Description:
The Santacrucian (early-middle Miocene) fauna is exceptional in its richness (over 70 species recorded in 21 stratigraphic levels). In this contribution we attempt a preliminary paleobiological characterization of the armadillos (Dasypodidae and Peltephilidae). Santacrucian Dasypodidae includes the genera Prozaedyus Ameghino, Proeutatus Ameghino, Stenotatus Ameghino, and Stegotherium Ameghino. The Peltephilidae include the genus Peltephilus Ameghino and others undergoing systematic revision. Body masses and locomotory habits are inferred from the sizes of the proximal and middle shaft dimensions of the limb bones from allometric equations and indices previously modeled in living dasypodids. Masticatory and dietary interpretations are based on the jaw mechanics, the analysis of the temporomandibular joint and mandibular symphysis, and the shape, arrangement and wear patterns of teeth. The body mass averages are 15.28 kg for Proeutatus, 3.72 kg for Stenotatus, 1.12 kg for Prozaedyus, 11.47 for Stegotherium, and 11.07 kg for Peltephilus. The diversity in limb bone proportions is not so marked as in the living species; forelimb indices reflect proportions similar to those of the living dasypodines and euphractines, all of whom are relatively good diggers. None of the Santacrucian taxa reach the degree of cursoriality of Tolypeutes Illiger, the extreme fossoriality of Priodontes F. Cuvier, or the subterranean habits of Chlamyphorus Harlan. Within a potentially generalized omnivory, some specializations can be easily detected within the Santacrucian armadillos: herbivory in Proeutatus and Peltephilus, and myrmecophagy in Stegotherium. This could help to explain the potential coexistence of so many genera in a single area, diminishing the degree of competition for resources. ... Read more

Book Description

Gale proudly presents the completely revised and updated version of the acclaimed Grzimek's Animal Life Encyclopedia set. Hailed by many as the best reference work on animals ever published, a legacy left to us by famed zoologist and animal lover Bernhard Grzimek, this set is renowned for its scientific reporting and coverage, and serves as a major point of reference for researchers, students, and those hoping to satisfy their curiosity about the animal kingdom. Information can be found on life cycles, predators, food systems, overall ecology and much more. Staying true to the original scientific pedigree, Gale enlisted prominent advisors and contributors from the international scientific community to incorporate recent developments in our knowledge of the animal world.

Description:
The maned sloth is a poorly known species endemic to the highly fragmented and disturbed Brazilian Atlantic forest. As this species has a strictly forest habitat and low dispersion ability, it is susceptible to local extinctions in small and isolated fragments. The project started in 1994, translocating stranded sloths found within or nearby urban zones into forest reserves located in Santa Teresa, state of Espi@?rito Santo. Five translocated, radio-collared adults were monitored monthly from periods lasting from 10 months to 3 years after release and data on activity budgets, diet, and home range size were analysed. Results showed that moving and feeding time and distances travelled daily were not significantly related to translocation time (i.e., time, in days, after release). One female, monitored for three years showed, however, a steady and significant decrease in time spent moving from the first to the second to the third year of monitoring (regression Analysis; p<0.05). The distances it travelled/day also decreased throughout this same period, but results were not significant (ANOVA; p>0.05). Sloths explored the area more intensively in the first 6 months after release, but minor changes in home ranges were detected even after 3 years. Results suggest that maned sloths are amenable to translocation experiments provided that source and release sites are floristic and ecologically similar. To fully access the success of such experiments though, it is recommended that sloths be monitored for periods longer than 1 year. ... Read more

What An Interesting Read!
This is a fine starter series for kids interested studying different animals.Anteaters, Sloths, and Armadillos is our most recent adventure with the wonderful and interesting Animals in Order series...what can I say, my kids just can't get enough of these!What I like a great deal about this is that it takes time at the beginning of the book to look at (briefly) what makes an animal a xenarthrans, specifically getting into what traits exactly make a xenarthran (when roughly translates into strange joint).The book then goes into the "order" of living things which details the kingdom, phylum and class , order, family and species (with a handy visual chart for reference, great for younger kids, so they can SEE how it works rather than just read it or have it read to them). This is one of the better features of this series.Next the text goes specifically into where xenarthrans fit into animal kingdom, breaking it down (in words and pictures again) to kingdom (animal), phylum (chordate), class (mammal) and order (xenarthran).

The book also talks a bit about where anteaters, sloths, and armadillos of all types and sizes fit into food chain and in habitats.Anteaters, Sloths, and Armadillos goes from there into an overview of fifteen species complete with full page, color photographs for each one, which really serve to bring the information to life.This section includes Family, Common Example, Genus and Species and Size for each animal discussed and each animal is given one full page for written description and one full page COLOR photo...excellent for fully engaging the reader!Animals included here are the giant anteater, southern tamandua, two-toes sloth, pale-throated three-toed sloth, nine-banded armadillo, pichi and more!

Overall, a fantastic way to introduce various types of artiodactyls to your curious young reader!What you get in Anteaters, Sloths, and Armadillosis an excellent overview of all types of zenarthrans.Additionally, at the end of the book are several pages of fun facts about sloths, anteaters and armadillos.As always with this series, I was pleased to find that at the end of the book the author/publisher also included a short recommended reading list and some really great web pages to do more research on...the kids in particular LOVED this! The books in this series would make a wonderful addition to a classroom library or as gifts for your favorite young reader who has a passion for animals; the information here is scientifically presented, accented with wonderful color photos and is both interesting and informative!
