| phenotype matching in wild parsnip and parsnip webworms: causes and consequences. | according to the geographic mosaic theory of coevolution, selection intensity in interactions varies across a landscape, forming a selection mosaic; interaction traits match at coevolutionary hotspots where selection is reciprocal and mismatch at coldspots where reciprocity is not a factor. chemical traits play an important role in the interaction between wild parsnip (pastinaca sativa) and the parsnip webworm (depressaria pastinacella). furanocoumarins, produced as plant defenses, are detoxifie ... | 2003 | 12778550 |
| using habitat suitability models to target invasive plant species surveys. | managers need new tools for detecting the movement and spread of nonnative, invasive species. habitat suitability models are a popular tool for mapping the potential distribution of current invaders, but the ability of these models to prioritize monitoring efforts has not been tested in the field. we tested the utility of an iterative sampling design (i.e., models based on field observations used to guide subsequent field data collection to improve the model), hypothesizing that model performanc ... | 2013 | 23495636 |
