How consumers of plastic water bottles are responding to environmental policies?

How are insects responding to global warming?

Global average surface temperature has increased by around 0.6 oC during the past century, with the 1990s being the warmest decade. Temperature changes vary geographically, greater at higher latitudes; and within the year, greater during the coldest months (Houghton et al. 2001). There is now a consensus that anthropogenic emissions of CO2 and other greenhouse gases are ultimately responsible f...

Scrambling Eggs in Plastic Bottles

This issue of PLoS Genetics contains the second of two important papers describing the high levels of meiotic failure caused by exposure of female mice to a chemical known as Bisphenol A (BPA) [1]. In the first article [2], Pat Hunt and her collaborators demonstrated high levels of meiotic failure in females exposed to BPA, suggesting that BPA exposure affects maturing oocytes. This conclusion ...

Responding to environmental change: plastic responses vary little in a synchronous breeder.

The impact of environmental change on animal populations is strongly influenced by the ability of individuals to plastically adjust key life-history events. There is therefore considerable interest in establishing the degree of plasticity in traits and how selection acts on plasticity in natural populations. Breeding time is a key life-history trait that affects fitness and recent studies have ...

Community challenges when using large plastic bottles for Solar Energy Disinfection of Water (SODIS)

BACKGROUND Communities living in developing countries as well as populations affected by natural or man-made disasters can be left at great risk from water related diseases, especially those spread through the faecal-oral route. Conventional water treatments such as boiling and chlorination can be effective but may prove costly for impoverished communities. Solar water disinfection (SODIS) has ...
