Morphological variability in long-distance subject-verb agreement: A study of native and nonnative processing
This study examined morphosyntactic variability in Spanish-speaking learners of English in order to determine the effects of two linguistic factors on the establishment of subject-verb agreement: structural distance and plural markedness. The study also investigated the effects of task demands on …

Single-cell morphological data reveals signaling network architecture
… to extract information from highthroughput morphological data from genetic screens. Our contributions fall into three major categories. 1) To define and apply robust statistical measures to identify genes regulating morphological variability. We develop and thoroughly test methods for …

Investigation of Craniofacial Morphological Variation at Sully (39SL4)
… genetics to identify factors contributing to the morphological variability between multiple, geographically distinct burial areas associated with the Sully village site (39LS4) in the Middle Missouri region of South Dakota. In particular three burial areas at Sully (A, D, and E) provide adequate …

Ecological, Evolutionary, and Taphonomic Comparisons of Brachiopods and Bivalves at Multiple Spatial and Temporal Scales
… of an extant brachiopod with respect to morphological variability is studied using geometric morphometrics. The results from several analyses confirm a high degree of morphological variability with little change in mean shape between the living and sub-fossil assemblage. Additionally, …

Electrophoretic, Morphometric, and Meristic Comparisons of Walleye Broodstock in South Dakota
Electrophoretic and morphological variability among walleyes collected from three upper Missouri River tributaries and a glacial lake in South Dakota was investigated, and an upper Mississippi River stock was electrophoretically compared to the South Dakota stocks. Allele frequencies of two (MDH-3, …

Risk stratification of ICU patients using arterial blood pressure waveforms
… of risk stratification such as T wave Alterans, Morphological Variability, and Heart Rate Variability extract prognostic information from the electrocardiograph. However, there is still a wealth of data collected from ICU patients and left unused every year that can augment risk-stratification …

Spatial and temporal scales of the morphodynamic evolution within the Studland complex.
… has been reviewed. In addition,the temporal variability of the beach system between 2001 and 2004 has been examined. These objectives have been combined to produce a nested hierarchy of spatial and temporal change in the Studland system in order to re-evaluate already existing conceptual …

Variação morfológica dos esqueletos de Montastraea cavernosa (Linnaeus, 1767) e Favia gravida Vernill, 1868 (Cnidaria, Scleractinia)
Morphological variability is a widespread but poorly understood characteristic of many colonial animals. Skeletal variations of Montastraea cavernosa from Brazil, Abrolhos (BA), Tamandaré (PE) and Mexico, Puerto Morelos (Q.ROO) and variations of Favia gravida from Brazil, Abrolhos, Tamandaré and …

EVOLUTIONARY RELATIONSHIPS IN POLYGONEAE RCHB. (POLYGONACEAE) WITH AN EMPHASIS ON THE AMPHI-PACIFIC MUEHLENBECKIA MEISN.
… included in <em>Polygonum</em> as morphological studies suggest? 4) Does the morphologically distinct <em>Oxygonum</em> that is restricted to Africa and for which there were no sequence data available prior to this study belong to Polygoneae? In addition, a species level study of …

Variabilidade morfológica e status taxonômico das amostras populacionais do gênero Clyomys (Rodentia: Echimyidae)
… examined in a more comprehensive analysis of the morphological variability of genus. Morphometric and qualitative analyses of skull morphology were confronted with the qualitative description of phallic morphology and pelage coloration, for a total of 112 specimens from 16 localities. The results …

Studies on the Biology of <i>Striga aspera</i> (Scrophulariaceae) in Nigeria
… information exists on its relationship with the morphologically similar and much studied S. hermonthica. Both species are sympatric in West Africa and if they hybridize, may serve as virulent gene reservoirs for each other.</p> <p>The primary focus of this study was on the biology of S. aspera in …

Paranthropus paradoxes: Patterns of morphological variation in East African 'robust australopithecines'
… record. Its early discovery, together with its morphological distinctiveness, have defined this genus as a unique hominin lineage parallel to our own. Paranthropus boisei, who lived in East Africa between 2.3 and 1.4 million years ago, stands out amongst ‘robust australopithecines’ for its hyper …

Of mice and hominins: using the craniomandibular morphology of hybrid mice to better understand hybrid morphologies in the Hominin fossil record
… sympatric non-hybridizing taxa) on the basis of morphological variability. In terms ofnon-metric cranial traits, hybrids are more likely to express unusual sutural anomalies and atypical bilateral foramina. Two specimens (intra-specific F1 and B1 individuals) showed extensive wormion bones. These …

The evolution and diversification of Pleistocene Homo
The morphologically diverse and geographically expansive Pleistocene Homo fossil record continues to be a topic of debate. Recent fossil discoveries have highlighted the diversity, as well as the difficulty of identifying evolutionary relationships, within our lineage. Previous studies have focused …
