Agelaia Multipicta
''Agelaia multipicta'' is a swarm-founding, highly eusocial wasp that lives in Mexico, Argentina, Trinidad and southern Brazil. It nests in natural cavities such as hollow trees and aggressively defends the nest from ants, who are brood predators. The workers and queens are morphologically distinguished by ovarian development as well as external features such as a larger petiole and gaster in the queen. Like other carrion-eating ( necrophagous) wasp species, ''A. multipicta'' plays a scavenging role in the ecosystem. ''Agelaia multipicta'' was described by the Irish entomologist Alexander Henry Haliday in 1836. Description James Carpenter's taxonomic key describes characteristic features of this species such as that the "hind-wing with jugal lobe normal, not reduced," and that the head has an occipital carina present. Additionally, in ''A. multipicta'' Carpenter notes the " pronotum without sinuous carina" and the "body without pale maculations, cuticle partly to entirely blu ...

Alexander Henry Haliday
Alexander Henry Haliday (1806–1870, also known as Enrico Alessandro Haliday, Alexis Heinrich Haliday, or simply Haliday) was an Ireland, Irish entomologist. He is primarily known for his work on Hymenoptera, Diptera, and Thysanoptera, but worked on all insect orders and on many aspects of entomology. Haliday was born in Carnmoney, County Antrim later living in Holywood, County Down, Holywood, County Down, Ireland. A boyhood friend of Robert Templeton, he divided his time between Ireland and Lucca, where he co-founded the La Società Entomologica Italiana, Italian Entomological Society with Camillo Rondani and Adolfo Targioni Tozzetti. He was a member of the Royal Irish Academy, the Belfast Natural History Society, the Royal Microscopical Society, Microscopical Society of London, and the Galileiana Academy of Arts and Science, as well as a fellow of the (now Royal) Royal Entomological Society, Entomological Society of London. Alexander Haliday was among the greatest dipterists ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tempera
Tempera (), also known as egg tempera, is a permanent, fast-drying painting medium consisting of pigments mixed with a water-soluble binder medium, usually glutinous material such as egg yolk. ''Tempera'' also refers to the paintings done in this medium. Tempera paintings are very long-lasting, and examples from the first century AD still exist. Egg tempera was a primary method of painting until after 1500 when it was superseded by oil painting. A paint consisting of pigment and binder commonly used in the United States as poster paint is also often referred to as "tempera paint", although the binders in this paint are different from traditional tempera paint. Etymology The term ''tempera'' is derived from the Italian ''dipingere a tempera'' ("paint in distemper"), from the Late Latin ''distemperare'' ("mix thoroughly"). History Tempera painting has been found on early Egyptian sarcophagus decorations. Many of the Fayum mummy portraits use tempera, sometimes in comb ...

Forest Fragmentation
Habitat fragmentation describes the emergence of discontinuities (fragmentation) in an organism's preferred environment (habitat), causing population fragmentation and ecosystem decay. Causes of habitat fragmentation include geological processes that slowly alter the layout of the physical environment (suspected of being one of the major causes of speciation), and human activity such as land conversion, which can alter the environment much faster and causes the extinction of many species. More specifically, habitat fragmentation is a process by which large and contiguous habitats get divided into smaller, isolated patches of habitats. Definition The term habitat fragmentation includes five discrete phenomena: * Reduction in the total area of the habitat * Decrease of the interior: edge ratio * Isolation of one habitat fragment from other areas of habitat * Breaking up of one patch of habitat into several smaller patches * Decrease in the average size of each patch of habit ...

Citrus
''Citrus'' is a genus of flowering trees and shrubs in the family Rutaceae. Plants in the genus produce citrus fruits, including important crops such as oranges, mandarins, lemons, grapefruits, pomelos, and limes. ''Citrus'' is native to South Asia, East Asia, Southeast Asia, Melanesia, and Australia. Indigenous people in these areas have used and domesticated various species since ancient times. Its cultivation first spread into Micronesia and Polynesia through the Austronesian expansion (–1500 BCE). Later, it was spread to the Middle East and the Mediterranean () via the incense trade route, and from Europe to the Americas. Renowned for their highly fragrant aromas and complex flavor, citrus are among the most popular fruits in cultivation. With a propensity to hybridize between species, making their taxonomy complicated, there are numerous varieties encompassing a wide range of appearance and fruit flavors.

Matão
Matão is a municipality in the state of São Paulo in Brazil. As of 2020, the town had an estimated population of 83,626 and a population density of 146.3 persons per km2. The total area the city is . Matão sits at an elevation of . The municipality consists of two districts: Matão and São Lourenço do Turvo. History Matão was first populated by coffee growers at the beginning of the 1890s. The settlers constructed a small chapel in 1894, and in 1895 called their settlement Senhor do Bom Jesus das Palmeiras. The settlement was renamed Matão in 1897 and became a district of Araraquara. It became an independent municipality on August 27, 1898. The region attracted more small-scale farmers in the 1890s, and development was furthered by the construction of a railroad line, the Estrada de Ferro Araraquara, which was built to connect Rio Claro, in São Paulo State, to Cuiabá, the capital city of Mato Grosso. The rail line reached Matão by 1899. The municipality comprised thr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rural
In general, a rural area or a countryside is a geographic area that is located outside towns and cities. Typical rural areas have a low population density and small settlements. Agricultural areas and areas with forestry are typically described as rural, as well as other areas lacking substantial development. Different countries have varying definitions of ''rural'' for statistical and administrative purposes. Rural areas have unique economic and social dynamics due to their relationship with land-based industry such as agriculture, forestry, and resource extraction. Rural economics can be subject to boom and bust cycles and vulnerable to extreme weather or natural disasters, such as droughts. These dynamics alongside larger economic forces encouraging urbanization have led to significant demographic declines, called rural flight, where economic incentives encourage younger populations to go to cities for education and access to jobs, leaving older, less educated and ...

Forest
A forest is an ecosystem characterized by a dense ecological community, community of trees. Hundreds of definitions of forest are used throughout the world, incorporating factors such as tree density, tree height, land use, legal standing, and ecological function. The United Nations' Food and Agriculture Organization (FAO) defines a forest as, "Land spanning more than 0.5 hectares with trees higher than 5 meters and a Canopy (biology), canopy cover of more than 10 percent, or trees able to reach these thresholds ''in situ''. It does not include land that is predominantly under agricultural or urban use." Using this definition, ''Global Forest Resources Assessment (FRA), Global Forest Resources Assessment 2020'' found that forests covered , or approximately 31 percent of the world's land area in 2020. Forests are the largest Terrestrial ecosystem, terrestrial ecosystems of Earth by area, and are found around the globe. 45 percent of forest land is in the Tropical forest, trop ...

Gaster (insect Anatomy)
The gaster () is the bulbous posterior portion of the metasoma found in hymenopterans of the suborder Apocrita (bees, wasps and ants). This begins with abdomen, abdominal segment III on most ants, but some make a constricted Petiole (insect anatomy) , postpetiole out of segment III, in which case the gaster begins with abdominal segment IV. The gaster in ants contains what is sometimes called the "social stomach," which is named for the fact that food can be carried within it and then shared with other members of the colony. It also contains the ant's heart as well as the rest of their digestive system. In the ant subfamily Formicinae, the gaster houses an acidiphore which they can use to spray formic acid. Certain ants in the genus ''Cataglyphis'', including ''Cataglyphis bicolor'' and ''Cataglyphis fortis'', have a cubiform petiole that allows them to decrease their inertia (and therefore increase their speed) by raising their gaster into an upright position. The ant speci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Petiole (insect Anatomy)
In entomology, petiole is the technical term for the narrow waist of some hymenopteran insects, especially ants, bees, and wasps in the suborder Apocrita. The petiole can consist of either one or two segments, a characteristic that separates major subfamilies of ants. Structure The term 'petiole' is most commonly used to refer to the constricted first (and sometimes second) metasomal (posterior) segment of members of the hymenopteran suborder Apocrita (ants, bees, and wasps). It is sometimes also used to refer to other insects with similar body shapes, where the metasomal base is constricted. The petiole is occasionally called a pedicel, but in entomology, that term is more correctly reserved for the second segment of the antenna; while in arachnology, ' pedicel' is the accepted term to define the constriction between the cephalothorax and abdomen of spiders. The plump portion of the abdomen posterior to the petiole (and postpetiole in the Myrmicinae Myrmicinae is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
