Sailing Flight of the Albatross [PDF]
Nature, 1889 MY attention has been drawn to some correspondence in NATURE, May 2 and 9, on the “Sailing Flight of the Albatross,” in which reference is made to my father's letter to Sir William Thomson on the subject. At Sir William Thomson's suggestion, I am now about to condense the rest of my father's correspondence on the subject into a form convenient for ...

Left to Live and Die: Resource Security and the Biopolitics of Land Stockpiling in China
Antipode, EarlyView.Abstract Beginning in 2007, the Chinese state used liberalising policy and funding to encourage the expansion of large‐scale grain farming. Despite this support, many of the new farms have struggled financially and folded. Drawing on Foucauldian biopolitics and resource security literature, I argue that, with modernised agriculture, the state primarily

Effective dispersal of fern spore and the ecological relevance of zoochory
Biological Reviews, EarlyView.ABSTRACT The mechanisms of fern dispersal are under‐studied and there are few data to support the vectors assumed to drive patterns of sporophyte occurrence and speciation. Although wind is generally the fern spore dispersal vector described in the literature, there has always been competing evidence supporting alternate vectors.

Conservation Biology, EarlyView.Abstract The currently circulating high‐pathogenicity avian influenza (HPAI) virus of the subtype H5 causes variable illness and death in wild and domestic birds and mammals, as well as in humans. This virus evolved from the Goose/Guangdong lineage of the HPAI H5 virus, which emerged in commercial poultry in China in 1996, spilled over into wild birds,
