Life Expectancy

provided by Animal Diversity Web

Information does not exist on the lifespan of C. fuliginosus, partly because of the inaccessible and rugged habitat in which they live. Given their small size, it is not likely that they live many years.

Behavior

provided by Animal Diversity Web

These animals have poor sight, but well-developed senses of smell and hearing, as well as sensitive and long vibrissae. They most likely use their well-developed senses to locate their prey in the evening and at night. However, because of their sensitive hearing, they most likely communicate with each other through sound, and identify each other through their unique sense of smell.

Conservation Status

provided by Animal Diversity Web

The conservation status of this species is unknown, mainly because of the inaccessible and rugged habitat it lives in, the fact that not many specimens have been captured, and that little is known about its life span and environmental interactions. It was once considered rare, but more recent studies have started suggesting otherwise.

US Federal List: no special status

CITES: no special status

IUCN Red List of Threatened Species: least concern

Benefits

provided by Animal Diversity Web

These animals have little effect on humans, and live in a completely different habitat. However, in human’s search for cures, some research has started to take place in this family, Caenolestidae. The breast cancer BRCA1 protein is being studied in many marsupials, including C. fuliginosus.

Trophic Strategy

provided by Animal Diversity Web

Silky shrew opossums are mainly insectivorous, and can use their incisors to probe in search of insects. However, they are also known to hunt and kill other small vertebrates and earthworms for food. Even small seeds have been found in the digestive tracts. They hunt in the early evening and at night; they are mostly nocturnal. They use their long vibrissae (whiskers) and well-developed sense of hearing to locate their prey.

Animal Foods: mammals; insects; terrestrial worms

Plant Foods: seeds, grains, and nuts

Primary Diet: carnivore (Insectivore )

Morphology

provided by Animal Diversity Web

Caenolestes fuliginosus is sexually dimorphic. The mass of females ranges from 16.5 to 22.4 g, and the mass of males ranges from 25 to 40.8 g. The head and body length is between 90 and 135 mm; including the tail, their length ranges from 93 to 139 mm. Pelage contains hairs with different textures, which creates an uneven appearance. The fur is soft and thick, with dark brown to almost black dorsally, and noticeably lighter fur on the ventrum. The non-prehensile tail is the same color as the dorsal pelage and is almost naked. The head is elongated (similar to that of a rat), with small eyes, and ears extending above the fur line. Upper and lower lip flaps are present. Feet each have five digits. On the forefeet, the two outer digits have blunt claws, and the inner three digits have sharp curved nails. Digits on the hind feet display curved claws except for the inner digit. The inner digit on both hind feet is small with a small nail.

Range mass: 16.5 to 40.8 g.

Range length: 93 to 139 mm.

Other Physical Features: endothermic ; homoiothermic; bilateral symmetry

Sexual Dimorphism: male larger

Associations

provided by Animal Diversity Web

Any larger animal living in the Andes that has access to C. fuliginosus terrain could be a possible predator. To protect themselves, silky shrew opossums are cryptically colored, and their keen sense of hearing and smell allow them a chance to quickly run for safety.

Anti-predator Adaptations: cryptic

Reproduction

provided by Animal Diversity Web

Not much is known about the mating system of silky shrew opossums other than the fact that these animals reproduce sexually. Females are predicted to be reproductively active only in the summer, because all female Rhyncholestes (another genus of shrew opossum in the family Caenolestidae) captured in the spring had unperforated vaginae and showed no signs of pregnancy or lactation. The extreme sexual dimorphism suggests that these animals may be polygynous.

Females are reproductively active only in the summer. August has been the only time of year when suckling young have been captured. However, male shrew opossums are capable of breeding all year long, based on the position of their testes. Because silky shrew opossums have two pairs of mammae, it is predicted that they could have between 1 and 6 offspring in a litter, based on the pattern of lactating female teat development. However, no actual observations of litters have been reported.

Breeding interval: Breeding is predicted to occur once yearly.

Breeding season: Breeding is likely to take place in early July, although males may be capable of breeding year round.

Average gestation period: 1 to 1.5 months.

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

Observations of maternal behavior have not been made directly. It is predicted that females utilize a form of nesting during the reproductive season based on the fact that few or no females have been trapped anytime soon after giving birth, and no attached offspring have been found. The marsupium in this species is confined to juveniles. Offspring in marsupials are always altricial, because the lack of placentation does not allow complete development of the young prior to birth.

In the genus Rhynolestes, also in the family Caenolestidae, there have been suspected "family groups" captured. In four consecutive nights one adult male, one adult female, and two juveniles were captured in the same trap in the same location that had not been washed between captures. If this in fact was a family group, it could suggest both male and female parental care.

Parental Investment: altricial ; pre-fertilization (Provisioning, Protecting: Female); pre-hatching/birth (Provisioning: Female, Protecting: Female); pre-weaning/fledging (Provisioning: Female, Protecting: Female); pre-independence (Provisioning: Female, Protecting: Female)

Vačík rejsčí ( Czech )

provided by wikipedia CZ

Vačík rejsčí (Caenolestes fuliginosus) žije v Jižní Americe, přesněji v Ekvádoru, Kolumbii a severozápadní Venezuele. Preferuje chladné a vlhké prostředí. Je to drobný vačnatec. Samice nemají vyvinutý vak (objevuje se pouze u mláďat, později zaniká). Mláďata jsou uchycena pevně na strucích bez ochrany vaku.

Potravou jsou malí bezobratlí živočichové a holátka, které loví v podvečer. K lovu používají dlouhé vibrissae (vousy) a dobře vyvinutý sluch. V zažívacím traktu byla objevena i semena, takže nepohrdne ani rostlinnou stravou. V zajetí se chová jen výjimečně.

Morfologie

Tělo je 14 cm velké a téměř holý ocas je do 14 cm dlouhý. Váží kolem 40 g. Ocas není chápavý, ale používá ho jako třetí nohu (když sedí vzpřímeně). Srst se skládá z různých textur, což způsobuje nerovnoměrný vzhled (měkká, hustá srst). Zbarvení bývá tmavší nahoře od tmavě hnědé až téměř černé. Malé uši vyčnívají ze srsti a oči jsou velmi malé. Zadní tlapky mají dobře vyvinuté, mají zakřivené drápy na všech prstech.

Ecuador-Opossummaus ( German )

provided by wikipedia DE

Die Ecuador-Opossummaus (Caenolestes fuliginosus) ist eine Art der Eigentlichen Opossummäuse innerhalb der Mausopossums (Caenolestidae). Sie lebt in den nördlichen Anden in Teilen Kolumbiens, Ecuadors und Venezuelas.

Merkmale

Die Ecuador-Opossummaus erreicht eine Gesamtlänge von 229 bis 237 Millimetern und eine Schwanzlänge von 107 bis 113 Millimetern. Die Hinterfußlänge ist mit 20 bis 21 Millimeter vergleichsweise kurz, das Gewicht beträgt 34 bis 39 Gramm. Wie die anderen Arten der Mausopossums ähnelt sie in ihrem Aussehen den Spitzmäusen und besitzt eine lang ausgezogene Schnauze. Der Körper ist im Vergleich zu den anderen Arten der Gattung zart gebaut und die Art ist etwas kleiner mit kleinerem Schädel. Das Fell ist glänzend und seidig, es ist dunkelgrau gefärbt und besitzt hellere Haarspitzen und auch die Bauchseite ist dunkelgrau. Der lange Schwanz ist dunkelbraun und kann teilweise als Greifschwanz eingesetzt werden und dabei das Tier beim Klettern unterstützen.[1] Wie andere Arten der Mausopossums haben auch Vertreter dieser Art für Beutelsäuger ungewöhnliche Lippenklappen, die wahrscheinlich dafür sorgen, dass die Tiere nicht ungewollt Erde in das Maul bekommen. Die Tiere haben kurze und kräftige Beine mit je fünf Zehen, wobei die mittleren drei Zehen jeweils kürzer als die äußeren Zehen sind. Die Oberarmknochen sind sehr kräftig, die Oberschenkelknochen dagegen vergleichsweise schmal.[1]

4 · 1 · 3 · 4 = 42 3 · 1 · 3 · 4
Zahnformel der Eigentlichen Opossummäuse

Wie andere Arten der Mausopossums besitzt auch diese Art ein für die Familie typisches Gebiss mit vergrößerten unteren mittleren Schneidezähnen, die nach vorn ragen, sowie der reduzierten Anzahl an Schneidezähnen im Vergleich zu anderen Beutelsäugern. Die Arten der Gattung besitzen vier Schneidezähne (Incisivi), einen Eckzahn (Caninus), drei Prämolaren (Praemolares) und zwei Mahlzähne (Molares) in einer Oberkieferhälfte, im Unterkiefer verfügen sie über einen Schneidezahn weniger pro Hälfte. Insgesamt besitzen die Tiere entsprechend 46 Zähne.[1]

Wie andere Beuteltiere haben auch die Mausopossums zwei Uteri und zwei Vaginae, zudem wird angenommen, dass die Anzahl der Eierstöcke der Anzahl der Zitzen entspricht (anders als bei den Opossums). Die Arten der Eigentlichen Opossummäuse besitzen keine Bauchtasche (Beutel); sie haben jedoch vier Zitzen, von denen sich je zwei an den Bauchseiten am Hinterleib befinden.[1]

Verbreitung

 src=
Verbreitungsgebiet (grün) der Ecuador-Opossummaus

Die Ecuador-Opossummaus kommt in den südamerikanischen Anden im Norden und Westen Kolumbiens, in Ecuador sowie im äußersten Westen Venezuelas vor. Die Höhenverbreitung der Art reicht im Kolumbien von 2000 bis 3000 Meter und in Ecuador von 1600 bis 4000 Meter.[2] Der Großteil der gefangenen Individuen stammt allerdings aus Höhen von unter 2400 Metern.[1]

Lebensweise

 src=
Páramo in Ecuador, der typische Lebensraum der Ecuador-Opossummaus

Über die Lebensweise der Ecuador-Opossummaus liegen nur wenige Angaben vor, obwohl sie die häufigste und am weitesten verbreitete Art ihrer Gattung ist. Sie lebt unter anderem in den typischen Páramo-Gebieten der Anden,[2] zudem in Nebel- und Hochlandwäldern, wobei sie einen dichten Unterwuchs benötigt. Der Lebensraum besteht vor allem aus dem Unterwuchs mit kühlem und feuchtem Mikroklima in Gebieten mit regelmäßigen Regenfällen.[1] In Ecuador fehlt die Art wahrscheinlich in den höheren Lagen der Anden, da sie hier in direkter Konkurrenz mit der Spitzmaus-Art Cryptotis montivaga steht.[3][2]

Die Tiere der Gattung sind Einzelgänger und vor allem im frühen Abend und in der Nacht aktiv, wobei sie sich auf regelmäßig genutzten Pfaden durch den dichten Unterwuchs bewegen. Sie leben am Boden, sind jedoch auch gute Kletterer. Den Tag verbringen sie in Tunnelbauen unter Baumwurzeln.[1] Sie ernähren sich opportunistisch und sind omnivor. Dabei leben sie vor allem von Insekten, fressen jedoch auch pflanzliche Nahrung, vor allem Früchte, und erbeuten auch kleine Wirbeltiere, darunter auch kleine und junge Mäuse. Unter den Insekten erbeuten sie vor allem Käfer, Fliegen, Grillen und Grashüpfer sowie Schmetterlinge und deren Raupen, hinzu kommen Regenwürmer, Hundertfüßer und Spinnen. Die Beute suchen sie in der Vegetation, vor allem in Moospolstern und Laubhaufen. Ihre Beute halten sie beim Fressen mit den Vorderfüßen fest.[1]

Über das Paarungsverhalten der Mausopossums liegen keine Beobachtungen vor, wahrscheinlich haben die Tiere eine Fortpflanzungsphase pro Jahr, die von Februar bis August andauert. Die Weibchen der Gattung und damit auch der Ecuador-Opossummaus besitzen allerdings keine Bauchtasche wie andere Beuteltiere. Bei Jungtieren ist eine Bauchfalte ausgebildet, die sich jedoch bis zum Erreichen der Geschlechtsreife zurückbildet. Bei einem gefangenen weiblichen Tier konnten drei Embryonen aufgefunden werden, von denen sich zwei im rechten Uterus und eines im linken entwickelten. Bei mehreren gefangenen Weibchen konnte eine Laktation (Milchgabe) im August festgestellt werden.[1]

Systematik

Die Ecuador-Opossummaus wird als eigenständige Art innerhalb der Gattung der Eigentlichen Opossummäuse (Caenolestes) eingeordnet. Die Gattung enthält insgesamt fünf Arten, wobei eine Art (Caenolestes sangay) erst 2013 erstbeschrieben wurde.[4] Die wissenschaftliche Erstbeschreibung der Ecuador-Opossummaus stammt von Robert Fisher Tomes aus dem Jahr 1863 anhand eines Individuums aus Ecuador.[5]

Innerhalb der Art werden drei Unterarten unterschieden:[5]

  • Caenolestes fuliginosus fuliginosus
  • Caenolestes fuliginosus centralis
  • Caenolestes fuliginosus obscurus

Bestand, Gefährdung und Schutz

Die Ecuador-Opossummaus wird von der International Union for Conservation of Nature and Natural Resources (IUCN) aufgrund des vergleichsweise großen Verbreitungsgebietes und der angenommenen großen Populationen als nicht gefährdet (least concern) eingestuft. Ursachen für eine potenzielle Bestandsbedrohung sind nicht bekannt, regional wird der Lebensraum der Art allerdings intensiv für Viehhaltung genutzt.[2]

Opossum bugeddum skur ( Maltese )

provided by wikipedia emerging languages

L-Opossum bugeddum skur (Caenolestes fuliginosus), li jsibuh ukoll bħala Opposum bugeddum tal-ħarir, huwa marsupjal żgħir li jgħix fil-foresti alpini tal-Andi. Mis-seba' speċijiet tal-ordni Paucituberculata, li għadhom ħajjin illum, dan huwa l-aktar opossum bugeddum li hu magħruf u l-aktar wieħed li hemm tagħrif u informazzjoni dwaru.

Deskrizzjoni

Din l-ispeċi hija simili ħafna tal-ispeċi l-oħrajn li qegħdin miġburin fl-istess ġeneru (Caenolestes).

L-opossum bugeddum skur għandu l-pil fin u folt ta' lewn kannella skur li jkanġi fl-iswed fuq id-dahr, filwaqt li jiċċara ħafna fin-naħa taż-żaqq. Il-wiċċ tawwali li ġej għall-ponta mgħammar b' par għajnejn ċkejknin.

Din l-ispeċi ta' opossum bugeddum tippreżenta fiha dimorfiżmu sesswali qawwi fejn in-nisa huma ta' daqs notevolment iżgħar. It-tul tar-ras u l-ġisem huwa bejn 90 u 140 millimetru u d-denb kważi għarwien kapaċi jilħaq jew iqarreb dan it-tul ukoll. Il-piż totali ta' l-irġiel ijvarja bejn 25 u 41 gramma filwaqt il-piż tan-nisa jvarja bejn 16.5 u 22.5 grammi u ma għandhomx marsupju.

Dieta

L-Opossum bugeddum skur huwa marsupjal b'dieta karnivora li tikkonsisti minn varjetà ta' insetti u annimali vertebrati u invertebrati żgħar.

Distribuzzjoni

Id-distribuzzjoni ta' dan il-marsupjal tal-Amerika t'Isfel hija l-akbar fost l-ispeċi ta' din l-ordni. L-opossum ġurdien skur qiegħed mifrux fil-boskijiet u fil-prateriji umdi, f'altitudni bejn 1,500 u 4,000 metru, fil-Peru, l-Ekwador, il-Kolombja u l-Veneżwela, fejn jiċċaqlaq minn post għall-ieħor billi jħaffer mini taħt l-art.

Klassifikazzjoni

Opossum bugeddum skur jew Opposum bugeddum tal-ħarir hemm erba' sottospeċijiet.

Konservazzjoni

Din l-ispeċi, fil-lista l-ħamra tal-Unjoni Internazjonali għall-Konservazzjoni tan-Natura (IUCN red list) qiegħda mniżżla bħala fi stat ta' riskju ta' estinzjoni baxx.

Dusky caenolestid

provided by wikipedia EN

The dusky caenolestid (Caenolestes fuliginosus), also known as Tate's shrew opossum,[2] is a shrew opossum from South America. The dusky caenolestid is characterized by a dark brown coat with a lighter underbelly, soft and thick fur, and a loosely haired tail. A nocturnal animal (active mainly at night), the dusky caenolestid lives on trees and feeds on insects and small invertebrates and vertebrates. It occurs in alpine and páramo forests in northern and western Colombia, Ecuador, and western Venezuela. The IUCN classifies this shrew opossum as least concern.

Taxonomy and etymology

The dusky caenolestid is one of the five members of Caenolestes, and is placed in the family Caenolestidae (shrew opossums). It was first described by English zoologist Robert Fisher Tomes as Hyracodon fuliginosus in 1863.[3] It was given its present binomial name by English zoologist Oldfield Thomas in 1895.[4] In the latter part of 20th century, scientists believed that Caenolestes is closely related to Lestoros (the Incan caenolestid).[5][6] Over the years, it became clear that Lestoros is morphologically different from Caenolestes.[4] A 2013 morphological and mitochondrial DNA-based phylogenetic study showed that the Incan caenolestid and the long-nosed caenolestid (Rhyncholestes raphanurus) form a clade sister to Caenolestes. The cladogram below is based on this study.[7]

Gray short-tailed opossum (Monodelphis domestica)

Brown four-eyed opossum (Metachirus nudicaudatus)

Incan caenolestid (Lestoros inca)

Long-nosed caenolestid (Rhyncholestes raphanurus)

Caenolestes

Northern caenolestid (C. convelatus)

Dusky caenolestid (C. fuliginosus)

Andean caenolestid (C. condorensis)

Gray-bellied caenolestid (C. caniventer)

Eastern caenolestid (C. sangay)

Three subspecies are recognized:[4]

Caenolestid fossils date to as early as the early Eocene (nearly 55 mya). The generic name Caenolestes derives from the Greek words kainos ("new") and lestes ("robber", "pirate").[8]

Description

The dusky caenolestid is characterized by a dark brown coat with a lighter underbelly, soft and thick fur, and a loosely haired tail. The head-and-body length is between 9.3 and 13.5 centimetres (3.7 and 5.3 in), the tail measures 9.3 to 12.7 centimetres (3.7 to 5.0 in) and hindfeet are 2.2 centimetres (0.87 in) long. The ears and eyes are smaller and the rostrum is longer than in other caenolestids.[9] The forefeet have five digits each; while two of them are blunt, the other three digits bear sharp claws. The toes of the hindfeet bear sharp claws as well, except for the biggest toe. There are four teats and no pouch.[10] A 2007 study recorded dental anomalies such as missing teeth and supernumerary teeth.[11]

Ecology and behavior

The dusky caenolestid is nocturnal (active mainly at night), and lives on trees. It can be a fast runner, like the Incan caenolestid, though it does not move in leaps and jumps. The dusky caenolestid is reported to have a poor vision, though its sense of smell and hearing are good.[10] Diet consists of lepidopteran larvae, insects, rodents, arachnids and centipedes; plant material may be eaten as well.[9] The tail, though prehensile, may not be able to support the animal when it hangs down a branch.[12]

Distribution and status

The dusky caenolestid inhabits alpine and páramo forests in northern and western Colombia, Ecuador, and western Venezuela. It can occur in an altitudinal range of 1,600–4,000 metres (5,200–13,100 ft) above the sea level. The IUCN classifies it as least concern given its wide distribution and presumably large numbers. The caenolestid faces competition from the wandering small-eared shrew, and is thus rare, in montane regions of Ecuador. Cattle grazing is a major factor in habitat degradation.[1]

Zbójnik ciemny[3], zbójnik[4][a] (Caenolestes fuliginosus) – gatunek ssaka z rodziny zbójnikowatych (Caenolestidae)[5].

Występowanie

W północno-zachodniej części Ameryki Południowej: Wenezueli, Kolumbii, Peru i Ekwadorze.

Wygląd i budowa

Ma krótką, brunatnoczarną sierść. Głowa wydłużona, jak u szczura, oczy bardzo małe, uszy zaokrąglone, wystające ponad futrem. Ogon niechwytny, skąpo owłosiony. Długość głowy i tułowia 10,5-13,5 cm, tyle samo mierzy ogon. Dymorfizm płciowy jest wyraźnie zaznaczony – samce są znacznie cięższe od samic. Charakterystyczny dla zbójników jest brak torby lęgowej.

Biologia i etologia tego gatunku są słabo poznane. Zbójniki mają słaby wzrok, ale dobrze rozwinięty słuch i węch. Odżywiają się bezkręgowcami (owady, pająki).

Podgatunki

Wydzielono następujące podgatunki[1][5]:

  • Caenolestes fuliginosus centralis Bublitz, 1987
  • Caenolestes fuliginosus fuliginosus (Tomes, 1863)

Caenolestes fuliginosus ( Swedish )

provided by wikipedia SV


Caenolestes fuliginosus[2][3][4] är en pungdjursart som först beskrevs av Robert Fisher Tomes 1863. Caenolestes fuliginosus ingår i släktet Caenolestes och familjen inkanäbbmöss.[5][6] IUCN kategoriserar arten globalt som livskraftig.[1] Ibland används Ecuadors inkanäbbmus som svenskt trivialnamn.

Utseende

Arten når en absolut längd av 23 till 24 cm, inklusive en cirka 11 cm lång svans. Den liknar liksom släktets andra medlemmar en näbbmus i utseende. Vikten varierar mellan 34 och 39 g. Den lena pälsen har en mörkbrun till mörkbrun färg och det finns inga påfallande skillnader mellan ovansida och undersida. Svansen kan i viss mån användas som gripverktyg men den kan inte bära hela kroppen.[7]

Hos Caenolestes fuliginosus är två framtänder som ligger i mitten av underkäken förlängd vad som skiljer arten från släktets andra medlemmar. Liksom andra inkanäbbmöss har arten flikar vid läpparna som troligen förhindrar att skräp når dess morrhår eller munhålan. Trots att arten tillhör pungdjuren saknar honor pung (marsupium).[7]

Utbredning och habitat

Pungdjuret förekommer i bergstrakter i Colombia och Ecuador. Regionen ligger 1 600 till 4 000 meter över havet. Habitatet utgörs av bergsskogar och landskapet páramo (bergstundra).[1]

Ekologi

Individerna lever allmänt ensam och de är aktiva på kvällen och på natten. De går främst på marken men kan klättra i växtligheten. Viloplatsen är en tunnel i marken eller en hålighet bland rötter. Födan utgörs främst av ryggradslösa djur som insekter, spindlar och daggmaskar. Dessutom äts några växtdelar som mossa eller blad.[7]

Honor har fyra spenar och kan ha upp till fyra ungar per kull.[7]

Underarter

Arten delas in i följande underarter:[5]

  • C. f. centralis
  • C. f. fuliginosus
  • C. f. obscurus
