Hábitos de vida dos trilobitas das formações Maecuru e Ererê (Devoniano), Bacia do Amazonas
… These species were grouped into three morphotypes: morphotype I – Homalonotus derbyi – presents glabella, with shallow glabellar furrows, and glabellar frontal lobe weakly inflated; morphotype II – Phacopina brasiliensis, “Dalmanites” (gen. nov. aff. Fenestraspis) maecurua, “D.” (gen. …

Population structure and the molecular genetics of petal spot pigmentation in Gorteria diffusa
… is comprised of geographically discrete floral morphotypes, defined by extreme intraspecific variation in capitulum phenotype. Between-morphotype variation in the position and complexity of petal spots is associated with differential pollinator behavioural responses. As such, this system has …

Phenotypic diversity of indigenous rhizobia nodulating different morphotypes of Vachellia karroo
… thus enhance nitrogen fixation. Four different morphotypes of V. karroo obtained from four areas of South Africa with different agro-ecological conditions namely Kei Mouth, Richards Bay, Leeu Gamka and Tshwane were each grown in four soils, also obtained from these areas. Before planting the …

CBK Bacteriophage Genome Annotation and Organization
… three-fourths of these phages belonged to the B3 morphotype with phage CbK being the best studied. As no B3 phage genome sequences are currently available in the Genbank, we decided to determine the nucleotide sequence of the CBK genome. Bacteriophage CbK is a double-stranded DNA phage with an …

Germination hypogée et épigée chez le manioc. Adaptation à des milieux divergents ?
… à l'hypocotyle et aux cotylédons donnent des morphotypes divergents, et reflètent différentes stratégies de réponses à des perturbations extérieures. Notre étude portait sur une comparaison des comportements face à l'herbivorie, de jeunes plantules de deux espèces de manioc à morphotype …

Survival strategies of Mycobacterium avium subsp. paratuberculosis in a variety of microenvironments.
… We have identified the development of a new MAP morphotype under prolonged nutrient starved conditions. This novel MAP morphotype resembles a spore-like structure and contains dipicolinic acid, which is used to protect DNA located within the core. These novel structures are heat resistant at 70oC …

Antifungal Immune Responses and Inflammation in the Cystic Fibrosis Airways
… immune responses are fungus and fungal morphotype specific, and that the differences caused by the impaired function of the CFTR protein varies between host cell types. Aspergillus hyphae are more potent inducers of ROS than Aspergillus conidia, while Rasamsonia conidia are more potent …

Investigating Microbial Trace-fossils and Abiotic Alteration in Hydrovolcanic Tuffs of the Fort Rock Volcanic Field, Oregon
… in abiotic alteration and the abundance/morphotype assemblage of putative microborings between the sites indicate that water/rock ratio, fluid composition and flux, temperature and secondary phase formation are influences on microboring formation. This study is the first report of reputed …

Quantitative histopathology and epidemiology of prawn viral diseases
… i.e. the spheroid-total length ratio (STLR) and morphotype (MT) score. The results show that the ratio of spheroid length and morphotypes of the spheroids continually changed in a successive fashion from an early infection type (morphotype A) to a terminal type (morphotype C) in chronic or acute …

The effect of forest fertilization on the ectomycorrhizae of western hemlock (tsuga heterophylla)
… Melin, Thelephora terrestris Fr., 3 Russula morphotypes, 2 unidentified basidiomycetes and a morphotype which formed no mantle) were assessed using random soil cores taken at 0, 1, 3, 6, and 11months after fertilization. On both treated and control plots, total number of fine roots and number …

Exploring Microstructural Signatures of Physiological Stress through Cross-Sectional Geometry and Cortical Bone Histology
… annotate remodeling events (including osteon morphotype) and ImageJ was used to automate osteocyte lacunae counts, allowing for histomorphometrics osteon morphotype and osteocyte lacunae densities to be derived. Cross-sectional properties for each individual were also collected in ImageJ. …

New Zealand seagrass (Zostera muelleri) response to acute sedimentation: Linking non-structural carbohydrate reserves to resilience
… varied significantly between the three distinct morphotypes that existed in the three sites; a large, a small and an intermediate morphotype that overlapped with the small and the large morphotypes. These morphometric differences were believed to be phenotypic responses to site-specific …

Intertwined evolution of swimming, morphology and microhabitat in tree frogs from the subfamily Hylinae
… they jump, swim and climb. Convergences in morphotype and locomotion are primarily driven by microhabitat, but in some cases, morphology is the result of long-term phylogenetic constraints. Swimming is a critical behavior during life history for predator avoidance, reproduction, and early …

Population genetics of the genus Transennella (Bivalvia)
… The genus is characterized by two distinct morphotypes which differ in shell shape and pigmentation. Genetic similarity (I) and genetic distance (D) statistics were computed for the two morphotypes and for two populations of each morphotype. The I and D values derived from intraspecific …

Population structure of lake trout (Salvelinus namaycush) In Atlin Lake, British Columbia and contributions to local fisheries: a microsatellite DNA-based assessment
… lake identified to date to possess more than one morphotype. Genetic and morphological groupings were found not to be correlated with each other. Finally, I was interested in whether each of the genetic subpopulations contributed equally to the local fisheries catches. A mixed stock analysis of …

Assessing changes in pollen assemblage and charcoal accumulation during known changes in climate from c. 5,400 to 3,300 Years Before Present at the forest-prairie ecotone in Alberta, Canada
… accumulation rates for both total charcoal and morphotypes, as well as the percent relative abundance of charcoal morphotypes, were used to infer changes in landscape fire regimes during these aridity cycles. One-way ANOVAs were used to determine significant differences in average accumulation …

Isolation, identification, and in silico analysis of mycobacteriophage OKCentral2016.
… a morphology consistent with the Siphoviridae morphotype. The phage remained stable at temperatures below 55??C and under neutral pH conditions. The replication cycle took approximately 4 hours to complete under ideal growing conditions. I also examined the effect of OKCentral2016 on biofilms. …
