Nils Samuel Swederus
Nils Samuel Swederus also Svederus (24 August 1751 – 1833) was a Swedish naturalist. His parents were Sigtuna Magnus Svederus and Anna Maria Christiernin. Nils Samuel Swederus studied theology and other disciplines at the University of Uppsala. He was ordained in 1780 and became a ''hofpredikanten'' or Royal Court chaplain in 1782. From 1784 to 1786 he made scientific trips to several European countries—to England, France, Belgium and the Netherlands. In 1789 he became Vicar of Nasby and Ervalla parishes and dean of Fellingsbro Fellingsbro (, locally ) is a locality and a parish situated in Lindesberg Municipality, Örebro County, Sweden with 1,384 inhabitants in 2010. It is home to the Fellingsbro folk high school. History The parish of Fellingsbro is mentioned already ....

Blister Beetle
Blister beetles are beetles of the family Meloidae, so called for their defensive secretion of a blistering agent, cantharidin. About 7,500 species are known worldwide. Many are conspicuous and some are aposematically colored, announcing their toxicity to would-be predators. Description Blister beetles are hypermetamorphic, going through several larval stages, the first of which is typically a mobile triungulin. The larvae are insectivorous, mainly attacking bees, though a few feed on grasshopper eggs. While sometimes considered parasitoids, in general, the meloid larva apparently consumes the immature host along with its provisions, and can often survive on the provisions alone; thus it is not an obligatory parasitoid, but rather a facultative parasitoid, or simply a kleptoparasite. The adults sometimes feed on flowers and leaves of plants of such diverse families as the Amaranthaceae, Asteraceae, Fabaceae, and Solanaceae. Cantharidin, a poisonous chemical that causes bl ...

Galápagos Islands
The Galápagos Islands (Spanish: , , ) are an archipelago of volcanic islands. They are distributed on each side of the equator in the Pacific Ocean, surrounding the centre of the Western Hemisphere, and are part of the Republic of Ecuador. Located west of continental Ecuador, the islands are known for their large number of endemic species that were studied by Charles Darwin during the second voyage of HMS ''Beagle''. His observations and collections contributed to the inception of Darwin's theory of evolution by means of natural selection. The Galápagos Islands and their surrounding waters form the Galápagos Province of Ecuador, the Galápagos National Park, and the Galápagos Marine Reserve. The principal language on the islands is Spanish. The islands have a population of slightly over 25,000. The first recorded visit to the islands happened by chance in 1535, when Fray Tomás de Berlanga, the Bishop of Panamá, was surprised to find this undiscovered land on a vo ...

Brood Parasite
Brood parasites are animals that rely on others to raise their young. The strategy appears among birds, insects and fish. The brood parasite manipulates a host, either of the same or of another species, to raise its young as if it were its own, usually using egg mimicry, with eggs that resemble the host's. The evolutionary strategy relieves the parasitic parents from the investment of rearing young. This benefit comes at the cost of provoking an evolutionary arms race between parasite and host as they coevolve: many hosts have developed strong defenses against brood parasitism, such as recognizing and ejecting parasitic eggs, or abandoning parasitized nests and starting over. It is less obvious why most hosts do care for parasite nestlings, given that for example cuckoo chicks differ markedly from host chicks in size and appearance. One explanation, the mafia hypothesis, proposes that parasitic adults retaliate by destroying host nests where rejection has occurred; there is ...

Xylocopa Darwini
''Xylocopa darwini'', the Galápagos carpenter bee, is the only native species of bee in the Galápagos Islands, to which it is endemic. Altogether, only three species of bee are found in the islands. This species found on 75% of the largest islands. It is sexually dimorphic and is known for its complex behavior. As the only native bee, ''Xylocopa darwini'' serves as an important primary pollinator within the plant-pollinator network of the archipelago. Description The leaf-cutter bee and the wool carder bee are introduced, making the Galápagos carpenter bee the only native species. As a sexually dimorphic species, the male and female bees look different. The female bee is dark and shiny with black setae, and is commonly found throughout the year. The male is rarer, with a black abdomen and yellow-brown setae. A rare specimen in the Smithsonian collection exhibits gynandromorphism, with a visually female left side and a visually male right side. Distribution Galapagos c ...

Beetles Described In 1787
Beetles are insects that form the order Coleoptera (), in the superorder Endopterygota. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 described species, is the largest of all orders, constituting almost 40% of described insects and 25% of all known animal life-forms; new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species. Found in almost every habitat except the sea and the polar regions, they interact with their ecosystems in several ways: beetles often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates. Some species are serious agricultural pests, such as the Colorado potato beetle, while others such as Coccinellidae (ladybirds or ladybugs) eat aphids, scale insects, thrips, and other plant-sucking insects that damage crops. Beetles typically have a particularly hard exoske ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
