Information is not currently available on the predators of gold-and-white marmosets, although they are probably eaten by a variety of rainforest carnivores. The related species, Callithrix flaviceps, makes more warning calls at higher levels of the canopy, which is believed to be in response to avian predators. Gold-and-white marmosets are vulnerable to avian predators and avoid predation by staying just below the rainforest canopy. In addition, these animals are very good at maneuvering among the trees, which can serve to their great advantage in escaping less agile predators.
There is no information on communication in gold-and-white marmosets, but a related species, Saguinas oedipus, uses acoustic communication mostly as well as visual displays and scent markings. This species uses calls to inform each member of its group about predators, food sources, and intruding groups of tamarins. Visual displays are used to express dominance and in intergroup challenges that occur where territories overlap. An individual may puff its hair, display its rump as well as white genitalia, and raise its tail. Chest-rubbing and sprawling are used for territorial purposes as well as to express the dominance of certain individuals in a group. Individuals sometimes enforce their scent on other group members by urinating in a tree hole that has been made to extract gum. This ensures that other group members will encounter their scent.
Communication Channels: visual ; tactile ; acoustic ; chemical
Other Communication Modes: scent marks
Perception Channels: visual ; tactile ; acoustic ; chemical
The largest threat to gold-and-white marmosets is habitat destruction. With the alarming rate at which rainforests are being cut down each year, these animals are quickly losing their habitat. Conservation and education efforts to inform the public about rainforest flora and fauna have been the most effective means for helping gold-and-white marmosets survive.

Callithrix chrysoleuca causes no known economic problems for humans.
Gold-and-white marmosets have no known positive economic importance to humans, aside from their roles in the healthy, native ecosystems they inhabit. They may attract ecotourism interest.
Positive Impacts: ecotourism
Gold-and-white marmosets help to disperse seeds and serve as prey for a small number of rainforest carnivores.
Ecosystem Impact: disperses seeds
Gold-and-white marmosets feed mainly on exudates from plants, primarily gums, but some saps as well. They have specializations that allow for this type of diet, including elongated, chisel-like lower incisors as well as a wide jaw. Both of these specializations allow gold-and-white marmosets to penetrate the bark of gum producing trees, which causes the tree to excrete the gum or sap they are searching for. Although tree gum is a staple in their diet, they also eat other foods such as seeds, fruits, nuts, and some insects and small vertebrates.
Animal Foods: birds; mammals; reptiles; insects; terrestrial non-insect arthropods
Plant Foods: seeds, grains, and nuts; fruit
Primary Diet: herbivore (Eats sap or other plant foods)
Gold-and-white marmosets (Callithrix chrysoleuca) are found in a small area in the Brazilian Amazon. Their range extends between the Rio Amazonas and the south bank tributaries of the Urariá-Canumã.
Biogeographic Regions: neotropical (Native )
Gold-and-white marmosets live in the tropical rainforests of the Amazon. They are found in the upper levels of the rainforest canopy.
Habitat Regions: tropical ; terrestrial
Terrestrial Biomes: rainforest
The longevitity of gold-and-white marmosets is unknown in the wild as well as in captivity. In captivity, other species of marmoset are known to live anywhere from 7 to 16 years.
Males and females of Callithrix chrysoleuca are monomorphic. Like many other marmosets and tamarins, gold-and-white marmosets have tufts of fur that set them apart from other primates. The tufts are comprised of long white hair and are located on the ears. Their coat is pale yellow to orange in coloration. The face is pink. In this species, as in other marmosets and tamarins, claws replace nails on most digits, supporting their scansorial mode of locomotion. Gold-and-white marmosets do not have opposable thumbs; this is also true of other marmosets and tamarins, but is unlike most other primates. The body length ranges from 19 to 26 cm, while the tail can reach 30 to 36 cm. Weight is not known for Callithrix chrysoleuca but other members of the subfamily Callitrichinae range from 300 and 450 grams.
Range length: 19 to 26 cm.
Other Physical Features: endothermic ; homoiothermic; bilateral symmetry
Sexual Dimorphism: sexes alike
Although not much research has been done on the mating system of gold-and-white marmosets, it is likely to be similar to that of other members of the subfamily to which it belongs, Callitrichinae. Callitrichine mating systems have been described as monogamous, polyandrous, polygynous, and polygynandrous. Mating systems vary among populations and genera. All four mating systems can be found in one social group of Callithrix chrysoleuca. It has been hypothesized that mating system variability in these animals is due to the high rate of twinning and relatively large size of newborns.
Alloparenting and allogrooming are also observed in callitrichines. Mating status does have some effect on rate and direction of allogrooming. Breeding males and females receive more grooming than other members of the group. Non-breeding females as well as non-breeding males are observed copulating, which can make it hard to determine which mating system is most common in Callitrichinae.
Mating System: monogamous ; polygynandrous (promiscuous) ; cooperative breeder
Research on reproductive behavior has not been done on gold-and-white marmosets. Other members of the subfamily Callitrichinae breed year round due to the abundance of gum, which is a staple in their diet. After mating, females have a gestation period of from 130 to 170 days. Females almost always give birth to twins. Twins make up roughly 19 to 25 percent of their mothers weight at birth. This is rare for Primates and can explain the cooperative breeding strategy that marmosets use. The rearing of young is shared by members of the group and the young will begin to be weaned at around 2 months old. Young will reach sexual maturity between 12 and 18 months but will not reach adult size for another year.
Breeding interval: Gold-and-white marmosets breed twice a year.
Breeding season: Gold-and-white marmosets breed throughout the year.
Average number of offspring: 2.
Range gestation period: 130 to 170 days.
Range age at sexual or reproductive maturity (female): 12 to 18 months.
Range age at sexual or reproductive maturity (male): 12 to 18 months.
Key Reproductive Features: iteroparous ; year-round breeding ; gonochoric/gonochoristic/dioecious (sexes separate); sexual ; fertilization ; viviparous
Although not much information is known on parental investment in gold-and-white marmosets, there is some information from other species in Callitrichinae. When females give birth, it is usually to a set of twins. From birth, both mothers and fathers care for the young.
Alloparenting is seen in species of Callitrichinae. There are many possible explanations for this, including the small size of the mother, and the fact that males through courtship ensure they will breed again. It is also observed that the more experience a juvenile has in carrying infants, the better his/her chances of breeding successfully in the future. Alloparenting allows young to learn how to interact socially with the group from grooming to play and other social activities. The parents provide everything from food to protection from predators.
Parental Investment: altricial ; pre-fertilization (Provisioning, Protecting: Female); pre-hatching/birth (Provisioning: Female, Protecting: Female); pre-weaning/fledging (Provisioning: Male, Female, Protecting: Male, Female); pre-independence (Provisioning: Male, Female, Protecting: Male, Female); post-independence association with parents; extended period of juvenile learning

Das Gelbweiße Seidenäffchen (Mico chrysoleucos, Syn.: Mico chrysoleuca, Mico chrysoleucus, Callithrix chrysoleuca) ist eine Primatenart aus der Familie der Krallenaffen.
Gelbweiße Seidenäffchen erreichen eine Kopfrumpflänge von 20 bis 24 Zentimetern, hinzu kommt noch der 30 bis 36 Zentimeter lange Schwanz. Ihr Fell ist vorwiegend weiß gefärbt, die Vorderpfoten, der hintere Teil des Rumpfes, die Hinterbeine und der Schwanz sind orange-gelb. Das fleischfarbene Gesicht ist unbehaart, an den Ohren befinden sich weiße Büschel. Wie bei allen Krallenaffen befinden sich an den Fingern und Zehen (mit Ausnahme der Großzehe) Krallen statt Nägeln.
Gelbweiße Seidenäffchen bewohnen ein kleines Gebiet im Amazonasbecken im brasilianischen Bundesstaat Amazonas. Die genauen Ausmaße des Verbreitungsgebietes sind nicht bekannt, es liegt südlich des Amazonas und östlich des Rio Madeira. Lebensraum dieser Art sind Regenwälder.
Diese Primaten sind tagaktive Baumbewohner. Sie bewegen sich auf allen vieren oder springend fort. Die Lebensweise ist nicht genau bekannt, vermutlich leben sie wie andere Marmosetten in Gruppen, die um ein ausgewachsenes, fortpflanzungsfähiges Paar organisiert sind. Gelbweiße Seidenäffchen nehmen in stärkerem Ausmaß als andere Seidenäffchen Früchte zu sich und haben darum auch größere Reviere. Daneben verzehren sie auch Baumsäfte und Kleintiere wie Insekten.
Auch aufgrund der Unklarheiten über das Verbreitungsgebiet lassen sich keine Angaben über den Gefährdungsgrad machen. Die IUCN listet die Art unter „zu wenig Daten vorhanden“ (data deficient).

Golden-white tassel-ear marmoset, gold-and-white marmoset. Sagüi (Brésil).
Nord du Brésil au sud du Rio Madeira. Une étroite zone verticale délimitée à l’ouest par le bas Rio Madeira puis le bas Rio Aripuanã, à l’est par le Rio Urariá-Canumã, au nord par l’Amazone et au sud par la confluence des Rios Aripuanã et Roosevelt.
Robe soyeuse et brillante. Dessus blanc. Dessous jaune crème à orangé pâle. Extrémité des membres variant du doré pâle à l’orange. Queue jaune donnant la (fausse) impression d’être annelée. Tête blanche. Touffes de poils blanc jaune sur les oreilles. Avec sa face rose et nue, il ressemble fort au Ouistiti blanc-doré (C. leucippe), mais ce dernier a les oreilles nues et une queue nettement moins touffue.
Diurne et arboricole.
Évolue entre 10 et 20 m de hauteur, abandonnant les étages supérieurs de la forêt aux atèles et lagotriches.
Frugivore, gommivore et insectivore. Consomme de nombreux fruits, ceux des figuiers, des muscadiers et des petits citronniers ainsi que des noix de cajou. Le fruit du guarana, à l’enveloppe rose et à la chair blanche, ressemble à un letchi. Sa pulpe est bourrée de caféine (quatre fois plus que dans le café) et lui donne du tonus. Blattes traquées dans la litière. Larves géantes de scarabée sous l’écorce dans le bois pourri, tuées en leur broyant la tête, une technique que les ouistitis utilisent pour toutes leurs victimes : riches en protéines, ces gros vers blancs dont les indiens se délectent également obligent les singes à aller au sol et augmentent sensiblement les risques de prédation. C’est donc un luxe qu’ils ne peuvent se payer que de temps en temps. Avale une couleuvre par les deux bouts, comme on partagerait une banane. Se désaltère dans les creux des arbres et c’est une aubaine quand l’eau de pluie s’y mêle à la sève.
Petits félins, rapaces, boa, mygale (pour les jeunes).
Néant.

Lo uistitì bianco-oro (Callithrix chrysoleuca Wagner, 1842) è un primate platirrino della famiglia dei Cebidi.
Veniva un tempo classificata come sottospecie di Callithrix humeralifera (C. humeralifer chrysoleuca nella vecchia denominazione).
Vive nella foresta amazzonica lungo il basso corso della riva destra del Rio Madeira, poco prima della sua immissione nel Rio delle Amazzoni.
Misura circa 55 cm di lunghezza (di cui più di metà metà spettano alla coda), per un peso che probabilmente raggiunge i 400 g: questi animali non sono stati infatti mai pesati finora, in quanto ritenuti sottospecie e quindi non studiati nei particolari.
Il colore del mantello va dal giallo pallido all'arancione. La faccia è glabra e rosata, mentre sulle orecchie sono presenti ciuffi di pelo bianco.
Si tratta di animali diurni ed arboricoli: vivono in gruppi che contano da otto a venti individui, a seconda della disponibilità di cibo. Quest'ultima è determinante anche per quanto riguarda le dimensioni del territorio, che possono variare fra i 100.000 e i 400.000 km². Si calcola che questi animali esplorino giornalmente un terzo del proprio territorio.
Sovrapponendosi i territori dei vari gruppi, questi animali sono soliti lasciare tracce odorose strofinando particolari ghiandole pubiche sui rami od urinando nei buchi che scavano nelle cortecce per ricavare il cibo.
Si tratta di animali animali principalmente resinivori, ossia si nutrono di linfa e gommoresina, che ricavano incidendo la corteccia degli alberi coi particolari incisivi. Possono nutrirsi anche di frutta, nettare e insetti.
Al momento non sono stati ancora effettuati studi specifici sui costumi sociali e riproduttivi di questa specie: si pensa tuttavia che le sue modalità riproduttive non differiscano di molto, sia nei modi che nei tempi, da quelle di altre specie congeneri.
