Centris Labrosa
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 (''Parkinso ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Seta
In biology, setae (; seta ; ) are any of a number of different bristle- or hair-like structures on living organisms. Animal setae Protostomes Depending partly on their form and function, protostome setae may be called macrotrichia, chaetae, Scale (insect anatomy), scales, or Common name, informally, hairs. The setal membrane is not Cuticle, cuticularized, so movement is possible. Annelid setae are stiff bristles present on the body. They allow earthworms and their relatives 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 (the 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. The setae on polychaete worms are referred to as chaeta due to their differing morphology. Crustaceans have mechano- and chemos ...

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 Bot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Entomologist
Entomology (from Ancient Greek ἔντομον (''éntomon''), meaning "insect", and -logy from λόγος (''lógos''), meaning "study") is the branch of zoology that focuses on insects. Those who study entomology are known as entomologists. 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. The field is also referred to as insectology in American English, while in British English insectology implies the study of the relationships between insects and humans. Over 1.3million insect species have been described by entomology. History Entomology is rooted in nearly all human cultures from prehistoric times, primarily in the context of agriculture (especially biological control and beekeeping). The natural Roman philosopher Pliny the Elder (23–79 CE) wrote a book on the kinds of insects, while the scientist of Kufa, ...

John Alcock (behavioral Ecologist)
John Alcock (; November 13, 1942 – January 15, 2023) was an American behavioral ecologist and author. He was the Emeritus' Professor in the School of Life Sciences at Arizona State University. His research interests include the evolution of diversity in insect populations, studying the adaptive value of different ways in which males find mating partners. He authored several books, including ''The Kookaburras' Song: Exploring Animal Behavior in Australia'' (1988), ''Sonoran Desert Summer'' (1990), ''The Triumph of Sociobiology'' (2003), and ''Animal Behavior: An Evolutionary Approach'' (tenth edition, 2013). He authored ''Sonoran Desert Spring'' (1994) which was illustrated by Marilyn Hoff Stewart, and also authored ''In a Desert Garden: Love and Death Among the Insects'' (1999) illustrated by Turid Forsyth. Alcock was one of the original scientists to participate in the Ask A Biologist program. Alcock performed extensive research and was the leading authority on the bee ' ...

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 strategy, 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 belo ...

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 mating, mate under which circumstances. Recognised systems include Monogamy in animals, monogamy, Animal sexual behaviour#Polygamy, polygamy (which includes Polygyny in animals, polygyny, Polyandry in animals, polyandry, and polygynandry), and Promiscuity#Other animals, 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, ...

Cashew
Cashew is the common name of a tropical evergreen tree ''Anacardium occidentale'', in the family Anacardiaceae. It is native to South America and is the source of the cashew nut and the cashew apple, an 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 nut is edible and is eaten on its own as a snack, used in recipes, or processed into cashew cheese or cashew butter. The nut is often simply called a 'cashew'. The cashew apple is a light reddish to yellow fruit, whose pulp and juice can be processed into a sweet, astringent fruit drink or fermented and distilled into liquor. In 2023, 3.9 million tons of cashew nuts were harvested globally, led by the Ivory Coast and India. In addition to the nut and fruit, the shell yields derivatives used in lubricants, waterproofing, and paints. Description The cashew tree is large and evergreen, growing to tall, with a s ...
