This article aims to provide an in-depth examination of the practices and perceptions of data management, including data storage, data sharing, and data use and reuse by scientists around the world. Methods The Usability and Assessment Working Group of DataONE, an NSF-funded environmental cyberinfrastructure project, distributed a survey to a multinational and multidisciplinary sample of scientific researchers in a two-waves approach in 2017–2018. We focused our analysis on examining the differences across age groups, sub-disciplines of science, and sectors of employment. Findings Most respondents displayed what we describe as high and mediocre risk data practices by storing their data on their personal computer, departmental servers or USB drives. Respondents appeared to be satisfied with short-term storage solutions; however, only half of them are satisfied with available mechanisms for storing data beyond the life of the process. Data sharing and data reuse were viewed positively: over 85% of respondents admitted they would be willing to share their data with others and said they would use data collected by others if it could be easily accessed. A vast majority of respondents felt that the lack of access to data generated by other researchers or institutions was a major impediment to progress in science at large, yet only about a half thought that it restricted their own ability to answer scientific questions. Although attitudes towards data sharing and data use and reuse are mostly positive, practice does not always support data storage, sharing, and future reuse. Assistance through data managers or data librarians, readily available data repositories for both long-term and short-term storage, and educational programs for both awareness and to help engender good data practices are clearly needed.}, number={3}, journal={PLOS ONE}, author={Tenopir, Carol and Rice, Natalie M. and Allard, Suzie and Baird, Lynn and Borycz, Josh and Christian, Lisa and Grant, Bruce and Olendorf, Robert and Sandusky, Robert J.}, year={2020}, month={Mar} }

Part 1 describes basic concepts in graph theory and how graph theory has been applied by information retrieval systems such as Google. Part 2 discusses practical applications of graph theory in digital library environments. Some of the applications have been prototyped at the Los Alamos National Laboratory Research Library, others have been described in peer-reviewed journals, and still others are speculative in nature.

Principal components analysis (PCA) of four component variables of nest defence (call rate, swoop rate, closest approach and number of adults) generated a measure of overall nest defence (aggression). We determined effectiveness of defence by looking for correlations between measures of defence and measures of nest success (nest predation and brood parasitism). We also determined whether nest defence increased with clutch size, nestling age and time in the breeding season. Defence against model Brown‐headed Cowbirds did not correlate with levels of parasitism, clutch size, age of young or time of breeding. There was, however, a strong, but insignificant, trend for nests with high levels of all measures of defence to suffer less from brood parasitism. Aggression, vocalization rate, closest approach and number of adults defending against models of predatory Blue Jays correlated positively with nesting success during the egg stage but not the nestling stage of the nesting cycle. Aggression, vocalization rate, closest approach correlated with clutch size and age of the brood. These results suggest that nest defence can effectively deter nest predators, but may be less effective against brood parasites. Different behavioural components of nest defence may work at different stages of the nest cycle and against different nest predators. The components of nest defence that correlated with nest success also correlated with clutch value, a result consistent with hypotheses on the evolution of nest defence.}, number={3}, journal={Ibis}, publisher={Wiley Blackwell (Blackwell Publishing)}, author={OLENDORF, ROBERT and ROBINSON, SCOTT K.}, year={2008}, pages={365–371} }

Of the processes capable of maintaining variation, negative frequency-dependent selection (where rare types are favoured by selection) is the most powerful, at least in theory; however, few experimental studies have confirmed that this process operates in nature. One of the most extreme, unexplained genetic polymorphisms is seen in the colour patterns of male guppies (Poecilia reticulata). Here we manipulated the frequencies of males with different colour patterns in three natural populations to estimate survival rates, and found that rare phenotypes had a highly significant survival advantage compared to common phenotypes. Evidence from humans and other species implicates frequency-dependent survival in the maintenance of molecular, morphological and health-related polymorphisms. As a controlled manipulation in nature, this study provides unequivocal support for frequency-dependent survival--an evolutionary process capable of maintaining extreme polymorphism.}, number={7093}, journal={Nature}, author={Olendorf, R. and Rodd, F.H. and Punzalan, D. and Houde, A.E. and Hurt, C. and Reznick, D.N. and Hughes, K.A.}, year={2006}, pages={633–636} }

Some studies have suggested that this is an example of by–product mutualism, whereas others have suggested the possibility of reciprocal altruism. No study has addressed the possibility of kin–selected cooperation in nest defence in this species. Reciprocal altruism, kin selection and by–product mutualism are not mutually exclusive alternatives, but few studies of territorial neighbours have tested for multiple mechanisms simultaneously. We test for these three possibilities in a population of red–winged blackbirds. We used simulated defections to test for reciprocal altruism. We used analysis of microsatellite loci to test for kin selection between adult male neighbours. We also used microsatellite loci to test for by–product mutualism resulting from nest defence of offspring sired on neighbouring territories. We found that male red–winged blackbirds cooperate in nest defence primarily as a form of reciprocal altruism. Experimental males reduced their level of nest defence relative to controls following simulated defection by a neighbour. In contrast to some earlier studies, we found no evidence for by–product mutualism: males did not defend nests where they had sired extra–pair offspring. We also found no evidence for kin selection: males were no more cooperative with more closely related neighbours. Considered alongside the results from other studies, our study suggests that mechanisms stabilizing cooperation in red–winged blackbirds may vary among populations.}, number={1535}, journal={Proceedings of the Royal Society B: Biological Sciences}, publisher={The Royal Society}, author={Olendorf, R. and Getty, T. and Scribner, K.}, year={2004}, pages={177–182} }

We present evidence that among male red–winged blackbirds (Agelaius phoeniceus) the dear–enemy relationship is a form of reciprocal conditional cooperation that is stabilized, at least in part, by retaliation against cheaters. Simulated intrusions by randomly chosen neighbours were punished by a targeted increase in vigilance and aggression that persists for days. We interpret this increase in vigilance towards trespassers as a manifestation of distrust. The conditional decrease in vigilance and aggression is tempered by each neighbour's probability of cuckolding the focal male. Male red–winged blackbirds maintained greater vigilance and aggression towards sexually attractive neighbours that were more successful at extra–pair fertilizations (EPFs). It is unlikely that males directly observed neighbours copulating with their mates. They were more likely to assess a neighbour's ability to achieve extra–pair copulations using surrogate cues that correlate with success at EPFs, including body size. Our results suggest that red–winged blackbirds use rules that incorporate their neighbour's behaviour and quality in their territorial interactions with one another. Our results expand our understanding of cooperation for animals and for humans as well.}, number={1543}, journal={Proceedings of the Royal Society B: Biological Sciences}, publisher={The Royal Society}, author={Olendorf, R. and Getty, T. and Scribner, K. and Robinson, S.
