Description ( anglais )

fourni par AmphibiaWeb articles
Mantella baroni is a small frog, with adults measuring 22-30 mm in snout-vent length. The head, dorsum, and flanks are solid black. A yellowish rostral stripe is apparent, generally ending past the eye. The front limb and femur are yellow to greenish in appearance, with this coloration continuing up the flanks into a large, rounded flank blotch. These flank blotches will sometimes expand dorsally across the back and connect to the opposite side blotch, resulting in a more yellow dorsum (this is most often seen in M. baroni from the Andringitra region). Hindlimbs (tibia, tarsus, and foot) are orange with irregular black stripes. There are no flashmarks on the lower hindlimbs, in contrast to those of M. madagascariensis. The venter, throat, and limbs are black and marked with a few yellow to greenish, rarely blue blotches. The throat has one circular marking, but may be all black. The iris is black (Glaw and Vences 2007).Mantella baroni was first described by Boulenger (1888). It is a member of the M. cowani species group (Goodman and Benstead 2003). There is a report of hybridization with M. cowani in the wild, at a locality near Antoetra (Andreone et al. 2005).

Distribution and Habitat ( anglais )

fourni par AmphibiaWeb articles
This species is found only in east-central Madagascar, from Fierenana south to Andringitra, at an elevation of 600-1,200m (IUCN 2008). Mantella baroni occupies a number of habitats including swamp forests, semi-arid streambeds, bamboo groves, and streamside forests (Andriantsiferana et al. 2006) In the rainforest it is often found close to rivers and streams (Goodman and Benstead 2003; Glaw and Vences 2007), but it has also been found in slash-and-burn areas away from rainforest (IUCN 2008).

Male M. baroni emit an intense sequence of short, single-click notes, calling during the day from refuges under grass, bushes, and rocks (Glaw and Vences 2007). Mantelline frogs lack amplexus (Glaw and Vences 2007). Females lay eggs on land (Clark et al. 2005). The eggs are unpigmented and always found close to water (Clark et al. 2005). Females can lay up to 130 eggs in one clutch (Clark et al. 2005). When the eggs develop into tadpoles, the tadpoles are washed away by rain into a nearby body of water (Goodman and Benstead 2003).Mantella baroni is an active diurnal forager (Clark et al. 2005). It consumes a greater number of prey, as well as larger prey, than do other species of Mantella (Clark et al. 2006). Adult M. baroni consume various arthropods, with ants contributing the largest percentage of the diet (Odierna et al. 2001). Ingestion of ants, beetles, and mites creates high alkaloid concentrations in the frog’s skin, making it toxic to predators (Odierna et al. 2001). Although ants are the primary prey, the majority of toxins come from mites (Daly et al. 2007). The bright colors of M. baroni are thus aposematic and serve as a warning sign of their toxicity (Clark et al. 2005). The mechanism that the frog uses to sequester these alkaloids is unknown (Clark et al. 2005). Alkaloid composition can vary both temporally and geographically in this species (Daly et al. 2007; Clark et al. 2006).

Mantella baroni ( anglais )

fourni par wikipedia EN

Mantella baroni (often known by its common names, such as Baron's mantella, the variegated golden frog, or the Madagascar poison frog[2]) is a species of small poisonous frog in the family Mantellidae.

The species was first formally described by George Albert Boulenger in 1888, who penned the species' binomial after Richard Baron, an English botanist and missionary to Madagascar, who collected and studied the species.[3]

Distribution, habitat, and conservation status

Like other species in Mantellidae, this taxon is endemic to Madagascar.[4] This family is estimated to have colonized the island of Madagascar 76–87 million years ago, evolving in insular seclusion, and adaptively radiating in geographic range and number of species on the island.[5] Mantellidae are phylogenetically related to Asiatic frogs, and therefore probably represent a dispersal event from Asia.[5]

This is one of approximately 220 frog species (including 15 in Mantella) endemic only to Madagascar.[6] It has a moderately-large elongated geographic range in East-Central Madagascar,[1] inland from the east coast, and spanning north to south, from Fierenana south to Andringitra.[7]

Its natural habitats are subtropical or tropical moist lowland forest, subtropical or tropical moist montane forest, rivers, and degraded former forest. It typically prefers residing at elevations between 600-1200 meters above sea level.[1][7]

Although it has been classified as a Least Concern species by the IUCN as of 2016, due to its relatively wide distribution, population trends are technically unknown, and it may be threatened by several sources of habitat loss. These include anthropogenic encroachment from commercialization and industrialization, timber and logging operations, and agriculture. It appears in CITES Appendix II.[1]

Description

Though only 28–32 mm in length at maturity, this species is one of the largest in the 16-species genus,[8] dwarfed only by some individuals of Mantella viridis.[6] Related Mantella species typically range from 18–31 mm in morphology for adult individuals.[4] Mantella frogs generally exhibit sexual dimorphism, with the females (28–32 mm) of this species being slightly larger than the males (24–28 mm). This difference in size becomes prominent after approximately 10–12 months of age.

Most individuals in this species display specific unique characteristics that distinguish them from other Mantella species, such as a "light rostral line above the eyes" and "tiger-like markings on the hind limbs" of "orange with irregular black stripes", as seen in the images above.[7][8] However, a wide variety of phenotypes exist, which manifest in front limb colors ranging from light greens to vibrant oranges and yellows, and are sometimes mistaken or imported into the international marketplace as Mantella cowanii.[8]

Moreover, the "front limbs and femurs are yellow to greenish in appearance, with this coloration continuing up the flanks into a large, rounded flank blotch",[7] which mirrors the commonplace appearance of the species Mantella madagascariensis, known as the painted mantella. These blotches "contrast with the black dorsum and striking orange and black legs" in both species,[6] making it difficult for distributors, vendors, herpetologists, breeders, collectors, and pet owners to acquire the correct species.[9] The easiest way to differentiate the two species is to note the "sky-blue, horseshoe-shaped marking"[6] present on the throat of the painted mantella, as well as the lack of "flashmarks on the lower hindlimbs"[7] on the Baron's mantella. Due to their similar appearance, the Baron's mantella is sometimes informally called a "painted mantella" as well, despite the painted mantella being a distinct species altogether.[6][9]

As seen in the pictures above, M. baroni demonstrates strong aposomatic features on their front limbs, hind limbs, and rostral line.[8] [6] [10] Similar aposomatic features – such as bright colorations, striking color differentials, and otherwise unconventional patterning – are common to all 16 species of Mantella, to varying levels of veracity (some species of Mantella have weaker toxicity and primarily use bright colors as a form of mimicry).[10] Despite resembling the similarly-small poison dart frogs of Latin America, which also communicate their toxicity to potential predators through aposematism, Mantella species like the Baron's mantella are only distant taxonomic relatives.[10][9] The existence of these similarities between these two families is an example of convergent evolution.[10]

Activity and reproduction

Male M. baroni emit "intense sequences of short, single-click notes during the day"[7] in order to assert their territory or attract females for mating. Females can lay up to 130 unpigmented eggs in a single clutch, and almost always do so near a source of water, into which the resulting tadpoles get washed by rainwater.[7]

Diet, predation, and toxicology

Mantella baroni is a very active forager and can consume a greater number of prey (consisting of large arthropods[7][10]) than any other Mantella species,[7] consisting of large arthropods. While most frog species are nocturnal, the Mantella baroni is a diurnal hunter.[7][10] Its diet consists mainly of ants,[7][10] while also consuming a number of other types of arthropods like beetles, spiders, and mites.

Ingesting mites allows them to secrete high pharmacologically-active alkaloid concentrations in their skin, making them toxic to predators, with their bright colors serving as a warning sign that ingestion could be dangerous and induce sickness.[9][7][10] The intensity of this alkaloid concentration can flux both temporally and geographically,[7] but careless human handling is always discouraged.[8] Human activity may influence the level of Mantella toxicity by polluting the environment, killing its sources of food and limiting an otherwise diversified diet, so remote populations may be more potent.[10]

Herpetologie

Mantella baroni is een kikker uit de familie gouden kikkers (Mantellidae).[2] De soort komt endemisch voor op het Afrikaanse eiland Madagaskar.[3]

Uiterlijke kenmerken

Mantella baroni is met een lichaamslengte van 22 tot 30 millimeter een relatief kleine kikker. De kop, flanken en bovenzijde zijn zwart, de dijen, voorpoten en een gedeelte daarboven geel tot groen. Het achterbeen en de voet is oranje met zwarte strepen, bij sommige exemplaren is de kleur vrijwel zwart. De zwarte onderzijde, ledematen en keel zijn bedekt met gele tot groenblauwe vlekken. Een lichtgele streep loopt vanaf de snuit tot voorbij de bovenzijde van beide zwarte ogen.

Mantella baroni lijkt sterk op M. madagascariensis, die minder veelvuldig voorkomt. M. madagascariensis heeft echter een groen vlekkenpatroon op de kop en bovenzijde.

Gedrag en leefwijze

Mantella baroni brengt vrijwel zijn hele leven op het land door, al blijft hij meestal in de buurt van rivieren en stroompjes. De kikker is een dagactieve jager en eet voornamelijk mieren, maar ook andere geleedpotigen. De felle kleuren van M. baroni zijn een waarschuwing voor predatoren dat zijn huid gif afscheidt, een alkaloïde die hij onttrekt aan mijten, mieren en sommige keversoorten.

Mannetjes laten zich overdag horen door korte, luide klikgeluiden. De kikkers paren in tegenstelling tot de meeste kikkersoorten niet door middel van een amplexus (paaromhelzing). Een broedsel kan tot wel 130 eieren bevatten, die het vrouwtje op het land deponeert. Tijdens het regenseizoen spoelt de regen de uitgekomen kikkervissen naar het water, waar ze zich verder ontwikkelen.

Mantella baroni is endemisch op Madagaskar. Hij komt in het oosten van het eiland voor op een hoogte van 600 tot 1200 meter boven de zeespiegel. Deze kikker komt voor in verschillende habitats, zoals moerassen en subtropische en tropische regenwouden, zowel in gebergten als in de laaglanden.

Status

De soort heeft een groot aanpassingsvermogen en is een talrijke kikkersoort op Madagaskar. Bovendien komt hij voor in een aantal beschermde reservaten, zoals de Nationale parken Ranomafana, Mantadia en Andringitra. M. baroni is derhalve als 'niet bedreigd' (Least Concern) opgenomen op de Rode Lijst van de IUCN. Op de lijst van CITES, een internationale overeenkomst over de handel in dieren en planten, is hij opgenomen in Bijlage II, wat wil zeggen dat voor de export een vergunning moet worden aangevraagd.[1]

Taxonomie

Mantella baroni werd in 1888 voor het eerst geldig gepubliceerd door de zoöloog George Albert Boulenger. Hij vernoemde de kikker naar de Britse botanicus en geoloog Richard Baron (1847-1907), die 35 jaar in Madagaskar heeft gewoond.

Synoniemen
  • Phrynomantis maculatus - Thominot, 1889

Mogelijk is Mantella haraldmeieri ook een synoniem.[1]

Mantella baroni ( portugais )

fourni par wikipedia PT

Mantella baroni é uma espécie de anfíbio da família Mantellidae.

É endémica de Madagáscar.

Os seus habitats naturais são: florestas subtropicais ou tropicais húmidas de baixa altitude, regiões subtropicais ou tropicais húmidas de alta altitude, rios e florestas secundárias altamente degradadas.[1]

É comumente conhecida como mantella-de-Baron, rã-dourada-variegada ou rã-venenosa-de-Madagascar. A espécie foi descrita em 1888 por George Albert Boulenger, que a batizou com o nome de seu coletor, Richard Baron. Foi classificada como uma espécie pouco preocupante pela União Internacional para a Conservação da Natureza devido à sua distribuição relativamente ampla, mas está ameaçada pela perda de habitat[1]. A dieta da rã inclui ácaros, que fazem com que ela acumule alta concentração de alcaloides na pele, tornando-a tóxica. As cores brilhantes podem servir como um sinal de alerta para predadores potenciais da toxicidade da rã.
