Food webs including parasites, biomass, body sizes, and life stages for three California/Baja California estuaries Food webs including parasites, biomass, body sizes, and life stages for three California/Baja California estuaries
This data set presents food webs for three North American Pacific coast estuaries and a “Metaweb” composed of the species/stages compiled from all three estuaries. The webs have four noteworthy attributes: (1) parasites (infectious agents), (2) body-size information, (3) biomass information, and (4) ontogenetic stages of many animals with complex life cycles. The estuaries are...

Fire and grazing regulate belowground processes in tallgrass prairie Fire and grazing regulate belowground processes in tallgrass prairie
In tallgrass prairie, belowground processes are even more important than in forested systems because aboveground biomass and standing dead litter are periodically removed by frequent fires or grazers. Thus, studies that address factors regulating belowground processes are especially relevant for tallgrass prairie. We predicted that effects of grazing and burning differ belowground and...

Prey: Thamnophis hammondii (Two-striped Garter Snake) Prey: Thamnophis hammondii (Two-striped Garter Snake)
Pox infection has occurrcd in mourning doves in at least 8 states on 12 separate occasions. Unsuccessful attempts were made to transmit both fowl pox (chicken isolate) and passerine pox (cowbird isolate) to mourning doves.

Uncertainty and spatial linear models for ecological data Uncertainty and spatial linear models for ecological data
Models are not perfect; they do not fit the data exactly and they do not allow exact prediction. Given that models are imperfect, we need to assess the uncertainties in the fits of the models and their ability to predict new outcomes. The goals of building models for scientific problems include (1) understanding and developing appropriate relationships between variables, and (2)...
