Age differences in everyday stressor-related negative affect: A coordinated analysis.

Psychol Aging 2018 Dec 13. Epub 2018 Dec 13.

Department of Biobehavioral Health and Medicine.

Advancing age is often characterized by preserved or even enhanced emotion regulation, which is thought to manifest in terms of age-related reductions in the within-person association between stressors and negative affect. Existing research from ecological momentary assessment and end-of-day daily diary studies examining such age-related benefits have yielded mixed results, potentially due to differences in samples, design, and measurement of everyday stressors and negative affect. We conducted a coordinated analysis of 5 ecological momentary assessments and 2 end-of-day daily diary studies to examine adult age differences in the within-person association between everyday stressors and negative affect.

ECNU-Alberta Joint Lab for Biodiversity Study, Tiantong National Station for Forest Ecosystem Research, East China Normal University, 200241, Shanghai.

Climate is widely recognised as an important determinant of the latitudinal diversity gradient. However, most existing studies make no distinction between direct and indirect effects of climate, which substantially hinders our understanding of how climate constrains biodiversity globally. Using data from 35 large forest plots, we test hypothesised relationships amongst climate, topography, forest structural attributes (stem abundance, tree size variation and stand basal area) and tree species richness to better understand drivers of latitudinal tree diversity patterns.

Trait-based ecology of terrestrial arthropods.

Biol Rev Camb Philos Soc 2018 Dec 13. Epub 2018 Dec 13.

Department of Zoology, University of Oxford, Oxford, OX1 3PS, U.K.

In focusing on how organisms' generalizable functional properties (traits) interact mechanistically with environments across spatial scales and levels of biological organization, trait-based approaches provide a powerful framework for attaining synthesis, generality and prediction. Trait-based research has considerably improved understanding of the assembly, structure and functioning of plant communities. Further advances in ecology may be achieved by exploring the trait-environment relationships of non-sessile, heterotrophic organisms such as terrestrial arthropods, which are geographically ubiquitous, ecologically diverse, and often important functional components of ecosystems.

Risk Factors and Rates of Hepatitis B Virus Infection among Municipal Waste Management Workers and Scavengers in Ilorin, Kwara State, Nigeria.

J Health Pollut 2016 Dec 22;6(12):1-6. Epub 2016 Dec 22.

Centre for Ecological and Environmental Research Management Studies, Kwara State University, Malete, Nigeria.

Background: Poor municipal waste management, including waste treatment and disposal methods, threatens the environment and public health in most developing countries. Lack of proper municipal waste segregation and transportation techniques has increased the potential for the transmission of pathogens such as hepatitis B virus (HBV).

Objectives: This study addressed issues relating to the potential risk of infectious diseases and prevalence of HBV among municipal waste workers and scavengers in Ilorin metropolis, Nigeria. Read More

Combined effects of flow speed and sub-lethal insecticide exposure on predator-prey interactions between the California killifish and an infaunal polychaete.

Ecotoxicology 2018 Dec 13. Epub 2018 Dec 13.

Department of Biology and Coastal and Marine Institute, San Diego State University, 5500 Campanile Drive, San Diego, CA, 92182-4614, USA.

Hydrodynamics and pollution affect estuarine populations, but their ecological effects have rarely been studied in combination. We conducted two laboratory experiments to quantify whether predator-prey interactions between California killifish, Fundulus parvipinnis, and the polychaete Polydora cornuta vary with flow speed and chlorpyrifos exposure. In one experiment, only F. Read More

Allelopathic effects of Canada goldenrod leaf extracts on the seed germination and seedling growth of lettuce reinforced under salt stress.

Ecotoxicology 2018 Dec 13. Epub 2018 Dec 13.

Institute of Environment and Ecology, Academy of Environmental Health and Ecological Security & School of the Environment and Safety Engineering, Jiangsu University, 212013, Zhenjiang, P. R. China.

Allelopathic effects on the seed germination and seedling growth of the natives play a crucial role in the successful invasion of numerous invaders. Meanwhile, soil salinity is an emerging driver of the spread of many invaders, especially in the colonization of saline habitats. Thus, the allelopathic effects of the invaders on the seed germination and seedling growth of the natives may be altered or even reinforced under salt stress. Read More

Adolescent Depression and Substance Use: the Protective Role of Prosocial Peer Behavior.

J Abnorm Child Psychol 2018 Dec 14. Epub 2018 Dec 14.

University of Tennessee, Center for Behavioral Health Research, Henson Hall, 213, Knoxville, TN, 37996-3332, USA.

Adolescents with depression disorders have higher rates of substance use. In order to advance contextually relevant mental health interventions, basic research is needed to test social ecological mechanisms hypothesized to influence adolescent depression and substance use. Accordingly, we conducted growth curve modeling with a sample of 248 urban adolescents to determine if depression's effect on substance use was dependent upon peer network health (sum of peer risk and protective behaviors) and activity space risk (likelihood of high-risk behaviors at routine locations).

Integrating design thinking with sustainability science: a Research through Design approach.

Sustain Sci 2018 20;13(6):1565-1587. Epub 2018 Aug 20.

1School of Earth and Environmental Science, The University of Queensland, Brisbane, QLD Australia.

Design disciplines have a long history of creating well-integrated solutions to challenges which are complex, uncertain and contested by multiple stakeholders. Society faces similar challenges in implementing the Sustainable Development Goals, so design methods hold much potential. While principles of good design are well established, there has been limited integration of design thinking with sustainability science. Read More
