Behavior

provided by Animal Diversity Web

Conover's tuco-tucos, like all other tuco-tucos, earned their common name in part for the alarm call emitted by males due to territoriality or fear. The calls last 10 to 20 seconds, beginning at a slow rate and increasing throughout. In reality, the sound is more of a "tloc tloc tloc" than a "tuco tuco."

Although details are not available, it is also likely that these animals communicate with one another through visual signaling. They also are likely to have tactile communication, especially between mates, parents and offspring, and rivals.

Communication Channels: visual ; tactile ; acoustic

Perception Channels: visual ; tactile ; acoustic ; chemical

Associations

provided by Animal Diversity Web

As rodents in the Chacoan ecosystem, C. conoveri serve as an important food item for many predators, including owls, diurnal raptors, carnivorous mammals such as the maned wolf and the pampas fox, and feral cats. The males are aposematic, meaning that they elicit alarm calls as an antipredatory adaptation; additionally, the placement of the eyes allows these animals to look out of their burrows without exposing the rest of the body.

Known Predators:

  • great horned owls (Bubo virginianus)
  • pampas foxes (Lycalopex gymnocercus)
  • diurnal raptors (Falco)
  • feral cats (Felis silvestris)

Anti-predator Adaptations: aposematic

Morphology

provided by Animal Diversity Web

Conover's tuco-tucos are large for this genus, and can reach weights in excess of 1 kg. This species strongly resembles North American pocket gophers (Geomyidae). As a fossorial species, they have a robust and cylindrical body, large head, short and sparsely haired tail, and short, muscular neck and forelimbs. The eyes are medium-sized and positioned to enable these animals to look out of the burrow without exposing the whole body. The external ears are very small, another adapation to fossorial living. The forelimbs are slightly shorter than the hindlimbs, and all digits have claws. The claws on the forefeet are the longest, and are used for loosening packed earth.

The skin seems loosely applied to the body, possibly making it easier for these animals to turn around in narrow burrows. The soles of the hind feet are equipped with comb-like bristles, composed of hair fringes, and are used to groom dirt from the fur.

Conover's tuco-tucos have a tan dorsum with a faint mid-dorsal line. The top of the head is a gray-brown, lightening to flecking on the back of the head. The cheeks are a brownish-yellow, and touches of white surround the mouth and chin. The ventrum is also a light yellow. Generally, the fur is thick and long.

Like other Ctenomys, Conover's tuco-tucos have a broad, flattened skull. They lack a sagittal crest but have prominent ridges along the parietals. The zygomatic arches are strongly bowed outward, and the jugal bone does not contact the lacrimal bone. They are equipped with large auditory bullae and large paroccipital processes. The dental formula is 1/1, 0/0, 1/1, 3/3 = 20. Ctenomys concoveri is noted for prominent broad and heavy proodont incisors; each of the anterior surfaces has an inner and outer wide lateral groove and three shallow, narrow median grooves. These incisors, covered by a bright orange enamel, are used to gnaw roots when digging. This species also has kidney-shaped hypsodont molars for chewing vegetation, with the last molar being reduced.

Although males are reported to be larger than females, the following measurements apply to both sexes. Total length of these animals ranges from 338 to 442 mm (average = 403.3 mm); head and body length varies from 245 to 328 mm (average = 293.3 mm); tail length ranges between 93 and 137 mm (average = 110.0 mm); hindfoot length is between 52 and 62 mm (average = 58.0 mm); and ear length (notch to tip) is between 10 and 16 mm (average = 13.4 mm). The average adult weighs about 900 grams.

Average mass: 0.900 kg.

Range length: 338 to 442 mm.

Average length: 403.3 mm.

Sexual Dimorphism: male larger

Other Physical Features: endothermic ; bilateral symmetry

Habitat

provided by Animal Diversity Web

Ctenomys concoveri is a primarily fossorial species. Conover's tuco-tucos are found in areas of sandy or loamy soils. In the Paraguayan Chaco, the landscape is primarily savannah grassland and shrub forest. The shrub forest is characterized by thorny bushes, shrubs, and cacti, with scattered trees up to 13 m high. The dominant species in the forest include Prosopis ruscifolia, a thorny legume, and Opuntia sp. Much of the grassland is under severe agricultural pressure.

Average elevation: 250 m.

Habitat Regions: tropical ; terrestrial

Terrestrial Biomes: savanna or grassland ; scrub forest

Distribution

provided by Animal Diversity Web

Conover's tuco-tucos are endemic to the Chaco in both Bolivia and Paraguay, occurring at an altitude of 250 m. They are found from 20 degrees S to 23 degrees S and 60 degrees to 63 degrees. This species has one of the smallest ranges of the thirty-eight currently recognized species in the genus Ctenomys. As a genus, tuco-tucos are considered to exhibit considerable ecologic plasticity. The fossil record dates back to the Pliocene in this range. Currently, it is thought that a vicariant event cannot explain present distributions.

Biogeographic Regions: neotropical (Native )

Trophic Strategy

provided by Animal Diversity Web

Ctenomys conoveri is entirely vegetarian, feeding on roots, stems, and grasses of the Chacoan region. Its preference for plant material makes it a pest because of damage to cultivated crops--much like the North American pocket gophers (Geomyidae). It builds separate food burrows for food storing.

Plant Foods: leaves; roots and tubers

Foraging Behavior: stores or caches food

Primary Diet: herbivore (Folivore )

Associations

provided by Animal Diversity Web

The strong foraging habits of Conover's tuco-tucos have been crucial to maintaining habitat openings and providing regrowth forage for wild and domestic ungulates; They also aerate the soil through their burrowing behaviors. They present vital habitat via burrows to many species of mammals, lizards, toads, invertebrates, and, at times, birds. They are also a prey species for a viariety of raptors and carnivorous mammals.

Ecosystem Impact: creates habitat; soil aeration

Benefits

provided by Animal Diversity Web

Although often unrecognized, Conover's tuco-tucos do provide positive services for humans. Through their burrowing habits, they maintain wildlife habitat, which assists resource managers and ecotourists. Their excrement also provides a fertilizer for the soil and crops. Similarly, their burrowing habits may aid agriculturists in aerating and maintaining the soil. Their foraging habits oftentimes stimulate faster plant growth rather than halting it. More research is being conducted on them as interest in the Chacoan ecosystem and Ctenomys species continues to grow. They are also becoming more commonly listed on many pet trade web pages.

Benefits

provided by Animal Diversity Web

Similar to the prairie dog controversy in the American west, Conover's tuco-tucos create burrows that damage agricultural and graze areas. Additionally, as herbivores, they have done a lot of agricultural damage through their preference for roots, stems, and grasses. Many people believe their burrows result in injury and death for livestock, while others feel their foraging habits outcompete domestic livestock.

Negative Impacts: crop pest

Conservation Status

provided by Animal Diversity Web

Conservation efforts for this taxa are frought with taxanomic dispute and disregard for them by ranchers. Differentiation of the genus Ctenomys was historically based on pelage and morphological differences; it is now shifting to DNA and molecular sequencing, due to their substantial chromosomal variation. This species is highly understudied and misunderstood by local inhabitants. They are often persecuted by people, and desire and funding to study this species is often low. Conover's tuco tucos are not listed by CITES or IUCN.

US Federal List: no special status

CITES: no special status

IUCN Red List of Threatened Species: least concern

Reproduction

provided by Animal Diversity Web

Sexual size dimorphism and enlarged testes are observed in this and other Ctenomys species, suggesting polygynyis the primary mating system.

Mating System: polygynous

Female C. conoveri are monoestrus, bearing one litter per year. They construct lined nest chambers, typically below the level of the main tunnel.

Gestation length is not available for this species, but other species in the genus Ctenomys range from about 102 to 120 days. Litters range in size from 1 to 7 young. Young of this genus may be born at varying levels of altriciality. Some young are precocious, coming out fully furred and looking like miniature adults. Others are only slightly furry at birth, and may have their eyes closed. The condition of C. concoveri at birth has not been reported.

Young of Ctenomys talarum are reportedly able to fend for themselves by about 10 days of age, even though they are not the most precocious members of their genus at birth. Nursing is said to continue for 5 weeks, and sexual maturity is reached sometime around 8 months of age, for both males and females. It is likely that C. concoveri is similar.

Breeding interval: Conover's tuco-tuco breeds once a year.

Breeding season: The exact breeding season for these animals has not been reported.

Average gestation period: 203 days.

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

Ctenomys conoveri has altricial young. The females are generally responsible for care and feeding of the young. Male parental care has not been reported.

Parental Investment: no parental involvement; altricial ; pre-fertilization (Protecting: Female); pre-hatching/birth (Provisioning: Female, Protecting: Female); pre-weaning/fledging (Provisioning: Female, Protecting: Female); pre-independence (Protecting: Female)

Conover-Kammratte ( German )

provided by wikipedia DE

Die Conover-Kammratte (Ctenomys conoveri) ist eine Art der Kammratten. Die Art wurde 1946 von Wilfred Hudson Osgood aus Paraguay wissenschaftlich erstbeschrieben. Die Art kommt im Süden Boliviens sowie im Norden von Paraguay vor, über die Lebensweise der Tiere liegen nur wenige Informationen vor.

Merkmale

Die Conover-Kammratte ist die größte Art der Gattung. Sie erreicht eine Kopf-Rumpf-Länge von bis zu etwa 59 Zentimetern und eine Schwanzlänge von bis zu 12 Zentimetern bei einem Gewicht von bis zu 1,2 Kilogramm. Die Hinterfußlänge beträgt mit Klaue etwa 60 Millimeter, die Ohrlänge beträgt bis zu 15 Millimeter. Die Männchen sind dabei größer als die Weibchen. Das Fell der Tiere ist lang und relativ rau. Es ist gleichmäßig zimtbraun bis rotbraun mit leichten Einfärbungen von gräulichen und weißen Haaren auf der Rückenseite. Die Bauchseite ist blass sandbraun. Der Schwanz ist stark behaart, er ist auf der Oberseite rotbraun mit einer weißen Mittellinie bis zur Schwanzspitze sowie auf der Unterseite blassbraun.[1]

Der Schädel ist kräftig und kantig gebaut. Der Jochbogen hat einen ausgeprägten Kamm auf den hohen und breiten Dorsalfortsatz. Bei vielen ausgewachsenen Tieren ist das Fronto-Parietal-Fenster nicht geschlossen.[1]

Der Karyotyp besteht aus einem Chromosomensatz von 2n=48 Chromosomen (FN=64) in Bolivien und 2n=50 Chromosomen (FN=64) in Paraguay. Die Spermien sind leicht asymmetrisch gebaut.[1]

Verbreitung

Die Conover-Kammratte lebt im südlichen Bolivien in den Departamentos Santa Cruz, Chuquisaca und Tarija sowie im nördlichen Paraguay im Departamento Boquerón.[1]

Lebensweise

Die Lebensräume der Conover-Kammratte sind geprägt vom nördlichen Gran Chaco in einem trockenen und xerophytischen Strauchgebiet in Höhenlagen von etwa 2000 Metern. Sie lebt wie alle anderen Kammratten am Boden und im Boden grabend.[1] Es handelt sich um eine pflanzenfressende Art, die unterirdische Knollen und Wurzeln nutzt. Kolonien gibt es in Gebieten mit lockeren, nicht oft überfluteten Böden. Sie ist sowohl in ungestörten Lebensräumen als auch in durch Viehzucht gestörten Gebieten zu finden.[2]

Systematik

Die Conover-Kammratte wird als eigenständige Art in die Gattung der Kammratten (Ctenomys) eingeordnet. Diese besteht aus etwa 70 Arten.[1] Die wissenschaftliche Erstbeschreibung der Art stammt von dem amerikanischen Zoologen Wilfred Hudson Osgood aus dem Jahr 1946, der sie anhand eines Individuums aus dem paraguanischen Chaco nahe der Stadt Filadelfia beschrieb.[1] Osgood benannte die Art nach dem amerikanischen Hobby-Ornithologen Henry Boardman Conover, der unter anderem in Paraguay aktiv war.[3]

Die Art wurde innerhalb der Gattung teilweise in eine eigene Untergattung Chacomys eingeordnet. Aufgrund molekularbiologischer Merkmale wird sie allerdings aktuell als Schwesterart der Rötlichen Kammratte (Ctenomys frater) und der Lewis-Kammratte (Ctenomys lewisi) betrachtet und der frater-Gruppe innerhalb der Gattung zugeordnet.[4][1] Innerhalb der Art werden neben der Nominatform keine weiteren Unterarten unterschieden.[1]

Status, Bedrohung und Schutz

Die Conover-Kammratte wird von der International Union for Conservation of Nature and Natural Resources (IUCN) als nicht gefährdet gelistet.[2] Sie kommt in ihrem begrenzten Verbreitungsgebiet vergleichsweise regelmäßig vor. Die Population ist wahrscheinlich leicht fallend und vergleichsweise anpassungsfähig an Veränderung des Lebensraums. Es gibt derzeit keine bekannten bestandsgefährdende Bedrohungen für diese Art.[2] Sie kommt auch im Nationalpark Parque Nacional Kaa-Iya del Gran Chaco in Bolivien vor.[2]

Tukotuko duży ( Polish )

provided by wikipedia POL

Tukotuko duży[3] (Ctenomys conoveri) – endemiczny gatunek gryzonia z rodziny tukotuków (Ctenomyidae). Występuje w Chaco zarówno w Boliwii i Paragwaju poniżej wysokości 200 m n.p.m.[4][5][2]

Charakterystyka

Jak na przedstawicieli gatunków gryzoni ryjących przystało, mają solidne i cylindryczne ciała, dużą głowę, krótki ogon i krótką sierść. Oczy średniej wielkości. Zewnętrzne uszy są bardzo małe, przystosowane do życia w norach. Kończyny przednie są nieco krótsze niż tylne. Pazury przednich łap są dłuższe. Służą do wygrzebywania ziemi.

Długość tych zwierząt waha się od 338 do 442 mm (średnia = 403,3 mm); długość ogona wynosi między 93 i 137 mm (średnia = 110,0 mm). Przeciętny dorosły osobnik waży około 900 gramów, ale może osiągnąć masę znacznie ponad 1 kg. Na wolności żyją przeciętnie około 3 lat.

Kariotyp

Garnitur chromosomowy tego zwierzęcia tworzy 25 par (2n=50) chromosomów (FN=56)[6].

Środowisko naturalne

W paragwajskim Chaco tukotuko duży zamieszkują[7] przede wszystkim łąki i sawanny, lasy i zarośla złożone z kolczastych krzewów i kaktusów. Lubią obszary o glebach piaszczystych lub ilastych. C. conoveri ma skupiska rozsiane na obszarze wyznaczonym współrzędnymi: 20°S-23°S i 60°W-63°W. Ten gatunek tukotuko jest jednym z najmniejszych liczebnie spośród trzydziestu ośmiu obecnie rozpoznawanych gatunków rodzaju Ctenomys. Znaleziska kopalne wskazują na występowanie C. conoveri w pliocenie.

Tukotuko duże budują systemy tuneli o długości średnio 14 m, szerokości 5 do 7 cm, a zagłębione około 30 cm pod powierzchnią ziemi. W tunelach budują komory do przechowywania pożywienia.

Żywienie

Tukotuko duży podobnie jak pozostałe gatunki z rodzaju Ctenomysroślinożercami.

Komunikacja

Jak wszystkich innych tnazwa zwyczajowa pochodzi od części sygnałów alarmowych emitowanych przez samców z powodu chęci obrony terytorium i strachu. Rytmiczny dźwięk zbliżony raczej do "tlok tlok tlok" (a nie 'tuk, tuk') rozbrzmiewa przez 10 do 20 sekund.

Rozród

Samice tukotuko dużego mają jeden miot rocznie. Budują podłużną komorę gniazda, zwykle poniżej poziomu głównego tunelu. Ciąża trwa od około 102 do 120 dni. Mioty liczą od 1 do 7 młodych. Młode mogą być po urodzeniu w różnym stopniu rozwinięte i samodzielne. Jedne rodzą się z futrem i wyglądają jak miniatura dorosłych. Inne są nieowłosione i mogą mieć oczy zamknięte. Młode tukotuko bywają samodzielne już po 10 dniach, ale pod opieką matki pozostają około 5 tygodni. Dojrzałość płciową uzyskują po ok. 8 miesiącach. Tak prawdopodobnie jest też w przypadku C. conoveri.

Опис Осґуда, 1946

Голова сіро-коричнева, висвітлена крапчасто на потилиці, щоки коричнево-жовті, з білим відтінком навколо рота і на підборідді.

Поведінка

Риючий, рослиноїдний вид, що живиться підземними бульбами і коренями. Живе у районах з пухким ґрунтом, що не часто затоплюється. Мешкає в посушливих ксерофітних чагарниках Чако як у непорушених місцях проживаннях так і в областях, потурбованих скотарством.
