Sarkidiornis is a genus within the family Anatidae. Sarkidiornis is sometimes considered a monotypic genus with its sole member the knob-billed duck, a cosmopolitan species. Most taxonomic authorities, however, split the species into two:
The Sand Mountain blue is a lycaenid butterfly of the "blue" subfamily that is only found around the Sand Mountain Recreation Area near Fallon, Nevada. It is a subspecies of the pallid blue.
Lake Stymphalia is located in the north-eastern part of the Peloponnese, in Corinthia, southern Greece. It is a closed karst basin with a wetland area and an agrarian area. The lake is an important stopover for migratory birds. The size of the lake varies, depending on the season.
The yellow-striped pygmy eleuth, also known as the yellow-striped dwarf frog, is a species of frog in the family Eleutherodactylidae from closed mesic and xeric forests in Cuba.
Metzgeriaceae is a family of thallose liverworts in the order Metzgeriales. Species may be either monoicous or dioicous.
The Hemiphractidae are a family of frogs from South and Central America. Previously, this group had been classified as a subfamily (Hemiphractinae) under family Hylidae. More recent research classifies these genera into their own family, or sometimes into three separate families: Amphignathodontidae, Cryptobatrachidae, and Hemiphractidae. An active question still exists as to which of these groupings is more accurate.
Cercyonis sthenele, the Great Basin wood-nymph, is a North American butterfly in the family Nymphalidae.
The elegant madtom is a fish native to Tennessee, Alabama, and Kentucky, and is one of twenty-nine species of madtom. It prefers to live in small rivers and gravel-bottomed creeks. The average lifespan of the elegant madtom is two years.
Reticulariaceae is a family of slime molds recognized by the Integrated Taxonomic Information System and is composed of the genera Dictydiaethalium, Enteridium, Lycogala, Reticularia, and Tubifera.
Nabalus barbatus, the barbed rattlesnakeroot, is a plant in the family Asteraceae. It is native to the Southeastern United States where it is found in small numbers in a few disjunct areas of remaining natural grassland. Because of this, it is considered a globally rare species, with only 35-70 remaining populations. Much of its natural habitat of prairie and savanna has been destroyed. In 2010 it was reclassified from the genus Prenanthes to Nabalus.
Usnea strigosa, commonly known as bushy beard lichen, is a fruticose lichen in the family Parmeliaceae.
Hylaeus krombeini is a bee species endemic to Asia.
Hylaeus sedens is a bee species endemic to Asia.
Lasioglossum vagans, also known as the Lasioglossum (Ctenomia) vagans, is a species of bee in the family Halictidae.
Anthidiellum krombeini is a species of leaf-cutting bee in the genus Anthidiellum, of the family Megachilidae.
The Oil Palm Aphid, also known as Schizaphis (Schizaphis) rotundiventris, is an aphid in the superfamily Aphidoidea in the order Hemiptera. It is a true bug and sucks sap from plants.
Ephemera simulans is a species of mayfly. It is commonly found throughout the United States. The species is used for fly fishing.
Culex territans is a species of mosquito in the family Culicidae.
Notiosoricini, whose members are known as the North American gray shrews, is a tribe of shrews in the family Soricidae, including the genera Megasorex and Notiosorex. They are found across the southwestern United States and most of Mexico.
Siphlonisca aerodromia, commonly known as the Tomah mayfly, is an extremely rare species and has only been documented less than 100 times. It was once thought to only known to occur in New York and Northern Maine, but has been since found more recently in eastern Canada as well. The Tomah mayfly is an endangered species and is listed as threatened in both New York and Maine. Its abundance is unknown. The Tomah mayfly is the only species within the monotypic genus Siphlonisca. The Tomah mayfly is a habitat specialist and an indicator species. Adults only live for a few days as they deposit eggs into rivers and streams. Nymphs hatch from eggs and migrate to the floodplains during springtime and following snow melt. They spend most of their lives in the floodplains, feeding on other aquatic invertebrates in order to grow rapidly. The Tomah mayfly was considered as a flagship species and led to the decision not to dam a stream and flood a sedge meadow and therefore conserve the ecosystem.
