TL;DR: GFP can be used as a tool to monitor transgene flow from crop species to wild relatives and was macroscopically detectable throughout the entire life cycle of canola.
Abstract: It is possible to monitor the movement of transgenes by tagging them with green fluorescent pro- tein (GFP). In order to develop a model to study trans- gene flow, canola (Brassica napus cv Westar) was trans- formed with two GFP constructs, mGFP5er (GFP only) and pSAM 12 (GFP linked to a synthetic Bacillus thuringiensis (Bt) cry1Ac endotoxin gene). Transformed callus sectors that fluoresced green were preferentially selected in the tissue culture process. Four independent GFP canola events and 12 events of GFP/Bt canola were regenerated through tissue culture. GFP fluorescence was macroscopically detectable throughout the entire life cycle of canola. The GFP/Bt events were insecticidal to neonate corn earworm (Helicoverpa zea) larvae and prevented herbivory damage. Fluorescence intensity at 508 nm varied between the independent transformation events, and ranged from 7.6× 10 5 to 13.8× 10 5 (counts per second) in contrast with the wild-type at 5.3 × 105 cps. Nine GFP/Bt and three GFP events were hybridized with three wild accessions of B. rapa. The resultant hybrids fluoresced green and were insecticidal to neonate corn earworm larvae to the same degree as the transgenic ca- nola parents. However, fluorescence intensities of the hemizygous F 1 hybrid lines were lower than the respec- tive original homozygous canola parents. Each F 1 hybrid line was backcrossed by hand onto the B. rapa parent, and transgenic backcrosses were produced at rates rang- ing from 15% to 34%. These data suggest that GFP can be used as a tool to monitor transgene flow from crop species to wild relatives.

TL;DR: The authors explored the identity re-creation process as it occurs via the consumption of Internet dating services and found that online and offline validation of the identities presented in dating profiles seem to have an impact on individuals' beliefs about themselves and their behavior in both online and off-line environments.
Abstract: This research explored the identity re-creation process as it occurs via the consumption of Internet dating services. Informants were interviewed about how they use their posted dating profiles to explore aspects of their own identities and about the perceived impact that online and offline feedback to these profiles have upon their identities. Informants' responses indicated that individuals can re-create their identities through the use of Internet dating services. Furthermore, online and offline validation of the identities presented in dating profiles seem to have an impact on individuals' beliefs about themselves and their behavior in both online and offline environments.

TL;DR: It was revealed that family recreation most often involved small combinations of family members - usually mothers and their children - in physical recreation activities (e.g. swimming, walking, bike riding) which parents viewed as beneficial for enhancing family relationships and providing children, particularly those with a disability, opportunities for skill and self development within an accepting and supportive environment.
Abstract: Grounded in the naturalistic paradigm, a mixed-method research design (survey questionnaire, n = 65; and interview, n = 16) was used to explore the nature and benefits of, and constraints to, family
recreation in families that included children with developmental disability. Statistical analyses were conducted on the quantitative data, while key theme and constant comparative methods were used to analyse the qualitative data.

TL;DR: Results suggest that inflexibility in certain areas of the musculoskeletal system may enhance running economy in sub-elite male runners by increasing storage and return of elastic energy and minimizing the need for muscle-stabilizing activity.
Abstract: The purpose of this study was to examine the association between nine measures of limb and trunk flexibility and running economy. Within a week prior to running economy assessment, and after 10 min of jogging at 3.13 m.s-1, 19 well-trained male sub-elite distance runners underwent two complete sets of lower limb and trunk flexibility assessments. Runners then completed two 10-min running economy assessment sessions on consecutive days at 4.13 m.s-1 following two 30-min sessions of treadmill accommodation at 4.13 m.s-1. Intraclass correlation coefficients indicated that the repeated flexibility measurements were highly reliable (X R = 0.92 +/- 0.09), as were the two running economy appraisals (R = 0.99). Correlational analyses revealed that dorsiflexion (r = 0.65) and standing hip rotation (r = 0.53) were significantly (P < or = 0.05) associated with the mean aerobic demand of running, such that runners who were less flexible on these measures were more economical. Although speculative, these results suggest that inflexibility in certain areas of the musculoskeletal system may enhance running economy in sub-elite male runners by increasing storage and return of elastic energy and minimizing the need for muscle-stabilizing activity.

TL;DR: In the early part of the 20th century, population thinking overtook the field of systematics, and the subsequent growth of the entire field of population biology as discussed by the authors, leading to a new field of phylogenetic biology.
Abstract: Two new modes of thinking have spread through systematics in the twentieth century. Both have deep historical roots, but they have been widely accepted only during this century. Population thinking overtook the field in the early part of the century, culminating in the full development of population systematics in the 1930s and 1940s, and the subsequent growth of the entire field of population biology. Population thinking rejects the idea that each species has a natural type (as the earlier essentialist view had assumed), and instead sees every species as a varying population of interbreeding individuals. Tree thinking has spread through the field since the 1960s with the development of phylogenetic systematics. Tree thinking recognizes that species are not independent replicates within a class (as earlier group thinkers had tended to see them), but are instead inter-connected parts of an evolutionary tree. It lays emphasis on the explanation of evolutionary events in the context of a tree, rather than on the states exhibited by collections of species, and it sees evolutionary history as a story of divergence rather than a story of development. Just as population thinking gave rise to the new field of population biology, so tree thinking is giving rise to the new field of phylogenetic biology.
