In areas where the habitat of Michoacan pocket gophers is encroached upon by people, usually for agricultural purposes, it has been known to cause damage to crops such as potatoes, corn, and wheat. Generally it is not in populated areas and causes little disturbance to people.
Negative Impacts: crop pest
Michoacan pocket gophers are listed as endangered on the IUCN Red list due to extreme habitat fragmentation, a decline in the population of mature individuals due to competition with aggressive pocket gophers, and a decline in the quality of habitat. It is not listed on the US Federal list or CITES list.
No specific list of predators could be found for Michoacan pocket gophers. In general pocket gophers are preyed upon a number of species which include badgers, domestic dog, weasels, bobcats, several snake species, skunks, house cats, foxes, coyotes, and several species of hawks and owls. As it was noted before Michoacan pocket gophers spends very little of its life above ground, this would severely limit opportunity for predators such as bobcats, dogs, coyotes, and raptors to prey upon it. Thus the lifestyle of Michoacan pocket gophers acts as a form of anti-predator adaptation.
Known Predators:
In general, pocket gophers are considered medium sized rodents; they have small eyes and external ears, a small, flattened head, short necks, fusiform shaped bodies, their fore paws have large claws, and their short tails are sparsely haired or naked. All gophers have external cheek pouches that are fur-lined and used to transport food through their burrows. To keep soil from getting into their mouth they have skin that grows behind their incisors. The length of Michoacan pocket gophers varies from 290 to 370mm and they typically weigh around 545 grams. Males and females are very difficult to tell apart from each other though males tend to be larger.
Their large incisors each have two grooves and grow continuously; they must gnaw consistently to keep them at the appropriate length. Michoacan pocket gophers have a number of physical characteristics that distinguish it from other pocket gophers. It is smaller than Llano pocket gophers, which inhabit similar habitat. Michoacan pocket gophers have small, deep-set eyes and short, dark grey to brown fur – similar to that of a mole. The fur on the dorsal side of its hind legs is lighter in color (grey to white), they can also have a white patch of fur on their throat. It has a hairless tail, and behind the rhinarium, on the rostrum, there is a hairless pad-like structure.
Average mass: 545 g.
Range length: 290 to 370 mm.
Sexual Dimorphism: sexes alike; male larger
Other Physical Features: endothermic ; bilateral symmetry
No specific information on the longevity of Michoacan pocket gophers could be found. Pocket gophers, in general, tend to have a lifespan of 1 to 3 years in the wild. In many species females are significantly longer lived.
Typical lifespan
Status: wild: 1 to 6 years.
Michoacan pocket gophers are found in pine-spruce-alder forests with friable soil at elevations between 2200 and 3600 meters. Excavations of their burrows have shown that the central burrow, and likely their nesting chamber, tends to be about two meters below the surface. Lateral tunnels, used for foraging, tend to be 20 to 30 centimeters below the ground. Unlike other pocket gophers, which will forage for food above ground near their burrow openings, Michoacan pocket gophers appear to be entirely subterranean.
Range elevation: 2200 to 3600 m.
Range depth: 0.2 to 0.3 m.
Habitat Regions: temperate ; terrestrial
Terrestrial Biomes: forest
No information could be found on specific forms of communication used by Michoacan pocket gophers. Its life underground has led to reduced eyes and ears and enhanced olfactory and tactile senses. It is likely these are the senses it uses to perceive its environment and to communicate with others.
Perception Channels: visual ; tactile ; acoustic ; chemical
Michoacan pocket gophers (Zygogeomys trichopus) are endemic to Mexico and are found in only four areas of the Sierra Madre of Michoacan; Nahuatzen, Cerro Patamban, Patzcuaro, and Cerro Tancitaro. In Nahuatzen, habitat destruction caused by an increase in agriculture has allowed more aggressive pocket gophers to encroach on its territory. More aggressive pocket gophers have appeared to have out-competed Michoacan pocket gophers in this area as no specimens have been reported from this area recently. Similar deforestation is occurring in the western parts of Cerro Tancitaro and eastern Patzcuaro and pocket gopher habitat is expanding in these areas as well, increasing the chance of Michoacan pocket gophers being extirpated from these areas, as well.
Biogeographic Regions: nearctic (Native ); neotropical (Native )
No information could be found on the specific diet of Michoacan pocket gophers, however pocket gophers in general are strict herbivores. They eat a variety of different plants and plant parts, including; stems, corms, forb shoots, tubers, roots, grass shoots, rhizomes, seeds, nuts, and stolen. It has been speculated that unlike other pocket gophers Michoacan pocket gophers do not leave their burrow to forage and are instead entirely subterranean. This would limit their diet to subterranean plant tissues. Pocket gophers, such as Chiriqui pocket gophers, which are closely related to Michoacan pocket gophers, are known to cache food when supply is high. Michoacan pocket gophers may also display this behavior.
Plant Foods: roots and tubers; wood, bark, or stems; seeds, grains, and nuts
Foraging Behavior: stores or caches food
Primary Diet: herbivore (Lignivore)
No information could be found specifically for the ecological role that Michoacan pocket gophers play in their environment; the information provided here is about pocket gophers in general. Animals such as mice, snakes, weasels, lizards, toads, and salamanders use abandoned burrows as refuges from predators and the weather. Pocket gophers are an important food source for many different species of predators. They continuously turn the soil, increase fertilization (via bury vegetation and feces), and aerate the soil, increasing its overall quality. Finally, burrows at higher elevations catch water from rainfall and snowmelt and hold onto it, decreasing soil erosion. Pocket gophers are also the obligate host of chewing lice (Geomydoecus and Thomomydoecus)
Ecosystem Impact: disperses seeds; creates habitat; soil aeration
Mutualist Species:
Commensal/Parasitic Species:
The action of their tunneling causes pocket gophers to increase soil porosity, promote the mixing of soil chemicals, and decrease water runoff. Humans benefit from all of these actions.
Unlike other species of pocket gopher the surface mound Michoacan pocket gophers create is unique. They are volcano shaped, lack a terminal opening and/or plug, have a more conical shape, and are significantly taller than the mounds of other species. The uniqueness of the mound of Michoacan pocket gophers may be evidence of it having habits that differentiate it from other species of pocket gophers.
Very little is known about reproduction of Michoacan pocket gophers. Information on the breeding season of Michoacan pocket gophers is very limiting. A single pregnant female carrying one embryo was captured mid-December and the testes of males caught in March and August were around three times smaller, less than 5 mm, than the testes of males caught in December, greater than 14 mm. They are thought to be polygynous.
Mating System: polygynous
Michoacan pocket gophers are solitary and likely territorial aside from when they mate or when females are rearing their young. It is unknown when the breeding season is or if they breed year round. Gestation, weaning periods, and age at sexual maturity are also unknown.
Breeding interval: The breeding frequency of Michoacan pocket gophers is currently unknown.
Breeding season: The mating season of Michoacan pocket gophers is currently unknown.
Range number of offspring: 1 (low) .
Key Reproductive Features: iteroparous ; gonochoric/gonochoristic/dioecious (sexes separate); sexual ; viviparous
Pocket gopher pups are altricial so some form of parental care, provided solely by the female, is required. The extent of this care and how long it’s provided for is unknown in Michoacan pocket gophers as all of it occurs two meters below the ground in the nesting chamber.
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); pre-independence (Provisioning: Female, Protecting: Female)
Zygogeomys trichopus és una espècie de rosegador pertanyent a la família Geomyidae.[2]
Viu per damunt dels 2.200 m d'altitud i prefereix els sòls d'alta muntanya coberts de pins, avets i verns.[3][4]
És un endemisme de la rodalia del llac Pátzcuaro (Michoacán, Mèxic): concretament, del Cerro Tancitaro, el Cerro Patamban, Nahuatzen i Pátzcuaro.[5][6]
L'expansió agrícola a la zona s'ha traduït en l'eliminació d'algunes zones forestals dins de l'àrea de distribució d'aquesta espècie. No obstant això, les seves principals amenaces són la competència amb Cratogeomys (el qual s'ha mogut a altituds més altes com a conseqüència de la destrucció dels boscos en els vessants més baixos), el fet d'ocupar un territori de només 5.000 km² i el seu hàbitat tan fragmentat.[7][3]
Tuza oder Michoácan-Taschenratte (Zygogeomys trichopus) ist ein Nagetier in der Familie der Taschenratten und die einzige Art der Gattung Zygogeomys.[1]
Mit einer Kopf-Rumpf-Länge von 20 bis 25 cm sowie einer Schwanzlänge von 9 bis 12 cm zählt die Art zu den größeren Taschenratten. Das Fell der Oberseite ist dunkelgrau bis braun, wobei eine leichte rostfarbene Schattierung vorkommen kann. Auf der Unterseite hat das Fell eine bleifarbene bis rotbraune Färbung. Kennzeichnend sind ein weißer Fleck auf der Kehle, eine nackte Stelle auf der Schnauze sowie hellgraue oder weiße Haare auf der Oberseite der Hinterfüße. Diese Taschenratte besitzt einen nackten Schwanz und zwei Rillen in den oberen Schneidezähnen.[2]
Die Art kommt mit mehreren voneinander getrennten Populationen im Gebirge Sierra Madre del Sur im mexikanischen Bundesstaat Michoacán vor. Sie lebt in Regionen die 2200 Meter über dem Meer oder höher liegen. Als Lebensraum dienen Mischwälder in denen Fichten, Kiefern und Erlen dominieren.[3]
Die Michoácan-Taschenratte gräbt unterirdische Tunnelsysteme deren zentrale Kammer 2 Meter oder tiefer unter der Oberfläche liegt. Sie verschließt den ursprünglichen Eingang mit einem hohen Erdhügel, der in seiner Form an einen Vulkan erinnert. Danach wird die Spitze des Erdhügels nicht mehr als Ausgang genutzt und der „Vulkan“ bleibt permanent verschlossen. Ein aufgefundenes Weibchen war mit einem Embryo trächtig.[2]
Waldrodungen in Zusammenhang mit der Anlage neuer Landwirtschaftsflächen führten zur Verkleinerung des Verbreitungsgebietes. Eine größere Bedrohung stellt die Konkurrenz mit Taschenratten der Gattung Cratogeomys dar, die ihrerseits aus tieferen Bereichen des Gebirges vertrieben wurden. Die IUCN listet die Michoácan-Taschenratte aufgrund des geringen Verbreitungsgebiets, das zusätzlich fragmentiert ist, als stark gefährdet (Endangered).[3]

The Michoacan pocket gopher (Zygogeomys trichopus) is a species of rodent in the family Geomyidae.[2] It is monotypic within the genus Zygogeomys.[3] It is endemic to Mexico where its natural habitat is temperate, high-altitude forests. Its numbers are declining and it is listed by the IUCN as "endangered".[1]
The Michoacan pocket gopher is a small animal with short, dense, black, lustrous fur and a hairless tail. The eyes are small and deep-set and there is a pad-like region of bare skin just behind the nostrils. It is docile when caught, making no attempt to bite as do other pocket gophers.[4]
The Michoacan pocket gopher is endemic to the Trans-Mexican Volcanic Belt mountain range in central southern Mexico, where it occurs in four discrete locations near west of Lake Pátzcuaro at altitudes over 2,200 metres (7,200 ft).[1][3] The fossil record shows that members of the genus Zygogeomys, including two other now extinct species, were widespread in the late Pliocene epoch in the southwestern United States. Its typical habitat is mixed forests of spruce, pine, and alder with deep friable soil suitable for burrowing. A number of small populations separated by unsuitable terrain exist. The species shows little genetic variation and the present population may be a relict of a previous, more widespread distribution.[3]
The Michoacan pocket gopher lives in a burrow and throws up a characteristic, cone-shaped mound of soil on the surface with no visible entrance. A central chamber has been found 2 m (6 ft 7 in) underground and may be where the young are raised. Little is known of the animal's breeding habits, which may be seasonal, as males caught in March and August had small testes while one caught in December had large ones. A pregnant female containing one embryo has been caught in December.[3] This animal is seldom caught in surface traps[3] and it may live and forage almost entirely underground.[4]
In its natural habitat of Michoacán, the pocket gopher has been reported to cause damage to avocado trees and mutilate young trees in reforestation projects, as well as wreak structural damage on roads, building sites, and irrigation canals.[5]
The habitat requirements of the Michoacan pocket gopher are very specific, and where agriculture replaces the native woodland in which it lives, it is restricted to higher altitudes and tends to be replaced by other species of pocket gopher (Pappogeomys).[6] Its total area of occurrence is less than 5,000 km2 (1,900 sq mi), its range is fragmented, and its population is declining, and the IUCN has listed it as "endangered".[1]

La tuza de Michoacán (Zygogeomys trichopus) es una especie de roedor de la familia de los geómidos y la única representante del género Zygogeomys. Es endémica de México y sólo se distribuye en zonas templadas del norte del estado de Michoacán.
Los individuos adultos miden en promedio entre 32 y 34 cm; las hembras son ligeramente más pequeñas que los machos. La cola mide 10 u 11 cm. El pelaje es gris muy oscuro, iridiscente. Tienen ojos muy pequeños debido a sus hábitos subterráneos. Otra característica distintiva es la presencia de una zona desnuda en el rostro; la cola es casi desnuda.
Construyen sus galerías hasta 2 m por debajo de la superficie, y al excavar sus galerías producen un montículo cónico característico, de poco más de 2 m de altura. No salen de sus túneles, por lo que son difíciles de observar. Habitan en bosques de pino, pero también en campos de cultivo, a alturas promedio de 2 000 sobre el nivel del mar en el Eje Neovolcánico. Se ha registrado en cuatro áreas: cercanías del Pico de Tancítaro, en el Cerro Patamban, en Nahuatzen y en Pátzcuaro. Por lo limitado de su distribución, la Unión Internacional para la Conservación de la Naturaleza la considera una especie en peligro de extinción.

Zygogeomys trichopus est une espèce de rongeur de la famille des Geomyidae, la seule du genre Zygogeomys. Endémique du Mexique, son habitat naturel est dans les forêts tempérées où l'espèce est en danger de disparition. Ce rongeur est appelé parfois « Rat à poche mexicain » de l'anglais Michoacan Pocket Gopher, ce qui peut prêter à confusion avec le Rat à poche mexicain (Cratogeomys castanops)[1].
Ce genre monotypique et l'espèce ont été décrits pour la première fois en 1895 par le zoologiste américain Clinton Hart Merriam (1855-1942).

Il tuza (Zygogeomys trichopus Merriam, 1895) è un roditore della famiglia dei Geomidi, unica specie del genere Zygogeomys (Merriam, 1895), endemico del Messico.[1][2]
Roditore di grandi dimensioni, con la lunghezza della testa e del corpo tra 200 e 250 mm, la lunghezza della coda tra 90 e 120 mm, la lunghezza del piede tra 38 e 48 mm, la lunghezza delle orecchie tra 5 e 9 mm e un peso fino a 580 g.[3]
Il cranio è lungo e stretto e presenta un rostro lungo e stretto, le arcate zigomatiche complete e la mandibola lunga e sottile. Gli incisivi superiori sono attraversati anteriormente da due solchi longitudinali. Sono caratterizzati dalla seguente formula dentaria:
3 1 0 1 1 0 1 3 3 1 0 1 1 0 1 3 Totale: 20 1.Incisivi; 2.Canini; 3.Premolari; 4.Molari;La pelliccia è corta e fine, più di qualsiasi altro gopher e dona un'apparenza brillante anche più di quella della talpa. Le parti dorsali variano dal grigio fumo al marrone, mentre le parti ventrali sono più chiare, spesso con delle macchie biancastre irregolari specialmente sulla gola. Sopra il naso è presente un cuscinetto carnoso privo di peli e circondato lateralmente e superiorimente da una sottile banda di peli completamente bianchi. La coda è completamente priva di peli, biancastra e quasi trasparente. Il cariotipo è 2n=40 FN=74.
È una specie fossoria, che produce tumuli alti fino a 23 cm di forma conica privi della caratteristica entrata in cima e con nidi a circa 2 m di profondità. Sono alquanto docili.
Una femmina gravida con un singolo embrione è stata catturata a metà dicembre.
Questa specie è conosciuta soltanto nelle vicinanze del Lago Patzcuaro, nella parte centro-settentrionale dello stato messicano di Michoacán.
Vive in zone aperte all'interno di pinete ed abetaie tra 2.000 e 3.000 metri di altitudine.
La IUCN Red List, considerato l'areale inferiore a 5.000 km², la popolazione concentrata in sole sei località, l'ambiente seriamente frammentato, il continuo declino nella sua estensione e qualità e la riduzione del numero di individui maturi dovuta alla competizione, classifica Z.trichopus come specie in pericolo (EN).[1]

Michoacan-kindpåsråtta (Zygogeomys trichopus[2][3][4]) är en däggdjursart som beskrevs av Clinton Hart Merriam 1895. Zygogeomys trichopus är ensam art i släktet Zygogeomys som ingår i familjen kindpåsråttor.[5][6] Inga underarter finns listade.[5]
Denna kindpåsråtta blir 20 till 25 cm lång (huvud och bål) och därtill kommer en 9 till 12 cm lång svans.[7] Pälsen har på ovansidan en mörkgrå till brun färg. Kännetecknande är en vit fläck på bakkroppen och två rännor i varje övre framtand. Svansen är nästan helt naken.[7]
Michoacan-kindpåsråttan förekommer bara i ett mindre område i västra Mexiko. Arten vistas där i bergstrakter som ligger högre än 2200 meter över havet. Regionen är täckt av barrskog med några lövträd.[1]
Individerna bygger underjordiska tunnelsystem med flera kamrar. Största delen av boet ligger två meter under markytan. I motsats till andra kindpåsråttor gräver de inte i jorden nära markytan för att komma åt födan. De vandrar däremot på markytan. Födan utgörs av olika växtdelar.[7]
Annars är inget känt om levnadssättet.
Arten hotas av skogsavverkningar och etablering av jordbruksmark. Den får även nya konkurrenter då arter från släktet Cratogeomys, som vanligen lever i lägre regioner, flyttar till bergstrakterna på grund av habitatförstörelse i sina ursprungliga levnadsområden. IUCN listar Michoacan-kindpåsråttan som starkt hotad (EN).[1]
