DOI: 10.1002/jmor.21331
Abstract: We present a topological analysis of the third upper molars (M3) using the recently developed ICAMER nomenclatural system as a way to understand the dental morphological similarity in sigmodontine rodents, the most speciose subfamily of… read more here.

DOI: 10.1139/cjz-2021-0042
Abstract: Information on dietary ecology plays a key role in a wide array of biological research and conservation decisions, but its availability is biased towards large and charismatic taxa, whereas small mammals are underrepresented. Of the… read more here.

DOI: 10.1515/mammalia-2019-0031
Abstract: Abstract We studied the enlargement of the upper third molar (M3), with respect to the upper second molar in sigmodontine rodents, the largest subfamily of living cricetids. M3 is enlarged in extant and extinct members… read more here.

DOI: 10.1515/mammalia-2019-0036
Abstract: Abstract Small mammal communities in the Neotropics are composed largely of sigmodontine rodents. However, many questions regarding these communities remain unanswered, especially those pertaining to fine-scale sympatry and habitat selection. To address this, we examined… read more here.

INTRASPECIFIC KILLING EVENTS IN SIGMODONTINE RODENTS (Oecomys cf. cleberi AND Oligoryzomys nigripes)
Sign Up to like & getrecommendations! Published in 2018 at "Oecologia Australis"
DOI: 10.4257/oeco.2018.2203.08
Abstract: Agonistic events can cause the death of one or more individuals involved and can be an important factor in population structure. The recording of these interactions between small mammals in situ is a difficult task.… read more here.
