Multifunctional Floating Titania‐Coated Macro/Mesoporous Photocatalyst for Efficient Contaminant Removal
Authors: Zhang Linlin , Xing Zipeng , Zhang Hang , Li Zhenzi , Zhang Xiaodong , Zhang Yan , Li Li , Zhou Wei 
Published: December 2014

AbstractA multifunctional floating photocatalyst consisting of highly active well‐ordered mesoporous TiO2 (OMT) as a catalyst and polyurethane foam (PUF) as a floating substrate is synthesized successfully through a low‐temperature ultrasonic and deposition approach. With the synthesized OMT/PUF composites, the multifunctionality of contaminant adsorption, dye degradation, and heavy metal removal can be achieved simultaneously. The prepared photocatalyst is characterized in detail by X‐ray diffraction, Raman spectroscopy, transmission electron microscopy, scanning electron microscopy, and N2 adsorption. The results indicate that the OMT/PUF presents a hierarchical macro/mesoporous structure, which is favorable for the adsorption and diffusion of pollutants and for the efficient utilization of sunlight. The degradation of several model dyes including rhodamine B, methyl orange, methylene blue, and simultaneous reduction of hexavalent chromium are examined over the floating photocatalysts with sunlight irradiation under certain conditions. A synergistic effect between the degradation of dyes and the reduction of CrVI is observed for the dye‐CrVI coexistence system. This novel floating OMT/PUF photocatalyst is very promising in the field of wastewater treatment.
Exploring Outcomes Related to Anxiety and Depression in Completers of a Randomized Controlled Trial of Complicated Grief Treatment
Authors: Glickman Kim , Shear M. Katherine , Wall Melanie 
Published: December 2014

The present study examines a more fine‐grained analysis of anxiety‐related and depression‐related outcomes amongst a sample of treatment completers who were assigned to complicated grief treatment (CGT) (n = 35) or interpersonal psychotherapy (IPT) (n = 34) in a previously reported randomized controlled trial. We examined effects of antidepressant use and measures of anxiety and depression, focusing especially on guilt related to the death or deceased and grief‐related avoidance in order to further understand the differential effectiveness of CGT and IPT amongst participants who received the full course of treatment. Analyses showed that CGT produced greater reductions in anxiety and depressive symptoms including negative thoughts about the future and grief‐related avoidance. CGT's advantage over IPT in lowering depression was most pronounced amongst those not taking antidepressants. Our results further elucidate CGT effects and support the idea that CG and major depressive disorder are distinct conditions. Copyright © 2014 John Wiley & Sons, Ltd.Key Practitioner Message

Targeted treatment for complicated grief (CG) produces benefits in associated mood and anxiety symptoms and CG symptoms.
Amongst patients with CG, interpersonal psychotherapy seems relatively ineffective in ameliorating depressive symptoms.
Grief‐related depressive symptoms may not respond to standard treatments unless CG symptoms are also addressed.
Reducing grief‐related symptoms, such as anxieties about the future, guilt related to the death or deceased and avoidance of reminders of the loss may be important aspects in reducing CG.
Cryptanalysis and improvement of a three‐party password‐based authenticated key exchange protocol with user anonymity using extended chaotic maps
Authors: Farash Mohammad Sabzinejad , Attari Mahmoud Ahmadian , Kumari Saru 
Published: December 2014

SummaryThree‐party password‐authenticated key exchange (3PAKE) protocols allow two clients to agree on a secret session key through a server via a public channel. 3PAKE protocols have been designed using different arithmetic aspects including chaotic maps. Recently, Lee et al. proposed a 3PAKE protocol using Chebyshev chaotic maps and claimed that their protocol has low computation and communication cost and can also resist against numerous attacks. However, this paper shows that in spite of the computation and communication efficiency of the Lee et al. protocol, it is not secure against the modification attack. To conquer this security weakness, we propose a simple countermeasure, which maintains the computation and communication efficiency of the Lee et al. protocol.

A general model of intra‐annual tree growth using dendrometer bands
Authors: McMahon Sean M. , Parker Geoffrey G. 
Published: December 2014

AbstractTree growth is an important indicator of forest health, productivity, and demography. Knowing precisely how trees' grow within a year, instead of across years, can lead to a finer understanding of the mechanisms that drive these larger patterns. The growing use of dendrometer bands in research forests has only rarely been used to measure growth at resolutions finer than yearly, but intra‐annual growth patterns can be observed from dendrometer bands using precision digital calipers and weekly measurements. Here we present a workflow to help forest ecologists fit growth models to intra‐annual measurements using standard optimization functions provided by the R platform. We explain our protocol, test uncertainty in parameter estimates with respect to sample sizes, extend the optimization protocol to estimate robust lower and upper annual diameter bounds, and discuss potential challenges to optimal fits. We offer R code to implement this workflow. We found that starting values and initial optimization routines are critical to fitting the best functional forms. After using a bounded, broad search method, a more focused search algorithm obtained consistent results. To estimate starting and ending annual diameters, we combined the growth function with early and late estimates of beginning and ending growth. Once we fit the functions, we present extension algorithms that estimate periodic reductions in growth, total growth, and present a method of controlling for the shifting allocation to girth during the growth season. We demonstrate that with these extensions, an analysis of growth response to weather (e.g., the water available to a tree) can be derived in a way that is comparable across trees, years, and sites. Thus, this approach, when applied across broader data sets, offers a pathway to build inference about the effects of seasonal weather on growth, size‐ and light‐dependent patterns of growth, species‐specific patterns, and phenology.
Optimizing passive acoustic sampling of bats in forests
Authors: Froidevaux Jérémy S. P. , Zellweger Florian , Bollmann Kurt , Obrist Martin K. 
Published: December 2014

AbstractPassive acoustic methods are increasingly used in biodiversity research and monitoring programs because they are cost‐effective and permit the collection of large datasets. However, the accuracy of the results depends on the bioacoustic characteristics of the focal taxa and their habitat use. In particular, this applies to bats which exhibit distinct activity patterns in three‐dimensionally structured habitats such as forests. We assessed the performance of 21 acoustic sampling schemes with three temporal sampling patterns and seven sampling designs. Acoustic sampling was performed in 32 forest plots, each containing three microhabitats: forest ground, canopy, and forest gap. We compared bat activity, species richness, and sampling effort using species accumulation curves fitted with the clench equation. In addition, we estimated the sampling costs to undertake the best sampling schemes. We recorded a total of 145,433 echolocation call sequences of 16 bat species. Our results indicated that to generate the best outcome, it was necessary to sample all three microhabitats of a given forest location simultaneously throughout the entire night. Sampling only the forest gaps and the forest ground simultaneously was the second best choice and proved to be a viable alternative when the number of available detectors is limited. When assessing bat species richness at the 1‐km2 scale, the implementation of these sampling schemes at three to four forest locations yielded highest labor cost‐benefit ratios but increasing equipment costs. Our study illustrates that multiple passive acoustic sampling schemes require testing based on the target taxa and habitat complexity and should be performed with reference to cost‐benefit ratios. Choosing a standardized and replicated sampling scheme is particularly important to optimize the level of precision in inventories, especially when rare or elusive species are expected.
Bryozoans are returning home: recolonization of freshwater ecosystems inferred from phylogenetic relationships
Authors: Koletić Nikola , Novosel Maja , Rajević Nives , Franjević Damjan 
Published: December 2014

AbstractBryozoans are aquatic invertebrates that inhabit all types of aquatic ecosystems. They are small animals that form large colonies by asexual budding. Colonies can reach the size of several tens of centimeters, while individual units within a colony are the size of a few millimeters. Each individual within a colony works as a separate zooid and is genetically identical to each other individual within the same colony. Most freshwater species of bryozoans belong to the Phylactolaemata class, while several species that tolerate brackish water belong to the Gymnolaemata class. Tissue samples for this study were collected in the rivers of Adriatic and Danube basin and in the wetland areas in the continental part of Croatia (Europe). Freshwater and brackish taxons of bryozoans were genetically analyzed for the purpose of creating phylogenetic relationships between freshwater and brackish taxons of the Phylactolaemata and Gymnolaemata classes and determining the role of brackish species in colonizing freshwater and marine ecosystems. Phylogenetic relationships inferred on the genes for 18S rRNA, 28S rRNA, COI, and ITS2 region confirmed Phylactolaemata bryozoans as radix bryozoan group. Phylogenetic analysis proved Phylactolaemata bryozoan's close relations with taxons from Phoronida phylum as well as the separation of the Lophopodidae family from other families within the Plumatellida genus. Comparative analysis of existing knowledge about the phylogeny of bryozoans and the expansion of known evolutionary hypotheses is proposed with the model of settlement of marine and freshwater ecosystems by the bryozoans group during their evolutionary past. In this case study, brackish bryozoan taxons represent a link for this ecological phylogenetic hypothesis. Comparison of brackish bryozoan species Lophopus crystallinus and Conopeum seurati confirmed a dual colonization of freshwater ecosystems throughout evolution of this group of animals.
Ecophysiological responses to different forest patch type of two codominant tree seedlings

Published: December 2014

AbstractAccording to gap‐phase dynamics theory, forests can be divided into four distinct patch types: gap patch (G), building patch (B), mature patch (M), and degeneration patch (D). Varying light conditions across patch types are one of the most important factors affecting the coexistence of vegetation. Mechanisms of coexistence can be understood through detailed knowledge of ecophysiological responses of codominant tree seedlings to patch types. The following study was conducted to determine ecophysiological responses of Cyclobalanopsis glauca (an evergreen broad‐leaved species) and Bothrocaryum controversum (a deciduous broad‐leaved species) to four different patch types. During the gap‐phase dynamics, light intensity and the magnitude of change in the four different patches followed the order of: G > B > D > M. Both species had the greatest photosynthetic capacity in the G patch. Dry leaf mass per area (LMA), Chlorophyll a + b concentration (Chl), carotenoids (Car), and nitrogen content per area (Na) all responded to changes in light across patch type, but B. controversum showed greater sensitivity and changes than C. glauca. From G to M patch, the maximal quantum efficiency of PSII (Fv/Fm) had a larger variation magnitude for B. controversum than for C. glauca. From G to M patch, B. controversum showed significant changes in gas exchange, while C. glauca showed only small changes. Ecophysiological trait partitioning of response to light in different patches provides a possible explanation of a coexistence mechanism.
