The hidden anatomy of paranasal sinuses reveals biogeographically distinct morphotypes in the nine-banded armadillos ([i]Dasypus novemcinctus[i])

چکیده
Background. With their Pan-American distribution, long-nosed armadillos (genus Dasypus) constitute an understudied model for Neotropical biogeography. This genus currently comprises seven recognized species, the nine-banded armadillo (D. novemcinctus) having the widest distribution ranging from Northern Argentina to the South-Eastern US. With their broad diversity of habitats, nine-banded armadillos provide a useful model to explore the effects of climatic and biogeographic events on morphological diversity at a continental scale.

متن کاملBeyond the carapace: skull shape variation and morphological systematics of long-nosed armadillos (genus [i]Dasypus[i])
Background. The systematics of long-nosed armadillos (genus Dasypus) has been mainly based on a handful of external morphological characters and classical measurements. Here, we studied the pattern of morphological variation in the skull of long-nosed armadillos species, with a focus on the systematics of the widely distributed nine-banded armadillo (D. novemcinctus). Methods. We present the fi...

متن کاملDetection of Mycobacterium leprae DNA in nine-banded armadillos (Dasypus novemcinctus) from the Andean region of Colombia.
OBJECTIVE To use DNA detection methodologies to test for M. leprae in nine-banded armadillos inhabiting forested regions located around the cities and towns where leprosy patients have been identified. DESIGN Ear lobe biopsies of 22 nine-banded armadillos were studied during a 2 year period. The biopsies were processed for DNA extraction and amplification by nested polymerase chain reaction (...
متن کاملRecords of Nine-Banded Armadillos, Dasypus novemcinctus, in Illinois
The nine-banded armadillo, Dasypus novemcinctus, has been expanding its range in the United State since the mid-1800s. There had been sporadic reports of this species in Illinois prior to 1990. I conducted a mail survey in 2003 of individuals knowledgeable about the fauna of southern Illinois to investigate the possible expansion of the armadillo into the state. I also sent questionnaires to an...
