Darwin's Frog
Darwin's frog (''Rhinoderma darwinii''), also called the Southern Darwin's frog, is a species of frog of the family Rhinodermatidae. It was discovered by Charles Darwin during his voyage on HMS ''Beagle''. on a trip to Chile. In 1841, French zoologist André Marie Constant Duméril and his assistant Gabriel Bibron described and named Darwin's frog. The diet of ''R. darwinii'' consists mostly of herbivore invertebrates. ''R. darwinii'' is currently classified as an endangered species by the International Union for Conservation of Nature. Darwin's frog has an unusual method of brooding, in which the male will facilitate development of its tadpoles inside its vocal sac. This male brooding may make Darwin's frog unique among extant frog species, as the only other frog that has this behavior is the ''R. rufum'' (northern Darwin's frog), which has been presumed extinct since 1981. Characteristics Size Darwin's frog is a small species with a snout–to–vent length of . The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
André Marie Constant Duméril
André Marie Constant Duméril (1 January 1774 – 14 August 1860) was a French zoologist. He was professor of anatomy at the National Museum of Natural History (France), Muséum national d'histoire naturelle from 1801 to 1812, when he became professor of herpetology and ichthyology. His son Auguste Duméril was also a zoologist, and the author citation (zoology), author citation Duméril is used for both André and his son. Life André Marie Constant Duméril was born on 1 January 1774 in Amiens and died on 14 August 1860 in Paris. He became a doctor at a young age, obtaining, at 19 years, the ''prévot'' of anatomy at the medical school of Rouen. In 1800, he left for Paris and collaborated in the drafting of the comparative anatomy lessons of Georges Cuvier. He replaced Cuvier at the Central School of the Panthéon, Paris, Panthéon and had, as his colleague, Alexandre Brongniart. In 1801, he gave courses to the medical school of Paris.

Lanín National Park
Lanín National Park () is a national park of Argentina, located in the Neuquén Province, with forests of diverse tree varieties, mainly Fagaceae and conifers such as the lenga and the ''Araucaria'', many species of which are not found elsewhere in Argentina. The park contains the Lanín volcano, and the Huechulafquen, Aluminé, and Lácar lakes among other attractions. Sport fishing of salmon and trout is practiced in the lakes and the numerous rivers and streams. The animal life of the park is similar to the southern Nahuel Huapi National Park. The city of San Martín de los Andes on the shore of Lake Lácar serves as hub for tourists visiting the park, as well as to skiers visiting the nearby Chapelco ski centre. Climate The park mostly has a moist temperate In geography, the temperate climates of Earth occur in the middle latitudes (approximately 23.5° to 66.5° N/S of the Equator), which span between the tropics and the polar regions of Earth.

Embryo
An embryo ( ) is the initial stage of development for a multicellular organism. In organisms that reproduce sexually, embryonic development is the part of the life cycle that begins just after fertilization of the female egg cell by the male sperm cell. The resulting fusion of these two cells produces a single-celled zygote that undergoes many cell divisions that produce cells known as blastomeres. The blastomeres (4-cell stage) are arranged as a solid ball that when reaching a certain size, called a morula, (16-cell stage) takes in fluid to create a cavity called a blastocoel. The structure is then termed a blastula, or a blastocyst in mammals. The mammalian blastocyst hatches before implantating into the endometrial lining of the womb. Once implanted the embryo will continue its development through the next stages of gastrulation, neurulation, and organogenesis. Gastrulation is the formation of the three germ layers that will form all of the different parts of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leaf Litter
Plant litter (also leaf litter, tree litter, soil litter, litterfall, or duff) is dead plant material (such as leaves, bark, needles, twigs, and cladodes) that has fallen to the ground. This detritus or dead organic material and its constituent nutrients are added to the top layer of soil, commonly known as the litter layer or O-horizon ("O" for "organic"). Litter is an important factor in ecosystem dynamics, as it is indicative of ecological productivity and may be useful in predicting regional nutrient cycling and soil fertility. Characteristics and variability Litterfall is characterized as fresh, undecomposed, and easily recognizable (by species and type) plant debris. This can be anything from leaves, cones, needles, twigs, bark, seeds/nuts, logs, or reproductive organs (e.g. the stamen of flowering plants). Items larger than 2 cm diameter are referred to as coarse litter, while anything smaller is referred to as fine litter or litter. The type of litterfall is m ...

Predation
Predation is a biological interaction in which one organism, the predator, kills and eats another organism, its prey. It is one of a family of common List of feeding behaviours, feeding behaviours that includes parasitism and micropredation (which usually do not kill the Host (biology), host) and parasitoidism (which always does, eventually). It is distinct from Scavenger, scavenging on dead prey, though many predators also scavenge; it overlaps with Herbivore, herbivory, as Seed predation, seed predators and destructive frugivores are predators. Predation behavior varies significantly depending on the organism. Many predators, especially carnivores, have evolved distinct hunting strategy, hunting strategies. Pursuit predation involves the active search for and pursuit of prey, whilst ambush predation, ambush predators instead wait for prey to present an opportunity for capture, and often use stealth or aggressive mimicry. Other predators are opportunism, opportunistic or om ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chilean National Zoo
The Chilean National Zoo (''Zoológico Nacional de Chile'') is a zoo that was founded in 1925 in Santiago, Chile. Located at the foot of San Cristóbal Hill in what is known as the Santiago Metropolitan Park (''Parque Metropolitano de Santiago''), the zoo is home to thousands of animals representing 158 species. Unique exhibits feature Chilean native animals and birds including rare and endangered species.

IUCN
The International Union for Conservation of Nature (IUCN) is an international organization working in the field of nature conservation and sustainable use of natural resources. Founded in 1948, IUCN has become the global authority on the status of the natural world and the measures needed to safeguard it. It is involved in data gathering and Data analysis, analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects.
