Crop model‐specific biases are a key uncertainty affecting our understanding of climate change impacts to agriculture. There is increasing research focus on intermodel variation, but comparisons between mechanistic ( MM s) and empirical models ( EM s) are rare despite both being used widely in this field. We combined MM s and EM s to project future (2055) changes in the potential distribution (suitability) and productivity of...

San Nicolas Island is surrounded by broad areas of shallow subtidal habitat, characterized by dynamic kelp forest communities that undergo dramatic and abrupt shifts in community composition. Although these reefs are fished, the physical isolation of the island means that they receive less impact from human activities than most reefs in Southern California, making San Nicolas an ideal place to evaluate alternative theories abo...

Ecology Letters (2012) 15 : 475–483 Abstract Studies of consumer‐resource interactions suggest that individual diet specialisation is empirically widespread and theoretically important to the organisation and dynamics of populations and communities. We used weighted networks to analyze the resource use by sea otters, testing three alternative models for how individual diet specialisation may arise. As expected, individual spec...

We determined the source of fatty acids in scleractinian corals by separately measuring and comparing the δ 13 C values of fatty acids in zooxanthellae and coral hosts from two scleractinian coral species ( Montastraea faveolata and Porites astreoides ) from reefs of the Florida Reef Tract. Using an isotopic mass balance approach, we show that zooxanthellae are the dominant source of fatty acids and that in many colonies heter...
