What Research Should be Done and Why? Four Competing Visions among Ecologists

Information we collect about our planet depends, in part, on the questions scientists ask regarding the natural world. Asking other questions might lead to different innovations and alternative understandings of policy problems and their potential solutions. With a seemingly infinite number of potential study subjects but limited resources with which to study them, why have we chosen to focus on the topics that we have? Here, I present a Q-method study that explores ecologists\u27 thought processes as they evaluate the merits of potential research topics. The participants, ecologists attending the Ecological Society of America\u27s 2008 Annual Meeting, nominally agreed with one another that their discipline should contribute to solving environmental problems, but they interpreted that goal differently. This study uncovers four competing visions that ecologists have for their discipline. On the basis of these findings, I contend that ecology might be more effective in informing policy if priority setting were a more deliberative process and open to insights from individuals and institutions outside of ecology

Review of: Escape from the Ivory Tower: A Guide to Making Your Science Matter , by Nancy Baron

Collectively, ecologists produce a staggering amount of information each year. Using the Web of Science Journal Citation Reports subject classification to define the field of ecology, our discipline comprises 129 ecology-specific journals that in 2009 published an astounding 14 280 articles. How much of that information is being used by policymakers? How much is potentially useful to those audiences? The message in Nancy Baron’s new book, Escape from the ivory tower: a guide to making your science matter, is that all of it could be taken up by the media, publicized, and utilized by policymakers if only we could communicate it better to reporters and politicians. But communicating science and making it matter to the public or to policymakers are not the same thing, and the book falls short in addressing this latter point

Scientists, Managers, and Assisted Colonization: Four Contrasting Perspectives Entangle Science and Policy

Assisted colonization is a contentious climate change adaptation strategy, but we have limited understanding of the bases of disagreement amongst scientists and far less has been done to understand the views of other stakeholders. To establish an initial empirical understanding of the terms of the debate, we conducted a Q method study of the views of scientists and resource managers, a key constituency because of their role in decision-making and implementation. We asked 24 forest managers in Ontario, Canada and 26 top-publishing ecologists and conservation biologists to evaluate their level of agreement with 33 statements about assisted colonization from the published literature and other relevant sources. The analysis revealed four main, contrasting perspectives, which we label Ecological Interventionist, Nativist Technocrat, Interventionist Technocrat, and Reluctant Interventionist; all but the Nativist Technocrats were open to assisted colonization. Disagreements between the four perspectives were defined by value-based and policy-strategic considerations at least as much as they were by varied understandings of technical issues. Assisted colonization as a climate adaptation strategy exists within the context of multiple competing and incompatible problem definitions even amongst these technical stakeholders. Based upon our findings and the relevant literature, we conclude that disputes surrounding assisted colonization will likely not be settled by additional scientific research. Rather, underlying non-technical considerations need to be brought to the fore and addressed

Spanning Boundaries in an Arizona Watershed Partnership: Information Networks as Tools for Entrenchment or Ties for Collaboration?

The need to develop successful collaborative strategies is an enduring problem in sustainable resource management. Our goal is to evaluate the relationship between information networks and conflict in the context of collaborative groundwater management in the rapidly growing central highland region of Arizona. In this region, water-management conflicts have emerged because of stakeholders’ differing geographic perspectives and competing scientific claims. Using social network analyses, we explored the extent to which the Verde River Basin Partnership (VRBP), which was charged with developing and sharing scientific information, has contributed to collaboration in the region. To accomplish this, we examined the role that this stakeholder partnership plays in reinforcing or overcoming the geographic, ideological, expert, and power conflicts among its members. Focusing on information sharing, we tested the extent to which several theoretically important elements of successful collaboration were evidenced by data from the VRBP. The structure of information sharing provides insight into ways in which barriers between diverse perspectives might be retained and elucidates weaknesses in the partnership. To characterize information sharing, we examined interaction ties among individuals with different geographic concerns, hierarchical scales of interest, belief systems (about science, the environment, and the role of the partnership), and self-identified expertise types. Results showed that the partnership’s information-sharing network spans most of these boundaries. Based on current theories of collaboration, we would expect the partnership network to be conducive to collaboration. We found that information exchanges are limited by differences in connection patterns across actor expertise and environmental-belief systems. Actors who view scientists as advocates are significantly more likely to occupy boundary-spanning positions, that appear to impede the success of the partnership. This analysis challenges widely held assumptions about the properties that separate successful collaborations from those that are less successful. It has implications for our understanding of the factors that constrain information processing, knowledge production, and collective-action capability in institutions

The Star Formation Rate Function of the Local Universe

We have derived the bivariate luminosity function for the far ultraviolet (1530Angstroms) and far infrared (60 microns). We used matched GALEX and IRAS data, and redshifts from NED and PSC-z. We have derived a total star formation luminosity function phi(L_{tot}), with L_{tot} = L_{FUV}+L_{FIR}. Using these, we determined the cosmic ``star formation rate'' function and density for the local universe. The total SFR function is fit very well by a log-normal distribution over five decades of luminosity. We find that the bivariate luminosity function phi(L_{FUV},L_{FIR}) shows a bimodal behavior, with L_{FIR} tracking L_{FUV} for L_{TOT}< 10^10 L_sun, and L_{FUV} saturating at 10^10 L_sun, while L_{TOT} L_{FIR} for higher luminosities. We also calculate the SFR density and compare it to other measurements.Comment: This paper will be published as part of the Galaxy Evolution Explorer (GALEX) Astrophysical Journal Letters Special Issue.

Ego Network Properties as a Way to Reveal Conflict in Collaboration\u27s Clothing

A need for successful collaborative strategies is an enduring problem in natural resource management. Several qualities of “successful” partnerships have been identified but few empirical studies have tested these claims against the information sharing structure of “unsuccessful” partnerships. This paper examines the ego networks of members in a partnership that has not successfully reached its goals as an illustration of the ways in which external ties relate to attitudes and relationships within a partnership. By focusing on information sharing frequencies, member ideologies, and power structure among organizations involved in a groundwater controversy, we test the extent to which the process and outcomes of participation align with conditions often used to indicate “success”. Results show that individuals who think that science is objective maintain information sharing ego networks that include a larger proportion of ties outside of the partnership than those who consider science to be less certain. Individuals who consider themselves a member of the partnership are more central to the network of organizations invited to join the partnership and maintain a greater proportions of unique ties relative to ties common across multiple actors. This case study challenges widely held assumptions about the properties of successful collaborations and supports claims that scientific discourse can be used to obscure debates over values

GALEX UV Color Relations for Nearby Early-Type Galaxies

We use GALEX/optical photometry to construct color-color relationships for early-type galaxies sorted by morphological type. We have matched objects in the GALEX GR1 public release and the first IR1.1 internal release, with the RC3 early-type galaxies having a morphological type -5.5<T<-1.5 with mean error in T<1.5, and mean error on (B-V)T<0.05. After visual inspection of each match, we are left with 130 galaxies with a reliable GALEX pipeline photometry in the far-UV and near-UV bands. This sample is divided into Ellipticals (-5.5<T<-3.5) and Lenticulars (-3.5<T<-1.5). After correction for the Galactic extinction, the color-color diagrams FUV-NUV vs. (B-V)_{Tc} are plotted for the two subsamples. We find a tight anti-correlation between the FUV-NUV and (B-V)_{Tc} colors for Ellipticals, the UV color getting bluer when the (B-V)_{Tc} get redder. This relationship very likely is an extension of the color-metallicity relationship into the GALEX NUV band. We suspect that the main source of the correlation is metal line blanketing in the NUV band. The FUV-NUV vs B-V correlation has larger scatter for lenticular galaxies; we speculate this reflects the presence of low level star formation. If the latter objects (i.e. those that are blue both in FUV-NUV and B-V) are interpreted as harboring recent star formation activity, this would be the case for a few percent (~4%) of Ellipticals and ~15% of Lenticulars; this would make about 10% of early-type galaxies with residual star formation in our full sample of 130 early-type galaxies. We also plot FUV-NUV vs. the Mg_2 index and central velocity dispersion. We find a tight anti-correlation between FUV-NUV and the Mg_2 index(...).Comment: 25 pages, 5 figures, accepted for publication in ApJS (abstract abridged), typos corrected in section 2.

The Look-back Time Evolution of Far-Ultraviolet Flux from the Brightest Cluster Elliptical Galaxies at z < 0.2

We present the GALEX UV photometry of the elliptical galaxies in Abell clusters at moderate redshifts (z < 0.2) for the study of the look-back time evolution of the UV upturn phenomenon. The brightest elliptical galaxies (M_r < -22) in 12 remote clusters are compared with the nearby giant elliptical galaxies of comparable optical luminosity in the Fornax and Virgo clusters. The sample galaxies presented here appear to be quiescent without signs of massive star formation or strong nuclear activity, and show smooth, extended profiles in their UV images indicating that the far-UV (FUV) light is mostly produced by hot stars in the underlying old stellar population. Compared to their counterparts in nearby clusters, the FUV flux of cluster giant elliptical galaxies at moderate redshifts fades rapidly with ~ 2 Gyrs of look-back time, and the observed pace in FUV - V color evolution agrees reasonably well with the prediction from the population synthesis models where the dominant FUV source is hot horizontal-branch stars and their progeny. A similar amount of color spread (~ 1 mag) in FUV - V exists among the brightest cluster elliptical galaxies at z ~ 0.1, as observed among the nearby giant elliptical galaxies of comparable optical luminosity.Comment: Accepted for publication in the Special GALEX ApJ Supplement, December 200
