Green space and stress: evidence from cortisol measures in deprived urban communities.
Jennifer Roe,Catharine Ward Thompson,Peter Aspinall,Mark J. Brewer,E. I. Duff,David Miller,Richard Mitchell,Angela Clow +7 more
TL;DR: It is concluded that higher levels of green space in residential neighbourhoods, for this deprived urban population of middle-aged men and women not in work, are linked with lower perceived stress and a steeper (healthier) diurnal cortisol decline.
Journal ArticleDOI
Fine Root Dynamics in a Tropical Rain Forest is Influenced by Rainfall
TL;DR: In this paper, a field study was conducted to determine root biomass, elemental composition and the influence of rainfall on longevity of fine roots in a tropical lowland evergreen rainforest at Danum Valley, Sabah, Malaysia.
Journal ArticleDOI
Contrasting effects of summer and winter warming on body mass explain population dynamics in a food-limited Arctic herbivore.
Steve D. Albon,R. Justin Irvine,Odd Halvorsen,Rolf Langvatn,Leif Egil Loe,Erik Ropstad,Vebjørn Veiberg,René van der Wal,Eirin Bjørkvoll,E. I. Duff,Brage Bremset Hansen,Aline Magdalena Lee,Torkild Tveraa,Audun Stien +13 more
TL;DR: The causes and consequences of variation in body mass of wild female Svalbard reindeer from 1994 to 2015, a period of marked climate warming, provide an important 'missing' mechanistic link in the current understanding of the population biology of a keystone species in a rapidly warming Arctic.
Journal ArticleDOI
Reproducibility of species lists, visual cover estimates and frequency methods for recording high‐mountain vegetation
Pascal Vittoz,N. Bayfield,Rob W. Brooker,David A. Elston,E. I. Duff,Jean-Paul Theurillat,Antoine Guisan +6 more
TL;DR: In this paper, the authors used the GLORIA protocols for species composition and visual cover estimates in percentages on large summit sections (>100 m2) and species composition in nested quadrats (1 m2).
Journal ArticleDOI
Alkyl phenols and diethylhexyl phthalate in tissues of sheep grazing pastures fertilized with sewage sludge or inorganic fertilizer.
TL;DR: It is suggested that the addition of sewage sludge to pasture is unlikely to cause large increases in tissue concentrations of NP and phthalates in sheep and other animals with broadly similar diets and digestive systems grazing such pasture.
