“…(e) Distribution Paucidentomys is known only from montane forest on Mount Latimojong and the transition between lowland and montane forest on Mount Gandangdewata, but probably occurs more broadly in mid-to highelevation areas. The species may be endemic to the southwestern mountains of central Sulawesi [15].…”

Rodents are important ecological components of virtually every terrestrial ecosystem. Their success is a result of their gnawing incisors, battery of grinding molars and diastema that spatially and functionally separates the incisors from the molars. Until now these traits defined all rodents. Here, we describe a new species and genus of shrew-rat from Sulawesi Island, Indonesia that is distinguished from all other rodents by the absence of cheek teeth. Moreover, rather than gnawing incisors, this animal has bicuspid upper incisors, also unique among the more than 2200 species of rodents. Stomach contents from a single specimen suggest that the species consumes only earthworms. We posit that by specializing on soft-bodied prey, this species has had no need to process food by chewing, allowing its dentition to evolve for the sole purpose of procuring food. Thus, the removal of functional constraints, often considered a source of evolutionary innovations, may also lead to the loss of the very same traits that fuelled evolutionary diversification in the past.

“…For our purposes here it excludes the coastal strip along the shores of the Makassar Strait simply because no nonvolant mammals have been collected there. A suite of mammals, from shrews to rats, have been collected only in the west-central region: a few species are found in tropical lowland evergreen rain forest covering lower altitudes on foothills and in valleys, but most occur at higher altitudes in montane forests (Musser et al, 2010).…”

“…This question can be The principal hosts of fleas belonging to the genus Farhangia are considered to be tree squirrels, and most other specimens of F. quattuordecimdentata have been collected from the endemic Sulawesi pygmy tree squirrel Prosciurillus murinus (see Musser et al, 2010). However, in addition to E. centrosa, this flea has been recorded from another endemic Sulawesi rodent, the murid Margaretamys beccarii.…”

“…The sucking louse associated with Echiothrix centrosa is no exception. As with the endemic hoplopleurid sucking lice that parasitize endemic sciurids on Sulawesi (Musser et al 2010), there has probably been much phyletic tracking of murid hosts by sucking lice in Sulawesi as ancestral murids diverged into new taxa. With respect to the current study, Polyplax melasmothrixi, which uniquely parasitizes Melasmothrix naso on Sulawesi, has distinct morphological similarities with two undescribed species of Polyplax that parasitize the two species of Tateomys listed in table 18.…”

“…Because of the intimate bond between parasite and the parasitized, morphological and eventually molecular comparisons among the Polyplax residing on different species of Echiothrix might add another set of data potentially useful for discerning species limits of the hosts. In the meantime, the new record broadens the inventory of sucking louse species (in Polyplax and Hoplopleura) found on endemic Sulawesian rodents in general (Musser et al, 2010) and murines in particular (Durden, 1986a(Durden, , 1986b(Durden, , 1987(Durden, , 1990Musser, 1991, 1992;Musser and Durden, 2002).…”

Behaviors associated with vocal communication of squirrels

Vocal communication is an important method squirrels (Sciuridae) use to transfer information from one individual to others. While behaviors associated with vocal communication have been explored in individual species or single call-types in specific groups of squirrels, no comprehensive review of these behaviors exists for Sciuridae. Herein, I review the current literature to describe behaviors associated with vocal communication in three groups of squirrels: ground squirrels, tree squirrels, and flying squirrels. I discuss the behavioral functions of squirrel vocalizations. A wide variety of behaviors are associated with particular call-types produced by squirrels, including alarm, agonistic, discomfort, affiliative, mating, and neonatal calls. There are large knowledge gaps in cataloging the vocal repertoires and associated behaviors of many species of squirrels, including commonly studied species such as marmots and ground squirrels, as alarm calls are typically focused on and other call-types are understudied or ignored. Since vocal communication is important to the development, reproduction, and survival of squirrels, further understanding the biological and ecological drivers behind vocal repertoires is critical to evaluating the ethology of this family as a whole.
