The role of nutrition on maternal mortality has been long debated in the historical and scientific literature.Some scholars refute any role of nutrition and diet in the decline of maternal mortality, privileging other causes such as the diffusion of professional midwifery and medical and scientific progress, while others are more open-minded about
Sparing zones from mowing has been proposed, and applied, to improve local conditions for survival and reproduction of insects in hay meadows.However, little is known about the efficiency of refuge zones and the consequences for local populations.We studied population densities of butterflies before and after 28 mm mowing in the refuge zone of 15 m
Waxing/waning of the ice sheets and the associated change in thermohaline circulation have played an important role in global climate change since major continental ice sheets appeared in the northern hemisphere about 2.75 million years ago.In the earliest glacial stages, however, establishment of the linkage between ice sheet development and ocean
Seed masting and production of empty seeds have often been considered independently as different strategies to reduce seed predation by animals.Here, we integrate both phenomena 28 mm within the whole assemblage of seed predators (both pre and post-dispersal) and in two contrasting microsites (open vs.sheltered) to improve our understanding of the
