Studies on microbiome diversity are flooding the current literature, yet lessons from ecology clearly demonstrate that diversity is just one factor to consider when analyzing an ecosystem, along with its stability, structure and function. Measures of diversity may be a useful tool for interpreting metagenomic data but the question remains as to how informative they are and what insight they may...
The natural world is increasingly defined by change. Within the next 100 years, rising atmospheric CO₂ concentrations will continue to increase the frequency and magnitude of extreme weather events. Simultaneously, human activities are reducing global biodiversity, with current extinction rates at ~1,000 × what they were before human domination of Earth's ecosystems. The co-occurrence of these ...
Proper and effective management of soil nutrients requires assessment of their variability at the field scale. We compare the effects of lime amendment rate on the spatial variability of three macronutrient forms (NH4 (+)-N, Olsen P, and Mehlich-1 K) in a paddy soil at three different dates during the growth period of a rice crop. The field work was carried out near Corrientes, Argentina. Lime ...
Nearly all weed control methods influence both the abiotic and biotic components of the ecosystem. These include the following: mechanical control techniques; cultural practices such as grazing, burning, flooding or revegetation, the introduction of biological weed control agents; and the use of chemicals. This paper reviews many of the risks of weed control and, in some cases, suggests prevent...
Intense rainfall in urban areas often generates both pluvial flooding due to the limited capacity of drainage systems, as well as fluvial flooding caused by deluges from river channels. The concurrence of pluvial and fluvial flooding can aggravate their (individual) potential damages. To analyse the impact caused by individual and composite type of flooding, the SIPSON/UIM model, an integrated ...
The kymograph, one of the main devices used in early experimental phonetics, was quickly exploited to describe the sounds of languages in sub-Saharan Africa. By 1926, Doke used this device in its phonetics Zulu, to objectify the description of the main sounds of this language: vowels with epiglottal friction; the difference between aspirated and non-aspirated explosive consonants and consonants...
The ultimate opening is an operator based on numerical residues. It extracts the significant structures from an image, without a priori size information. Its direct implementation, derived from its definition is time-consuming. In this paper we propose an efficient implementation of ultimate criteria opening, based on a flooding process.
As farmland systems vary over space and time (season and year), accurate and updated maps of paddy rice are needed for studies of food security and environmental problems. We selected a wheat-rice double-cropped area from fragmented landscapes along the rural-urban complex (Jiangsu Province, China) and explored the potential utility of integrating time series optical images (Landsat-8, MODIS) a...
Many bedrock canyons on Earth and Mars were eroded by upstream propagating headwalls, and a prominent goal in geomorphology and planetary science is to determine formation processes from canyon morphology. A diagnostic link between process and form remains highly controversial, however, and field investigations that isolate controls on canyon morphology are needed. Here we investigate the origi...
