    Biogeographic legacies - Forest classification - Forest functional similarity - Phylogenetic community distance - Tropical forests

    Knowledge about the biogeographic affinities of the world's tropical forests helps to better understand regional differences in forest structure, diversity, composition, and dynamics. Such understanding will enable anticipation of region-specific responses to global environmental change. Modern phylogenies, in combination with broad coverage of species inventory data, now allow for global biogeographic analyses that take species evolutionary distance into account. Here we present a classification of the world's tropical forests based on their phylogenetic similarity. We identify five principal floristic regions and their floristic relationships: (i) Indo-Pacific, (ii) Subtropical, (iii) African, (iv) American, and (v) Dry forests. Our results do not support the traditional neo- versus paleotropical forest division but instead separate the combined American and African forests from their Indo-Pacific counterparts. We also find indications for the existence of a global dry forest region, with representatives in America, Africa, Madagascar, and India. Additionally, a northern-hemisphere Subtropical forest region was identified with representatives in Asia and America, providing support for a link between Asian and American northernhemisphere forests.

    Matrix models for Arctic Calanus species: using experimental toxicity data for oil components to assess population level effects

    When assessing population level effects of oil spills, data are required on
    both the life history parameters of species and toxicity end-points. We
    constructed age-structured matrix models for Arctic copepods to predict
    the impact of potential oil spills at the population level. Two matrix models
    were defined, representing the Arctic shelf species Calanus glacialis,
    spawning in waters all around the Arctic shelf and C. hyperboreus, the
    Arctic oceanic species connected to deep-sea, with a 2x2 and a 4x4 matrix
    model, respectively, which refer to a 2-year and a 4-year life-cycle. The
    post-breeding models included egg production and mortality rates as lifehistory
    parameters. Relevant Arctic conditions were taken into account by
    defining a winter diapause period, where no mortality is assumed to take
    place. Toxicity information on exposure to oil and oil-components was
    collected for Calanus species. It appeared that the life-history parameter
    with the highest elasticity in the model was the adult survival, meaning that
    changes therein have most impact on the output, i.e. population size. This
    is because the adult class produces offspring. Published data on mortality
    rates in field and laboratory studies appeared too high to maintain viable
    populations. Therefore, we modified these parameter values such that modeled
    populations became viable. Adequate toxicity information on oil and
    oil components for Calanus species appeared to be scarce, and we therefore
    selected pyrene as a model compound. However, reported end points for
    pyrene were not directly applicable in the matrix model, and we developed
    new approaches to derive a dose-response relationship from the available
    data. Based on the generic matrix models, simulation models using day-today
    calculation steps were developed to test the effects of various oil spill
    scenarios at the population level, taking into account a range of exposure
    concentrations and exposure durations. The results show that the calculated
    population effects are very different, when based on different types
    of effect concentrations (NOEC, LOEC and LC50). We argue that simple
    matrix models are very useful to assess the potential impacts of oil spills
    at the ecological relevant population level, but that scarcity of information
    limits an accurate quantitative assessment. A more realistic estimate of
    natural survival rates and the toxic effects thereupon will allow for a better
    assessment of population level consequences of an oil spill.

    Monitoring of human eating behaviour has been attracting interest over the last few years, as a means to a healthy lifestyle, but also due to its association with serious health conditions, such as eating disorders and obesity. Use of self-reports and other non-automated means of monitoring have been found to be unreliable, compared to the use of wearable sensors. Various modalities have been reported, such as acoustic signal from ear-worn microphones, or signal from wearable strain sensors. In this work, we introduce a new sensor for the task of chewing detection, based on a novel photoplethysmography (PPG) sensor placed on the outer earlobe to perform the task. We also present a processing pipeline that includes two chewing detection algorithms from literature and one new algorithm, to process the captured PPG signal, and present their effectiveness. Experiments are performed on an annotated dataset recorded from 21 individuals, including more than 10 hours of eating and non-eating activities. Results show that the PPG sensor can be successfully used to support dietary monitoring.

    Evaporative cooling - Greenhouse - Natural ventilation - Optimal - Screenhouse - Tomato - Vapor pressure deficit
    The objective of this study was to compare two closed-field plant production environments for tomato cultivation based on optimal vapor pressure deficit (VPD). Experiment was carried out in tropical lowlands of Malaysia by collecting 11 days of sample data during March (2014), from an evaporative cooled Polycarbonate Panel (PP) covered greenhouse and a naturally ventilated Screenhouse (SH). A computer application was designed and used for VPD calculation and data processing with respect to three light conditions (night, sun and cloud). The average and maximum VPD were respectively equal to 0.97 and 3.81 kPa for SH and 1.19 and 5.1 kPa for PP. The largest differences in the VPD of the two environments were between 2.9 and 3.1 kPa and were observed between hours of 12:30 and 17:30 at sun conditions. Results did not show significant differences in the two environments between hours of 00:00 and 8:00, when inside air temperature was between 24 to 26°C, and relative humidity was near 90%. The hypothesis that the PP, compared to SH, provides VPD closer to the optimal range was rejected. Further analysis of the results showed that linear correlations with R2>0.9 exist between daily averaged VPD of each greenhouses. It was concluded that VPD in the SH was closer to the optimal range in the entire days of experiment. The outcome of this study contributes to knowledge-based information for greenhouse growers by addressing questions about trends in VPD data, peak-hours and light conditions associated with maximum and minimum values.

    Co-evolution - Eutrophication - Grazing - Local-adaptation - Plankton

    As blooms of cyanobacteria expand and intensify in freshwater systems globally, there is increasing interest in their ecological effects. In addition to being public health hazards, cyanobacteria have long been considered a poor quality food for key zooplankton grazers that link phytoplankton to higher trophic levels. While past laboratory studies have found negative effects of nutritional constraints and defensive traits (i.e., toxicity and colonial or filamentous morphology) on the fitness of large generalist grazers (i.e., Daphnia), cyanobacterial blooms often co-exist with high biomass of small-bodied zooplankton in nature. Indeed, recent studies highlight the remarkable diversity and flexibility in zooplankton responses to cyanobacterial prey. Reviewed here are results from a wide range of laboratory and field experiments examining the interaction of cyanobacteria and a diverse zooplankton taxa including cladocerans, copepods, and heterotrophic protists from temperate to tropical freshwater systems. This synthesis shows that longer exposure to cyanobacteria can shift zooplankton communities toward better-adapted species, select for more tolerant genotypes within a species, and induce traits within the lifetime of individual zooplankton. In turn, the function of bloom-dominated plankton ecosystems, the coupling between primary producers and grazers, the stability of blooms, and the potential to use top down biomanipulation for controlling cyanobacteria depend largely on the species, abundance, and traits of interacting cyanobacteria and zooplankton. Understanding the drivers and consequences of zooplankton traits, such as physiological detoxification and selective vs. generalist grazing behavior, are therefore of major importance for future studies. Ultimately, co-evolutionary dynamics between cyanobacteria and their grazers may emerge as a critical regulator of blooms.

    Urban Evapotranspiration in a Humid Environment - Orlando, Florida, USA
    Sumner, David M. ; Jacobs, C.M.J. - \ 2016
    In: Headwaters to estuaries: advances in watershed science and management—Proceedings of the Fifth Interagency Conference on Research in the Watersheds. - Asheville, NC, USA : U.S. Department of Agriculture Forest Service, Southern Research Station - p. 246 - 246.
    An areally-integrated assessment of ET ux was obtained using eddy covariance methods over an urban/suburban landscape in the humid sub-tropical environment of Orlando, Florida, USA. Mean annual ET during the 3.5-year study period was 921 mm. On average, ET returned a large fraction of rainfall to the atmosphere (72 percent). But annual rainfall varied much more on a year-to-year basis (922 to 1,746 mm) than did urban ET (843 to 974 mm). Interestingly, 12-month periods of relatively high ET occurred during drier periods and
    12-month periods of relatively low ET occurred during wetter periods. These results may be related to the generally drier atmosphere and less cloud cover that occur during lower rainfall periods. In addition, this largely urban environment is not subject to large soil moisture limitations because of the prevalence of lawn irrigation and lakes. Corroboration of the ET measurements was provided by independent water budgets for two watersheds that make up
    much of the source area for the ET measurements. An urban analogue to the “crop coef€cient” concept was derived for the studied landscape. This metric was combined with an available satellite-based, State of Florida reference ET product ( to provide a method for transferring the results of this study to similar landscapes for other time periods and geographic areas. The results of this investigation in a humid, sub-tropical urban setting
    are compared and contrasted with urban ET estimates for other environments
