Trophic Level Asynchrony in Rates of Phenological Change For Marine, Freshwater and Terrestrial Environments

Recent changes in the seasonal timing (phenology) of familiar biological events have been one of the most conspicuous signs of climate change. However, the lack of a standardised approach to analysing change has hampered assessment of consistency in such changes among different taxa and trophic levels and across freshwater, terrestrial and marine environments. We present a standardised assessment of 25 532 rates of phenological change for 726 UK terrestrial, freshwater and marine taxa. The majority of spring and summer events have advanced, and more rapidly than previously documented. Such consistency is indicative of shared large-scale drivers. Furthermore, average rates of change have accelerated in a way that is consistent with observed warming trends. Less coherent patterns in some groups of organisms point to the agency of more local scale processes and multiple drivers. For the first time we show a broad scale signal of differential phenological change among trophic levels; across environments advances in timing were slowest for secondary consumers, thus heightening the potential risk of temporal mismatch in key trophic interactions. If current patterns and rates of phenological change are indicative of future trends, future climate warming may exacerbate trophic mismatching, further disrupting the functioning, persistence and resilience of many ecosystems and having a major impact on ecosystem services

Animism in Rainforest and Tundra: Personhood, Animals, Plants and Things in Contemporary Amazonia and Siberia (Book Review)

Animism is a form of traditional spiritual belief that receives welcome treatment here. The observations of Victorian ethnologist travellers on the local peoples they regarded as primitive was analysed by Sir Edward (E. B.) Tylor, in Primitive Culture (1871) which established the working definition of animism followed by later generations of scholars. This came from the observation that non-scientific people did not always draw sharp distinctions between human persons and other entities such as animals, trees and even rocks but imbued these with soul. The latin anima, ‘soul, spirit’ provided the title of what was assumed to be a primitive religion, animism. The study being reviewed recognizes apparent connections within deep history between Siberia and the Amazon, and uses contemporary social anthropology to clarify assumptions about animism. This book on animism in two shamanic cultures explores personhood and the relations in pre-scientific human thought between humans and non-humans, in contexts where non-humans can be regarded as social persons (p.2).
