Safe for saplings; safe for seeds ?

Smit, Christian ; Gusberti, Michele ; Müller-Schärer, Heinz

In: Forest Ecology and Management, 2006, vol. 237, no. (1-3), p. 471-477

In wood pastures spatial associations of tree saplings with nurse structures such as unpalatable plants are generally explained as associational resistance; i.e. reduced herbivory by association with a defended neighbour. However, these associations may result from other underlying processes that occur at the seed stage. Here we tested whether the observed associations between...

Quid pro quo in IPOs : why book-building is dominating auctions

Degeorge, François ; Derrien, François ; Womack, Kent L.

The book-building procedure for selling initial public offerings to investors hascaptured significant market share from auction alternatives in recent years, despite significantly lower costs in both direct fees and initial underpricing when using the auction mechanism. This paper shows that in the French market, where the frequency of book-building and auctions was about equal in the 1990s, the...

Winter weather affects asp viper Vipera aspis population dynamics through susceptible juveniles

Altwegg, Res ; Dummermuth, Stefan ; Anholt, Bradley R. ; Flatt, Thomas

In: Oikos, 2005, vol. 110, no. 1, p. 55-66

Detailed studies on mammals and birds have shown that the effects of climate variation on population dynamics often depend on population composition, because weather affects different subsets of a population differently. It is presently unknown whether this is also true for ectothermic animals such as reptiles. Here we show such an interaction between weather and demography for an ectothermic...
