Twenty-three unsolved problems in hydrology (UPH) – a community perspective

This paper is the outcome of a community initiative to identify major unsolved scientific problems in hydrology motivated by a need for stronger harmonisation of research efforts. The procedure involved a public consultation through on-line media, followed by two workshops through which a large number of potential science questions were collated, prioritised, and synthesised. In spite of the diversity of the participants (230 scientists in total), the process revealed much about community priorities and the state of our science: a preference for continuity in research questions rather than radical departures or redirections from past and current work. Questions remain focussed on process-based understanding of hydrological variability and causality at all space and time scales. Increased attention to environmental change drives a new emphasis on understanding how change propagates across interfaces within the hydrological system and across disciplinary boundaries. In particular, the expansion of the human footprint raises a new set of questions related to human interactions with nature and water cycle feedbacks in the context of complex water management problems. We hope that this reflection and synthesis of the 23 unsolved problems in hydrology will help guide research efforts for some years to come

Plant trait composition as an indicator for the ecological memory of rehabilitated floodplains

Maintaining ecosystem functioning under global change requires resilient ecosystems to absorb disturbances, reorganize and maintain the adaptive capacity. Maintaining resilience is therefore a common objective for ecosystem management, but how this objective may be achieved remains largely unclear. The concept of ecological memory provides a perspective on how the adaptive capacity of ecosystems can be enhanced through management. It specifies how ecological processes in space and time assist in the reorganization of communities after disturbances. We present a trait-based approach that links environmental variables at site and patch level to plant traits. With a generalized linear mixed-effects model we test how environmental variation in management and floodplain dynamics, within and between sites, relates to plant traits that are considered relevant for ecological memory. The results show different mechanisms that intervene in ecological memory. Grazing enhances recruitment opportunities, both for internal reorganization and for colonization between sites. Dense vegetation structure selects for species survival via resprouting after disturbance and competitive species. Hydrodynamics interact with seed dispersal mechanisms and seed persistence. We show that at different spatial levels, plant trait composition can act as an indicator of ecological processes contributing to the ecological memory of a floodplain ecosystem. For ecosystem management to maintain and use as much of this memory as possible it should incorporate management measures at various levels of scale to enhance ecosystem resilience.</p

Research, Ethics and Risk in the Authoritarian Field

This open access book offers a synthetic reflection on the authors’ fieldwork experiences in seven countries within the framework of ‘Authoritarianism in a Global Age’, a major comparative research project. It responds to the demand for increased attention to methodological rigor and transparency in qualitative research, and seeks to advance and practically support field research in authoritarian contexts. Without reducing the conundrums of authoritarian field research to a simple how-to guide, the book systematically reflects and reports on the authors’ combined experiences in (i) getting access to the field, (ii) assessing risk, (iii) navigating ‘red lines’, (iv) building relations with local collaborators and respondents, (v) handling the psychological pressures on field researchers, and (vi) balancing transparency and prudence in publishing research. It offers unique insights into this particularly challenging area of field research, makes explicit how the authors handled methodological challenges and ethical dilemmas, and offers recommendations where appropriate

Genetic contribution to renal function and electrolyte balance: a twin study

A classical twin study was performed to assess the relative contributions of genetic and environmental factors to serum levels of calcium, phosphate and magnesium, urinary levels of calcium, sodium and potassium, and creatinine clearance. The subjects were 1747 adult female twin pairs: 539 monozygotic and 1208 dizygotic. The intraclass correlations were calculated, and maximum-likelihood model fitting was used to estimate genetic and environmental variance components. The intraclass correlations for all of the variables assessed were higher in monozygotic twin pairs. The heritabilities (with 95% confidence intervals) obtained from model fitting were: serum calcium, 33% (21-45%); serum phosphate, 58% (53-62%), serum magnesium, 27% (15-39%); 24 h urinary potassium, 40% (27-51%); 24 h urinary calcium, 52% (41-61%); 24 h urinary sodium, 43% (30-54%); fractional excretion of sodium, 52% (44-59%); serum creatinine, 37% (25-49); calculated creatinine clearance, 63% (54-72%). This study provides evidence for the importance of genetic factors in determining urinary and blood levels of the major electrolytes involved in blood pressure regulation. Identifying heritability is the first step on the way to finding specific genes, which may improve our insight into the pathophysiology of the metabolism of these electrolytes, and thereby improve our understanding of the aetiology of complex diseases such as renal failure and hypertension
