Riparian Myotis
The riparian myotis (''Myotis riparius''), is a vespertilionid bat species from South and Central America. It is a medium-sized bat compared to other South American myotis. Taxonomy The riparian myotis was originally described as a subspecies of velvety myotis in 1960. In 1973, it was raised to the species level. Description The riparian myotis has long, woolly fur. The dorsal fur can vary geographically from a reddish to a blackish tinge. Individuals in the south tend to have a darker dorsal region, and individuals in the north tend to have a reddish dorsal region. The dorsal hairs are unicolor and the plagiopatagium is broadly attached to the foot at the base of the toes. The ears are short compared to the eyes and nostrils. The tragus is pointed and curves slightly outward. The ventral hairs are bicolored, with a dark-brown base and yellowish tips. Range and habitat ''M. riparius'' is distributed widely throughout the neotropical region, and occurs from Honduras southward ...

Charles Overton Handley
Charles Overton Handley, Jr. (July 14, 1924 - June 9, 2000) was a zoologist and explorer who conducted various expeditions for the United States government. Born in Longview, Texas, Handley's father was a professor of wildlife management and an avid bird-watcher. In the summer after his high school graduation, Handley participated in an expedition to collect mammals in the Southern Appalachian mountains, with the Museum of Zoology of the University of Michigan. He thereafter resolved to study mammals. Handley received a B.A. from Virginia Tech in 1944, and served in World War II as a rifleman in the 120th Infantry, seeing action in Europe. After the war, the secretary of the Smithsonian Institution, Alexander Wetmore, hired Handley to collect birds and mammals on a naval icebreaker expedition to the Arctic. Handley received an M.A. from the University of Michigan in 1947, and a Ph.D. in mammalogy from that institution in 1955, in the interim participating in expeditions to the High ...

Mammals Described In 1960
Mammals () are a group of vertebrate animals constituting the class Mammalia (), characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles (including birds) from which they diverged in the Carboniferous, over 300 million years ago. Around 6,400 extant species of mammals have been described divided into 29 orders. The largest orders, in terms of number of species, are the rodents, bats, and Eulipotyphla (hedgehogs, moles, shrews, and others). The next three are the Primates (including humans, apes, monkeys, and others), the Artiodactyla (cetaceans and even-toed ungulates), and the Carnivora (cats, dogs, seals, and others). In terms of cladistics, which reflects evolutionary history, mammals are the only living members of the Synapsida (synapsids); this clade, together with Sauropsida ...

Mouse-eared Bats
The mouse-eared bats or myotises are a diverse and widespread genus (''Myotis'') of bats within the family Vespertilionidae. The noun "''myotis''" itself is a New Latin construction, from the Greek language, Greek "''muós'' (meaning "mouse") and "''oûs''" (meaning ear), literally translating to "mouse-eared". Relationships ''Myotis'' has historically been included in the subfamily Vespertilioninae, but was classified in its own subfamily, Myotinae, by Nancy Simmons in 1998. In her 2005 classification in ''Mammal Species of the World'', Simmons listed the genera ''Cistugo'' and ''Lasionycteris'' in the Myotinae in addition to ''Myotis'' itself.Simmons, 2005, p. 499 However, molecular data indicate that ''Cistugo'' is distantly related to all other Vespertilionidae, so it was reclassified into its own family, the Cistugidae, and that ''Lasionycteris'' belongs in the Vespertilioninae.Roehrs et al., 2010 The genus ''Submyotodon'' has since been added to the subfamily, making it and ...

Velvety Free-tailed Bat
The velvety free-tailed bat or Pallas's mastiff bat (''Molossus molossus''), is a bat species in the family Molossidae. Description ''M. molossus'' is a medium-sized bat, with a length of and with a wingspan of . This species is brown in color; however, when seen flying around at dusk, it will appear to be black. The tail of ''M. molossus'' is long and extends beyond the tail membrane. Its ears are large and round. Feeding ''M. molossus'' forages in open areas, above tree canopies, around forest edges, and around streams and ponds. Its diet includes moths, beetles, and flying ants. It is commonly seen at dusk, where it will fly solo, catching insects in the air. Distribution and habitat It occurs in the Americas from Argentina north to Cuba and Mexico and also the Florida Keys in the United States. It is very common in the Caribbean. A ''M. molossus'' has been observed being killed by a giant centipede (''Scolopendra viridicornis'') in the Amazon. The lone bat had been roost ...

Silver-tipped Myotis
The silver-tipped myotis (''Myotis albescens'') is a species of mouse-eared bat found in a range of lowland habitats in the Americas. It is part of the vesper bat genus ''Myotis'', which includes many common species across the world. Genetic analysis suggests that it is probably most closely related to a group of Neotropical ''Myotis'' species that includes '' Myotis nigricans'', '' Myotis levis'', and '' Myotis oxyotus'', or alternatively to '' Myotis dominicensis'' alone. Description The silver-tipped myotis is a small bat, with a total length of , and a tail long. The fur is long and silky, with individual hairs being black or dark brown for most of their length, but white at the tips. This silver ticking gives the bat its common name and "frosted" appearance. Although fur with a similar pattern is found on the undersides of some related species, only in the silver-tipped myotis does it extend across the entire body, thus enabling it to be distinguished from some otherwise ve ...

Savanna
A savanna or savannah is a mixed woodland-grassland (i.e. grassy woodland) ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach the ground to support an unbroken herbaceous layer consisting primarily of grasses. According to '' Britannica'', there exists four savanna forms; ''savanna woodland'' where trees and shrubs form a light canopy, ''tree savanna'' with scattered trees and shrubs, ''shrub savanna'' with distributed shrubs, and ''grass savanna'' where trees and shrubs are mostly nonexistent.Smith, Jeremy M.B.. "savanna". Encyclopedia Britannica, 5 Sep. 2016, https://www.britannica.com/science/savanna/Environment. Accessed 17 September 2022. Savannas maintain an open canopy despite a high tree density. It is often believed that savannas feature widely spaced, scattered trees. However, in many savannas, tree densities are higher and trees are more regularly spaced than in for ...

Rainforests
Rainforests are characterized by a closed and continuous tree canopy, moisture-dependent vegetation, the presence of epiphytes and lianas and the absence of wildfire. Rainforest can be classified as tropical rainforest or temperate rainforest, but other types have been described. Estimates vary from 40% to 75% of all biotic species being indigenous to the rainforests. There may be many millions of species of plants, insects and microorganisms still undiscovered in tropical rainforests. Tropical rainforests have been called the "jewels of the Earth" and the " world's largest pharmacy", because over one quarter of natural medicines have been discovered there. Rainforests as well as endemic rainforest species are rapidly disappearing due to deforestation, the resulting habitat loss and pollution of the atmosphere. Definition Rainforest are characterized by a closed and continuous tree canopy, high humidity, the presence of moisture-dependent vegetation, a moist layer of leaf ...

Uruguay
Uruguay (; ), officially the Oriental Republic of Uruguay ( es, República Oriental del Uruguay), is a country in South America. It shares borders with Argentina to its west and southwest and Brazil to its north and northeast; while bordering the Río de la Plata to the south and the Atlantic Ocean to the southeast. It is part of the Southern Cone region of South America. Uruguay covers an area of approximately and has a population of an estimated 3.4 million, of whom around 2 million live in the metropolitan area of its capital and largest city, Montevideo. The area that became Uruguay was first inhabited by groups of hunter–gatherers 13,000 years ago. The predominant tribe at the moment of the arrival of Europeans was the Charrúa people, when the Portuguese first established Colónia do Sacramento in 1680; Uruguay was colonized by Europeans late relative to neighboring countries. The Spanish founded Montevideo as a military stronghold in the early 18th century bec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paraguay
Paraguay (; ), officially the Republic of Paraguay ( es, República del Paraguay, links=no; gn, Tavakuairetã Paraguái, links=si), is a landlocked country in South America. It is bordered by Argentina to the south and southwest, Brazil to the east and northeast, and Bolivia to the northwest. It has a population of seven million, nearly three million of whom live in the capital and largest city of Asunción, and its surrounding metro. Although one of only two landlocked countries in South America (Bolivia is the other), Paraguay has ports on the Paraguay and Paraná rivers that give exit to the Atlantic Ocean, through the Paraná-Paraguay Waterway. Spanish conquistadores arrived in 1524, and in 1537, they established the city of Asunción, the first capital of the Governorate of the Río de la Plata. During the 17th century, Paraguay was the center of Jesuit missions, where the native Guaraní people were converted to Christianity and introduced to European culture. ...
