Associations

provided by Animal Diversity Web

Acacia rats inhabit the thickest and thorniest parts of Acacia trees, which is an extremely effective in predator avoidance. Their sandy pelage provides great camouflage and likely helps reduce predation risk. It is thought that owls are their primary predators, however, arboreal snakes (e.g., Dendroaspis spp.) are important predators as well.

Known Predators:

  • owls, (Strigiformes)
  • tree snakes, (Dendroaspis spp.)

Anti-predator Adaptations: cryptic

Morphology

provided by Animal Diversity Web

Acacia rats have a white venter and a grey-yellow dorsum. The fur is dense and soft and their ears are sparsely covered in hair. They have elongate hind- and forepaws, which possess long, curved claws. THeir brown tail is used to distinguish them from black-tailed tree rats. In addition, black-tailed tree rats have a more complete eye mask than acacia rats. Although they were once considered the same species, recent chromosomal evidence suggest they are distinct species. Acacia rats weigh between 63 and 100 g, with an average of 68 g. Weight can vary substantially in females, with weight increasing during lactation. Body length ranges from 12 to 16.3 cm, and the tail is often greater than or equal to the body, ranging from 13 to 21 cm. Sexual dimorphism has not been reported for this species.

Range mass: 63 to 100 g.

Average mass: 68 g.

Range length: 12 to 16.3 cm.

Other Physical Features: endothermic ; homoiothermic; bilateral symmetry

Sexual Dimorphism: sexes alike

Trophic Strategy

provided by Animal Diversity Web

Acacia rats are primarily granivorous, feeding on the seeds and foliage of acacia trees. They have been observed foraging on Acacia tortilis and Acacia erioloba. The leaves of shepherd’s trees and seeds of buffalo thorn are also considered an important part of their diet. Other primarily granivorous, they also consume the berries, grasses, roots, buds, and gum of acacias. Food is generally brought back to the nest preior to consumption. Inedible plant materials are often used in nest making. They may also consume carrion or invertebrates when available.

Animal Foods: carrion ; insects; terrestrial non-insect arthropods

Plant Foods: leaves; roots and tubers; wood, bark, or stems; seeds, grains, and nuts; sap or other plant fluids

Foraging Behavior: stores or caches food

Primary Diet: herbivore (Granivore ); omnivore

Reproduction

provided by Animal Diversity Web

There is little information on the mating system of Acacia rats. They give birth during the summer rainy season, when acacia foliage is present. Similar to many other murids, acacia rats are polygynandrous. Males expand their home ranges during breeding season, presumably in order to increase the likelihood of finding potential mates.

Mating System: polygynandrous (promiscuous)

There is little information available regarding the reproductive behavior of acacia rats, and that which is know was discovered via lab studies. They normally breeds every 3.5 months during summer (April through July) and litters consists of 2 to 5 pups, which weigh between 2.5 to 2.8 g t birth. Young are weaned 28 and 31 days old and reach sexual maturity at an average of 107 days. Pups begin walking after 15 days and incisors appear only after one day. Reproduction in acacia rats is thought to be similar to that of black-tailed tree rats.

Breeding interval: Acacia rats breed once every 3.5 months.

Breeding season: Acacia rats breed during the rainy season, which lasts from April through July.

Range number of offspring: 2 to 5.

Average number of offspring: 2.7.

Range weaning age: 28 to 31 days.

Average age at sexual or reproductive maturity (female): 107 days.

Average age at sexual or reproductive maturity (male): 107 days.

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

There is no information available regarding parental care in wild acacia rats. In captivity, young attach to the nipple and nurse while the mother moves around the local environment. Pups stay with their parents until they reach reproductive maturity.

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

Akazienratte ( German )

provided by wikipedia DE

Die Akazienratte (Thallomys paedulcus) oder Afrikanische Akazienratte[1] ist eine vor allem im südöstlichen Afrika vorkommende Nagetierart. Ihren Namen hat sie vom Akazienbaum, auf dem sie hauptsächlich lebt.

Beschreibung

Die Akazienratte erreicht eine Gesamtlänge von 31 cm und ein Gewicht von durchschnittlich 81 Gramm. Länge und Gewicht sind je nach Verbreitungsgebiet sehr variabel, Weibchen sind etwas kleiner und leichter. Der Schwanz ist gleich lang oder etwas länger als die Kopf-Rumpf-Länge. Die Oberseite ist hellgrau bis gelblichgrau gefärbt. Die Haare des weichen Fells haben gelblichbraune Spitzen. Die Akazienratte erscheint damit deutlich brauner als die ähnliche Art T. nigricauda.[2] Kinn, Kehle und der gesamte Bauch sind reinweiß, die Farbe geht über die Flanken allmählich zur Farbe der Oberseite über. Die Rückseiten der Hände und Füße sind dicht kurzbehaart und ebenfalls weiß. Der Schwanz ist braun und relativ dicht dunkel bis schwarz behaart.[3][4]

Die Akazienratte fällt durch eine schwarze „Maske“ auf, die sich von der Schnauze bis um die Augen erstreckt. Sie ist allerdings weniger ausgeprägt als bei T. nigricauda.[2] Die großen und breiten Ohren sind braun und stehen vom Kopf ab.[3][4]

Verbreitung und Lebensraum

Das Hauptverbreitungsgebiet der Akazienratte liegt im südöstlichen Afrika. Im Subsahara-Afrika erstreckt sich ihr Vorkommen vom südlichen Äthiopien und vom südlichen Somalia im Norden über Ostafrika, den südlichen Teilen der Demokratischen Republik Kongo, Angola und über den größten Teil Sambias. Von Sambia aus kommt sie nach Süden bis zum nordöstlichen Südafrika und nach Eswatini vor. Akazienratten sind in Wäldern, baumbestandenen Savannen und Akazienbuschland zu finden.[5]

Lebensweise

Akazienratten sind scheue, nachtaktive, arboreale (baumbewohnende) Tiere. Sie leben in kleinen Gemeinschaften, zumeist paarweise mit dem letzten Nachwuchs und weiteren Jungtieren. Bis zu acht Tiere bewohnen ein in Astgabeln gebautes Nest in den Kronen von Akazienbäumen oder Baumhöhlen.[3][4]

Nahrung

Akazienratten sind überwiegend Pflanzenfresser. Einen großen Teil ihrer Nahrung machen frische Blätter, die Spitzen von Zweigen, die Samen und Früchte verschiedener Akazienarten aus. Darüber hinaus fressen sie junge Blätter von Hirtenbäumen (Boscia albitrunca) und von Ziziphus mucronata.[4] Gelegentlich nehmen sie auch Insekten oder fleischliche Nahrung auf. Manche Populationen, die weit von Wasserstellen entfernt leben, kommen ohne das Trinken von Wasser aus.[3]

Fortpflanzung

Akazienratten bringen im Sommer zwei bis fünf Jungtiere je Wurf zur Welt.[4]

Taxonomie

Meester et al. (1964) akzeptierten Thallomys paedulcus als einzige Art der Gattung Thallomys mit vier Unterarten (T. p. paedulcus, T. p. nigricauda, T. p. shortridgei und T. p. damarensis).[3] Gordon (1987) belegte chromosomal die Anerkennung der beiden, seiner Meinung nach parapatrisch verbreiteten Arten Thallomys paedulcus und Thallomys nigricauda. Taylor et al. (1995) unterstützten die Existenz zweier Arten, sahen die Verbreitung aber nicht deutlich abgegrenzt, sondern breit sympatrisch überlappend. Die beiden Arten sind diploid, die Chromosomenzahl ist 2n=43-46 für Thallomys paedulcus und 2n=47-50 für Thallomys nigricauda.[2] Möglicherweise präsentiert Thallomys paedulcus einen Artkomplex mehrerer ähnlicher Arten, zur Klärung ihres taxonomischen Status sind weitere Untersuchungen notwendig.[5]

Thallomys paedulcus ( Dutch; Flemish )

provided by wikipedia NL

Thallomys paedulcus is een knaagdier uit het geslacht Thallomys dat voorkomt van Zuid-Ethiopië en Zuid-Somalië tot het noordoosten van Zuid-Afrika. Deze soort lijkt sterk op T. nigricauda, maar verschilt daarvan in een aantal kenmerken: het karyotype bedraagt 2n=43-47 (tegen 2n=47-50), de staart is bruin (in plaats van zwart) en de donkere vlekken op het gezicht die bij T. nigricauda duidelijk zichtbaar zijn, zijn vaag.

Thallomys paedulcus ( Swedish )

provided by wikipedia SV


Thallomys paedulcus[2][3] är en däggdjursart som först beskrevs av Carl Jakob Sundevall 1846. Thallomys paedulcus ingår i släktet Thallomys och familjen råttdjur.[4][5] IUCN kategoriserar arten globalt som livskraftig.[1] Inga underarter finns listade.[4]

Utseende

Arten når en kroppslängd (huvud och bål) av 12 till 16,3 cm och därtill kommer en lika lång eller något längre svans. Vikten är 63 till 100 g. Den mjuka och täta pälsen har på ovansidan en vitaktig färg medan undersidan är gulgrå. I motsats till arten Thallomys nigricauda, som har en svart svans, har Thallomys paedulcus en brunaktig svans. Dessutom är de mörka ögonringarna hos Thallomys paedulcus inte lika tydliga. De långa fram- och bakfötterna är utrustade med böjda klor.[6]

Utbredning och habitat

Denna gnagare förekommer från södra Etiopien och centrala Somalia till Angola och nordöstra Sydafrika. Habitatet utgörs av buskskogar, ofta med akacior som dominerande växt. Individerna lever i familjegrupper som bygger ett näste av växtdelar.[1]

Ekologi

Individerna är aktiva på natten och klättrar främst i växtligheten. De bygger bon av kvistar, gräs och blad som ofta platseras vid trädens rötter. Hanens revir överlappar med reviren av olika honor och vid kanterna även med revir av andra hanar. Thallomys paedulcus föredrar olika delar av akacior som föda som blad, frön, bär, unga skott och naturgummi. Födan kompletteras med gräs och andra växter samt i mindre mått med ryggradslösa djur och kadaver. Ofta transporteras födan till boet.[6]

Akaciorna i utbredningsområdet har taggar som ger skydd mot potentiella fiender. Ibland faller arten offer för ugglor eller för trädlevande ormar.[6]

Fortplantningen sker under sommarens regntid mellan april och juli. Honor kan ha två kullar under tiden med 3,5 månader mellanrum. En kull har två till fem ungar som väger i början 2,5 till 2,8 g. Ungarna diar sin mor 28 till 31 dagar. De blir könsmogna efter cirka 107 dagar. I fångenskap lever arten ungefär tre år.[6]
