Predation plays an important role in mediating the coexistence and the community structure of rotifera. In response to predation stresses, prey rotifers develop morphological defenses and change their life-history strategy for the reallocation of energy investment. Yet, how these changes respond to different total energy ingestion remains largely unknown. In the present study, we investigated the life-table demographic, population growth and morphological parameters of Brachionus calyciflorus in response to various densities of Asplanchna sieboldi at two food levels (1...

Reducing costs and increasing benefits for rural communities coexisting with large carnivores is necessary for conservation of jaguar (Panthera onca) and puma (Puma concolor). To design acceptable incentives, stakeholders must be involved in the process. We conducted an innovative structured group communication process, based on a Delphi technique, as a template for identifying potential incentives. Community workshops with 133 members of 7 communities and iterative surveys with 25 multidisciplinary experts from government, NGOs and academia provided iterative data to design a plan of incentives through 4 rounds of discussion...

Because of the failure of many promising therapeutics identified in preclinical evaluation, funding sources have established guidelines for increased rigor in animal evaluations. The myasthenia gravis (MG) community of scientists has developed guidelines for preclinical assessment for potential MG treatments. Here, we provide a focused summary of these recommendations and the role of complement in disease development in experimental models of MG.

Cariogenic biofilms are highly structured microbial communities embedded in an extracellular matrix, a multifunctional scaffold that is essential for the existence of the biofilm lifestyle and full expression of virulence. The extracellular matrix provides the physical and biological properties that enhance biofilm adhesion and cohesion, as well as create a diffusion-modulating milieu, protecting the resident microbes and facilitating the formation of localized acidic pH niches. These biochemical properties pose significant challenges for the development of effective antibiofilm therapeutics to control dental caries...

Emotion mobilizes and demobilizes a social movement while the movement itself impacts people's emotions. An evidence base is needed for developing timely emotion-focused counseling services for affected populations worldwide. This experience sampling study investigated the impact of a social movement on everyday emotional reactivity, variability, instability, and persistence, and whether and how these predicted subsequent psychological distress and well-being among 108 community-dwelling adults. Fifty-four participants reported momentary events and emotions 5 times daily over 7 days during the Umbrella Movement in Hong Kong...

Background: Globally, substantial health inequities exist with regard to maternal, newborn and reproductive health. Lack of access to good quality care-across its many dimensions-is a key factor driving these inequities. Significant global efforts have been made towards improving the quality of care within facilities for maternal and reproductive health. However, one critically overlooked aspect of quality improvement activities is person-centered care. Main body: The objective of this paper is to review existing literature and theories related to person-centered reproductive health care to develop a framework for improving the quality of reproductive health, particularly in low and middle-income countries...

Many of the outstanding questions in disease ecology and evolution call for combining observation of natural host-parasite populations with experimental dissection of interactions in the field and the laboratory. The "rewilding" of model systems holds great promise for this endeavor. Here, we highlight the potential for development of the nematode Caenorhabditis elegans and its close relatives as a model for the study of disease ecology and evolution. This powerful laboratory model was disassociated from its natural habitat in the 1960s...
