Co-occurrence and phenological niche separation in rodent pollinated Proteaceae
… little or no work has been done on patterns of co-occurrence and flowering phenology. The presence of three potentially rodent-pollinated Protea species at Fernkloof Nature Reserve, two of which were observed to co-occur, facilitated the following questions: i) are P. cordata, P. scabra and P. …

Moose and deer resource selection and co-occurrence in northeast Minnesota
… tenuis, carried by white-tailed deer (Odocoileus virginianus) has often been cited as a significant factor contributing to moose (Alces alces) population declines. Moose suffer from neurologic disease and usually die when infected with P. tenuis. The strength of the three-way relationship …

Joint-stochastic Spectral Inference for Robust Co-occurrence Modeling and Latent Topic Analysis
Co-occurrence information is powerful statistics that can model various discrete objects by their joint instances with other objects. Transforming unsupervised problems of learning low-dimensional geometry into provable decompositions of co-occurrence information, spectral inference provides fast …

Ecological Conservatism and Traits Predict Introduction Risk and Co-Occurrence for the Flora of Chicago
… of plant species has changed the makeup of plant communities, generally leading to increased homogenization and decreased biodiversity. While many plant species have suffered from human activity, others have thrived due to their skill at colonizing habitats marked by anthropogenic activity. In …

The Incidence, Co-occurrence, and Predictors of Dysphagia, Dysarthria, and Aphasia after Acute Ischemic Stroke
… stroke. We sought to identify their frequency, co-occurrence, and predictors of them after acute ischemic stroke. Methods- First, we used the Registry of the Canadian Stroke Network’s (RCSN) database (2003–2008) from one stroke centre to identify a random sample of 250 patients with acute …

Incorporating plant community structure in species distribution modelling: a species co-occurrence based composite approach
… remotely sensed (RS) imagery is widely used in ecological studies and conservation planning, and the performance is frequently limited by factors including small plant size, small numbers of observations, and scattered distribution patterns. The focus of my thesis was to develop and evaluate …

Differentiating Types of Anxiety, Depression, and Their Co-Occurrence: Regional Brain Activity and Life Stress
… there has been a substantial amount of inconsistency across studies as to the specific regions implicated. This electroencephalographic study addressed two factors that might account for some of these discrepant findings. Hypotheses that patterns of regional brain activity would …

Co-occurrence of Oppositional Defiant Disorder with Generalized and Separation Anxiety Disorders Among Inner-city Children
There is a paucity of research that has examined co-occurring oppositional defiant disorder and generalized anxiety disorder (ODD+GAD) symptoms and oppositional defiant disorder and separation anxiety disorder (ODD+SAD) symptoms among children. To address this gap, I investigated multiple …

Temporal Patterns of Co-occurrence between Children's Self-regulatory Behaviour and their Private and Social Speech
… language has been identified as crucial in the cognitive development of young children, and has been observed on different time-scales. In particular, the real-time verbal mediation of behaviour has been studied in the context of private speech use and self-regulation, pioneered by Vygotsky and …

Composition, spatial abundance, co-occurrence and host preference of mistletoes in the Central highland savanna of Namibia
Aerial parasitic plants, commonly called mistletoes, are a polyphyletic group of organisms with a common evolutionary ancestor. This study was aimed at determining composition, spatial abundance within hosts, co-occurrence and host preference of mistletoes in the central highland savannas. The …

Characterizing A Novel Genetic Locus Associated With Familial Co-Occurrence of Thoracic Aortic Aneurysms and Intracranial Aneurysms
… 5p15 disease linked locus down to the genomic coordinates 5p15: 3,424,465- 6,312,925 (GRCh37/hg19 Assembly). This locus was named the TAA288 critical interval. Next, we sequenced candidate genes within the TAA288 critical interval. The selection of genes was simplified by the relatively small …

Assessment of co-occurrence of cyanotoxins, toxic metals and anionic surfactants in irrigation water, agricultural soils and food crops
Globally, the occurrence of cyanobacterial blooms in freshwater ecosystems has become a concern. Cyanobacteria produces secondary metabolites, known as cyanotoxins that cause acute and chronic poisoning in animals and humans. History of mining, industrial activities and poor maintenance of …
