Centris Xochipillii
The genus ''Centris'' contains circa 250 species of large apid bees occurring in the Neotropical and Nearctic realms, from Kansas to Argentina. Most females of these bees possess adaptations for carrying floral oils rather than (or in addition to) pollen or nectar. They mainly visit plants of the family Malpighiaceae to collect oil, but also visit others such as Plantaginaceae, Calceolariaceae, and Krameriaceae. Recent studies have shown they are sister to the corbiculate bees, the most well-known and economically important group of bees They are large (up to 3 cm), fast-flying bees, distinguished from the closely related genus '' Epicharis'' by the absence of long, whip-like setae that project backwards from just behind the eyes. They are commonly encountered bees in American deserts, and are active at very high ambient temperatures when many other species are in hiding. They can often be seen in large numbers on desert-willow (''Chilopsis'') and palo verde (''Parki ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Seta
In biology, setae (singular seta ; from the Latin word for " bristle") are any of a number of different bristle- or hair-like structures on living organisms. Animal setae Protostomes Annelid setae are stiff bristles present on the body. They help, for example, earthworms to attach to the surface and prevent backsliding during peristaltic motion. These hairs make it difficult to pull a worm straight from the ground. Setae in oligochaetes (a group including earthworms) are largely composed of chitin. They are classified according to the limb to which they are attached; for instance, notosetae are attached to notopodia; neurosetae to neuropodia. Crustaceans have mechano- and chemosensory setae. Setae are especially present on the mouthparts of crustaceans and can also be found on grooming limbs. In some cases, setae are modified into scale like structures. Setae on the legs of krill and other small crustaceans help them to gather phytoplankton. It captures them and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Adolpho Ducke
Adolpho Ducke (October 19, 1876 – January 5, 1959), (also referred to as Adolfo Ducke and occasionally misspelled "Duque"), was a notable entomologist, botanist and ethnographer specializing in Amazonia. According to family records, he was an ethnic German with roots in Trieste Austro-Hungary (now in Italy). German was his first language; that is, the German commonly spoken in Trieste in the 19th century. Most of his books were written in German. Recruited by Emílio Goeldi, Ducke began his work in Amazônia as an entomologist for the Museu Paraense Emílio Goeldi, but due to the influence of botanists Jacques Hüber and Paul Le Cointe, he switched to botany. He traveled throughout Amazônia to study the complicated tree system of the rainforest. He published 180 articles and monographs, primarily on the Leguminosae, and he described 900 species and 50 new genera. In 1918, while continuing his work for the Paraense Museum, he collaborated with the Rio de Janeiro Botanic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Entomologist
Entomology () is the scientific study of insects, a branch of zoology. In the past the term "insect" was less specific, and historically the definition of entomology would also include the study of animals in other arthropod groups, such as arachnids, myriapods, and crustaceans. This wider meaning may still be encountered in informal use. Like several of the other fields that are categorized within zoology, entomology is a taxon-based category; any form of scientific study in which there is a focus on insect-related inquiries is, by definition, entomology. Entomology therefore overlaps with a cross-section of topics as diverse as molecular genetics, behavior, neuroscience, biomechanics, biochemistry, systematics, physiology, developmental biology, ecology, morphology, and paleontology. Over 1.3 million insect species have been described, more than two-thirds of all known species. Some insect species date back to around 400 million years ago. They have many kinds of ...

Behavioral Ecology
Behavioral ecology, also spelled behavioural ecology, is the study of the evolutionary basis for ethology, animal behavior due to ecology, ecological pressures. Behavioral ecology emerged from ethology after Niko Tinbergen outlined Tinbergen's four questions, four questions to address when studying animal behaviors: What are the proximate causes, ontogeny, Adaption, survival value, and phylogeny of a behavior? If an organism has a trait that provides a selective advantage (i.e., has adaptive significance) in its environment, then natural selection favors it. Adaptive significance refers to the expression of a trait that affects fitness, measured by an individual's reproductive success. Adaptive traits are those that produce more copies of the individual's genes in future generations. Maladaptive traits are those that leave fewer. For example, if a bird that can call more loudly attracts more mates, then a loud call is an adaptive trait for that species because a louder bird mates ...

Centris Pallida
''Centris pallida'' is a species of solitary bee native to North America. It lacks an accepted common name; however, it has been called the digger bee, the desert bee, and the pallid bee due to its actions, habitat, and color respectively. The solitary nature of this bee allows for a dual-strategy mating system which produces an evolutionarily stable state resistant to invading strategies. These bees have also evolved to withstand the high temperatures of their native habitat. ''C. pallida'' routinely has internal temperatures within 3 degrees Celsius of death. Taxonomy and phylogenetics ''Centris pallida'' was officially discovered and catalogued by William J. Fox in 1899 near Phoenix, Arizona. Fox also discovered '' Centris cockerelli'', '' Centris errans'', and ''Sphex subhyalinus''. This species is closely related to ''Centris cockerelli'' in terms of habitat and genus, but is different in terms of mating, color, and subgenus. This bee also belongs to the superfamily Apoidea ...

Mating System
A mating system is a way in which a group is structured in relation to sexual behaviour. The precise meaning depends upon the context. With respect to animals, the term describes which males and females mate under which circumstances. Recognised systems include monogamy, polygamy (which includes polygyny, polyandry, and polygynandry), and promiscuity, all of which lead to different mate choice outcomes and thus these systems affect how sexual selection works in the species which practice them. In plants, the term refers to the degree and circumstances of outcrossing. In human sociobiology, the terms have been extended to encompass the formation of relationships such as marriage. In plants The primary mating systems in plants are outcrossing (cross-fertilisation), autogamy (self-fertilisation) and apomixis (asexual reproduction without fertilization, but only when arising by modification of sexual function). Mixed mating systems, in which plants use two or even all three mating ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cashew
The cashew tree (''Anacardium occidentale'') is a tropical evergreen tree native to South America in the genus ''Anacardium'' that produces the cashew seed and the cashew apple accessory fruit. The tree can grow as tall as , but the dwarf cultivars, growing up to , prove more profitable, with earlier maturity and greater yields. The cashew seed is commonly considered a snack nut (cashew nut) eaten on its own, used in recipes, or processed into cashew cheese or cashew butter. Like the tree, the nut is often simply called a cashew. Cashew allergies are triggered by the proteins found in tree nuts, and cooking often does not remove or change these proteins. In 2019, four million tonnes of cashew nuts were produced globally, with Ivory Coast and India as the leading producers. As well as the nut and fruit, the plant has several other uses. The shell of the cashew seed yields derivatives that can be used in many applications including lubricants, waterproofing, paints, and, s ...
