Acromyrmex Pubescens
''Acromyrmex pubescens'' is a species of New World ants of the subfamily Myrmicinae of the genus ''Acromyrmex''. They are native to Paraguay. Description Like other members of the genus ''Acromyrmex'' and the closely related genus ''Atta (genus), Atta'', ''Acromyrmex pubescens'' are commonly known as "leafcutter ants". ''Acromyrmex pubescens'' has four pairs of spines and a rough exoskeleton, features which distinguish it and other members of the genus ''Acromyrmex'' from the genus ''Atta''. The pair of front spines are longer than the pair of middle spines, similar to ''Acromyrmex lundii'', but unlike ''A. lundii'', ''A. pubescens'' is covered with dense sometimes overlapping fuzz on their bodies. Taxonomy ''Acromyrmex pubescens'' were first described by the Italian entomologist Carlo Emery in 1905. They were originally classified as a subspecies of ''Acromyrmex lundii'' because of their structural similarity. They were named 'pubescens' (Latin for "wikt:downy, downy") because ...

Carlo Emery
Carlo Emery (25 October 1848, Naples – 11 May 1925) was an Italian entomologist. He is remembered for Emery's rule, which states that insect social parasites are often closely related to their hosts. Early in his career Carlo Emery pursued a course in general medicine, and in 1872 narrowed his interests to ophthalmology. In 1878 he was appointed Professor of Zoology at the University of Cagliari, remaining there for several years until 1881 when he took up an appointment at the University of Bologna as Professor of Zoology, remaining there for thirty-five years until his death. Emery specialised in Hymenoptera, but his early work was on Coleoptera. Prior to 1869, his earliest works were a textbook of general zoology and papers on fishes and molluscs. From 1869 to 1925 he devoted himself almost entirely to the study of ants. Emery published extensively between 1869 and 1926 describing 130 genera and 1057 species mainly in Wytsman's ''Genera Insectorum'' series. Emery†...

Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics ( morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides whe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gran Chaco
The Gran Chaco or Dry Chaco is a sparsely populated, hot and semiarid lowland natural region of the RĂo de la Plata basin, divided among eastern Bolivia, western Paraguay, northern Argentina, and a portion of the Brazilian states of Mato Grosso and Mato Grosso do Sul, where it is connected with the Pantanal region. This land is sometimes called the Chaco Plain. Toponymy The name Chaco comes from a word in Quechua, an indigenous language from the Andes and highlands of South America. The Quechua word ''chaqu'' meaning "hunting land" comes probably from the rich variety of animal life present throughout the entire region. Geography The Gran Chaco is about 647,500 km² (250,000 sq mi) in size, though estimates differ. It is located west of the Paraguay River and east of the Andes, and is mostly an alluvial sedimentary plain shared among Paraguay, Bolivia, and Argentina. It stretches from about 17 to 33°S latitude and between 65 and 60°W longitude, though es ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leucocoprinus
''Leucocoprinus'' is a genus of fungi in the family Agaricaceae. Its best-known member is the distinctive yellow mushroom '' Leucocoprinus birnbaumii'', which is found in plant pots and greenhouses worldwide. The type species is '' Leucocoprinus cepistipes''. The genus has a widespread distribution and contains over 80 recognised species, however many of these species are very scarcely recorded and little known with only a small number of ''Leucocoprinus'' species which are commonly observed. The majority of the species in this genus are exclusive to tropical environments however numerous species have become a common sight in plant pots and greenhouses resulting in them becoming well known worldwide. It is likely that some of the observations for these common species are misidentified with observations for ''L. birnbaumii'' in particular often being conflated with other species simply because it is better known or more frequently suggested by image recognition algorithms.

Fungi
A fungus ( : fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, Protozoa, and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related organisms, named the ''Eumycota'' (''t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mutualism (biology)
Mutualism describes the ecological interaction between two or more species where each species has a net benefit. Mutualism is a common type of ecological interaction. Prominent examples include most vascular plants engaged in mutualistic interactions with mycorrhizae, flowering plants being pollinated by animals, vascular plants being dispersed by animals, and corals with zooxanthellae, among many others. Mutualism can be contrasted with interspecific competition, in which each species experiences ''reduced'' fitness, and exploitation, or parasitism, in which one species benefits at the expense of the other. The term ''mutualism'' was introduced by Pierre-Joseph van Beneden in his 1876 book ''Animal Parasites and Messmates'' to mean "mutual aid among species". Mutualism is often conflated with two other types of ecological phenomena: cooperation and symbiosis. Cooperation most commonly refers to increases in fitness through within-species (intraspecific) interactions, alth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Downy
Downy, also known as Lenor in Europe, Russia and Japan, is a brand of fabric softener produced by Procter & Gamble that was introduced in 1960. Lenor is a brand name of fabric softener and dryer sheets, also produced by P&G, sold in Europe, Russia and Japan. Lenor fabric softener had entered China in 2007 but was subsequently discontinued. Scent beads under the brand Downy have been sold in China since December 2017. Plans to rebrand Lenor as Downy in the UK were dropped in 2002. For the company's national and international experience in sustainable development, and eco-friendly products, the Environment Possibility Award conferred the "Environmental Heroes of the Year" to Downy in 2012. Amy Sedaris and Tituss Burgess are the talents hired to promote the Downy/Lenor ''Unstopables'' In-Wash Scent Boosters range in both the US and the UK. The commercials were filmed by Grey Advertising.

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leafcutter Ants
Leafcutter ants, a non-generic name, are any of 47 species of leaf-chewing ants belonging to the two genera '' Atta'' and ''Acromyrmex''. These species of tropical, fungus-growing ants are all endemic to South and Central America, Mexico, and parts of the southern United States.. Leafcutter ants can carry twenty times their body weight and cut and process fresh vegetation (leaves, flowers, and grasses) to serve as the nutritional substrate for their fungal cultivates. ''Acromyrmex'' and ''Atta'' ants have much in common anatomically; however, the two can be identified by their external differences. ''Atta'' ants have three pairs of spines and a smooth exoskeleton on the upper surface of the thorax, while ''Acromyrmex'' ants have four pairs and a rough exoskeleton. The exoskeleton itself is covered in a thin layer of mineral coating, composed of rhombohedral crystals that are generated by the ants. Next to humans, leafcutter ants form some of the largest and most complex animal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atta (genus)
''Atta'' is a genus of New World ants of the subfamily Myrmicinae. It contains at least 17 known species. ''Atta'' leaf-cutter ants are relatively large, rusty red or brown in colour, and have a spiny body and long legs. The three main castes within a nest are the queen, worker, and soldier. Only the queens and males have wings (alate), and these ants are also known as reproductives or swarmers. Although most of the ants in the nest are female, only the queens produce eggs. Queens are usually over long. Overview Ants of the genus ''Atta'' are leafcutter ants that comprise one of the two genera of leafcutting ants within the tribe Attini, along with ''Acromyrmex''. They have no sting, thus inject no venom, although they are known as strong biters. ''Atta'' spp. exhibit a high degree of polymorphism, with four castes being present in established colonies: minims (or garden ants), minors, mediae, and majors (also called soldiers or dinergates).
