    Lausanne : Frontiers
    Details
    Keywords: climate ; Climate Change ; marine mammals ; predators ; seabirds ; trophic interactions
    Description / Table of Contents: Climate change affects all components of marine ecosystems. For endothermic top predators, i.e. seabirds and marine mammals, these impacts are often complex and mediated through trophic relationships. In this Research Topic, leading researchers attempt to identify patterns of change among seabirds and marine mammals, and the mechanisms through which climate change drives these changes.

    The Microbial Nitrogen Cycle (2015)
    Lausanne : Frontiers
    Details
    Keywords: nitrogen cycle ; microbial ecology ; nitrogen fixation ; denitrification ; Anammox ; nitrification ; microbiology
    Description / Table of Contents: Nitrogen is an essential element in biological systems, and one that often limits production in both aquatic and terrestrial systems. Due to its requirement in biological macromolecules, its acquisition and cycling have the potential to structure microbial communities, as well as to control productivity on the ecosystem scale. In addition, its versatile redox chemistry is the basis of complex biogeochemical transformations that control the inventory of fixed nitrogen, both in local environments and over geological time. Although many of the pathways in the microbial nitrogen cycle were described more than a century ago, additional fundamental pathways have been discovered only recently. These findings imply that we still have much to learn about the microbial nitrogen cycle, the organisms responsible for it, and their interactions in natural and human environments. Progress in nitrogen cycle research has been facilitated by recent rapid technological advances, especially in genomics and isotopic approaches. In this Research Topic, we reviewed the leading edge of nitrogen cycle research based on these approaches, as well as by exploring microbial processes in modern ecosystems.

    The Microbial Regulation of Global Biogeochemical Cycles (2014)
    Lausanne : Frontiers
    Details
    Keywords: microbial ecology ; biogeochemistry ; stoichiometry ; Climate Change ; soil microbiology ; elemental fluxes ; Respiration ; aquatic microbiology ; microbiology
    Description / Table of Contents: Global biogeochemical cycles of carbon and nutrients are increasingly affected by human activities. So far, modeling has been central for our understanding of how this will affect ecosystem functioning and the biogeochemical cycling of carbon and nutrients. These models have been forced to adopt a reductive approach built on the flow of carbon and nutrients between pools that are difficult or even impossible to verify with empirical evidence. Furthermore, while some of these models include the response in physiology, ecology and biogeography of primary producers to environmental change, the microbial part of the ecosystem is generally poorly represented or lacking altogether. The principal pool of carbon and nutrients in soil is the organic matter. The turnover of this reservoir is governed by microorganisms that act as catalytic converters of environmental conditions into biogeochemical cycling of carbon and nutrients. The dependency of this conversion activity on individual environmental conditions such as pH, moisture and temperature has been frequently studied. On the contrary, only rarely have the microorganisms involved in carrying out the processes been identified, and one of the biggest challenges for advancing our understanding of biogeochemical processes is to identify the microorganisms carrying out a specific set of metabolic processes and how they partition their carbon and nutrient use. We also need to identify the factors governing these activities and if they result in feedback mechanisms that alter the growth, activity and interaction between primary producers and microorganisms. By determining how different groups of microorganisms respond to individual environmental conditions by allocating carbon and nutrients to production of biomass, CO2 and other products, a mechanistic as well as quantitative understanding of formation and decomposition of organic matter, and the production and consumption of greenhouse gases, can be achieved. In this Research Topic, supported by the Swedish research councils' programme "Biodiversity and Ecosystem Services in a Changing Landscape" (BECC), we intend to promote this alternative framework to address how cycling of carbon and nutrients will be altered in a changing environment from the first-principle mechanisms that drive them – namely the ecology, physiology and biogeography of microorganisms – and on up to emerging global biogeochemical patterns. This novel and unconventional approach has the potential to generate fresh insights that can open up new horizons and stimulate rapid conceptual development in our basic understanding of the regulating factors for global biogeochemical cycles. The vision for the research topic is to facilitate such progress by bringing together leading scientists as proponents of several disciplines. By bridging Microbial Ecology and Biogeochemistry, connecting microbial activities at the micro-scale to carbon fluxes at the ecosystem-scale, and linking above- and belowground ecosystem functioning, we can leap forward from the current understanding of the global biogeochemical cycles.

    Global Change and Human Vulnerability to Vector-borne Diseases (2013)
    Lausanne : Frontiers
    Details
    Keywords: vector-borne diseases ; species composition ; mosquitos ; highland malaria ; virus ; larvicidal agent ; global change ; climate ; emerging and re-emerging disease
    Description / Table of Contents: It is well known that several climatic, environmental and socio-demographic changes that have occurred in the last years are some of the most important causes for the emergence/resurgence of vector-borne diseases worldwide. Global change can be defined as the impact of human activity on the fundamental mechanisms of biosphere functioning. Therefore, global change includes not only climate change, but also habitat transformation, water cycle modification, biodiversity loss, synanthropic incursion of alien species into new territories, or introduction of new chemicals in nature. On this respect, some of the effects of global change on vector-borne diseases can be currently evaluated. Globalization has enabled the movement of parasites, viruses and vectors among different countries, or even at intercontinental level. On this regard, it is important to note that the increase of imported malaria cases in different Southern European countries has led to the re-appearance of autochthonous cases of disease transmission. Moreover, the used tire trade, together with global warming, have facilitated the introduction, spread and establishment of potential Dengue tropical vectors, such as Aedes aegypti or Aedes albopictus in temperate areas. Consequently, recently the first Dengue indigenous cases in the last decades have been reported in different Southern areas of North America and Europe. Furthermore, habitat modification, mainly deforestation and transformation of aquatic environments, together with the changes in thermal and rainfall patterns, are two of the key factors to explain the increasing incidence of Leishmaniasis and several tick-borne diseases. The aim of this Research Topic is to cover all related fields with the binomial vector-borne diseases / global change, including basic and applied research, approaches to control measures, explanations of new theories, opinion articles, reviews, etc. To discuss these issues, a holistic and integrative point of view is necessary, which only would be achieved by the close and active participation of specialists on entomology, parasitology, virology and epidemiology. Our objective is to use a systems approach to the problem of global change and vector-borne diseases. To achieve this ambitious goal and to comply with a demand of first-rate scientific and medical interest, we are very keen on asking for the participation of multiple contributors.
