Durrell's Vontsira
Durrell's vontsira (''Salanoia durrelli'') is a small, reddish-brown, fox-like mammal native to the island of Madagascar. Discovered in 2004, it lives only in the biodiverse wetlands of Lake Alaotra. Durrell's vontsira belongs to the family Eupleridae, a group of meat-eating, cat- or fox-like mammals (of the order Carnivora) found only on Madagascar. The species is closely related to the brown-tailed mongoose (''Salanoia concolor''), with which it forms the genus ''Salanoia''. The two are genetically similar, but morphologically distinct, and ''S. durrelli'' was described as a new species in 2010. A small, reddish-brown carnivore, ''Salanoia durrelli'' is characterized by broad feet with prominent pads, reddish-buff underparts, and broad, robust teeth, among other differences from the brown-tailed mongoose. In the only two weighed specimens, body mass was . It is a marsh-dwelling animal that may feed on crustaceans and mollusks. The Lake Alaotra area is a threatened ec ...

Mammal
Mammals () are a group of vertebrate animals constituting the class Mammalia (), characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles (including birds) from which they diverged in the Carboniferous, over 300 million years ago. Around 6,400 extant species of mammals have been described divided into 29 orders. The largest orders, in terms of number of species, are the rodents, bats, and Eulipotyphla (hedgehogs, moles, shrews, and others). The next three are the Primates (including humans, apes, monkeys, and others), the Artiodactyla ( cetaceans and even-toed ungulates), and the Carnivora (cats, dogs, seals, and others). In terms of cladistics, which reflects evolutionary history, mammals are the only living members of the Synapsida (synapsids); this clade, together with Saur ...

Nature Heritage
Nature, in the broadest sense, is the physics, physical world or universe. "Nature" can refer to the phenomenon, phenomena of the physical world, and also to life in general. The study of nature is a large, if not the only, part of science. Although humans are part of nature, human activity is often understood as a separate category from other natural phenomena. The word ''nature'' is borrowed from the Old French ''nature'' and is derived from the Latin word ''natura'', or "essential qualities, innate disposition", and in ancient times, literally meant "birth". In ancient philosophy, ''natura'' is mostly used as the Latin translation of the Greek word ''physis'' (φύσις), which originally related to the intrinsic characteristics of plants, animals, and other features of the world to develop of their own accord. The concept of nature as a whole, the physical universe, is one of several expansions of the original notion; it began with certain core applications of the word ...

Galidia Olivacea Geoffroy
The ring-tailed vontsira, locally still known as the ring-tailed mongoose (''Galidia elegans'') is a euplerid in the subfamily Galidiinae, a carnivoran native to Madagascar. It is the only species in genus ''Galidia''. Classification and etymology There is much disagreement about the placement of Madagascar's carnivores, including the ring-tailed vontsira, within the phylogenetic tree. A 2003 study reported evidence that the Malagasy Carnivora evolved from a single herpestid ancestor. A monotypic genus, ''Galidia'' literally means "little weasel", being a diminutive form of (, "weasel" in ancient Greek). Its local common name is ''vontsira mena'', ‘red '' vontsira''’ in Malagasy. Description The ring-tailed vontsira is relatively small but is the largest member of the subfamily Galidiinae Galidiinae is a subfamily of carnivorans that is restricted to Madagascar and includes six species classified into four genera.

Hapalemur Griseus
The eastern lesser bamboo lemur (''Hapalemur griseus''), also known as the gray bamboo lemur, the gray gentle lemur, and the Mahajanga lemur is a small lemur endemic to Madagascar, with three known subspecies. As its name suggests, the eastern lesser bamboo lemur feeds mainly on bamboo. The lemurs of the genus ''Hapalemur'' have more manual dexterity and hand–eye coordination than most lemurs. They are vertical climbers and jump from stalk to stalk in thick bamboo forests. Subspecies Eastern lesser bamboo lemur The eastern lesser bamboo lemur (''Hapalemur griseus griseus''), also known as the gray bamboo lemur, eastern gray bamboo lemur, or gray gentle lemur, was the original species described in 1795 by Johann Heinrich Friedrich Link. It is grey in colour, sometimes with a red patch on its head. It averages in length with a tail of . Based on data from more than one hundred transect surveys which took place between 2004 and 2009, the population is estimated to be declining ...

Hapalemur Alaotrensis
The Lac Alaotra bamboo lemur (''Hapalemur alaotrensis''), also known as the Lac Alaotra gentle lemur, Alaotran bamboo lemur, Alaotran gentle lemur, Alaotra reed lemur, or locally as the ', is a bamboo lemur. It is endemic to the reed beds in and around Lac Alaotra, in northeast Madagascar. It is about long, with a similar length tail, and is a brownish-gray colour. It is the only bamboo lemur to live in and feed on Cyperus papyrus, papyrus reeds, and other reeds and grasses, and some authorities argue that it should be regarded as a subspecies of the eastern lesser bamboo lemur (''Hapalemur griseus''). The population of this lemur has been declining because of habitat destruction and the International Union for Conservation of Nature has rated it as being "critically endangered". Taxonomy The classification of the'' bandro'' is disputed, with some classifying it as a subspecies of ''Hapalemur griseus'', while others see it as a separate species.

Adaptation
In biology, adaptation has three related meanings. Firstly, it is the dynamic evolutionary process of natural selection that fits organisms to their environment, enhancing their evolutionary fitness. Secondly, it is a state reached by the population during that process. Thirdly, it is a phenotypic trait or adaptive trait, with a functional role in each individual organism, that is maintained and has evolved through natural selection. Historically, adaptation has been described from the time of the ancient Greek philosophers such as Empedocles and Aristotle. In 18th and 19th century natural theology, adaptation was taken as evidence for the existence of a deity. Charles Darwin proposed instead that it was explained by natural selection. Adaptation is related to biological fitness, which governs the rate of evolution as measured by change in allele frequencies. Often, two or more species co-adapt and co-evolve as they develop adaptations that interlock with those of the oth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mitochondrial DNA
Mitochondrial DNA (mtDNA or mDNA) is the DNA located in mitochondria, cellular organelles within eukaryotic cells that convert chemical energy from food into a form that cells can use, such as adenosine triphosphate (ATP). Mitochondrial DNA is only a small portion of the DNA in a eukaryotic cell; most of the DNA can be found in the cell nucleus and, in plants and algae, also in plastids such as chloroplasts. Human mitochondrial DNA was the first significant part of the human genome to be sequenced. This sequencing revealed that the human mtDNA includes 16,569 base pairs and encodes 13 proteins. Since animal mtDNA evolves faster than nuclear genetic markers, it represents a mainstay of phylogenetics and evolutionary biology. It also permits an examination of the relatedness of populations, and so has become important in anthropology and biogeography. Origin Nuclear and mitochondrial DNA are thought to be of separate evolutionary origin, with the mtDNA being derived ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Morphology (anatomy)
Morphology is a branch of biology dealing with the study of the form and structure of organisms and their specific structural features. This includes aspects of the outward appearance (shape, structure, colour, pattern, size), i.e. external morphology (or eidonomy), as well as the form and structure of the internal parts like bones and organs, i.e. internal morphology (or anatomy). This is in contrast to physiology, which deals primarily with function. Morphology is a branch of life science dealing with the study of gross structure of an organism or taxon and its component parts. History The etymology of the word "morphology" is from the Ancient Greek (), meaning "form", and (), meaning "word, study, research". While the concept of form in biology, opposed to function, dates back to Aristotle (see Aristotle's biology), the field of morphology was developed by Johann Wolfgang von Goethe (1790) and independently by the German anatomist and physiologist Karl Friedrich Burdach ...

Galidiinae
Galidiinae is a subfamily of carnivorans that is restricted to Madagascar and includes six species classified into four genera. Together with the three other species of indigenous Malagasy carnivorans, including the fossa, they are currently classified in the family Eupleridae within the suborder Feliformia.Wozencraft, 2005, pp. 560–561 Galidiinae are the smallest of the Malagasy carnivorans, generally weighing about 600 to 900 g. They are agile, short-legged animals with long, bushy ringed tails.Yoder and Flynn, 2003 They closely resemble the mongooses (family Herpestidae) of continental Africa and southern Eurasia, with which they were classified until 2006, and accordingly they are said to be "mongoose-like" or even described as "Malagasy mongooses". The Malagasy name vontsira is a common name or alias for many species. Taxonomy The relationship of galidiines to other carnivorans has historically been controversial. Up to the middle of the 20th century, all smaller felifor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malagasy Language
Malagasy (; ) is an Austronesian language and the national language of Madagascar. Malagasy is the westernmost Malayo-Polynesian language, brought to Madagascar by the settlement of Austronesian peoples from the Sunda islands around the 5th century AD. The Malagasy language is one of the Barito languages and is most closely related to the Ma'anyan language, still spoken on Borneo to this day. Malagasy also includes numerous Malay loanwords, from the time of the early Austronesian settlement and trading between Madagascar and the Sunda Islands. After c. 1000 AD, Malagasy incorporated numerous Bantu and Arabic loanwords, brought over by traders and new settlers. Malagasy is spoken by around 25 million people in Madagascar and the Comoros. Most people in Madagascar speak it as a first language, as do some people of Malagasy descent elsewhere. Malagasy is divided between two main dialect groups; Eastern and Western. The central plateau of the island, where the capital Antananarivo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Common Name
In biology, a common name of a taxon or organism (also known as a vernacular name, English name, colloquial name, country name, popular name, or farmer's name) is a name that is based on the normal language of everyday life; and is often contrasted with the scientific name for the same organism, which is Latinized. A common name is sometimes frequently used, but that is not always the case. In chemistry, IUPAC defines a common name as one that, although it unambiguously defines a chemical, does not follow the current systematic naming convention, such as acetone, systematically 2-propanone, while a vernacular name describes one used in a lab, trade or industry that does not unambiguously describe a single chemical, such as copper sulfate, which may refer to either copper(I) sulfate or copper(II) sulfate. Sometimes common names are created by authorities on one particular subject, in an attempt to make it possible for members of the general public (including such interested par ...

Gerald Durrell
Gerald Malcolm Durrell, (7 January 1925 – 30 January 1995) was a British naturalist, writer, zookeeper, conservationist, and television presenter. He founded the Durrell Wildlife Conservation Trust and the Jersey Zoo on the Channel Island of Jersey in 1959. He wrote approximately forty books, mainly about his life as an animal collector and enthusiast, the most famous being ''My Family and Other Animals'' (1956). Those memoirs of his family's years living in Greece were adapted into two television series (''My Family and Other Animals'', 1987, and ''The Durrells'', 2016–2019) and one television film (''My Family and Other Animals'', 2005). He was the youngest brother of novelist Lawrence Durrell. Early life and education Durrell was born in Jamshedpur, British India, on 7 January 1925. He was the fifth and youngest child (an elder sister having died in infancy) of Louisa Florence Dixie and Lawrence Samuel Durrell, both of whom were born in India of English and Irish ...
