AbstractThe EU Water Framework Directive requires the development of management responses aimed towards improving water quality as a result of improving ecosystem health (system state). Ecosystems have potential to supply a range of services that are of fundamental importance to human well-being, health, livelihoods and survival, and their capacity to supply these services depends on the ecosystem condition (its structure and processes). According to the WFD, Programmes of Measures should be developed to improve overall water status by reducing anthropogenic catchment pressures to levels compatible with the achievement of the ecological objectives of the directive, and when designed and implemented properly should improve the ecological condition of aquatic ecosystems that the delivery of ecosystem services depends on. Monitoring and evaluation of implemented measures are crucial for assessing their effectiveness and creating the agenda for consecutive planning cycles. Considering the challenges of achieving water status improvements, and the difficulties of communicating these to the wider public, we develop a framework for the evaluation of measures cost-effectiveness that considers ecosystem services as the benefits from the reduction of pressures on water bodies. We demonstrate its application through a case study and discuss its potential to facilitate the economic analysis required by the directive, and that most European water authorities had problems with. Findings demonstrate the potential of the methodology to effectively incorporate ecosystem services in the assessment of costs and benefits of proposed actions, as well as its potential to engage stakeholders.

Developing a general, predictive understanding of ecological systems requires knowing how much structural and functional relationships can cross scales and contexts. Here, we introduce the CROSSLINK project that investigates the role of forested riparian buffers in modified European landscapes by measuring a wide range of ecosystem attributes in stream-riparian networks. CROSSLINK involves replicated field measurements in four case-study basins with varying levels of human development: Norway (Oslo Fjord), Sweden (Lake Mälaren), Belgium (Zwalm River), and Romania (Argeş River). Nested within these case-study basins include multiple, independent stream-site pairs with a forested riparian buffer and unbuffered section located upstream, as well as headwater and downstream sites to show cumulative land-use impacts. CROSSLINK applies existing and bespoke methods to describe habitat conditions, biodiversity, and ecosystem functioning in aquatic and terrestrial habitats. Here, we summarize the approaches used, detail protocols in supplementary materials, and explain how data is applied in an optimization framework to better manage tradeoffs in multifunctional landscapes. We then present results demonstrating the range of riparian conditions present in our case-study basins and how these environmental states influence stream ecological integrity with the commonly used macroinvertebrate Average Score Per Taxon (ASPT) index. We demonstrate that a qualitative index of riparian integrity can be positively associated with stream ecological status. This introduction to the CROSSLINK project shows the potential for our replicated study with its panoply of ecosystem attributes to help guide management decisions regarding the use of forested riparian buffers in human-impacted landscapes. This knowledge is highly relevant in a time of rapid environmental change where freshwater biodiversity is increasingly under pressure from a range of human impacts that include habitat loss, pollution, and climate change.

Purpose The purpose of this paper is to present a case study of how ecological considerations can be integrated into campus strategic and statutory spatial planning. A process of developing ecological objectives and guidelines for inclusion in campus strategic and statutory spatial plans is presented. Design/methodology/approach This case study introduces a three-phase ecological assessment process developed and applied to the Technion – IIT campus. Ecological considerations are reviewed in multiple campus strategic and spatial plans (primarily in North America and Europe) and in institutional sustainability guidelines; biodiversity and ecosystem service surveys of the campus are conducted and considered with regard to planning; university administrative structures that enable the implementation of ecological planning guidelines are also assessed. Findings Ecological considerations (biodiversity conservation, habitat preservation and ecosystem integrity) play a relatively minor role in sustainability planning on university campuses. The concepts of connectivity and compactness are applied broadly, but generally refer to social and educational considerations. Physical planning provides an opportunity for integrating ecological priorities into the university’s mission. Research limitations/implications Some of the insights may not be generalizable, so it is crucial to continue accumulating similar studies. It is crucial, too, to conduct follow-up research, reporting on the ecological outcomes of plan implementation. Practical implications Ecological stewardship is commensurate with the sustainability commitments of universities. Considering their spatial extent and diverse locations, universities can assume an important role in ecological conservation. Originality/value Relatively little attention has been given to ecological considerations (biodiversity, ecological integrity and ecosystem services) in campus plans and sustainability documents. This paper suggests how universities can move towards fulfilling a role as ecological stewards through strategic and spatial planning.

To solve transferability and spatial-temporal variability problems of ecological flow (EF) criteria existed in traditional Tennant methods, a new modified Tennant method was proposed. Considering the temporal variability and influence of extreme flows on average annual flow, the EF criteria for every month and water year were set as variables, and median monthly flow was taken as the optimum EF ceiling. Considering transferability and spatial variation of ecological objectives in different water function zones, the mean of monthly flow under 95% guaranteed rate and minimum monthly flow was used as the minimum EF. To avoid arbitrary use of EF criteria at all levels, the idea of arithmetic progression was introduced. On achieving satisfactory verification, the new approach was applied in the Hanjiang River as a case study. It is found that this new approach is reasonable with excellent spatial-temporal variability.

AbstractUsing interviews with former militants and previously unpublished documents, this article traces the genesis and internal dynamics of the Ejército Revolucionario del Pueblo (People's Revolutionary Army, ERP) in El Salvador during the early years of its existence (1970–6). This period was marked by the inability of the ERP to maintain internal coherence or any consensus on revolutionary strategy, which led to a series of splits and internal fights over control of the organisation. The evidence marshalled in this case study sheds new light on the origins of the armed Salvadorean Left and thus contributes to a wider understanding of the processes of formation and internal dynamics of armed left-wing groups that emerged from the 1960s onwards in Latin America.

Abstract Culture shapes our basic sensory experience of the world. This is particularly striking in the study of religion and psychosis, where we and others have shown that cultural context determines both the structure and content of hallucination-like events. The cultural shaping of hallucinations may provide a rich case-study for linking cultural learning with emerging prediction-based models of perception.

Abstract Hoerl and McCormack demonstrate that although animals possess a sophisticated temporal updating system, there is no evidence that they also possess a temporal reasoning system. This important case study is directly related to the broader claim that although animals are manifestly capable of first-order (perceptually-based) relational reasoning, they lack the capacity for higher-order, role-based relational reasoning. We argue this distinction applies to all domains of cognition.

Abstract Sociocultural developmental psychology can drive new directions in gadgetry science. We use autobiographical memory, a compound capacity incorporating episodic memory, as a case study. Autobiographical memory emerges late in development, supported by interactions with parents. Intervention research highlights the causal influence of these interactions, whereas cross-cultural research demonstrates culturally determined diversity. Different patterns of inheritance are discussed.
