Title Human activities might influence oncogenic processes in wild animal populations Type Journal Article
Year 2018 Publication Nature Ecology & Evolution Abbreviated Journal Nat Ecol Evol
Volume (up) 2 Issue Pages 1065-1070
Keywords Commentary; Animals
Abstract Based on the abundant studies available on humans showing clear associations between rapid environmental changes and the rate of neoplasia, we propose that human activities might increase cancer rate in wild populations through numerous processes. Most of the research on this topic has concentrated on wildlife cancer prevalence in environments that are heavily contaminated with anthropogenic chemicals. Here, we propose that human activities might also increase cancer rate in wild populations through additional processes including light pollution, accidental (for example, human waste) or intentional (for example, bird feeders) wildlife feeding (and the associated change of diet), or reduction of genetic diversity in human-impacted habitats. The human species can thus be defined as an oncogenic species, moderating the environment in the way that it causes cancer in other wild populations. As human impacts on wildlife are predicted to increase rather than decrease (for example, in the context of urbanization), acknowledging the possible links between human activity and cancer in wild populations is crucial.

Title Optimization of Urban Street Lighting Conditions Focusing On Energy Saving, Safety and Users’ Needs Type Journal Article
Year 2018 Publication Contemporary Urban Affairs Abbreviated Journal
Volume (up) 2 Issue 3 Pages 112-121
Keywords Lighting; Economics; Planning
Abstract The outdoor lighting constitutes a significant part of the night activities of people in contemporary cities. Nevertheless, in many cases, this may result in the increasing and irrational use of it affecting the users of public areas, the environment and driving safety. The subject of this paper is to extend the discussion on the subject, to provide answers and to suggest methods for the improvement of the existing conditions in urban street lighting through the use of new technologies and smart lighting management systems, with the aim of achieving a smooth relationship between the user’s needs, safety, sustainability, quality of life and energy saving.

Title Urban Intensities. The Urbanization of the Iberian Mediterranean Coast in the Light of Nighttime Satellite Images of the Earth Type Journal Article
Year 2018 Publication Urban Science Abbreviated Journal Urban Science
Volume (up) 2 Issue 4 Pages 115
Keywords Remote Sensing; Tourism
Abstract The contribution shares the approach of critical urban studies that have conceptualized urbanization more as a process than as a sum of spatial forms. Thus, the contribution studies the urbanization process not only from the point of view of the physical occupation of land but also considers changes in the intensity of the uses of space. To fulfill this aim, the new sources of nocturnal satellite images are particularly useful. These allow us to observe the intensity of urban uses both in terms of their distribution over space and their recurrence over time. The research focuses on the Iberian Mediterranean coast and permits the verification of the intensity of the urban uses of the space for the whole of this area and their seasonal variations throughout the year. The source of the study are the nighttime satellite images of the Earth for the 2012–2017 period from the NASA SNPP satellite equipped with the VIIRS-DNB instrument. By establishing a threshold of urban light the research shows that those districts with the greatest extensions of urban light do not necessarily correspond with the most densely populated areas. Similarly the absence of urban light does not necessarily indicate the absence of urban uses. Finally, the variations of intensity of light prove to be a good indicator of seasonal variations of activity in tourist areas.

Title Differential Drift in Menarcheal Age in Blind and Sighted Girls Type Journal Article
Year 2018 Publication Gynaecology and Perinatology Abbreviated Journal
Volume (up) 2 Issue 4 Pages 333-339
Keywords Human Health
Abstract Our survey data show that menarcheal age, both in sighted and blind girls has drifted towards younger years compared to 50 years back, however, in sighted girls it has gone further down compared to blind girls. In this paper we have explained the reasons, why it is so? For the comparison sake we were very careful to select sighted and blind girls from the same geographical region, socio-economical and education status and food habits. Taking into consideration, our earlier hypothesis, “blind women and breast cancer”, here also we propose that only the photo regulatory system for hormonal axis is responsible for differential lowering of Menarcheal age in sighted and blind girls, since all other regulatory factors are same in both the groups.

Title Adaptive changes in sexual signalling in response to urbanization Type Journal Article
Year 2018 Publication Nature Ecology & Evolution Abbreviated Journal Nat Ecol Evol
Volume (up) 3 Issue Pages 374-380
Keywords Animals
Abstract Urbanization can cause species to adjust their sexual displays, because the effectiveness of mating signals is influenced by environmental conditions. Despite many examples that show that mating signals in urban conditions differ from those in rural conditions, we do not know whether these differences provide a combined reproductive and survival benefit to the urban phenotype. Here we show that male tungara frogs have increased the conspicuousness of their calls, which is under strong sexual and natural selection by signal receivers, as an adaptive response to city life. The urban phenotype consequently attracts more females than the forest phenotype, while avoiding the costs that are imposed by eavesdropping bats and midges, which we show are rare in urban areas. Finally, we show in a translocation experiment that urban frogs can reduce risk of predation and parasitism when moved to the forest, but that forest frogs do not increase their sexual attractiveness when moved to the city. Our findings thus reveal that urbanization can rapidly drive adaptive signal change via changes in both natural and sexual selection pressures.
