Direct and indirect effects of climate on richness drive the latitudinal diversity gradient in forest trees.

Ecol Lett 2018 Dec 12. Epub 2018 Dec 12.

ECNU-Alberta Joint Lab for Biodiversity Study, Tiantong National Station for Forest Ecosystem Research, East China Normal University, 200241, Shanghai.

Climate is widely recognised as an important determinant of the latitudinal diversity gradient. However, most existing studies make no distinction between direct and indirect effects of climate, which substantially hinders our understanding of how climate constrains biodiversity globally. Using data from 35 large forest plots, we test hypothesised relationships amongst climate, topography, forest structural attributes (stem abundance, tree size variation and stand basal area) and tree species richness to better understand drivers of latitudinal tree diversity patterns.

J Eukaryot Microbiol 2018 Dec 10. Epub 2018 Dec 10.

Postgraduate Program in Biology of Infectious and Parasitic Agents /, Federal University of Pará - PPgBAIP / UFPA. Research Laboratory Carlos Azevedo / Federal Rural University of the Amazon - LPCA / UFRA, Pará, Brazil.

The coccidians of the family Calyptosporidae are parasites of the tissue and organs of fish and aquatic invertebrates, in particular in the tropical region. In contrast with other apicomplexans of the suborder Eimeriorina, the diversity and ecology of the species of the genus Calyptospora have been poorly investigated, resulting in a lacuna that restricts the understanding of the distribution and prevalence of this group of eukaryote microparasites in the Amazon region. In the present study, the integrated comparative analysis of morphological characteristics, histological and structural traits, and the sequences of a fragment of the 18S rRNA gene, provides support for the identification of a new species of Calyptospora, found parasitising the hepatic tissue of the piscivorous blue peacock bass, Cichla piquiti, captured in the reservoir of the Estreito hydroelectric dam on the middle Tocantins River in northern Brazil.

Repeated doses of Praziquantel in Schistosomiasis Treatment (RePST) - single versus multiple praziquantel treatments in school-aged children in Côte d'Ivoire: a study protocol for an open-label, randomised controlled trial.

BMC Infect Dis 2018 Dec 14;18(1):662. Epub 2018 Dec 14.

Department of Parasitology, Leiden University Medical Center, Leiden, the Netherlands.

Background: Large scale administration of the anthelminthic drug praziquantel (PZQ) to at-risk populations is the cornerstone of schistosomiasis control, although persisting high prevalence of infections in some areas and growing concerns of PZQ resistance have revealed the limitations of this strategy. Most studies assessing PZQ efficacy have used relatively insensitive parasitological diagnostics, such as the Kato-Katz (KK) and urine-filtration methods, thereby overestimating cure rates (CRs). This study aims to determine the efficacy of repeated PZQ treatments against Schistosoma mansoni infection in school-aged children in Côte d'Ivoire using the traditional KK technique, as well as more sensitive antigen- and DNA-detection methods.

Insecticide treated nets (ITNs) protect humans against bites from the mosquito vectors that transmit malaria, thereby reducing malaria morbidity and mortality. It has been noted that ITN use leads to a switch from indoor to outdoor feeding among these vectors. It might be expected that outdoor feeding would undermine the effectiveness of ITNs that target indoors vectors, but data are limited. Read More

Spatial and temporal heterogeneity in the structure and function of sediment bacterial communities of a tropical mangrove forest.

Environ Sci Pollut Res Int 2018 Dec 13. Epub 2018 Dec 13.

Wetland Research and Training Centre, Chilika Development Authority, Balugaon, Odisha, 752030, India.

Bacterial communities of mangrove sediments are well appreciated for their role in nutrient cycling. However, spatiotemporal variability in these communities over large geographical scale remains understudied. We investigated sediment bacterial communities and their metabolic potential in an intertidal mangrove forest of India, Bhitarkanika, using high-throughput sequencing of 16S rRNA genes and community-level physiological profiling.

Freshwater neotropical oligochaetes as native test species for the toxicity evaluation of cadmium, mercury and their mixtures.

Ecotoxicology 2018 Dec 13. Epub 2018 Dec 13.

Department of Ecology and Evolutionary Biology, Federal University of São Carlos, Rodovia Washington Luís, km 235, São Carlos, SP, 13565-905, Brazil.

The toxicity of metals, whether isolated or in mixtures, involves changes in biochemical processes as well as in cell membranes, which may lead to deleterious short- and long-term effects on the affected organisms. Among metals, cadmium and mercury stand out due to their abundance in nature, frequent use for industrial activities and biological accumulation, with high levels of residence in trophic chains. Benthic communities are particularly prone to metal pollution since metals usually accumulate in sediments. Read More

Glacial changes in tropical climate amplified by the Indian Ocean.

Sci Adv 2018 Dec 12;4(12):eaat9658. Epub 2018 Dec 12.

National Center for Atmospheric Research, Climate and Global Dynamics Laboratory, 1850 Table Mesa Drive, Boulder, CO 80305, USA.

The mechanisms driving glacial-interglacial changes in the climate of the Indo-Pacific warm pool are poorly understood. Here, we address this question by combining paleoclimate proxies with model simulations of the Last Glacial Maximum climate. We find evidence of two mechanisms explaining key patterns of ocean cooling and rainfall change interpreted from proxy data. Read More

Effect of menstruation on girls and their schooling, and facilitators of menstrual hygiene management in schools: surveys in government schools in three states in India, 2015.

J Glob Health 2019 Jun;9(1):010408

Department of Clinical Sciences, Liverpool School of Tropical Medicine (LSTM), Liverpool, UK.

Background: Lack of menstrual knowledge, poor access to sanitary products and a non-facilitating school environment can make it difficult for girls to attend school. In India, interventions have been developed to reduce the burden of menstruation for school girls by government and non-governmental organizations (NGOs). We sought to identify challenges related to menstruation, and facilitators of menstrual management in schools in three states in India. Read More
