We document 6 new "Mexicana desnuda" in the Lacandona rainforest, southern Mexico, and through interviews with local people, we assess potential threats for this species in the region.
Cabassous centralisCingulata, Dasypodidae, xenarthra, human perception. Cabassous centralis Miller, represents one of the least known Xenarthra of Mesoamerica. It is under this scenario that information about new records and an assessment of potential threats become highly valuable for their conservation. Here, we review historic occurrences of this species in Mexico, and document 6 new records of C. We also assess potential threats and provide additional information on human knowledge about this species in the region using interviews with local people.
The northernmost distribution of C. It occurs from sea level to around 3 m a. In Belize and Nicaragua C. In Costa Rica it is a rare species everywhere in the country, although it has been observed more frequently in lowland forest than in cloud forest above 1 m a. Genoways and Timm, In Chiapas, Mexico, it has been found in areas associated with tropical evergreen forest, grasslands, and transformed areas of secondary forest located below m a.
Its diet consists of termites, ants, and other invertebrates Carrillo et al. Scientific collections that were reviewed online include: In general, very few specimens have been reported in the scientific literature or deposited in museums.
The Smithsonian Institute Museum holds 14 specimens 4 from Colombia, 1 from Honduras, 6 from Panama, 2 from Venezuela, Mexicana desnuda 1 from an unknown locality. The only 3 specimens of C. The first record was in October The predominant vegetation near San Javier is tropical evergreen forest Rzedowski, After these records, there have been no
Mexicana desnuda reports of this species for this region, nor for Mexico. The first new record was collected on February 15th, Because the specimen was an advanced stage of decomposition, it was immediately buried and excavated 2 months later to recover the "Mexicana desnuda" and teeth.
The nearest Mexicana desnuda fragment ca. The second new record was a footprint of C. The footprint of C. The animal was feeding in a termite mound 20 cm above the ground. The individual was foraging with its head inserted into a deep hole 15 cm. The specimen was not sacrificed, but documented with photographs as evidence of the Mexicana desnuda Fig.
The individual was in an advanced state of decomposition and for logistical reasons it could not be buried and retrieved at a later date, so it was not collected. Nevertheless, we documented the specimen with photographs Fig. The area where the specimen was found was surrounded by agricultural fields and grasslands, and located approximately 3 m from MABR and m from the nearest forest fragment ca. The individual was a juvenile Mexicana desnuda it was being devoured by vultures Coragyps atratus.
The area where the specimen was found was surrounded by agricultural fields and approximately m from the town of Santa Rita, and m from the nearest forest fragment 15 ha. The sixth new record was a footprint of C. The footprint was found fresh in the morning It was easily identified using the figures of Arandabut we did not prepare a plaster mold of the footprint Mexicana desnuda logistical reasons. This fragment is mainly surrounded by pasture lands and secondary forests.
The nearest town is Loma Bonita ca. The area is located approximately m from the Lacantun River northern face and m from the Chajulillo river eastern face. To determine the extent to
Mexicana desnuda local people in the region are familiar with this species and to document their knowledge about its ecology, in November we conducted interviews with 20 residents in communities near the observation sites.
In Loma Bonita we did 9 interviews and in Boca de Chajul we did 11 interviews.
We restricted our surveys to adult men over 40 years old range 40 to years and all with more than Mexicana desnuda years of residency in the region. This group of people represents those who spend the most time working in the field and frequently have more knowledge about native wildlife Mexicana desnuda et al. All participants readily recognized the 2 species as distinct. The first question we asked was they had observed C.
If their answer was positive we asked how many times they had seen it, approximately how long ago they observed it, and features of the observation site. Finally, we asked if this species is hunted for food or otherwise used by the inhabitants of the region. Only 8 of the 20 interviewees reported having seen the species in the region, and in all cases they reported seeing the species on only 1 occasion.
Two reported seeing it 10 years Mexicana desnuda, 4 saw it 15 years ago and 2 saw it 20 years ago. Six of the 8 sightings occurred in the daytime and 2 were observed at night.
All interviewees claimed to have killed the armadillo immediately because they do not like the appearance of the animal and they do not use the meat because they believe it is poisonous. None of the interviewed persons Mexicana desnuda offspring during their encounters with the armadillo. In spite of
Mexicana desnuda fact that several academic institutions e. The interviews also suggest that this species is very rare, because although we selected people who spend most of their time in the field, most records of this species were made more than 10 years ago.
In addition to being locally rare, there are other characteristics of the species that increase their vulnerability to extinction. In particular, data from the interviews show that in this region this species of armadillo is Mexicana desnuda to be poisonous, and it is killed every time it is encountered.
Future studies should focus on developing projects of environmental education with the aim of helping to change the perception that people have toward this species. However, Forman and Alexander emphasize that the effect of road mortality on wildlife populations may be restricted primarily to a few rare species. We suggest that future studies further evaluate this Mexicana desnuda over the entire range of this species.
