LINE-1 repeats were shown to be involved in genome architecture and in the occurrence of chromosomal rearrangements in many vertebrates. We found bright LINE-1 probe signals at centromeric or pericentromeric areas, GC rich, on almost all chromosomes in three tamarin species. We also found non-centromeric signals along chromosome arms. In a phylogenetic perspective, we analyzed the pattern of LINE-1 distribution considering human chromosomal homologies and C banding patterns. Our data indicate that LINE-1 centromeric expansions and accumulation presumably arose in a common tamarin ancestor and that the presence of LINE-1 at the junction of human chromosome associations is presumably linked to interchromosomal rearrangements. For example, we found bright centromeric signals as well as non-centromeric signals on chromosomes 1 and 2, in all species analyzed, in correspondence to human chromosome associations 13/9/22 and 20/17/13, which are synapomorphic for all tamarins. Furthermore, we found other faint signals that could be apomorphisms linked both to intrachromosomal rearrangements as well as to retro-transposition events. Our results confirm that the three species have similar karyotypes but small differences in LINE-1 and heterochromatin amplification and distribution; in particular on chromosome pairs 19–22, where we show the occurrence of small inversions, in agreement with previous classic cytogenetic hypotheses.</p>","PeriodicalId":54751,"journal":{"name":"Journal of Zoological Systematics and Evolutionary Research","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2021-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44169289","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The cranial ontogeny has been studied in several mammals, but remains poorly studied in the group. We quantified the ontogenetic pattern for 22 sigmodontine species and 8 outgroups, generating partial reconstructions of ancestral allometric growth patterns, and testing the role of evolutionary history on cranial ontogeny. Sigmodontines were conservative in growth pattern, without unique patterns defining tribes. The allometric growth of the cranium was mostly negative, with Akodontini being the most isometric and Phyllotini the most allometric tribes. Allometry of variables associated with the neurocranium was mostly negative, while those linked to trophic functions showed positive allometry or isometry. A general cranial lengthening was detected, but variables associated with cranial width or height grew at lower rates. Cranial growth and development were associated with changes in the musculature functionally involved in bite and mastication. Most changes occurred in earlier postnatal stages, achieving an early morphological optimum. Few changes in the rate of growth at internal nodes were detected, and the stasis along the backbone was recurrent. Cranial elongation was a pattern widespread in the sample and likely a plesiomorphic condition. The few synapomorphies defining the ancestor of Sigmodontinae conform to a pattern with zygomatic arches little expanded laterally and globose braincases. The conservative pattern may be attributed to the biomechanically optimal morphology for omnivorous diets, suggesting that the generalized morphology allows the exploitation of multiple types of food with minor morphological adjustments.</p>","PeriodicalId":54751,"journal":{"name":"Journal of Zoological Systematics and Evolutionary Research","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2021-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44913107","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Exploring the morphology of this species offers the twofold opportunity to test the hypothesis of early onset of spatial sorting and to gather information on the dynamics of this unstudied biological invasion.

We did not detect evidence of spatial sorting in the morphological traits analyzed. Instead, morphological variation was largely dependent on sex and body size of individuals. Sexual dimorphism was limited in relation to other populations in the native range, and body size did not vary across the invasive gradient, which could indicate that both adults and juveniles are currently contributing to the dispersal in this invasive species.
