TL;DR: Vessel traits affect growth and wood density affects growth and survival of large trees in the field, and are important components of the performance and life history strategies of tropical tree species.
Abstract: Summary •In a comparative study of 42 rainforest tree species we examined relationships amongst wood traits, diameter growth and survival of large trees in the field, and shade tolerance and adult stature of the species •The species show two orthogonal axes of trait variation: a primary axis related to the vessel size–number trade-off (reflecting investment in hydraulic conductance vs hydraulic safety) and a secondary axis related to investment in parenchyma vs fibres (storage vs strength) Across species, growth rate was positively related to vessel diameter and potential specific hydraulic conductance (Kp), and negatively related to wood density Survival rate was only positively related to wood density •Light-demanding species were characterized by low wood and vessel density and wide vessels Tall species were characterized by wide vessels with low density and large Kp Hydraulic traits were more closely associated with adult stature than with light demand, possibly because tall canopy species experience more drought stress and face a higher cavitation risk •Vessel traits affect growth and wood density affects growth and survival of large trees in the field Vessel traits and wood density are therefore important components of the performance and life history strategies of tropical tree species

TL;DR: Stem turnover rates were poor predictors of species turnover rates, particularly at longer time-intervals, and dynamic changes in basal area within stands, on the other hand, generally followed chronosequence trends.
Abstract: Rates of change in tree communities following major disturbances are determined by a complex set of interactions between local site factors, landscape history and structure, regional species pools and species life histories. Our analysis focuses on vegetation change following abandonment of agricultural fields or pastures, as this is the most extensive form of major disturbance in Neotropical forests. We consider five tree community attributes: stem density, basal area, species density, species richness and species composition. We describe two case studies, in northeastern Costa Rica and Chiapas, Mexico, where both chronosequence and annual tree dynamics studies are being applied. These case studies show that the rates of change in tree communities often deviate from chronosequence trends. With respect to tree species composition, sites of different ages differ more than a single site followed over time through the same age range. Dynamic changes in basal area within stands, on the other hand, generally followed chronosequence trends. Basal area accumulation was more linked with tree growth rates than with net changes in tree density due to recruitment and mortality. Stem turnover rates were poor predictors of species turnover rates, particularly at longer time-intervals. Effects of the surrounding landscape on tree community dynamics within individual plots are poorly understood, but are likely to be important determinants of species accumulation rates and relative abundance patterns.

TL;DR: The specific activity of the mesophilic granular sludge was improved under psychrophilic conditions, which indicates that there was growth and enrichment of methanogens and acetogens in the anaerobic system.

Journal ArticleDOI
TL;DR: The authors examines conceptual differences between sustainable and ecological intensification as used in research, development, policy and the industry, particularly with respect to the balance between agriculture and nature, and compares different discourses on models of intensification that differ in the role nature plays in the actual design of the systems.

TL;DR: In this paper, the authors argue that the social practices model, derived from structuration theory, offers a feasible alternative in this respect, because the model makes possible a sociological, "contextual" approach to consumption behaviors and lifestyles.
Abstract: Within environmental social sciences, the authors believe that the analysis of sustainable production should be complemented by bringing in issues of sustainable consumption and lifestyles. It is possible to place a stronger emphasis on consumption issues without lapsing into the socio-psychological models that were used for so long in the analyses of environmental (un)friendly behaviors of citizen-consumers. The article argues that the social practices model, derived from structuration theory, offers a feasible alternative in this respect, because the model makes possible a sociological, "contextual" approach to consumption behaviors and lifestyles. The kind of questions the social practices model generates for empirical research are illustrated using the example of domestic consumption of utility products and services. By discussing a number of pilot studies within Dutch environmental policymaking, the future agenda of the politics of sustainable consumption is explored and commented upon.
