In-situ and ex-situ measurements of environmental radioactivity were made on the iThemba LABS (iTL) grounds in South Africa. The MEDUSA and HPGe detector systems were used to make insitu and ex-situ measurements, respectively. The MEDUSA was mounted ∼0.5m above the ground on a 4× 4 vehicle to traverse [at ∼2m · s−1] the accessible portions of the iTL grounds. Spatial data (via a GPS receiver) w...

Studies on the effects of anthropogenic activity on wildlife aim to provide a sound scientific basis for management. However, misinterpretation of the theoretical basis for these studies can jeopardise this objective and lead to management outcomes that are detrimental to the wildlife they are intended to protect. Misapplication of the terms ‘habituation’, ‘sensitisation’ and ‘tolerance’ in imp...

Abstract Earth’s hum at higher frequencies is disturbed substantially by human activity. Anthropogenic noise more evident in than 1 Hz. The power 10 Hz used from January 2020 to early May (mostly first wave of SARS-CoV-2) across various sites the world, show that there a clear decrease during lockdown period. Furthermore, this anthropogenic world COVID-19 period, within which vehicular movement...

The role played by human activity in coastline changes indicates a general tendency of retreating coasts, especially deltaic environments, as a result of the recent trend of sea level rise as well as the blockage of the transfer of sediments towards the coast, especially due to the construction of dams. This is particularly important in deltaic environments which have been suffering a dramatic ...

Madagascar is a biodiversity hotspot threatened by habitat loss, which is detrimental to the future survival of forest-dwelling herpetofauna. For conservation purposes, it is essential to determine how species respond to different types of anthropogenic habitat alteration. We conducted standardized field surveys (a variation of visual encounter survey) to assess species richness, abundance and ...

While anthropogenic impacts on parasitism of wildlife are receiving growing attention, whether these impacts vary in a sex-specific manner remains little explored. Differences between the sexes in the effect of parasites, linked to anthropogenic activity, could lead to uneven sex ratios and higher population endangerment. We sampled 1108 individual bats in 18 different sites across an agricultu...

background: the concentrations and distributions of natural and anthropogenic radioactive materials in soils of the site of rooppur nuclear power plant (rnpp) were investigated with the aim of evaluating the environmental radioactivity and radiation hazard. materials and methods: soil samples were collected from 40 locations in and around the proposed site of rooppur power plant and determined ...

Climate change and anthropogenic factors can alter biodiversity and can lead to changes in community structure and function. Despite the potential impacts, no long-term records of climatic influences on microbial communities exist. The Tibetan Plateau is a highly sensitive region that is currently undergoing significant alteration resulting from both climate change and increased human activity....

by Pavel Povinec, Scott Fowler, and Murdoch Baxter I he Chernobyl nuclear accident in April 1986 had a significant impact on both the terrestrial and marine environments. The total activity of the nuclear debris released was so high (1-2.10 becquerel) that the radioactive fallout distributed widely after the accident actually dominated anthropogenic environmental levels in various parts of the ...

The Lower Pra River Basin (LPRB), located in the forest zone of southern Ghana has experienced changes due to variability in precipitation and diverse anthropogenic activities. Therefore, to maintain the functions of the ecosystem for water resources management, planning and sustainable development, it is important to differentiate the impacts of precipitation variability and anthropogenic acti...
