More Than a Service: Values of Rivers, Wetlands and Floodplains Are Informed by Both Function and Feeling.

How people value rivers, wetlands and floodplains influences their attitudes, beliefs and behaviours towards these ecosystems, and can shape policy and management interventions. Better understanding why people value rivers, wetlands and floodplains and their key ecosystem components, such as vegetation, helps to determine what factors underpin the social legitimacy required for effective management of these systems. This study sought to ascertain perspectives on the value of non-woody vegetation in river-floodplain systems via an online survey. The survey found that participants valued non-woody vegetation for their provision of a range of ecosystem functions and services, with strong emphasis on ecological aspects such as regulation functions, habitat provision and biodiversity. However, the inclusion of a question framed to focus on stories or narratives resulted in a different emphasis. Responses indicated that non-woody vegetation, and rivers, wetlands and floodplains were valued for the way they made people feel through lived experiences such as recreational activities, personal interactions with nature, educational and research experiences. This highlights the important role of storytelling in navigating complex natural resource management challenges and ascertaining a deeper understanding of values that moves beyond provision of function to feeling. Improved understanding of the diverse ways people value and interact with river-floodplain systems will help develop narratives and forms of engagement that foster shared understanding, empathy and collaboration. Appreciation of plural values such as the provision of functions and services along with the role of emotional connections and lived experience will likely increase lasting engagement of the general public with management to protect and restore river-floodplain systems.

Beyond a 'just add water' perspective: environmental water management for vegetation outcomes.

Practitioners of environmental water management (EWM) operate within complex social-ecological systems. We sought to better understand this complexity by investigating the management of environmental water for vegetation outcomes. We conducted an online survey to determine practitioners' perspectives on EWM for non-woody vegetation (NWV) in the Murray-Darling Basin, Australia with regards to: i) desirable outcomes and benefits; ii) influencing factors and risks; iii) challenges of monitoring and evaluation, and iv) improving outcomes. Survey participants indicated that EWM aims to achieve outcomes by improving or maintaining vegetation attributes and the functions and values these provide. Our study reveals that EWM practitioners perceive NWV management in a holistic and highly interconnected way. Numerous influencing factors as well as risks and challenges to achieving outcomes were identified by participants, including many unrelated to water. Survey responses highlighted six areas to improve EWM for NWV outcomes: (1) flow regimes, (2) vegetation attributes, (3) non-flow drivers, (4) management-governance considerations, (5) functions and values, and (6) monitoring, evaluation and research. These suggest a need for more than 'just water' when it comes to the restoration and management of NWV. Our findings indicate more integrated land-water governance and management is urgently required to address the impacts of non-flow drivers such as pest species, land-use change and climate change. The results also indicate that inherent complexity in EWM for ecological outcomes has been poorly addressed, with a need to tackle social-ecological constraints to improve EWM outcomes.

Acute, diel, and annual temperature variability and the thermal biology of ectotherms.

Global warming is increasing mean temperatures and altering temperature variability at multiple temporal scales. To better understand the consequences of changes in thermal variability for ectotherms it is necessary to consider thermal variation at different time scales (i.e., acute, diel, and annual) and the responses of organisms within and across generations. Thermodynamics constrain acute responses to temperature, but within these constraints and over longer time periods, organisms have the scope to adaptively acclimate or evolve. Yet, hypotheses and predictions about responses to future warming tend not to explicitly consider the temporal scale at which temperature varies. Here, focusing on multicellular ectothermic animals, we argue that consideration of multiple processes and constraints associated with various timescales is necessary to better understand how altered thermal variability because of climate change will affect ectotherms.

Taking perspective on attachment theory and research: nine fundamental questions.

Since its inception more than 50 years ago, attachment theory has become one of the most influential viewpoints in the behavioral sciences. What have we learned during this period about its fundamental questions? In this paper, we summarize the conclusions of an inquiry into this question involving more than 75 researchers. Each responded to one of nine "fundamental questions" in attachment theory. The questions concerned what constitutes an attachment relationship, how to measure the security of attachment, the nature and functioning of internal working models, stability and change in attachment security, the legacy of early attachment relationships, attachment and culture, responses to separation and loss, how attachment-based interventions work, and how attachment theory informs systems and services for children and families. Their responses revealed important areas of theoretical consensus but also surprising diversity on key questions, and significant areas of remaining inquiry. We discuss central challenges for the future.

Parents' attachment orientation, interviewers' support, and children's memory for a mildly distressing event.

Parents' attachment orientations predict children's memory about distressing life events, such that parents who are less secure in close relationships tend to have children who are less accurate in their memory reports. This study examined whether socially supportive interviewing would reduce differences in children's memory performance associated with parents' attachment. Children (3 to 5 years, N = 63) and their primary caretakers took part in the Preschool Attachment Classification System (PACS), a moderately distressing event for children of preschool age that is based on the Strange Situation Procedure. Children's memory for the event was then tested shortly thereafter by either a supportive or a non-supportive interviewer. In the non-supportive condition, children whose parents scored higher on attachment avoidance provided lower proportions of correct free recall. However, the association was not significant for children in the supportive condition. In addition, higher parental attachment anxiety predicted lower proportions of correct free recall for children of highly avoidant parents, but not for children of parents lower in attachment avoidance. For direct questions, age differences in proportion correct and proportion incorrect favoured older children. Findings provide insight into interviewing techniques at time of memory retrieval that benefit children of insecure parents.

Eyes to see and ears to hear: sensitivity in research on attachment and culture.

How and why should attachment researchers engage in research on attachment and culture? How should they strive to develop a theoretical perspective that is both contextually sensitive and also reflecting species-typical processes of evolutionary adaptation? These comments on the remarkable empirical papers of this special issue consider what is learned from these studies, what more is needed, and directions for future research.

Attachment networks and the future of attachment theory.

Attachment theorists have long recognized that multiple attachments characterize the typical experience of most children. But an appreciation of attachment networks is new, and this commentary draws on some of the most theoretically provocative themes of the contributions to this special issue. These include: how the quality of attachment relationships and the contexts of their development colors the security derived from them and the developmental outcomes they influence; the impact of relationships on other relationships in the attachment network; and the multiple ways attachment theory can influence public policy for children and families.

On what is read, shared, and felt: parent-child conversation about stories.

Picture book reading is a forum for early language development and for the development of relationships, as reading a story evokes connections between the narrative, the reader, and the child, and invites shared understanding of the story as it intersects with the child's experience. The study by Teufl and colleagues poses interesting questions about the nature and influence of parent-child discourse around picture books and how it changes developmentally. It also raises provocative questions about how we assess the relative influence of maternal and paternal attachment relationships. These issues are the focus of this commentary.

Cooperation and obligation in early parent-child relationships.

Tomasello's moral psychology of obligation would be developmentally deepened by greater attention to early experiences of cooperation and shared social agency between parents and infants, evolved to promote infant survival. They provide a foundation for developing understanding of the mutual obligations of close relationships that contribute (alongside peer experiences) to growing collaborative skills, fairness expectations, and fidelity to social norms.

Emotion dysregulation: A theme in search of definition.

Emotion dysregulation is defined as patterns of emotional experience or expression that interfere with goal-directed activity. This paper considers this functionalist definition from a developmental perspective with the goal of elaborating this approach with respect to its central questions. What are the goals that are impeded by emotionally dysregulated responding, and what alternative goals might motivate emotion dysregulation? What are the developmental processes by which these goals take shape, and what are the influences of the family context, and especially of central relationships in the family, in their emergence? How does this functionalist account address the complex interaction of experience and developing biological processes that also influence emotion regulation and dysregulation? Drawing on research literature concerning children at risk for affective psychopathology and considering relevant examples of the interaction of biology and context, this discussion offers a portrayal of emotion dysregulation as a biologically dynamic, experience-based aspect of adaptation to environments and relationships that, in conditions of risk for the emergence of developmental psychopathology, motivates patterns of emotional responding that serve immediate coping often at the cost of long-term maladaptation. Implications for emotions theory and the study of developmental psychopathology are also considered.

Karyotypes and Sex Chromosomes in Two Australian Native Freshwater Fishes, Golden Perch (Macquaria ambigua) and Murray Cod (Maccullochella peelii) (Percichthyidae).

Karyotypic data from Australian native freshwater fishes are scarce, having been described from relatively few species. Golden perch (Macquaria ambigua) and Murray cod (Maccullochella peelii) are two large-bodied freshwater fish species native to Australia with significant indigenous, cultural, recreational and commercial value. The arid landscape over much of these fishes' range, coupled with the boom and bust hydrology of their habitat, means that these species have potential to provide useful evolutionary insights, such as karyotypes and sex chromosome evolution in vertebrates. Here we applied standard and molecular cytogenetic techniques to characterise karyotypes for golden perch and Murray cod. Both species have a diploid chromosome number 2n = 48 and a male heterogametic sex chromosome system (XX/XY). While the karyotype of golden perch is composed exclusively of acrocentric chromosomes, the karyotype of Murray cod consists of two submetacentric and 46 subtelocentric/acrocentric chromosomes. We have identified variable accumulation of repetitive sequences (AAT)10 and (CGG)10 along with diverse methylation patterns, especially on the sex chromosomes in both species. Our study provides a baseline for future cytogenetic analyses of other Australian freshwater fishes, especially species from the family Percichthyidae, to better understand their genome and sex chromosome evolution.

How children remember the Strange Situation: The role of attachment.

This study tested predictions from Bowlby's attachment theory about children's memory and suggestibility. Young children (3-5years old, N=88; 76% Caucasians) and their parents took part in the Strange Situation Procedure, a moderately distressing event and "gold standard" for assessing children's attachment quality. The children were then interviewed about what occurred during the event. Children's age and attachment security scores positively predicted correct information in free recall and accuracy in answering specific questions. For children with higher (vs. lower) attachment security scores, greater distress observed during the Strange Situation Procedure predicted increased resistance to misleading suggestions. In addition, for children who displayed relatively low distress during the Strange Situation Procedure, significant age differences in memory and suggestibility emerged as expected. However, for children who displayed greater distress during the Strange Situation Procedure, younger and older children's memory performances were equivalent. Findings suggest that attachment theory provides an important framework for understanding facets of memory development with respect to attachment-related information and that distress may alter assumed age patterns in memory development.

CDC Grand Rounds: Addressing Health Disparities in Early Childhood.

Research suggests that many disparities in overall health and well-being are rooted in early childhood (1,2). Stressors in early childhood can disrupt neurologic, metabolic, and immunologic systems, leading to poorer developmental outcomes (1). However, consistent, responsive caregiving relationships and supportive community and health care environments promote an optimal trajectory (3,4). The first 8 years of a child's life build a foundation for future health and life success (5-7). Thus, the cumulative and lifelong impact of early experiences, both positive and negative, on a child's development can be profound. Although the health, social service, and education systems that serve young children and their families and communities provide opportunities to support responsive relationships and environments, efforts by these systems are often fragmented because of restrictions that limit the age groups they can serve and types of services they can provide. Integrating relationship-based prevention and intervention services for children early in life, when the brain is developing most rapidly, can optimize developmental trajectories (4,7). By promoting collaboration and data-driven intervention activities, public health can play a critical role in both the identification of at-risk children and the integration of systems that can support healthy development. These efforts can address disparities by reducing barriers that might prevent children from reaching their full potential.

Rapid divergence of animal personality and syndrome structure across an arid-aquatic habitat matrix.

Intraspecific trait variation, including animal personalities and behavioural syndromes, affects how individual animals and populations interact with their environment. Within-species behavioural variation is widespread across animal taxa, which has substantial and unexplored implications for the ecological and evolutionary processes of animals. Accordingly, we sought to investigate individual behavioural characteristics in several populations of a desert-dwelling fish, the Australian desert goby (Chlamydogobius eremius). We reared first generation offspring in a common garden to compare non-ontogenic divergence in behavioural phenotypes between genetically interconnected populations from contrasting habitats (isolated groundwater springs versus hydrologically variable river waterholes). Despite the genetic connectedness of populations, fish had divergent bold-exploratory traits associated with their source habitat. This demonstrates divergence in risk-taking traits as a rapid phenotypic response to ecological pressures in arid aquatic habitats: neophilia may be suppressed by increased predation pressure and elevated by high intraspecific competition. Correlations between personality traits also differed between spring and river fish. River populations showed correlations between dispersal and novel environment behaviours, revealing an adaptive behavioural syndrome (related to dispersal and exploration) that was not found in spring populations. This illustrates the adaptive significance of heritable behavioural variation within and between populations, and their importance to animals persisting across contrasting habitats.

A framework for evaluating food-web responses to hydrological manipulations in riverine systems.

Environmental flows are used to restore elements of the hydrological regime altered by human use of water. One of the primary justifications and purposes for environmental flows is the maintenance of target species populations but, paradoxically, there has been little emphasis on incorporating the food-web and trophic dynamics that determine population-level responses into the monitoring and evaluation of environmental flow programs. We develop a generic framework for incorporating trophic dynamics into monitoring programs to identify the food-web linkages between hydrological regimes and population-level objectives of environmental flows. These linkages form the basis for objective setting, ecological targets and indicator selection that are necessary for planning monitoring programs with a rigorous scientific basis. Because there are multiple facets of trophic dynamics that influence energy production and transfer through food webs, the specific objectives of environmental flows need to be defined during the development of monitoring programs. A multitude of analytical methods exist that each quantify distinct aspects of food webs (e.g. energy production, prey selection, energy assimilation), but no single method can provide a basis for holistic understanding of food webs. Our paper critiques a range of analytical methods for quantifying attributes of food webs to inform the setting, monitoring and evaluation of trophic outcomes of environmental flows and advance the conceptual understanding of trophic dynamics in river-floodplain systems.

Salinized rivers: degraded systems or new habitats for salt-tolerant faunas?

Anthropogenic salinization of rivers is an emerging issue of global concern, with significant adverse effects on biodiversity and ecosystem functioning. Impacts of freshwater salinization on biota are strongly mediated by evolutionary history, as this is a major factor determining species physiological salinity tolerance. Freshwater insects dominate most flowing waters, and the common lotic insect orders Ephemeroptera (mayflies), Plecoptera (stoneflies) and Trichoptera (caddisflies) are particularly salt-sensitive. Tolerances of existing taxa, rapid adaption, colonization by novel taxa (from naturally saline environments) and interactions between species will be key drivers of assemblages in saline lotic systems. Here we outline a conceptual framework predicting how communities may change in salinizing rivers. We envision that a relatively small number of taxa will be saline-tolerant and able to colonize salinized rivers (e.g. most naturally saline habitats are lentic; thus potential colonizers would need to adapt to lotic environments), leading to depauperate communities in these environments.

Individual Differences in Toddlers' Prosociality: Experiences in Early Relationships Explain Variability in Prosocial Behavior.

Latent class logistic regression analysis was used to investigate sources of individual differences in profiles of prosocial behavior. Eighty-seven 18-month-olds were observed in tasks assessing sharing with a neutral adult, instrumentally helping a neutral adult, and instrumentally helping a sad adult. Maternal mental state language (MSL) and maternal sensitivity were also assessed. Despite differing motivational demands across tasks, we found consistency in children's prosocial behavior with three latent classes: no prosocial behavior, moderate prosocial behavior, and frequent instrumental helping across emotional situations. Maternal sensitivity, MSL, and their interaction predicted toddlers' membership in the classes. These findings evidence moderate consistency in early prosocial behaviors and suggest that these capacities are motivated in early relationships with caregivers.

Children's perceptions of emotion regulation strategy effectiveness: links with attachment security.

Six- and nine-year-old children (N = 97) heard illustrated stories evoking anger in a story character and provided evaluations of the effectiveness of eight anger regulation strategies. Half the stories involved the child's mother as social partner and the other half involved a peer. Attachment security was assessed via the Security Scale. Children reported greater effectiveness for seeking support from adults and peers in the peer context than the mother context, but perceived venting as more effective with mothers. Children with higher security scores were more likely to endorse problem solving and less likely to endorse aggression in both social contexts than those with lower security scores. Early evidence for gender differences was found in that boys endorsed the effectiveness of distraction while girls endorsed venting their emotion.
