Carl Peter Holbøll
Carl Peter Holbøll (1795–1856) was an officer in the Danish Royal Navy, Greenland colonial officer and explorer of the Greenlandic fauna. Holbøll served as Royal Inspector of Colonies and Whaling in North Greenland (1825–1828), then Inspector of South Greenland (1828–1856). While in this post he became interested in natural history. His main contribution was to send large amounts of faunistic collections to the zoologists in Copenhagen. For example, professor Johannes Theodor Reinhardt described the North American form of the red-necked grebe and named it ''Podiceps holboellii'' (now ''Podiceps grisegena holboellii''). Holbøll himself also wrote a treatise on Greenlandic birds.Ornithologischer Beitrag zur Fauna Grönlands' von Carl Holböll, übersetzt und mit einem Anhang versehen von J.H. Paulsen. Leipzig, Ernst Fleischer. 1846. In the paper, he described the hoary redpoll (''Linota hornemanni'', now known as ''Carduelis hornemanni''), which he named for the botan ...

South Greenland
The Southern Inspectorate of Greenland also known as South Greenland was a Danish inspectorate on Greenland consisting of the trading centers and missionary stations along the southwest coast of the island. Its capital was at Godthaab (modern Nuuk). The northernmost town of South Greenland was Holsteinborg, which bordered Egedesminde, which was the southernmost town of North Greenland. This boundary between South and North Greenland ran at around 68°N degree of latitude, and in the South, South Greenland stretched to 59°30'N, p. 281 ''CHAP.

Red-necked Grebe
The red-necked grebe (''Podiceps grisegena'') is a migratory aquatic bird found in the temperate regions of the northern hemisphere. Its wintering habitat is largely restricted to calm waters just beyond the waves around ocean coasts, although some birds may winter on large lakes. Grebes prefer shallow bodies of fresh water such as lakes, marshes or fish-ponds as breeding sites. The red-necked grebe is a nondescript dusky-grey bird in winter. During the breeding season, it acquires the distinctive red neck plumage, black cap and contrasting pale grey face from which its name was derived. It also has an elaborate courtship display and a variety of loud mating calls. Once paired, it builds a nest from water plants on top of floating vegetation in a shallow lake or bog. Like all grebes, the Red-necked is a good swimmer, a particularly swift diver, and responds to danger by diving rather than flying. The feet are positioned far back on the body, near the tail, which makes the bird ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gastropoda
The gastropods (), commonly known as snails and slugs, belong to a large taxonomic class of invertebrates within the phylum Mollusca called Gastropoda (). This class comprises snails and slugs from saltwater, from freshwater, and from land. There are many thousands of species of sea snails and slugs, as well as freshwater snails, freshwater limpets, and land snails and slugs. The class Gastropoda contains a vast total of named species, second only to the insects in overall number. The fossil history of this class goes back to the Late Cambrian. , 721 families of gastropods are known, of which 245 are extinct and appear only in the fossil record, while 476 are currently extant with or without a fossil record. Gastropoda (previously known as univalves and sometimes spelled "Gasteropoda") are a major part of the phylum Mollusca, and are the most highly diversified class in the phylum, with 65,000 to 80,000 living snail and slug species.

Amphipoda
Amphipoda is an order of malacostracan crustaceans with no carapace and generally with laterally compressed bodies. Amphipods range in size from and are mostly detritivores or scavengers. There are more than 9,900 amphipod species so far described. They are mostly marine animals, but are found in almost all aquatic environments. Some 1,900 species live in fresh water, and the order also includes the terrestrial sandhoppers such as ''Talitrus saltator''. Etymology and names The name ''Amphipoda'' comes, via New Latin ', from the Greek roots 'on both/all sides' and 'foot'. This contrasts with the related Isopoda, which have a single kind of thoracic leg. Particularly among anglers, amphipods are known as ''freshwater shrimp'', ''scuds'', or ''sideswimmers''. Description Anatomy The body of an amphipod is divided into 13 segments, which can be grouped into a head, a thorax and an abdomen. The head is fused to the thorax, and bears two pairs of antennae and one pair of s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ceratiidae
Sea devils are the family of deep-sea anglerfish known as the Ceratiidae, from the Greek ''keras'', "horn", referring to the bioluminescent lure that projects from the fishes' forehead. They are among the most widespread of the anglerfishes, found in all oceans from the tropics to the Antarctic. They are large and elongated: females of the largest species, Krøyer's deep sea angler fish, ''Ceratias holboelli'', reach in length. Males, by contrast, are much smaller, reaching , and, like other anglerfishes, spend much of their lives attached to a female after a free-living adolescent stage in which they are very small – at most – and have sharp, beak-like, toothless jaws. One or more males attach themselves permanently to a female, eventually merging circulatory systems. As this genetic chimera matures, the male grows large testicles, while the rest of its body atrophies. Ceratiidae are the only creatures known to become chimeras as a normal part of their lifecycle Life ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henrik Nikolai Krøyer
Henrik Nikolai Krøyer (22 March 1799 – 14 November 1870) was a Denmark, Danish zoologist. Born in Copenhagen, he was a brother of the composer Hans Ernst Krøyer. He started studying medicine at the University of Copenhagen in 1817, which he later changed to history and philology. While a student, he was a supporter of the Philhellenism, Philhellenic movement, and he participated as a volunteer in the Greek War of Independence along with several fellow students. Upon his return to Denmark, Krøyer gained an interest in zoology. In 1827, he took the position as assistant teacher in Stavanger, where he met, and later married, Bertha Cecilie Gjesdal. Bertha's sister, Ellen Cecilie Gjesdal, was deemed unfit to bring up her child, so Henrik and Bertha adopted the boy, who took on the name Peder Severin Krøyer, and later became a well-known painter. Krøyer returned to Copenhagen in 1830 where he was employed as a teacher in natural history at the Military Academy. As the course l ...

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 intera ...

Botanist
Botany, also called , plant biology or phytology, is the science of plant life and a branch of biology. A botanist, plant scientist or phytologist is a scientist who specialises in this field. The term "botany" comes from the Ancient Greek word (''botanē'') meaning "pasture", " herbs" "grass", or " fodder"; is in turn derived from (), "to feed" or "to graze". Traditionally, botany has also included the study of fungi and algae by mycologists and phycologists respectively, with the study of these three groups of organisms remaining within the sphere of interest of the International Botanical Congress. Nowadays, botanists (in the strict sense) study approximately 410,000 species of land plants of which some 391,000 species are vascular plants (including approximately 369,000 species of flowering plants), and approximately 20,000 are bryophytes. Botany originated in prehistory as herbalism with the efforts of early humans to identify – and later cultivate – edible, med ...

Boechera Holboellii
''Boechera holboellii'', or Holbøll's rockcress, is a species of plant in the family Brassicaceae. Its cytology has been much studied by the Danish botanist Tyge W. Böcher. Circumscription of this species has varied, with earlier works treating it as a widespread, polymorphic species with several varieties, while more recently it has been treated as a much more narrowly defined species from Greenland. The rust fungus '' Puccinia monoica'' infects the plant leading to pseudoflowers, which mimic those of yellow, early spring wildflowers (e.g. buttercups), not only in visible light but also in ultraviolet.Roy BA: Floral mimicry by a plant pathogen.
