Yellow-crested Helmetshrike
The yellow-crested helmetshrike (''Prionops alberti'') or King Albert's helmetshrike is a species of bird in the Vanga family Vangidae. This large, striking helmetshrike is unique in its black plumage and bright yellow crest. Though this species has been encountered broadly across the mountains of the eastern Democratic Republic of the Congo, there is still much to learn about this species. It is rarely reported due to the majority of its distribution occurring in relatively remote regions within the Albertine Rift, an area with ongoing armed conflict. Description Appearance Adults are generally all black with a bright yellow or gold crest (sometimes described as a "helmet"), with the yellow extending across the entire top half of the head above the eyeline and extending backwards behind the eye. The greenish-yellow irides are surrounded by an orange eye-wattle; the bill, like the plumage, is black, though the legs and feet are reported to be light red. Individuals can be quit ...

Arthropod
Arthropods ( ) are invertebrates in the phylum Arthropoda. They possess an arthropod exoskeleton, exoskeleton with a cuticle made of chitin, often Mineralization (biology), mineralised with calcium carbonate, a body with differentiated (Metamerism (biology), metameric) Segmentation (biology), segments, and paired jointed appendages. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one. They form an extremely diverse group of up to ten million species. Haemolymph is the analogue of blood for most arthropods. An arthropod has an open circulatory system, with a body cavity called a haemocoel through which haemolymph circulates to the interior Organ (anatomy), organs. Like their exteriors, the internal organs of arthropods are generally built of repeated segments. They have ladder-like nervous systems, with paired Anatomical terms of location#Dorsal and ventral, ventral Ventral nerve cord, nerve cord ...

Insectivore
file:Common brown robberfly with prey.jpg, A Asilidae, robber fly eating a hoverfly An insectivore is a carnivore, carnivorous animal or plant which eats insects. An alternative term is entomophage, which can also refer to the Entomophagy in humans, human practice of eating insects. The first vertebrate insectivores were amphibians. When they evolved 400 million years ago, the first amphibians were piscivores, with numerous sharp conical teeth, much like a modern crocodile. The same tooth arrangement is however also suited for eating animals with exoskeletons, thus the ability to eat insects can stem from piscivory. At one time, insectivorous mammals were scientific classification, scientifically classified in an order (biology), order called Insectivora. This order is now abandoned, as not all insectivorous mammals are closely related. Most of the Insectivora taxa have been reclassified; those that have not yet been reclassified and found to be truly related to each ...

Altitudinal Migration
Altitudinal migration is a short-distance animal migration from lower altitudes to higher altitudes and back. Altitudinal migrants change their elevation with the seasons making this form of animal migration seasonal. Altitudinal migration can be most commonly observed in species inhabiting temperate or tropical ecosystems. This behavior is commonly seen among avian species but can also be observed within other vertebrates and some invertebrates. It is commonly thought to happen in response to climate and food availability changes as well as increasingly due to anthropogenic influence. These migrations can occur both during reproductive and non-reproductive seasons. The patterns of altitudinal migration may be affected by climate change resulting in potentially life-threatening situations for some species. Deforestation can affect the migration corridors of altitudinal migrant and could lead to smaller areas for these species to migrate. Changes in the environment of altitudinally ...

Mummy
A mummy is a dead human or an animal whose soft tissues and Organ (biology), organs have been preserved by either intentional or accidental exposure to Chemical substance, chemicals, extreme cold, very low humidity, or lack of air, so that the recovered body does not Corpse decomposition, decay further if kept in cool and dry conditions. Some authorities restrict the use of the term to bodies deliberately embalming, embalmed with chemicals, but the use of the word to cover accidentally desiccation, desiccated bodies goes back to at least the early 17th century. Mummies of humans and animals have been found on every continent, both as a result of natural preservation through unusual conditions, and as cultural artifacts. Over one million Animal mummy, animal mummies have been found in Egypt, many of which are cats. Many of the Egyptian animal mummies are African sacred ibis, sacred ibis, and radiocarbon dating suggests the Egyptian ibis mummies that have been analyzed were from ...

Albertine Rift Montane Forests
The Albertine Rift montane forests ( French: ''Forêts montagnardes du Rift Albertin'') is a tropical moist broadleaf forest ecoregion in east-central Africa. The ecoregion covers the mountains of the northern Albertine Rift, and is home to distinct Afromontane forests with high biodiversity. Geography The high montane forests cover the western portions of Rwanda and Burundi, the eastern edge of the Democratic Republic of the Congo, and portions of western Uganda and Tanzania. This area occupies the parallel Albertine Rift Mountains that enclose the western branch of the East African Rift. The mountain ranges include the Lendu Plateau of Uganda (the forest is almost completely cleared from here), and the Virunga Mountains and Rwenzori Mountains of Rwanda, Uganda, and the Democratic Republic of the Congo. At the highest elevations of the Rwenzori and Virunga ranges (above 3000 meters), the forests transition to the Afroalpine Rwenzori–Virunga montane moorlands ecoregion ...

Montane Forest
Montane ecosystems are found on the slopes of mountains. The alpine climate in these regions strongly affects the ecosystem because temperatures lapse rate, fall as elevation increases, causing the ecosystem to stratify. This stratification is a crucial factor in shaping plant community, biodiversity, metabolic processes and ecosystem dynamics for montane ecosystems. Dense montane forests are common at moderate elevations, due to moderate temperatures and high rainfall. At higher elevations, the climate is harsher, with lower temperatures and higher winds, preventing the growth of trees and causing the plant community to transition to montane grasslands and shrublands or alpine tundra. Due to the unique climate conditions of montane ecosystems, they contain increased numbers of endemic species. Montane ecosystems also exhibit variation in ecosystem services, which include carbon storage and water supply. Life zones As elevation increases, the alpine climate, climate becomes co ...

Habitat
In ecology, habitat refers to the array of resources, biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species' habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as Biophysical environment, environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and Luminous intensity, light intensity. Biotic index, Biotic factors include the availability of food and the presence or absence of Predation, predators. Every species has particular habitat requirements, habitat generalist species are able to thrive in a wide array of environmental conditions while habitat specialist species require a very limited set of factors to survive. The habitat of a species is not necessarily found in a ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
