Mantellidae Boophis Bottae Facing
The Mantellidae are a family of the order Anura. These frogs are endemic to the islands of Madagascar and Mayotte. Systematics The family Mantellidae is composed of three extremely ecologically diverse groups of frogs, divided into three subfamilies: the Mantellinae Laurent, 1946 are typically terrestrial or semi-aquatic frogs; the Laliostominae Vences & Glaw, 2001 are terrestrial, typically fairly large-sized frogs; and the Boophinae Vences & Glaw, 2001 are arboreal tree frogs. Apart from the genera assigned to the three subfamilies, the placement of ''Tsingymantis'' Glaw, Hoegg & Vences, 2006 is still uncertain. As of 22 September 2022, 237 species are recognized in this family. DNA barcoding research has shown however that more than 100 distinct genetic lineages remain taxonomically undescribed. Evolution and island biogeography The Mantellidae are Madagascar's most diverse frog family. It has been shown that there is a negative correlation between body size and sp ...

Dispersal (ecology)
Biological dispersal refers to both the movement of individuals (animals, plants, fungi, bacteria, etc.) from their birth site to their breeding site ('natal dispersal'), as well as the movement from one breeding site to another ('breeding dispersal'). Dispersal is also used to describe the movement of propagules such as seeds and spores. Technically, dispersal is defined as any movement that has the potential to lead to gene flow. The act of dispersal involves three phases: departure, transfer, settlement and there are different fitness costs and benefits associated with each of these phases. Through simply moving from one habitat Landscape ecology#Patch and mosaic, patch to another, the dispersal of an individual has consequences not only for individual fitness (biology), fitness, but also for population dynamics, population genetics, and species distribution. Understanding dispersal and the consequences both for evolutionary strategies at a species level, and for processes a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Boophis
''Boophis'' is the only genus in the mantellid frog subfamily Boophinae. They are commonly known as bright-eyed or skeleton frogs. They show typical 'tree frog' traits, and are a good example of convergent evolution with morphologically similar species in the families Hylidae and Rhacophoridae, among others. This genus can only be found on Madagascar and Mayotte Island ( Comoros). Taxonomy The genus ''Boophis'' was described by Johann Jakob von Tschudi in 1838. It was originally considered a member of the African-Asian family Rhacophoridae, but was moved to the family Mantellidae in 2001, into its own subfamily, Boophinae Vences & Glaw, 2001. Morphology ''Boophis'' are arboreal frogs, exhibiting many traits that define 'tree frogs', such as expanded toe discs, long hindlimbs, and large eyes. ''Boophis'' are especially characterised by bright colouration of the iris, which is typically intricately patterned towards its inside, and often green or blue, but occasionally also ...

Mantella
''Mantella'' (also known as golden frogs or Malagasy poison frogs) are a prominent genus of aposematic frogs in the family Mantellidae, endemic to the island of Madagascar. Members of ''Mantella'' are diurnal and terrestrial, with bright aposematic coloration or cryptic markings. Natural history ''Mantella'' are an example of convergent evolution—the independent evolution of a similar trait with species of a different lineage—with the Latin American family Dendrobatidae in size, appearance, and some behavioral characteristics. During the description of the first specimens from 1866 to 1872, Alfred Grandidier described both the brown mantella (''Mantella betsileo'') and Malagasy mantella (''Mantella madagascariensis'') and placed them within the genus ''Dendrobates'' based on their close resemblance. This placement was heavily debated until 1882, when George Albert Boulenger created the genus ''Mantella'' after describing both Cowan's mantella (''Mantella cowanii'') and ...

Exotic Pet
An exotic pet is a pet which is relatively rare or unusual to keep, or is generally thought of as a wild species rather than as a domesticated pet. The definition varies by culture, location, and over time—as animals become firmly enough established in the world of animal fancy, they may no longer be considered ''exotic''. Definitions The definition is an evolving one; some rodents, reptiles, and amphibians have become firmly enough established in the world of animal fancy to no longer be considered exotic. Sometimes any unique or wild-looking pet (including common domestic animals such as the ferret and the rat) is considered an exotic pet. "Exotic" often refers to a species which is not native or indigenous to the owner's locale, and "pet" is a companion animal living with people. However, many use the term to include native species as well (e.g., snakes may sometimes be considered exotic as pets even in places where they are found in the wild). The international organi ...

Amplexus
Amplexus (Latin "embrace") is a type of mating behavior exhibited by some externally fertilizing species (chiefly amphibians and horseshoe crabs) in which a male grasps a female with his front legs as part of the mating process, and at the same time or with some time delay, he fertilizes the eggs, as they are released from the female's body. In amphibians, females may be grasped by the head, waist, or armpits, and the type of amplexus is characteristic of some taxonomic groups. Amplexus involves direct contact between male and female, distinguished from other forms of external fertilization, such as broadcast spawning, where sperm and eggs are freely shed into water without direct contact by individuals. In order for amplexus to be initiated, male frogs must first find a mate by attracting one through calls, typically in the evening. Once a male has successfully attracted a mate, the process of amplexus begins, while the unsuccessful males are forced to continue their search fo ...

Nidicolous
In biology, nidifugous ( , ) organisms are those that leave the nest shortly after hatching or birth. The term is derived from Latin ''nidus'' for "nest" and ''fugere'', meaning "to flee". The terminology is most often used to describe birds and was introduced by Lorenz Oken in 1816. The chicks of birds in many families, such as the waders, waterfowl, and gamebirds, are usually nidifugous. The opposite of nidifugous organisms are nidicolous ( ; from Latin ''nidus'' "nest" and ''-colus'' "inhabiting") organisms; a nidicolous organism is one which stays at its birthplace for a long time because it depends on its parents for food, protection, and the learning of survival skills. Examples of nidicolous species include mammals and many species of birds. During the life span, the brain of a nidicolous animal expands 8–10 times its initial size; in nidifugous animals, it expands from 1.5 to 2.5 times.

Direct Development
Marine larval ecology is the study of the factors influencing dispersing larvae, which many marine invertebrates and fishes have. Marine animals with a larva typically release many larvae into the water column, where the larvae develop before metamorphosing into adults. Marine larvae can disperse over long distances, although determining the actual distance is challenging, because of their size and the lack of a good tracking method. Knowing dispersal distances is important for managing fisheries, effectively designing marine reserves, and controlling invasive species. Theories on the evolution of a biphasic life history Larval dispersal is one of the most important topics in marine ecology, today. Many marine invertebrates and many fishes have a bi-phasic life cycle with a pelagic larva or pelagic eggs that can be transported over long distances, and a demersal or benthic adult. There are several theories behind why these organisms have evolved this biphasic life history: *Larva ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
