“…In the teeth of the agouti (Fig. 1E), neither the crown nor the root can be distinguished because the enamel covers substantially the entire length of the tooth [24]. Besides, the Mundurucu decorate hair and ears with cotton cords embellished with red and black feathers of a black-billed toucan (Ramphastos vitellinus).…”

Trophy heads are human heads that have been removed from the rest of the body at the time of death or later. They present varied elaborations, to a greater or lesser degree: Basically the skull can be preserved (skull trophy) or not (shrunken head). We present here a morphological study that allows us to study the authenticity and possible cultural background of three trophy-heads belonging to the Complutense University's patrimony (Madrid, Spain) and rediscovered by serendipity. The aim/goal of this paper is twofold. First, study and identify of these trophy heads. Second, to assess their authenticity.We conclude that two out of the three heads are shrunken heads, suggesting that their objective/goal was different and that can be clearly distinguished from the false or commercial shrunken heads, that emerged mainly in the nineteenth century. Also, their morphological and ornamental characteristics indicate that one is authentic or ceremonial tsantsa and the other is commercial. The other head was a skull trophy with the ornamental decorative features compatible to a trophy head by the Mundurucu tribe.

“…The jaw could move forward and create two positions: one where the incisors occluded while the cheek teeth did not and another where the cheek teeth occluded but the incisors did not [ 24 ]. The agouti’s ( D. azarae ) premolars had a deciduous form followed by the permanent premolars, whereas molars had no deciduous form [ 25 ]. The same dental formula for an adult agouti was found ( D. prymnolopha ) with the teeth of the lower jaw larger than their corresponding upper ones [ 26 ].…”

This review highlights the available literature on the nutrition of six neo-tropical animals with the potential for domestication—the agouti (Dasyprocta leporina/D. aguti), lappe (Agouti paca), capybara (Hydrochoerus hydrochaeris), manicou/opossum (Didelphis marsupialis insularis), collared peccary (Peccary tajucu) and the red brokcet deer (Mazama americana). Over 100 references were used, spanning over 100 years. The earliest being 1915 and the most recent being 2018. The references used in this review were synthesized to give a detailed look of the dentition, anatomy of the gastrointestinal tract and type of feed these animals consume. Nutritional requirements of the animals are required to understand what is needed for growth, maintenance and reproduction of each physiological stage. The agouti (D. leporina/D. aguti) was observed to be a monogastric mammal that fed primarily on fruits, seeds, animal matter and practiced caecotrophy. The lappe/paca (C. paca/A. paca) was described as a strict herbivore and a frugivore which practiced caecotrophy, with a diet that varied throughout the year, according to food availability. The capybara (H. hydrochaeris) was found to be the largest known rodent and was described as a semiaquatic hindgut fermenter that practiced caecotrophy. The manicou/opossum (D. marsupialis insularis) was found to be an omnivore with a simple stomach. The collared peccary (T. tajacu) was found to be frugivorous. Their unique stomach enabled them to consume a wide variety of feedstuff, allowing them to be found in a wide range of habitats. The red brocket deer (M. americana), a ruminant, was described as a browser that consumed mainly fruits and seeds and they frequented mineral lick. Knowledge of what they consume in the wild is important, so that we know what to feed in captivity. There is also the need to evaluate captive diets while trying to domesticate these mammals and develop nutrient requirement tables for these neo-tropical animals. Finally, an understanding of the dentition and gastrointestinal tract is important to increase efficiency (nutritional and cost). These six neo-tropical mammals were chosen due to their prevalence as game species in Trinidad and Tobago.

“…The top of the head, neck, and middle of the back between the shoulders are sometimes dark with long bristles; the ears are small and bare, similar to the tail that is almost vestigial (Smythe, 1987;Emmons and Feer, 1997). In addition, they possess four long and curved incisor teeth, whose macroscopic characteristics reveal structure similar to that of other mammals (Oliveira et al, 2012). Between males and females there is no sexual dimorphism; therefore, to differentiate them, it is necessary to perform sexing through palpation, where the difference between the male's prominent penis and the female's two vaginal folds, forming the vulva, is easily observed (Guimarães et al, 2009).…”

“…Furthermore, the claws of the forelimbs are slightly arched, indicating the ability to excavate, although they are not true diggers. The hindlimbs are much larger than forelimbs, enabling them to jump (Oliveira et al, 2012).…”

Reproduction in agouti (Dasyprocta spp.): A review of reproductive physiology for developing assisted reproductive techniques

2018

View full text Add to dashboard Cite

Dasyprocta spp. (agouti) include wild rodents with highlighted ecological and economic importance, and are considered experimental models for endangered hystricognath rodents. Of late, development of techniques to conserve their genetic material as well as the formation of biobanks is increasing. In this context, this review describes the main advances in the knowledge of the reproductive morphophysiological specificities of agouti as well as the development and improvement of assisted reproductive techniques aimed at conservation, multiplication, and exploitation of their reproductive potential under captivity.
