The dull coat color of Rio Negro tuco-tucos is an example of cryptic coloration, as it would make them difficult to spot on a riverbank. Some predators include owls, foxes, armadillos, grison, and some snakes.

Known Predators:

  • owls (Strigiformes)
  • foxes (Lycalopex)
  • armadillos (Dasypodidae)
  • grison (Galictis vittata)
  • snakes (Serpentes)

Anti-predator Adaptations: cryptic

Morphology

provided by Animal Diversity Web

Rio Negro tuco-tucos are rodents with short necks, large heads with reduced ears, and short forelimbs with large claws. They are well suited for a fossorial lifestyle. Adults generally weigh between 100 and 700 grams and grow to 15 to 25 centimeters from snout to tail. The tail is hairless and stiff. Three distinct fur colors are found among these tuco-tucos: melanic (black), agouti (light and dark banded hairs with black tips), and dark-backed. How this variation arose genetically is being investigated. The robust incisors are orange on the anterior surface and are ever-growing. Rio Negro tuco-tucos can be distinguished from other tuco-tucos by the male phallus which has a “trilobed bacular tip and a pair of spikes within the intromittent sac.” Resting metabolic rates have not been calculated, but the basal metabolic rate of a similar species (Ctenomys australis) is around 0.343±0.053 liters of oxygen per hour.

Range mass: 100 to 700 g.

Range length: 15 to 25 cm.

Other Physical Features: endothermic ; homoiothermic; bilateral symmetry

Associations

provided by Animal Diversity Web

Little is known about the subtleties of the ecological role of Rio Negro tuco-tucos. Birds of prey, large snakes, and several carnivorous mammals prey on this rodent, and presumably some parasites would use them as hosts, although this is not well-studied. Rio Negro tuco-tucos are shy and solitary and are not commensals with humans.

Benefits

provided by Animal Diversity Web

Rio Negro tuco-tucos are not known to benefit humans, but because three fur phenotypes exist within relatively small isolated populations and because of profound differentiation within the species, they are currently being intensely studied by evolutionary biologists.

Positive Impacts: research and education

Behavior

provided by Animal Diversity Web

Rio Negro tuco-tucos signal to each other over long distances by "singing." The name "tuco-tuco" comes from the sound these animals make. A recording of their vocalizations can be found here: http://eto.fcien.edu.uy/gaboeng.htm. These animals communicate to demarcate territory and to find each other during the mating season.

Communication Channels: tactile ; acoustic ; chemical

Perception Channels: visual ; tactile ; acoustic ; vibrations ; chemical

Reproduction

provided by Animal Diversity Web

Little is known about the mating system of Rio Negro tuco-tucos. Presumably, it is similar to Pearson's tuco-tucos, Ctenomys pearsoni, which have been better studied. Courtship rituals involve aggressive displays between males and chemical and auditory stimulation. Rio Negro tuco-tucos sing during courtship. Males spend time with females before copulating, as females are induced ovulators.

Mating System: polygynous

The breeding season of Rio Negro tuco-tucos occurs during the late austral autumn. In a study by Tassino and Passos (2009), pregnant females were observed during the beginning of austral winter and lactating females were observed during the austral spring. Females generally bear 2 to 4 offspring after gestating for 100 days and lactate for about two months. Average time to weaning and average birth mass is unknown. In Ctenomys talarum average time to weaning is around 30 days from birth and the birth mass is 46.0 ± 16.43g.

Breeding interval: Rio Negro tuco-tucos breed once yearly.

Breeding season: Rio Negro tuco-tucos breed during the austral autumn (March to June).

Range number of offspring: 2 to 4.

Average gestation period: 100 days.

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

After copulation, males and females separate, with females taking care of the young until they become independent.

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

Ctenomys rionegrensis ( Swedish )

provided by wikipedia SV

Ctenomys rionegrensis är en gnagare i släktet kamråttor som förekommer i Sydamerika.[2]

Arten blir utan svans 15 till 25 cm lång och den väger 100 till 700 g. Den korta halsen, de små öronen, det stora huvudet och de stora klorna vid framtassarna är anpassningar till ett underjordiskt liv. Pälsen kan antingen vara helt svart, mörk på ovansidan och ljusare på undersidan eller agouti. Ctenomys rionegrensis har stora framtänder med orange tandemalj för att gräva. Arten skiljer sig från andra släktmedlemmar i avvikande detaljer av hannens penisben.[3]

Denna kamråtta har flera från varandra skilda populationer i nordöstra Argentina och västra Uruguay. Den lever i sanddyner vid floderna Rio Paraná, Río Negro och Río Uruguay.[1][3]

Ctenomys rionegrensis skapar underjordiska tunnelsystem och varje exemplar lever ensam. Hannar och honor träffas bara när honan är brunstig. Arten äter olika växtdelar som gräs, rötter och unga växtskott. För en bättre ämnesomsättning äter kamråttan liksom hardjur sin egen avföring (koprofagi). Parningen sker under hösten (mars till juni på södra jordklotet) och efter cirka 100 dagar dräktighet föds två till fyra ungar per kull. Livslängden i naturen uppskattas vara tre år. Arten har flera naturliga fiender som medelstora rovdjur, större bältdjur, ugglor och större ormar.[3]

I flera fall blev sanddynerna omvandlade till odlingsmark vad som minskar beståndets storlek. IUCN listar arten därför som starkt hotad (EN).[1]

Ctenomys rionegrensis: Brief Summary ( Swedish )

provided by wikipedia SV

Ctenomys rionegrensis är en gnagare i släktet kamråttor som förekommer i Sydamerika.

Arten blir utan svans 15 till 25 cm lång och den väger 100 till 700 g. Den korta halsen, de små öronen, det stora huvudet och de stora klorna vid framtassarna är anpassningar till ett underjordiskt liv. Pälsen kan antingen vara helt svart, mörk på ovansidan och ljusare på undersidan eller agouti. Ctenomys rionegrensis har stora framtänder med orange tandemalj för att gräva. Arten skiljer sig från andra släktmedlemmar i avvikande detaljer av hannens penisben.

Denna kamråtta har flera från varandra skilda populationer i nordöstra Argentina och västra Uruguay. Den lever i sanddyner vid floderna Rio Paraná, Río Negro och Río Uruguay.

Ctenomys rionegrensis skapar underjordiska tunnelsystem och varje exemplar lever ensam. Hannar och honor träffas bara när honan är brunstig. Arten äter olika växtdelar som gräs, rötter och unga växtskott. För en bättre ämnesomsättning äter kamråttan liksom hardjur sin egen avföring (koprofagi). Parningen sker under hösten (mars till juni på södra jordklotet) och efter cirka 100 dagar dräktighet föds två till fyra ungar per kull. Livslängden i naturen uppskattas vara tre år. Arten har flera naturliga fiender som medelstora rovdjur, större bältdjur, ugglor och större ormar.

I flera fall blev sanddynerna omvandlade till odlingsmark vad som minskar beståndets storlek. IUCN listar arten därför som starkt hotad (EN).

Ctenomys rionegrensis ( Ukrainian )

provided by wikipedia UK

Туко-туко Ріо-Негро (Ctenomys rionegrensis) — вид гризунів родини Тукотукових, що зустрічається в Аргентині в провінції Ентре-Ріос та в Уругваї в департаменті Ріо-Неґро. Поширення обмежується піщаними дюнами, які складають менше 10% площі ареалу.

Загрози та охорона

Піщані дюни, в яких живе цей вид, були пріоритетними для розширення плантацій сосни та евкаліпта. Велика частка популяції була викорінена з цієї причини. Заходи задля збереження виду не вживаються.
