In 2013, Benin developed strategies to control neglected tropical diseases and one of the first step was the disease mapping of the entire country in order to identify endemic districts of schistosomiasis and soil transmitted helminths (STH). This study was carried out in 30 of the 77 districts of Benin. Of these 30 districts 22 were previously treated for Lymphatic Filariasis (LF) using the Iv...

We present an example of a tool for quantifying the burden, the population in need of intervention and resources need to contribute for the control of soil-transmitted helminth (STH) infection at multiple administrative levels for the region of Latin America and the Caribbean (LAC). The tool relies on published STH prevalence data along with data on the distribution of several STH transmission ...

For 2321 species of shelled gastropods of the northeastern Pacific, the ratio of carnivorous to non-carnivorous species (C/NC ratio), computed for each degree of latitude, reveals striking spatial changes, with tropical and arctic areas characterized by high values and with the midlatitudes having the lowest ratios. This latitudinal trend is markedly different from trends for terrestrial clades...

However, many existing diagnostics for the tropical belt edge latitudes are subjective, with trends in the width of the tropical belt sensitive to the value of the parameters chosen. Further, it is unknown if widely-used reanalysis products reliably capture the seasonal cycle and interannual variability of the width of the tropical belt. Unfortunately, the dearth of wind observations in the tro...

The number of people in food crisis around the world is increasing, exacerbated by COVID-19, conflict, and climate change. Major crop yields are projected to decrease low-latitude regions, making tropical sub-tropical systems particularly vulnerable. Increased cultivation breadfruit ( Artocarpus altilis ), a neglected underutilized species (NUS), has potential enhance resilience overall sustain...

The dynamics of ionospheric troughs during intense geomagnetic storms is considered in this paper. study based on electron density measurements at CHAMP satellite altitudes 405–465 km the period from 2000 to 2002. A detailed analysis four with Kp 5+ 9? presented. Three were identified: sub-auroral, mid-latitude, and low-latitude. sub-auroral trough usually defined as main (MIT). mid-latitude ob...

Stratospheric aerosol profiles at high northern latitudes from the Stratospheric Aerosol Measurement (SAM) II experiment are used to document the aerosol maxima that occur in the major wintertime anticyclones. Fourteen years (1978–1991) of 1 mm extinction are used to calculate median values for each season in bins of 58 latitude by 308 longitude by 1 km altitude. Longitude-altitude sections of ...

PURPOSE OF REVIEW With the London Declaration on neglected tropical disease (NTD), we are entering a new era of combating NTDs. However, the worldwide prospects of increased mass drug administration (MDA) treatments warrant caution on the development of anthelmintic resistance. In this review, we discuss the practical implications of MDA programs on the development of anthelmintic resistance in...

During the late 1800s, when trees were cut by handsaw and the logs floated down river by the hundreds to be milled, they occasionally jammed. Skilled lumberjacks could often identify a single ‘‘key log,’’ which, once released, opened the way for all the logs to continue their journey. The study by Anderson and colleagues in this issue of PLOS Neglected Tropical Diseases [1] points to the presen...
