Vegetation plays a leading role in ecosystems. Plant communities are the main components of ecosystems. Green plants in ecosystems are the primary producers, and they provide the living organic matter...
Background: Although the prevalence of a body mass index [BMI (in kg/m2)] ≥30 has tripled among US adults since the 1960s, BMI is only moderately correlated with body fatness. Because skinfolds can mo...
We update and reevaluate the scientific information on the distribution, history, and causes of continental shelf hypoxia that supports the 2001 Action Plan for Reducing, Mitigating, and Controlling ...
Many authors have claimed to have found long-term trends in f0 F2 , or the lack thereof, for different stations. Such investigations usually involve gross assumptions about the variation of f0 F2 with...
The first part of the paper is directed to the investigation of the practical importance of possible longterm trends in the F2-layer for ionospheric prediction models. Using observations of about 50 d...
One of the typical methods for the identification of seismo-hydrological effects is to monitor changes in the free gas flow throughout springs or mofettes. For several years, the gas flow regime of m...
We examine how species richness and species-specific plant density (number of species and number of individuals per species, respectively) vary within community size frequency distributions and across...
The lower and middle atmosphere present long-term variations in temperature and other parameters linked to anthropogenic sources, such as the increase in greenhouse gases concentration since the start...
This is an interesting and useful compendium written by well established oceanographers. It will be of value to marine researchers and administrators. The editors deserve our thanks for a coherent att...
Seawater is a dilute salt solution. The salt or salinity is reduced or elevated as freshwater is added or removed, respectively, through precipitation, evaporation, and sea-ice melting and freezing, a...
Changing atmospheric composition due to human activities, primarily carbon dioxide (CO2) emissions from fossil fuel burning, is already impacting ocean circulation, biogeochemistry, and ecology, and m...
The "Ridge" community has pioneered not only scientific exploration of and research on the global mid-ocean ridge system but also innovative and attractive ways of reaching out to the public with fasc...
The aims of the present study were (i) to evaluate trends in runoff from small forested catchments of the GEOMON (GEOchemical MONitoring) network during the period 1994–2011, and (ii) to estimate the ...
The floods experienced recently in the Czech Republic gave rise to numerous discussions over the changed environment and related potential impacts on the rainfall and runoff processes. The main aim of...
Background: Marked increases in mean body mass index (BMI) and prevalence of obesity and overweight in the United States are well known. However, whether these average increases were accompanied by ch...
