Penicillium chrysogenum, the source of penicillum.

Prokaryotes: In addition to the 573 new Prokaryote species described in 2008, there were 116 new Genera; 11 new Families; five new Orders; and one new Class placed in the Bacteria and Archaea kingdoms. Over 38% of all newly described Prokaryote species were in the Phylum Proteobacteria that includes the salmonella pathogen.
