Conservation Status ( İngilizce )

Animal Diversity Web tarafından sağlandı

Atlantic bamboo rats are naturally rare; a study in Rio Grande do Sul State reports a density of 4.28 individuals per km^2. However, due to their wide distribution and large population, Atlantic bamboo rats are listed as "least concern" on IUCN Red List of Threatened Species. Atlantic bamboo rats are locally threatened in Minas Gerais State, Brazil due to habitat destruction largely due to logging.

US Federal List: no special status

CITES: no special status

Behavior ( İngilizce )

Animal Diversity Web tarafından sağlandı

Atlantic bamboo rats use vocalizations to defend resources and warn conspecifics of potential threats. Often performing vocalizations after dark, they sit on bamboo culms and thrust their head forward with each call. They remain secluded amongst the bamboo leaves, rarely exposing their position. During alarm calls, they call once and run to an area of greater cover, and continue calling for several minutes. When conspecifics hear a call, they escape to areas with greater cover and counter-call.

Atlantic bamboo rats are important seed dispersers of various bamboo species. In addition, the manner by which they feed on bamboo is thought to be beneficial to the overall health of bamboo stands in which they reside. They may also be an important food source for brown capuchins, and although it has not been documented, Atlantic bamboo rats are likely host to a number of endo- and ectoparasites as well.

Habitat ( İngilizce )

Animal Diversity Web tarafından sağlandı

Atlantic bamboo rats are found in moist tropical forests, particularly bamboo thickets located near water. They build arboreal nests in native giant climbing bamboo (Guadua angustifoila), as well as in introduced species of bamboo, such as several Phyllostachys spp. and Chinese bamboo (Bambusa tuldoides). Native Guadua stands are rare in southeastern and southern Brazil due to deforestation practices. However, with the introduction of Phyllostachys spp. and B. tuldoides, Atlantic bamboo rats are able to re-inhabit parts of their native range.

Morphology ( İngilizce )

Animal Diversity Web tarafından sağlandı

Atlantic bamboo rats are large rodents, ranging in size from 230 to 347 cm long, with a long tail of 300 to 420 cm long. They weigh between 350 to 600 g. Their dorsal pelage is olive-green to brown-orange with orange ventral pelage and white patches on their throat and chest. They have a square-like snout, gray cheeks, long whiskers and white lips. Thick fur covers the base of their tail, which tapers to a small tuft of dark-brown distal hairs. They have four long digits, an elongated and broadened third and forth digit separated by a gap, and flat nails, which allow them to have a firm grip on bamboo culms. The dental formula for members of the family Echimayidae is 1/1 0/0 1/1 3/3 for a total of 20 teeth. Atlantic bamboo rats have flat-crowned cheek teeth and differ from other Dactylomys spp. by having narrow enamel ridges present on their upper cheek teeth, as well as an absence of a constricted palate. Atlantic bamboo rats are sexually dimorphic. Although coloration is similar between sexes, males are generally larger than females. However, a monogamous population inhabiting Itapuã State Park in southern Brazil showed no sexual dimorphism.

Range mass: 350 to 600 g.

Range length: 230 to 347 cm.

Other Physical Features: endothermic ; homoiothermic; bilateral symmetry

Sexual Dimorphism: male larger

Brown capuchins are thought to be potential predators of Atlantic bamboo rats. They have been observed foraging among bamboo stands and are known to eat rodents. When capuchins forage in thickets inhabited by Atlantic bamboo rats, rats quickly find shelter amongst the bases of bamboo clumps. After capuchins leave, rat carcasses with the head and thorax missing are often found at the base of bamboo stands. However, actual capture and feeding by brown capuchins on Atlantic bamboo rats has not been documented.

Known Predators:

  • brown capuchin (Cebus apella)

Reproduction ( İngilizce )

Animal Diversity Web tarafından sağlandı

Direct confirmation of polygny in Atlantic bamboo rats has not been documented in the wild nor have any genetic analyses on allelic contribution from either parent been conducted in order to determine polygyny or polyandry. However, physical characteristics and social patterns associated with polygyny have been reported in Atlantic bamboo rats. For example, males are larger than females and have larger home ranges, which may overlap the home ranges of several females. Stallings et al. (1994) found that when numerous bamboo patches were located close together, males were able to obtain access to multiple females, suggesting polygyny. However, in areas with low population densities, females are restricted to small, widely-spaced home ranges, which decreases the probability of males to acquire more than one mate. Under these situations, Atlantic bamboo rats are observed to be monogamous, living in mating pairs, with no co-occurrences of same-sex adults in the same bamboo patch.

Mating System: monogamous ; polygynous

Very little is known on the general behavior of the Atlantic bamboo rat during reproduction. They breed year round, yielding between 1 and 3 young per liter, with an average of 1.7 young per litter. Olmos et al (1993) found a deceased 600 g female with two near-term fetuses, both weighing approximately 20% of the mother’s weight. This suggests that neonate Atlantic bamboo rats require large demands of food and energy from their mother.

Range number of offspring: 1 to 3.

Average number of offspring: 1.7.

Key Reproductive Features: iteroparous ; gonochoric/gonochoristic/dioecious (sexes separate); sexual ; viviparous

In Itapuã State Park, Brazil, monogamous mated males showed direct parental behavior similar to that of females, including grooming, huddling, and food provisioning. Furthermore, both males and females performed indirect parental behavior, such as alarm calls and nest building. In the event of a death or disappearance to one of the parents, the surviving parent (male or female) remains with the young, indicating prolonged parental care. In patchy arboreal habitats, biparental care is advantageous for Atlantic bamboo rats, as it reduces the risks of young falling from trees and depredation when moving amongst exposed branches.

Parental Investment: male parental care ; female parental care ; pre-hatching/birth (Provisioning: Female, Protecting: Female); pre-weaning/fledging (Provisioning: Male, Female, Protecting: Male, Female); pre-independence (Provisioning: Male, Female, Protecting: Male, Female)

Bambus-Fingerratte ( Almanca )

wikipedia DE tarafından sağlandı

Die Bambus-Fingerratte (Kannabateomys amblyonyx) ist ein Nagetier in der Familie der Stachelratten. Die Art bildet die monotypische Gattung Kannabateomys.[1]

Merkmale

Im Gegensatz zu vielen anderen Stachelratten besitzt die Bambus-Fingerratte ein weiches Fell, ohne Borsten oder Stacheln. Die Beschreibung der Fellfarbe variiert zwischen den vorhandenen Abhandlungen. Laut Nowak (1999) dominieren oberseits gelbbraune Farbtöne mit einer orangenen Schattierung, während die Unterseite hellbraun bis weiß ist.[2] Dagegen beschreiben Eisenberg & Redford (1992) die Fellfarbe auf der Rückenmitte als agouti graubraun, auf den Körperseiten als rotbraun sowie auf dem Bauch und an den Seiten des Gesichtes als rosa.[3] Die Schnauze ist durch eine annähernd viereckige Form und durch lange Vibrissen gekennzeichnet.[4] Typisch ist weiterhin der an der Basis gut behaarte Schwanz, der im mittleren Bereich nur mit kurzen Haaren bedeckt ist und in einer pinselartigen Quaste endet.[3]

Die Bambus-Fingerratte erreicht eine Kopf-Rumpf-Länge von 23 bis 34,7 cm, eine Schwanzlänge von 30 bis 42 cm sowie ein Gewicht von 350 bis 570 g. Der deutsche Name bezieht sich auf die lange und breite Form des dritten und vierten Fingers sowie der dritten und vierten Zehe. Alle Finger und Zehen besitzen flache Nägel. Weitere Unterschiede zu den nahe verwandten Arten der Gattung Dactylomys gibt es im Aufbau des Zahnschmelzes.[2]

Verbreitung

Dieses Nagetier lebt im Südosten Brasiliens und in angrenzenden Bereichen Paraguays, Uruguays sowie Argentiniens. Als Habitat dienen Wälder mit einem Unterwuchs aus Bambus in der Nähe des Atlantiks, tropische und subtropische Regenwälder, Lorbeerwälder, Galeriewälder und kleinere Gebiete, die mit Bambus bedeckt sind.[5]

Lebensweise

Die Bambus-Fingerratte wird meist einzeln oder in Paaren angetroffen. Die Individuen etablieren ein Revier, wobei sich Reviere unterschiedlicher Geschlechter überlappen. Als Nahrung dienen Blätter und junge Triebe von Bambuspflanzen sowie von anderen Gewächsen.[5] Die Tiere klettern überwiegend in Bäumen oder im Bambusgestrüpp und bauen ein größeres Nest im Geäst.[4]

Dieses Nagetier ist hauptsächlich von der Abend- bis zur Morgendämmerung aktiv, kann jedoch vereinzelt am Tage auf Nahrungssuche gehen. Für die Art wird allgemein eine monogame Fortpflanzung angegeben. Da im Revier eines Männchens mehrere Weibchen vorkommen ist eine polygyne Fortpflanzung nicht ganz auszuschließen. Die Paarungsbereitschaft des Weibchens ist an keine Jahreszeit gebunden und pro Wurf kommen ein bis drei Jungtiere vor.[4] Die Aufzucht der Nachkommen erfolgt durch Weibchen und Männchen gemeinsam.[5]

Die Bambus-Fingerratte wird vermutlich vom Haubenkapuziner (Sapajus apella) gejagt, obwohl eine Tötung noch nicht beobachtet wurde.[4]

Status

Gebietsweise können Waldrodungen, Brände oder freilaufende Hunde eine Bedrohung für die Bambus-Fingerratte darstellen. Der Gesamtbestand gilt laut IUCN als nicht gefährdet (Least Concern).[5]

Atlantic bamboo rat ( İngilizce )

wikipedia EN tarafından sağlandı

The Atlantic bamboo rat (Kannabateomys amblyonyx), or southern bamboo rat, is a spiny rat species found in humid tropical forests in Argentina, Brazil and Paraguay. It is the only member of the genus Kannabateomys.[2]

Description

The Atlantic bamboo rat can reach a head-and-body length of 25 cm (9.8 in) with a tail of 32 cm (12.6 in). Its weight is about 475 g (1 lb). The pelage is the typical agouti brown-to-grey colour of many rodents, grading to chestnut on the flanks. The chin and underparts are white tinged with reddish brown. The first 6 cm (2.4 in) of the tail are well-haired but the rest is sparsely haired. There is a distinct tuft of hairs at the tip. When fully grown, this bamboo rat with its long tail is unlikely to be mistaken for any other species.[3]

Etymology

The genus name Kannabateomys derives from the three ancient greek words κάννα (kánna), meaning "reed, cane", βατέω (batéō), meaning "to mount", and μῦς (mûs), meaning "mouse, rat".[4][5][6]

The species name amblyonyx derives from the two ancient greek words ἀμβλύς (amblús), meaning "blunt, not sharp", and ὄνυξ (ónux), meaning "claw, fingernail".[4][5]

Distribution and habitat

This species is native to South America, where its range includes southeastern Brazil, eastern Paraguay and northeastern Argentina. Typical habitat is moist forests near water with dense understorey of bamboos. It is particularly associated with the giant bamboo Guadua angustifolia, which forms thickets.[7]

Ecology

The Atlantic bamboo rat is nocturnal and is highly arboreal, scrambling around in trees and bamboos, especially near water. The home range is about 1,000 m2 (1,200 sq yd). When alarmed it issues loud squeals.[3] It probably feeds on grasses, leaves, shoots, fruits and tubers.[8]

Phylogeny

Kannabateomys is a member of the Echimyini clade of arboreal Echimyidae rodents. Its closest relatives are Dactylomys and Olallamys. These South American bamboo rats share unique features and are grouped under the informal clade name of "Dactylomyines".[9] The dactylomyines are the sister genera to Diplomys and Santamartamys. All these taxa are closely related to the genera Echimys, Phyllomys, Makalata, Pattonomys, and Toromys. In turn, these genera share phylogenetic affinities with the clade containing Lonchothrix and Mesomys, and with Isothrix.[10]

The cladogram has been reconstructed from mitochondrial and nuclear DNA characters.[11][12][13][14][15][16][17][18][10]

Status

K. amblyonyx is not a common species. In the state of Rio Grande do Sul in Brazil, for example, it has been recorded as having a density of just over four individuals per square kilometre. As a nocturnal animal it is seldom seen, but it has an extensive range and is presumed to have a large total population. In some places, such as in the state of Minas Gerais in Brazil, it is threatened locally by forest clearance, but other specific threats have not been identified and the International Union for Conservation of Nature has rated its conservation status as "least concern".[1]

Kannabateomys amblyonyx ( İtalyanca )

wikipedia IT tarafından sağlandı

Kannabateomys amblyonyx (Wagner, 1845) è un roditore della famiglia degli Echimiidi, unica specie del genere Kannabateomys (Jentink, 1891), diffuso nell'America meridionale.[1][2]

Descrizione

Dimensioni

Roditore di grandi dimensioni, con la lunghezza della testa e del corpo tra 230 e 347 mm, la lunghezza della coda tra 300 e 420 mm, la lunghezza del piede tra 45 e 57 mm, la lunghezza delle orecchie tra 16 e 27 mm e un peso fino a 570 g.[3]

Caratteristiche craniche e dentarie

Il cranio presenta un rostro corto e largo, la regione inter-orbitale è ampia, con i margini rialzati che si estendono posteriormente. il palato è stretto, i fori sono piccoli. I denti masticatori hanno la corona bassa, hanno quattro radici, sono notevolmente larghi e le file sono disposte parallelamente tra loro.

Sono caratterizzati dalla seguente formula dentaria:

3 1 0 1 1 0 1 3 3 1 0 1 1 0 1 3 Totale: 20 1.Incisivi; 2.Canini; 3.Premolari; 4.Molari;

Aspetto

La pelliccia è lunga e soffice. Le parti dorsali variano dall'olivastro al fulvo finemente striate di nero, i fianchi sono più fulvi, mentre le parti ventrali sono arancioni con dei riflessi bianchi sulla gola ed il petto. La testa è grande ed ottusa, le vibrisse sono lunghe, le guance sono grigiastre mentre le labbra sono bianche. Le orecchie sono relativamente corte. Le zampe hanno tutte lunghe dita munite di unghie, quelle anteriori ne hanno quattro, con le due centrali ampiamente separate dalle due esterne. I piedi sono lunghi. La coda è molto più lunga della testa e del corpo, è robusta, affusolata, ricoperta di peluria marrone scura sopra e bianca sotto e all'estremità, dove talvolta è presente un ciuffo di peli marroni scuri. Il cariotipo è 2n=98 FN=126.

Biologia

Comportamento

È una specie arboricola che vive solitariamente o in coppie. Le cure parentali di entrambi i genitori, l'allontanamento ritardato dei giovani, l'assenza di dimorfismo sessuale e la sovrapposizione dei raggi d'azione dei due sessi suggeriscono una monogamia. Quando minacciata emette forti squittii.

Alimentazione

Si nutre di germogli e foglie di bambù e altre piante.

Distribuzione e habitat

Questa specie è diffusa nel Paraguay orientale, provincia argentina nord-orientale di Misiones e negli stati brasiliani sud-orientali di Paranà, Rio de Janeiro, Rio Grande do Sul, Santa Catarina e San Paolo.

Vive nei boschi di Bambù, particolarmente lungo corsi d'acqua, nelle foreste pluviali e nelle foreste a galleria umide.

Stato di conservazione

La IUCN Red List, considerato il vasto areale e la popolazione presumibilmente numerosa, classifica K.amblyonyx come specie a rischio minimo (LC).[1]

Kannabateomys amblyonyx ( Portekizce )

wikipedia PT tarafından sağlandı

O rato-da-taquara[2] (nome científico: Kannabateomys amblyonyx), é um mamífero roedor da família dos equimídeos (Echimydae). É o único membro do gênero Kannabateomys.[3]

Descrição

O rato-da-taquara pode atingir um comprimento de cabeça e corpo de 25 centímetros (9,8 polegadas) com uma cauda de 32 centímetros (12,6 polegadas). Seu peso é de cerca de 475 gramas (1 libra). A pelagem é de cor marrom-acinzentada típica de muitos roedores, graduando-se a castanha nos flancos. O queixo e as partes inferiores são brancos tingidos de marrom avermelhado. Os primeiros 6 centímetros (2,4 polegadas) da cauda são bem peludos, mas o resto é esparsamente peludo. Há um tufo distinto de pelos na ponta. Quando totalmente crescido, é improvável que este rato-da-taquara com sua cauda longa seja confundido com qualquer outra espécie.[4]

Etimologia

O nome do gênero Kannabateomys deriva das três palavras gregas antigas: κάννα (kánna), que significa "junco, cana", βατέω (batéō), que significa "montar", e μῦς (mûs), que significa "rato".[5] O nome específico amblyonyx deriva das duas palavras gregas antigas: ἀμβλύς (amblús), que significa "romba, não afiada", e ὄνυξ (ónux), que significa "garra, unha".[6][7]

Distribuição e habitat

O rato-da-taquara é nativa da América do Sul, onde sua distribuição inclui sudeste do Brasil, leste do Paraguai e nordeste da Argentina. O habitat típico são florestas úmidas perto da água com sub-bosque denso de bambus. É particularmente associado ao bambu-gigante (Guadua angustifolia), que forma moitas.[8]

Ecologia

O rato-da-taquara é noturno e altamente arborícola, rastejando em árvores e bambus, especialmente perto da água. A área de residência é de cerca de mil metros quadrados (1 200 jardas quadradas). Quando alarmado, emite guinchos altos.[4] Provavelmente se alimenta de gramíneas, folhas, brotos, frutas e tubérculos.[9]

Filogenia

Kannabateomys é um membro do clado Echimyini de roedores arborícolas equimídeos (Echimyidae). Seus parentes mais próximos são Dactylomys e Olallamys. Esses roedores sul-americanos compartilham características únicas e são agrupados sob o nome informal do clado de "Dactylomyines".[10] Os dactylomyines são os gêneros irmãos de Diplomys e Santamartamys. Todos esses táxons estão intimamente relacionados aos gêneros Echimys, Phyllomys, Makalata, Pattonomys e Toromys. Por sua vez, esses gêneros compartilham afinidades filogenéticas com o clado contendo Lonchothrix e Mesomys, e com Isothrix.[11]

Conservação

A União Internacional para a Conservação da Natureza (UICN / IUCN) avaliou em sua Lista Vermelha o rato-da-taquara como sendo de menor preocupação.[1] Em 2005, foi listada como criticamente em perigo na Lista de espécies ameaçadas de extinção do Estado do Espírito Santo;[12] em 2010, sob a rubrica de dados insuficientes da Lista de Ameaça de Flora e Fauna do Estado do Paraná;[13] em 2014, sob a rubrica de dados insuficientes na Lista de espécies de flora e de fauna de extinção do estado de São Paulo;[14] e em 2018, sob a rubrica de "dados insuficientes" na Lista Vermelha do Livro Vermelho da Fauna Brasileira Ameaçada de Extinção do Instituto Chico Mendes de Conservação da Biodiversidade (ICMBio).[15][16]

Kannabateomys amblyonyx[2] är en däggdjursart som först beskrevs av Wagner 1845. Kannabateomys amblyonyx är ensam i släktet Kannabateomys som ingår i familjen lansråttor.[3][4] IUCN kategoriserar arten globalt som livskraftig.[1]

Inga underarter finns listade i Catalogue of Life.[3] Wilson & Reeder (2005) skiljer mellan två underarter.[5]

Denna gnagare förekommer i södra Brasilien samt i angränsande regioner av östra Paraguay och nordöstra Argentina. Arten vistas i fuktiga tropiska skogar och i områden med bambu nära vattenansamlingar. I bergstrakter når Kannabateomys amblyonyx 1000 meter över havet.[1]

Individerna når en kroppslängd (huvud och bål) av 23 till 35 cm och en svanslängd av 30 till 42 cm. De väger vanligen 350 till 570 g. Pälsen är på ryggen blek gulbrun till orange och vid buken ljusare till vitaktig. Arten har i motsats till flera andra lansråttor mjuk päls och saknar borstar eller taggar. Den tredje och fjärde tån vid fram- och backfötter är förlängd och lite bredare än de andra tårna. Kannabateomys amblyonyx skiljer sig från släktet Dactylomys i avvikande detaljer av skallens och tändernas konstruktion.[6] Huvudet kännetecknas av en nästan fyrkantig nos, gråa kinder, vita läppar och långa morrhår. Vanligen är hannar lite större än honor men inte hos alla populationer.[7]

Arten är aktiv på natten och klättrar i växtligheten. Den har höga läten, troligen för att markera reviret. Honor föder vanligen en och sällan två ungar per kull. Annars motsvarar arten andra lansråttor i levnadssättet.[6] Kannabateomys amblyonyx äter blad, bambu och unga växtskott. Oftast etablerar varje individ ett revir och ibland förekommer monogama par. Reviren från hannar och honor överlappar varandra. Antagligen jagas arten av mösskapucin (Cebus apella). Den jagar i alla fall andra gnagare i samma region.[7]

Huvudet kännetecknas av en nästan fyrkantig nos, gråa kinder, vita läppar och långa morrhår. Vanligen är hannar lite större än honor men inte hos alla populationer.

Arten är aktiv på natten och klättrar i växtligheten. Den har höga läten, troligen för att markera reviret. Honor föder vanligen en och sällan två ungar per kull. Annars motsvarar arten andra lansråttor i levnadssättet. Kannabateomys amblyonyx äter blad, bambu och unga växtskott. Oftast etablerar varje individ ett revir och ibland förekommer monogama par. Reviren från hannar och honor överlappar varandra. Antagligen jagas arten av mösskapucin (Cebus apella). Den jagar i alla fall andra gnagare i samma region.

대서양대나무쥐 ( Korece )

wikipedia 한국어 위키백과 tarafından sağlandı

대서양대나무쥐 또는 남부대나무쥐(Kannabateomys amblyonyx)는 가시쥐과에 속하는 남아메리카 설치류다. 아르헨티나브라질 그리고 파라과이의 습윤 열대 숲에서 발견된다. 대서양대나무쥐속(Kannabateomys)의 유일종이다.

특징

대서양대나무쥐의 머리부터 몸까지 몸길이는 최대 25cm이고 꼬리 길이는 32cm이다. 몸무게는 약 475g이다. 털은 일반적으로 대부분의 설치류처럼 아구티 갈색부터 회색을 띠며, 옆구리는 밤색으로 색조가 변한다. 볼과 하체는 불그스레한 갈색과 함께 흰 색조를 띤다. 꼬리가 시작되는 6cm 정도는 털이 잘 나 있지만 나머지 부분은 숱이 적게 나 있다. 꼬리 끝은 독특한 장식술 형태의 털이 나 있다. 다 자라면, 긴 꼬리를 갖게 되며 다른 종들과 혼동을 일이키지 않게 된다.[2]

분포 및 서식지

남아메리카의 토착종으로 브라질 남동부 지역과 파라과이 동부 그리고 아르헨티나 북동부 지역에 분포한다. 일반적인 서식지는 울창한 대나무 숲 하층과 함께 물 근처의 습윤 숲이다. 특히 덤불을 형성하는 대형 대나무의 일종인 구아두아 앙구스티폴리아(Guadua angustifolia) 숲에서 서식한다.[3]

생태

대서양대나무쥐는 야행성 동물이고, 고도의 수상성 생활을 하며, 특히 물 근처의 나무와 대나무 주변을 기어 오르다. 세력권 면적은 약 100m2이다. 경고를 할 때 큰 소리를 낸다.[2] 풀과 잎, 새싹, 과일과 덩이줄기 등을 먹는 것으로 추정된다.[4]

보전 상태

대서양대나무쥐는 흔한 종은 아니다. 예를 들어, 브라질 히우그란지두술주에서 평방 킬로미터 당 겨우 4마리의 밀도를 갖는 것으로 기록되고 있다. 야행성 동물이기 때문에 거의 관찰되지 않지만, 광범위한 분포 범위를 가지고 있으며 큰 전체 개체군을 가지는 것으로 추정된다. 브라질 미나스제라이스주와 같은 일부 지역에서는 숲 개간 때문에 국지적으로 위협을 받고 있지만 다른 특정한 위협은 확인되지 않으며, 국제 자연 보전 연맹(IUCN)이 보전 등급을 "관심대상종"으로 지정하고 있다.[1]
