The knobby rocksnail, scientific name Lithasia curta, is a species of medium-sized freshwater snail, an aquatic gilled gastropod mollusk in the family Pleuroceridae. This species is endemic to the United States.
The short-eared dog, also known as the short-eared zorro, small-eared dog, and short-eared jackal, is a unique and elusive canid species endemic to the Amazonian basin. This is the only species assigned to the genus Atelocynus.
The bee genus Anthophora is one of the largest in the family Apidae, with over 450 species worldwide in 14 different subgenera. They are most abundant and diverse in the Holarctic and African biogeographic regions. All species are solitary, though many nest in large aggregations. Nearly all species make nests in the soil, either in banks or in flat ground; the larvae develop in cells with waterproof linings and do not spin cocoons. Males commonly have pale white or yellow facial markings, and/or peculiarly modified leg armature and hairs. Anthophora individuals can be distinguished from the very similar genus Amegilla by the possession of an arolium between the tarsal claws.
A least-concern species is a species that has been categorized by the International Union for Conservation of Nature (IUCN) as evaluated as not being a focus of species conservation because the specific species is still plentiful in the wild. They do not qualify as threatened, near threatened, or conservation dependent.
The Ayumodoki or Kissing Loach is a species of ray-finned fish in the family Botiidae. It is found in lakes and streams on Honshu, the largest island of Japan. Spawning grounds for kissing loach are ditches and small reservoirs for rice cultivation of a river system located in Japan. The kissing loach migrates to flooded areas, including paddy field areas, for spawning in early summer and the spawning of this species is limited after the formation of flooded areas over terrestrial vegetation. In a study conducted by Tsukasa Abe & Tatsuya Sakamoto they test the early development of kissing loach with special reference to the hatching at the early stage as well as the movement of the larvae toward the water surface. The bottoms of these areas, that are reported to be the spawning grounds for these fishes, are covered with vegetation that are submerged by irrigation water for rice cultivation during the spawning period in early summer. It is at this time "(spawning areas submerged for 39 days in 2005), the water depth at the spawning ground was 54.4 ± 0.4 cm [mean ± standard error (SE); 35 days], and the dissolved oxygen at the bottom and near the water surface was measured at 1800 hours for 35 days with a water quality meter. The bottom water temperature was also measured hourly for 35 days using a data logger with a self-contained thermometer" .<ref>Abe, T., Sakamoto, T.

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 (IUCN) Species Survival Commission (SSC) Primate Specialist Group (PSG), the International Primatological Society (IPS), Global Wildlife Conservation (GWC), and Bristol Zoological Society (BZS). The IUCN/SSC PSG worked with Conservation International (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 was a joint project between the three conservation organizations until the 2012–2014 list when BZS was added as a publisher. The 2018–2020 list was the first time Conservation International was not among the publishers, replaced instead by GWC. The list 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,, since then they have been published as independent publications.
